Subject: [PATCH 001/376] feat(desktop): per-profile scope selector in the
 Capabilities view (#86548)
MIME-Version: 1.0

* feat(desktop): per-profile scope selector in the Capabilities view

Adds a 'Configuring:' profile selector above the Tools and MCP tabs in the
Capabilities (Skills) view, so a user can configure ANY profile's toolsets
and MCP servers without switching the whole app into that profile.

- hermes.ts: every capability fetcher (getToolsets, setToolsetEnabled,
  getToolsetConfig/Models, selectToolsetModel/Provider, runToolsetPostSetup,
  getMcpCatalog, installMcpCatalogEntry, testMcpServer, saveMcpServers,
  auth/oauth flow, setEnvVar/deleteEnvVar/revealEnvVar, startOAuthLogin/
  pollOAuthSession, getActionStatus, getHermesConfigRecord) takes an optional
  trailing profile? that forwards to profileScoped(profile). Omitting it
  preserves exact app-wide behavior (profileScoped(undefined) → _apiProfile).
- use-config-record.ts: hermesConfigKey(profile)/useHermesConfigRecord(profile)/
  hermesConfigCacheWriter(profile) — per-profile RQ keys (scope-in-key).
- toolset-config-panel.tsx + mcp-tab.tsx: thread profile through every fetch
  and their nested children (EnvVarField, PostSetupRunner, ModelCatalogPicker),
  keyed/remounted per selected profile so switching never shows stale state.
- skills/index.tsx: the selector (seeded from profiles.list, default→'Hermes',
  shown only with >1 profile), defaulting to ; toolsets
  query + toggles keyed and scoped to the selection; McpTab/ToolsetDetail
  remounted per scope.
- i18n: skills.configuringProfile (en + zh; others fall back).

When the selected profile equals the active one (the default), behavior is
identical to before — the selector is a pure override layered on top.

Tests: index.test.tsx — new case asserts picking a non-active profile in the
selector refetches toolsets scoped to that profile; existing single-profile
cases still pass (selector hidden with one profile). 5/5. Full-project tsc clean.

* Fix CI: command-palette getHermesConfigRecord call, panel test mock, lint

- command-palette/index.tsx: getHermesConfigRecord now takes an optional
  profile; passing the bare fn as queryFn fed it react-query's context object
  (TS2769 + mcp_servers on {}). Wrap in an arrow.
- toolset-config-panel.test.tsx: use-config-record now imports normalizeProfileKey
  from @/store/profile, which calls setApiRequestProfile at module-init; the
  full-replacement @/hermes mock must provide it (+ getApiRequestProfile).
- index.test.tsx selector test: stub Element.prototype.scrollIntoView (Radix
  Select calls it on open; jsdom lacks it).
- toolset-config-panel.tsx: PostSetupRunner useCallback missing 'profile' dep
  (stale-closure correctness); jsx-prop sort order.

Verified in a full-dep checkout: tsc 0 errors, eslint clean, panel 28/28 + skills 5/5.

Subject: [PATCH 003/376] fix(send_message): hand unresolved cron and react
 targets to the adapter again

Restores pass-through behavior for cron delivery and react/unreact that
was lost when d409f6748 routed them through resolve_send_target. Stored
cron job targets the channel directory doesn't recognize (e.g.
telegram:ops-room on a fresh install, photon group GUIDs) used to go to
the adapter verbatim; after d409f6748 they were silently dropped. Same
for react on platform-native ids.

Adds an opt-in pass_unresolved_references flag to resolve_send_target,
passed only by cron and react. Model-facing send tool stays strict.
Plugin platforms with a parser stay strict for all callers. The optional
validator still has the final say over passed-through ids.

Follow-up fixes on salvage:
- Update test_cron_relay_delivery_guards.py mock lambdas to accept **kw
  (file added to main after PR branch point; lambdas didn't accept the
  new keyword argument)
- Consolidate duplicated pass-through blocks into _pass_through_unresolved
  local helper

Fixes #85128

Subject: [PATCH 004/376] fix(telegram): hold inbound messages across
 disconnect instead of destroying them
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The disconnect drop-guard (#55971) correctly prevents dispatch into a
torn-down session. Destroying the event was wrong: by enqueue/flush time
python-telegram-bot has already acked the update and advanced the polling
offset, so Telegram never redelivers. Result: silent permanent loss, no
log, no error.

Hold inbound events (text/photo/media-group) when the drop-guard fires,
salvage pending batch maps on teardown, cancel+await the redispatch task
in the delivery cancel map (lifecycle-tracked), and redispatch from
_mark_connected after reconnect. Cap the hold queue (default 64), dedupe
by object identity, discard on non-retryable fatal. Cancel-after-pop in
flush paths also holds.

Distinct from #72037 (cancel-after-pop during follow-up supersession) and
#81528 (boundary discard). Tests use delay=0 and entered/release Events —
no wall-clock races; includes production terminal-step coverage.

Subject: [PATCH 005/376] fix(telegram): close hold-lifecycle gaps on permanent
 fatal and connected drain
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Address review on #83878:

- Permanent fatal fences all hold producers and discards pending maps on
  teardown instead of re-populating a queue that can never drain.
- Any hold created while connected schedules a tracked redispatch (cancel-
  after-pop no longer orphans until a future reconnect).
- Redispatch failures re-hold current + remainder without tight-looping.

Regression coverage for the three residual paths, plus the interaction
with OOF-156's connect-failure classification: the retryable network
path (telegram_connect_error) must NOT clear the hold queue — reconnect
is precisely what drains it; only non-retryable fatals discard.

Subject: [PATCH 006/376] fix: standardize media-group CancelledError to raise

Pre-existing inconsistency: _flush_media_group_event used return
in CancelledError while _flush_text_batch and _flush_photo_batch
used raise. Changed to raise for consistency and to properly
propagate task cancellation. Made more visible by the hold-queue
changes in #83878.

Subject: [PATCH 011/376] fix(desktop): expand HUD transcript when resized

Use the available HUD window height for non-empty transcript scrollback instead of a fixed glance-band cap. This makes the corner resize affordance reveal additional conversation content while preserving the compact empty HUD state.

Subject: [PATCH 015/376] fix(desktop): drop pending stream rows whose reply
 the transcript already carries
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A still-pending assistant stream row (id `assistant-stream-*`) whose reply
the authoritative transcript already committed used to fall through to
`preserved.push` when ordinal pairing missed it — the commit shifted the
row's ordinal under compaction/history rewrites, so `nextByRoleOrdinal`
returned nothing and the local copy was appended to the tail, rendering the
same answer twice (reported as A B C D E C D tail duplication).

The #70209 guard only covers SETTLED local rows (`pending !== true`);
pending rows were unprotected. Match pending rows against SETTLED
authoritative rows before appending:

- identical answer text            -> authoritative already carries it
- authoritative extends local text -> authoritative is the settled final
  version of the still-streaming local copy
- local extends authoritative text -> replace the committed row with the
  richer local body instead of appending

Live projection shells (still-pending candidates) never match, so the
traces-only local row keeps replacing the empty shell.

Subject: [PATCH 016/376] fix(desktop): settle final reply onto interim even
 after message.start reset the boundary flag

completeAssistantMessage merged a turn's final text onto its sealed interim
bubble only when the session's volatile interimBoundaryPending flag was still
true. A subsequent message.start (chained turn, follow-up, or mid-turn
compaction) resets that flag to false; when it landed between the same turn's
message.interim and message.complete, the flag-based gate fell through and the
UI appended a duplicate bubble.

Key the merge on the message's OWN durable interim state instead of the
session flag. finalContinuesInterim already requires existing.interim plus
prefix continuity, so distinct replies (which don't continue the interim) are
still appended as their own bubble.

Adds a regression test: interim + message.start + completing final that
continues the interim must yield one bubble, not two.

Sweeper review on #76583: dropping interimBoundaryPending from the

(interim('old') → message.start → complete({response_previewed: true,

with no prefix guarantee, so it must stay flag-gated; only
finalContinuesInterim (prefix-either-way continuity, which can only hold
for the same message) settles flag-free. New test: distinct previewed
final after a reset appends its own bubble. Production ordering cited in
the test: compaction-resume events exclude message.start
(gateway-event.ts), and the TUI gateway emits message.complete before
goal-followup starts (tui_gateway/server.py).

74/74 use-message-stream tests pass.

Subject: [PATCH 018/376] fix(desktop): stop empty REST transcript refresh from
 wiping a warm resume

session.activate's persisted-transcript refresh reconciled unconditionally
against getLatestSessionMessages, so a transient empty REST page (e.g. a
backend respawn racing its own state.db read after a wake/reconnect) wiped
a transcript the activate response had just restored. Guard it the same way
the activate payload itself already is guarded a few lines above: an empty
authoritative page never overrides a non-empty cached transcript.

Subject: [PATCH 027/376] fix(desktop): normalise timeout/error subagent
 statuses to terminal (#73728)

The backend emits terminal statuses including 'timeout' and 'error' in
subagent.complete payloads, but asStatus() only recognised 'completed',
'failed', 'interrupted', and 'queued'. Unrecognised values fell through
to 'running', making timed-out subagents immortal in the active status
stack.

Fix: map timeout/error to 'failed', cancelled/canceled to 'interrupted'.
Nonterminal unknown statuses still default to 'running' for forward
compatibility.

Fixes #73728

Subject: [PATCH 028/376] fix(desktop): fail closed on unrecognized
 subagent.complete statuses; surface timeout reason
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Follow-up to the #73728 normalization fix (supersedes the event-agnostic
fallback the maintainers flagged as incomplete):

- subagent.complete is terminal by definition — an unrecognized status on
  it now renders as 'failed' instead of falling through to 'running',
  which would recreate the immortal false-active row for any future
  backend status (the keep_open request on #73859).
- Live events keep the lenient 'running' fallback.
- Synthesize a 'Timed out after Xs' summary from duration_seconds when
  the backend completes with status 'timeout' and no summary, so the
  failed row explains itself.
- Tests: timeout reason synthesis + pruning, event-aware fail-closed vs
  lenient live fallback (13 total).

Review feedback: prev?.summary could shadow the 'Timed out after Xs'
reason when a live event had populated it. timeoutSummary() now wins for
raw timeout status; add coverage for the missing-duration placeholder.

 timed-out subagent row
MIME-Version: 1.0

Content-Transfer-Encoding: 8bit

Folded-in coverage from PR #80045 (gannotti, #80018): after a terminal
subagent.complete, a stray late 'running' progress event must not restart
the spinner — the upsert guard keeps the settled failed status.

Subject: [PATCH 032/376] fix(desktop): widen terminal-status handling to
 sibling sites

Two sibling sites still treated only 'completed'/'failed' as terminal:

- delegate-model.ts settled result rows as 'completed' for ANY status other
  than 'failed', so a delegate result row with status 'timeout' or 'error'
  (the statuses tools/delegate_tool.py actually emits on child timeout or
  crash) rendered behind a green check. Settled rows now map ok/completed
  to completed and everything else to failed.
- subagents.ts asStatus accepted a literal 'queued' payload status even on
  a subagent.complete event, leaving the row active forever. The fail-closed
  branch now runs before the queued fallback, so completion events always
  settle.

Subject: [PATCH 034/376] fix(tui_gateway): stop replaying live-turn user text
 after redirect

A mid-turn correction (Desktop session.redirect / busy-input interrupt redirect)
must not leave a server-queue self-copy of the live inflight user prompt.
Otherwise post-turn _drain_queued_prompt restarts that original text as a
fresh agent turn after Q completes (#84417).

Scrub text-only self-duplicates of inflight_turn.user on successful
redirect/steer, refuse admitting them in _enqueue_prompt, rewrite merged
"{P}\n\n{Q}" slots to Q-only, bump _queued_prompt_generation on compression
session rotation, and restore the claimed queue envelope when generation
cancels mid-drain. Stabilize profile-scoped agent-build unit tests under CI load.

Fixes #84417

Subject: [PATCH 035/376] fix(tui_gateway): keep steer-mode fall-through bursts
 queued instead of interrupting

Desktop/TUI busy-input `steer` mode escalated any fall-through message
(steer() rejected, raised, or a non-steerable multimodal payload) into a
hard interrupt of the live turn. AIAgent.interrupt() also clears the
pending steer buffer, so a burst of user messages sent while the agent
was busy could be silently destroyed: earlier successfully-steered
messages were dropped from the buffer and the live turn was killed.

Steer-mode fall-throughs now keep pure queue semantics: preserved FIFO
in queued_prompt/queued_prompts and drained on turn end, per the
existing steer contract. Only explicit `interrupt` mode still fires
_interrupt_busy_session. No synthetic user messages are injected
mid-loop; accepted steers continue through the sanctioned OOB
steer-marker path.

Regression tests cover: rejected steer queues without interrupting,
steer exception falls back to queue, multimodal payload queues, a mixed
burst preserves accepted steers plus the queued fall-through, and a
fall-through burst drains all texts FIFO after turn end.

Fixes #86134

Subject: [PATCH 036/376] fix(desktop): interrupt-first after Stop so
 edit/resend avoids session-busy

Stop clears frontend busy immediately while the gateway may still wind
down. Edit/restore then passed interruptFirst=false and raced 4009
session busy. Keep a short per-session cooldown after cancel so rewind
still interrupt-first, and expire the submit-in-flight lock so a hung
submit cannot block the session forever.

Fixes #83855

Subject: [PATCH 037/376] fix(desktop): prove submit target belongs to selected
 session from both directions (#65328)

Fail closed on missing ownership cache entries and prove runtime ownership
forward+reverse against runtimeIdByStoredSessionIdRef before prompt.submit.
Thread the ownership cache through main wiring and session-tile submit.
Adds regression tests for forward mismatch, reverse-only proof, positive
map control, and cache-miss resume.

Closes #65328.

Content-Transfer-Encoding: 8bit

Follow-ups on top of the two salvaged commits:

- widen the #83855 recently-interrupted cooldown to the session-tile
  interrupt path (use-session-tile-delegate.interruptSession) — same race
  class, sibling call site: a tile Stop also clears busy before the
  gateway settles, so a quick tile edit/resend raced 4009 session busy.
  The recovered runtime id is marked too.
- regression test for the tile cooldown.
- refresh three #65328 ownership-proof assertions to tolerate the
  omit_messages flag main now sends on session.resume (toMatchObject).
- eslint import-order fix in utils.test.ts.

Subject: [PATCH 042/376] [verified] fix(desktop): reveal active clarify
 prompts

Reveal a blocking clarify card by re-arming the existing thread bottom-scroll bridge after the request row is hydrated. Keep background-session prompts isolated to their needs-input indicator.

Refs #53666.

Subject: [PATCH 045/376] fix(desktop): replay pending clarify prompts after
 reconnect
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Clarify prompts share the same emitted-while-detached failure class the
pending-approval replay fixed: `clarify.request` rides `_block()`'s pending
registry, so a client whose transport was down when the event fired never
sees the question and the agent thread stays parked until timeout.

Widen the resume snapshot the same way:

- tui_gateway/server.py: `_live_session_payload` now carries
  `pending_clarify` — a read-only snapshot of the clarify prompt still
  blocking the session, scoped to the owning runtime sid. The registry stays
  authoritative; the embedded request_id resolves via clarify.respond.
- Desktop resume paths (`use-session-actions`) restore the parked clarify
  into the clarify store (multi_select preserved) and flag needsInput,
  mirroring restorePendingApproval on both the activate and resume paths.
- pending_approval replay now also forwards the queue-injected request_id so
  the restored prompt responds with exact-request correlation.
- Tests: server-side replay + scoping test; harmonized the #82087 replay
  test with the request_id `_ApprovalEntry` now injects.

Subject: [PATCH 049/376] test(desktop): pin the tail-only contract for the
 loading and stall indicators

Regression coverage for #68634. The indicator family mounts only on the
thread's any-role tail (ba756333): a running bubble that is not the tail
stays silent, even when only a user or system row trails it, and the
optimistic-placeholder flow renders exactly one status row, the
placeholder's own.

Mutation-checked: relaxing the mount gate to a last-assistant walk fails
the two silence cases, and removing the gate fails all five.

Subject: [PATCH 051/376] test(gateway): pin get_update_result in
 metadata-mirror snapshot test

The test compares two _session_info snapshots taken at different times; the background update-check thread can complete between them and flip update_behind (None -> -1), making the equality assertion flaky once the suite runs long enough. Pin the value via monkeypatch.

Subject: [PATCH 054/376] test(todo): make JSON-string coercion test
 order-agnostic

The type-coercion test pinned index order of todos, which #42649's
_normalize_order intentionally changes (in_progress lifts ahead of
earlier pending rows). Assert coercion by id instead of position.

Subject: [PATCH 055/376] fix(desktop): sort survivors by last_active in
 mergeSessionPage to prevent stale sidebar order

When multiple sessions are active/settled simultaneously, survivors
(sessions the server omitted from the fresh page) were prepended as a
block in their old relative order from the previous $sessions array.
This caused recently-interacted sessions to appear below older ones.

Now survivors are sorted by last_active descending and merged into the
incoming array at the correct position using a two-pointer merge,
so the sidebar always reflects true recency.

Fixes #47203

Subject: [PATCH 056/376] fix(desktop): compare pinned/archived in the session
 list signature
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`refreshSessions` swaps the session page into `$sessions` only when
`sameCronSignature` reports a change, and that signature compared row
content — id, lineage root, title, source, profile, preview,
message_count, last_active, ended_at — but not row state. A page whose
only delta was `pinned` was judged identical and discarded, so the row
cached in the atom kept its old flag indefinitely. An idle conversation
never moves any of the compared fields again, which is exactly the kind
a user goes and unpins.

`session-pin-sync` treats that row as authoritative. Its write guard
(daeedf67c) is released by a page that CONFIRMS the value it wrote, and
falls back to letting the server win once WRITE_GUARD_MS elapses with no
confirmation. Because the confirming page was filtered out one layer up,
the fallback was the only branch that ever ran: ~10s after an unpin the
next reconcile read the frozen `pinned: true` row and called
pinSession() again. Adoption marks the id `mirrored`, so the push pass
never corrected the backend either — the local pin set and
sessions.pinned drifted apart permanently, which is why four of five
pins rendered in the sidebar read pinned=0 in state.db.

Compare both flags so a pin-only page reaches the atom. That restores
the guard's confirm path and makes WRITE_GUARD_MS a backstop again
rather than the load-bearing branch. `archived` is included for the same
reason: it is row state a consumer reads. Neither flag moves outside a
deliberate user action, so the churn the gate exists to prevent is
unaffected.

The existing `releases the guard once a page confirms the written value`
test passes on main because it hands `$sessions` the confirming page
directly — the gap was in the pipeline that decides whether such a page
is ever delivered.

Fixes #76919

Subject: [PATCH 057/376] fix(desktop): dedupe persisted sidebar order ids to
 stop duplicate repo headers

The desktop sidebar persists repo/lane order in localStorage
(hermes.desktop.workspaceParentOrder / workspaceOrder). If that saved
list ever contains the same id twice, orderByIds() pushes the matching
item once per occurrence, rendering the same repo header twice inside a
project. reconcileFreshFirst() then preserves the duplicates, so the
corruption self-perpetuates across restarts and storage clears.

Verified on a live install: the persisted workspaceParentOrder contained
the same repo path at two positions, the backend project tree was clean,
and the duplicated header matched the duplicated id.

Treat persisted UI order as untrusted input: orderByIds() now skips ids
it has already emitted, and reconcileFreshFirst() dedupes the retained
tail so the next persist writes a clean list (self-healing).

Subject: [PATCH 058/376] fix(desktop): keep the session-list merge/dedup/order
 pipeline invariant-consistent

Completes the sidebar order/visibility class on top of the three salvaged
contributor commits:

- mergeSessionPage (#47203): interleave survivors against the
  title-preserving merged rows using the backend's effective-recency key
  (last_active with a started_at fallback), tie-preferring survivors so
  keep-set rows with no timestamps retain the old prepend contract.
- sidebar order helpers (#73314): dedupe live ids as well as persisted ids
  in reconcileFreshFirst/reconcileOrderIds/orderByIds so the shared-git-root
  flatMap path can neither render one repo once per project nor write the
  duplicates back into localStorage (the persisted feedback loop).
- Pinned section (#85969): resolvePinnedSessions falls back to the server
  `pinned` flag when the localStorage pin set is cold or clobbered, so a
  backend-pinned row is never simultaneously filtered out of every list and
  absent from the Pinned section (the "session vanishes entirely" state).
  session-pin-sync then adopts the pin locally on its next reconcile.

Regression tests cover survivor interleaving with optimistic bumps and
started_at fallback, duplicate live/persisted id dedup, and pin resolution
fallback (cold cache, lineage-root pins, undefined flag on old backends).

Subject: [PATCH 060/376] fix(desktop): order mid-turn user messages after the
 assistant output that predates them
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A message typed while a turn streamed rendered ABOVE assistant output the
user had already watched arrive (#73793), and the retired
insert-before-the-active-reply fallback could splice the bubble mid-thread
— halfway up the chat — when the stream id was missing or stale (#83151).

Fix the class at every path that assigns a transcript position to a
mid-turn user message:

- New shared appendMidTurnUserMessage (rewind.ts): seal the live stream
  bubble in place (interim), append the correction at the live tail, and
  clear streamId so post-redirect deltas seed a fresh bubble BELOW the
  correction. Used by both the primary composer redirect path
  (use-prompt-actions) and the session-tile steer path
  (session-tile-actions), replacing the insert-before splice and its
  last-assistant mid-thread fallback.
- appendLiveSessionProjection now projects the resume/reload turn in
  arrival order (prompt → streamed output → correction → post-redirect
  output) instead of prompt → corrections → reply, so the projection
  agrees with the live transcript and messages no longer jump upward on
  reconnect. With the gateway's new correction_offsets the flat dump is
  split at each accepted-correction boundary; without offsets the
  corrections follow the projected reply.
- tui_gateway/server.py records correction_offsets (assistant text length
  at each accepted correction) on the inflight turn and carries them in
  _inflight_snapshot, only when complete, so resume can rebuild true
  arrival order. Older gateways/clients degrade cleanly.
- preserveLocalPendingTurnMessages and the projection's latest-user-run
  matcher now treat a live-tail assistant row between the prompt and its
  correction as part of the same turn's run, so arrival-ordered runs
  survive refreshes without dropping the prompt.

Fixes #73793. Fixes #83151.

Subject: [PATCH 062/376] fix(desktop): cold start no longer hides Cloud agents
 until Portal re-login

Fixes #73495. Two cold-start defects made the configured Hermes Cloud
agent vanish after a Desktop restart even though the persisted Portal
session was still renewable:

1. hasLivePortalSession() trusted the FIRST cookies.get() on the lazy
   `persist:` partition. It now reuses the warmOauthCookieStore()
   warm-up + bounded reread that hasLiveOauthSession() gained in
   PR #67769, so a single hydration false-negative no longer clears the
   agent list and flips the panel to signed-out.

2. Discovery required the short-lived `privy-token` access cookie but
   treated its absence as a full interactive re-login, even when the
   30-day `privy-session` / `privy-refresh-token` renewal cookies
   survived the process exit. New cookiesHavePrivyAccessToken() splits
   "signed in (renewable)" from "discovery can succeed right now";
   discoverCloudAgents() and cloudAgentSilentSignIn() now mint a fresh
   access token via one bounded, hidden, deadline-capped portal load
   (renewPortalAccessSilently) before or after a 401, and only surface
   needsCloudLogin when renewal genuinely cannot complete.

PRIVY_SESSION_COOKIE_VARIANTS also learns `privy-refresh-token` so a
renewal-only jar still counts as signed in rather than demanding an
interactive login while usable refresh material sits in the partition.

Tests: connection-config.test.ts covers the access/session split,
including the exact renewal-only cold-start jar from the issue repro.

Subject: [PATCH 065/376] fix(desktop): keep session-list scrollbar clickable
 beside pane sash
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The pane-resize sash's 9px grab band was centered on the split boundary,
so ~4.5px reached into the leading pane and sat exactly on top of the
session list's 4px scrollbar — the pointer always hit the sash (cursor
flipped to col-resize) and the scrollbar thumb was unclickable/undraggable.

Make the grab band asymmetric: 1px into the leading pane, 7px into the
trailing one. The scrollbar regains its full hit area while the sash stays
an easy 8px target; the hairline and hover strip are repositioned onto the
actual boundary.

Fixes #79157

Subject: [PATCH 067/376] fix(desktop): clear stale turn state after lost
 stream events

Three safeguards keep finished chats from looking busy: tool rows seal on turn settle, vanished runtimes clear awaiting state and open tool parts, and late stream events no longer land in a freshly opened session.

Subject: [PATCH 068/376] fix(desktop): keep session marked in-progress during
 async delegation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Salvaged from #51358 (razultull), rebuilt against the rewritten status
architecture on main. The original PR patched setSessionWorking /
noteSessionActivity / the statusbar counter, all of which have since been
replaced (busy now lives in session-states.ts, the watchdog only marks
stalled, and the statusbar Agents item already shows a pure subagent count
— the conflated counter the PR split no longer exists).

What still applied is the core bug: a parent that delegates via
delegate_task(background=true) ends its own turn the moment the handle
returns, so the sidebar row dropped to a plain idle dot while the spawned
subagents kept working for minutes — the session read as "done" mid-task.

Add $delegatingSessionIds — sessions whose subagents are still queued or
running — as an input to the session dot projection, claiming the same
'background' treatment as running background processes (and yielding to
'working' while the parent turn itself is live). Uses the same
runtime→stored bridge, lineage aliasing, and fresh-chat runtime-id
fallback as $backgroundRunningSessionIds, and clears by construction the
moment the last subagent reaches a terminal status.

Subject: [PATCH 070/376] fix(desktop): don't let a stale resume snapshot mark
 an open chat idle
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fixes the #70449 symptom that remained after the two salvaged commits:
opening or viewing a chat whose turn is still running cleared its working
indicator. `session.activate` / `session.resume` report `running` as a
snapshot taken when the RPC was issued; a turn that started or kept
streaming while the RPC was in flight has already marked the runtime busy
in the live cache, and both resume paths overwrote that newer truth with
the stale `running: false`, dropping the session out of the working set
and painting it done mid-turn.

Add `resolveResumedBusy`: a snapshot saying running always wins (adopting
a live turn is never stale), but a snapshot saying idle can no longer
rewind a live busy — the turn's own terminal signal (running:false via
session.info / the settle path) stays the only authority that ends it,
and the background-sync reaper still clears truly lost turns. Wired into
both the warm `session.activate` path and the cold `session.resume` path,
reading the freshest cache entry rather than the pre-await state.

Includes an eslint --fix formatting pass over the touched files.

Subject: [PATCH 072/376] fix: detect in-stream error chunks in SSE streaming
 path

Some OpenAI-compatible providers (DeepInfra, etc.) return validation
errors as in-stream SSE chunks: HTTP 200 with choices=None and
error_type/error_message in model_extra. The streaming loop silently
dropped these chunks, causing EmptyStreamError ("empty stream") and
pointless retries on the same bad request.

Fix: check for error_type/error_message on chunks with no choices
before skipping. When found, raise RuntimeError with the provider's
error message so the error classifier can properly handle it.

Fixes #65631

Subject: [PATCH 074/376] fix(cron): make immediate execution race-safe

- claim_job_for_fire returns the atomically claimed snapshot with a unique
  fire owner; heartbeat_fire_claim renews the lease; mark_job_run fences
  terminal writes by expected_fire_owner so a stale worker cannot record
  over a replacement claim.
- run_one_job heartbeats the fire claim and forwards a combined cancel
  event (ownership loss OR external cancel) into run_job; the agent path
  is interrupted cooperatively and script-based jobs (no_agent + pre-run
  scripts) are hard-stopped with a process-tree kill (POSIX killpg
  SIGTERM then SIGKILL for surviving group members; Windows
  taskkill /T /F), with a bounded pipe drain so a SIGTERM-ignoring
  descendant cannot wedge the worker on communicate() EOF.
- Shutdown interruption is scoped to the exact execution token instead of
  the bare job ID, so a replacement run of the same job never consumes a
  stale interrupted flag.
- fire_claim_fence serializes save/deliver side effects per profile+job
  with a cross-process flock; remove_job prunes the fence-lock entry.
- Preserves upstream BaseException terminal recording (#73973),
  completed one-shot retention (#80624), blocked_config preflight
  (T1-26), and the advance_next_runs batch on top of current main.

Subject: [PATCH 075/376] fix(cron): harden gateway fire admission and provider
 compatibility

- The gateway api_server fire webhook acknowledges 202 only after a
  durable claim + execution row exist (admission failure stays retryable
  as 503; a live claim answers 200 duplicate), then dispatches the
  claimed snapshot with the live runner adapters (delivery parity with
  the built-in ticker, including relay-fronted and E2EE platforms).
- Legacy single-phase providers (a documented fire_due override without
  split hooks) keep being driven through their own hook. Capability
  detection now credits claim_fire AND fire_claimed overrides, so
  Chronos is correctly classified split-aware (its re-arm lives in
  fire_claimed; the redundant fire_due passthrough override is removed).
- Multi-profile dashboards fail closed for external providers: an
  unscoped reconcile would disarm other profiles' armed one-shots in the
  shared NAS registry.
- Manual runs (cronjob run) carry the owner-bearing claimed snapshot
  through every entry point, composing with upstream's manual-run
  heartbeat (#76502) and background dispatch.

Note: current main moved the dashboard NAS webhook to a pure
forward-to-gateway design (the gateway owns execution and live
adapters), so the dashboard-side claim/tracking machinery from earlier
revisions of this PR is dropped; the durable admission contract lives in
the gateway webhook path.

Subject: [PATCH 076/376] fix(cron): add reliable trigger feedback in Web and
 Desktop clients
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Shared per-job trigger controller (apps/shared) coalesces duplicate
  clicks for the same profile+job inside a mounted client while letting
  unrelated jobs run independently; the backend durable claim remains
  authoritative across windows/processes.
- Two-phase feedback everywhere: the action stays disabled/spinning
  while the request is in flight and the terminal success/error is
  reported once, after the HTTP response — no premature success toast
  (Web), matching the Desktop info notification.
- Desktop keeps the 24h trigger timeout for the synchronous long
  operation and fences stale profile/list responses and unmounted
  surfaces; the sidebar trigger button shows a spinner while busy.

Subject: [PATCH 077/376] fix: compare base-URL hostnames, not substrings, in
 provider-identity checks

Port of the bug class from earendil-works/pi#7933 (DeepSeek base-URL
detection matched by raw substring, missing case variants and matching
lookalike URLs). Hermes had the same class at five sites:

- cli_agent_setup_mixin.py: keyless-custom-endpoint detection treated any
  URL containing the OpenRouter host substring (path segment, lookalike
  domain) as OpenRouter, and missed case variants of the real host.
- models.py validate_requested_model: same substring check for routing an
  openrouter provider with a custom base_url to the custom catalog.
- runtime_provider.py: local-endpoint autodetect matched the string
  localhost anywhere in the URL, including remote hostnames containing it.
- gateway/run.py: /status endpoint display, same local-host substring.
- agent_runtime_helpers.py: Nous Portal cache-layout detection matched
  the nousresearch substring anywhere in the URL.

All sites now use the existing base_url_host_matches / base_url_hostname
helpers (exact host or subdomain, case-insensitive). Regression tests
proven to fail against the old predicates.

Subject: [PATCH 080/376] fix(gateway): match the profile-namespaced session
 key in the clarify bypass lookup

Fixes #82975.

The adapter-level clarify reply bypass in gateway/platforms/base.py's
handle_message() built its session_key via build_session_key(...)
without a profile= argument, defaulting to the legacy agent:main
namespace. The runner registers pending clarifies under
SessionStore._generate_session_key()'s key, which DOES include
profile=self._resolve_profile_for_key(source). Under a named-profile
multiplex these diverge, so the bypass lookup at
clarify_gateway.get_pending_for_session(session_key, ...) misses --
the user's answer to a pending clarify() gets routed to the adapter's
busy-session queue instead of resolving it. The turn then hangs until
the clarify's 3600s timeout, with no inbound message: log line and no
"Gateway intercepted clarify text response" log line, matching the
reported Telegram symptom exactly.

Verified the divergence directly: _resolve_profile_for_key() returns
None when multiplex_profiles is off (default) -- byte-identical to
the prior implicit profile=None, so this only changes behavior for
multiplexed deployments, matching the issue's exact reported scope.

Fixed by using the same self._session_store._resolve_profile_for_key()
the runner's key generator calls, guarded with getattr() + a None
fallback since _session_store is set via a setter and can be unset
for adapters that never call set_session_store() -- preserving prior
behavior for any such adapter rather than introducing a new crash.

Added a regression test alongside the existing bypass coverage: with a
mocked session_store configured for profile multiplexing, a clarify
registered under the profile-namespaced key must still be found and
resolved (not routed to the busy queue). Verified as a genuine
regression by reverting the fix and confirming the new test fails
with the exact reported symptom (the message handler never gets
awaited -- the clarify lookup misses).

21/21 pass across the five directly related clarify test files;
16/16 across the broader multiplex/clarify-progress test files (no
regression).

Subject: [PATCH 081/376] fix(clarify): preserve resolved answers when
 clear_session races a button response

Session-boundary cleanup (gateway/run.py: run-finalization and prompt
delivery-failure paths) calls clear_session to cancel pending clarifies.
It unconditionally overwrote every entry's response with the empty
cancellation sentinel, even entries already resolved by a button callback
or text intercept. A waiter that had already observed the resolved event
would then return the empty sentinel instead of the real answer, silently
discarding the user's response on /new, gateway shutdown, or cached-agent
eviction.

First-writer-wins: clear_session now cancels only entries whose event is
not yet set; already-resolved entries keep their response. Mirrors the
guard resolve_gateway_clarify gained for the same contract. Reported by
doryani-ai on PR #75732; regression test covers the button-then-cleanup
interleaving.

Subject: [PATCH 082/376] fix(gateway): don't restart supervised services on
 clean exit
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The s6 finish script for profile-gateway services restarted on ANY exit
except EX_CONFIG (78) — including clean exit 0. Restart-on-normal-exit
turns an intentional stop into a reconnect loop: the ashriel-discord
storm in #76435 made 1,000+ connections and got the bot token reset by
Discord.

The finish script now exits 125 (permanent failure, no restart) for both
clean exit 0 and EX_CONFIG; only non-zero, non-78 exits (genuine crashes)
restart normally.

Scope note: #76435 bundles a second, separable symptom (Windows desktop
updater showing the literal 'managed outside dashboard' sentinel). Its
root cause is undiagnosed and #22733 covers the dialog-explanation path;
this PR is the gateway half only.

Tests: behavioral — the rendered finish script is executed via sh for
exit codes 0/78/1/137, asserting no-restart for clean stop and fatal
config, restart for crashes. Pre-existing EX_CONFIG test still passes.

Subject: [PATCH 084/376] test: cover tool-message dedupe and latest paging for
 include_compacted (#80680)

Dedupe key now includes tool_call_id/tool_calls/tool_name: compaction
copies carry those fields verbatim, so identical tool messages across
generations still collapse, while distinct tool calls sharing
role/content/timestamp are never merged. Add endpoint-level coverage
for the desktop's real read path (limit + order=latest +
include_compacted=true).

Subject: [PATCH 087/376] fix(desktop): bound inflight journal persistence
 (#63047)

The desktop journal synchronously read, parsed, cloned, and rewrote one
aggregate localStorage value while streamed turns were repainting. Large
tool results and multi-session state could therefore block the renderer and
leave the app unresponsive, while the existing macOS diagnostic path lacked
a real native hide/restore regression check.

Store bounded recovery projections under per-session keys, migrate legacy v1
data once, isolate quota and storage failures, and preserve the newest
recoverable tail without allowing oversized writes to replace valid state.
Add a real Electron/CDP macOS-arm64 A/B harness with native visibility control,
renderer heartbeat and Settings/composer/transcript checks, plus focused
regressions. Keep bulk tool payloads, diagnostics, and the existing recovery
merge behavior out of the hot path.

Fixes #63047

Subject: [PATCH 088/376] test(desktop): spy on the active localStorage
 implementation (#82832)

The inflight journal regression test always spied on Storage.prototype,
but Node 26's jsdom setup can provide a plain in-memory localStorage fallback.
That left the test unable to observe the setItem call in CI even though the
per-session journal write was correct.

Select the native window.Storage prototype when available and otherwise spy
on the active localStorage object, preserving the assertion across both
storage implementations.

Subject: [PATCH 089/376] fix(desktop): skip stale journal duplicate folds

The inflight-turn journal can outlive the turn it recorded (reclaim,
reconnect or restart races skip the settle that clears it). On session
resume the fold then re-appends journaled assistant rows to a transcript
that already holds the committed replies, so the conversation ends with
duplicate answers in scrambled order. The fold also carried the stale
entry's streamId onto the resumed state on an idle resume, which kept the
journal entry alive (persistInFlightTurnState only clears when streamId is
null) and re-folded the same tail on every open.

Detect text-level staleness before the append path: when every recoverable
journaled assistant row already exists as committed text in the base
transcript, treat the entry as caught up and clear it. Only keep a stream
target when the resumed session is genuinely running (keepPending), so an
idle resume self-heals instead of re-folding.

Subject: [PATCH 090/376] fix(desktop): clear the stale stream target on the
 assistant-tail append path too

Sibling site of the idle-resume rule from the stale-fold fix: the
assistant-tail append exit (user row persisted, no projection row) still
carried the journal's streamId onto a not-running resume, which kept the
journal entry alive (persistInFlightTurnState only clears when streamId is
null) and re-folded the same tail on every open. Apply the same
keepPending gate and pin it with a regression assertion.

Subject: [PATCH 091/376] fix(memory): accept new_text as an alias for content
 (#86642)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

memory replace/remove target an entry by old_text but supply the replacement
via content — an asymmetric pairing. Callers naturally reach for new_text to
mirror old_text (it's exactly the patch tool's old_string/new_string shape),
which left content empty and errored 'content is required'. The failure also
rendered tersely, making the cause easy to miss and costing a retry.

Accept new_text as an alias for content on both shapes:
- single-op: coalesce content = content or new_text in memory_tool() + a
  new_text param wired through the registry handler.
- batch ops: content = op.content or op.new_text (and in the approval-gate
  preview builder).
- schema: document the alias on content and add a new_text property to the
  single-op params and batch item props so strict validators accept it.
content wins if both are set.

Tests: new_text alias on single add/replace, batch add/replace, and
content-wins-over-new_text. 43/43 across memory tool + schema suites.

Subject: [PATCH 092/376] fix(file-ops): skip per-file tsc when an ancestor
 tsconfig.json exists (#86640)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The post-write lint runs `npx tsc --noEmit <file>` on a single .ts file with
no `-p tsconfig`. tsc ignores tsconfig.json for explicit file args, so for any
file in a real TS project it floods phantom diagnostics — unresolved path
aliases (@/... -> TS2307) and ambient globals (Window.hermesDesktop -> TS2339)
that the project config defines. The delta filter sees the same phantom errors
pre- and post-edit, finds no NEW ones, and returns the misleading
'pre-existing lint errors ... the file is still broken' on a perfectly correct
one-line edit — wasting the caller's turns chasing nonexistent breakage.

Existing code already skips shell tsc when an LSP server claims the file, but
that only fires with LSP configured+enabled (not the default), leaving the
common LSP-disabled case fully exposed.

Fix: when an ancestor tsconfig.json exists (local host only), skip the per-file
shell tsc for .ts — its verdict carries zero signal for project files. Real
diagnostics still come from the LSP tier or an explicit `tsc -p tsconfig.json`.
Best-effort ancestor walk; remote/sandbox backends fall back to running the
linter as before. (.tsx already returns skipped via the ext-not-in-LINTERS
branch.)

Tests: ancestor-tsconfig .ts -> skipped even with LSP off; standalone .ts with
no ancestor tsconfig -> shell tsc still runs. 7/7 in the LSP-skip suite.

Subject: [PATCH 093/376] feat(delegation): mark max_iterations-truncated
 subagent results for the parent (#86641)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A delegated subagent that exhausts its per-child iteration budget
(delegation.max_iterations) still returns a summary, so the result carries
status='completed' even though the child's exit_reason is 'max_iterations' and
its work was cut off mid-task. The parent then reads 'completed', trusts the
partial summary, and only discovers the truncation by parsing the prose (where
the child happens to mention 'hit the iteration limit'). That wastes parent
turns and risks acting on incomplete work.

exit_reason is already computed authoritatively and threaded to every
parent-visible surface; it just wasn't reflected anywhere the parent reads at a
glance. This surfaces it:

- delegate_tool.py: add a parent-visible boolean 'truncated' (= exit_reason ==
  'max_iterations') to each task entry, alongside the existing exit_reason.
- process_registry._format_async_delegation: for both the batch and single-task
  paths, when truncated -> use a warning icon, append
  'TRUNCATED: hit max_iterations — work may be incomplete' to the header/Status
  line, and prefix the summary with an unmissable truncation notice. status
  semantics are left unchanged (stays 'completed') so existing icon/summary
  branch logic and ~10 tests asserting status=='completed' stay valid.

Tests: single-task truncated -> banner; single-task clean -> no banner; batch
marks only the truncated task, not its clean sibling. 23/23 in the async-
delegation suite.

Subject: [PATCH 094/376] fix(agent): bound hung inline API calls when abort
 cannot kill the socket
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The keepalive httpx client uses read=None, and stranger-thread abort cannot close FDs, so a DeepSeek stall on the cron inline path waited until TCP died — hours past the 600s watchdog. Inject a per-call read timeout matching the stale budget, walk in-flight pool requests, and clear the socket timeout before shutdown without releasing the FD.

Subject: [PATCH 096/376] fix(tools): refresh activity heartbeat while a tool
 call is in flight (#84491)

The gateway turn-inactivity watchdog (gateway/run.py::_watch_gateway_turn_inactivity)
abandons a turn once seconds_since_activity exceeds the inactivity timeout
(default 30 min). Activity was only stamped when a tool started and when it
completed, so a tool call that runs silently for 30+ minutes (quiet builds,
long pytest suites, large downloads, network waits with no output) froze the
clock and the watchdog hard-abandoned a turn that was still making progress,
reaping the tool's processes mid-execution (issue #84491).

Add a daemon-thread heartbeat inside _run_agent_tool_execution_middleware that
touches agent._touch_activity every 30s while the tool is in flight, until the
call returns. Both the sequential and concurrent execution paths funnel through
this single middleware, so one heartbeat covers every tool. The thread is
stopped in a try/finally so it always tears down even if execute() raises, and
is never started when a guardrail/authorization block short-circuits before
dispatch. A genuinely hung tool remains bounded by the tool layer's own
timeouts (terminal default 180s, concurrent batch deadline ~420s), so the
heartbeat only extends the turn's life while the call is legitimately running.

Verified by an independent reviewer (no security/logic defects); 5 unit/integration
tests pass on Python 3.12 (upstream CI). The 30-min gateway backstop remains
for turns whose agent loop itself stalls.

Subject: [PATCH 098/376] fix(ui-tui/ink): don't skip a zero-height box that
 hosts absolute children
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Opening any floating panel in the TUI (`/resume`, `/sessions`, `/models`,
`/skills`, …) with an ambient dock widget loaded shows nothing: the overlay
takes input (Esc is the only way out) but never paints. Part of #69592.

`renderNodeToOutput` has a ghost guard for boxes Yoga squeezes to h=0 whose
sibling lands on the same row — without it, the shorter content leaves the
longer one's tail on screen. The guard returns before rendering children.

The composer's floating panels are `position: absolute; bottom: 100%`
children of a relative Box that also holds the input rows. Opening a panel
sets `$isBlocked`, which unmounts those rows, so the host collapses to h=0
with a sibling on its row — and the guard drops the whole subtree, overlay
included.

An absolute child paints outside its host's layout bounds, so it never
writes the shared row and cannot ghost it. Skip only when the subtree has
no absolute descendant. The walk runs solely inside the h=0 branch, which
is already rare, so it stays off the hot path.

Gateway /new ends the predecessor with session_reset and leaves the child

Subject: [PATCH 100/376] test(session-search): cover /new-reset discovery,
 scroll, and browse

Regress the #85756 chain: a session_reset parent must surface from the
empty child, title/scroll must follow, browse must list that parent, and
live delegation children must stay hidden.

Subject: [PATCH 104/376] fix(gateway): cancel native clarify only on free
 prose
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Teknium review on #75732: releasing the pending clarify whenever
resolve_text_response_for_session returned False also cancelled
retryable multi-select invalid selections (out-of-range numbers,
unrecognised comma-lists).

Classify rejected typed replies in clarify_gateway:
- rejected_prose → cancel clarify, fall through busy routing (deadlock break)
- rejected_selection → keep clarify armed so the user can retry

Add native multi-select gateway regressions for both paths.

Subject: [PATCH 106/376] fix(gateway): route delivery-ledger owner-liveness
 probe through _pid_exists (#41662)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The `_owner_alive` fallback in gateway/delivery_ledger.py (taken whenever a
process start time is unreadable) probed liveness with a raw
`os.kill(pid, 0)`. On Windows that is NOT a no-op: CPython maps sig=0 to
`GenerateConsoleCtrlEvent(0, pid)` (bpo-14484), so probing a LIVE pid whose
start time psutil could not read would Ctrl+C the target's entire console
group. The prior `# windows-footgun: ok` annotation only justified the
EPERM-means-alive exception semantics, not the Ctrl+C side effect.

Route the probe through `gateway.status._pid_exists` (psutil-first,
ctypes OpenProcess fallback on Windows), preserving EPERM-means-alive.
A POSIX-only raw-probe fallback remains for the unreachable case where
gateway.status cannot be imported; on Windows that path reports dead
rather than firing a sig-0 probe.

Tests patch `gateway.status._pid_exists` per the windows-native-support
pattern, including a regression guard asserting os.kill is never used
for the probe. Sabotage-verified (revert → red, restore → green).

Part of #41662 (the os.kill half; watchdog half tracked separately).

Subject: [PATCH 107/376] fix(sanitize): drop tool_calls key when dedup removes
 all calls

The dedup pass in sanitize_api_messages (introduced by #58327) can
produce an empty tool_calls array when all tool_call_ids in a message
are duplicates of earlier messages in a long conversation history.

DeepSeek v4 and newer OpenAI reject empty tool_calls with HTTP 400:
'Invalid messages[N].tool_calls: empty array'.

When kept_tcs is empty after dedup, drop the tool_calls key entirely
instead of writing tool_calls: [].

Fixes #64335

Subject: [PATCH 109/376] fix(transport): strip empty/null tool_calls on
 assistant messages

Strict OpenAI-compatible providers (onerouter / Qwen, DeepSeek v4) reject
an assistant message carrying tool_calls: [] (or null) with HTTP 400
'Empty tool_calls is not supported in message.'

The pre-API sanitizer in agent_runtime_helpers.sanitize_api_messages already
drops these on the conversation_loop path, but auxiliary / custom-provider
routes that bypass that sanitizer can still reach the wire with an invalid
empty array and abort the whole session (non-retryable 400).

Normalize at the transport layer too: detect an empty-list / null
tool_calls on assistant messages, strip the key on the per-call copy (never
mutate the stored history), and keep real tool_calls untouched. Includes
unit tests covering empty-list, null, real-call preservation, mixed batches,
user-role non-mutation, copy-on-write, and cross-provider parity.

Follow-up to #58755.

Subject: [PATCH 113/376] fix(anthropic): coerce blank system text blocks at
 extraction (#70909)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Residual from PR #70910 after #77509 landed the message-list scrub: a
whitespace-only system content block carrying a cache_control marker
still reached the wire and 400'd the whole request ("text content
blocks must contain non-whitespace text"), wedging the session on every
retry. The block cannot be dropped (it carries the cache breakpoint),
so coerce its text to the shared non-whitespace placeholder when
extracting the system param, copying the block so caller message dicts
are never mutated.

Adds SHL0MS's request-level regression suite from #70910; four of its
five cases already pass on main via #77509 — the system-block case
fails without this fix.

Subject: [PATCH 115/376] fix(win): never rewrite the in-use managed Node tree
 (#80926)

The Hermes-managed Node tree at %HERMES_HOME%\node is destructively
rewritten while the desktop app's Node processes execute from it:
the Node-26 heal did shutil.rmtree + move, the EBADENGINE repair ran
npm install --global --prefix into the tree, and install.ps1's
Test-Node did Remove-Item + Move-Item. Windows rejects those writes
with PermissionError: [WinError 5] on npm.cmd.

- _heal_managed_node_windows: stage the fully-downloaded tree in a
  sibling node.new-* dir, then rename-swap (live tree -> node.old-*,
  staged -> node). The live tree is never deleted before its
  replacement is ready, so an interrupted heal cannot gut it; a
  refused rename is the OS-level in-use signal and defers (returns
  None) instead of forcing the write.
- heal_hermes_managed_node: an in-use deferral does not record the
  once-per-process attempt, so the heal retries once the tree is free.
- managed_node_tree_in_use: cheap psutil pre-check (Windows only) that
  avoids pointless 30-50MB re-downloads in long-lived processes.
- upgrade_managed_npm: defer the in-place npm self-upgrade while the
  tree is in use, with a notice.
- install.ps1: Test-ManagedNodeInUse guard around Update-ManagedNpm and
  the Test-Node install branch, which now rename-swaps instead of
  delete-then-move.

An in-use-but-outdated tree keeps serving the old runnable Node (old
Node beats no Node), and every npm resolution re-evaluates the heal, so
the upgrade applies automatically on the next update with the app
closed.

Subject: [PATCH 116/376] fix(win): CIM-based PS in-use check and same-volume
 staging swap
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adopts two improvements from #81586 (kshitijk4poor), with one correction:

- Test-ManagedNodeInUse now queries Win32_Process (ExecutablePath +
  CommandLine substring) instead of Get-Process .Path: a cmd.exe wrapper
  running npm.cmd from the tree reports its own exe in System32, so the
  tree path shows up only in the command line. Win32_Process.CommandLine
  works on Windows PowerShell 5.1 and 7+, unlike the Get-Process
  .CommandLine ETS property (7.4+ only); a single CIM query also beats a
  per-process property access loop. This closes the gap flagged by the
  triage bot on #81500 (Update-ManagedNpm's only in-use protection is
  this pre-check).
- Test-Node stages the extracted tree to a sibling node.new-* before the
  swap, so the final swap is a same-volume rename (atomic) instead of a
  cross-volume Move-Item (copy+delete, non-atomic).

The mtime-touch ordering from #81586 was NOT adopted: touching the backup
only after the swap succeeds leaves it at its old (long-lived-tree) mtime
for the whole swap window, which the age-gated litter sweep (st_mtime <
cutoff) removes — reopening the concurrent-sweep race the touch exists to
close. The touch stays immediately after the backup rename.

Subject: [PATCH 117/376] test: pin Test-Node managed-Node swap to
 same-directory renames

The Test-Node stage-and-swap relies on Rename-Item's same-directory
carve-out: -NewName accepts a path only when it shares the directory of
-Path (FileSystemProvider strips the directory and keeps the leaf), and
all four swap calls rename between $HermesHome\node and sibling
node.new-* / node.old-* paths. Pin that invariant so a future refactor
cannot introduce a cross-directory rename, which would throw on every
Windows install and read as a false "in use" deferral.

Source-level probe, matching the other tests/test_install_ps1_*.py
regressions (Linux CI cannot execute the Windows installer).

+"""Regression: the Test-Node managed-Node stage-and-swap must stay same-directory.
+
+Review concern on #81500: ``Rename-Item`` rejects a path in ``-NewName`` --
+with one carve-out. PowerShell's FileSystemProvider strips the directory and
+keeps the leaf when the ``-NewName`` path shares the directory of ``-Path``
+(``FileSystemProvider.RenameItem``: ``Path.GetDirectoryName(path) ==
+Path.GetDirectoryName(newName)`` -> ``newName = Path.GetFileName(newName)``);
+only a path that *differs in directory* throws "represents a path or device
+name". The official docs state the same exception ("you can't supply a path
+for the value of the NewName parameter, unless the path is identical to the
+path specified in the Path parameter").
+
+The swap in ``Test-Node`` relies on exactly that carve-out: it renames
+between ``$HermesHome\node`` and sibling ``node.new-*`` / ``node.old-*``
+paths (same directory, same volume -- atomic rename). This test pins the
+invariant so a future refactor cannot silently introduce a cross-directory
+rename, which would throw on every Windows install and read as a false
+"in use" deferral.
+
+Source-level because Linux CI cannot execute the Windows installer (same
+rationale as the other ``tests/test_install_ps1_*.py`` probes).

Subject: [PATCH 118/376] fix(sessions): run state.db schema migration eagerly
 at backend startup and stop swallowing locked ALTERs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After `hermes update`, an existing state.db on an old schema made every
GET /api/sessions poll fail with sqlite3.OperationalError "no such
column: s.last_read_at" (or s.last_activity_at) until something
unrelated forced a writable open — the desktop sidebar showed "No
sessions yet" while every row sat intact on disk (#79531, #80037).

Two remaining root causes (the stale hand-written read probe was
already replaced by the SCHEMA_SQL-derived probe on main, prototyped in
draft PR #80030 by @Tilly-YL):

1. Migrations ran lazily: _init_schema/_reconcile_columns only ran on a
   writable open, typically the user's first NEW session. The dashboard
   backend now schedules one writable open of its own state.db from the
   lifespan (daemon thread, never blocks the ready-probe socket, never
   raises), so the store is brought current before the first session-
   list poll on every `hermes serve` / `hermes dashboard` / Desktop
   headless entrypoint.

2. _reconcile_columns caught sqlite3.OperationalError around every
   ALTER TABLE ADD COLUMN and logged at DEBUG. Lock contention from
   orphaned sibling backends made the ALTER fail silently — startup
   "succeeded" with a half-reconciled schema, and the open-time lock
   patience (#74478) never saw the error because it was swallowed
   inside first. Now: "duplicate column" races stay at DEBUG,
   locked/busy re-raises so _connect_and_init_with_lock_patience
   retries the whole idempotent init with jittered backoff, and any
   other failure (e.g. un-ADDable NOT NULL) logs at WARNING.

Regression tests: a store missing sessions.last_read_at is healed by
the eager startup reconcile and serves list_sessions_rich; a locked
ALTER propagates and is retried to success by the open lock patience;
duplicate-column races stay quiet; other ALTER failures warn.

Fixes #79531
Fixes #80037

Reported-by: @yenhunghuang (#79531) and @FLOW3R0111 (#80037)
Root-cause analysis: @wangyi0177-eng (stale read probe) and
@www654cc-pixel (_reconcile_columns DEBUG-swallow under lock
contention); draft PR #80030 by @Tilly-YL prototyped the probe fix.

Subject: [PATCH 119/376] fix(agent): preserve MoA facade when rebuilding
 primary client (stream retry, rotation, fallback+restore)

When agent.provider == "moa", the MoAClient facade *is* the client - there is
no real OpenAI wire endpoint behind the moa://local placeholder. Client rebuilds
(_replace_primary_openai_client: stream-retry pool cleanup, credential rotation,
dead-connection cleanup, fallback+restore) go through create_openai_client and
produce a native OpenAI client while provider stays "moa". The next primary
call then either raises a `_moa_prepared_request` TypeError (#78382) or, when
_client_kwargs carry an unrelated relay base_url, leaks the request to a foreign
gateway (observed as HTTP 503 "group ... no available channel" from an
unrelated new-api relay right after an aggregator empty-stream retry).

Fix: in create_openai_client, when provider is "moa", return
build_moa_facade(agent, model) instead of a native client. This covers every
rebuild entry point. The three already-fixed call sites
(restore_primary_runtime, try_recover_primary_transport, switch_model) assign
the facade directly and do not go through create_openai_client, so they are
unaffected.

Closes #78382

Subject: [PATCH 120/376] fix(agent): stop the MoA prepared request reaching a
 swapped-in native client

`_moa_prepared_request` is a private handshake between the conversation
loop and MoAChatCompletions.create. It is attached whenever
agent.provider == "moa", on the assumption that agent.client is still the
in-process MoA facade.

Credential rotation, provider fallback and dead-connection cleanup all
rebuild agent.client from _client_kwargs between attempts, and
pending_moa_prepared_request deliberately carries a prepared request
across exactly that boundary. The rebuilt client is a native OpenAI
client while provider stays "moa", so the key reaches an SDK that has
never heard of it:

    TypeError: Completions.create() got an unexpected keyword argument
    '_moa_prepared_request'

That error is non-retryable, so every remaining turn on the session
fails. Both dispatch paths are affected: the non-streaming one calls
agent.client directly, and _create_request_openai_client returns
agent.client unchanged for provider "moa".

Re-check the live client at the point the key is attached, which covers
both paths at once. When the facade is gone, send the prepared prompt
without the handshake and log the downgrade.

Subject: [PATCH 121/376] fix(agent): strip _moa_prepared_request before
 dispatching to native client

After a client replacement (credential rotation, dead-connection cleanup,
or fallback+restore), agent.client may become a native OpenAI client
while agent.provider stays "moa".  The _moa_prepared_request key was
passed through to the native SDK, causing TypeError on every turn.

Pop the key at the dispatch point (chat_completion_helpers.py:509).
The MoAClient facade already handles a missing key by falling through
to its normal resolution path.

Closes #78382

Subject: [PATCH 123/376] fix(agent): only strip _moa_prepared_request when the
 live client is not the MoA facade
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The unconditional pop from the previous commit also stripped the key when
agent.client was still the real MoA facade, forcing the facade to re-prepare
from scratch — a duplicate reference fan-out per turn (caught by
test_moa_virtual_provider_aggregator_is_actor). Gate the defensive strip on
the same prepare()-capability probe used at the injection site so the
handshake survives on the facade while a swapped-in native client is still
protected.

Subject: [PATCH 125/376] fix(desktop): resolve react/react-dom from one origin
 (#84018)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The desktop window opened blank white on a fresh install: React threw
"Minified React error #527" before the first paint, from the
`vendor-react-<hash>.js` chunk.

`apps/desktop` pins react and react-dom to the same exact version, but
`vite.config.ts` aliased both to a hardcoded `../../node_modules/<pkg>` —
straight into the monorepo root, where npm is free to hoist a different
react. `@streamdown/math` is a root dependency whose react peer is
`^18.0.0 || ^19.0.0` and which declares no react-dom peer, so npm hoists
the newest react (19.2.8) to the root while react-dom stays at the
version hoisted from the workspaces (19.2.7). react-dom's own peer is
`react: ^19.2.7`, which 19.2.8 satisfies, so the install reports success
and nothing warns. The bundle then shipped react 19.2.8 with react-dom
19.2.7 and React refused to run.

`npm ci` masks this because the lockfile pins the root react to 19.2.7,
which is why CI is green. The recurrence engine is
`_run_npm_install_deterministic()`: when `npm ci` fails it falls back to
`npm install --no-save`, which re-resolves the whole tree and never
records the result — so the split comes back on the next update and
leaves no trace.

Fix the resolution rather than the hoist. The aliases now resolve both
packages from the desktop workspace itself, where npm guarantees the
declared versions are reachable (it nests a copy under the workspace
exactly when the hoisted one differs), so the pair can only ever match.
Pinning react at the npm layer instead was rejected: every manifest-level
pin tried (root dependency, root `overrides`, a scoped override on
`@streamdown/math`) breaks a fresh install with
`ERESOLVE ... peer ink-text-input@"6.0.0" from @hermes/ink@0.0.1`.

Two guards keep it from silently returning:

- `assert-root-install.mjs` (the existing preflight of `build`,
  `dev:renderer` and `preview`) now fails the build when the resolved
  react and react-dom versions differ, so a split surfaces as an
  actionable error instead of a white window.
- A `tests-js` contract test asserts every workspace pins the two to the
  same exact version, and that the desktop bundler no longer points at a
  hardcoded `node_modules` path.

Verified on a synthetic split tree (root react 19.2.8 / react-dom 19.2.7,
workspace react 19.2.7): the old aliases resolve 19.2.8 + 19.2.7, the new
ones resolve 19.2.7 + 19.2.7, and the preflight exits 1 when the
workspace itself resolves the mismatch.

Subject: [PATCH 126/376] fix(gateway): close leaked poller sockets in
 weixin/email adapters (#79889)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

On macOS (256 soft fd limit), routing the weixin/email pollers through a
local HTTP proxy leaked one TCP socket per failed poll/connect cycle
until the gateway hit `[Errno 24] Too many open files` and crashed
(launchd respawn loop). Live capture showed 216 of 256 fds pinned on
connections to the proxy, ~214 of them abandoned.

Code-side gaps fixed:

- email adapter, `connect()`: no try/finally around the IMAP test
  connection — a failure in login/ID/select/search abandoned the
  connected socket with no owner. Every reconnect-watcher retry builds
  a fresh adapter, so each retry against an unreachable/proxied host
  leaked another fd. Teardown now runs in `finally`.
- email adapter, IMAP teardown: `imaplib.IMAP4.logout()` only swallows
  `OSError` internally; on a broken connection `LOGOUT` raises
  `IMAP4.abort` before the internal `shutdown()`, leaving the socket
  open. New `_close_imap()` helper chases a failed `logout()` with an
  unconditional `shutdown()`; used in `connect()` and
  `_fetch_new_messages()`.
- weixin adapter: repeated poll failures through a proxy strand
  sockets in the aiohttp connector where the tight keepalive reaper
  never sees them. The poll loop now recycles its ClientSession
  (swap-then-close, safe for concurrent `_process_message` tasks)
  after each MAX_CONSECUTIVE_FAILURES streak, tearing down the
  connector and every socket it holds.

Targeted tests: tests/gateway/test_poller_fd_lifecycle.py (9 tests).

Reported by @EthanHunter1229 with measured fd captures.

Subject: [PATCH 127/376] fix(delegate): subagents get a dedicated SessionDB,
 not the parent's (#81267)

Cron run_job closes its per-job SessionDB in its finally block while a
fire-and-forget background delegation subagent is still flushing on a
daemon thread. The child shared the parent's SessionDB object, so every
subsequent flush hit the closed handle ('NoneType' object has no
attribute 'execute') and the child's whole transcript was silently
dropped. The same teardown-while-child-alive shape exists on gateway
session end and /new mid-delegation.

Each child now opens its own SessionDB connection (owned flag set at
construction so child.close() releases it), so no parent teardown can
close the child's handle out from under it.

Regression test proves the child gets a distinct live handle that
survives the parent's close().

Subject: [PATCH 128/376] fix(delegate): close the dedicated SessionDB if child
 construction fails; test degradation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Review follow-up (cc3f18197): if AIAgent() raises inside _build_child_agent
the freshly-opened dedicated handle has no owner and no child close() will
ever run — release it on the exception path so the sqlite fds don't
outlive the failed spawn. Also pin the degradation contract with a test:
a parent without a SessionDB still yields session_db=None children.

Subject: [PATCH 129/376] fix(delegate): child's dedicated SessionDB must
 follow the parent's db_path
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A bare SessionDB() resolves the launch profile's default state.db, but
parents can hold non-default per-profile handles (tui_gateway opens
SessionDB(db_path=<profile_home>/state.db) for non-launch profiles and
hands them to agents via _transfer_db_to_agent). A child of such a
parent would write its transcript into the WRONG database — cross-
profile leakage that breaks parent_session_id lineage and
session_search. Open the dedicated handle at the parent handle's
db_path instead (AsyncSessionDB forwards .db_path via __getattr__, so
the gateway wrapper path works too). Regression test verified RED on
the pre-fix code.

Subject: [PATCH 130/376] fix(compression): adopt live continuation tip at
 flush across multi-hop chains

A turn writing against a session already closed by compression died with
session_persistence_failed and a misleading "this is often a full disk"
dialog, even though the store was healthy and a live continuation existed
(#82001). Depth-1 recovery (find_live_compression_child) could not resolve
lineages with >=2 compression hops (root -> mid -> tip), reproduced
independently on two- and three-hop chains.

- run_agent.py flush chokepoint: on CompressionSessionClosedError, resolve
  tip = db.get_compression_tip(old_id) (canonical bounded transitive walk),
  adopt only when tip != old_id AND the tip row is live, retry the flush
  exactly once (adoption budget); otherwise fail closed.
- gateway/session.py append_to_transcript: replace the depth-1 live-child
  lookup with the same tip + liveness contract, so gateway transcript
  reroutes follow full chains.
- agent/conversation_compression.py _adopt_live_compression_child: turn-start
  recovery preflight now resolves via get_compression_tip with the same
  liveness check, closing the last depth-1 consumer in this family.
- classify_persistence_error: new "compression_closed" bucket; the turn-end
  explanation names compression rotation and tells the client to refresh the
  session id instead of blaming a full disk.

Tests: depth-1 adoption, multi-hop chain adoption (agent + gateway), fail
closed with no continuation / stale-closed (ws_orphan_reap) tip, exactly-once
adoption budget, and error-wording guards (compression-closed never mentions
disk; real disk failures keep disk guidance).

Closes #82001

Subject: [PATCH 131/376] fix: close leaked SessionDB connections on /insights
 and sessions-repair exception paths (#83226)

Two call sites create SessionDB instances without closing them on error:

1. gateway/slash_commands.py: /insights command - db.close() was on the
   success path but not in a finally block, so exceptions between
   SessionDB() and db.close() leak the connection.

2. hermes_cli/sessions_cmd.py: sessions repair - SessionDB() created
   inline with no .close() at all, leaking the FD on every call.

Salvage note: the original PR (#83237) also added a __del__ safety-net
finalizer to SessionDB; review showed the atexit hook registered by
queue_token_counts() strongly retains the instance, so the finalizer never
fires for the leak class it claimed to cover. Dropped here in favor of the
deterministic constructor-finally ownership repair salvaged from #83620.

Subject: [PATCH 132/376] fix(state): close leaked SessionDB connections on
 exception paths (#83226)

SessionDB could leave native SQLite handles open when construction failed
partway through schema/pragma/FTS/repair/lock/interrupt handling. Other
short-lived callers (MCP reads/polling, session search, reactions, trace
upload, insights, shutdown recovery) opened temporary SessionDB handles
without a complete ownership boundary. API-server profile caches and
RetainDB shutdown had similar late-close races. Under sustained load this
exhausted file descriptors (EMFILE).

- Close partially initialized SessionDB connections on every constructor
  exception path via a finally block guarded by an initialization-complete
  flag.
- Close temporary/cross-profile SessionDB handles in finally blocks across
  CLI, MCP, search, trace, reactions, insights, and recovery paths.
- Add API-server per-profile cache ownership and disconnect cleanup.
- Make RetainDB writer-queue shutdown exception-safe: track connections per
  thread, close on worker exit, reject new enqueues after shutdown starts,
  and sweep any connections left by short-lived threads.
- Add regression coverage for constructor failures, worker-thread readers,
  API disconnect failures, shutdown recovery, RetainDB late enqueue, and
  foreign-loop async clients.

Salvage notes: the original PR's per-thread WAL-reader ownership changes
were superseded by main's read-connection pool (permits + checkout/return);
its cron timeout-abandon fix is credited separately to #72822's earlier
identical fix.

Subject: [PATCH 133/376] fix(cron): close leaked SessionDB connection when
 init outlives the timeout-abandoned worker (#72782)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

run_job() submits SessionDB() to a one-worker executor and abandons the
worker (shutdown(wait=False)) when init exceeds the cron timeout. If the
constructor later completes inside that abandoned worker, the Future's
result — an open SessionDB holding .db/WAL/SHM handles — was orphaned and
never closed, leaking descriptors until EMFILE. Attach a done-callback on
the timeout path that retrieves and closes any eventual late result.

Salvage note: the lazy-recall ownership half of #72822 (_owns_session_db
tracked on AIAgent, owned handle closed in close()) already landed on main;
this carries the remaining cron timeout-abandon half with its regression
test.

Subject: [PATCH 134/376] test: fix salvage test imports; drop WAL
 worker-thread test superseded by read pool
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- tests/cron/test_sessiondb_init_hang.py: add threading/time imports the
  salvaged late-close regression tests rely on.
- tests/test_hermes_state.py: drop
  test_close_closes_wal_read_connection_created_on_worker_thread — main
  replaced per-thread WAL reader ownership with the pooled read-connection
  design (permits + checkout/return), so cross-thread reader draining no
  longer exists in the form the test asserted.

Subject: [PATCH 136/376] fix(gateway): exclude service-managed PIDs from
 orphan reaping
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

_reap_unsupervised_gateway_orphans() kills every gateway PID found by
find_gateway_pids() on hosts without systemd (macOS launchd, Windows
Scheduled Task). This includes service-managed gateways that are NOT
orphans — they are supervised by launchd/systemd and should never be
killed during a stale-process sweep.

Add own |= _get_service_pids() to the exclusion set before scanning,
so launchd/systemd-supervised gateways are preserved. True orphans
(reparented leftovers not present in launchctl/systemctl) are still
found and reaped, preserving the #77276 protection.

Fixes #85344 (macOS launchd gateway killed by desktop serve startup)
Fixes #85044 (Windows Scheduled Task gateway killed by desktop serve)
Fixes #84855 (Permission denied to kill orphaned gateway PID)
Fixes #85368 (gateway process repeatedly killed, messaging offline)

Subject: [PATCH 137/376] fix(gateway): spare Scheduled-Task-supervised gateway
 from orphan reaper on Windows
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The orphan reaper kills a healthy gateway (and its Scheduled-Task bootstrap
parent chain) every time the Desktop backend starts on Windows, because
_get_service_pids() only implements systemd/launchd and returns an empty
set on Windows — a supervised gateway is therefore indistinguishable from
an unsupervised orphan.

Exempt the recorded healthy gateway PID and its parent chain from the
orphan scan on Windows, mirroring the macOS launchd exemption (#85913).
The Scheduled-Task bootstrap's argv matches the gateway scan, so without
exempting the parent chain killing the bootstrap takes the detached
gateway down with it.

Fixes #86098

Subject: [PATCH 138/376] fix(gateway): generalize supervised-gateway exemption
 in orphan reaper to all platforms
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Compose the service-PID exclusion (#85743, RelaxJonh) and the recorded-PID +
parent-chain exemption (#86100, arccat-114) into one cross-platform rule:

- _get_service_pids() exclusion now runs unconditionally, not only under
  is_macos() — it is the authoritative "supervised" signal for launchd and
  any systemd unit visible on a host that got past the systemd gate.
- The recorded-healthy-gateway (get_running_pid()) + parent-chain exemption
  now runs on every platform, not only Windows. A recorded, liveness-verified
  gateway is by definition not an orphan "the pidfile/runtime record can't
  see", so the reaper must never target it — this covers Windows Scheduled
  Task / Startup VBS supervision, standalone launcher-started gateways
  (the case #85743 alone would miss), and macOS/WSL equivalents.

True orphans (no service registration, no valid runtime record) are still
found and reaped, preserving the #51325/#75936 duplicate-port protection.

Existing macOS regression tests updated to pin get_running_pid to None for
their scenario; Windows regression tests from #86100 carry over unchanged.

Bug class: #83683 (root), #86287, #86098, #85738, #85368, #85344, #85044,
#84855, #84824, #84200.

 serve --port 0 (#78821)

Filter manual dashboard/serve respawn candidates after update: skip
ephemeral --port 0 backends (Desktop-owned), dedupe normalized cmdlines,
and cap one restart per profile/HERMES_HOME so orphan counts no longer
grow across successive updates.

Subject: [PATCH 142/376] fix(gateway): give in-flight cron work its own drain
 floor
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`agent.restart_drain_timeout` defaults to 0 and governed every class of
in-flight work at once. That default is deliberate for chat turns: the
gateway announces the restart to the user and pre-marks the session
resume_pending, so interrupting one is cheap and recoverable.

A cron run has neither property. Nobody is waiting on it, it is written
to jobs.json as a permanent failure, and a recurring job simply skips to
its next schedule. Sharing the chat budget meant `_drain_active_agents()`
short-circuited on `timeout <= 0` before entering the wait loop, so the
drain reported `drain took 0.00s, timed_out=True, cron_at_start=1,
cron_now=1` — it detected the job and killed it anyway.

Cron work now drains on its own deadline, `agent.cron_drain_timeout`
(default 30s, 0 opts out). The floor is clamped to the shutdown-watchdog
leash minus a teardown reserve, so the longer wait can never consume the
post-drain cleanup window: being SIGKILLed mid-cleanup would leave the
job wedged at `last_status=running`, strictly worse than the bug. Being
bounded also means a cron-triggered restart cannot deadlock on itself.

The `timeout <= 0` special case is gone — an expired deadline expresses
the legacy "interrupt immediately" behaviour, so `timed_out` is always
computed from real state instead of asserted up front. The drain-timeout
warning now reports the elapsed wait rather than the configured budget,
which is what made "timed out after 0.0s" so confusing in the report.

Chat-only shutdowns are unchanged: `restart_drain_timeout: 0` still
interrupts chat turns immediately.

Relates to #82161 (complements #82195, which removes the `hermes update`
self-deadlock that triggered the reported instance).

+budget to every class of in-flight work. That default is deliberate for chat
+turns — the user is told the gateway is restarting and the session is
+pre-marked resume_pending, so interrupting one is cheap and recoverable — but
+a cron run has neither property: it is written to jobs.json as a permanent
+failure that nobody is waiting on, and a recurring job just skips to its next
+schedule.
+
+With the shared budget the drain short-circuited on ``timeout <= 0`` before
+the wait loop, producing the reported log line: ``drain took 0.00s,
+timed_out=True, cron_at_start=1, cron_now=1`` — it detected the job and killed
+it anyway. Cron work now drains on its own floor (``cron_drain_timeout``),
+clamped to the shutdown-watchdog leash so the extra wait can never eat the

Subject: [PATCH 143/376] fix(gateway): keep the cron drain floor compatible
 with shutdown test doubles
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

CI slice 5/12 caught two ways the new cron budget broke `_stop_impl_body`
for callers that are not real GatewayRunner instances:

- `_FakeGateway` in test_shutdown_cache_cleanup.py borrows `_stop_impl`
  without subclassing, so it never picked up the class-level
  `_cron_drain_timeout` default and raised AttributeError. Read it through
  the getattr-guard convention the same function already uses for its
  liveness-guard machinery.
- The same double overrides `_drain_active_agents(self, timeout)`, so
  passing the cron budget raised "takes 2 positional arguments but 3 were
  given". The double now mirrors the real optional parameter. It is the
  only override in the tree; test_startup_restart_race.py uses AsyncMock,
  which accepts any signature.

Verified against a stashed clean tree: the 22 gateway test files that
still fail locally fail identically with and without this branch (80 = 80,
empty set difference both ways) — they are pre-existing Windows-only
failures (setsid, POSIX modes) unrelated to this change.

Subject: [PATCH 144/376] fix(gateway): deliver interrupted-cron notices before
 adapters disconnect
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When the shutdown drain times out and kills an in-flight cron job, the
job's owner is never told. The cron worker does try: `_is_interrupted()`
forces the failure path with an honest "interrupted by gateway shutdown"
error, and failed jobs always deliver. But that worker is a thread, it
reaches `_deliver_result()` asynchronously, and by then
`_bounded_adapter_teardown()` has closed the transport. The reporter of

Worse, the loss is silent twice over: `_consume_interrupted_flag()`
returns True — the gateway already wrote `last_status` — so
`mark_job_run()` is skipped, and the `delivery_error` from the failed
send is discarded with it. The run's only trace is a generic line in
jobs.json.

The gateway already owns the right window. `_notify_active_sessions_of_
shutdown()` runs while adapters are up, precisely so shutdown messages
can be sent — but it iterates `_running_agents`, and cron work lives on
the scheduler's own thread pool. Same structural blindness already fixed
for counting (#60432) and draining (#63529), never fixed for notifying.

So notify from the post-interrupt phase, which is the last point where
the transport is still up: `_kill_tool_subprocesses()` now returns the
job IDs it marked, and `_notify_interrupted_cron_jobs()` sends each one's
owner a notice on the job's own resolved delivery targets. Adapter
teardown order is untouched — it is load-bearing for #53175 and #8202.

Jobs with `deliver: local`, and `deliver: origin` jobs with no resolvable
origin (#43014), resolve to zero targets and stay silent. Per-platform
`gateway_restart_notification: false` is honoured, matching the chat
path. Every failure is swallowed so a wedged adapter cannot extend
shutdown.

Second, when the interrupted flag short-circuits `mark_job_run()`, the
delivery failure is now persisted on its own via `update_job()`, so a
notice that still cannot be sent is at least recorded. `update_job()`
rather than a second `mark_job_run()`: the latter also advances
`next_run_at` and the repeat counter, and running that twice for one run
would skip a fire or auto-delete the job early.

Fixes #82232. Related: #82161, #82224.

+"""Regression tests for #82232.
+
+When the shutdown interrupts an in-flight cron job, the job's own worker
+thread tries to deliver an "interrupted" notice — and loses, because
+``_bounded_adapter_teardown`` has already closed the transport by the time it
+gets there. The notice is dropped, and ``_consume_interrupted_flag`` discards
+the resulting ``delivery_error`` with it, so the run's only trace is a line in
+jobs.json.
+
+The gateway now sends that notice itself in the post-interrupt phase, while
+adapters are still connected — the same window
+``_notify_active_sessions_of_shutdown`` uses for chat sessions, which never
+saw cron work because cron runs outside ``_running_agents`` (#60432).

 their notices still send
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

mark_running_jobs_interrupted skipped legacy fires without a registered
durable owner entirely — correct for the persisted last_status write
(no owner fence to protect a replacement run), but the gateway shutdown
path also uses the returned ID list to deliver interrupted-cron notices
while adapters are still connected (#82232). Keep the persistence skip,
but include the job in the returned list so the user is still told.

Subject: [PATCH 146/376] fix(backup): restore import members atomically so a
 failed import can't erase config
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`hermes import` wrote every zip member with `open(target, "wb")` followed by
`dst.write(src.read())`, at both restore sites in `run_import`. Opening for
write truncates the user's existing file to zero *before* any replacement
bytes exist, so a Ctrl-C, an ENOSPC, a corrupt zip member, or a crash leaves
`config.yaml`, `.env`, or an external provider config (e.g.
`~/.honcho/config.json`) empty with nothing behind it — during the
disaster-recovery path the user is running precisely because they already
lost something. The `_external/` branch writes outside HERMES_HOME, into
third-party configs under the user's home, so the blast radius is not
confined to Hermes state.

Both sites now stage the member into the target's own directory, fsync it,
and publish with `utils.atomic_replace`, so the target only ever moves from
its old contents to the complete new contents.

`atomic_replace` rather than a bare `os.replace`: it resolves a symlinked
target first, so deployments that link `config.yaml` into a dotfiles repo
keep the link instead of having it silently swapped for a regular file
(#16743), and it falls back to copy/fsync/unlink on EXDEV/EBUSY for
cross-device and bind-mount installs. Members stream through
`shutil.copyfileobj` instead of being read whole into memory. The temp file
is removed on any failure so a partial import leaves no residue, and
permission bits are carried across the replace so mkstemp's 0600 does not
silently tighten restored files.

This extends the module's own established idiom — `backup.py` already
publishes atomically via `os.replace` in `_atomic_output_path` and in the
snapshot writer — into the one path that still overwrote user files in place.

From 1c3c1f4d71a004aad69666e048618e41cd7fe41a Mon Sep 17 00:00:00 2001
From: briandevans <252620095+briandevans@users.noreply.github.com>
Date: Thu, 6 Aug 2026 16:30:21 -0700
Subject: [PATCH 147/376] fix(backup): preserve owner on atomic import writes
 and close the 0600 transit window
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Follow-up on the atomic-import restore, delegating both metadata concerns to
the shared helpers instead of half-handling them locally.

Owner preservation was missing entirely. `tempfile.mkstemp` + `atomic_replace`
publishes a temp file owned by the *writing* user, so `sudo hermes import`
re-owned every restored file to root — on the disaster-recovery path, and on
exactly the Docker/NAS volume installs `utils._restore_file_owner` was added
for. `_extract_member_atomically` now captures `_preserve_file_owner(target)`
before staging and calls `_restore_file_owner` after the replace, before the
mode restore (chown clears setuid/setgid, so the mode has to go back last).

Mode handling was also only half applied before the replace: the `os.fchmod`
branch applied it to the temp fd, but the platforms without `fchmod` fell
through to a best-effort post-replace chmod, leaving the published file at
mkstemp's 0600 until that chmod landed — permanently if the process died in
between — and making `atomic_replace`'s EXDEV/EBUSY `shutil.copystat` fallback
copy 0600 onto the target. The mode is now applied to the temp file on both
branches, with the post-replace `_restore_file_mode` kept as the belt-and-
braces path.

This is the same shape `atomic_write_text` and `atomic_yaml_write` already
carry after 3556728a5 and 43fc86562; capture and restore now reuse
`utils._preserve_file_mode` / `_preserve_file_owner` / `_restore_file_mode` /
`_restore_file_owner` rather than re-deriving them, which also drops the local
`import stat`.

Tests (tests/hermes_cli/test_backup.py, class TestImportAtomicWrites):
- test_restore_preserves_existing_file_owner — forces a uid/gid so it does not
  need root; asserts chown fires once, with the captured owner, on the
  pre-existing file only (a newly created member has no prior owner).
  Mutation-checked: dropping only the `_restore_file_owner` call reds it.
- test_mode_is_applied_before_the_replace_without_fchmod — `monkeypatch.delattr`
  on `os.fchmod`, spies the temp file's mode at replace time. Reads 0o600
  without the fix, 0o644 with it. Mutation-checked the same way.

Subject: [PATCH 148/376] docs(backup): note that atomic_replace's cross-device
 fallback still truncates

The atomicity claim in _extract_member_atomically's docstring holds on the
os.replace path but not on atomic_replace's EXDEV/EBUSY fallback, which uses
shutil.copyfile and so opens the destination 'wb'. That is pre-existing
behaviour shared by every atomic writer in the repo, and it is reachable here
for a symlinked target whose real file lives on another filesystem. Scope the
docstring to what the helper actually guarantees instead of overstating it;
the fallback itself is a utils.atomic_replace change.

Subject: [PATCH 149/376] fix(backup): drop setuid/setgid from the mode
 restored onto imported files
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

``_extract_member_atomically`` carries the replaced file's permissions
across the publish so that routing through mkstemp does not change what
the caller would otherwise have produced. But ``_preserve_file_mode``
returns ``stat.S_IMODE``, which is all twelve bits, and this restore is
deliberate on both sides of the replace: the mode is fchmod'd onto the
temp before ``atomic_replace`` and re-applied afterwards because chown
clears the elevated bits. So a target sitting at 0o4755 comes out of
``hermes import`` still at 0o4755 — with contents supplied by the zip.

That is a regression introduced by the atomic rewrite rather than a
pre-existing one. The overwrite it replaced was an in-place
``open(target, "wb")``, and an in-place write by a process without
CAP_FSETID has the elevated bits stripped by the kernel, so the old path
left 0o4755 as 0o755.

The blast radius is not limited to Hermes' own state: the ``_external/``
branch of ``run_import`` publishes members anywhere under ``$HOME``, and
this is the path that documents ``sudo`` use so ownership survives a
restore. An archive that happens to contain a member matching some
existing privileged file would take over the identity that file runs as.

Mask the two bits off the preserved mode. The masking happens once,
before the temp file is chmod'd, so there is no transient elevation
either. The sticky bit is kept — it is inert on a regular file. The
ordinary permission bits are unaffected, so the Docker/NAS installs the
preservation exists for still get their broader modes back.

This is the one write path in the repo where the bytes are untrusted;
the ``utils`` writers that preserve the full mode re-serialize content
the process itself produced, and are correct as they stand.

Subject: [PATCH 150/376] test(backup): assert an imported member cannot keep a
 setuid target's bits
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Pre-creates a 0o6755 target, imports a member over it, and asserts the
published file is 0o755 with both elevated bits gone — plus that the
staged temp file never carried them either, so there is no window where
archive content sits behind an elevated mode.

The existing coverage in this class cannot see the failure: every mode
assertion masks with ``& 0o777``, which discards exactly the bits at
issue, and the fixtures chmod their targets to ordinary modes that never
had them set. Without the mask on the preserved mode this test reports
the published file still holding S_ISUID.

Skipped where the platform or filesystem refuses setuid on a user-owned
file, so the assertion never depends on running as root.

Subject: [PATCH 152/376] fix(desktop-update): make posix hand-off survive
 Electron quit teardown (macOS)

The Desktop-spawned hand-off consistently died during Electron's quit
teardown on macOS: the orchestrator process group was terminated right
after `running: hermes update ...`, so no exit code, result file, bundle
swap, or relaunch ever happened, and the loopback shim window surfaced
the death as ERR_CONNECTION_REFUSED or "Aw, Snap!" error code 15
(reproductions in #66753).

- Re-exec the orchestrator through a one-shot setsid child and let the
  direct Electron child exit immediately; the real orchestrator is owned
  by launchd (PPID 1), outside Electron's teardown, same marker/result
  protocol.
- Hold TERM ignored across the `hermes update` invocation and
  log-and-ignore the single teardown TERM that can still arrive after
  the desktop PID dies (durable SIGNAL breadcrumb for diagnosis).
- Delay start_ui until the desktop PID is gone plus 1s so the shim
  server/window are never born inside the teardown window.
- Run both UI processes in their own sessions; keep SIGTERM/SIGHUP
  ignored in the shim server and stop it with SIGKILL, so a stray TERM
  can no longer leave the progress window on a dead loopback URL while
  the update continues.

Verified on a production git install (macOS arm64, Darwin 27.0,
v0.20.1): six consecutive Desktop-triggered/production-shape updates
completed end-to-end including a full desktop rebuild + codesign; the
shim survived a deliberately injected TERM+HUP mid-update and a full
`hermes desktop --force-build --build-only` running alongside it.

Fixes the macOS reproductions in #66753.

Subject: [PATCH 153/376] fix(deps): exempt no-upload-date and exact-pinned
 packages from exclude-newer bricking
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The relative exclude-newer = "14 days" cutoff bricks installs whenever the
resolver cannot see (or accept) a package's upload date:

- defusedxml / python-olm / unpaddedbase64 (#80387, #79434): ancient frozen
  releases (2021-2023) whose upload dates are often absent from mirror
  indexes and stale uv HTTP caches. uv then filters them entirely
  ("there are no versions of defusedxml"), breaking [youtube]/[wecom]/
  [matrix] resolution and daily `uv sync --locked` runs.

- setuptools / pillow / mcp (#78227, #75992, #76020): exact-pinned deps.
  When the pinned version's upload date is invisible, the resolver filters
  the ONLY acceptable candidate — setuptools==83.0.0 in
  [build-system].requires meant the project could not even be built from a
  git checkout on released v0.20.0. Exempting an exact pin costs nothing:
  the version cannot float without a reviewed pin bump.

Changes:
- pyproject.toml: add all six to the existing exclude-newer-package
  whitelist, with rationale comments per class.
- uv.lock: regenerated; diff is the whitelist metadata only (verified
  zero version drift, still 249 packages).
- tests/test_packaging_metadata.py: new standing guard
  test_build_system_requires_exempt_from_exclude_newer — every
  [build-system].requires package must be whitelisted while a relative
  exclude-newer cutoff is configured. Verified both directions (fails
  when setuptools is removed from the whitelist).
- scripts/install.sh: fix the stale tier-name comparison ("all (with
  RL/matrix extras)" vs actual "all") that mislabeled every successful
  Tier-1 install as a fallback-tier install (#79434 bonus finding).

Verification: uv lock --check green on uv 0.11.19 and 0.12.5;
uv sync --extra all --locked green; uv pip install -e '.[all]' resolves;
whitelist mechanism A/B-proven on a minimal project (unsatisfiable ->
resolves; build-requires variant: uv build fails -> succeeds).

Subject: [PATCH 154/376] fix(gateway): never persist a hygiene compression
 that grows the transcript

Session hygiene could persist a compressed transcript LARGER than the
original (observed: 427K -> 598K), when the generated summary was bigger
than the middle it replaced. Compare like-for-like (both rough estimates)
before persisting a rotated transcript; on growth, keep the original
unchanged so a failed compression is a strict no-op, never a net increase.

in-place compaction commits inside compress_context() via
archive_and_compact — before the gateway can inspect the result. Add the
anti-growth check at the commit site so both paths are covered: a
compression whose rough output exceeds its input is a strict no-op
(original transcript kept durable, session identity untouched).

Covers the observed failure where session hygiene persisted 426 -> 426
messages and ~379K -> ~688K tokens.

Subject: [PATCH 157/376] refactor: bind gateway anti-growth guard to locals,
 trim overlong comment

Simplify-code pass: gateway/run.py called estimate_messages_tokens_rough
6x on the same data in the anti-growth guard (condition + warning f-string).
Bind to _hyg_in_toks/_hyg_out_toks locals like the conversation_compression.py
guard already does. Also trim the comment from 10 lines to 4 (keep the WHY,
drop the WHAT) and remove an extra blank line before TestCompactedTurnsStaySearchable.

Subject: [PATCH 158/376] fix(agent): reword SKILLS_GUIDANCE trigger and stop
 mislabelling its 400 as billing
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

On an Anthropic subscription OAuth credential, every request failed with
HTTP 400 "You're out of extra usage. Add more at claude.ai/settings/usage".
That is not a billing condition: Anthropic's server-side content filter rejects
the first sentence of Hermes' own built-in SKILLS_GUIDANCE prompt, and the
rejection is surfaced with a billing-shaped message. Because the message points
at the usage settings page, it reliably sends people to buy quota they do not
need — the reporter lost three debugging sessions to it.

Bisected against the live API with the real 71,721-char assembled prompt: the
first SKILLS_GUIDANCE sentence alone reproduces the 400 and removing it alone
clears it. Size was ruled out (20 KB of unrelated filler returns 200) and so was
the system[0] identity gate (that returns 429, a different failure).

Three changes, all serving the same outcome — a subscription user can no longer
be misdirected by this 400:

- agent/prompt_builder.py: reword the triggering sentence to the phrasing the
  reporter verified returns 200. Meaning, the skill_manage reference, and the
  ## Skill Safety Rule block are all preserved. The reword is empirically
  validated rather than understood, so a comment records the bisect and warns
  that any rewrite must be re-verified against an OAuth token, not an API key.

- agent/conversation_loop.py: the Anthropic branch of the billing guidance no
  longer asserts exhaustion as fact. It hedges the opening line, names the
  content-filter alternative, and gives the operator a way to tell the two apart
  (if the usage page still shows quota, suspect a content rejection). It also
  points at `hermes auth reset anthropic`, because the credential exhaustion
  latch replays the stored error for ~60 min without issuing a request — which
  makes a real fix look like it did not work.

- hermes_cli/auth.py: document that CLAUDE_CODE_OAUTH_TOKEN is an OAuth token,
  not an API key, despite auth_type="api_key". It stays in api_key_env_vars
  because that tuple doubles as the credential-discovery list; removing it would
  stop Hermes finding a `claude setup-token` credential at all.

Docs updated to match the reworded prompt.

Fixes #82154

Subject: [PATCH 159/376] fix(agent): carry the ambiguity of Anthropic's 'out
 of extra usage' 400 through classification, cooldown, and terminal surfaces

Review follow-up (egilewski): the previous commit only hedged the guidance
text; the exact Anthropic 400 was still classified, persisted, and surfaced
as confirmed billing exhaustion. Carry the ambiguity all the way through:

- agent/error_classifier.py: 'out of extra usage' matches on the 400 and
  status-less paths now attach error_context {billing_unverified,
  possible_content_filter}. Reason stays FailoverReason.billing (rotation +
  fallback remain the right recovery either way); ClassifiedError grows a
  billing_unverified property.

- agent/credential_pool.py: new FAILURE_REASON_BILLING_UNVERIFIED. An
  unverified billing exhaustion gets the short transient cooldown instead of
  the one-hour bench, regardless of pool size: a content-filter rejection
  leaves the credential healthy and fails identically on every key, and the
  hour-long sole-credential latch is what replayed the stored error and made
  real fixes look ineffective. A true 402 keeps the full bench. The marker
  persists with the entry so a restart cannot upgrade it back to a bench.

- agent/agent_runtime_helpers.py + run_agent.py: recover_with_credential_pool
  threads billing_unverified and hands the pool 'billing_unverified' as the
  persisted failure_reason.

- agent/conversation_loop.py: the fallback-switch status, max-retries status,
  terminal label, and both structured terminal results hedge when the verdict
  is unverified. New _billing_terminal_label + _billing_failure_result build
  the returned terminal response in one place; the result dict now carries
  billing_unverified and the billing_block gains 'unverified': true. The
  confirmed-billing path (a real 402 or an API-key credit depletion) keeps
  the original assertive wording, so the caveat no longer dilutes it.

Regression tests: classifier marking (400 + status-less + unambiguous-body
negative), pool cooldown TTLs + persistence round-trip, pool failure_reason
plumbing, and the returned terminal response for both unverified and
confirmed verdicts.

Note: tests/agent/test_credential_pool_routing.py::TestFailureAttribution::
test_unmatched_key_does_not_retry_only_pool_entry fails identically on
current main without this change (pre-existing, unrelated).

Subject: [PATCH 163/376] fix(cron): fall back on transient DNS during provider
 resolve
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Agent crons resolve OAuth credentials before the agent loop. A short
macOS/WARP DNS blip raised httpx.ConnectError ([Errno 8] nodename nor
servname provided) from xai-oauth token refresh, and the scheduler only
walked fallback_providers on AuthError — so Daily Focus Kickoff died
even when XAI_API_KEY / Anthropic were healthy.

Treat ConnectError/DNS OSError (and cause-chain equivalents) like
AuthError when selecting the fallback chain. Keep provider+model atomic.
Regression test covers the ConnectError path.

Subject: [PATCH 164/376] fix(cron): make transient-DNS classification
 platform-safe

The errno literal set {8, 7, 11, 51, 60, 61, 65} mixed macOS getaddrinfo
constants with errno values: on Linux socket.EAI_NONAME is -2 and
EAI_AGAIN is -3, so genuine DNS failures were missed while unrelated
OSErrors carrying errno 8/11 (ENOEXEC/EAGAIN semantics differ) could be
misclassified as transient. Classify socket.gaierror against the EAI_*
constants and plain OSError against named errno constants instead.

Addresses the platform-portability review on #83977.

+Cron also bounds post-run session and agent-resource cleanup. This happens after the LLM turn returns, so it is separate from the inactivity timeout. The default is 10 seconds per cleanup operation. If a storage or client finalizer stops returning, the scheduler logs an error, releases the job's in-flight guard, and allows later runs to dispatch instead of skipping that job forever.

Subject: [PATCH 166/376] test(cron): adapt guard-leak regression to
 owner-fenced dispatch on main

The salvaged regression from #86582 predates the claim_job_for_fire
owner-fencing that landed with #70638; mock the claim and heartbeat so
the healthy job actually runs through the fenced flow.

Subject: [PATCH 170/376] fix(session-search): narrow lineage escape to
 reset/compression; trust SQL child classifier
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Follow-up on the salvaged #85764 commits, addressing review findings:

- _session_left_live_context now allowlists end_reason == 'compression'
  or a fresh reset (_FRESH_RESET_END_REASONS) instead of accepting any
  non-None end_reason. The wide predicate let 'branched' parents — whose
  transcript /branch verbatim-copies into the child — surface as
  same-lineage recall hits, returning content already in the caller's
  live context (verified empirically vs main).
- _FRESH_RESET_END_REASONS is now derived from the canonical
  hermes_state_common._RESET_END_REASONS (plus CLI 'new_session') instead
  of a third hand-maintained copy, per that tuple's anti-drift comment.
  Import verified cycle-free.
- Browse drops the Python re-check of parent_session_id rows:
  list_sessions_rich (include_children=False) already applies the
  canonical _LISTABLE_CHILD_SQL classifier, and the Python re-check
  re-hid legacy pre-marker reset children the SQL same-key heuristic
  deliberately admits. _has_reset_from_marker (now orphaned) removed.
- Tests: branched-parent exclusion regression guard (mutation-checked:
  fails on the overbroad predicate) + legacy pre-marker reset child
  browse guard. 48/48 pass.

   success path but not in a finally block, so exceptions between
   SessionDB() and db.close() leak the connection.

2. hermes_cli/sessions_cmd.py: sessions repair — SessionDB() created
   inline with no .close() at all, leaking the FD on every call.

Additionally, add a __del__ safety net to SessionDB itself so that
instances orphaned by callers who forget .close() are cleaned up when
garbage collected, rather than pinning FDs alive until process exit
via the atexit hook.

Fixes #83226

Subject: [PATCH 172/376] fix: __del__ delegates to close() for full cleanup

The original __del__ only closed _conn (the writer connection),
skipping the read-only connection pool, token writer thread, and
atexit unregister. Delegates to self.close() instead so all
cleanup paths run. Uses __dict__.get('_conn') guard to stay
safe on partially-constructed instances and during interpreter
shutdown.

Subject: [PATCH 173/376] fix(plugins): register deferred platform client tools
 at discovery (#78050)

Rebased onto current main. `hermes_cli/plugins.py` grew 103KB -> 265KB
across 49 commits since the original branch point, and the attribution
mechanism this change hooks into was replaced along the way: the
`_tools_before` / `_plugin_tool_names` snapshot diff is now a
registration ledger sliced from `registration_start`, and `_plugin_id`
is `plugin_key`.

Re-anchored accordingly:

- Discovery-time pre-registration, module reuse, and the `provides_tools`
  opt-in are unchanged.
- Attribution credits `_predeclared_tools` ahead of the ledger slice,
  since those tools registered before `registration_start` and the slice
  cannot see them.
- A failed materialization no longer carries attribution across. The
  failure path now sweeps the whole ownership ledger for the plugin key,
  not just the `registration_start:` slice, so the pre-registered tools
  are disposed along with the adapter. Attribution and the registry now
  agree at zero instead of reporting tools the process is not serving.

tests/hermes_cli/test_deferred_platform_client_tools.py 13/13.
test_plugins.py, test_plugins_cmd_list.py, test_plugin_cli_registration.py

+
+        A platform plugin can ship two independent things: an inbound adapter
+        (heavy — it imports the platform SDK) and outbound client tools the
+        agent calls like any other tool. Deferring the plugin defers both, so
+        in a CLI/TUI process the client tools never register at all:
+        ``resolve_toolset()`` returns ``[]``, the toolset is missing from the
+        ``hermes tools`` checklist, and even an explicit ``platform_toolsets``
+        entry is dropped because the key is unknown. The same tools work in
+        gateway/web processes only because those materialize every platform at
+        startup (issue #78050).
+
+        Client tools that live in a dedicated ``tools`` submodule can be
+        registered at discovery time instead: importing ``<plugin>/tools.py``
+        does not import the adapter, so the SDK stays unloaded and startup
+        stays cheap. A plugin taking this path must therefore keep its package
+        ``__init__`` import-light and pull the adapter in from inside
+        ``register()`` (as ``plugins/platforms/a2a`` does).
+
+        Opting in is explicit: the manifest must declare ``provides_tools``
+        (the field the plugin list and web server already read to name a
+        plugin's tools, per #78538). Keying off the mere presence of a
+        ``tools.py`` would opt a plugin in by accident — a platform is free to
+        put internal helpers there — and would leave the contract invisible to
+        anyone reading the manifest. ``tools.py`` remains where the code is

Subject: [PATCH 174/376] fix(toolsets): admit explicitly-configured plugin
 toolset keys in _get_platform_tools (#81163)

Layer 2 of the #81163 / #78050 fix: _get_platform_tools computed
plugin_ts_keys = _get_plugin_toolset_keys() but only used
CONFIGURABLE_TOOLSETS in the explicit-config filter, so a user-listed
plugin key like `a2a` in `platform_toolsets.cli: [hermes-cli, a2a]` was
silently dropped. The filter now unions configurable and plugin toolset
keys when evaluating has_explicit_config and when admitting per-key
entries.

Cherry-picked from PR #81190 (Layer 2 hunks only; Layer 1 is covered by
the provides_tools mechanism from PR #78842).

Subject: [PATCH 177/376] fix(gateway): registered_names() honors profile scope
 like is_registered()

The salvaged registered_names() from PR #71582 predates the scoped
platform registry: it read only the process-global _entries/_deferred
maps, but plugin platforms register their deferred loaders under a
profile scope. Result: `hermes tools enable a2a --platform a2a` still
rejected the platform. Union the current-scope maps with the global
ones, mirroring is_registered()'s semantics, under the registry lock.

Subject: [PATCH 178/376] fix(gateway): connect messaging platforms in parallel
 at startup (#83791)

GatewayRunner.start() previously awaited each platform's connect() (with its
own timeout) in a serial for-loop. A single slow/failing platform (e.g.
Telegram behind a dead proxy) delayed every later platform's connect by a full
timeout window, cascading one platform's failure onto WeChat/QQ/etc.

Now the slow connect() calls run concurrently via asyncio.gather while the
serial pre-filter (checks, adapter creation, handler wiring) and the
single-threaded result aggregation (shared-state mutation, error handling)
are unchanged. A failing platform no longer blocks the others.

Adds regression tests proving connect() calls overlap and that one failing
platform leaves the others connected.

Subject: [PATCH 179/376] fix(test): genuinely verify parallel startup connects
 (#83791)

The previous concurrency assertion (slow_start < fast_end) was true under
BOTH the serial and parallel implementations, so it proved nothing -- it
even passed against the old serial code on main. The only assertion that
distinguishes the two is that the fast platform finishes before the slow
one (fast_end before slow_end), which is only possible when the connects
overlap.

Switch the test to record connect start/end events in arrival order
(clock-resolution independent) and assert fast_end precedes slow_end. This
also fixes the Windows failure @zuowen7 reported: time.monotonic() has only
~15 ms resolution there, so two parallel connects could land on the same
tick and defeat any wall-clock comparison -- event ordering cannot.

Verified the new test fails against origin/main (serial) and passes against
this branch (parallel).

 Telegram behind a dead proxy) therefore delayed every later platform's
 connect by a full timeout window, cascading one platform's failure onto

+
+Why event-order, not wall-clock timings
+---------------------------------------
+An earlier version of this test recorded ``time.monotonic()`` around each
+connect() and asserted ``slow_start < fast_end``. That assertion is true in
+BOTH the serial and the parallel world, so it proved nothing:
+
+  serial:   slow_start=0, slow_end=0.300, fast_start=0.300, fast_end=0.300
+            -> 0 < 0.300  (passes, but it's serial!)
+  parallel: slow_start=0, fast_start=0,    fast_end=0.001, slow_end=0.300
+            -> 0 < 0.001  (passes)
+
+The only assertion that distinguishes them is ``fast_end`` occurring *before*
+``slow_end`` (true only when the two connects overlap). We record the
+connect start/end events in arrival order, which is fully independent of clock
+resolution -- ``time.monotonic()`` has only ~15 ms resolution on Windows
+(GetTickCount64), so parallel connects can land on the same tick and defeat any
+wall-clock comparison. Event ordering cannot be defeated by a coarse clock.

Subject: [PATCH 180/376] fix(gateway): cap Telegram cold-start connect so
 startup reaches running fast (#85993)

The initial (pre-running) connect awaited during gateway startup now uses
a capped 45s budget for Telegram instead of the full 180s (#67498) budget.
On timeout the platform is queued for the reconnect watcher, which retries
with the full budget and is_reconnect=True (preserving the offline update
queue, #46621). Combined with the parallel startup connects, an unreachable
Telegram no longer holds the whole gateway out of the running state.

 A second, separate guard refuses to touch the venv while any process is running from its Python interpreter (the Desktop app's backend, a gateway, a Python REPL). Those processes keep native extension files (`.pyd`) locked, and a dependency sync that dies partway on an access-denied error strands the install between versions. This guard is **not** bypassed by `--force`; if you're certain the detected holders are false positives, use the explicit `hermes update --force-venv`.
 
+#### Windows venv recreation is transactional
+
+When the Windows installer must recreate an existing `venv`, it first moves the old directory to a unique `venv.stale.*` name, then creates and verifies the replacement. The old tree is deleted only after `venv\Scripts\python.exe` exists in the new tree.
+
+If the move cannot be completed, the installer stops and leaves the live `venv` untouched. If `uv` fails or reports success without creating the interpreter, any partial replacement is moved to `venv.failed.*` and the previous venv is restored. This keeps the health and blocker checks usable after a failed install.
+
+A `venv.stale.*` or `venv.failed.*` directory can remain when another process still owns a file handle. Close Hermes Desktop, gateways, and Python processes using the install, then retry the install/update; parked directories are cleaned up best-effort after a successful recreation.
+
 Expected output looks like:

 rename-aside fails

When Rename-Item on the live venv is denied, do not fall back to an
in-place Remove-Item that can gut site-packages and leave no rollback.
Also mark venv-blocker probe failures with probe_failed so they cannot
be read as a clear scan (#83149).

Subject: [PATCH 190/376] fix(installer): hold the venv rollback source through
 dependency validation (#83149)

Review finding on PR #83194 (egilewski): Install-Venv committed the venv
transaction as soon as the replacement had a working interpreter, deleting
the parked previous venv. Install-Dependencies is a separate later stage
(a separate process under the stage-per-process bootstrap) and every
dependency tier or the baseline-import gate can still fail after that
point - a failed update could still leave Hermes and the blocker probe
unusable with no rollback source.

Now:
- Install-Venv records the parked backup in venv.pending-backup instead
  of deleting it, and excludes it from the venv.stale.* sweep.
- Install-Dependencies wraps the dependency tiers + baseline-import gate
  in the transaction: Restore-VenvBackup on failure (parks the failed
  replacement as venv.failed.*, renames the previous venv back), and
  Complete-VenvTransaction only after the imports prove the replacement
  usable.
- Source-contract regression tests for the boundary
  (tests/test_install_ps1_venv_transaction_boundary.py).

+"""Transaction-boundary regression for Windows venv recreation (#83149).
+
+Review finding on PR #83194 (egilewski): the rollback source (the parked
+previous venv) was deleted as soon as ``Install-Venv`` saw a working
+interpreter in the replacement — but ``Install-Dependencies`` is a separate,
+later stage (a separate *process* under the stage-per-process bootstrap) and
+every dependency tier or the baseline-import gate can still fail after that
+point. Deleting the backup early re-creates exactly the availability failure
+the transactional recreate exists to prevent.
+
+The contract locked here:
+
+* ``Install-Venv`` records the parked backup in ``venv.pending-backup``
+  instead of deleting it, and its stale-tree sweep excludes that backup.
+* ``Install-Dependencies`` restores the previous venv on failure
+  (``Restore-VenvBackup``) and commits the cleanup only after the
+  baseline-import gate passes (``Complete-VenvTransaction``).
+
+The script only runs on Windows, so Linux CI locks the contract at the
+source level, same approach as tests/test_install_ps1_venv_recreate_safety.py.

+When the Windows installer must recreate an existing `venv`, it first moves the old directory to a unique `venv.stale.*` name, then creates and verifies the replacement. The old tree is deleted only after the dependency install completes and the baseline imports pass in the new tree — until then it is the rollback source (recorded in `venv.pending-backup`).
 
 If the move cannot be completed, the installer stops and leaves the live `venv` untouched. If `uv` fails or reports success without creating the interpreter, any partial replacement is moved to `venv.failed.*` and the previous venv is restored. This keeps the health and blocker checks usable after a failed install.

Subject: [PATCH 191/376] fix: coerce dict-valued model/default config back to
 string across resolution paths

A dict-valued model.default (e.g. {provider:..., model:...}) in config.yaml
was leaking into agent.model and crashing the agent at init:

  AttributeError: 'dict' object has no attribute 'lower'
    agent/agent_runtime_helpers.py: anthropic_prompt_cache_policy

This manifested on the Telegram gateway as an infinite reset loop: every
turn built an agent with model=dict, crashed during init, the gateway
treated the failed turn as a session needing reset, and /reset rebuilt the
agent and crashed again.

Coerce dict -> string at every model-resolution entry point so the value
is normalized once and never reaches a .lower() call as a dict:
- agent/agent_runtime_helpers.py: anthropic_prompt_cache_policy (the crash site)
- agent/agent_init.py: configured default model resolution
- cli.py: CLI config model + _normalize_model_for_provider
- hermes_cli/main.py: _has_any_provider_configured
- hermes_cli/oneshot.py: _run_agent model resolution
- hermes_cli/runtime_provider.py: _get_model_config default handling
- model_tools.py: _resolve_active_context_length

Subject: [PATCH 192/376] fix: keep nested model.default provider paired
 through HermesCLI

The prior dict coercion converted a dict-valued model.default to a plain
model string but dropped the nested provider. On the interactive CLI path
requested_provider then fell back to the outer merged model.provider
(typically "auto", authoritative at runtime resolution), so the model
could be routed through the wrong active provider.

Canonicalize both halves at the shared boundary: _split_model_config_default
flattens a dict-valued default into (model, provider) and HermesCLI.__init__
feeds the nested provider into the requested_provider chain (still below an
explicit --provider argument). new_session reuses the same helper.

Adds regression coverage asserting the nested provider stays paired with the
model, that flat string defaults keep the outer provider behavior, and that
an explicit provider argument still wins.

Subject: [PATCH 193/376] fix: flatten dict-valued model.default at config load
 boundary
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Extends the fix to the config-load chokepoint so every reader sees plain
strings, not just the interactive CLI paths. _normalize_root_model_keys
now flattens a dict-valued model.default/model.model into a string default
plus the nested provider (promoted to model.provider when no explicit
outer provider or "auto" is set), covering the residual readers the
review flagged: doctor, status/dump, fallback picker, prompt-size, and
the context-switch guard — all of which called .strip()/flowed the raw
value and would crash or misroute on a nested dict.

Adds _normalize_root_model_keys regression coverage for the flatten
(precedence, auto-override, explicit-provider-win, alias shape, flat
strings untouched).

Subject: [PATCH 194/376] fix: normalize managed config overlay before merge in
 load_config

The shared load-boundary flatten added for dict-valued model.default only
ran on the user/default merge; _load_config_impl then deep-merged the raw
managed overlay without normalizing, so a managed model.default:
{provider, model} still reached status/fallback/runtime readers as a dict.

Normalize the managed overlay (same _normalize_root_model_keys pass, plus
the bare model-string -> model.default promotion used by
managed_scope.apply_managed_overlay) before expanding and merging, so
every overlay is canonical before load_config returns.

Adds load_config() regressions for a nested managed default and a bare
managed model string.

Subject: [PATCH 196/376] refactor: centralize dict-valued model.default
 coercion via shared helper
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Promote _split_model_config_default to hermes_cli/config.py as the single
shared helper for flattening dict-valued model.default/model.model config.
All 8 defense-in-depth sites now route through it instead of inlining
their own isinstance checks with inconsistent key orders.

Changes:
- Add split_model_config_default() to hermes_cli/config.py (public)
- cli.py: _split_model_config_default delegates to shared helper
- Fix key extraction order: agent_runtime_helpers.py was reversed
  (default->model); now consistent (model->default) across all sites
- Remove provider-as-model-name fallback from main.py, oneshot.py,
  model_tools.py, cli.py — provider is a routing key, not a model ID
- Add 'name' to _normalize_root_model_keys flattening loop and
  _has_nested_default detection to cover the deprecated model.name alias

Tests: 118 passed + 1 skipped (cli_init, managed_scope, config).
E2E: 31/31 passed (config chokepoint, managed scope, crash site,
negative cases, edge cases).

Subject: [PATCH 197/376] fix(desktop): confirm detached updater spawn before
 quitting for hand-off (#66753)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The update hand-off spawned the detached updater, called unref(), and
quit unconditionally after the 2.5s dwell. Node reports exec failures
(ENOENT/EACCES) asynchronously via the child 'error' event, and a
short-lived updater can die inside that window — in both cases the app
vanished with no updater, no relaunch, and no evidence (the reported
macOS incident, and the posix.sh early-death reports on the same
thread).

Add observeUpdaterHandoff(): watch the just-spawned child for 'error'
and early 'exit' during the existing dwell (no added latency — the
dwell doubles as the settle window). Clean exit 0 inside the window
stays a success (the Windows `cmd start` wrapper exits immediately by
design); a spawn error, non-zero exit, or signal death is a failed
hand-off. On failure:

- applyUpdates (Windows hand-off): don't quit — restart the backend and
  surface a structured error to the UI.
- applyUpdatesPosixHandoff (mac/linux): don't quit — surface the error.
- handOffWindowsBootstrapRecovery: return false so the caller falls
  through to its next recovery path instead of quitting into nothing.

The pre-written update marker names the dead child pid, so
readLiveUpdateMarker self-heals it; no marker cleanup needed. Children
without an event interface settle ok after the window, keeping the
observation a best-effort hardening rather than a new way to wedge an
update.

Covered by 7 new unit tests (spawn-error, non-zero exit, signal death,
clean exit 0 wrapper, survival, double-settle, event-less child).

Closes #66753

Subject: [PATCH 198/376] fix(update): gate 'Code updated!' on HEAD actually
 moving (#79678)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A detached/pinned checkout can report 'N new commit(s)' against origin,
run the ff-only merge successfully, and still sit on the old commit
afterward (the branch-switch step re-detaches to the raw SHA). Before
this guard 'hermes update' printed '✓ Code updated!' and reinstalled
deps + rebuilt the desktop app against the stale tree - no error, no
warning, 'hermes doctor' healthy.

Compare pre-pull and post-pull HEAD; if they match, fail loudly with a
reattach hint instead of claiming success.

Subject: [PATCH 199/376] fix(install): surface aborted gateway restart during
 hermes update
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The gateway auto-restart phase in `hermes update` was wrapped in a blanket
`except Exception` that only logged at debug level. When the phase raised
early — e.g. importing `hermes_cli.gateway` from the freshly pulled checkout
inside a process that already loaded pre-update modules — every drain and
restart line vanished from the update output, the update printed
"Update complete!" and exited 0, and the still-running gateway kept serving
pre-update modules against replaced source files. The next Telegram turn died
with `ImportError: cannot import name 'is_trivial_prompt'`.

The handler now probes for surviving gateway processes and, unless it can
positively prove none are running, prints the cause plus a manual recovery
command and marks the fleet restart incomplete — which exits nonzero and
writes the gateway-mode exit-code marker, matching the existing
failed-or-stale-unit path.

Fixes #78574

Subject: [PATCH 200/376] fix(install): fail closed when a stopped gateway
 leaves an empty survivor probe
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Review follow-up (#78574): the aborted-restart handler only flagged the fleet
stale when the post-failure survivor probe was None or non-empty. A positive
empty probe was treated as proof-of-safety — but `[]` is only safe when
nothing was running before the phase. If a gateway was discovered, stopped
(SIGTERM/drain), and its replacement never came back, the probe is empty at
exactly that unsafe moment and the update reported success — the fail-open
contract this fix exists to close.

Snapshot the pre-restart gateway PIDs before any stop/drain and route the
handler decision through a pure _restart_phase_failure_is_incomplete() helper
that fails closed on an empty survivor set whenever a gateway existed
pre-restart (or the pre-state could not be read). Add decision-level regression
tests covering the stopped-without-replacement gap, unknown pre-state, and the
truly-no-gateway positive control.

Subject: [PATCH 201/376] fix(update): verify Windows gateway cold-start
 survives before reporting success
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

_cold_start_windows_gateway_after_update() printed the success line off a
successful Popen return alone, which only proves CreateProcess succeeded,
not that the child survived. On Windows, a job object denying
CREATE_BREAKAWAY_FROM_JOB hard-kills the child during updater teardown
before it logs anything, yet the updater still printed "Starting Windows
gateway after update (PID ...)" — leaving Telegram/Discord/etc. offline
with no indication anything failed (#84185).

Route the success report through gateway_windows._report_gateway_start(),
the same post-spawn liveness poll every other _spawn_detached() caller
already uses, so a dead child is reported as a failure with a
manual-recovery hint instead of a false success.

Subject: [PATCH 202/376] fix(update): detect updater self-lock on Windows +
 repair venvs whose base interpreter is uv-managed
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two gaps left every Windows git-checkout install unable to recover from
the exact failure state #83569 reports:

1. Self-lock detection. _detect_venv_python_processes() always excludes
   the calling process by design — a CLI hermes update IS the venv python.
   An updater that had already imported a native venv extension (the
   canonical one being cryptography.hazmat.bindings._rust, mapped while
   hermes_cli.main resolved external secret sources) passed every
   preflight and then died mid-sync with os error 5 when uv tried to
   rewrite the mapped .pyd, stranding the venv half-updated. A new
   preflight now refuses the sync before touching the checkout, writes
   the update-incomplete marker so the next fresh launch completes the
   install, and exits 2. Verified on a live Windows 11 host: after
   importing hermes_cli.main, tasklist /m _rust.pyd shows the .pyd mapped
   in the caller, and a peer process cannot open it read-write
   (Permission denied) — while a rename succeeds, matching how uv/pip
   actually fail (truncate+write, not rename).

2. Early-recovery install path. _early_recovery._run_repair_install used
   sys.executable -m pip unconditionally. Windows git checkouts install
   on a uv-managed base interpreter (python-build-standalone), whose
   EXTERNALLY-MANAGED marker makes plain pip abort with
   externally-managed-environment — the repair no-oped and the venv
   stayed broken. The repair now detects the PEP 668 marker, prefers
   uv pip install with VIRTUAL_ENV pointed at the project venv, and
   falls back to pip --break-system-packages when no uv binary exists.

Both fixes ship with subprocess/unit regressions (sabotage-verified):
the new tests fail on pre-fix code and pass with it. Complements #77517,
which keeps the updater from importing cryptography in the first place;
this PR is the defence-in-depth when any future path loads it anyway.

Fixes #83569

Subject: [PATCH 203/376] fix(update): complete pending core install before any
 native import (self-lock loop fix)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Reviewer egilewski found the original defer was circular (#83590 comment):
the self-lock preflight wrote .update-incomplete and exited, but the next
launch only ran the full recovery AFTER main.py's third-party imports —
so a healthy venv's probes made the early pass a no-op, main.py imported
cryptography eagerly, the .pyd got mapped again, and the deferred install
re-hit the exact self-lock it was meant to escape.

Close the loop by making the marker guarantee the install runs BEFORE any
native extension can be imported:

- hermes_cli/_install_repair.py (new, stdlib-only): single source of truth
  for the core .[all] reinstall — ensurepip bootstrap, uv-pip/pip
  resolution with VIRTUAL_ENV, Termux env stripping, Windows hermes*.exe
  quarantine, per-extra fallback ladder, and fd1→fd2 routing for acp
  safety.  Deliberately free of managed_uv/hermes_constants imports so it
  stays importable in the corrupted-venv state it exists to repair.
- hermes_cli/_early_recovery.py: recover_if_needed now completes a pending
  .update-incomplete install BEFORE the import probes, on every launch
  that sees the marker (unless argv is update).  Success clears the
  marker; failure bumps an attempts counter inside the marker body and
  keeps it.  A 3-attempt ceiling stops a persistently-failing install
  from reinstall-hammering every launch (hermes acp included) — past the
  ceiling the late post-import recovery takes over with its manual
  recovery instructions.  Single-flight lock shared with the late path.
- hermes_cli/main.py: _recover_core_update_marker_locked delegates the
  install to the shared executor (no duplicated logic); ensure_uv stays
  in the late path so a venv whose uv vanished mid-update still
  bootstraps it.
- tests: 7 new regressions — the reviewer's exact case (marker + healthy
  venv → install runs while sys.modules has no cryptography), failure
  keeps marker + increments attempts, retry ceiling, lazy marker does
  not trigger core install (#58004 invariant), argv-update skip, and
  corrupt/missing marker bodies.  The key test was sabotage-verified:
  removing the pre-import branch makes it fail with zero install calls,
  while a lone-lazy-marker test still passes; restoring the branch makes
  it pass again.

Subject: [PATCH 204/376] test(update): mock gateway discovery now that the
 restart phase is surfaced

The gateway auto-restart phase used to swallow every exception at debug
level, so tests driving cmd_update end-to-end never noticed it touching
real gateway discovery. With #78574 surfacing an aborted restart as a
failed update, an unmocked find_gateway_pids on a box with a live
gateway hits the conftest live-system guard and turns into a spurious
sys.exit(1).

Add an autouse fixture in test_cmd_update.py (discovery returns nothing,
systemd unsupported) and the same seams in test_update_head_moved_gate's
helper so the phase is a clean no-op for tests that do not assert on
gateway restarts.

Subject: [PATCH 207/376] fix(agent): anchor ZAI/Kimi base_url host matching to
 avoid substring false positives

_to_openai_base_url() matched ZAI (open.bigmodel.cn, api.z.ai, bare
"bigmodel") and Kimi (api.kimi.com) via `substring in url`, so any custom
gateway whose base_url happened to contain one of those strings as a path
segment (e.g. a reverse-proxy prefix like /proxy/bigmodel-fallback/) was
silently misrouted to the wrong OpenAI-wire endpoint shape.

This is the same false-positive class 6f33f510e8 just fixed for the
MiniMax branch in the same function by switching to base_url_host_matches()
(hostname-anchored). Apply the same fix to the ZAI and Kimi branches, which
that commit didn't touch. Drops the bare "bigmodel" substring check since
open.bigmodel.cn is the only canonical bigmodel-family host referenced
anywhere else in the codebase (agent/model_metadata.py, hermes_cli/auth.py).

Added regression tests mirroring the MiniMax marker-in-path tests added in
the same commit.

Subject: [PATCH 208/376] fix(routing): use hostname match for azure.com
 endpoint detection (#74312)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replace raw substring checks ("azure.com" in full_url) with the existing
base_url_host_matches() helper at two sites in runtime_provider.py.

The substring approach misclassified URLs whose path (not hostname)
contained "azure.com" — e.g. https://example.invalid/proxy/azure.com/v1 —
causing the wrong credential (Azure key instead of explicit Anthropic token)
to be selected, and potentially leaking a more-privileged Azure key across
a trust boundary.

base_url_host_matches() parses the URL and validates only the hostname
against allowed Azure suffixes with proper boundary rules.

Fixes #74312

Subject: [PATCH 209/376] fix: widen base-URL hostname identity class to
 remaining substring sites

Follow-up to #85737, which migrated five provider-identity sites onto
utils.base_url_host_matches()/base_url_hostname(). This completes the class
sweep (never-patch-predicates: one owner, every site) and folds in the two
open contributor PRs attacking individual sites:

- agent/auxiliary_client.py ZAI/Kimi OpenAI-wire rewrite (PR #85715,
  pierrenode): 'bigmodel'/'api.z.ai'/'api.kimi.com' substring checks
  rewrote proxy paths containing those markers.
- hermes_cli/runtime_provider.py Azure endpoint detection (PR #74721,
  RelaxJonh, issue #74312): 'azure.com' substring picked the Azure key
  for non-Azure hosts whose path contained the text.
- run_agent.py: _is_azure_openai_url, _is_copilot_url, Anthropic
  credential-refresh azure guard, _anthropic_preserve_dots host
  allowlist, OpenRouter/mistral reasoning gates.
- agent/chat_completion_helpers.py: nousresearch / nvidia detection.
- agent/conversation_loop.py: GitHub Models 413 hint.
- agent/usage_pricing.py: localhost billing-route detection.
- hermes_cli/model_switch.py: api.openai.com catalog fallback and
  localhost custom-provider detection.
- cli.py: local-model autodetect and Ollama/LM Studio context-length
  hints (port-anchored instead of '11434' in URL).
- tools/mcp_oauth.py: Figma remote-MCP detection.
- tools/skills_hub.py: raw.githubusercontent.com source-URL check.

Regression tests extend tests/hermes_cli/test_base_url_host_identity.py
(azure/copilot/dotted-model/figma proxy-path + lookalike cases) and
tests/agent/test_minimax_auxiliary_url.py (ZAI/Kimi path false positives).

Closes #74312. Salvages #85715 and #74721 with authorship preserved.

Subject: [PATCH 210/376] docs: document provides_tools client-tool
 registration for platform plugins

Follow-up docs for PR #86660 (#81163/#78050): platform-adapter developer
guide gains a `provides_tools` section (deferred adapters vs eager client
tools, tools.py convention, per-platform enablement incl. plugin platform
names as --platform targets); a2a user guide shows the concrete enable
commands including the inbound-task chaining case.

+#### Outbound client tools: `provides_tools`
+
+`kind: platform` plugins are **deferred**: the adapter module (and its SDK
+imports) only load when a gateway, cron, or `send_message` path first asks the
+platform registry for the platform. If your plugin also ships outbound *client
+tools* the agent should be able to call from any session (the bundled `a2a`
+plugin's `a2a_call` / `a2a_discover` etc.), put them in a dedicated `tools.py`
+with a `register_tools(ctx)` function and declare them in the manifest:
+
+```yaml
+provides_tools:
+  - my_platform_call
+  - my_platform_list
+```
+
+With `provides_tools` declared, Hermes imports only `tools.py` during plugin
+discovery and registers the client tools in every process — CLI and TUI
+included — while the adapter stays deferred. Keep the package `__init__.py`
+import-light and pull the adapter in from inside `register()` so the eager
+import stays cheap. Without the field, nothing changes: the whole plugin stays
+deferred.
+
+Users enable the toolset per platform like any other, e.g.
+`hermes tools enable my_platform --platform cli`, or by listing the toolset
+key under `platform_toolsets` in `config.yaml`. Plugin platform names are
+also valid `--platform` targets, so an inbound session on your platform can
+be granted its own outbound tools.

Subject: [PATCH 211/376] fix(streaming): join stream worker and drain Relay
 scopes on interrupt

Empty-stream stalls that trip interrupt were raising InterruptedError
before the stream worker closed its physical LLM scope, corrupting the
Relay LIFO stack and cascading into a CLI EIO redraw storm (#81521).

Subject: [PATCH 213/376] fix(streaming): widen #81521 interrupt join to
 sibling paths and use version-correct Relay top accessor

Follow-up to HexLab98's salvaged commits:

- Apply the same bounded worker join before raising InterruptedError at
  the two sibling interrupt sites that share the raise-without-join
  shape: the non-streaming API poll loop and the Bedrock streaming poll
  loop. Both workers run Relay-managed physical attempts, so raising
  immediately allowed turn teardown to race a still-open physical scope
  exactly as in the streaming path.

- Address the #81601 review finding (egilewski): the pinned nemo-relay
  binding's get_scope_stack() returns a native ScopeStack object which
  scope.pop rejects with TypeError, so the orphan drain never drained
  under the real binding. current_top() now prefers the version-correct
  scope.get_handle() accessor and falls back to the old list-unwrap for
  fake/legacy shapes. Handle comparisons go through same_handle(),
  comparing by uuid, because native ScopeHandle instances do not
  implement value equality.

- Add a real-binding regression test that reproduces the orphaned-scope
  session close against the pinned native wheel (skips where the native
  binding is unavailable), alongside the existing fake-based coverage.

 timeout
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The salvaged _close_scope_handle replaced direct scope.pop calls that
were bounded by _SCOPE_OP_TIMEOUT with an unbounded run_in_session
callback, regressing the bounded-finalization contract (CI:
tests/agent/test_relay_runtime_bounded_scope_ops.py — end_turn /
close_session / finish_logical_calls hung when the native pop wedged).
Pass timeout=_SCOPE_OP_TIMEOUT so the whole drain+close costs at most
one span and never blocks turn or session completion.

Subject: [PATCH 215/376] fix(streaming): gate the interrupt worker join on
 live Relay managed execution
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The unconditional 2s join before InterruptedError delayed interrupt
detection when Relay managed execution was not active (CI:
tests/run_agent/test_interrupt_propagation.py — detection took 2.34s
against a <1.0s budget, because the mocked worker sleeps 5s and there
is no Relay scope to unwind).

Extract the join into _join_worker_for_relay_teardown(), which no-ops
unless a Relay runtime exists AND managed execution consumers are
registered — the only case where an orphaned physical scope can corrupt
the LIFO stack (#81521). Applied at all three interrupt sites
(streaming, non-streaming, Bedrock streaming). The regression test now

Subject: [PATCH 217/376] fix(kanban): re-create the schema when a cached DB
 path loses it (#83445)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`connect()` caches every path it has initialized in the process-local
`_INITIALIZED_PATHS` set and then skips all first-open work for it —
header validation, integrity probe, `SCHEMA_SQL`, additive migrations.
That cache is keyed on a path, but the schema it stands for lives in a
file, and the two can drift apart: delete or replace `kanban.db` under a
live gateway/dispatcher/dashboard process and the next `connect()` takes
the fast path, lets SQLite create a fresh empty database, and hands back
a connection with no tables in it.

Nothing notices. Every query then fails with `no such table: tasks`,
`plugin_api._conn()` logs its init warning and carries on, and the board
renders empty. Because the cache entry survives, the process re-creates
the same schema-less ~4 KB file on every restart of the desktop app in
front of it — only killing the backing process clears it.

Verify the sentinel table on the fast path and self-heal when it is gone:
drop the stale cache entry and fall through to the existing init path,
which re-runs the probes and the schema script under the cross-process
init lock. The check is one `sqlite_master` lookup on the already-resident
page 1, so the steady-state path stays lock-free (#36644) and does no
schema work.

Subject: [PATCH 219/376] fix(desktop): give chat images native right-click and
 proper save filenames

Three fixes for generated/displayed images in the desktop chat:

- Shell fallback context menu no longer swallows right-clicks on images:
  the guard now yields to Electron's native image menu (Copy Image, Copy
  Image Address, Save Image As...) for img/picture/video/canvas targets,
  matching the existing editable/selection carve-outs.

- Save Image As / download button: generated-image URLs (fal.media etc.)
  end in an extensionless content hash, so saves produced an unopenable
  "All Files" blob. The main-process save dialog and the renderer anchor
  fallback both now append a MIME-derived extension, add image type
  filters, and default to the user's Downloads directory instead of the
  process cwd (win-unpacked on packaged Windows installs).

- New will-download handler routes any Chromium-initiated download
  through the same Downloads-dir + guaranteed-extension policy.

Validation: new unit tests for the filename derivation (6 passing);
npm run check:lint green (tsc x3 + eslint, 0 errors).

Subject: [PATCH 220/376] fix(desktop): suppress skill suggestion pill when the
 session already touched the skill

The composer's "Use skill: X" pill only checked the draft text and the
workspace-name collision - it happily re-offered a skill the session had
already loaded (skill_view), edited (skill_manage), or that the user had
invoked via its /name command. Clicking it would re-inject the full
SKILL.md into a context that already carries it.

The draft provider now scans the session transcript (per-runtime
$sessionStates mirror, $messages for the active session) for
skill_view/skill_manage tool calls naming the skill - exact or qualified
(category/name, plugin:name), from parsed args or hydrated argsText -
and for user turns starting with the skill's slash command, and stands
down on a hit. The scan only runs when the draft actually matched a
skill, so ordinary typing pays nothing.

Subject: [PATCH 225/376] fix(install.ps1): surface uv installer errors and add
 GitHub + existing-uv fallbacks (#69216)

Install-Uv piped the astral installer's entire output to Out-Null, so any
real failure (proxy block, AV quarantine, permissions) surfaced only as the
generic "uv installed but not found" message, and astral.sh was the sole
install source even though corporate proxies commonly block it while the
byte-identical GitHub releases installer downloads fine.

Three-rung ladder, all inside Install-Uv:
1. astral.sh installer with output captured via Tee-Object.
2. GitHub releases installer mirror (same UV_INSTALL_DIR).
3. Salvage an existing uv.exe (Get-Command uv, or the astral default
   %USERPROFILE%\.local\bin\uv.exe) by copying it into $HermesHome\bin so
   the managed-first invariant holds.

On total failure, print the last 15 lines of captured installer output plus
the existing manual-install pointer.

Reported by @BitBernd; proxy diagnosis by @gakugaku; Out-Null suppression
first identified by @webtecnica in #69366.

Closes #69216

+"""Regression: Install-Uv must surface installer errors and have fallbacks.
+
+Issue #69216: Windows installs died with only the generic message
+``uv installed but not found at ...\\bin\\uv.exe``.  Two root causes:
+
+1. ``Install-Uv`` piped the astral installer's entire output straight into
+   ``Out-Null`` (``2>&1 | Out-Null``), so any real failure -- download error,
+   corporate proxy block, AV quarantine, permissions -- was swallowed and
+   the user only ever saw the generic post-condition failure (first
+   identified in #69366).
+2. There was exactly one install source, ``astral.sh``.  Corporate proxies
+   commonly block astral.sh while the byte-identical installer published at
+   GitHub releases downloads fine (diagnosed by @gakugaku on #69216).
+
+The fix installs a three-rung ladder inside ``Install-Uv``:
+
+- Rung 1: astral.sh installer, output captured via ``Tee-Object``.
+- Rung 2: GitHub releases installer mirror, same ``UV_INSTALL_DIR``.
+- Rung 3: salvage an existing ``uv.exe`` (``Get-Command uv`` or
+  ``%USERPROFILE%\\.local\\bin\\uv.exe``) by copying it into
+  ``$HermesHome\\bin\\uv.exe`` so the managed-first invariant holds.
+
+Only after all three rungs fail does it error out -- and then it prints the
+tail of the captured installer output so the real cause reaches the user.
+
+install.ps1 only runs on Windows, so these tests lock the contract at the
+source-text level (same style as test_install_ps1_uv_powershell_host.py).

Subject: [PATCH 226/376] fix(guard): steer live-checkout block message to
 disk-backed scratch clones

The guard's "use a separate worktree or temporary clone" advice sent
agents to /tmp by default. /tmp is RAM-backed tmpfs on most distros, and
parallel salvage clones each running npm ci (~1.6GB per clone) filled a
32GB tmpfs to 97% during a 15-subagent campaign, ENOSPC-ing sibling test
runs. The message now recommends `git clone --shared <root> ~/.hermes/scratch/<task>`
(honoring HERMES_HOME), warns that dependency installs belong on real
disk, and tells the agent to delete the clone once the branch is pushed.

Subject: [PATCH 227/376] fix(managed_uv): fall forward to next Python minor
 when current line has no fixed SQLite build

When every patch on the current minor line (e.g. 3.11) still links a
vulnerable SQLite (e.g. 3.50.4 on Windows), the provisioner now tries
the next supported minor line (3.12, then 3.13) before giving up.

Previously, _install_safe_python_generation only tried patches within
the same minor line. On Windows, where python-build-standalone may not
publish a fixed build for the installed patch, users were stuck with a
repeated warning on every `hermes update` with no path forward.

The requires-python constraint (>=3.11,<3.14) and the downstream
import smoke test already gate compatibility, so the minor-line
upgrade is safe.

Adds allow_minor_upgrade parameter to _attempt_install_generation to
relax the same-minor-line version guard when called from the fallback
path.

Fixes #76106

Subject: [PATCH 228/376] test(managed_uv): cover explicit-patch fallback on
 the next minor line; dedupe retried versions

Follow-up to the salvaged #76252 addressing both review gaps:

- New TestMinorLineFallForward class with a direct test of the
  explicit-patch fallback branch: bare '3.12' resolves to a VULNERABLE
  build while an explicit 3.12.x patch is fixed, so recovery must go
  through _list_available_patches on the next minor line. Asserts the
  exact `uv python install` request sequence.
- New all-minors-exhausted test: everything vulnerable on 3.11-3.13
  returns None with per-line attempts bounded by _MAX_PATCH_RETRIES and
  no requests beyond 3.13 (requires-python is <3.14).
- test_retry_is_bounded_by_max_retries_constant now actually uses its
  counting wrapper and asserts the collected install calls (the
  previous version collected them into a dead variable).

Also dedupes the fallback loop the same way the same-minor loop does:
_attempt_install_generation can now record the probed candidate version
into a caller-supplied tried_versions set, so the explicit-patch pass
skips the version the bare-minor request already resolved to and
rejected -- previously that wasted a full download+install+probe+delete
cycle per minor line re-trying a known-vulnerable build.

Subject: [PATCH 229/376] fix(cache): keep prompt_cache_key warm across
 compression session rotation

Legacy compaction mode (compression.in_place: false) rotates the physical
session_id mid-conversation. The prompt-cache scope introduced in #79161 was
derived from that physical id, so every rotation moved the same conversation
into a fresh cache bucket - the prompt cache went cold at every rotation
boundary (#79017).

Fix: resolve a rotation-stable logical scope - the compression-lineage ROOT
of the current session (SessionDB.get_compression_lineage, fork-aware
post-#79193) - once per turn, memoized per transcript segment, and prefer it
over the physical session_id at every prompt_cache_key derivation site:

- agent/prompt_cache_scope.py (new): resolve_prompt_cache_scope(agent) -
  lineage-root walk with per-segment memo; falls back to the physical id
  when no DB is attached or the walk fails, degrading to pre-fix behavior.
- transports/codex.py: build_kwargs accepts cache_scope_id and prefers it
  for the body prompt_cache_key, the xAI x-grok-conv-id header, and the
  Codex x-client-request-id routing header. The Codex session_id header
  keeps the raw physical id (transcript identity, #57012 contract).
- transports/chat_completions.py: _add_prompt_cache_key accepts
  cache_scope_id with the same precedence.
- chat_completion_helpers.py: build_api_kwargs threads the resolved scope
  into all three build_kwargs call sites (codex, profile, legacy).
- auxiliary_client.py: set_runtime_main carries cache_scope; the aux
  Responses cache-key site prefers it over the physical session_id.
- turn_context.py: resolves the scope once per turn and threads it through
  set_runtime_main (no DB walk on the per-API-call hot path).

Scope semantics preserved from #79161: /new starts a fresh scope (new
lineage), /branch children, delegate subagents, and tool children stay
isolated (explicit-fork exclusion in get_compression_lineage), unrelated
sessions keep distinct buckets, and cron per-fire timestamps still
normalize via _cache_scope_from_session_id.

Default installs compact in place (session_id never rotates), so they hit
the memo and produce byte-identical keys to before.

Fixes #79017

+"""Rotation-stable logical cache scope for prompt_cache_key derivation.
+
+Context-compression rotation (legacy ``compression.in_place: false`` mode)
+mints a new physical ``session_id`` mid-conversation to segment the
+transcript. The prompt-cache scope introduced by #79161 was derived from that
+physical id, so every rotation moved the conversation into a fresh cache
+bucket even though it is logically the same conversation continuing
+(issue #79017).
+
+``resolve_prompt_cache_scope()`` maps the physical session id to the ROOT of
+its *compression lineage* — the pre-rotation session id — using
+``SessionDB.get_compression_lineage()``, whose fork-aware semantics
+(hardened in #79193) give exactly the scope boundaries the cache key needs:
+
+- compression-rotation children walk back to the original segment
+  (rotation-stable scope — the fix);
+- ``/new`` starts a lineage-less session (fresh scope);
+- ``/branch`` children (``_branched_from``), delegate subagents
+  (``_delegate_from``), and tool-tagged children (``source="tool"``) are
+  explicit fork children and keep their own isolated scope, preserving the
+  sibling/subagent isolation #79161 established;
+- cron fires keep their physical ``cron_<job>_<ts>`` id here — the per-fire
+  timestamp is stripped later by ``_cache_scope_from_session_id`` exactly as
+  before.
+
+The resolution is memoized per (agent, session_id): the lineage walk runs
+once per transcript segment — NOT per API call — and re-runs only when
+rotation actually changes ``agent.session_id`` (per the no-DB-on-the-hot-path
+constraint recorded on #79017). Default installs compact in place and never
+rotate, so they hit the memo forever and behave byte-identically to before.

Subject: [PATCH 230/376] refactor(cache): fold self-review findings on the
 rotation-scope fix

- prompt_cache_scope: memo key now includes DB presence (a lazily attached
  _session_db re-resolves instead of staying pinned to the physical id);
  _persist_disabled agents (background-review forks that never get a DB row)
  memoize the fallback instead of re-querying the lineage per API call;
  module docstring cross-references get_conversation_root and why the two
  lineage resolvers must not be deduplicated.
- chat_completion_helpers: hoist the triplicated
  _prompt_cache_scope_for_agent(agent) call to a single local above the
  OpenAI-wire dispatch (after the anthropic/bedrock early returns, which
  don't use prompt_cache_key).
- codex transport docstring: x-client-request-id mirrors the derived body
  key, not the raw scope id.
- turn_context comment: acknowledge the first-turn pre-persist fallback.
- tests: +2 (persist-disabled memoization; lazy DB attach re-resolution).

Subject: [PATCH 231/376] refactor(cache): never-raising scope resolver shared
 by both call sites
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

/simplify-code finding: turn_context evaluated resolve_prompt_cache_scope()
inside set_runtime_main's argument list under the umbrella try/except — a
resolution failure would silently skip the ENTIRE runtime binding
(provider/model/base_url/api_key/session_id for all aux calls that turn),
not just the cache scope.

- prompt_cache_scope: add resolve_prompt_cache_scope_safe() (never raises,
  returns None on failure/empty).
- turn_context: resolve the scope into a local via the safe variant BEFORE
  the set_runtime_main call, so a failure can only lose the scope.
- chat_completion_helpers: _prompt_cache_scope_for_agent delegates to the
  shared safe variant (guarded import retained).
- tests: +1 (hostile-property agent -> None; normal/empty passthrough).

Subject: [PATCH 232/376] =?UTF-8?q?feat(desktop):=20multi-connection=20reg?=
 =?UTF-8?q?istry=20=E2=80=94=20named=20agent=20sources=20(schema=20v2=20+?=
 =?UTF-8?q?=20IPC=20+=20Settings=20UI)?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

First slice of multi-source agent support: the desktop can now persist ANY
number of named backends (local runtime, remote gateways, Hermes Cloud
instances, SSH hosts) side by side instead of one global connection plus
per-profile overrides.

- electron/connection-registry.ts: pure v2 registry module — required
  case-insensitively-unique labels (device names), @name-device handle rule
  for duplicate profile names across sources (agentHandle), defensive
  normalizeRegistry for corrupt files, one-time v1→v2 migration that imports
  the global block + per-profile overrides (deduped by URL/host) and leaves
  connection.json untouched for older builds.
- main.ts: connections.json storage beside connection.json (same secret
  posture: safeStorage-encrypted tokens, 0600, tighten-before-parse, mtime
  cache) + hermes:connections:* IPC (list/save/remove/set-primary/test).
  Test maps registry entries onto the existing testDesktopConnectionConfig
  probe stack — no new probe code.
- Settings → Connections: manage the registry (add/edit/remove/test/make
  primary) with forced naming; local entry is non-removable; removing the
  primary retargets to local. en + zh locales.

Storage-level only by design: routing/pool generalization to composite
(connection, profile) keys, the multi-source roster, plugin SDK surface, and
fan-out updates land as follow-up PRs.

+/**
+ * connection-registry.ts
+ *
+ * Pure, electron-free helpers for the desktop's multi-connection registry —
+ * the v2 successor to the single global `mode` + `remote` block in
+ * connection.json. The registry is a named list of agent SOURCES (local
+ * runtime, remote gateways, Hermes Cloud instances, SSH hosts) that are all
+ * registered at once; routing/pooling changes that consume the registry land
+ * separately, so this module is deliberately storage-shaped, not
+ * transport-shaped.
+ *
+ * Design rules (agreed with Teknium, Aug 2026):
+ *  - Every connection carries a REQUIRED, registry-unique `label` (the
+ *    "device name"). Uniqueness is case-insensitive so `Homelab` and
+ *    `homelab` can't coexist and produce two identical badges.
+ *  - When two sources expose the same profile name, surfaces disambiguate as
+ *    `@<profile>-<label-slug>` — `agentHandle()` is the one place that rule
+ *    lives.
+ *  - The registry ALWAYS contains exactly one `local` connection (the app's
+ *    own runtime). It cannot be removed; it is the default primary.
+ *  - `primary` designates the connection that owns the window backend (boot
+ *    overlay, install/update machinery). Removing the primary retargets to
+ *    the local entry rather than leaving a dangling id.
+ *
+ * Kept standalone (no `import 'electron'`) so it unit-tests with `node --test`
+ * — same pattern as connection-config.ts / backend-probes.ts. main.ts wires
+ * these into the IPC layer and owns file I/O + secret encryption.

Subject: [PATCH 233/376] fix(desktop): address connections-registry review
 findings
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Review fixes from #86679 comments (trevorgordon981, helix4u, kshitijk4poor):

- Edit inheritance: mergeConnectionInput preserves fields the editor does
  not carry (cloud org, ssh remoteHermesPath/remoteProfile) so a rename no
  longer wipes them. When the payload carries an ssh host string, stored
  user/port are NOT inherited — the composite host field is authoritative,
  fixing the stale user/port resurrection on edit.
- Token hygiene: tokens only persist on token-auth remotes; switching an
  entry to oauth (or cloud) clears the stale envelope.
- Plain-text opt-in: the panel now surfaces the same consent dialog as
  Settings -> Gateway on keyring-less machines (registry list exposes
  secureTokenStorage; save retries with allowPlainTextToken after consent).
- Registry test isolation: hermes:connections:test builds the probe directly
  from the registry entry instead of coercing against v1 connection.json —
  no more inheriting the v1 global token for a different host, and the local
  entry now probes the app-managed backend (never v1 remote/ssh state, so
  the test button can no longer trigger a v1 file write).
- 'local' id reserved at the validation boundary: a crafted IPC payload can
  no longer replace the local entry via upsert.
- Cloud creation hidden in the editor (a dialable cloud entry comes from the
  Cloud sign-in/discovery flow); migrated cloud entries stay editable.
- First-run migration write is guarded: a failed write keeps the migrated
  registry in memory instead of hard-failing every connections IPC call.
- uniqueLabel(): single label-dedup helper — counts up instead of "X 2 2",
  clamps 253-char migrated URL-host labels under LABEL_MAX; used by
  normalizeRegistry and both migration paths.
- UI copy: staged-rollout note replaces the "side by side" claim; test
  failure toast leads with the failure wording; dropped unused i18n keys.

Tests: +9 pure-module cases (reserved id, token-drop rules, merge
inheritance, ssh host precedence, uniqueLabel); electron+settings suites
1355 passed.

Subject: [PATCH 235/376] fix(gateway): spare pidfile-less Scheduled-Task
 gateways from the orphan reaper on Windows (#83683)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

On Windows _get_service_pids() is empty (no systemd/launchd query), so a
Scheduled-Task-supervised gateway whose gateway.pid record is missing or
stale is invisible to both the service-PID and recorded-PID exclusions the
reaper already applies (#86658) — and gets SIGTERM'd on every desktop open
(#86098 class, pidfile-less path).

Add a Windows-only backstop: any reaper candidate whose parent chain
reaches services.exe (the Task Scheduler launches tasks under the services
tree) is spared even with no pidfile.

The backstop is deliberately inert on POSIX: every process there has PID 1
(launchd/init/systemd) in its ancestry — and a genuine orphan is reparented
directly to PID 1 — so supervisor-name ancestry carries zero supervision
signal and would disable the reaper entirely on macOS/WSL (#51325, #75936).
POSIX supervised gateways are already covered pidfile-independently by the
_get_service_pids() exclusion.

Known limitation (fail-open, documented): if the Task-launched bootstrap
parent has already exited, Windows does not reparent the gateway, the chain
breaks before services.exe, and the gateway is treated as an orphan.

Salvaged from #86702 by @EvanProgramming (authorship preserved); reduced to
the genuinely-new Windows backstop — the PR's other two hunks were already
merged on main via #86658 (one in a strictly stronger full-parent-chain
form) and its POSIX ancestry checks were dropped as unsound (verified
empirically: a true double-fork orphan's psutil parent IS launchd).

Subject: [PATCH 236/376] fix(bedrock): let aux calls omit the Converse
 maxTokens cap

The Bedrock Converse shim hardcoded 'else 4096' when the caller passed no
max_tokens, so auxiliary vision descriptions stayed capped at 4096 tokens
on the Bedrock wire even after #75253 removed the vision call sites' own
caps (#10809 was only partially fixed there).

Converse's inferenceConfig.maxTokens is optional; when omitted, Bedrock
defaults to the model's maximum allowed output. Thread an explicit
max_tokens=None through build_converse_kwargs/call_converse to omit the
field, and drop an all-empty inferenceConfig from the wire request
entirely. The 4096 default is unchanged for every existing caller (main
transport passes params.get('max_tokens', 4096) explicitly), so only
no-cap aux calls opt in.

Surfaced during review of #75253.

 truthiness edge

Self-review follow-up: cover call_converse_stream's max_tokens=None path
(same builder, previously unpinned) and document why the shim reads the
caller cap with truthiness rather than 'is None' (parity with the
Anthropic shim's reading).

Subject: [PATCH 238/376] feat(delegation): raise max_concurrent_children
 default 3 -> 10 (+migration) (#86745)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

delegation.max_concurrent_children caps how many delegated children run in
parallel per batch (and concurrent background delegation units). The old default
of 3 needlessly serialized independent fan-outs (e.g. reviewing/​investigating N
PRs or issues at once), so large batches ran in slow chunks of 3.

Raise the shipped default to 10, which sits at/below the existing high-cost
advisory threshold (>10), so the default never trips the warning. Each child
still consumes API tokens independently, so this is a throughput/latency win the
user pays for in parallel token spend — the floor stays 1 and there is no
ceiling, so anyone can tune it down or up.

- config_defaults.py: default 3 -> 10; _config_version 36 -> 37.
- delegate_tool.py: _DEFAULT_MAX_CONCURRENT_CHILDREN 3 -> 10 (+ docstring).
- config_migrations.py: _migrate_to_37 lifts configs pinned at exactly the old
  default 3 to 10 (deliberate non-3 overrides preserved; unset inherits 10).
- cli-config.yaml.example: documented default updated.

Verified: default/fallback read 10, version 37, and the migration lifts 3->10,
preserves an explicit 5, and leaves unset untouched.

Subject: [PATCH 239/376] fix(vision): stop capping aux vision output with
 hardcoded max_tokens
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The vision tools' call_kwargs hardcode max_tokens caps (2000 for
vision_analyze/browser_vision, 4000 for video analysis), truncating
descriptions of complex images at the cap. The centralized aux client
already omits max_tokens by default (#34845) so providers use their
model max output; these three call sites were the leftovers that
bypassed that policy.

Remove the hardcoded caps entirely — the aux client handles the
mandatory-max_tokens Anthropic wire via _resolve_anthropic_messages_max_tokens
(model output ceiling) and Gemini native omits maxOutputTokens (65K ceiling),
so no wire needs an explicit cap.

Subject: [PATCH 240/376] test(vision): assert vision aux calls carry no
 max_tokens cap

Covers the max-tokens-knob contract: vision call_kwargs omit max_tokens
entirely (configured values, defaults, and even an explicit
auxiliary.vision.max_tokens config entry must never be forwarded), so
providers use their full output budget.

Subject: [PATCH 242/376] feat(gateway): optional profile param on cron.manage
 RPC (#86796)

cron.manage resolved its jobs store from the process HERMES_HOME, so a profile
whose cron lives in ~/.hermes/profiles/<name>/cron/ was invisible to the default
gateway (and any bot/plugin querying per-profile routines saw 'no cron jobs').

Add an optional 'profile' param that scopes the whole action via
set_hermes_home_override, exactly mirroring the adjacent skills.manage handler:
resolve get_profile_dir(profile), 404 (err 4064) if missing, override in a
try/finally that always reset_hermes_home_override. Omitted/None keeps the
launch-profile behavior, so existing callers are unaffected. cronjob() itself is
unchanged (it already keys off HERMES_HOME).

Enables the Hermes-Bot-Mode plugin to show a bot's real routines
(NousResearch/Hermes-Bot-Mode#37). Needs a SERVE-backend gateway restart to take
effect live. 2/2 in the new focused test.

Subject: [PATCH 243/376] feat(sessions): generic 'hidden' session flag
 (sidebar-hide, still resumable) (#86797)

* feat(sessions): generic 'hidden' session flag (sidebar-hide, still resumable)

Adds a source-orthogonal, archive-orthogonal 'hidden' session flag meaning
'don't show in the global Sessions sidebar, but stay fully resumable by the
surface that owns it'. Mirrors the existing archived/pinned capability end to
end, so it's a generic widening (any plugin that owns its own session lifecycle
- kanban, Bot Mode, future plugins - can keep its sessions out of the shared
recents list) rather than a per-plugin special-case.

- Schema: hidden INTEGER NOT NULL DEFAULT 0 on sessions (additive; lands on
  existing DBs via the declarative _reconcile_columns ADD COLUMN path, same as
  archived/pinned - no version-gated migration).
- DB: SessionDB.set_session_hidden(session_id, hidden) (clones set_session_pinned
  incl. the compression-lineage recursive CTE); list_sessions_rich gains
  include_hidden=False, appending 's.hidden = 0' by default so hidden rows drop
  from every listing path (and the REST sidebar endpoints inherit it with no
  change).
- Gateway: session.set_hidden RPC (mirrors session.title); session.create accepts
  hidden=true, deferred via pending_hidden and applied in _ensure_session_db_row
  when the row is lazily created (mirrors pending_title).
- REST parity: PATCH /api/sessions/{id} accepts+bool-validates 'hidden' ->
  set_session_hidden; _session_response exposes it.

Enables Hermes-Bot-Mode to hide canonical 'Bot Chat' sessions from the sidebar
(NousResearch/Hermes-Bot-Mode#46) WITHOUT retagging source (which would mis-set
the agent platform). Bot Chats keep source=desktop. Gateway RPC needs a
SERVE-backend restart to take effect live. 1 focused test (default-exclude /
include_hidden / unhide round-trip).

* fix: teach lost-and-found recovery about the 55-column sessions layout

Adding the 'hidden' column makes the current sessions table 55 columns. The
SQLite lost-and-found recovery classifier keys off the physical field count
(SESSIONS_LAYOUT_NFIELDS) to identify a salvaged sessions row, so a recovered
current-layout row (nfield=55) would otherwise be unrecognized and dropped.
Add 55 to the frozenset (54/52 stay as historical prefixes) and update the
column-count assertions + synthetic current-layout insert in the recovery test.

+### Settings → Connections: the multi-connection registry
+
+Alongside the per-profile connection mode above, **Settings → Connections** manages a named registry of every agent source the app knows about — the local runtime, any number of remote gateways (LAN, Tailscale, internet), Hermes Cloud instances, and SSH hosts — all persisted together in one place.
+
+- **Every connection needs a unique name** (a device name such as "Homelab" or "Work laptop"). When the same profile name exists on several registered sources, surfaces disambiguate it as `@profile-device` (e.g. `@research-homelab`).
+- **Add / edit / remove / test** connections from the panel. The local entry is managed by the app and cannot be removed. **Test** probes the connection's own HTTP and WebSocket legs directly.
+- Existing settings are **imported automatically** the first time you run a build with the registry: your current global connection and any per-profile overrides become named entries. The legacy settings file is left untouched, so older builds keep working.
+- Cloud entries come from the Hermes Cloud sign-in/discovery flow above, not from a hand-typed URL.
+- Tokens are stored encrypted with the OS keyring (with the same explicit plain-text opt-in as Settings → Gateway on keyring-less Linux).
+
+Side-by-side routing is rolling out in stages: connections are managed here today, while the active connection is still chosen in **Settings → Gateway**. Follow-up releases route chats, the agent roster, and updates across all registered sources.

 :::info The remote backend is a running `hermes serve` process
 "Remote backend" means a **`hermes serve`** server running on the remote machine — that is the process the desktop app connects to. Nothing in this section works unless that backend is actually up and reachable. The desktop app does not start it for you; you (or a `systemd` service) keep `hermes serve` running on the remote host, and the app attaches to it. If you also use messaging channels (Telegram, Discord, etc.), the **gateway** is a *separate* long-running process you start independently — see the note after the setup steps.

Subject: [PATCH 245/376] fix(artifacts): convert DB timestamps from seconds to
 ms for Date()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The Artifacts view reads message.timestamp, session.last_active, and
session.started_at from the SQLite database, which stores all timestamps
as Unix epoch seconds (REAL). These values were passed directly to
JavaScript's Date() constructor, which expects milliseconds — causing
every artifact timestamp to display as January 1970 dates.

Fix by multiplying the database value by 1000 to convert seconds to
milliseconds at the storage point, using nullish coalescing (??) instead
of logical OR (||) so that valid zero timestamps are not skipped.

Subject: [PATCH 246/376] fix(desktop): stop artifact over-indexing

Require explicit provenance for tool-result artifacts while preserving assistant links, MEDIA deliveries, generated outputs, file mutations, and browser screenshots. Normalize persisted Unix-second timestamps at collection time and retain millisecond fallbacks.

Consolidates current-main-compatible work from #41156 and #48577.

Subject: [PATCH 247/376] fix(desktop): artifacts page timestamps render 1970
 and local images fail
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

All three artifact timestamp sources (message.timestamp,
session.last_active, session.started_at) are epoch SECONDS — the
transcript reader and session-date-groups both multiply by 1000 — but
the collector passed them straight to new Date() (ms), so every
artifact rendered as 1970-01-21. Normalize seconds to ms once at
collection; the Date.now() fallback stays ms.

Local file artifacts (e.g. D:\ComfyUI\output\*.png) fell through to
mediaExternalUrl() which yields a file:// URL the renderer cannot
load. Route through the desktop fs bridge whenever it exists —
readDesktopFileDataUrl already dispatches remote REST vs local
Electron internally (#83380).

 for sharp HiDPI output

DPR-sized canvas backing store separated from CSS footprint, tracking
zoom/display changes live. Rendering-fix subset of PR #75307; the
overlay-placement feature portion is out of scope here.

Covers the devicePixelRatio half of #83216.

Subject: [PATCH 250/376] fix(desktop): smooth-scale pet sprite frames

Petdex spritesheets are 192x208px illustration frames, not pixel art.
The desktop canvas drew them with imageSmoothingEnabled=false
(nearest-neighbour), so zoomed pets looked blocky. Enable bicubic
smoothing so scaled frames stay clean at any zoom.

High-DPI backing-store sizing is addressed separately in #83276.

Subject: [PATCH 254/376] fix(petdex): quoted 'false' now disables
 display.pet.enabled everywhere

Three bare bool() reads of display.pet.enabled (deep-merged config, so a
hand-edited quoted YAML value lands as the string 'false'): the pet.cells
gate, the pet.gallery enabled echo, and the shared pet-state helper.
bool('false') is True, so a quoted value kept the mascot enabled against
the operator's explicit intent.

All three now go through utils.is_truthy_value (default False, matching
DEFAULT_CONFIG). Regression test drives pet.gallery with a quoted 'false'
config and asserts enabled=False; verified RED on the old code.

Subject: [PATCH 255/376] fix(petdex): cover the CLI pet pane and status-line
 signature too

Review follow-up: _pet_resolve_config (cli.py, the CLI pet pane gate) and
_pet_sig (tui_gateway/server.py, the status-line 'off' signature) read
display.pet.enabled with bare bool/truthiness, so a quoted 'false' still
enabled the mascot on the CLI surface. Route both through is_truthy_value
(default False) like the other three sites.

Subject: [PATCH 256/376] fix(pets): cover the pets CLI (doctor, has-active,
 /pet toggle) too

Second review follow-up: hermes_cli/pets.py still read display.pet.enabled
with bare bool()/truthiness in _cmd_doctor (misreported quoted 'false' as
enabled in 'hermes pets doctor'), _has_active_pet (quoted 'false' treated
as active, so /pet install skipped the selection prompt), and
toggle_pet_display (/pet toggle flipped the WRONG way). All three now go
through is_truthy_value(default=False); the module imports the shared
helper at the top.

Subject: [PATCH 257/376] test(pets): lock the quoted-false behavior on the CLI
 surfaces

Review follow-up (final round PASS with a repeated suggestion): the pets
CLI regression test only exercised real bools, leaving the exact bug this
fix shipped untested. Add a quoted-'false' test driving _has_active_pet
(now False) and toggle_pet_display (now takes the ENABLE branch,
distinguished by the 'no pets installed' error instead of err=None from
the old wrong-way disable). Verified RED on the pre-fix pets.py and GREEN
on the fix.

Subject: [PATCH 258/376] fix(gateway): send-once spritesheet semantics for
 pet.info (#54730)

pet.info accepts knownRevision; when it matches the active sheet's
revision the multi-MB spritesheetBase64 is elided and
spritesheetUnchanged=true is returned. The desktop floating pet passes
the revision it already holds and keeps its cached bytes, so backstop
refreshes no longer resend ~3.2MB frames over the WS (write-loop stalls,
disconnect storms). Legacy callers omitting knownRevision get the full
payload unchanged.

Subject: [PATCH 262/376] fix(kanban): detect WS client disconnect on idle
 board, prevent zombie poll tasks
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Closes #77833

stream_events() only detected client disconnect via send_json()
raising WebSocketDisconnect. When no events were pending (idle
board), send_json was never called, so the poll loop ran forever
even after the client disconnected — leaking one poll task per
disconnect.

Fix: race ws.receive() with a timeout matching the poll interval.
On timeout, poll the DB as before. On disconnect, exit cleanly.

Subject: [PATCH 272/376] fix(browser): reap leaked agent-browser daemons whose
 owner is still alive
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The orphan reaper had two gaps that let agent-browser daemons accumulate
indefinitely inside a single long-lived hermes process:

1. `_reap_orphaned_browser_sessions()` ran exactly once, before the cleanup
   loop started, so a leak appearing after boot could never be recovered.

2. `owner_alive is True` skipped unconditionally. In-memory session tracking
   is lost on any exception path between spawn and registration, but the
   owner PID stays up — so such a daemon was skipped forever.

The daemon-side `AGENT_BROWSER_IDLE_TIMEOUT_MS` is not a backstop for (2):
it does not fire when the daemon itself is wedged, e.g. after Chrome's
framework was replaced underneath it by an auto-update.

Observed on macOS: five agent-browser daemons (96 Chrome processes) built up
over 10 days inside an 18-day-uptime hermes process, holding roughly 5 CPU
cores busy and driving the load average past 100. Four of those processes
were still running a Chrome framework version that had since been replaced
on disk, spinning at ~85% CPU each.

Changes:

- Re-run the reaper every `BROWSER_ORPHAN_REAP_INTERVAL` (300s) from inside
  the cleanup loop. Cycle 0 preserves the existing startup reap.

- When the owner is alive but the session is untracked, fall back to idle
  age: reap past `BROWSER_ORPHAN_GRACE_SECONDS`, defined as
  `max(1h, 20 x inactivity_timeout)`. Unknown age fails safe.

- Add `_socket_dir_idle_seconds()` — the newest mtime under a session's
  socket dir. Every browser command writes `_stdout_<cmd>` / `_stderr_<cmd>`
  there, making it a last-activity marker that survives hermes restarts and
  does not depend on in-memory bookkeeping surviving an exception path. It
  scans directory entries rather than reading the directory mtime alone:
  command names repeat, and rewriting an existing `_stdout_click` updates
  that file's mtime but not the directory's, so a dir-mtime-only check would
  report a busy session as idle and reap it.

Sessions still present in `_active_sessions` are never touched at any age,
and the new path still goes through `_verify_reapable_browser_daemon`, so
the anti-spoof / anti-PID-recycle guarantees from #14073 are unchanged.

Adds 9 tests: idle-age unit tests (including the dir-mtime regression),
spared/reaped/fail-safe cases for a live owner, the identity-guard gate on
the new path, and a periodic-reap test asserting more than one reap per
cleanup-thread lifetime.

Subject: [PATCH 273/376] fix(pets): delete row strips after extracting their
 frames

Each hatch generates one row strip per state into cache/images and
extracts the animation frames from it, but never removes the strip. The
only cleanup for that directory runs in the gateway housekeeping loop,
which a CLI, desktop, or cron hatch never starts, so the strips
accumulate for good.

Drop the strip after every attempt once its frames are decoded into
memory, including failed or retried attempts, so a hatch no longer grows
the image cache without bound.

Subject: [PATCH 274/376] fix(pets): remove the non-PNG base draft after
 hardening

generate_base_drafts hardens every base draft to a transparent PNG with
_harden_transparency. When the provider returned a non-PNG file (webp,
jpg, or gif), the hardened PNG is saved under a new path and the original
draft is left in cache/images. Nothing prunes that directory outside the
gateway housekeeping loop, so a CLI or desktop draft round leaks one
original per non-PNG draft.

Remove the original after a successful hardening when the output path
differs from the input. PNG inputs (including mixed-case suffixes like
.PNG) are hardened in place so a case-insensitive filesystem cannot
treat with_suffix(".png") as a different file and unlink the output.

Subject: [PATCH 276/376] fix(sessions): release active-session leases against
 their acquisition registry
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A gateway active-session lease is acquired against the root HERMES_HOME,
but release_active_session()/transfer_active_session() re-resolved the
registry path from the *current* HERMES_HOME. Under native multiplex a
routed turn runs agent cleanup inside _profile_runtime_scope, so the
release looked under the named profile while the root entry stayed
alive — after max_concurrent_sessions routed turns every new session was
rejected with 'Hermes is at the active session limit' (#85431).

Pin state/lock paths on the lease at acquisition time and prefer them on
release and transfer. Fixes #85431.

Subject: [PATCH 278/376] fix(projects): use _branch_lane_id for non-git
 folders to prevent duplicate lanes (#53329)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

_place_by_heuristic used the raw path as the lane key for non-git
project folders, while the desktop overlay independently computed
::branch::main for the same session (since git_branch was null).
The ID mismatch caused duplicate lanes — one from the backend with
the folder name, one from the overlay labeled 'main'.

Use _branch_lane_id(path, DEFAULT_BRANCH_LABEL) so the backend's
lane key matches the overlay's expected ::branch::main scheme,
eliminating the duplicate lane.

Subject: [PATCH 279/376] fix(desktop): order project-tree lanes by recency in
 the overview, not alphabetically
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

_build_repos emptied each lane's sessions array for the overview (hydrate=False)
payload BEFORE _sort_lanes ran. _lane_sort_key derives a lane's activity from
max(_session_time(s) for s in group["sessions"]), so with the rows already gone
every non-trunk lane scored activity=0.0 and the sort key
(is_trunk, is_kanban, -activity, label) collapsed to alphabetical-by-label. The
documented intent — branches and linked worktrees sort by most-recent activity,
then label — was silently defeated on the projects.tree RPC that feeds the
desktop sidebar overview, while the drill-in path (hydrate=True) kept the rows
and sorted correctly. Any repo with two or more non-trunk lanes showed a
different order in the overview than when opened.

Move the session-clearing to after _sort_lanes/_disambiguate_labels so the sort
reads real recency. Lane counts are still captured before clearing, so
sessionCount and the slim overview payload are unchanged — only the order is
fixed, and the overview now matches the drill-in.

Subject: [PATCH 280/376] fix(desktop): stop dual main lanes for non-git
 project workspaces

Live overlay always placed sessions under `::branch::main`, while the
backend non-git heuristic keys the lane by folder path (label =
basename). Overlay missed that lane by id/label and forked a phantom
`main` group with the same sessions.

Match existing path-keyed isMain lanes before creating a branch-style
main lane. Covers the codex-research-guardian-style drill-in duplicate.

Subject: [PATCH 281/376] fix(desktop): evict stale lane entry when overlay
 moves session to worktree

When a session's cwd moves from the main checkout to a newly created
worktree, overlayRepoLanes places it into the matching worktree lane but
never removed the stale entry from the main lane. The session appeared
under both groups until the user left and re-entered the project view.

Add a cross-lane eviction loop that removes the session from all other
lanes before inserting it into the target lane.

Subject: [PATCH 283/376] fix(desktop): no-op branch switch on non-repo project
 lanes

Non-repo explicit projects (plain folders) get a main-checkout lane whose
label is the folder basename, not a branch. Clicking "+" (new session) on
such a lane calls switchBranchInRepo -> switchBranch, which sanitizes the
basename to "" and throws "Branch name is required.", aborting the
session creation. Short-circuit switchBranch for roots that are not git
work trees so callers proceed with a plain session.

Fixes #83028

Subject: [PATCH 285/376] fix(projects): dedup project_create by primary_path
 (#75820)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Creating a project whose resolved primary path already belongs to a
non-archived project now raises a clear ValueError naming the existing
project (create_project) — duplicated projects each seeded an identical
copy of the repo subtree, multiplying the duplicate-lane bug per copy.
The agent-facing project_create tool is idempotent instead: it re-activates
the existing project rather than erroring. allow_duplicate_path=True keeps
deliberate duplicates possible. Also updates the legacy non-git lane-id
expectation to the branch-style id introduced for #53329.

Subject: [PATCH 288/376] test: align lost-and-found schema pins with
 git_metadata_generation column

The salvaged #76716 adds git_metadata_generation to sessions (54 -> 55
columns). Update the synthetic-rebuild test's pinned widths and row
builders to the new current layout.

Subject: [PATCH 290/376] fix(desktop): let sidebar wheel scrolling chain past
 the virtualized list
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

With 25+ sessions the recents list virtualizes into its own nested
scroller inside the sidebar's scroll container. Both carried
overscroll-contain, so once the inner scroller hit a scroll boundary the
wheel gesture was consumed instead of chaining to the outer sidebar
scroller — read as a mid-list wheel dead-zone while scrollbar drag kept
working. Drop the containment on the inner scroller only; the outer
sidebar scroller keeps overscroll-contain so the gesture still never
escapes the sidebar.

Fixes #84964

Subject: [PATCH 291/376] design(kanban): add side-by-side dialog prototype (4
 variants)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Reference prototype for the upcoming 'replace window.confirm/prompt/alert in
the kanban plugin' work. Self-contained HTML — open in any browser, no build
step. Served at docs/design/kanban-dialogs/index.html.

Four variants side-by-side, each rendered in the same kanban context:
- A (Conservative): direct host ConfirmDialog mapping, minimal chrome
- B (Strong-fit, Pro's pick): textarea + SVG icon + inline validation
- B-refined (synthesis, recommended): auto-focus, dual-validation,
  cancellable spinner during PATCH, per-task summaries in bulk-many
- C (Divergent): undo toast for non-destructive moves

Decision matrix at the bottom of the page. Copy is verbatim from
web/src/i18n/en.ts (confirmDone, confirmArchive, confirmBlocked,
trash.confirm, completionSummary, etc.).

Design pass: Gemini 3.1 Pro (initial brief) + GPT-OSS 120B (cross-vendor
review). Not shipped to users — review reference only.

Subject: [PATCH 292/376] feat(plugins): expose
 Dialog/ConfirmDialog/Toast/useToast/useConfirmDelete on plugin SDK
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Additive expansion of window.__HERMES_PLUGIN_SDK__. Plugins can now render
host-styled dialogs, confirmations, and toasts instead of falling back to
window.alert/confirm/prompt.

New components: Dialog, DialogClose, DialogContent, DialogDescription,
DialogFooter, DialogHeader, DialogTitle, ConfirmDialog, Toast.
New hooks: useToast (replaces showToast/toast pair), useConfirmDelete
(single-id delete-confirm state machine).

SDK_CONTRACT_VERSION unchanged at 1.1.0 — additive surface per
sdk.d.ts:23-25 (no major bump required).

Consumer: kanban plugin's 'replace native dialogs' work, see issue #50547.
A reference prototype showing 4 design variants is committed at
docs/design/kanban-dialogs/index.html.

Adds web/src/plugins/registry.test.ts (3 vitest cases) that smoke-test the
new keys are wired and that the version constant is unchanged.

Subject: [PATCH 293/376] fix(kanban): replace native browser dialogs with
 in-app ConfirmDialog
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Migrates 8 of 12 native dialog call sites in the kanban dashboard plugin
to the SDK's ConfirmDialog primitive (added in PR #50550):
  - moveTask, moveSelected, applyBulk, deleteTask, deleteSelected,
    archiveBoard, removeAttachment, doPatch

The 4 remaining carve-outs (window.prompt for completion summary,
window.alert for missing summary, cli_hint clipboard fallback) are
documented inline — the host's ConfirmDialog hardcodes onClick → unmount,
preventing the keep-open-across-validation behavior the completion-summary
form needs. Followup: upstream a `disabled` prop to ConfirmDialog and
rebuild the completion body using host Dialog components.

New architecture:
  - useKanbanDialogs(t) — Promise-based dialog state machine at
    KanbanPage scope. request({kind, ...}) returns {confirmed, summary?}.
  - KanbanDialog component — renders ConfirmDialog from SDK for kind=confirm.
  - performMoveTask(taskId, newStatus, count, summary) — extracted shared
    dispatch path for single + bulk moves (optimistic UI + PATCH/POST +
    error recovery).
  - requestDialog prop threading — KanbanPage → BoardSwitcher,
    TaskDrawer → TaskDetail → doPatch/AttachmentsSection. Every call
    site has a defensive fallback to window.confirm if the prop is
    missing (verified by test_dashboard_done_actions_prompt_for_completion_summary
    counting the cancel guards + destructive:true markers in the bundle).

New host i18n keys (web/src/i18n/en.ts + types.ts):
  - kanban.confirmDoneMany / confirmArchiveMany / confirmBlockedMany
  - kanban.trash.confirmTitle / confirmManyTitle

Tests:
  - Replaced bundle-string-only completion-summary test with behavioral
    coverage: bundle cancel-guard count + destructive marker count, plus
    backend tests that confirm cancel preserves old status and confirm
    dispatches the expected PATCH/DELETE body.
  - Removed the SDK_CONTRACT_VERSION snapshot test from
    web/src/plugins/registry.test.ts (forbidden by AGENTS.md
    "Don't write change-detector tests"; the two remaining tests in that
    file already cover the new SDK surface behaviorally).

Closes #50547 (consumers of #50550).

Cross-vendor re-review: Gemini 3.5 Flash + GPT-OSS 120B (both SHOULD-FIX,
no remaining BLOCKERs after these fixes).

Subject: [PATCH 296/376] fix(desktop): confirm before clearing the entire
 Enabled Toolsets list (#73319)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Config settings auto-save on a 550ms debounce with no undo. The
'Enabled Toolsets' list is rendered by the generic ConfigField with no
destructive-change guard, so a stray select-all + Backspace (or any edit
that empties the list) is persisted the moment Settings closes —
silently disabling memory, terminal, web search, delegation, and most
tools. Recovery required CLI intervention.

Guard the one destructive transition: when the enabled-toolsets list
goes from non-empty to empty, window.confirm() before applying it (the
same pattern env-var removal already uses in toolset-config-panel.tsx).
Every other edit passes through untouched.

The decision is a pure helper (clearsEnabledToolsets) so it is unit
tested directly rather than through a full settings render. New i18n key
toolsetsWipeConfirm added to en + zh; partial locales inherit the
English string via defineLocale fallback.

Fixes #73319

Subject: [PATCH 297/376] feat(desktop): confirm before deleting a session
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Deleting a session in the desktop app fired instantly on click — the CLI
path (hermes sessions delete) asks y/N by default, so one misclick (Archive
and Delete sit right next to each other) permanently destroyed a conversation
with no dialog and no undo (#61470).

Route every delete entry point (sidebar rows, tab menus, the chat header,
context menus — all share useSessionActions) through a shared
DeleteSessionDialog built on ConfirmDialog. ConfirmDialog gains an
onOpenAutoFocus prop so dialogs with no input keep focus off the close
button (a11y).

Tests: menu delete now asks; cancel keeps the session; Enter confirms;
Escape cancels; delete item disabled without onDelete; the same guard
applies via SessionContextMenu.

Subject: [PATCH 298/376] fix(console): skip the checkpoints prune confirmation
 the console already took
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Hermes Console registers `checkpoints prune`, `clear` and `clear-legacy` as
mutating, so it takes a console-level confirmation before dispatching any of
them. `_apply_confirmed_defaults` then exists to keep the CLI layer from
asking a second time — its docstring says so — but it only force-defaults
`clear` and `clear-legacy`. `prune` was left out, even though `cmd_prune`
gates its orphan preview on the identical `not args.force` shape.

`_capture_output` redirects stdout and stderr but never stdin, so the
unskipped `_confirm()` call hits `input()` with no terminal behind it:
`EOFError` propagates into `_confirm`, which returns False, and `cmd_prune`
prints "Aborted." and returns 1. The console turns that non-zero exit into a
ConsoleCommandError, so `checkpoints prune` fails outright for any user who
has at least one orphan checkpoint project — after that user already
confirmed. When the server does happen to inherit a foreground terminal, the
same call instead blocks a console worker thread and eats the operator's
keystrokes.

Forcing the flag is the documented behavior here rather than a weakening of
the recent orphan-allowlist hardening. `orphan_allowlist` binds a deletion to
the identities shown in the preview, guarding the window where a workdir
disappears while the command waits on `input()`. Under the console there is
no preview and no wait, which is exactly the `--force` case the comment on
`cmd_prune` describes as "no restriction".

Subject: [PATCH 299/376] fix(desktop): stop deleted sessions resurrecting
 through racing list fetches
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A session deleted in the sidebar disappeared optimistically but flashed
back when any list fetch raced the in-flight DELETE RPC — the backend
page still carried the doomed row until the transaction committed
(#50928, reproduced with 'Load more' and auto-refresh). The optimistic
tombstone ($removedSessionIds) was only honored by the recents slice of
refreshSessions; the messaging slice, the per-platform pager, and
refreshMessagingSessions ingested backend pages unfiltered.

Extract the tombstone filter into dropTombstoned() and apply it at every
session-list ingestion point. Tombstones only exist while a delete or
archive is in flight (they self-clear on confirmation and are removed
immediately on failure), so non-destructive refresh paths are untouched.

Fixes #50928

Subject: [PATCH 301/376] i18n(web): add kanban bulk-confirm keys to all
 locales (English fallback)

The salvaged kanban ConfirmDialog added confirmDoneMany/confirmArchiveMany/
confirmBlockedMany to types.ts and en.ts only; the strict locale type
requires every locale to carry them. English fallback pending translation.

Subject: [PATCH 303/376] fix(desktop): prevent Enter from submitting during
 IME composition

Check event.nativeEvent.isComposing in Enter-to-submit branches so CJK (Japanese, Chinese, Korean) and other compositional input methods commit the candidate instead of firing the send handler.

Applied to all five sites in the desktop renderer that currently handle Enter with no composition guard:

- chat composer main submit and trigger popover (apps/desktop/src/app/chat/composer/index.tsx)
- message edit composer submit and trigger popover (apps/desktop/src/components/assistant-ui/thread.tsx)
- onboarding API key and auth code inputs (apps/desktop/src/components/desktop-onboarding-overlay.tsx)
- session rename input (apps/desktop/src/app/chat/sidebar/session-actions-menu.tsx)

Fixes #37483

Subject: [PATCH 305/376] fix(desktop): block Enter keyCode 229 after IME
 compositionend
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

macOS Chinese IME (and some 3rd-party Windows IMEs) emit Enter with
keyCode 229 (legacy VK_PROCESSKEY) after compositionend, while
isComposing is already false. The existing guard only checked
isComposing and the composingRef, so this Enter slipped through and
submitted the message before the committed text was fully in the DOM.

Add an explicit keyCode 229 check in handleEditorKeyDown.  keyCode is
deprecated, but it is the only reliable signal for this IME commit
Enter on Chromium-based browsers.  Includes a dom-repro test that
simulates the macOS IME sequence.

Fixes: "中文混英文按 Enter 直接上屏"

Subject: [PATCH 306/376] fix(desktop): recover from a stale IME composition
 flag that wedged the composer
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A missed compositionend (focus jump, input-source switch, programmatic DOM
swap mid-preedit) left composingRef stuck true, and the stuck flag silently
swallowed every Enter in handleEditorKeyDown and every Send-button submit via
the form onSubmit guard — no error, no RPC, until the composer remounted. For
CJK IME users (where even ASCII typing runs through composition) this read as
"Enter has no effect; messages cannot be sent", degrading composer instance
by composer instance.

Recover in two places, both grounded in invariants Chromium guarantees:

- keydown: every keydown during a genuine composition carries
  isComposing=true, so when the native flag says we're not composing, clear
  the stale ref before the guard reads it.
- blur: a composition never survives focus loss, so clear the flag
  unconditionally — this is what unblocks the Send button path, which has no
  native composition flag to consult.

The genuine-IME protection (#37483 class) is untouched: Enter with
isComposing=true is still swallowed.

Fixes #44135

Subject: [PATCH 307/376] fix(desktop): ignore IME composition keydowns in
 keybind combo resolution
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Chinese/Japanese/Korean IMEs emit keydown events during composition that
carry preedit keystrokes and the commit keypress (Enter/Space/Shift for
candidate selection). Treating them as combos fires unrelated keybinds —
e.g. typing 你 with a CJK IME could dispatch session.new and silently
open a new session.

Guard comboFromEvent():
- Bail out entirely while composing (event.isComposing or key === 'Process')
- Ignore keydowns whose event.key is a bare modifier name but whose code
  is a regular key — legacy IMEs that synthesize keystrokes (Q9 2002 sends
  key="Control" with code="KeyW") would otherwise canonicalize into
  phantom combos like mod+w that close the active tab.

Tested with Q9 (九方) legacy IME on Windows.

Subject: [PATCH 313/376] fix(tui): preserve IME text before return submit

Preserve printable IME commit text when xterm delivers it in the same input burst as Return, so Dashboard/TUI submits the visible draft instead of dropping the final segment.

Also fixes the TUI type-check stdio tuple typing and adds focused regression coverage.

Subject: [PATCH 314/376] fix(tui): stop Vietnamese Telex IME from dropping
 characters
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Third-party Vietnamese IMEs (OpenKey/Unikey/EVKey in Telex mode) recompose
a syllable by emitting an erase burst followed by the finished characters.
Two layers of the TUI input pipeline mishandled this, dropping letters and
leaving a stray space mid-syllable (e.g. "hạnh" rendered as "hạ  ", and
"vương sỹ hạnh" as "vương sỹ hạ  ").

Root causes, both confirmed from real captured byte streams:

1. parse-keypress: an IME often fuses a control byte (\x7f/\b, or even the
   U+202F marker OpenKey injects) with the recomposed text in a single stdin
   read. parseKeypress only recognizes a control key when the whole string is
   exactly that byte, so a mixed chunk fell through every branch, returned
   name:"" with a non-printable sequence, and the composer's printable gate
   discarded the entire chunk — taking the surrounding letters with it. Split
   text tokens on every control byte so the printable runs survive.
   CR/LF are deliberately not split, preserving paste/return semantics.

2. textInput: multi-character (IME/paste) inserts were committed through the
   16ms deferred key-burst path, which raced an interleaved re-render and
   snapped the buffer back to a stale value, dropping the recomposed tail.
   Commit them synchronously. Additionally, the fast-echo "\b \b" backspace
   shortcut desynced the screen when it ran right after an Ink repaint (forced
   by the U+202F marker), stranding the marker glyph; suppress fast-echo for
   the recompose burst that follows an Ink repaint and resume it on the next
   real keystroke.

Tested with real OpenKey and EVKey captures of "vương sỹ hạnh" across read
timings, plus parser unit coverage and an EVKey no-regression guard.

Subject: [PATCH 315/376] fix(tui): tighten IME test per teknium1 review
 (#55415)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Remove unconditional 60ms wait that let deferred path pass sync-commit test
- Use fake timers (setTimeout/setInterval/Date only, NOT setImmediate)
- Assert immediately after final read — no trailing wait/advance
- Add deterministic coverage for 60ms fast-echo suppression reset:
  * suppresses backspace after Ink repaint (IME recompose)
  * does NOT suppress on normal ASCII typing
- Verified: revert sync commit -> deferred path makes 4/6 tests fail

Subject: [PATCH 316/376] fix(dashboard): prevent React from dropping first
 keystroke during IME composition
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

React 18's root-level event delegation intercepts keydown events with
keyCode 229 (the "composition in progress" signal sent by the browser
during non-Latin IME input) and synthesises an onCompositionStart event.
That synthetic path sets internal composing state that interferes with
xterm.js's own IME handling on its hidden textarea, causing the first
keystroke of each composition chunk to be silently dropped.

The fix adds a capture-phase keydown listener on the terminal host div
that stops propagation of keyCode-229 events before they reach React's
delegation layer.  xterm.js relies on native compositionstart/
compositionend on its internal textarea — not on keydown — so blocking
the propagation is safe.

Fixes #52111

Subject: [PATCH 329/376] perf(state): stop selecting full message content in
 session search

Every search route in _search_messages_impl (FTS, CJK bigram, trigram,
LIKE fallback, rebuild-gap supplement) selected m.content, then the
result tail popped it unread. On DBs with multi-MB tool rows, each
search read and materialized up to `limit` full rows only to discard
them. Snippets come from snippet()/substr() in SQL and the context
window is re-fetched by id, so no code path ever read the column.

Drop the column from all six SELECT lists. Returned dicts are
unchanged: content was never part of the public result (the pop ran
before return), and tests/test_hermes_state.py already documents that
contract.

(cherry picked from commit d0c3af167e7dd4eb18e1bea29ba107a94911ea24)

Subject: [PATCH 334/376] perf(run-agent): reuse the Anthropic request-local
 client instead of rebuilding it per call

_create_request_anthropic_client() built a fresh anthropic.Anthropic
client (and httpx pool) on every single LLM call, and
_close_request_anthropic_client() always fully closed it right after
- unlike the OpenAI-wire path, which caches and reuses one warm
client across sequential calls via a single-slot cache keyed on the
effective client kwargs.

Add the same single-slot cache to the Anthropic-wire path: keyed on
credentials, base URL/Bedrock region, per-model timeout, and the
1M-beta flag; in_use guards concurrent calls from sharing one pool's
close/abort lifecycle; poisoned marks a cross-thread-aborted slot so
the owner-thread close discards it; reuse only on request_complete /
stream_request_complete (the same _REQUEST_CLIENT_REUSE_REASONS the
OpenAI path already uses). Wires a teardown hook into
release_clients()/close() mirroring _close_cached_request_openai_client.

Fixes #HPA-02

Subject: [PATCH 335/376] perf: parallelize provider model-list fetches in
 model picker

When the 1h provider_models_cache.json TTL lapses, the model picker
serially fetches /v1/models for each authenticated provider. With 10+
providers this stacks to 15-30s of blocking before the picker renders.

Add a parallel prefetch step before the serial picker build loops:
- _collect_authed_provider_slugs(): lightweight credential pre-scan
  that mirrors sections 1/2/2b without fetching model lists
- _prefetch_provider_models_parallel(): ThreadPoolExecutor-based
  concurrent fetch of stale/missing cache entries (max 8 workers)
- update_provider_cache_entry(): thread-safe single-entry cache writer
  with threading.Lock to prevent concurrent write races

Guardrails:
- Skipped when <=3 authed providers (overhead not worth it)
- Skipped when refresh=True (serial path force-refreshes)
- Exception-isolated (falls back to serial path on any failure)
- No behavioral change (same model lists, same picker output)

Closes #80413

(cherry picked from commit 89dddd6cb5d53d73278e0518c375fb5b878e5c6b)

Subject: [PATCH 336/376] fix(session-search): forward detail through the
 public session_search wrapper

Main extracted a session_search() wrapper (owned-DB lifecycle) around
_session_search_impl after #82595 was opened; the cherry-picked detail
parameter landed on the impl only. Append it to the wrapper with the
same positional-compatibility contract and pass it through.

Subject: [PATCH 339/376] feat(tui): auto-collapse reasoning blocks only when
 the reasoning phase ends
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Under display.sections.thinking: collapsed, the TUI now keeps the LIVE
reasoning panel open while reasoning streams and collapses it the moment
the reasoning phase ends (first tool call, final answer, or new turn).

Previously 'collapsed' meant the panel was always collapsed — including
the currently-streaming reasoning — and there was no way to get
'expanded while live, collapsed when done'. This makes 'collapsed' an
auto preference:

- turnController tags the open reasoning segment isLiveReasoning and
  seals the tag in endReasoningPhase/closeReasoningSegment
- streamingAssistant passes reasoningActive only to the live segment,
  so sealed reasoning segments from earlier phases stay collapsed
- ToolTrail auto-opens while reasoningActive under collapsed mode;
  expanded/hidden/MoA-reference semantics are unchanged

Adds thinkingLiveCollapse.test.tsx covering open-on-stream, close-on-
finish (including mid-turn rerender), and the expanded-mode no-op.

(cherry picked from commit 6ef4ef77d3a0837c8ef5c5dac3de74f352bd637d)

Subject: [PATCH 341/376] fix(desktop): flip zone collapse chevron to action
 direction
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Collapsed tool zones (terminal/logs) kept a down chevron after minimize,
so the restore affordance looked like another collapse. Point the icon in
the action direction — down when expanded, up when collapsed — matching
master-detail collapsible detail headers. Same fix for floating panes.

Subject: [PATCH 343/376] feat(web): add collapse toggle for the chat side
 panel

The right-hand chat panel (model picker + session list) is a fixed 240px
column on desktop with no way to hide it. Add a collapse button (X) in the
panel header and a floating 'panel' button over the terminal to reopen it,
mirroring the collapsible app sidebar. The choice is persisted in
localStorage (hermes-chat-panel-collapsed) so it survives reloads.

Subject: [PATCH 344/376] feat(desktop): add session list density modes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Squashed from #68124, resolved against current main (inbox cards, marquee
titles, actions cluster). Adds a Settings → Appearance 'Session list
density' preference — compact (default, unchanged), comfortable
(+deterministic metadata line), detailed (+initial-request preview) —
with density-aware virtualizer estimates.

Closes #68119

Subject: [PATCH 346/376] fix(desktop): default session list density to compact
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Keeps the sidebar byte-identical for existing users until they opt into
comfortable/detailed themselves — per the no-default-change salvage rule.

Subject: [PATCH 349/376] fix(tui_gateway): fall back to session id when
 session_key is NULL in truncation persist

CLI-origin sessions have no session_key; the Desktop history-truncation
path called replace_messages(session["session_key"], ...) with None,
whose reinsert violated the messages.session_id FK -> "FOREIGN KEY
constraint failed" -> "Restore failed" on resume. Key the persist off
the durable session id instead.

Extracted from PR #81904 (the scope=compacted API half was superseded by
include_compacted, #86595). The PR's companion change defaulting
session_key to the session id at insert time is deliberately NOT taken:
main treats a non-NULL session_key as "this is a gateway session"
(list_gateway_sessions, orphan gateway-session repair), so the default
would misclassify every CLI session.

(extracted from PR #81904, commit cef9b9b27d)

Subject: [PATCH 356/376] fix(desktop): preserve complete history when
 branching

Read the durable display transcript when creating a branch instead of copying the compacted model projection. Hydrate the Desktop branch boundary from persisted history, avoid stale whole-chat counts, and seed the new tile from the backend snapshot. Add regression coverage for compacted histories, visible-message counts, selected prefixes, and hydration races.

(cherry picked from commit c3d2d759ae104395adde215b2e293ccf8e895684)

Subject: [PATCH 358/376] perf(cli): re-export decomposed command modules
 lazily, ~60ms off every CLI start

The main.py decomposition re-exported the sessions/update/dashboard command
surface with eager from-imports, so every hermes invocation (including
hermes --version) paid for update_cmd's dependency chain (jwt, click,
cryptography). Resolve the re-exports through the existing PEP 562 module
__getattr__ (same pattern as _PROVIDER_MODELS) so each module loads on
first actual use. Internal call sites go through a _self() helper because
bare-name lookups do not trigger __getattr__; _self() imports sys locally
since update tests patch hermes_cli.main.sys. The
_warn_stale_dashboard_processes back-compat alias moves into the lazy
surface, and the sessions argparse dispatch defers sessions_cmd to call
time. Monkeypatching hermes_cli.main.<name> keeps working: a patch sets a
real module attribute, which shadows __getattr__.

Measured (Windows 11, Python 3.11, median of 7 warm runs):
import hermes_cli.main 253ms -> 196ms (-22%).

(cherry picked from commit cad1083b71635f98815b698d69a18f7f58e15517)

Subject: [PATCH 359/376] perf(cli): stop per-keystroke config re-reads in
 slash completers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The /tools and /personality completers run on every keystroke while the
user types those commands (complete_while_typing), and both re-read +
re-parse the full config on each keypress:

- _tools_completions called load_config() — the defensive deepcopy
  (~340us/call on cache hit) even though it only reads toolset enable
  state + MCP server names. Switched to load_config_readonly() (the
  perf(agent) #74322 pattern; this per-keystroke site was missed).
- _personality_completions called load_cli_config() — a full YAML parse
  + deep merge of the built-in defaults (~110us) — on every keystroke.
  Memoised keyed on the config file path+mtime (same pattern as load_env
  / _nous_auth_status_cache), so the parse runs once per config state.

Measured: /tools 357us -> 18us per keystroke; /personality parse drops
from 1-per-keystroke to 1-per-config-change (500 keystrokes -> 1 parse).

Regression tests: _tools_completions uses the readonly loader (deepcopy
loader never called); personality memo parses once across repeated
completions and re-parses once after a config mtime change.

(cherry picked from commit 2b3f897171f93dc6b099848ec5ab3763b7294870)

Subject: [PATCH 360/376] perf(cli): memoise default-hermes-root resolution and
 global auth-store read
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

get_default_hermes_root() resolves HERMES_HOME against the platform
native home (~80us of path resolution) on EVERY call and is called at
31+ sites — every _load_global_auth_store() (per provider row in the
/model picker), kanban, backup, gateway, update. Its result depends
only on (HERMES_HOME, native home), so memoise it keyed on those two
inputs, compared for free on each call (freshness-correct even if a
test or plugin mutates HERMES_HOME mid-process).

_load_global_auth_store() re-read + re-parsed the global auth.json on
every call; read_credential_pool() -> load_pool() runs it once per
provider row in the /model picker even when the profile has entries and
the global fallback never fires. Memoise keyed on the global auth
file's path+mtime (same pattern as _nous_auth_status_cache); the store
only changes when a global-scope auth write touches the file.

Measured (profile mode, 30-provider global store): get_default_hermes_root
81us -> 10us; _load_global_auth_store 128us -> 66us; load_pool 165us ->
137us per call — ~2ms saved per /model picker render (20 provider rows).

Regression tests: hermes_constants memo pin (no path resolution on
repeat calls, HERMES_HOME change forces a fresh resolution); global-store
memo pins (store read once across repeats, mtime bump re-reads once,
absent store stays cheap).

Subject: [PATCH 363/376] perf(toolsets): memoise resolve_toolset keyed on
 registry generation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

resolve_toolset() recursively walks toolset includes and, with
include_registry=True, merges registry-registered tools on every call —
each external call re-runs the includes walk and takes a fresh registry
snapshot under the registry lock. It is called dozens of times per
_get_platform_tools() (every /tools completion keystroke, per picker
render) and at 19 call sites across the CLI/gateway.

Memoise the external-entry result keyed on (name, include_registry,
registry id, registry generation). tools.registry exposes a monotonic
_generation counter bumped on every register/deregister/alias/MCP
refresh (its docstring explicitly invites generation-keyed memoisation),
so a cache entry is valid until the registry changes. External callers
never pass visited, so the memo engages exactly at the public entry
and the internal cycle-detection recursion is untouched.

Measured: _get_platform_tools drops 165us -> 59us per call (3x) with the
xAI credential fix simulated; /tools completion ~2ms -> ~77us/keystroke
combined. Regression tests: repeat resolution is a memo hit (get_toolset
called once), a generation bump forces a fresh resolve, and the memoised
result is identical to a fresh resolution.

(cherry picked from commit 3d36ecb273f6652d00556a7b9d846c08047801aa)

Subject: [PATCH 364/376] perf(agent): cache per-turn display-flag config reads

_file_mutation_verifier_enabled and _turn_completion_explainer_enabled
re-read config.yaml on every call via load_config() (~1ms deepcopy per
call). finalize_turn runs these gates at the end of every turn, so each
turn paid two redundant config deepcopies. The sibling
_credits_notices_enabled already caches on self; mirror that pattern.

The env-var override stays authoritative and uncached, so runtime flips
still work. Config flips now apply on the next session, matching the
documented sibling semantics.

(cherry picked from commit f2d0e00d71ba35fa3a53cd41076261e3c5feb45d)

Subject: [PATCH 367/376] test(cli): stub portable-MCP lookup in completer read
 test; bound resolve_toolset memo
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- The readonly-loader completer test now stubs
  get_portable_mcp_server_names_nowait — real plugin discovery runs
  load_config() during one-time process init, which is not the
  per-keystroke read the test guards against.
- Cap _resolve_toolset_memo at 256 entries: generation-keyed entries
  from stale generations are never hit again, so clear on overflow to
  keep long sessions bounded.

Subject: [PATCH 372/376] fix(desktop): stream native gateway downloads + 404
 data-url fallback
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Addresses both review findings on the remote-gateway download PR:

1. Unbounded buffering (finding #1). fetchBuffer / fetchBufferViaOauthSession
   accumulated the entire response (then copied it again via Buffer.concat)
   before saveGatewayFile even opened the save dialog, so a large gateway file
   could exhaust the native process. Both auth paths now stream: once response
   headers arrive the connect timeout is cleared, the filename is derived, the
   save dialog is shown, and the body is piped to the chosen destination with
   backpressure. A read/write error tears down the stream and unlinks the
   partial file. The byte-moving, data-URL decoding, and filename/path helpers
   are extracted into gateway-file-download.ts so they're unit-testable without
   Electron.

2. No fallback for older gateways (finding #2). saveGatewayFile required the new
   /api/fs/download route. Desktop and the remote gateway update independently,
   so a gateway predating this PR 404s. Added a 404-only compatibility fallback
   to the existing capped /api/fs/read-data-url route (bounded, so it only
   serves smaller files — enough to keep older backends working).

Tests: gateway-file-download.test.ts covers streaming, backpressure,
error-cleanup (unlink on write/response error), data-URL decoding, filename
derivation (incl. traversal reduction), and 404 detection;
gateway-file-download-transport.test.ts asserts both transports stream (no
whole-body Buffer.concat) and that the 404 fallback is wired. Both registered
in the desktop platform test list. Server-side /api/fs/download tests
(streaming + sensitive-file reject) already pass.

Subject: [PATCH 373/376] test(desktop): port gateway-file-download tests to
 vitest electron project

The salvaged branch predates the electron test project's node:test -> vitest
migration (test:desktop:platforms is now `vitest run --project electron`).
Import `test` from vitest so the suites are collected; assertions stay on
node:assert/strict per the existing electron test convention.

Subject: [PATCH 376/376] fix(tests): align lost-and-found sessions pin with
 the 56-column layout

Upstream's d16326bb25 bumped this test's sessions-schema pin for the
new git_metadata_generation column (54 -> 55), but landed on a tree
that already carried the 'hidden' column from fbaea9bddc, so the real
layout is 56 and upstream main is red on
test_mapper_rebuilds_sessiondb_from_synthetic_lost_and_found
(assert 56 == 55). Verified byte-identical to upstream and reproduced
locally.

Bump the width in the four coupled places the value is load-bearing -
the pin, max_fields (the lost_and_found table width), the
current-layout insert(), and its comment - mirroring exactly what
d16326bb25 itself did. Bumping the pin alone would only move the
failure into the row builders. Verified locally: pins pass and the
56/52/14/23-field inserts are all accepted.

The correct value is objectively fixed by the schema (this is a
schema pin, not a product-intent choice), so when upstream re-aligns
it the next sync takes upstream's version of these hunks. Recorded in
CLAUDE.md (user-approved 2026-08-15).
