Deferred upstream sync — refreshed to current upstream tip

This PR carries the accumulated upstream sync for the OpenTUI fork. It has been
refreshed again to the current upstream tip — the live sid/opentui branch
is now 463 commits behind upstream; this branch contains all of them, merged,
plus the live branch's own V4A diff-render fix, and the engine gate is green.

Status: the merge into this branch is complete (the prior CLI-entry conflict
stays resolved additively; this refresh added one real tui_gateway/server.py
conflict in the /title handler, resolved by unifying on the shared
session.info emit — see below) and the full OpenTUI engine gate passes —
857 engine tests green, dist/main.js builds, the tui_gateway/server.py
test module is 310 green
. This batch is held for a human decision; the
live sid/opentui branch is left untouched and keeps running.

What changed in this refresh

  • Merged the live branch's own one commit (the V4A hunk-less diff-render fix)
    into this branch first, so the refreshed batch is a true descendant of live.
  • Merged the latest upstream delta (10 commits) on top: a /timestamps command
    • timestamps in /history, Ctrl+G submits the edited draft (TUI parity), the
      email-pairing opt-in pair, a Nous-auth idle-refresh fix, telegram group-doc
      caching, accept any inbound file type across messaging platforms, bridge
      docker_extra_args to the terminal env in CLI + gateway, dashboard
      chat-session-title fix, and an s6-overlay v3 dashboard-role detection fix.
  • None of the 10 new commits touch ui-opentui/ — they are pure
    CLI / gateway / platform / container surface.

Conflict resolved in this refresh (/title handler)

tui_gateway/server.py's session.title handler had three spots where both
sides changed the same lines: the fork emitted a post-title refresh via
_emit_title_refresh(sid) (added for the OpenTUI terminal window-title chrome),
while upstream's dashboard-title fix emitted via
_emit_session_info_for_session(sid, session). Both helpers ultimately emit
the identical session.info event
(_emit("session.info", sid, _session_info(agent, session))); they differ only in how they obtain the
session dict (_emit_title_refresh re-fetches by sid and silently skips if the
sid isn't a live _sessions key; _emit_session_info_for_session uses the
session already in hand). In this handler the session is already resolved and
valid, so the resolution unifies all three call sites on
_emit_session_info_for_session — strictly more robust, consistent with the two
non-conflicting sibling call sites in the same handler, and the OpenTUI
window-title chrome is preserved
(the engine consumes the session.info
event, not a distinct one — confirmed in ui-opentui/src/boundary/schema/SessionInfo.ts).
The fork's _emit_title_refresh helper stays defined and is still used on the
auto-title worker-thread path (its original purpose); its unit test is kept. The
matching test conflict was resolved by keeping the fork's superset
test_session_info_includes_session_title (DB-wins + pending + None coverage)
and dropping upstream's duplicate-named subset.

The prior hermes_cli/main.py additive conflict (fork's OpenTUI
engine-selection block vs upstream's Windows ui-tui workspace auto-restore
helpers, empty merge base, both sides only adding disjoint functions) remains
resolved by keeping both function sets.

Why this is still deferred (not auto-advanced)

  1. Core agent-loop contract / cache-risk changes (always-defer surface).
    The batch touches the cache- and alternation-sensitive core of the agent
    loop across ~51 commits, where an auto-merge could silently degrade a running
    session: the non-retryable error-summary / content-policy path, provider
    failover (identity-in-sync, persistent-401/403 failover, auth-failure abort),
    finalize-turn cleanup guarding, token-calibration reset on model switch,
    context-aware tool-output budget scaling, the full compression-rotation /
    in-place-compaction cluster, stripping stale reasoning_content when falling
    back to a strict provider, preserving copilot routed headers, treating an
    empty-content summary response as a failure, owned-SQLite-session
    finalization on agent close (with the background-review fork opted out),
    routing the repeated-compression warning through the status emitter, broader
    Authorization / x-api-key header redaction, and the cache-safe late-binding
    MCP tool-refresh work (multi-round adversarial-review hardening). These are
    held for review, never auto-advanced.

  2. Unported TUI / gateway features. Multiple Ink-side and gateway-contract
    changes have no mirror yet in the OpenTUI engine and need a real port (not a
    thin pass-through), including: /reasoning full, /prompt ($EDITOR compose),
    /compress before/after summary, /timestamps + timestamps in /history,
    Ctrl+G draft submit, pending-input commands routed via command dispatch,
    persist model switch across sessions, honor managed-config scope in
    standalone config loaders, expose late-connecting MCP tools to the agent,
    hide sidecar sessions from history, tmux fast-echo / cursor-drift fixes, the
    hosted-mode update guard, a failed in-place model swap being a no-op, and
    persisting session messages on force-quit / signal shutdown.

    These are Solid + @opentui/core engine work, too large/ambiguous to port
    blindly under the auto-merge bar.

What needs a decision

  • Whether the core agent-loop changes are safe to take onto the live engine
    (review the failover / error-summary / content-policy / finalize-turn /
    token-calibration / reasoning-strip / copilot-header / compression /
    session-finalization diffs).
  • Port (or sign off on porting) the TUI/gateway features above into
    ui-opentui/src/view/ and ui-opentui/src/boundary/.

Once the ports land and the core changes are accepted, this branch can be
fast-forwarded onto sid/opentui. The branch builds and tests green as-is; the
hold is about feature-port completeness and core-contract review, not a broken
tree.


Added in this push: Part A + Part B planning docs

This branch now also carries two planning deliverables under docs/handoffs/:

  • opentui-part-a-advance-live.md — the plan to advance sid/opentui to this batch:
    core accepted as upstream-hardened; gateway / MCP / in-place-compaction / session-finalization
    scrutinized and adapted into the OpenTUI engine; a split gate (advance on the regression surface,
    port net-new features after). Includes a 3-reviewer adversarial-review record (merge-strategy,
    ripple-completeness, simplicity lenses) with all findings applied + verified against the tree.
  • opentui-part-b-gateway-tui-feature-ports.md — the gateway/Ink-TUI feature-port backlog
    (12 features classified by real port difficulty, with file:line anchors and the governing
    OpenTUI skills), to be implemented separately.

Part A code change landed on this branch (2026-06-22)

fix(opentui): make /reload-mcp actually rebuild the live agent's tools (commit cad2b149d) —
the OpenTUI TUI's /reload-mcp was a silent no-op (dead hasattr(agent, "reload_mcp_tools")
branch in _mirror_slash_side_effects; that method never exists). Now routes through the same
shutdown_mcp_servers() → discover_mcp_tools() → refresh_agent_mcp_tools() sequence as the working
reload.mcp RPC, and adds reload-mcp to the running-turn guard (the tool snapshot is part of the
cached tools= prefix). 3 adversarial-review rounds + /simplify; engine 857 + tui_gateway 310 green.

Part A's other scrutiny items resolved to NO code change (premises verified against the tree):

  • Sidecar filter — non-bug: sidecar sessions use source: "tool" (already deny-listed); no
    "sidecar" source label exists. Adding one would be dead code.
  • Session finalization — composes correctly via end_session first-reason-wins; no double-finalize.
  • In-place compactioncompression.in_place defaults off; engine reads session.info.compressions
    (already decoded). No schema/engine change to advance (ON-by-default is a separate decision).
  • fast-echo-tmux — N/A: the OpenTUI input has no fast-echo bypass.

Part B (the 12 gateway/Ink-TUI feature ports) remains to be implemented separately per its handoff.

…o strict providers

Per-message timestamp metadata injected by _apply_persist_user_message_override
leaks into the Chat Completions payload sent to the provider. Strict OpenAI-compatible
providers (e.g. Fireworks-backed endpoints like OpenCode Go 'glm-5.2', Mistral, Kimi)
reject this schema-foreign field with HTTP 400:

  Extra inputs are not permitted, field: 'messages[0].timestamp'

The ChatCompletionsTransport.convert_messages already strips known internal-only
fields (tool_name, _-prefixed scaffolding keys, codex_reasoning_items, etc.) — add
timestamp to that list.

Closes NousResearch#47868
Add a regression test for NousResearch#47868 asserting convert_messages strips the
internal per-message timestamp field, plus the identity-return path for
timestamp-free message lists. Map x7peeps for the release attribution gate.
In Docker the install tree (/opt/hermes) is read-only, so npm install for
the WhatsApp bridge fails with EACCES. Add resolve_whatsapp_bridge_dir() in
whatsapp_common.py: when the install dir is read-only, mirror the bridge
source into a writable HERMES_HOME location and use that. Both the
adapter and the 'hermes whatsapp' CLI resolve through the shared helper so
the install and runtime paths agree.

Fixes NousResearch#49561
Follow-up for salvaged NousResearch#49654: unit tests for resolve_whatsapp_bridge_dir()
(writable passthrough, read-only mirror, existing-mirror reuse) and the
AUTHOR_MAP entry for the contributor.
…aram (NousResearch#49854)

The kanban-worker skill taught kanban_complete with three full examples but
never mentioned the artifacts=[...] parameter added in NousResearch#27813 — so a worker
reading the skill had no way to learn it can ship a chart/PDF/image as a
native upload to the subscriber's chat.

Adds a 'Shipping deliverables' section covering absolute-path rules, the
inline-vs-file extension behavior, and the trap that the notifier reads the
top-level artifacts list (NOT metadata.*).
The dispatcher treated workspace_kind=worktree as metadata only and never
ran 'git worktree add', so every worktree task ran in the main repo checkout
instead of an isolated worktree — concurrent tasks silently shared one tree
and contaminated each other.

This materializes a real linked worktree at <repo>/.worktrees/<task_id> on
branch wt/<task_id> when resolve_workspace() handles a worktree task, treats a
repo-root workspace_path as shorthand for that location, persists the derived
workspace/branch back onto the task row, and — on rerun/redispatch — detects an
already-materialized linked worktree (via git-common-dir) and reuses it instead
of nesting a second .worktrees/<id> inside it.
Follow-up to the salvaged worktree-materialization fix. When a worktree
task has no explicit workspace_path, resolve the anchor from the board's
default_workdir (a git repo) and materialize <repo>/.worktrees/<id> per
task, instead of silently rooting under the dispatcher's CWD (whatever
directory launched the gateway, e.g. the Hermes checkout). If no
default_workdir is configured, raise with a clear message rather than
guessing from CWD.

Adds AUTHOR_MAP entry for the salvaged commit.
On Windows, hermes writes writer.bat (@echo off / hermes -p writer %*)
with CRLF endings instead of the POSIX writer shell script. The test
hardcoded the POSIX path and exact bytes, so it failed on Windows hosts.
Assert on stripped non-empty lines per platform, making it line-ending-
and OS-independent.
…ousResearch#49890)

doctor's npm audit hardcoded PROJECT_ROOT/scripts/whatsapp-bridge. In
read-only Docker installs the bridge deps live in the writable HERMES_HOME
mirror (NousResearch#49561), so node_modules was never found there and the bridge audit
silently skipped. Resolve the dir through the shared
resolve_whatsapp_bridge_dir() helper so doctor audits where deps actually
install. Falls back to the install-tree path if the helper is unavailable.
…ng them

When the agent is busy and the user sends multiple text follow-ups, the
interrupt-mode and steer-fallback path stored them via
merge_pending_message_event(merge_text=True), which newline-joins
consecutive TEXT messages into a SINGLE pending turn — collapsing two
separate user messages into one mashed-together turn and destroying the
message boundaries the user sees (NousResearch#43066 sub-bug 2).

Route that storage through _queue_or_replace_pending_event (the same FIFO
infrastructure used by busy queue-mode and /queue) so each follow-up gets
its own next-turn slot in arrival order, while still preserving
photo-burst / album merge semantics for media. Pure queue-mode already
used FIFO; this brings the interrupt/steer-fallback path in line.

The sibling defect in NousResearch#43066 (assistant messages lost after compaction)
was already fixed on main by the identity-tracking flush rewrite (NousResearch#46053)
plus the pre-rotation flush (NousResearch#47202), so this only addresses the
remaining busy-message-merge half.

… call

The subagent-demotion busy-handler test asserted the internal
merge_pending_message_event call, which the FIFO refactor replaced with
_queue_or_replace_pending_event. Assert the behavioral outcome (the
follow-up lands in the pending slot for the next turn) instead — same
fix already applied to the two steer-fallback tests.
…s rotation

Three state-loss bugs at the compression rotation boundary, fixed together
because they all live in the same ~80-line rotation block:

- NousResearch#33618: a persistent /goal did not follow the rotation. load_goal does a
  flat per-session lookup with no lineage walk, so a goal silently died when
  compression minted a fresh child id. Added migrate_goal_to_session() and
  call it after the child session is created (move-not-copy: the parent row
  is archived as cleared so exactly one active goal row exists).

- NousResearch#33906/NousResearch#33907: if the child create_session raised (FK constraint,
  contended write), the outer handler only warned and let the agent continue
  on the NEW id — which has no row in state.db — producing an orphan session.
  Now the rotation rolls agent.session_id back to the still-indexed parent
  (reopening it) instead of stranding the conversation on a phantom id.

- NousResearch#27633: the compaction-boundary on_session_start notification omitted the
  platform kwarg, so context-engine plugins saw source=unknown for every
  message after the boundary. Forward platform (matching the initial
  session-start call in agent_init.py).

The bundled himalaya skill and its website docs documented command
syntax that does not match Himalaya CLI v1.2.0.

Verified against pimalaya/himalaya v1.2.0 source:
- message move: MessageMoveCommand declares target_folder BEFORE
  envelopes (src/email/message/command/move.rs) -> usage is
  '<TARGET> <ID>...', so 'move 42 "Archive"' is wrong; correct is
  'move "Archive" 42'.
- message copy: same ordering in copy.rs.
- attachment download: AttachmentDownloadCommand exposes the flag as
  '-d, --downloads-dir <PATH>' (src/email/message/attachment/command/
  download.rs), not '--dir'.

Fixed in all three surfaces that carried the wrong examples:

- website/i18n/zh-Hans/.../email-himalaya.md
…tive PowerShell

The Chinese README still told Windows users to install WSL2 and run
the Linux installer. Hermes now ships a native PowerShell install
script, so replace the outdated WSL2-only note with the direct
PowerShell one-liner.

CONTRIBUTING.md had no pre-work search step; the only duplicate-check is a

Add a "Before You Start: Search First" section near the top so contributors

bug existed in slack, whatsapp, and telegram adapters (migrated from
gateway/platforms/ in 5600105): each inserts parents[2] = plugins/ onto
sys.path[0], shadowing the real cron/ package with plugins/cron/ so
'import cron.scheduler_provider' raises ModuleNotFoundError on gateway start.

Plugins shelling out to bare `hermes` via the terminal tool hit
`command not found` (exit 127) when the gateway was launched without the
hermes install dir on PATH (systemd, service managers, cron, desktop
launchers) — even though `hermes` works in the user's own interactive
terminal, which sources the shell rc that exports that dir.

The terminal tool's subshell PATH was the agent process PATH plus a
static set of system dirs (_SANE_PATH); it never included wherever the
hermes console-script actually lives (~/.local/bin, the venv bin/Scripts,
pipx, nix). Resolve that dir once (which/argv0/sys.executable) and
prepend-if-missing it so bare `hermes` resolves regardless of launch
method.
NousResearch#50499)

* feat(cli): /reasoning full to show complete thinking, not 10-line clamp

The post-response Reasoning recap box hard-clamped long thinking to the
first 10 lines, so there was no way to see the full reasoning trace after
a turn (live streaming already shows it in full). Add display.reasoning_full
(default off) plus /reasoning full|clamp to toggle it at runtime; the clamp
truncation note now points at the command. Addresses repeated user requests
to show all thinking tokens.

* test(gateway): de-snapshot /reasoning help assertion

The test froze the exact args-hint literal '/reasoning [level|show|hide]',
which the new full/clamp args change to '[level|show|hide|full|clamp]'.
Convert to an invariant: assert /reasoning is in help and carries its core
args, not the exact hint string.

* feat(tui): /reasoning full|clamp parity in tui_gateway

The classic-CLI reasoning_full toggle had no TUI equivalent — typing
/reasoning full in the TUI fell through to parse_reasoning_effort and
errored. The TUI renders thinking as an expand/collapse section (no fixed
10-line recap), so map full -> sections.thinking=expanded (raw, uncapped
via thinkingPreview mode='full') and clamp -> collapsed, persisting
display.reasoning_full for cross-surface config consistency.
…h#50509)

* feat(cli): /prompt — compose your next prompt in $EDITOR

Adds /prompt (alias /compose): opens $VISUAL/$EDITOR on a temp markdown
file so you can hand-edit a multi-line prompt, then sends the saved buffer
as the next agent turn. Text after the command pre-seeds the buffer; an
empty save cancels. Reuses the one-shot _pending_agent_seed the interactive
loop already consumes (same mechanism as /blueprint), so no changes to the
input event loop or message pipeline. CLI-only.

* feat(tui): /prompt slash command opens $EDITOR (parity with CLI)

The TUI already opens $EDITOR via Ctrl+G (openEditor), but had no /prompt
slash command like the classic CLI. Wire openEditor into the slash handler
context and register /prompt (alias /compose) to call it; inline text after
the command is dropped into the composer first so it carries into the editor,
matching the CLI's /prompt <text>.

When `hermes dashboard --host 0.0.0.0` is run interactively with the auth
gate engaged but no DashboardAuthProvider configured, prompt to set up the
bundled username/password provider on the spot (or point at `hermes dashboard
register` for OAuth) instead of only emitting the fail-closed error.

- main.py: `_maybe_setup_dashboard_auth_interactively()` runs before
  start_server. No-ops on loopback binds, when a provider is already
  registered, or when stdin/stdout isn't a TTY (Docker/s6, CI, piped runs) so
  the fail-closed SystemExit stays the backstop for unattended deploys. On the
  password path it writes dashboard.basic_auth.{username,password_hash,secret}
  to config.yaml (scrypt hash, never plaintext), then force-rediscovers
  plugins so the basic provider registers before the gate check.
- web_server.py: fix the fail-closed hint — it told operators to set
  `dashboard_auth.basic.username` but the provider reads `dashboard.basic_auth`.
- docs: note the interactive setup under Fail-closed semantics.

No new env vars; reuses the existing dashboard.basic_auth config surface.

* fix(gateway): walk /proc/*/cmdline to find main-wrapper.sh under s6-overlay v3 (NousResearch#49196)

(cherry picked from commit 3a108c2)

* fix(container): peel s6-v3 rc.init prefix so dashboard role is detected

kyssta-exe's preceding commit (NousResearch#49238) fixed _read_container_argv() to
locate the rc.init-launched main-wrapper.sh process under s6-overlay v3,
but the skip still never fired: _strip_container_argv_prefix() only peeled
a prefix when args[0] was init/main-wrapper.sh/hermes. Under s6 v3 the
matched argv is

    /bin/sh -e /run/s6/basedir/scripts/rc.init top
        /opt/hermes/docker/main-wrapper.sh dashboard ...

so args[0] stayed /bin/sh, _is_dashboard_container() returned False, and
the dashboard container reconciled + started its own gateway-default —
the exact dual Telegram getUpdates 409 in issue NousResearch#49196.

Fix: strip everything up to and including the main-wrapper.sh token (the
stable boundary the image owns), covering both the v2 (/init ...) and v3
(/bin/sh ... rc.init top ...) shapes with one rule, instead of matching
launcher tokens positionally. This also repairs _is_legacy_gateway_run_request()
under v3, which shares the same strip helper (the issue called this out).

Tests: extend the dashboard true/false parametrize sets with the s6-v3
argv shape, and add test_main_skips_reconcile_in_dashboard_container_s6v3
exercising main() end-to-end with the v3 argv. Verified via mutation that
both new v3 assertions fail under the old positional strip and pass with
the fix.

… in CLI + gateway (NousResearch#50631)

terminal.docker_extra_args passes flags verbatim to `docker run` (e.g.
--gpus=all, --shm-size=16g). It was wired into DEFAULT_CONFIG,
TERMINAL_CONFIG_ENV_MAP (so `hermes config set` bridged it),
terminal_tool._get_env_config (reads TERMINAL_DOCKER_EXTRA_ARGS), and
DockerEnvironment (applies extra_args) -- but it was MISSING from cli.py's
env_mappings and gateway/run.py's _terminal_env_map.

Consequence: a user who hand-edits config.yaml (rather than running
`hermes config set`) has docker_extra_args silently dropped on the CLI and
gateway/desktop startup paths, while docker_image / docker_volumes (which
ARE in those maps) bridge correctly -- producing the reported 'Hermes
partially reads the Docker config' symptom where --gpus=all and
--shm-size=16g never reach docker run.

This is the same bridge-coverage bug class that shipped before for
docker_run_as_host_user (cli + gateway) and docker_mount_cwd_to_workspace
(gateway). Fix by adding the key to both maps, plus a dedicated regression
pin in test_terminal_config_env_sync.py mirroring the existing
test_docker_*_is_bridged_everywhere guards.

Authorization to message the agent is the gate, not the file extension.
Previously the inbound-attachment allowlist (SUPPORTED_DOCUMENT_TYPES) was
opt-OUT on Discord (allow_any_attachment defaulted false) and had no bypass
at all on Telegram/Slack — so an .html (or any non-allowlisted type) was
dropped or hard-rejected before the agent saw it.

Now every authorized upload is cached and surfaced to the agent regardless
of type:
- base.cache_media_bytes(): unknown types cache as octet-stream (or the
  caller-supplied MIME) instead of returning None — fixes the chokepoint
  that Teams/Telegram-media route through.
- discord/telegram/slack adapters: removed the allowlist reject/skip; any
  non-media attachment is typed DOCUMENT and cached. Known types keep their
  precise MIME.
- Text inlining now gates on a shared _TEXT_INJECT_EXTENSIONS set (text +
  code + config + markup) instead of a blind UTF-8 decode, so binary formats
  (PDF/zip/docx) with ASCII headers are never inlined.
- gateway/run.py emits the path-pointing context note for every DOCUMENT,
  including non text/application MIME types.
- discord.allow_any_attachment is now a documented no-op kept for config
  back-compat.

Validation: 357 gateway tests pass; E2E confirms .html/.bin/custom types
cache, known types stay precise, PDFs are not inlined.
Follow-up to the accept-any-file-type change. The observe-unmentioned and
replied-media paths relied on cache_media_bytes() returning None for
unsupported document types to emit an 'unsupported, not cached' note. Now
that any file type is always cached, those docs are cached and surfaced with
a path-pointing note — consistent with the main document path. The
remaining cached-is-None branch is image-validation-failure only; its note
is reworded accordingly. Updates the group-gating test to the new contract.
…Research#50560)

Ctrl+G already opened $EDITOR with the current draft, but used
open_in_editor(validate_and_handle=False), which only loaded the saved text
back into the input area — the user still had to press Enter. The TUI's
Ctrl+G (openEditor) submits the draft on a clean exit. Since CLI submission
is driven by the custom Enter keybinding (not the buffer accept_handler),
validate_and_handle can't route through it; instead chain a done-callback on
the editor Task that calls the new _submit_editor_buffer(), which mirrors the
Enter handler's idle/queue/slash branches and drops an empty save.
…#50506)

display.timestamps already drove the [HH:MM] suffix on live submitted and
streamed message labels, but there was no runtime command to toggle it and
/history ignored the setting entirely. Add /timestamps [on|off|status]
(alias /ts) and render [HH:MM] in /history for turns that carry a stored
unix timestamp (resumed sessions). Live unsaved turns without a stored time
are never given a fabricated one. Uses the existing sanctioned non-wire
'timestamp' message key (stripped before the API call in chat_completions),
so message-alternation and prompt-cache invariants are untouched.

…s on the OpenTUI TUI

_mirror_slash_side_effects (the slash.exec route the OpenTUI engine uses for
every slash command) had a DEAD /reload-mcp branch: it gated on
hasattr(agent, 'reload_mcp_tools'), a method that is never defined anywhere,
so the branch was always skipped. The status bar flipped to 'MCP loaded' but
the live agent's frozen tool snapshot was never rebuilt -> the agent then
answered 'Tool mcp_... does not exist'. (Ink uses the dedicated reload.mcp RPC
and was unaffected.)

Fix: route the branch through the SAME full sequence the working reload.mcp RPC
uses, in the gateway process:
  shutdown_mcp_servers() -> discover_mcp_tools() -> refresh_agent_mcp_tools(agent,
  enabled_override=_load_enabled_toolsets(), quiet_mode=True) -> emit session.info.
The first two calls are load-bearing: refresh_agent_mcp_tools only READS the
in-process registry, so without mutating it first the rebuild is a no-op. The
slash command's own shutdown/discover run in the _SlashWorker SUBPROCESS,
invisible to the gateway agent.

Also add 'reload-mcp' to _MUTATES_WHILE_RUNNING: the rebuilt tool snapshot is
part of the request's tools= prefix, so rebuilding mid-turn would race the
worker and break the prompt cache. The busy-guard rejects it mid-turn, so the
rebuild only runs at an idle (cache-safe) moment. The confirm-gate divergence
from the RPC (no second cache-invalidation prompt on the slash path) is
documented inline as an accepted difference.

Verified: engine gate green (857), tui_gateway server tests green (310),
mcp-reload gateway tests green (3). 3 adversarial review rounds + /simplify.
Part A plan: correct §6c (sidecar is a non-bug — sessions use source='tool',
already deny-listed; no 'sidecar' label exists) plus the execution amendments.

Part B handoff: add §9 'How to work these tasks' — the proven controller +
subagent + adversarial-review(/simplify) loop from the Part A session: how to
classify verify-only vs port, the spike-first method, the delegate_task dispatch
recipe, the Claude Code review gate (no-subagent-fanout, round-over-round
convergence), the /simplify tmux safety, the premise-verification lesson that
saved 3 dead-code commits, the controller todo structure, and the pre-existing
tui_gateway test-ordering flake to expect.
…lid engine (Part B)

Two Part-B feature ports into the OpenTUI (Solid) TUI engine, plus the Part B
execution-findings record.

/timestamps [on|off|status] (alias /ts):
- Message.timestamp (unix seconds, the non-wire key) + a `timestamps` display
  flag; stamped on submit / stream-start; carried through mapResumeHistory
  (omitted, never fabricated, when a resumed entry lacks one).
- Glyph-based engine has no role labels, so [HH:MM] renders as a muted prefix
  on the body's first line (kept OUT of copied/wire text). timestampsCmd mirrors
  compactCmd; /timestamps + /ts in the CLIENT map + help.

/reasoning full|clamp:
- A reasoning-specific `reasoningFull` display flag that expands ALL thinking
  sections independently of the global /details mode (override() click still
  wins). reasoningCmd: bare = config.get sync, full/all + clamp/collapse/short
  local + config.set persist, any other arg (effort/show/hide) re-dispatched to
  the gateway via slash.exec.
- server config.get key=reasoning now returns reasoning_full (additive,
  read-only) so bare /reasoning can sync the persisted pref.

Tests: +timestamps.test.ts, +reasoning.test.tsx, both SlashContext test fakes
updated. Gate: 873 vitest (57 files) + 310 tui_gateway py green; build clean.

Deferred to a follow-up issue: /prompt + Ctrl+G $EDITOR compose (the engine has
no editor opener; feasible via @opentui/core suspend()/resume()).

…, /topup, terminal-billing UX) (NousResearch#51639)

* feat(tui): rename /billing slash command to /topup

Behavior-preserving rename of the /billing command surface to /topup.
Changes: billing.ts → topup.ts (export topupCommands, name 'topup', new
help string), registry.ts import+spread updated, billingOverlay.tsx
overview header 'Usage credits' → 'Top up credits', billingCommand.test.ts
→ topupCommand.test.ts with import/lookup/call updated. RPC method names
(billing.state, billing.charge, etc.) and component/symbol names unchanged.

* refactor(tui): extract overlay primitives to shared module

Lift MenuRow, ActionRow, footer, and barCells() out of billingOverlay.tsx
into overlayPrimitives.tsx so the upcoming subscriptionOverlay.tsx can
import them instead of duplicating. spendBar now calls barCells() —
output is byte-identical. Pure behavior-preserving refactor.

* feat(tui): add /subscription + /topup CTAs to /usage output

Every /usage render now ends with 'Run /subscription to change plan
· /topup to add credits' — both the healthy (with-calls) and depleted
(no-calls) paths. Strings-only change, no WS1 dependency.

* feat(tui): add subscription wire types

Add SubscriptionTierOption, SubscriptionStateResponse, and
SubscriptionManageLinkResponse to gatewayTypes.ts. Type-only — no
usages yet. Mirrors the BillingStateResponse conventions (snake_case,
Decimals as strings) and reuses BillingErrorPayload for error mapping.

* feat(gateway): add subscription.state + subscription.manage_link RPCs

- agent/subscription_view.py: SubscriptionState dataclass + fail-open
  build_subscription_state() (mirrors billing_view pattern) +
  get_subscription_manage_link() for the Stripe deep-link.
- hermes_cli/nous_billing.py: get_subscription_state() +
  post_subscription_manage_link() HTTP helpers for the two NAS endpoints
  (WS1 Phase A/C). The manage-link endpoint raises BillingScopeRequired
  when Remote-Spending is missing (Phase 4 step-up trigger).
- tui_gateway/server.py: _serialize_subscription_state() +
  subscription.state RPC (fail-open) + subscription.manage_link RPC
  (returns {ok,kind,url} or typed error envelope via
  _serialize_billing_error). NOT added to _LONG_HANDLERS — synchronous
  HTTP round-trip, not a device flow.

* feat(tui): add subscription overlay state types + store slot

Add SubscriptionScreen, SubscriptionOverlayCtx, SubscriptionOverlayState
to interfaces.ts and a 'subscription' slot to OverlayState. Wire it into
overlayStore.ts (buildOverlayState + $isBlocked). NOT added to
resetFlowOverlays preserve list — flow-scoped like billing, drops on
turn end.

* feat(tui): build SubscriptionOverlay — overview + confirm + handoff

Pure-render Ink component mirroring billingOverlay.tsx's structure.
Overview screen covers all 5 states (free-upgradeable, mid-tier,
top-tier, not-admin, downgrade-pending) + dunning. Confirm screen is
y/n deep-link to Stripe (NO in-terminal charge). Handoff is the
transient 'Opening Stripe' screen. Imports shared primitives from
overlayPrimitives.tsx. 8 render tests via renderSync covering every
state.

* feat(tui): add /subscription command + overlay wiring

- subscription.ts: SubscriptionOverlayCtx closure (openManageLink,
  refreshState, requestRemoteSpending) + run handler that fetches
  subscription.state and opens the overlay. Alias /upgrade.
- registry.ts: spread subscriptionCommands into SLASH_COMMANDS.
- appOverlays.tsx: render SubscriptionOverlay when overlay.subscription set.
- useInputHandlers.ts: Esc closes subscription overlay; promptOverlay OR
  includes subscription so input is intercepted while open.
- subscriptionCommand.test.ts: 4 tests (fetch+open, logged-out sys line,
  /upgrade alias, /subscription resolves).

* fix(tui/subscription): stop saying Stripe in deep-link copy + fix manage link kind type

Replace all user-facing 'Stripe' mentions in the /subscription overlay and
sys messages with 'your subscription page' — the deep-link target is NAS's
own /manage-subscription page, not the Stripe hosted portal. Stripe only
legitimately appears later at actual Checkout. Also add 'manage' to the
SubscriptionManageLinkResponse.kind union (NAS emits kind:'manage'; was
previously missing from the TypeScript type causing silent narrowing errors).

* feat(tui/subscription): render cancellation-scheduled note with headline precedence

Parse cancelAtPeriodEnd + cancellationEffectiveAt from the NAS contract
(camelCase) in the agent parser (_parse_current), emit cancel_at_period_end
+ cancellation_effective_at from the gateway serializer, extend the
SubscriptionStateResponse type, and render a warn note in OverviewScreen:
'Cancels on {date} — your plan stays active until then.'

Headline precedence when multiple flags co-occur:
  past-due > cancel-scheduled > downgrade-pending > active
The downgradeNote guard is tightened to suppress when cancel is scheduled,
so at most one status line renders at a time.

* feat(tui/subscription): team-context screen — redirect to /topup for team orgs

Parse the NAS context:'personal'|'team' field (defaults to 'personal' for
unknown/missing values), emit it on the gateway wire, add it to
SubscriptionStateResponse. When context is 'team', SubscriptionOverlay
renders a dedicated read-only screen instead of the tier picker:

  'This terminal is connected to {org_name}. Teams run on shared
   credits — use /topup to add funds. Personal subscriptions live
   on your personal account.'

The screen closes on Enter or Esc. The personal/tier-picker path is
unchanged.

* fix(subscription): drop manage-link gateway RPC, build URL locally

The NAS POST /api/billing/subscription/manage-link endpoint was dropped
(it added no server work — the target is the static /manage-subscription
page, not a Stripe-minted secret). Build the URL client-side instead:
{portal_base}/manage-subscription?org_id=<org.id>.

- Remove subscription.manage_link gateway RPC (server.py)
- Remove get_subscription_manage_link helper (subscription_view.py)
- Remove post_subscription_manage_link (nous_billing.py)
- Remove SubscriptionManageLinkResponse type (gatewayTypes.ts)
- Add org_id to SubscriptionState + wire through serializer + TS type
- openManageLink() builds the URL locally via buildManageUrl(), opens
  it with the existing openExternalUrl(), no gateway round-trip
- Drop targetTierId param from openManageLink (v1 sends everyone to
  /manage-subscription; no tier deep-link needed)
- Fix stale test expectations (Stripe copy → subscription page copy)

* chore(subscription): drop unused format_money import

* feat(cli): /subscription + /upgrade, /billing→/topup rename, /usage CTAs

Add the classic-CLI half of the terminal billing surface to match the TUI:
- /subscription (alias /upgrade) command + /topup (renamed /billing, keeps
  'billing' as a back-compat alias) in the command registry.
- Drop the stale 'billing' entry from _SLACK_VIA_HERMES_ONLY (now cli_only).

* feat(subscription): CLI /subscription handler, drop dunning, current:null no-plan

- CLI _show_subscription mirrors the TUI overlay (plan read + tier list + usage
  bar + browser deep-link via subscription_manage_url); credits render as counts.
- Adapt to the updated NAS read contract: remove is_past_due/dunning everywhere
  (a card-failing subscriber returns as a normal plan now), and treat no-plan as
  current:null (parser returns None) rather than an all-null object.
- HERMES_DEV_SUBSCRIPTION_FIXTURE env-driven fixtures + ui-tui fixture harness
  drive every state (CLI + live TUI) with no portal.

Verified against handoff 2026-06-24_subscription-tui-handoff.md.

* feat(billing): CF-4 Remote-Spending revoked-terminal UX (NAS PR NousResearch#481)

Wire the Remote-Spending gate denial contract end to end:
- nous_billing: BillingRemoteSpendingRevoked (403 remote_spending_revoked →
  reconnect) + BillingSessionRevoked (401 session_revoked → re-login), distinct
  from insufficient_scope; capture actor/code/recovery; 503 stays transient.
- gateway _serialize_billing_error threads the new typed kinds + actor/code/
  recovery to the TUI.
- TUI renderBillingError: actor-aware revoke copy, kills the spend overlay
  immediately (no 15-min zombie button), handles session_revoked, the dual-
  emitted cli_billing_disabled/remote_spending_disabled, role_required,
  idempotency_conflict; poll treats a mid-poll revoke as ambiguous (check
  balance before retry), not a failure.
- CLI _billing_render_charge_error: same denial matrix, actor-aware copy.

Tests: gate-contract mapping + envelope (py) and revoke/session/disabled (TUI).
Per handoff 2026-06-24_remote-spending-TUI-contract-handoff.md.

* refactor(subscription): remove dead step-up scaffolding from /subscription

/subscription only opens a browser deep-link to manage-subscription — that needs
no billing scope, so it can never hit insufficient_scope. Drop the never-fired
'stepup' screen type, requestRemoteSpending ctx fn, and resumeScreen bookkeeping
(leftovers from a superseded plan). The resumable step-up lives on /topup, where
the charge actually gets gated.

* feat(tui/topup): resumable 'Allow Remote Spending' step-up on the charge path

Phase 4: when a charge returns insufficient_scope, the /topup modal no longer
tears down with a 'run /billing again' ConfirmReq. Instead it stays MOUNTED and
switches to a step-up screen:
- charge() is now awaitable, returning a discriminated outcome (submitted |
  needs_remote_spending | error) so the overlay can route without closing.
- StepUpScreen: 'Allow Remote Spending' → await the device-flow grant (browser
  opens via the existing out-of-band billing.step_up.verification event) →
  replay the held charge (pendingCharge.amount) and settle, with no command
  re-run. Never surfaces the raw billing:manage scope.
- armStepUp's fire-and-forget ConfirmReq replaced by requestRemoteSpending();
  the leaky 'billing:manage' / 'Re-authorize' / 'run /billing again' copy is gone.

Tests: charge-outcome routing, step-up grant/deny, and a render test asserting
the step-up copy holds the amount and never leaks billing:manage.
Per handoff 2026-06-24_remote-spending-TUI-contract-handoff.md §2 (Grady #6).

* feat(billing): shared dollar usage model + two-bar view (drop "credits")

Single source of truth for the /usage and /subscription usage bars across
TUI + CLI. Reads the NAS account-info dollar fields (subscription/top-up/total
remaining, monthly allowance, renewal) and produces a surface-agnostic model:
two full-resolution bars (plan allowance + purchased top-up), a status
classification (free | healthy | low | depleted), and a human renewal date.

- agent/billing_usage.py: UsageModel/UsageBar, usage_model_from_account
  (fail-open), build_usage_model (HERMES_DEV_CREDITS_FIXTURE-aware),
  format_renews (ISO -> "Jul 24, 2026", Windows-safe), $5 low-balance threshold.
- tui_gateway/server.py: _serialize_usage_model/_serialize_usage_bar, a
  usage.bars RPC, and the model embedded into subscription.state so the overlay
  renders the same bars from its single fetch.
- Dollars only, never "credits"; two separate bars (not a crammed
  three-segment one) for legibility at terminal widths.
- tests/agent/test_billing_usage.py: status classification, bar math
  (clamp/over-cap), NaN/Inf rejection, fail-open invariants.

* feat(tui): dollar usage bars on /usage + /subscription, drop tier picker

Render the shared two-bar dollar model in both overlays; strip "credits" and
the in-terminal tier selection per UX feedback.

- overlayPrimitives.tsx: UsageBars (themed plan/top-up bars — gold allowance,
  green top-up) + usageBarsText for the /usage panel. Plan name labels the
  bar; "$X left of $Y · N% used" (disambiguated so the % matches); top-up
  "never expires".
- subscriptionOverlay.tsx: status line dedupes ($X left once; bar carries the
  breakdown), human renewal date, state-matched nudges (free upsell / <$5
  low alert) with box-safe ASCII markers (! / >) instead of the width-unstable
  emoji that broke the border. Tier picker removed — overview shows usage +
  plan, then "Manage on portal" / "Close" (free users get "Start a
  subscription"). No "credits" anywhere.
- session.ts: /usage renders the dollar bars + balance summary, falling back
  to the legacy credits lines only when the model is unavailable; CTA reworded.
- gatewayTypes.ts: UsageModelData/UsageBarData wire types + usage on
  SessionUsageResponse/SubscriptionStateResponse.
- Tests updated to the new contract (no "credits", "left of", dedup, markers).

* feat(cli): mirror dollar usage bars on /usage + /subscription

CLI parity with the TUI billing rework, from the same shared usage model.

- _print_nous_credits_block (/usage) and _subscription_overview render the
  two-bar dollar view (plan name on the bar, "$X left of $Y · N% used",
  top-up "never expires", total spendable) instead of the credits-worded block.
- Dollars only — dropped the tier catalog (no more "$N/mo (… credits)") and
  every user-facing "credits"; team copy says "shared balance".
- Human renewal date via the shared format_renews; status line dedupes the
  "$X left"; free upsell + <$5 low alert with ASCII markers.
- /subscription manage modal no longer dumps the raw manage-subscription URL
  in its detail — the [1] Open / [2] Copy link / [3] Cancel options carry it.
  Title is "Manage your subscription" (no in-terminal plan change). The raw URL
  stays only in the non-interactive / not-admin fallbacks, which have no menu.
- /usage token-usage panel (model, tokens, cost, context) left untouched.

* feat(billing): embed dollar usage model into billing.state for /topup

The /topup overview renders the same two-bar dollar usage (plan + top-up) as
/usage and /subscription. Embed the shared usage model into the billing.state
RPC payload (mirrors subscription.state) so the overlay gets the bars from its
single fetch, and add the `usage` field to BillingStateResponse.

* feat(tui/topup): reorder overview + in-flight reauth with press-Enter resume

Reworks the /topup overlay per the Jun 19 review and the no-preflight decision.

Overview:
- Balance leads in the title ("Top up · balance $X"); the shared two-bar dollar
  usage (plan + top-up) renders below. Dropped the old monthly-cap spend bar.
- "Add funds" is the first action (was "Buy credits"); auto-reload / monthly
  limit / manage-on-portal follow. Dollars only — no "credits" anywhere.
- No "Enable terminal billing" menu item and NO scope preflight: whether the
  terminal can charge is discovered reactively at pay time. (We deliberately do
  not read/refresh the OAuth token to gate UI.)

Step-up (reached only on a charge's insufficient_scope 403):
- New 4-phase flow that keeps the modal mounted: prompt (one-time-setup
  heads-up) → waiting (browser authorize) → granted (explicit "Press Enter to
  resume") → replay the held charge → settle. The press-Enter beat is the
  reassuring "you're back, finish your purchase" moment.
- Renamed user copy "Allow Remote Spending" → "Enable terminal billing"; never
  leaks the raw billing:manage scope (guarded by the render test).
- topup.ts error copy de-crufted to terminal-billing wording, emoji removed.

Tests: step-up prompt copy, the no-raw-scope invariant, and new overview tests
(balance-in-title, Add-funds-first, two-bar usage, no "credits").

* feat(cli/topup): mirror overview reorder + in-flight reauth resume

CLI parity with the TUI /topup rehaul, from the same shared usage model.

- _billing_overview: balance in the title, the two-bar dollar usage (plan name
  on the plan bar, top-up "never expires") in place of the old cap spend bar,
  "Add funds" first, dollars throughout — no "credits", no scope preflight.
- _billing_handle_scope_required: now takes the held amount + idempotency key
  and runs the in-flight flow — "Enable terminal billing" → browser device-flow
  → re-check the org kill-switch → press-Enter to resume → replay the held
  charge (reusing the key so a double-submit collapses to one). Stops leaking
  the raw billing:manage scope.
- Charge-error + buy/auto-reload copy de-crufted to terminal-billing/dollars.
- Tests updated to the new overview + buy copy.

* fix(billing): guard non-JSON 2xx responses in the billing HTTP client

A 2xx response with a non-JSON body — e.g. a reverse-proxy / SPA fallback HTML
page served when a billing route isn't actually mounted on a deployment — hit
json.loads() on the success path of _request() and raised a raw
json.JSONDecodeError. That escaped the typed-BillingError contract, so callers'
`except BillingError` missed it and fell through to a generic fail-open that
rendered as a misleading "not logged in" (observed when /api/billing/subscription
was briefly unshipped on staging: 200 text/html, x-matched-path /[...notFound]).

Now a non-JSON 2xx body raises a typed BillingError(error="endpoint_unavailable")
so surfaces degrade gracefully ("could not load …") instead of crashing or
mislabeling a valid session as logged-out. The 4xx/5xx path already guarded its
.json(); this closes the same hole on the success path.

Test: tests/hermes_cli/test_nous_billing_request.py — non-JSON 2xx → typed
error (not JSONDecodeError, not BillingAuthError), empty body → {}, valid JSON
parses.

* feat(billing/dev): add HERMES_DEV_BILLING_FIXTURE for offline card/scope testing

build_billing_state short-circuits to a fixture when HERMES_DEV_BILLING_FIXTURE
is set (mirrors HERMES_DEV_CREDITS_FIXTURE for the usage model). States:
nocard | card | card-autoreload | notadmin | billing-off | logged-out — so the
card-on-file gate, admin role, and kill-switch paths are exercisable offline
without a live portal. Env-var gated; returns None when unset (no prod leak).

Adds 8 behavior tests asserting the card/admin/billing-on contract per state.

* refactor(billing): fold /credits into /topup

/credits is redundant now that /topup shows the dollar balance + portal handoff.
Make 'credits' (and 'billing') aliases of /topup so typing /credits still works,
resolving to topup everywhere (CLI, gateway, Slack, TUI, autocomplete, help).

Remove the standalone /credits surface across 6 places:
- CLI _show_credits handler + dispatch
- gateway _handle_credits_command -> renamed _handle_topup_command, copy softened
  to 'Manage billing on the portal' (the messaging billing surface; /topup is now
  gateway-available so messaging keeps billing — credits was the only one before)
- TUI commands/credits.ts + creditsCommand.test.ts (deleted), registry entry
- tui_gateway credits.view RPC + the CreditsViewResponse type
- Slack _SLACK_VIA_HERMES_ONLY: credits -> topup

Sweep user-facing /credits -> /topup (usage-block hint, depletion notice) and
stale doc-comments. OpenRouter's /credits endpoint URL left untouched. Tests
updated (test_credits_folds_into_topup) or pruned for the removed symbols.

* fix(billing): card-on-file heads-up, no-card portal gate, /usage bar ordering, modal glyph

In-terminal charge (POST /charge against the org's server-held card, no card ref
leaves the client):
- card present: confirm screen shows 'Your card saved on the portal will be
  charged' + a 'Manage on portal' escape option (CLI); heads-up line (TUI)
- no card on file: /topup overview + buy flow detect it and route to the portal
  to add a card, instead of offering a charge that 403s no_payment_method

/usage bar ordering: route the dollar block through _cprint consistently. The
Plan: line (_cprint) and the bar (raw print) flushed to different buffers under
patch_stdout and interleaved nondeterministically; now Plan: -> bar -> status/CTA
is stable across all states.

Modal glyph: strip the leading emoji from bordered _prompt_text_input_modal
titles — it measures 1 char but renders 2 columns, shifting the box's right
border (the stray '|'). Includes the f-string 'Pay $X?' title.

Small /credits -> /topup string bits in cli.py ride along with the surrounding
charge edits (the fold lives in the sibling refactor commit).

* refactor(billing): apply safe simplify-pass fixes

Three low-risk cleanups from a parallel simplify review (reuse/quality/efficiency):
- dev fixture portal URL: reuse the prod host (was drifted to staging-* — a real
  mismatch vs subscription_view's _DEV_FIXTURE_PORTAL)
- TUI billingOverlay choose(): collapse two byte-identical branches (needsCard +
  the not-full else both = portal-or-close at index 0) into one tail; the only
  divergent path (full && !needsCard → buy/auto/limit) stays explicit
- /topup overview comment: correct the stale 'buy_flow detects no_payment_method'
  note (the overview's no-card gate fires first, so reaching Add funds implies a
  card on file)

Skipped (judgment): the orphaned CreditsView.depleted field (harmless, on a live
dataclass), the defensive card gates in _billing_buy_flow/_confirm_and_charge
(cheap correct defense on the money path), and folding the no-card handoff into a
shared helper (touches 4 money-path sites for tidiness — not worth the risk here).

* fix(billing): reactive charge gating — drop card preflight, react to 403 (scope→reauth, no-card→portal)

* refactor(billing): drop the /credits alias entirely

The /credits fold made it an alias of /topup; now remove that too. Typing
/credits is an unknown command, not a silent redirect — billing lives only on
/topup (with /billing kept as the old command's back-compat name). Dropped the
alias from the registry CommandDef and the TUI topup.ts; updated the test to
assert /credits resolves to nothing (no command, no alias).

* docs(billing): fix stale comment in _billing_overview — describe reactive no-card path

The comment still described the removed overview-level card gate ('no-card case
handled above'). Corrected to: the buy flow reacts to the server's
no_payment_method 403 and hands off to the portal at charge time (no preflight).

* refactor(billing): simplify-pass — share usage-payload helper, drop dead bar wire fields + redundant admin gate

* refactor(billing): drop the /billing alias too — /topup is the only billing command

Following /credits removal, retire the old /billing name as well. /topup now has
NO aliases — both /credits and /billing are unknown commands. Dropped the alias
from the registry CommandDef and TUI topup.ts; fixed the one live user-facing
straggler (the not-logged-in message said 'then /billing' → /topup) and the
_show_billing docstring/default-arg references. Test asserts /topup carries no
aliases and neither old name resolves.

* fix(billing): code-review fixes — money-path + parity bugs

Money path (TUI):
- auto-reload "Turn off" now echoes current threshold/top_up_amount so the
  PATCH succeeds (was sending {enabled:false} → invalid_request → stayed ON)
- charge poll honors the 5-min cap on the 429/503 throttle branch too (was
  rescheduling forever); cap folded into one timedOut() helper
- step-up resume reacts to the replay outcome instead of unconditionally
  closing on a reassuring line with no charge made
- synchronous submit guard on Confirm so two key events can't double-charge

Gateway:
- billing.step_up routes typed errors through _serialize_billing_error (was a
  raw {error:'error'} dict → generic copy for session_revoked)
- billing.state / subscription.state / usage.bars / session.usage moved to
  _LONG_HANDLERS (blocking portal HTTP no longer stalls the main stdin loop)

CLI:
- _billing_render_charge_error handles insufficient_scope without leaking the
  raw billing:manage scope name on a post-grant replay re-raise

Python model:
- subscription_view tier parse None-coalesces tierOrder/dollarsPerMonth so a
  free tier's 0 survives ($0, not "—"; correct sort order)

TUI parity/robustness:
- /usage shows formatted renews_display, not raw ISO renews_at
- subscription overview guards a null pending_downgrade_at (was "on null.")
- subscription overview surfaces a message instead of silently closing when
  portal_url is missing
- buildManageUrl wraps new URL() so a malformed portal_url can't throw out of
  the Ink key handler

* fix(billing): cross-surface bar direction, formatted cancel/downgrade dates, Slack alias gating

- CLI plan bar now fills by REMAINING (fuel-gauge), matching the shared model's
  fill_fraction, the top-up bar, and the TUI — same account renders identically
  on both surfaces (#8)
- subscription serializer emits cancellation_effective_display /
  pending_downgrade_display (format_renews); TUI shows 'Jul 1, 2026' not raw ISO (#14b)
- _SLACK_VIA_HERMES_ONLY now includes the 'billing' alias so it follows its
  canonical /topup via /hermes instead of leaking a native Slack slot (#9)

* fix(billing): thread idempotency key through the TUI step-up replay (#2)

Mint a stable idempotency key when the purchase amount is chosen; it rides
pendingCharge into both the Confirm charge and the post-grant step-up replay,
so a retried charge dedups server-side (the gateway already echoes the key).
A fresh amount selection gets a fresh key. Combined with the sync submit guard,
a double-submit now collapses to one charge.

* refactor(billing): remove dead /subscription tier-picker scaffolding (#18)

The in-terminal plan picker was cut (deep-link only), leaving a whole unreached
state machine. Removed end-to-end:
- TUI: ConfirmScreen, HandoffScreen, the 'confirm'/'handoff' screen types,
  pendingTargetTierId, and the now-dead onPatch threading (collapsed the dispatch
  to a single overview screen + folded the duplicate Box wrapper)
- gateway: the tiers serialization + SubscriptionTierOption wire type
- model: SubscriptionTier, _parse_tier, _coalesce, _dev_tiers and the tiers field
  (never displayed on either surface, so this supersedes the tier-parse fix)
- tests: dropped the confirm/handoff/tier-passthrough tests; slimmed the overview
  render tests

Net: a large dead-code cull (no behavior change — the picker never ran).

* test(billing): parametrize usage-model tests; drop dead is_low/is_free props

Collapse the fail-open + status-classification cases into parametrized tables
(same coverage, ~80 fewer lines) and remove the now-unused UsageModel.is_low /
is_free properties (only a test pinned them).

* fix(billing): revert dead 'billing' Slack-via-hermes entry — the alias was dropped

#9 was based on a stale review diff: /billing is no longer an alias of /topup
(dropped earlier), so routing it via /hermes filtered a name that doesn't exist.

* test(billing): cull redundant TUI billing tests (parametrize, merge dupes)

usageCommand: collapse 3 CTA tests into one + a panel helper.
billingStepUp: merge the two step-up render asserts.
topupCommand: parametrize requestRemoteSpending + the revoked-actor pair, drop
the redundant happy-path-submitted test. Money-path + error-mapping coverage
preserved.

* refactor(billing): extract _usage_bar_lines — one source of truth for the CLI bars

The plan + top-up bar format was copy-pasted across _print_nous_credits_block,
_subscription_overview, and _billing_overview. Extract a helper returning the
ready-to-print lines; each caller keeps its own print fn (the _cprint-ordering
constraint stays) and resolves its plan-name label. Centralizes the format so
the three surfaces can't drift.

* feat(billing): NAS V3 subscription-change HTTP client wrappers

Add the four write-side wrappers for the V3 subscription contract to nous_billing,
each a thin _request() call (reusing auth, JSON, 401-retry, typed errors):
- post_subscription_preview      → POST  /subscription/preview      (chargeless quote)
- put_subscription_pending_change→ PUT   /subscription/pending-change (downgrade/cancel)
- delete_subscription_pending_change → DELETE .../pending-change      (resume/undo)
- post_subscription_upgrade      → POST  /subscription/upgrade        (the money route)

pending-change takes a discriminated body (tier_change | cancellation); upgrade
requires an Idempotency-Key (mandatory, validated client-side before any I/O).
Tests assert the exact method/path/body/header each wrapper puts on the wire.

* feat(billing): subscription tier catalog + change-preview models

Reinstate the catalog the in-terminal picker needs (was culled when /subscription
was deep-link-only): SubscriptionTier + SubscriptionState.tiers + _parse_tier, with
_coalesce so the free tier's 0 tierOrder/price survives a falsy-or. Parse the
catalog from GET /subscription's tiers and seed _dev_tiers into every fixture.

Add SubscriptionChangePreview + subscription_change_preview_from_payload for the
POST /preview quote (effect/amountDueNowCents/effectiveAt/reason + tier delta); a
malformed/missing effect fails safe to 'blocked' so a bad quote never reads as a
charge. Module docstring updated: the overlay is no longer deep-link-only.

* feat(billing): gateway RPCs for the V3 subscription change flow

Add subscription.preview / .change / .resume / .upgrade RPCs, each wrapping its
nous_billing call and reusing _serialize_billing_error for the typed envelope
(so a 403 still drives the device step-up). upgrade mints + echoes the
idempotency key and surfaces status + recovery_url so the TUI can route an
SCA/decline to the portal. Re-add the tier catalog to _serialize_subscription_state
(price pre-formatted) for the picker. All four are pool-routed (_LONG_HANDLERS) —
preview + upgrade hit Stripe and must not stall the main stdin loop.

* feat(billing): in-terminal subscription change flow (TUI)

/subscription is no longer deep-link-only: it drives the change in-terminal
against the V3 contract via the new gateway RPCs. The overlay is a state machine
overview → picker → confirm → result:
- picker lists the tier catalog with upgrade/downgrade hints (current + free
  excluded; free=cancel, on the overview);
- confirm shows the previewed effect — pay $X now (upgrade) / scheduled at date
  (downgrade) / cancel at period end / blocked-with-reason — then applies it;
- an upgrade's SCA/decline routes to the portal via the result screen's recovery
  link; resume/cancel/downgrade are chargeless.

Starting a NEW subscription still deep-links (needs a fresh card). insufficient_scope
points to /topup (the step-up stays there, not duplicated here). Adds the wire
types (tiers + preview/upgrade responses), widens the overlay ctx + screen state,
and threads onPatch. Render tests cover every screen.

* feat(billing): in-terminal step-up + clearer scheduled-change UX (TUI)

Two improvements to the /subscription overlay:

Step-up re-auth in place. When a mutation (preview/change/upgrade/resume) returns
insufficient_scope, route to a new 'stepup' screen that grants terminal billing
via billing.step_up and AUTO-REPLAYS the held action on grant — no bounce to
/topup. Scope routing is centralized in previewAndRoute/applyPendingAndRoute/
resumeAndRoute (shared by the picker, confirm, overview + the step-up replay). The
browser opens via the shared global verification handler; copy never leaks the raw
billing:manage scope.

Make a scheduled change unmissable. A downgrade/cancel was one buried warn line
that read as 'nothing happened'. Now the overview leads with a banner
(⏳ Scheduled change · Ultra ──▶ Plus · <date> · you keep Ultra until then), the
status line echoes the transition (Plan: Ultra → Plus), 'Keep <tier> (undo)' is
promoted to the first olive action, the result screen says 'your plan doesn't
change today', and confirm gets a charged-now / scheduled chip.

* feat(billing): full in-terminal subscription change flow in the classic CLI

Bring the CLI to parity with the TUI overlay — /subscription is no longer
deep-link-only. A paid admin/owner gets picker → preview → confirm → apply,
mirroring the /topup buy flow's modal idioms:
- _subscription_change_menu (change / undo-or-cancel / manage-on-portal),
- _subscription_pick_tier (catalog with upgrade/downgrade hints),
- _subscription_preview_and_confirm (POST /preview → effect-aware confirm),
- _subscription_apply (schedule / cancel / resume chargeless; upgrade charges
  the sub's card, SCA/decline → portal),
- _subscription_handle_scope_required (insufficient_scope → step_up_nous_billing_scope
  inline, then replays the held preview/mutation — reusing the upgrade idempotency key).

Also the scheduled-change UX fix: the overview leads with a prominent banner
(⏳ Scheduled change · Super ──▶ Plus · <date> · you keep Super until then) and the
status line echoes the transition, matching the TUI. Members / non-interactive /
free still deep-link. Tests drive every branch via a mocked modal + nous_billing.

* fix(billing): close TUI subscription money-path holes (ultracode review)

- Un-consented charge (P1): the step-up now HOLDS at a 'granted' phase requiring
  an explicit Continue, and an abortedRef gates the grant's late .then — a cancel
  during the browser flow can no longer replay the held upgrade + charge.
- Missing idempotency key (P2): mint it when building an upgrade 'pending' so it
  rides into confirm AND the step-up replay (was always undefined → gateway minted
  a fresh key per call, defeating dedup).
- Navigate-away re-charge (P2): confirm 'back' is guarded by submittingRef while an
  apply is in flight.
- Ambiguous charge (P2): a transport-null upgrade is reported as 'may or may not
  have charged — re-check', never a flat failure that invites a blind retry.
- Typed step-up denial (P2): requestRemoteSpending returns {granted,error,message};
  the screen maps session_revoked / remote_spending_revoked / rate_limited to the
  right recovery instead of always 'an admin must allow it'.

* fix(billing): close CLI subscription money-path holes (ultracode review)

- Bounded step-up (P2): bust the 30s token cache after a grant (it held the
  pre-grant unscoped token; _request only busts on 401, not 403) and replay ONCE
  with allow_stepup=False so a still-denied scope can't re-prompt/re-open in a loop.
- Stray-keystroke charge (P3→near-P2): the upgrade confirm defaults to 'Go back',
  not 'Pay ' — a bare Enter can't move money.
- Fail-open on unknown effect (P3→near-P2): an unrecognized preview effect now
  fails SAFE (portal hand-off) instead of scheduling a real PUT.
- 'cancel' word collision (P3): the Close row uses value 'close' so typing 'cancel'
  can't hit it and falsely report 'Cancelled'.
- blocked effect re-offers the portal; undo is promoted to the first row when a
  change is pending (TUI parity).

* fix(billing): guard the step-up resume against double-fire (2nd ultracode pass, BUG A)

The P1 fix split the auto-replay into a user-triggered resume() on the granted
screen, where the default row is the charging action — but resume() had no
re-entrancy guard, so a double-Enter fired two replays (the upgrade dedups on the
shared key, but schedule/cancel/resume replays carry none → duplicate PUT/DELETEs).
Mirror billingOverlay.resume(): flip to a 'resuming' phase + a resumingRef so it
fires at most once, and block 'back' once resuming (no re-mount → no second submit).

* fix(billing): CLI charge-route ambiguous-charge caveat (2nd ultracode pass, BUG B)

The TUI hardened upgradeResult(null) but the CLI charging route did not: a
transport/timeout/500 (or unknown 2xx status) on post_subscription_upgrade — after
NAS may have already prorated + charged — printed a flat failure, and a manual
re-run mints a FRESH idempotency key the server can't dedup → a real second charge.
Now the charge route reports 'your card may or may not have been charged — re-run
/subscription to check before trying again' and steers away from a blind retry
(the CLI can't persist the key across a command re-run). Also thread allow_stepup
through the preview→apply replay (BUG C.1) and route the requires_action/
payment_failed portal lines through _cprint for deterministic ordering.

* fix(billing): cap the TUI step-up replay to avoid a resume-deadlock (final pass, R1)

The round-2 resume guard ('resuming' phase + resumingRef) could deadlock: on a
REPEAT insufficient_scope during the post-grant replay, the route helpers did
onPatch({screen:'stepup'}) — a no-op since we're already mounted on stepup (no key
→ no remount) — leaving phase='resuming'/resumingRef=true frozen on 'Applying your
change…'. Thread allowStepUp through previewAndRoute/applyPendingAndRoute/
resumeAndRoute; the resume() replay passes false, so a repeat scope denial surfaces
a 'still isn't enabled' result instead (mirrors the CLI's allow_stepup=False cap).
Also: applyPendingAndRoute(pending=null) now routes to overview, not a stranded
Promise.resolve().

* fix(billing): narrow the CLI ambiguous-charge catch to indeterminate outcomes (final pass, R2)

The round-2 fix caught EVERY non-scope BillingError as 'may or may not have been
charged' — but typed pre-charge rejections (BillingRateLimited 429, BillingSessionRevoked
401, BillingRemoteSpendingRevoked 403, role_required/no_payment_method 4xx) never
reached Stripe, so the ambiguity copy was wrong and dropped their real recovery hints.
Now route those to _subscription_render_error, and reserve the ambiguous copy for
genuinely indeterminate outcomes (network_error / endpoint_unavailable / status None /
5xx). Tests: rate-limit stays deterministic; a real transport failure stays ambiguous.

* feat(billing): card visibility + guided add-card path in /topup and /subscription

Consume the NAS card-resolver contract (card.resolvedVia + chargeability) across
both surfaces, degrading cleanly on today's NAS (fields absent → prior behavior):

- WHICH card: the payment lines render provenance — 'Visa ····4242 — the card on
  your subscription' (resolvedVia → label; unknown rung/older NAS → masked card +
  the old generic line). Link payment methods render the brand alone (last4 is
  empty — never 'Link ····').
- Presence at a glance: the /topup overview now shows 'Card: …' or 'No saved
  card on file' for the full-menu case, plus a warning when the resolver marks
  the card needs_repair (failing auto-reloads) on overview/buy/confirm.
- Add-card path: with no card on file, 'Add funds' becomes a guided screen —
  open the portal billing page, then 'I've added it — check again' re-fetches
  billing state and continues straight into the purchase (also recovers a
  transient display miss). Cards are never entered in-terminal.
- /subscription upgrade confirm names the exact card ('Visa ····4242 — the card
  on your subscription — will be charged'), best-effort via billing.state and
  only when the resolution rung matches what a subscription charge actually
  uses (subPin/customerDefault, mirroring Stripe's precedence); otherwise the
  generic line stands. Fail-soft: any lookup error keeps the generic line.
- Gateway serializes display/resolved_via/needs_repair; TUI ctx gains
  refreshState (topup) + fetchCard (subscription); new offline fixtures
  card-sub / card-repair.

Tests: TUI ctx mocks extended; CLI suites cover provenance + repair-warning
render, the Link guard, the add-card path (continue-after-recheck + abandon),
the sub-confirm card line, and keep the confirm-time lookup offline in tests.

* fix(billing): consume server canChangePlan, preserve distinct refusal codes, drop dead chargeability

- Parse canChangePlan verbatim from NAS payloads into BillingState and
  SubscriptionState; fall back to the legacy OWNER/ADMIN check only when the
  server omits the field (FINANCE_ADMIN stops being locked out where NAS
  authorizes it). Role model updated to the 5-role enum.
- Add the autoReload.card union (canonical | distinct | none) end-to-end:
  parse + gateway serialization, distinct carries payment_method_id/brand/last4
  with nullable display fields.
- stripe_unavailable (503, transient) and upgrade_cap_exceeded (429, daily cap)
  now survive to the wire as their own codes instead of collapsing into
  rate_limited; new exception types subclass BillingRateLimited so existing
  backoff call sites keep working.
- Remove card.chargeability / needs_repair parsing, serialization, fixtures and
  the cli warning blocks: NAS NousResearch#670 removed the field, so the repair path was
  permanently dead. The future card-health signal belongs to the NAS W1/W3 work.
- Tests: five-role fixtures, canChangePlan override/fallback, all three
  auto-reload card variants, 429-vs-503 code preservation end-to-end.

* feat(tui): render the full NAS billing refusal surface

- billingOverlay: divergence notice when auto-refill charges a distinct card
  (portal deep-link to reconcile); needs_repair warnings removed with the field.
- topup: explicit copy for consent_required, org_access_denied,
  upgrade_cap_exceeded, auto_top_up_disabled_failures and stripe_unavailable
  (honors retry_after); processing_error is an explicit charge-failure case;
  transport loss during charge polling now reads as an unconfirmed outcome
  (check balance before retrying), matching the revocation path.
- subscriptionOverlay: branch on upgrade reason, not status, so an SCA-needing
  upgrade routes to portal verification even while NAS pre-NousResearch#711 labels it
  payment_failed; after an upgrade, poll subscription state until the tier
  flips (bounded), rendering applying/still-applying rather than assuming
  immediacy.
- Capability-neutral refusal copy (owner, admin, or finance admin) replaces
  the stale org admin/owner wording.
- gatewayTypes: BillingAutoReload.card union added, needs_repair removed.

* docs(billing): client-side billing state and refusal lifecycle table

Enumerates, from the code, every billing.state shape and typed refusal the
gateway serves and the exact TUI copy + recovery each renders. Acceptance from
the billing-integration handoff: no NAS billing state or typed refusal falls
through to a generic toast; unknown codes still degrade to the default branch
that surfaces the server message.
alt-glitch added a commit that referenced this pull request Jul 21, 2026
* feat(tui): rename /billing slash command to /topup

Behavior-preserving rename of the /billing command surface to /topup.
Changes: billing.ts → topup.ts (export topupCommands, name 'topup', new
help string), registry.ts import+spread updated, billingOverlay.tsx
overview header 'Usage credits' → 'Top up credits', billingCommand.test.ts
→ topupCommand.test.ts with import/lookup/call updated. RPC method names
(billing.state, billing.charge, etc.) and component/symbol names unchanged.

* refactor(tui): extract overlay primitives to shared module

Lift MenuRow, ActionRow, footer, and barCells() out of billingOverlay.tsx
into overlayPrimitives.tsx so the upcoming subscriptionOverlay.tsx can
import them instead of duplicating. spendBar now calls barCells() —
output is byte-identical. Pure behavior-preserving refactor.

* feat(tui): add /subscription + /topup CTAs to /usage output

Every /usage render now ends with 'Run /subscription to change plan
· /topup to add credits' — both the healthy (with-calls) and depleted
(no-calls) paths. Strings-only change, no WS1 dependency.

* feat(tui): add subscription wire types

Add SubscriptionTierOption, SubscriptionStateResponse, and
SubscriptionManageLinkResponse to gatewayTypes.ts. Type-only — no
usages yet. Mirrors the BillingStateResponse conventions (snake_case,
Decimals as strings) and reuses BillingErrorPayload for error mapping.

* feat(gateway): add subscription.state + subscription.manage_link RPCs

- agent/subscription_view.py: SubscriptionState dataclass + fail-open
  build_subscription_state() (mirrors billing_view pattern) +
  get_subscription_manage_link() for the Stripe deep-link.
- hermes_cli/nous_billing.py: get_subscription_state() +
  post_subscription_manage_link() HTTP helpers for the two NAS endpoints
  (WS1 Phase A/C). The manage-link endpoint raises BillingScopeRequired
  when Remote-Spending is missing (Phase 4 step-up trigger).
- tui_gateway/server.py: _serialize_subscription_state() +
  subscription.state RPC (fail-open) + subscription.manage_link RPC
  (returns {ok,kind,url} or typed error envelope via
  _serialize_billing_error). NOT added to _LONG_HANDLERS — synchronous
  HTTP round-trip, not a device flow.

* feat(tui): add subscription overlay state types + store slot

Add SubscriptionScreen, SubscriptionOverlayCtx, SubscriptionOverlayState
to interfaces.ts and a 'subscription' slot to OverlayState. Wire it into
overlayStore.ts (buildOverlayState + $isBlocked). NOT added to
resetFlowOverlays preserve list — flow-scoped like billing, drops on
turn end.

* feat(tui): build SubscriptionOverlay — overview + confirm + handoff

Pure-render Ink component mirroring billingOverlay.tsx's structure.
Overview screen covers all 5 states (free-upgradeable, mid-tier,
top-tier, not-admin, downgrade-pending) + dunning. Confirm screen is
y/n deep-link to Stripe (NO in-terminal charge). Handoff is the
transient 'Opening Stripe' screen. Imports shared primitives from
overlayPrimitives.tsx. 8 render tests via renderSync covering every
state.

* feat(tui): add /subscription command + overlay wiring

- subscription.ts: SubscriptionOverlayCtx closure (openManageLink,
  refreshState, requestRemoteSpending) + run handler that fetches
  subscription.state and opens the overlay. Alias /upgrade.
- registry.ts: spread subscriptionCommands into SLASH_COMMANDS.
- appOverlays.tsx: render SubscriptionOverlay when overlay.subscription set.
- useInputHandlers.ts: Esc closes subscription overlay; promptOverlay OR
  includes subscription so input is intercepted while open.
- subscriptionCommand.test.ts: 4 tests (fetch+open, logged-out sys line,
  /upgrade alias, /subscription resolves).

* fix(tui/subscription): stop saying Stripe in deep-link copy + fix manage link kind type

Replace all user-facing 'Stripe' mentions in the /subscription overlay and
sys messages with 'your subscription page' — the deep-link target is NAS's
own /manage-subscription page, not the Stripe hosted portal. Stripe only
legitimately appears later at actual Checkout. Also add 'manage' to the
SubscriptionManageLinkResponse.kind union (NAS emits kind:'manage'; was
previously missing from the TypeScript type causing silent narrowing errors).

* feat(tui/subscription): render cancellation-scheduled note with headline precedence

Parse cancelAtPeriodEnd + cancellationEffectiveAt from the NAS contract
(camelCase) in the agent parser (_parse_current), emit cancel_at_period_end
+ cancellation_effective_at from the gateway serializer, extend the
SubscriptionStateResponse type, and render a warn note in OverviewScreen:
'Cancels on {date} — your plan stays active until then.'

Headline precedence when multiple flags co-occur:
  past-due > cancel-scheduled > downgrade-pending > active
The downgradeNote guard is tightened to suppress when cancel is scheduled,
so at most one status line renders at a time.

* feat(tui/subscription): team-context screen — redirect to /topup for team orgs

Parse the NAS context:'personal'|'team' field (defaults to 'personal' for
unknown/missing values), emit it on the gateway wire, add it to
SubscriptionStateResponse. When context is 'team', SubscriptionOverlay
renders a dedicated read-only screen instead of the tier picker:

  'This terminal is connected to {org_name}. Teams run on shared
   credits — use /topup to add funds. Personal subscriptions live
   on your personal account.'

The screen closes on Enter or Esc. The personal/tier-picker path is
unchanged.

* fix(subscription): drop manage-link gateway RPC, build URL locally

The NAS POST /api/billing/subscription/manage-link endpoint was dropped
(it added no server work — the target is the static /manage-subscription
page, not a Stripe-minted secret). Build the URL client-side instead:
{portal_base}/manage-subscription?org_id=<org.id>.

- Remove subscription.manage_link gateway RPC (server.py)
- Remove get_subscription_manage_link helper (subscription_view.py)
- Remove post_subscription_manage_link (nous_billing.py)
- Remove SubscriptionManageLinkResponse type (gatewayTypes.ts)
- Add org_id to SubscriptionState + wire through serializer + TS type
- openManageLink() builds the URL locally via buildManageUrl(), opens
  it with the existing openExternalUrl(), no gateway round-trip
- Drop targetTierId param from openManageLink (v1 sends everyone to
  /manage-subscription; no tier deep-link needed)
- Fix stale test expectations (Stripe copy → subscription page copy)

* chore(subscription): drop unused format_money import

* feat(cli): /subscription + /upgrade, /billing→/topup rename, /usage CTAs

Add the classic-CLI half of the terminal billing surface to match the TUI:
- /subscription (alias /upgrade) command + /topup (renamed /billing, keeps
  'billing' as a back-compat alias) in the command registry.
- Drop the stale 'billing' entry from _SLACK_VIA_HERMES_ONLY (now cli_only).

* feat(subscription): CLI /subscription handler, drop dunning, current:null no-plan

- CLI _show_subscription mirrors the TUI overlay (plan read + tier list + usage
  bar + browser deep-link via subscription_manage_url); credits render as counts.
- Adapt to the updated NAS read contract: remove is_past_due/dunning everywhere
  (a card-failing subscriber returns as a normal plan now), and treat no-plan as
  current:null (parser returns None) rather than an all-null object.
- HERMES_DEV_SUBSCRIPTION_FIXTURE env-driven fixtures + ui-tui fixture harness
  drive every state (CLI + live TUI) with no portal.

Verified against handoff 2026-06-24_subscription-tui-handoff.md.

* feat(billing): CF-4 Remote-Spending revoked-terminal UX (NAS PR #481)

Wire the Remote-Spending gate denial contract end to end:
- nous_billing: BillingRemoteSpendingRevoked (403 remote_spending_revoked →
  reconnect) + BillingSessionRevoked (401 session_revoked → re-login), distinct
  from insufficient_scope; capture actor/code/recovery; 503 stays transient.
- gateway _serialize_billing_error threads the new typed kinds + actor/code/
  recovery to the TUI.
- TUI renderBillingError: actor-aware revoke copy, kills the spend overlay
  immediately (no 15-min zombie button), handles session_revoked, the dual-
  emitted cli_billing_disabled/remote_spending_disabled, role_required,
  idempotency_conflict; poll treats a mid-poll revoke as ambiguous (check
  balance before retry), not a failure.
- CLI _billing_render_charge_error: same denial matrix, actor-aware copy.

Tests: gate-contract mapping + envelope (py) and revoke/session/disabled (TUI).
Per handoff 2026-06-24_remote-spending-TUI-contract-handoff.md.

* refactor(subscription): remove dead step-up scaffolding from /subscription

/subscription only opens a browser deep-link to manage-subscription — that needs
no billing scope, so it can never hit insufficient_scope. Drop the never-fired
'stepup' screen type, requestRemoteSpending ctx fn, and resumeScreen bookkeeping
(leftovers from a superseded plan). The resumable step-up lives on /topup, where
the charge actually gets gated.

* feat(tui/topup): resumable 'Allow Remote Spending' step-up on the charge path

Phase 4: when a charge returns insufficient_scope, the /topup modal no longer
tears down with a 'run /billing again' ConfirmReq. Instead it stays MOUNTED and
switches to a step-up screen:
- charge() is now awaitable, returning a discriminated outcome (submitted |
  needs_remote_spending | error) so the overlay can route without closing.
- StepUpScreen: 'Allow Remote Spending' → await the device-flow grant (browser
  opens via the existing out-of-band billing.step_up.verification event) →
  replay the held charge (pendingCharge.amount) and settle, with no command
  re-run. Never surfaces the raw billing:manage scope.
- armStepUp's fire-and-forget ConfirmReq replaced by requestRemoteSpending();
  the leaky 'billing:manage' / 'Re-authorize' / 'run /billing again' copy is gone.

Tests: charge-outcome routing, step-up grant/deny, and a render test asserting
the step-up copy holds the amount and never leaks billing:manage.
Per handoff 2026-06-24_remote-spending-TUI-contract-handoff.md §2 (Grady #6).

* feat(billing): shared dollar usage model + two-bar view (drop "credits")

Single source of truth for the /usage and /subscription usage bars across
TUI + CLI. Reads the NAS account-info dollar fields (subscription/top-up/total
remaining, monthly allowance, renewal) and produces a surface-agnostic model:
two full-resolution bars (plan allowance + purchased top-up), a status
classification (free | healthy | low | depleted), and a human renewal date.

- agent/billing_usage.py: UsageModel/UsageBar, usage_model_from_account
  (fail-open), build_usage_model (HERMES_DEV_CREDITS_FIXTURE-aware),
  format_renews (ISO -> "Jul 24, 2026", Windows-safe), $5 low-balance threshold.
- tui_gateway/server.py: _serialize_usage_model/_serialize_usage_bar, a
  usage.bars RPC, and the model embedded into subscription.state so the overlay
  renders the same bars from its single fetch.
- Dollars only, never "credits"; two separate bars (not a crammed
  three-segment one) for legibility at terminal widths.
- tests/agent/test_billing_usage.py: status classification, bar math
  (clamp/over-cap), NaN/Inf rejection, fail-open invariants.

* feat(tui): dollar usage bars on /usage + /subscription, drop tier picker

Render the shared two-bar dollar model in both overlays; strip "credits" and
the in-terminal tier selection per UX feedback.

- overlayPrimitives.tsx: UsageBars (themed plan/top-up bars — gold allowance,
  green top-up) + usageBarsText for the /usage panel. Plan name labels the
  bar; "$X left of $Y · N% used" (disambiguated so the % matches); top-up
  "never expires".
- subscriptionOverlay.tsx: status line dedupes ($X left once; bar carries the
  breakdown), human renewal date, state-matched nudges (free upsell / <$5
  low alert) with box-safe ASCII markers (! / >) instead of the width-unstable
  emoji that broke the border. Tier picker removed — overview shows usage +
  plan, then "Manage on portal" / "Close" (free users get "Start a
  subscription"). No "credits" anywhere.
- session.ts: /usage renders the dollar bars + balance summary, falling back
  to the legacy credits lines only when the model is unavailable; CTA reworded.
- gatewayTypes.ts: UsageModelData/UsageBarData wire types + usage on
  SessionUsageResponse/SubscriptionStateResponse.
- Tests updated to the new contract (no "credits", "left of", dedup, markers).

* feat(cli): mirror dollar usage bars on /usage + /subscription

CLI parity with the TUI billing rework, from the same shared usage model.

- _print_nous_credits_block (/usage) and _subscription_overview render the
  two-bar dollar view (plan name on the bar, "$X left of $Y · N% used",
  top-up "never expires", total spendable) instead of the credits-worded block.
- Dollars only — dropped the tier catalog (no more "$N/mo (… credits)") and
  every user-facing "credits"; team copy says "shared balance".
- Human renewal date via the shared format_renews; status line dedupes the
  "$X left"; free upsell + <$5 low alert with ASCII markers.
- /subscription manage modal no longer dumps the raw manage-subscription URL
  in its detail — the [1] Open / [2] Copy link / [3] Cancel options carry it.
  Title is "Manage your subscription" (no in-terminal plan change). The raw URL
  stays only in the non-interactive / not-admin fallbacks, which have no menu.
- /usage token-usage panel (model, tokens, cost, context) left untouched.

* feat(billing): embed dollar usage model into billing.state for /topup

The /topup overview renders the same two-bar dollar usage (plan + top-up) as
/usage and /subscription. Embed the shared usage model into the billing.state
RPC payload (mirrors subscription.state) so the overlay gets the bars from its
single fetch, and add the `usage` field to BillingStateResponse.

* feat(tui/topup): reorder overview + in-flight reauth with press-Enter resume

Reworks the /topup overlay per the Jun 19 review and the no-preflight decision.

Overview:
- Balance leads in the title ("Top up · balance $X"); the shared two-bar dollar
  usage (plan + top-up) renders below. Dropped the old monthly-cap spend bar.
- "Add funds" is the first action (was "Buy credits"); auto-reload / monthly
  limit / manage-on-portal follow. Dollars only — no "credits" anywhere.
- No "Enable terminal billing" menu item and NO scope preflight: whether the
  terminal can charge is discovered reactively at pay time. (We deliberately do
  not read/refresh the OAuth token to gate UI.)

Step-up (reached only on a charge's insufficient_scope 403):
- New 4-phase flow that keeps the modal mounted: prompt (one-time-setup
  heads-up) → waiting (browser authorize) → granted (explicit "Press Enter to
  resume") → replay the held charge → settle. The press-Enter beat is the
  reassuring "you're back, finish your purchase" moment.
- Renamed user copy "Allow Remote Spending" → "Enable terminal billing"; never
  leaks the raw billing:manage scope (guarded by the render test).
- topup.ts error copy de-crufted to terminal-billing wording, emoji removed.

Tests: step-up prompt copy, the no-raw-scope invariant, and new overview tests
(balance-in-title, Add-funds-first, two-bar usage, no "credits").

* feat(cli/topup): mirror overview reorder + in-flight reauth resume

CLI parity with the TUI /topup rehaul, from the same shared usage model.

- _billing_overview: balance in the title, the two-bar dollar usage (plan name
  on the plan bar, top-up "never expires") in place of the old cap spend bar,
  "Add funds" first, dollars throughout — no "credits", no scope preflight.
- _billing_handle_scope_required: now takes the held amount + idempotency key
  and runs the in-flight flow — "Enable terminal billing" → browser device-flow
  → re-check the org kill-switch → press-Enter to resume → replay the held
  charge (reusing the key so a double-submit collapses to one). Stops leaking
  the raw billing:manage scope.
- Charge-error + buy/auto-reload copy de-crufted to terminal-billing/dollars.
- Tests updated to the new overview + buy copy.

* fix(billing): guard non-JSON 2xx responses in the billing HTTP client

A 2xx response with a non-JSON body — e.g. a reverse-proxy / SPA fallback HTML
page served when a billing route isn't actually mounted on a deployment — hit
json.loads() on the success path of _request() and raised a raw
json.JSONDecodeError. That escaped the typed-BillingError contract, so callers'
`except BillingError` missed it and fell through to a generic fail-open that
rendered as a misleading "not logged in" (observed when /api/billing/subscription
was briefly unshipped on staging: 200 text/html, x-matched-path /[...notFound]).

Now a non-JSON 2xx body raises a typed BillingError(error="endpoint_unavailable")
so surfaces degrade gracefully ("could not load …") instead of crashing or
mislabeling a valid session as logged-out. The 4xx/5xx path already guarded its
.json(); this closes the same hole on the success path.

Test: tests/hermes_cli/test_nous_billing_request.py — non-JSON 2xx → typed
error (not JSONDecodeError, not BillingAuthError), empty body → {}, valid JSON
parses.

* feat(billing/dev): add HERMES_DEV_BILLING_FIXTURE for offline card/scope testing

build_billing_state short-circuits to a fixture when HERMES_DEV_BILLING_FIXTURE
is set (mirrors HERMES_DEV_CREDITS_FIXTURE for the usage model). States:
nocard | card | card-autoreload | notadmin | billing-off | logged-out — so the
card-on-file gate, admin role, and kill-switch paths are exercisable offline
without a live portal. Env-var gated; returns None when unset (no prod leak).

Adds 8 behavior tests asserting the card/admin/billing-on contract per state.

* refactor(billing): fold /credits into /topup

/credits is redundant now that /topup shows the dollar balance + portal handoff.
Make 'credits' (and 'billing') aliases of /topup so typing /credits still works,
resolving to topup everywhere (CLI, gateway, Slack, TUI, autocomplete, help).

Remove the standalone /credits surface across 6 places:
- CLI _show_credits handler + dispatch
- gateway _handle_credits_command -> renamed _handle_topup_command, copy softened
  to 'Manage billing on the portal' (the messaging billing surface; /topup is now
  gateway-available so messaging keeps billing — credits was the only one before)
- TUI commands/credits.ts + creditsCommand.test.ts (deleted), registry entry
- tui_gateway credits.view RPC + the CreditsViewResponse type
- Slack _SLACK_VIA_HERMES_ONLY: credits -> topup

Sweep user-facing /credits -> /topup (usage-block hint, depletion notice) and
stale doc-comments. OpenRouter's /credits endpoint URL left untouched. Tests
updated (test_credits_folds_into_topup) or pruned for the removed symbols.

* fix(billing): card-on-file heads-up, no-card portal gate, /usage bar ordering, modal glyph

In-terminal charge (POST /charge against the org's server-held card, no card ref
leaves the client):
- card present: confirm screen shows 'Your card saved on the portal will be
  charged' + a 'Manage on portal' escape option (CLI); heads-up line (TUI)
- no card on file: /topup overview + buy flow detect it and route to the portal
  to add a card, instead of offering a charge that 403s no_payment_method

/usage bar ordering: route the dollar block through _cprint consistently. The
Plan: line (_cprint) and the bar (raw print) flushed to different buffers under
patch_stdout and interleaved nondeterministically; now Plan: -> bar -> status/CTA
is stable across all states.

Modal glyph: strip the leading emoji from bordered _prompt_text_input_modal
titles — it measures 1 char but renders 2 columns, shifting the box's right
border (the stray '|'). Includes the f-string 'Pay $X?' title.

Small /credits -> /topup string bits in cli.py ride along with the surrounding
charge edits (the fold lives in the sibling refactor commit).

* refactor(billing): apply safe simplify-pass fixes

Three low-risk cleanups from a parallel simplify review (reuse/quality/efficiency):
- dev fixture portal URL: reuse the prod host (was drifted to staging-* — a real
  mismatch vs subscription_view's _DEV_FIXTURE_PORTAL)
- TUI billingOverlay choose(): collapse two byte-identical branches (needsCard +
  the not-full else both = portal-or-close at index 0) into one tail; the only
  divergent path (full && !needsCard → buy/auto/limit) stays explicit
- /topup overview comment: correct the stale 'buy_flow detects no_payment_method'
  note (the overview's no-card gate fires first, so reaching Add funds implies a
  card on file)

Skipped (judgment): the orphaned CreditsView.depleted field (harmless, on a live
dataclass), the defensive card gates in _billing_buy_flow/_confirm_and_charge
(cheap correct defense on the money path), and folding the no-card handoff into a
shared helper (touches 4 money-path sites for tidiness — not worth the risk here).

* fix(billing): reactive charge gating — drop card preflight, react to 403 (scope→reauth, no-card→portal)

* refactor(billing): drop the /credits alias entirely

The /credits fold made it an alias of /topup; now remove that too. Typing
/credits is an unknown command, not a silent redirect — billing lives only on
/topup (with /billing kept as the old command's back-compat name). Dropped the
alias from the registry CommandDef and the TUI topup.ts; updated the test to
assert /credits resolves to nothing (no command, no alias).

* docs(billing): fix stale comment in _billing_overview — describe reactive no-card path

The comment still described the removed overview-level card gate ('no-card case
handled above'). Corrected to: the buy flow reacts to the server's
no_payment_method 403 and hands off to the portal at charge time (no preflight).

* refactor(billing): simplify-pass — share usage-payload helper, drop dead bar wire fields + redundant admin gate

* refactor(billing): drop the /billing alias too — /topup is the only billing command

Following /credits removal, retire the old /billing name as well. /topup now has
NO aliases — both /credits and /billing are unknown commands. Dropped the alias
from the registry CommandDef and TUI topup.ts; fixed the one live user-facing
straggler (the not-logged-in message said 'then /billing' → /topup) and the
_show_billing docstring/default-arg references. Test asserts /topup carries no
aliases and neither old name resolves.

* fix(billing): code-review fixes — money-path + parity bugs

Money path (TUI):
- auto-reload "Turn off" now echoes current threshold/top_up_amount so the
  PATCH succeeds (was sending {enabled:false} → invalid_request → stayed ON)
- charge poll honors the 5-min cap on the 429/503 throttle branch too (was
  rescheduling forever); cap folded into one timedOut() helper
- step-up resume reacts to the replay outcome instead of unconditionally
  closing on a reassuring line with no charge made
- synchronous submit guard on Confirm so two key events can't double-charge

Gateway:
- billing.step_up routes typed errors through _serialize_billing_error (was a
  raw {error:'error'} dict → generic copy for session_revoked)
- billing.state / subscription.state / usage.bars / session.usage moved to
  _LONG_HANDLERS (blocking portal HTTP no longer stalls the main stdin loop)

CLI:
- _billing_render_charge_error handles insufficient_scope without leaking the
  raw billing:manage scope name on a post-grant replay re-raise

Python model:
- subscription_view tier parse None-coalesces tierOrder/dollarsPerMonth so a
  free tier's 0 survives ($0, not "—"; correct sort order)

TUI parity/robustness:
- /usage shows formatted renews_display, not raw ISO renews_at
- subscription overview guards a null pending_downgrade_at (was "on null.")
- subscription overview surfaces a message instead of silently closing when
  portal_url is missing
- buildManageUrl wraps new URL() so a malformed portal_url can't throw out of
  the Ink key handler

* fix(billing): cross-surface bar direction, formatted cancel/downgrade dates, Slack alias gating

- CLI plan bar now fills by REMAINING (fuel-gauge), matching the shared model's
  fill_fraction, the top-up bar, and the TUI — same account renders identically
  on both surfaces (#8)
- subscription serializer emits cancellation_effective_display /
  pending_downgrade_display (format_renews); TUI shows 'Jul 1, 2026' not raw ISO (#14b)
- _SLACK_VIA_HERMES_ONLY now includes the 'billing' alias so it follows its
  canonical /topup via /hermes instead of leaking a native Slack slot (#9)

* fix(billing): thread idempotency key through the TUI step-up replay (#2)

Mint a stable idempotency key when the purchase amount is chosen; it rides
pendingCharge into both the Confirm charge and the post-grant step-up replay,
so a retried charge dedups server-side (the gateway already echoes the key).
A fresh amount selection gets a fresh key. Combined with the sync submit guard,
a double-submit now collapses to one charge.

* refactor(billing): remove dead /subscription tier-picker scaffolding (#18)

The in-terminal plan picker was cut (deep-link only), leaving a whole unreached
state machine. Removed end-to-end:
- TUI: ConfirmScreen, HandoffScreen, the 'confirm'/'handoff' screen types,
  pendingTargetTierId, and the now-dead onPatch threading (collapsed the dispatch
  to a single overview screen + folded the duplicate Box wrapper)
- gateway: the tiers serialization + SubscriptionTierOption wire type
- model: SubscriptionTier, _parse_tier, _coalesce, _dev_tiers and the tiers field
  (never displayed on either surface, so this supersedes the tier-parse fix)
- tests: dropped the confirm/handoff/tier-passthrough tests; slimmed the overview
  render tests

Net: a large dead-code cull (no behavior change — the picker never ran).

* test(billing): parametrize usage-model tests; drop dead is_low/is_free props

Collapse the fail-open + status-classification cases into parametrized tables
(same coverage, ~80 fewer lines) and remove the now-unused UsageModel.is_low /
is_free properties (only a test pinned them).

* fix(billing): revert dead 'billing' Slack-via-hermes entry — the alias was dropped

#9 was based on a stale review diff: /billing is no longer an alias of /topup
(dropped earlier), so routing it via /hermes filtered a name that doesn't exist.

* test(billing): cull redundant TUI billing tests (parametrize, merge dupes)

usageCommand: collapse 3 CTA tests into one + a panel helper.
billingStepUp: merge the two step-up render asserts.
topupCommand: parametrize requestRemoteSpending + the revoked-actor pair, drop
the redundant happy-path-submitted test. Money-path + error-mapping coverage
preserved.

* refactor(billing): extract _usage_bar_lines — one source of truth for the CLI bars

The plan + top-up bar format was copy-pasted across _print_nous_credits_block,
_subscription_overview, and _billing_overview. Extract a helper returning the
ready-to-print lines; each caller keeps its own print fn (the _cprint-ordering
constraint stays) and resolves its plan-name label. Centralizes the format so
the three surfaces can't drift.

* feat(billing): NAS V3 subscription-change HTTP client wrappers

Add the four write-side wrappers for the V3 subscription contract to nous_billing,
each a thin _request() call (reusing auth, JSON, 401-retry, typed errors):
- post_subscription_preview      → POST  /subscription/preview      (chargeless quote)
- put_subscription_pending_change→ PUT   /subscription/pending-change (downgrade/cancel)
- delete_subscription_pending_change → DELETE .../pending-change      (resume/undo)
- post_subscription_upgrade      → POST  /subscription/upgrade        (the money route)

pending-change takes a discriminated body (tier_change | cancellation); upgrade
requires an Idempotency-Key (mandatory, validated client-side before any I/O).
Tests assert the exact method/path/body/header each wrapper puts on the wire.

* feat(billing): subscription tier catalog + change-preview models

Reinstate the catalog the in-terminal picker needs (was culled when /subscription
was deep-link-only): SubscriptionTier + SubscriptionState.tiers + _parse_tier, with
_coalesce so the free tier's 0 tierOrder/price survives a falsy-or. Parse the
catalog from GET /subscription's tiers and seed _dev_tiers into every fixture.

Add SubscriptionChangePreview + subscription_change_preview_from_payload for the
POST /preview quote (effect/amountDueNowCents/effectiveAt/reason + tier delta); a
malformed/missing effect fails safe to 'blocked' so a bad quote never reads as a
charge. Module docstring updated: the overlay is no longer deep-link-only.

* feat(billing): gateway RPCs for the V3 subscription change flow

Add subscription.preview / .change / .resume / .upgrade RPCs, each wrapping its
nous_billing call and reusing _serialize_billing_error for the typed envelope
(so a 403 still drives the device step-up). upgrade mints + echoes the
idempotency key and surfaces status + recovery_url so the TUI can route an
SCA/decline to the portal. Re-add the tier catalog to _serialize_subscription_state
(price pre-formatted) for the picker. All four are pool-routed (_LONG_HANDLERS) —
preview + upgrade hit Stripe and must not stall the main stdin loop.

* feat(billing): in-terminal subscription change flow (TUI)

/subscription is no longer deep-link-only: it drives the change in-terminal
against the V3 contract via the new gateway RPCs. The overlay is a state machine
overview → picker → confirm → result:
- picker lists the tier catalog with upgrade/downgrade hints (current + free
  excluded; free=cancel, on the overview);
- confirm shows the previewed effect — pay $X now (upgrade) / scheduled at date
  (downgrade) / cancel at period end / blocked-with-reason — then applies it;
- an upgrade's SCA/decline routes to the portal via the result screen's recovery
  link; resume/cancel/downgrade are chargeless.

Starting a NEW subscription still deep-links (needs a fresh card). insufficient_scope
points to /topup (the step-up stays there, not duplicated here). Adds the wire
types (tiers + preview/upgrade responses), widens the overlay ctx + screen state,
and threads onPatch. Render tests cover every screen.

* feat(billing): in-terminal step-up + clearer scheduled-change UX (TUI)

Two improvements to the /subscription overlay:

Step-up re-auth in place. When a mutation (preview/change/upgrade/resume) returns
insufficient_scope, route to a new 'stepup' screen that grants terminal billing
via billing.step_up and AUTO-REPLAYS the held action on grant — no bounce to
/topup. Scope routing is centralized in previewAndRoute/applyPendingAndRoute/
resumeAndRoute (shared by the picker, confirm, overview + the step-up replay). The
browser opens via the shared global verification handler; copy never leaks the raw
billing:manage scope.

Make a scheduled change unmissable. A downgrade/cancel was one buried warn line
that read as 'nothing happened'. Now the overview leads with a banner
(⏳ Scheduled change · Ultra ──▶ Plus · <date> · you keep Ultra until then), the
status line echoes the transition (Plan: Ultra → Plus), 'Keep <tier> (undo)' is
promoted to the first olive action, the result screen says 'your plan doesn't
change today', and confirm gets a charged-now / scheduled chip.

* feat(billing): full in-terminal subscription change flow in the classic CLI

Bring the CLI to parity with the TUI overlay — /subscription is no longer
deep-link-only. A paid admin/owner gets picker → preview → confirm → apply,
mirroring the /topup buy flow's modal idioms:
- _subscription_change_menu (change / undo-or-cancel / manage-on-portal),
- _subscription_pick_tier (catalog with upgrade/downgrade hints),
- _subscription_preview_and_confirm (POST /preview → effect-aware confirm),
- _subscription_apply (schedule / cancel / resume chargeless; upgrade charges
  the sub's card, SCA/decline → portal),
- _subscription_handle_scope_required (insufficient_scope → step_up_nous_billing_scope
  inline, then replays the held preview/mutation — reusing the upgrade idempotency key).

Also the scheduled-change UX fix: the overview leads with a prominent banner
(⏳ Scheduled change · Super ──▶ Plus · <date> · you keep Super until then) and the
status line echoes the transition, matching the TUI. Members / non-interactive /
free still deep-link. Tests drive every branch via a mocked modal + nous_billing.

* fix(billing): close TUI subscription money-path holes (ultracode review)

- Un-consented charge (P1): the step-up now HOLDS at a 'granted' phase requiring
  an explicit Continue, and an abortedRef gates the grant's late .then — a cancel
  during the browser flow can no longer replay the held upgrade + charge.
- Missing idempotency key (P2): mint it when building an upgrade 'pending' so it
  rides into confirm AND the step-up replay (was always undefined → gateway minted
  a fresh key per call, defeating dedup).
- Navigate-away re-charge (P2): confirm 'back' is guarded by submittingRef while an
  apply is in flight.
- Ambiguous charge (P2): a transport-null upgrade is reported as 'may or may not
  have charged — re-check', never a flat failure that invites a blind retry.
- Typed step-up denial (P2): requestRemoteSpending returns {granted,error,message};
  the screen maps session_revoked / remote_spending_revoked / rate_limited to the
  right recovery instead of always 'an admin must allow it'.

* fix(billing): close CLI subscription money-path holes (ultracode review)

- Bounded step-up (P2): bust the 30s token cache after a grant (it held the
  pre-grant unscoped token; _request only busts on 401, not 403) and replay ONCE
  with allow_stepup=False so a still-denied scope can't re-prompt/re-open in a loop.
- Stray-keystroke charge (P3→near-P2): the upgrade confirm defaults to 'Go back',
  not 'Pay ' — a bare Enter can't move money.
- Fail-open on unknown effect (P3→near-P2): an unrecognized preview effect now
  fails SAFE (portal hand-off) instead of scheduling a real PUT.
- 'cancel' word collision (P3): the Close row uses value 'close' so typing 'cancel'
  can't hit it and falsely report 'Cancelled'.
- blocked effect re-offers the portal; undo is promoted to the first row when a
  change is pending (TUI parity).

* fix(billing): guard the step-up resume against double-fire (2nd ultracode pass, BUG A)

The P1 fix split the auto-replay into a user-triggered resume() on the granted
screen, where the default row is the charging action — but resume() had no
re-entrancy guard, so a double-Enter fired two replays (the upgrade dedups on the
shared key, but schedule/cancel/resume replays carry none → duplicate PUT/DELETEs).
Mirror billingOverlay.resume(): flip to a 'resuming' phase + a resumingRef so it
fires at most once, and block 'back' once resuming (no re-mount → no second submit).

* fix(billing): CLI charge-route ambiguous-charge caveat (2nd ultracode pass, BUG B)

The TUI hardened upgradeResult(null) but the CLI charging route did not: a
transport/timeout/500 (or unknown 2xx status) on post_subscription_upgrade — after
NAS may have already prorated + charged — printed a flat failure, and a manual
re-run mints a FRESH idempotency key the server can't dedup → a real second charge.
Now the charge route reports 'your card may or may not have been charged — re-run
/subscription to check before trying again' and steers away from a blind retry
(the CLI can't persist the key across a command re-run). Also thread allow_stepup
through the preview→apply replay (BUG C.1) and route the requires_action/
payment_failed portal lines through _cprint for deterministic ordering.

* fix(billing): cap the TUI step-up replay to avoid a resume-deadlock (final pass, R1)

The round-2 resume guard ('resuming' phase + resumingRef) could deadlock: on a
REPEAT insufficient_scope during the post-grant replay, the route helpers did
onPatch({screen:'stepup'}) — a no-op since we're already mounted on stepup (no key
→ no remount) — leaving phase='resuming'/resumingRef=true frozen on 'Applying your
change…'. Thread allowStepUp through previewAndRoute/applyPendingAndRoute/
resumeAndRoute; the resume() replay passes false, so a repeat scope denial surfaces
a 'still isn't enabled' result instead (mirrors the CLI's allow_stepup=False cap).
Also: applyPendingAndRoute(pending=null) now routes to overview, not a stranded
Promise.resolve().

* fix(billing): narrow the CLI ambiguous-charge catch to indeterminate outcomes (final pass, R2)

The round-2 fix caught EVERY non-scope BillingError as 'may or may not have been
charged' — but typed pre-charge rejections (BillingRateLimited 429, BillingSessionRevoked
401, BillingRemoteSpendingRevoked 403, role_required/no_payment_method 4xx) never
reached Stripe, so the ambiguity copy was wrong and dropped their real recovery hints.
Now route those to _subscription_render_error, and reserve the ambiguous copy for
genuinely indeterminate outcomes (network_error / endpoint_unavailable / status None /
5xx). Tests: rate-limit stays deterministic; a real transport failure stays ambiguous.

* feat(billing): card visibility + guided add-card path in /topup and /subscription

Consume the NAS card-resolver contract (card.resolvedVia + chargeability) across
both surfaces, degrading cleanly on today's NAS (fields absent → prior behavior):

- WHICH card: the payment lines render provenance — 'Visa ····4242 — the card on
  your subscription' (resolvedVia → label; unknown rung/older NAS → masked card +
  the old generic line). Link payment methods render the brand alone (last4 is
  empty — never 'Link ····').
- Presence at a glance: the /topup overview now shows 'Card: …' or 'No saved
  card on file' for the full-menu case, plus a warning when the resolver marks
  the card needs_repair (failing auto-reloads) on overview/buy/confirm.
- Add-card path: with no card on file, 'Add funds' becomes a guided screen —
  open the portal billing page, then 'I've added it — check again' re-fetches
  billing state and continues straight into the purchase (also recovers a
  transient display miss). Cards are never entered in-terminal.
- /subscription upgrade confirm names the exact card ('Visa ····4242 — the card
  on your subscription — will be charged'), best-effort via billing.state and
  only when the resolution rung matches what a subscription charge actually
  uses (subPin/customerDefault, mirroring Stripe's precedence); otherwise the
  generic line stands. Fail-soft: any lookup error keeps the generic line.
- Gateway serializes display/resolved_via/needs_repair; TUI ctx gains
  refreshState (topup) + fetchCard (subscription); new offline fixtures
  card-sub / card-repair.

Tests: TUI ctx mocks extended; CLI suites cover provenance + repair-warning
render, the Link guard, the add-card path (continue-after-recheck + abandon),
the sub-confirm card line, and keep the confirm-time lookup offline in tests.

* fix(billing): consume server canChangePlan, preserve distinct refusal codes, drop dead chargeability

- Parse canChangePlan verbatim from NAS payloads into BillingState and
  SubscriptionState; fall back to the legacy OWNER/ADMIN check only when the
  server omits the field (FINANCE_ADMIN stops being locked out where NAS
  authorizes it). Role model updated to the 5-role enum.
- Add the autoReload.card union (canonical | distinct | none) end-to-end:
  parse + gateway serialization, distinct carries payment_method_id/brand/last4
  with nullable display fields.
- stripe_unavailable (503, transient) and upgrade_cap_exceeded (429, daily cap)
  now survive to the wire as their own codes instead of collapsing into
  rate_limited; new exception types subclass BillingRateLimited so existing
  backoff call sites keep working.
- Remove card.chargeability / needs_repair parsing, serialization, fixtures and
  the cli warning blocks: NAS #670 removed the field, so the repair path was
  permanently dead. The future card-health signal belongs to the NAS W1/W3 work.
- Tests: five-role fixtures, canChangePlan override/fallback, all three
  auto-reload card variants, 429-vs-503 code preservation end-to-end.

* feat(tui): render the full NAS billing refusal surface

- billingOverlay: divergence notice when auto-refill charges a distinct card
  (portal deep-link to reconcile); needs_repair warnings removed with the field.
- topup: explicit copy for consent_required, org_access_denied,
  upgrade_cap_exceeded, auto_top_up_disabled_failures and stripe_unavailable
  (honors retry_after); processing_error is an explicit charge-failure case;
  transport loss during charge polling now reads as an unconfirmed outcome
  (check balance before retrying), matching the revocation path.
- subscriptionOverlay: branch on upgrade reason, not status, so an SCA-needing
  upgrade routes to portal verification even while NAS pre-#711 labels it
  payment_failed; after an upgrade, poll subscription state until the tier
  flips (bounded), rendering applying/still-applying rather than assuming
  immediacy.
- Capability-neutral refusal copy (owner, admin, or finance admin) replaces
  the stale org admin/owner wording.
- gatewayTypes: BillingAutoReload.card union added, needs_repair removed.

* refactor(shared): move terminal-billing wire types to @hermes/shared

The billing/subscription wire shapes (plus UsageBarData/UsageModelData,
which they reference) move verbatim from ui-tui/src/gatewayTypes.ts into
apps/shared/src/billing-types.ts so the desktop app can share the same
gateway contract. gatewayTypes.ts re-exports every moved name from the
new @hermes/shared/billing subpath, so no ui-tui consumer changes.

The subpath export keeps DOM-less ui-tui from pulling the barrel (whose
WebSocket helpers need the DOM lib). ui-tui also now declares its
@hermes/shared dependency explicitly instead of relying on workspace
hoisting.

* test(cli): pin nous_billing wire-layer status-to-exception mapping

The HTTP layer's error handling had zero coverage through _request:
only 2xx parsing and request shaping were tested, and the mapping cases
in test_remote_spending_gate_contract.py hit _raise_for_error directly.

Adds 19 tests driving _request via a monkeypatched urlopen: the
401-refresh-retry path (success, terminal plain/session_revoked,
idempotency-key preservation, base re-resolution), 403 variants through
the wire, 429/503 retry-after, non-JSON error bodies, 404/502
fallbacks, and URLError normalization.

Two behaviors are pinned as findings rather than fixed: a JSON-body
retryAfter hint is ignored unless the Retry-After header is present,
and a bare socket.timeout propagates uncaught (real urllib wraps
timeouts in URLError before this layer).

* fix(tui_gateway): delete dead credits.view RPC

The handler assigns into an undefined `usage` variable, so any call
would raise NameError (the except swallows the first hit, then the
return re-raises it uncaught). Nothing can reach it: the TUI command
registry removed /credits (pinned by test_credits_command_fully_removed)
and no client sends the RPC. The live credit view is
agent/account_usage.py::build_credits_view via the remote gateway's
/topup command, which is untouched.

* fix(cli): normalize read-phase timeouts to the typed billing error

urlopen wraps connect-phase timeouts in URLError (already mapped to
network_error), but a timeout during resp.read() raises a bare
TimeoutError that escaped the typed-BillingError contract and reached
callers as an unhandled exception. Catch it narrowly and normalize.
The boundary test now asserts normalization instead of documenting the
leak.

* fix(shared): stop typing mutation success payloads as error payloads

BillingMutationResponse.payload was declared BillingErrorPayload, but on
ok:true the gateway passes through the raw NAS success body (rail,
changeType, cancelAtPeriodEnd, ...). The TUI never reads it so nothing
broke, but the shared contract now feeds the desktop app too — widen the
field deliberately and document both shapes.

* feat(shared): typed billing refusal and charge-failure unions

- BillingRefusalCode covers every code the gateway serializes today, with a
  (string & {}) arm so unknown future codes (the NAS W3 card-health family)
  stay assignable — consumers keep their unknown-code fallback.
- ChargeFailureReason models the four NAS terminal reasons plus the raw
  subscription_payment_intent_requires_action code NAS leaks pre-#711.
- billing.state now carries the server-derived can_change_plan the gateway
  emits; capability comments updated (canChangePlan is capability-based, not
  an OWNER/ADMIN role gate).

* docs(billing): client-side billing state and refusal lifecycle table

Enumerates, from the code, every billing.state shape and typed refusal the
gateway serves and the exact TUI copy + recovery each renders. Acceptance from
the billing-integration handoff: no NAS billing state or typed refusal falls
through to a generic toast; unknown codes still degrade to the default branch
that surfaces the server message.

* refactor(desktop): consume @hermes/shared billing types, full refusal copy, divergence notice

- billing/types.ts becomes a re-export shim over @hermes/shared/billing (keeps
  the desktop-only bounds field via a local BillingAutoReload extension);
  needs_repair is gone with the shared type.
- resolveRefusal gains specific copy for consent_required, org_access_denied,
  upgrade_cap_exceeded, stripe_unavailable (transient, honors retry_after) and
  processing_error; BillingErrorKind now IS the shared BillingRefusalCode.
  Default fallback unchanged.
- Auto-refill row surfaces the distinct-card divergence: caption naming the
  charging card (or 'a different card' when brand/last4 are null) and a
  Reconcile portal deep-link instead of the inline edit form.
- Fixtures/tests updated for the required auto_reload.card union; new
  auto-refill-divergent dev fixture.

* fix(desktop): auto-refill-divergent fixture must be enabled to exercise the divergence row

* refactor(billing): explicit BillingTransient trait, drop broken credits.view, public token-cache invalidation

- BillingRateLimited / BillingStripeUnavailable / BillingUpgradeCapExceeded
  become siblings under a new BillingTransient trait (deterministic non-charge
  outcome, safe to retry) instead of the false is-a chain that made a Stripe
  outage 'a kind of rate limiting'. Catch sites that meant 'any deterministic
  pre-charge transient' now say so explicitly; the gateway serializer
  dispatches on the trait and emits the preserved raw code.
- Delete the credits.view RPC handler left broken by the /topup rename (its
  body referenced an undefined variable; no caller remains).
- invalidate_cached_token() replaces the CLI's reach into the private
  _token_cache global after a billing step-up.

* refactor(cli): extract CLIBillingMixin; charge gates follow the server capability

- Move the ~1,400-line billing/subscription handler family out of cli.py into
  hermes_cli/cli_billing_mixin.py, following the existing HermesCLI mixin
  pattern (lazy cli imports, verbatim bodies).
- can_charge and the CLI billing-action gates now route through
  can_change_plan (server capability with legacy role fallback) instead of the
  deprecated 3-role is_admin — a FINANCE_ADMIN the server authorizes can now
  add funds, matching the plan-change path.
- Render the spend bar from the UsageBar model's fill_fraction instead of the
  deleted _billing_spend_bar re-derivation; fix a stale docstring.

* refactor(tui): promote useMenu to overlay primitives, type pendingTierId end-to-end

- useMenu (arrow/number/Enter/Esc menu hook) moves to overlayPrimitives with
  an onKey escape hatch; billingOverlay's Overview and Limit screens drop
  their verbatim copies. BuyScreen keeps its bespoke handler (typing mode +
  stale-selection clamp don't fit the shared contract cleanly).
- SubscriptionResult carries pendingTierId directly; the shadow
  SubscriptionResultWithPending interface and the ResultScreen cast are gone,
  so the apply-poll field is type-tracked through finish().

* docs(billing): correct the CLI-parity row — the CLI has the full in-terminal change flow

* refactor(shared): move terminal-billing wire types to @hermes/shared

The billing/subscription wire shapes (plus UsageBarData/UsageModelData,
which they reference) move verbatim from ui-tui/src/gatewayTypes.ts into
apps/shared/src/billing-types.ts so the desktop app can share the same
gateway contract. gatewayTypes.ts re-exports every moved name from the
new @hermes/shared/billing subpath, so no ui-tui consumer changes.

hoisting.

urlopen wraps connect-phase timeouts in URLError (already mapped to
network_error), but a timeout during resp.read() raises a bare
TimeoutError that escaped the typed-BillingError contract and reached
callers as an unhandled exception. Catch it narrowly and normalize.
The boundary test now asserts normalization instead of documenting the
leak.

* fix(shared): stop typing mutation success payloads as error payloads

BillingMutationResponse.payload was declared BillingErrorPayload, but on
ok:true the gateway passes through the raw NAS success body (rail,
changeType, cancelAtPeriodEnd, ...). The TUI never reads it so nothing
broke, but the shared contract now feeds the desktop app too — widen the
field deliberately and document both shapes.

* feat(shared): typed billing refusal and charge-failure unions

- BillingRefusalCode covers every code the gateway serializes today, with a
  (string & {}) arm so unknown future codes (the NAS W3 card-health family)
  stay assignable — consumers keep their unknown-code fallback.
- ChargeFailureReason models the four NAS terminal reasons plus the raw
  subscription_payment_intent_requires_action code NAS leaks pre-#711.
- billing.state now carries the server-derived can_change_plan the gateway
  emits; capability comments updated (canChangePlan is capability-based, not
  an OWNER/ADMIN role gate).

* feat(shared): closed Known* halves for the refusal and charge-failure unions

- KnownBillingRefusalCode / KnownChargeFailureReason are closed literal sets,
  so classification tables, copy maps and tests can be Record-exhaustive and
  break at compile time when a code is added but not mapped. The wire types
  keep the (string & {}) open arm for unknown future codes.
- Add network_error (client-originated transport code the gateway already
  serializes) to the known set.
- Export the union types from the root barrel alongside the other billing
  names.

* feat(shared): canonical billing refusal policy and charge-settlement driver

- billing-policy.ts: one exhaustive Record<KnownBillingRefusalCode,
  BillingRefusalPolicy> classifying every known code (recovery kind,
  mid-poll ambiguity, idempotency-key reuse) with a documented unknown-code
  fallback. Surfaces keep their own copy; the behavior classification now
  has a single home that breaks the build when a new code goes unmapped.
- charge-settlement.ts: the settlement poll state machine (2s cadence,
  5-minute cap, bounded retry-after backoff, ambiguous-on-revocation) as a
  pure dependency-injected driver returning a discriminated outcome.
- The TUI's pollCharge becomes a thin renderer over the shared driver —
  byte-identical output, and the desktop poller can now share the same
  machine instead of a drifting copy.

* fix(desktop): real auto-reload bounds, shared refusal policy and settlement driver

- Delete the phantom BillingAutoReload.bounds plumbing: nothing ever populated
  it, so the auto-reload amount validation it fed was silently dead. The
  editor and validators now enforce the gateway's real top-level
  min_usd/max_usd (new test pins the $10 minimum actually rejecting), and
  types.ts collapses to a plain re-export shim over @hermes/shared/billing.
- Delete the test-only BillingRpcResponse envelope family; BillingResult is
  the one response model.
- Refusal copy speaks desktop: reconnect/sign-in route to Settings → Gateway
  instead of the TUI's /portal command; the dead processing_error refusal
  case is gone (it is a charge-failure reason, already rendered by the
  poller).
- Adopt @hermes/shared billing-policy + charge-settlement: the poll loop is
  the shared driver, revocation-ambiguity comes from the policy table
  (insufficient_scope mid-poll now counts, per the ruling), and all
  policy-retry codes back off during polling instead of failing hard.
  errors.test.ts is Record-exhaustive over KnownBillingRefusalCode again.

* refactor(shared): move terminal-billing wire types to @hermes/shared

The billing/subscription wire shapes (plus UsageBarData/UsageModelData,
which they reference) move verbatim from ui-tui/src/gatewayTypes.ts into
