Summary

One generic safe reply document, one existing publication owner, one small adapter seam, provider-specific presentation entirely at the edges.

  • Reply seam (ironclaw_extension_contracts::reply): a provider-neutral, bounded-by-construction ReplyDocument (display text, reasoning summaries, activities, attention, attachments, terminal outcome — never raw prompts, tool args/results, credentials, or chain-of-thought), monotonic ReplyRevisions, and one ReplySink::reconcile(revision, target, previous checkpoint) → outcome + checkpoint + evidence method. ReplyTransport is cadence only: stream hears every reconcile point, message the terminal one.
  • One publication owner: DeliveryCoordinator itself. There is no separately constructed publication service — composition calls start_reply_publication once, and registration, terminal resume, settlement waits, the boot sweep, and shutdown are coordinator methods over a private delivery_coordinator::publication module (per-target workers, coalescing, retries). The coordinator is also the process-journal observer. Publication state lives as a substate of the existing outbound attempt aggregate (lease + fence, monotonic desired/published revisions, opaque sink checkpoint, bounded provider evidence, one-way settlement) behind the store's guarded CAS operations.
  • Correct durable order, test-pinned: provider-independent preparation (channel/sink resolution, stored reply context, disclosure + gate-prompt enrichment, terminal attachment materialization) happens before the atomic claim; the claim is taken immediately before egress; the newest desired revision is persisted under the fence before the sink is called; the sink call is bounded by a timeout clamped to the lease TTL so expiry can never produce two simultaneous provider calls.
  • Real restart recovery: the journal's terminal commit is acknowledged only after the run's open publications have workers again (an error leaves the durable cursor unacknowledged and the journal redelivers), and a boot-time resume_reply_publications sweep over the existing outbound tenant index covers a crash after the acknowledgement. Every crash window in the design doc §5 is covered by a test.
  • Fail-closed ambiguity (Slack, keyed to what docs.slack.dev documents): an ambiguous chat.appendStream is resolved by conversations.replies read-back before anything else is appended — landed advances the checkpoint, not-landed re-sends only the missing delta, and an unreadable read-back for a text-carrying pending stays Ambiguous and is never re-sent. An ambiguous chat.startStream (no idempotency key, no documented way to locate the stream) marks the checkpoint: no second stream is ever opened and the terminal text is never posted conventionally beside a possible ghost; the host settles Unknown.
  • Unauthorized is fail-closed by the existing auth architecture (.claude/rules/lifecycle.md): the sanitized failure and checkpoint are persisted and the publication settles Failed(AuthorizationRevoked); credentials are restored through the extension's ordinary reconnect/setup flow, and the contract no longer claims automatic re-auth.
  • Edges: Slack renders the document on the native Agent surface (agents.sessions.setStatus, chat.startStream/appendStream/stopStream, timeline task cards, attention → suspended, stop + title events, rate-limit hints, versioned private checkpoint). The canonical importable app manifest ships as crates/extensions/packages/slack/app_manifest.json; the docs page embeds a test-pinned identical copy. WebUI's ProjectionReplySink converts revisions into the existing live projection items over SSE/WebSocket, with reconnect/history from the existing durable projections (no reply journal exists). Telegram is terminal-only with checkpoint-keyed idempotency and OUT-7 held across lease takeovers.
  • Surface reduction this pass: ReplyPublicationService / ReplyPublicationDeps / ReplyPublicationCommitObserver and the runtime's parallel field/getter/shutdown deleted; RunDeliveryServices and ChannelWorkflowDeliveryServices carry only the coordinator; ReplyProjectionObserver folded to pub(crate); dead contract vocabulary deleted (activity_progress, ReplyActivityState::{Running, Killed}, ReplySinkOutcome::retry_after, ReplyPhase::as_str) and the contracts size ceiling re-pinned down (12 896 → 12 867), with the struct test-support ratchet baselines also shrunk (the coordinator handle became ungated production state). Composition stays within its mass budget without any ratchet raise.

Review-driven correctness pass (all eleven IronLoop threads addressed, each behind a sabotage-verified or red-first test):

  • The canonical app manifest no longer subscribes to the legacy assistant_thread_started / assistant_thread_context_changed events (Slack's live Agent View validator rejects them); the lockstep test pins their absence, and the payload parser keeps compatibility arms for older installs.
  • A native Agent Stop for a top-level DM resolves the run's own TOPIC-LESS conversation binding (the session thread rides only the reply context) — previously the thread_ts topic fingerprinted a different conversation and Stop found nothing to cancel. Covered by a payload test and an end-to-end journey asserting the stop command carries the DM run's thread id.
  • WebUI reasoning: the projection checkpoint now tracks the open tail segment's fingerprint (not just the segment count), so in-place-grown reasoning deltas and the closing replacement republish under one stable thinking-item id — with a no-duplicate case.
  • Reply context is snapshotted per run at target registration and persisted on the durable descriptor; the worker and every resume publish with that snapshot, so a newer DM overwriting the latest-wins per-conversation store can never re-thread an older run's reply (race regression test + resume-uses-snapshot assertion).
  • Slack attachments track per-file confirmed progress in the checkpoint, and an ambiguous files.completeUploadExternal latches attachment_upload_ambiguous: nothing is ever re-uploaded, and the publication settles Unknown instead of possibly doubling files.
  • A failed run produces exactly ONE terminal user-visible reply: the publication's terminal document carries the failure summary, and the observer posts the conventional RUN_FAILED_MESSAGE only when no publication actually delivered — covered at the observer contract tier (both directions) and by a wire-level journey (stream closes with the failure copy once; no chat.postMessage duplicate).
  • An ambiguous outcome with no checkpoint anywhere settles Unknown after a single attempt (a retry would blindly repeat the exact provider side effect — a first Telegram send can no longer double).
  • RecoveryRequired terminal commits (terminal in the process contract) now resume orphaned publications like any other terminal status, rendered as a failed reply.
  • An ambiguous no-text chat.stopStream is verified by its own re-send: message_not_in_streaming_state on the retry proves a close landed, and the revision applies instead of failing permanently.
  • Gate attention works from what production actually emits: the loop announces only GateBlocked { kind } (the ref-carrying milestone has no production caller), so enrichment resolves the gate ref from the run's durable state — and the e2e harness's scripted milestones were made production-faithful, turning the existing 50+ gate journeys into the regression proof.

Composed-runtime verification pass (the ironclaw_composition suite, 957 tests, is green — it caught three branch regressions its earlier runs had not reached):

  • The composition session-channel test fixture had been flipped to bind a fake reply sink, so every composed runtime built with it had no live reply publication at all (SSE showed only durable run status plus the finalized answer). The fixture now mirrors the binary's exact shape — delivery-only surfaces plus with_session_reply_channel — so composition attaches the real ProjectionReplySink and the composed webui_v2_e2e SSE journeys exercise the production wiring end to end.
  • The answer's first visible text is now a ControlCritical reconcile point: a fast run reaches its terminal commit inside the 250 ms progress-pacing window, and pacing the first text away jumped the stream from "working" straight to the finalized answer (message transports are unaffected — they only hear Terminal).
  • The pacing sleep is now wake-responsive (select! on the target's wake): a revision arriving mid-window re-evaluates its reconcile point immediately instead of deafly waiting the window out — without this, an early activity revision could swallow the first-text wake entirely. Both behaviors are pinned by a red-first worker test; the previously-flaky composed SSE ordering test now passes 10/10.
  • The composition manifest-parity test's expected Slack egress list was extended with the native Agent endpoints the manifest (and the Slack package's lockstep test) already pin.

Review triage pass (2026-09-02) — every thread and body finding from CodeRabbit (five passes), IronLoop, the two multi-agent reviews, the structural review, and the approach audit was re-verified against the head; the valid, non-over-engineered ones were fixed, each behavior change behind a red-first test.

  • Crash recovery read the wrong mount. /outbound is a per-user alias and every channel run is scoped to its actor, but both recovery paths rebuilt the scope with TurnScope::new (system user): the journal observer read an empty subtree and keyed a run nobody registered, and the boot sweep did the same. The observer now rebuilds the scope through the kernel's own turn_scope_from_process_scope and the sweep carries the deployment actor; the publication harness scope carries its owner like production, which turns the two journal-recovery pins red without the fix. Runs owned by other users (multi-user hosted deployments) resume via the journal, not the sweep — documented inline.
  • Reply document / projection. activity_finished honours first-terminal-wins (a late finish minted a revision the store could never advance to); apply_terminal_facts is idempotent for a terminal document; a failed model call's partial text is discarded when the call is retried (the reply read Wor\n\nWorld); shared audiences never see activity input/output previews; a failed run's terminal reply carries the neutral per-category copy through the kernel type's accessors — the model-visible failure detail no longer reaches Slack or Telegram.
  • Publication lane. A channel that disappears mid-publication settles Failed(Rejected) after the terminal budget instead of polling forever; the worker plans each wake from a local mirror and reads the row only when a reconcile is due (forty paced wakes cost ≤2 reads, forty without the mirror — sabotage-verified); the settlement wait watches the local worker instead of scanning the thread every 25 ms; the sink call is bounded by the claim's remaining lease; the descriptor persists the seam-bounded reply context; shutdown awaits an aborted worker before releasing its lease; the checkpoint a sink hands back with a Permanent/Unauthorized report now lands on the settled row (the comment claimed it already did); a lapsed lease skips the provider call and retries (then fails closed under the budget) instead of reading a zero timeout budget as an ambiguity that settled Unknown with no provider call; one advance builder and one step handler replace three copies and two.
  • Slack sink. One forget_presentation reset (the rewrite path had kept the plan-title key, so a re-presented stream opened without its header); unreadable 2xx answers arm the same pending/ghost-stream latches as transport loss; a read-back without a messages array proves nothing instead of re-sending; the terminal note is checkpointed; ticket/byte-upload transport faults are retryable while only files.completeUploadExternal latches the attachment ambiguity; an unauthorized read-back is Unauthorized, not an ambiguity retried until the budget lapses; read-back proves a pending delta only past the already-applied text; the unused agents.sessions.rename grant is gone and the lockstep test now checks declared ⊆ inventory.
  • WebUI. A locally stopped run that completes anyway retracts its "Stopped" notice and converges its answer; the fence is one gate per ingress instead of eleven inline checks; a locally stopped run's final_reply passes the fence and lifts the stop (it is the backend's evidence the cancel lost — before, a reply that outran the projection status was discarded and the notice stayed); the stopped-notice id is a shared constant; new pins for two runs streaming in one thread, in-place reasoning republish, and the typed-frame fence.
  • Outbound publication substate. The store contract now proves what its docs claimed: two store instances racing the lease claim yield exactly one Acquired and one Held (a CAS version miss converges), a backend without versioned CAS fails the claim closed without touching the row, the tenant-wide open listing never crosses tenants that share agent/project/thread ids, attempt-level rewrites keep the substate, the descriptor (reply context included) round-trips through a libSQL reopen, and the advance pre-checks reject a terminal revision below the published one. The open listing drops settled rows page by page instead of retaining every tenant row until the sort. The shared sink conformance drive derives the terminal attachment refs from the files the request materializes and adds one negative step: an unreadable checkpoint is never evidence the terminal was applied.
  • Docs and guidance. Guidance and docs describe the seam that ships (every declared [channel.reply] binds one ReplySink; the session channel's sink is the projection sink composition attaches; attachments materialize inside reply publication), the two 2026-08 channel design records carry superseded-in-part banners, the Slack rows say stream replies, and the unused rename link is gone. The RebornRuntime delivery-coordinator accessor is test-support again (production wiring takes the coordinator from the factory) with the struct ratchet re-pinned 267 → 268 / 43 → 44 against main's 269 / 44; the binary's session-reply-channel naming is pinned by a CLI test; stale comments and misplaced doc blocks are corrected.
  • Riders carried by the last authoring commit (called out, not split): dynamic OAuth client re-registration on an unreadable/stale-callback record plus the SecretMaterialUnreadable secret-store variant (auth resume after a key rotation or callback move; user credentials stay fail-closed), the incarnation-id backfill on legacy installation rows (hosted-MCP checkpointing), and one capability-policy prompt sentence (the seven golden snapshots). Each is test-pinned; the DCR log lines are now debug! and a malformed-record test was added.

Deliberately not done (product decisions or over-engineering): a terminal guard on finalize_answer (the canonical transcript must replace streamed text even after the terminal outcome — test-pinned, so the repeated-facts case is bounded by the idempotent apply instead); a DM Agent Stop is normalized topic-less to match a top-level DM message, but a threaded DM follow-up binds with the thread as topic, so a Stop pressed during a follow-up run finds nothing — reconciling the two needs a decision on DM thread identity (bind DM thread replies topic-less, or stop both bindings); deriving the session-reply channel from the manifest instead of the binary naming it; the mirror-struct consolidations; a per-user boot sweep enumeration; the browser-side stream assertion in the Slack channel journey (that journey runs in the post-merge coverage workflow, not the PR gate; the behavior is pinned on the recorded wire at the integration tier); the Postgres leg of the new outbound contract suite (needs new dev-dependencies in the crate — the existing dual-backend parity suites still cover the store). Smaller deferrals, each answered in its thread: the observer's delivery permit held across the settlement wait; eviction of target-less terminal runs from the projection (bounded by the 4,096-run cap); a caller-level test for the SecretMaterialUnreadable → Unavailable mapping; private ReplyDocument fields with a validating Deserialize (no production path deserializes one today); the O(k·n) answer fold (128 KiB cap). Also deferred: rejecting or flagging attachment lists above the 16-attachment document bound (the extras are dropped at finalize_answer today; a truncation marker is a contract addition); a tenant-wide boot sweep across owners; a status-indexed open-publication query.

Live-validation fixes (2026-09-02) — four presentation defects reproduced on the live head, each fixed at its owning seam with a behavior-level regression test:

  • WebUI hid a text-only answer such as 19.. The transcript held the finalized record, but the Markdown renderer turned a line holding only an ordered-list marker into an empty <ol>. The renderer now escapes a bare marker outside code fences (markdown.ts), tracking the opening fence's delimiter and width the way CommonMark closes fences; real lists and fenced code are untouched. Rendered-output tests, including a fence containing the other delimiter.
  • WebUI exposed complete tool outputs. The activity card's Result tab rendered the bounded output_preview; the card now shows Details, Parameters, and Error only. The output stays on the durable record for diagnostics and channel flows. Rendered-card test; the dead result renderer and its two strings are gone.
  • Slack drew an empty timeline bullet. The plan opened every stream with a hidden-title sentinel task so a lone plan_update would render; Slack hides the title and keeps the bullet. The sentinel is deleted: the plan header rides only with real task cards, a stream opens only once the document holds renderable content, and the session status alone carries the thinking state of a tool-less run.
  • Slack broke paragraphs at token boundaries. The stream runs in chunks mode (Slack forbids mixing markdown_text with chunks, and a stream keeps its opening mode), and Slack renders every markdown_text chunk as its own block. Progress text is now published by whole paragraph (blank line outside a code fence), a paragraph past SLACK_TEXT_HOLD_MAX_CHARS flushes at its last sentence end, and the terminal, a finalized canonical answer, or a new attention block flushes everything held. The journey suite's exact stream sequences were re-derived for these rules; the design doc's Slack section describes them.

An existing Slack installation will not change itself: an administrator must apply the updated app manifest (the agent_view feature is irreversible per Slack) and reinstall/reauthorize the app.

Compatibility & rollback

  • Persisted [channel.reply] wire shape unchanged; the publication substate is a serde-defaulted addition to the attempt row — older readers ignore it, rows without it behave as one-shot sends.
  • The journal observer keeps its durable cursor id (reply-publication-commit-observer-v1), so the fold does not replay or orphan an existing cursor.
  • Reverting the branch restores the previous reply paths; the Slack agent_view manifest change is the one irreversible external step and is documented as the administrator's.

Test Strategy

  • Unit/contract: cargo test -p ironclaw_extension_contracts (reply vocabulary, cadence, conformance) · cargo test -p ironclaw_outbound --all-features (publication substate guards incl. concurrency, cross-tenant isolation, and the tenant-wide open listing; the new contract suite runs in-memory + libSQL, the existing parity suites cover Postgres) · cargo test -p ironclaw_assistant (projection; publication cadence/retry/ambiguity/unauthorized; ordering-and-recovery suite: desired-before-egress — sabotage-verified, prep-before-claim, lease-clamped sink timeout, boot sweep with no journal signal, awaited journal acknowledgement, stable observer id; observer cutover suites) · cargo test -p ironclaw_slack_extension (fake Agent API incl. ghost-stream and unreadable-read-back cases — sabotage-verified; manifest lockstep against the canonical file) · cargo test -p ironclaw_telegram_extension.
  • Integration: cargo test -p ironclaw_integration_tests --test reborn_integration_extension_delivery --test reborn_integration_delivery_user_journeys (libSQL + Postgres legs, Docker via colima) — a signed Slack event becomes a run whose reply streams through the native Agent wire; cross-channel journey.
  • Channel host + edges: cargo test -p ironclaw_extension_host -p ironclaw_telegram_extension (690 tests incl. the scripted channel-host journeys) · WebUI frontend lint + typecheck + vitest run (stop-notice retraction, two-run streaming, in-place reasoning republish, typed-frame fence).
  • Live-validation fixes: cargo test -p ironclaw_slack_extension (plan-level pins: empty document plans nothing, header with the first real task, paragraph publication with fences and the hold bound; 40 agent-API journeys on the new stream sequences) · WebUI vitest run (rendered 19. and list/fence cases; rendered tool card without a Result tab).
  • Composed runtime: cargo test -p ironclaw_composition (957 tests) — the full-build webui v2 e2e suite incl. both SSE progressive-text ordering journeys (live text observable before terminal completion) and the first-party manifest parity suite.
  • Architecture: cargo test -p ironclaw_architecture_tests (layer/edge gates, ceilings re-pinned down) + composition budget + pre-commit safety.
  • Workspace: cargo fmt clean, cargo clippy --all --benches --tests --examples --all-features -- -D warnings clean.
  • Not run: the browser E2E suite under tests/e2e/ (needs the provisioned local stack + python deps; the Slack channel journey there is in the post-merge coverage workflow, not the PR gate) and anything against a live Slack workspace — the manifest apply/reinstall is the external administrator step.

Walkthrough

This change replaces ChannelReply with ReplySink, adds bounded reply projection, persists publication state on outbound attempts, introduces fenced publication workers, and implements Slack Agent streaming and Telegram terminal replies. It also fixes DCR re-registration, classifies unreadable secret material, backfills installation incarnation ids, tightens a capability-usage prompt, and adds a chat "run stopped" UI notice plus unrelated tool-result/markdown UI cleanup.

Changes

Reply publication architecture

Layer / File(s) Summary
Reply contracts and binding
crates/contracts/ironclaw_extension_contracts/..., crates/contracts/ironclaw_product_contracts/..., crates/extensions/ironclaw_extension_host/...
ReplySink owns reply reconciliation. ReplyTransport selects stream or terminal cadence. A declared reply surface requires a bound sink.
Persisted publication state
crates/domains/ironclaw_outbound/...
Delivery rows carry optional publication state with leases, fences, checkpoints, revisions, evidence, settlement, and crash-recovery operations. Legacy one-shot rows keep the old shape.
Projection and coordinator
crates/product/ironclaw_assistant/..., crates/app/ironclaw_composition/...
The assistant builds bounded reply documents, publishes revisions through DeliveryCoordinator, resumes open publications, and attaches the product projection sink to the configured session channel.
Slack and Telegram sinks
crates/extensions/packages/slack/..., crates/extensions/packages/telegram/...
Slack reconciles native Agent streams with read-back and durable checkpoints. Telegram renders terminal documents through its shared message path with idempotent checkpoints.
Validation and integration coverage
crates/product/ironclaw_assistant/tests/..., crates/extensions/packages/*/tests/..., tests/integration/...
Tests cover contract validation, publication ordering, lease recovery, provider ambiguity, attachment handling, Agent events, stream delivery, and terminal reply behavior.

Auth DCR recovery and secret material handling

Layer / File(s) Summary
DCR re-registration
crates/domains/ironclaw_auth/src/engine/dcr.rs, crates/domains/ironclaw_auth/tests/auth_engine_contract.rs, docs/internal/reborn/contracts/auth-product.md
The engine re-registers a dynamically registered OAuth client when its record is unreadable or its callback URI is stale. It no longer fails the flow in these cases.
Secret material classification
crates/substrates/ironclaw_secrets/..., crates/kernel/ironclaw_host_runtime/src/egress/credential.rs, crates/kernel/ironclaw_host_runtime/src/services/tests.rs, crates/product/ironclaw_assistant/src/admin_user_directory.rs
SecretStoreError gains a SecretMaterialUnreadable variant. This variant maps to a stable BackendUnavailable reason across credential sanitization and error mapping.
Installation incarnation backfill
crates/extensions/ironclaw_extension_registry/...
A legacy v2 installation record missing an incarnation id gets one backfilled during lifecycle mutation.

Capability usage policy guardrail

Layer / File(s) Summary
Provider-evidence claim guardrail
crates/contracts/ironclaw_loop_contracts/prompts/capability_surface_usage_policy.md, crates/kernel/ironclaw_turns/tests/agent_loop_host_contract.rs
The prompt now forbids the model from claiming a live provider check unless the capability actually ran in the current turn.

WebUI run-stopped chat notice

Layer / File(s) Summary
Local stop fencing and stopped notice
.../pages/chat/hooks/useChat.ts, .../lib/useChatEvents.ts, .../lib/useHistory.ts, .../lib/run-tracking-state.ts, .../lib/message-types.ts, .../i18n/*
The client fences buffered live frames for a locally stopped run. It appends a client-only "Stopped" system message. It preserves this message across history merges. Locale packs add the chat.runStopped string.

Tool-result and markdown UI cleanup

Layer / File(s) Summary
Tool result removal and markdown fix
.../components/tool-activity.tsx, .../lib/markdown.ts, .../i18n/*
The tool activity card drops the result tab. Markdown rendering keeps bare numeric sentences visible instead of collapsing them into empty lists. Locale packs drop the unused tool.tabResult/tool.resultAlt keys.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟠 High · up to 4bcdc

This PR introduces durable progressive replies across Slack, Telegram, and WebUI, but unresolved paths can duplicate or lose user-visible replies, omit files, strand publications after restart or shutdown, or leave runs incorrectly marked stopped; merge should wait for these correctness and recovery risks to be fixed or explicitly accepted.

…tion seam

The extension-host crate's own test modules were never updated for two
contract changes that landed with progressive reply publication, so
`cargo clippy --all --all-features` was red on this crate alone:

- `RunDeliveryServices` / `ChannelWorkflowDeliveryServices` traded
  `project_filesystem` for `reply_publication` (the run's answer is
  published, not sent by the observer). Four literals now build the
  service from the same kernel-backed ports production wires —
  `KernelTerminalReplyFacts` over the scripted turn coordinator and
  thread service, `TurnCoordinatorStopRequester` — rather than a double.
- `ResolvedChannelDelivery` gained `generation`; the three
  deployment-bound test resolvers report 0.

The suite's fake Slack server also only spoke `chat.postMessage`. Slack
declares `[channel.reply] transport = "stream"`, so the answer now rides
the native Agent stream: added `agents.sessions.setStatus`,
`chat.startStream` / `appendStream` / `stopStream`, and
`conversations.replies` handlers with the documented response shapes,
plus stream recorders beside the postMessage ones.

KNOWN RED, handed off: ten `channel_host::e2e_tests` Slack DM scenarios
still assert the run's answer, the working indicator, and gate prompts
as `chat.postMessage`. Under stream transport those live inside the
published reply document, so the assertions need the same port already
applied to `tests/integration/extension_delivery.rs`. Verified that the
gate route survives the cutover: `record_gate_route_if_needed` still
writes the source-conversation fingerprint when no prompt message is
delivered, so a bare "approve" in the thread resolves the gate on a
stream channel.

…xt slices

The pre-commit UTF-8 check flags every `&text[..n]`. All three sites in
the reply vocabulary walk `end` back to a char boundary immediately
above the slice, so they are correct as written and only needed the
`// safety:` note the check asks for. No behavior change.

…gent stream wire

The ten channel_host::e2e_tests scenarios handed off KNOWN RED still
asserted the run's answer, the working indicator, and gate/auth prompts as
chat.postMessage. Slack declares [channel.reply] transport = "stream", so
those now live inside the published reply document on the native Agent
surface, and the suite asserts that wire:

- gate/auth prompts are the streamed attention block, with the message
  path's copy (approval reply instruction; auth headline plus the
  private-DM setup link, stripped for a Shared channel audience), published
  exactly once even when a gate-resolution ack races the live delivery
  loop;
- working state is the agent session status (processing -> suspended ->
  processing) instead of a posted-then-deleted indicator message, renamed
  slack_dm_streams_working_state_and_closes_the_stream_after_final_reply;
- final replies ride the single chat.stopStream close, never a plain post,
  and nothing is ever retracted because no notice message existed.

To reach that wire, the scripted RecordingTurnCoordinator now publishes the
loop milestones (IterationStarted / ModelStarted / Blocked / Completed)
into ONE ReplyProjection shared with the harness's ReplyPublicationService
- the stand-in for the loop host's ReplyProjectionMilestoneSink, exactly as
append_final_assistant_message already stands in for the loop's transcript
finalization - and test_reply_publication wires the real
GateAttentionEnricher over the same blocked-auth prompt source the observer
consults, mirroring composition. TurnMode::Complete deliberately stays
milestone-free: it is the recovery shape whose terminal reply exercises the
sink's conventional post (the still-green fast-path tests pin it).

FakeAuthChallengeProvider::assert_calls(n) replaces assert_single_call: a
stream channel fetches the challenge twice per gate by design (the
observer's serviceability decision plus the publication's attention
enrichment), never once per poll; the triggered-prompt path stays at one.

The bare-approve journeys keep pinning that record_gate_route_if_needed
records the source-conversation fingerprint when no prompt message is
delivered (bare_approve_in_dm_resolves_gate_recorded_by_observer), so a
bare threaded "approve" still resolves the gate on a stream channel.

cargo test -p ironclaw_extension_host --lib: 491 passed, 0 failed (was
481/10); crate clippy --all-targets --all-features clean; the four
race-sensitive scenarios re-run 8x without flakes. Design doc S11 gains the
evidence row.

The pre-commit ARCH-SPRAWL checker requires a literal `plan #NNNN` in every
arch-exempt annotation; the five waivers introduced with progressive reply
publication cited the design-doc path instead. All five now cite #8007
(progressive reply publication: decomposition and aggregation follow-ups),
which lists each site and the refactor that discharges it:

- reply_publication/worker.rs        too_many_args (PublicationWrite bundle)
- extension_contracts channel_adapter.rs  optional_arc (ChannelSurfaces.reply)
- extension_contracts channel.rs     large_file
- extension_host channel_host.rs     large_file
- assistant projection/tests/runtime_stream.rs  large_file

…sting owners

Course-correction of the reply architecture on this branch (PR #8006):
one projection owner, one publication owner, one seam - no parallel
subsystems, no host-owned reply mode.

- contracts: ReplyDocument now evolves only through bounded semantic
  mutators; ReplyChange/ReplyChangeClass/ReplyId and the apply reducer
  are deleted. ReplySinkReport keeps the opaque checkpoint plus neutral
  provider evidence (refs, read-back verification, outcome).
- outbound: renew_reply_publication_lease deleted - a same-owner claim
  re-entry extends the lease and doubles as the heartbeat. Claim/fence,
  monotonic revisions, evidence, and one-way settlement are unchanged.
- assistant: reply_projection.rs -> projection::reply (a submodule of
  the existing projection owner); reply_publication ->
  delivery_coordinator::publication (service + private worker +
  kernel_ports free functions). The coordinator remains the attempt
  aggregate's sole writer via its guarded store-op methods.
- composition/binary: host_owned_reply and bind_host_owned_reply_sinks
  deleted; the binary names the deployment's session-reply channel
  (with_session_reply_channel) and composition attaches
  ProjectionReplySink through the ordinary surfaces.reply slot - no
  marker flag, nothing downstream distinguishes host-supplied sinks.
- architecture: contracts size ceiling re-pinned 12_928 -> 12_896
  (a tightening; measured post-consolidation).
- tests: suites ported to the mutator interface; extension_delivery
  regains a citable assert_slack_thread_delivery_evidence so the
  journey-evidence contract asserts the Agent-stream wire.
- docs/guidance: design doc, outbound README, root AGENTS.md, and
  extension/slack guidance updated to the consolidated owners.

Behavior preserved: Slack Agent stream lifecycle, Telegram terminal
replies, WebUI live progress, claim/fence takeover, evidence-gated
settlement (ambiguous -> Unknown, never blind-retried).

…d fix its durability order

One publication owner: the separately constructed ReplyPublicationService
(and its Deps bundle, crate-root re-export, runtime field/getter, parallel
shutdown, and the dual-handle service structs) is gone. Composition calls
DeliveryCoordinator::start_reply_publication once; registration, terminal
resume, settlement waits, the boot sweep, and shutdown are coordinator
methods over the private publication module, and the coordinator itself is
the process-journal observer (same durable cursor id).

Correctness fixes the fold carries:
- Worker order: provider-independent preparation before the claim, the
  claim immediately before egress, the desired revision persisted under
  the fence before the sink call, and the sink timeout clamped to the
  lease TTL so expiry cannot double provider calls.
- Restart recovery: the terminal journal commit is acknowledged only after
  recovery ran (errors redeliver), plus a boot sweep over a new
  list_open_reply_publications tenant-index store read for the
  crash-after-acknowledgement window.
- Slack ambiguity fail-closed per current Slack docs: an ambiguous
  chat.startStream marks the checkpoint and never opens a second stream
  nor posts the terminal text beside a possible ghost; an unreadable
  read-back for a text-carrying pending stays Ambiguous and is never
  re-sent.
- Unauthorized settles Failed(AuthorizationRevoked) fail-closed per
  lifecycle.md, and the contract doc says so instead of claiming re-auth.

Surface reduction: ReplyProjectionObserver folded to pub(crate); dead
reply vocabulary deleted (activity_progress, ReplyActivityState::
{Running,Killed}, ReplySinkOutcome::retry_after, ReplyPhase::as_str) with
the contracts ceiling re-pinned down 12_896 -> 12_867; the importable
Slack app manifest is now the canonical package file app_manifest.json
with the docs copy test-pinned identical; stale reply-journal comments
corrected. Integration harnesses defer the build's publication start
(test-support flag) so the one start carries the group's kernel handles.

New coverage: publication ordering-and-recovery suite (desired-before-
egress sabotage-verified, prep-before-claim, lease-clamped timeout, boot
sweep with no journal signal, awaited acknowledgement, stable observer
id), the tenant-wide open-publication listing conformance case, and the
two Slack ambiguity journeys (sabotage-verified).

… streaming

Review-driven correctness pass (all eleven IronLoop threads, each behind a
sabotage-verified or red-first test):

- Slack app manifest: drop the legacy assistant_thread_started /
  assistant_thread_context_changed subscriptions (Slack's live Agent View
  validator rejects them); the lockstep suite pins their absence and the
  payload parser keeps compatibility arms for older installs.
- Native Agent Stop for a top-level DM resolves the run's own topic-less
  conversation binding (the session thread rides only the reply context), so
  Stop cancels the active run instead of fingerprinting a conversation that
  does not exist; covered by a payload test and a wire-level journey.
- WebUI reasoning: the projection checkpoint tracks the open tail segment's
  fingerprint plus stable per-segment thinking ids, so in-place-grown
  reasoning republishes under one item instead of duplicating.
- Reply context is snapshotted per run at target registration and persisted
  on the durable descriptor; the worker and every resume publish with the
  snapshot, so a newer DM overwriting the latest-wins per-conversation store
  can never re-thread an older run's reply.
- Slack attachments track per-file confirmed progress and latch ambiguous
  files.completeUploadExternal outcomes: nothing is ever re-uploaded and the
  publication settles Unknown instead of possibly doubling files.
- A failed run produces exactly one terminal user-visible reply: the
  observer posts the conventional failure notice only when no publication
  actually delivered.
- A checkpoint-less Ambiguous outcome settles Unknown after a single
  attempt; RecoveryRequired terminal commits resume publications; an
  ambiguous no-text stopStream is verified by its own re-send; gate
  attention enrichment resolves the gate ref from durable run state (the
  loop announces only GateBlocked { kind }), and the e2e gate milestones
  were made production-faithful so the existing journeys pin it.

Composed-runtime pass (the ironclaw_composition suite caught three branch
regressions its earlier runs had not reached):

- The session-channel test fixture had been flipped to bind a fake reply
  sink; composed runtimes therefore had no live reply publication at all.
  It now mirrors the binary's exact shape (delivery-only surfaces plus
  with_session_reply_channel), so composition attaches the real
  ProjectionReplySink and the composed webui SSE journeys exercise the
  production wiring end to end.
- The answer's first visible text is a ControlCritical reconcile point: a
  fast run reaches its terminal commit inside the 250 ms progress-pacing
  window, and pacing the first text away jumped the stream straight to the
  finalized answer. Message transports are unaffected (Terminal only).
- The pacing sleep is wake-responsive: a revision arriving mid-window
  re-evaluates its reconcile point immediately instead of deafly waiting the
  window out. Both cadence rules are pinned by a red-first worker test.
- The composition manifest-parity expectation gained the five native Agent
  egress endpoints the manifest already declares.

Gates: the struct test-support ratchet baselines shrink (runtime.rs field
10->9, method 44->43; WS0 members 269->267) because the coordinator handle
became ungated production state; no ceiling was raised anywhere.

Correct the ExtensionBindings::channel contract comment.

The comment says an all-None ChannelSurfaces value is valid for authenticated-session ingress plus a stream reply. check_channel_halves now requires bound.reply for every declared [channel.reply]. State that only authenticated-session ingress is host-owned; a declared reply still requires ReplySink.

As per coding guidelines, update the owning contract/docs when behavior changes.

Update the Slack catalog row: its reply transport is no longer message.

Line 36 renames the seam to ReplySink, but the catalog row still labels Slack's reply half message [channel.reply]``. This PR moves Slack to [channel.reply] transport = "stream" — `crates/extensions/packages/slack/AGENTS.md` line 50 and the e2e comment at `crates/extensions/ironclaw_extension_host/src/channel_host/e2e_tests.rs` line 433 both name the stream transport. A reader routing work from this table will target the wrong transport.

Telegram's row (line 103) stays correct: the PR keeps Telegram terminal-only.

The guidance rules require verifying every concrete reference at write time and keeping the owning docs current when behavior changes.

Inline comments:
In `@crates/app/ironclaw_composition/src/runtime.rs`:
- Line 4421: Update the boot-recovery task spawned around
resume_reply_publications so RebornRuntime retains its JoinHandle or
cancellation handle, cancels it during shutdown, and awaits its completion
before calling shutdown_reply_publication. Ensure the task has a single
lifecycle owner and cannot resume publications or reacquire leases after
shutdown begins.

In `@crates/contracts/ironclaw_extension_contracts/README.md`:
- Line 33: Update the README’s shipped-module count to 21, calculated from pub
mod declarations excluding feature-gated test_support, and revise the channel
reply description so [channel.reply] binds reply::ReplySink via ChannelDelivery
rather than claiming stream replies have no adapter half; retain only the
statement that authenticated-session ingress is host-owned.

In `@crates/contracts/ironclaw_extension_contracts/src/reply.rs`:
- Around line 645-648: Track reasoning overflow explicitly by adding a
reasoning_truncated flag alongside activities_truncated and set it whenever
add/close reasoning paths in the reply implementation discard content due to
REPLY_MAX_REASONING_SEGMENTS or zero remaining capacity, including the
no-open-segment case. Expose and initialize the flag consistently so consumers
can distinguish complete reasoning from clipped reasoning while preserving
existing return behavior.
- Around line 768-771: Update clear_attention to check whether attention is
present before calling next_ordinal; return false without mutating
applied_changes when there is nothing to clear, and only allocate an ordinal and
perform the clear when attention exists.

In
`@crates/contracts/ironclaw_extension_contracts/src/test_support/conformance.rs`:
- Line 445: Update the terminal-step handling in the conformance flow to
preserve the existing checkpoint when the terminal ReplySinkReport returns None,
matching the stream branch’s fallback behavior. Ensure the checkpoint passed to
the repeated terminal reconcile remains the newly returned checkpoint when
present, otherwise the previously carried checkpoint.

In `@crates/contracts/ironclaw_extension_contracts/src/test_support/fakes.rs`:
- Line 261: Update RecordingReplySink::new to validate the generated provider
reference before the expect at the “provider ref within bound” assertion, and
return ChannelError::Render when the prefix and revision exceed ReplyProviderRef
limits. Preserve successful construction for valid references and remove the
panic path for invalid input.

In `@crates/contracts/ironclaw_extension_contracts/tests/reply_contract.rs`:
- Around line 431-451: Update block_on to use Waker::noop() with
Context::from_waker, removing the custom RawWaker/RawWakerVTable helpers and
unsafe Waker::from_raw construction while preserving the existing future polling
loop.

In `@crates/domains/ironclaw_outbound/tests/outbound_state_store_contract.rs`:
- Line 3221: Immediately above the #[allow(clippy::too_many_arguments)]
attribute, add an arch-exempt comment matching the required pattern, with a
concise one-line rationale and the applicable plan number; otherwise refactor
the affected function arguments into a small struct and remove the allow.

In `@crates/extensions/ironclaw_extension_host/src/channel_egress.rs`:
- Around line 334-337: Add a caller-level test for
HostRuntimeChannelEgressTransport::execute that returns a response containing a
Retry-After header and verifies the resulting
RestrictedEgressResponse.retry_after contains the capped duration. Keep the
existing retry_after_hint unit test, but ensure the new test exercises the
header transfer through execute rather than calling retry_after_hint directly.

In `@crates/extensions/ironclaw_extension_host/src/channel_host/e2e_tests.rs`:
- Around line 484-521: Replace the duplicated bounded polling in
wait_for_slack_stream_starts, wait_for_slack_stream_stops,
wait_for_streamed_text_containing, and the inline stream-state loop with one
shared timeout-based helper that accepts a Harness predicate and diagnostic
label. Reuse the file’s existing tokio::time::timeout deadline and polling
interval, while preserving each wait_for_* helper’s existing failure diagnostic.

In `@crates/extensions/packages/slack/AGENTS.md`:
- Around line 52-55: Update the no-fallback rule in the Slack guidance to apply
only when the workspace app lacks Agent capability (`feature_disabled` or
`not_agent_app`); preserve the conventional terminal recovery path implemented
by `post_terminal_conventionally`, including its use of `post_slack_chunk` when
no stream was opened.

In `@crates/extensions/packages/slack/src/attachment_transfer.rs`:
- Line 505: Update the Url::parse error handling in the upload_ticket_request
flow to retain or log the underlying parse error while preserving the existing
sanitized Permanent message. Replace the discarded error binding in map_err
without changing the caller-facing sanitized reason.

In `@crates/extensions/packages/slack/src/payload.rs`:
- Line 338: Update the event handling around thread_ts and
ExternalConversationRef::conversation_fingerprint so non-DM stop events without
thread_ts return SlackInboundEvent::Ignore with
SlackIgnoreReason::MissingField("thread_ts"). Preserve the existing topic-less
behavior for DM events, and add a caller-level regression test covering the
non-DM missing-thread case.

In `@crates/extensions/packages/slack/src/reply_sink/agent_api.rs`:
- Around line 132-138: Preserve the distinction between unavailable and empty
Slack text in the read-back mapping: have the message text extraction in the
reply-sink method return None when text is absent or non-string instead of using
unwrap_or_default. Update resolve_pending to route this None result through the
read-back-unavailable path, retaining the pending state and Ambiguous outcome
rather than retrying the append; keep genuinely empty string text handled as a
verified comparison.

In `@crates/extensions/packages/slack/src/reply_sink/plan.rs`:
- Around line 91-100: The plan_chunks and resolve_pending flow must track answer
appends independently from attention blocks. Preserve separate per-append
evidence so answer-tail checks cannot span an emitted attention block, and use
that evidence when resolving pending appends; add a caller-level regression test
covering an answer append interleaved with attention and a later lost append.

In `@crates/extensions/packages/telegram/src/reply.rs`:
- Around line 76-87: Update the Telegram reply checkpoint handling around the
version validation and serde_json deserialization so unknown or malformed
checkpoints fail closed instead of returning None and triggering a repost.
Propagate an explicit ReplySinkOutcome::Ambiguous or Permanent outcome from the
surrounding reply flow, preserving valid checkpoint decoding and requiring
operator resolution for invalid durable publication evidence.

In `@crates/product/ironclaw_assistant/src/delivery_coordinator/publication.rs`:
- Around line 590-597: Ensure every early-return failure path in the session
registration flow releases the single-flight guard inserted into
session_registrations, including the snapshot.actor None branch and invalid
ReplyTargetBindingRef handling; use the existing release mechanism before
returning, or make the guard Drop-based and disarm it only after registration
succeeds.

In `@crates/product/ironclaw_assistant/src/projection/live_progress.rs`:
- Around line 654-665: Replace the array-based lookup in
runtime_kind_from_display with an exhaustive match over RuntimeKind variants,
mapping each variant’s as_str() value to its corresponding RuntimeKind. Keep the
existing Option<RuntimeKind> behavior for unmatched display text, and ensure
future variants require an explicit compiler-checked mapping.
- Around line 629-636: Update the work-summary publication in the live
projection flow to derive work_summary_id from the checkpointed
status_publications counter rather than the process-global sequence. Keep
next_live_sequence() for publication ordering, and preserve the existing counter
increment so republishing the same status reuses a stable id.

In `@crates/product/ironclaw_assistant/src/run_delivery/observer.rs`:
- Around line 726-731: Release the delivery permit in observe_ack before calling
await_reply_settled, after deliver_final_reply and any required publication work
complete. Keep the settlement wait for ordering purposes, but ensure it no
longer holds the permit so max_concurrent_deliveries bounds only active delivery
work.
- Around line 1034-1041: Update reply_delivered to require each publication’s
persisted target identity to match this observer’s target before accepting the
Delivered settlement; retain the existing run_id filtering and return false for
deliveries belonging to other targets. Add a caller-level regression test
covering one delivered matching target and one undelivered target.

In `@docs/internal/reborn/extension-runtime/overview.md`:
- Around line 230-237: Update the stale documentation passages describing
ChannelReply: require a ReplySink for both message and stream channel.reply
declarations, describe stream delivery through the surfaces.reply session
projection sink rather than host transports, and state that workspace file
materialization occurs during terminal-revision reply publication with
reject_caller_supplied_files enforcing the boundary.

In `@tests/e2e/fake_slack_api.py`:
- Around line 229-236: Apply the agent_feature_disabled check to the
chat.appendStream and chat.stopStream handlers in the fake Slack API, before
normal stream-state processing, returning the same disabled-feature error used
by chat.startStream and the session methods. Keep existing stream validation
behavior unchanged when the flag is not set.

In `@tests/integration/extension_delivery.rs`:
- Around line 1469-1506: Move the stream-open evidence and streamed-reply
assertions out of the initial polling snapshot and run them only after the
existing stopStream settlement poll completes. Then re-read captured requests,
rebuild stream_opens and streamed from the settled wire data, and pass that
fresh data to assert_slack_thread_delivery_evidence so delayed appendStream or
stopStream requests and duplicate opens are covered.

…tion gap

- The reply-publication publisher-id fallback no longer carries a
  panic-style unreachable arm: an (impossible) rejected id now logs at
  error level and refuses the start fail-closed, satisfying the Reborn
  production panic baseline.
- The integration extension-lifecycle profile binds the real Slack and
  Telegram channel adapters, exactly as the shipping binary does: the
  branch's activation rule fails closed on a declared [channel.reply]
  with no bound reply sink (a stub could swallow a run's answer), and
  the lifecycle scenarios install those real manifests. The acme runtime
  profile had already received this fix; the plain lifecycle profile had
  not, which is what broke tool_call's
  current_tool_surface_overrides_stale_assistant_unavailable_claim in
  the selected integration lane.

Review triage pass pushed (c1bdc10496 → 65326117f2, ten commits). Every thread from CodeRabbit (five passes), IronLoop, @henrypark133's review and approach audit, and the multi-agent review was re-verified against head and answered in place; the PR body's new Review triage pass section lists what changed and what was deliberately left alone.

  • 64 threads resolved, each reply naming the commit that fixed it or the evidence it was already handled at head.
  • 10 threads left open, all with the reason in the thread: nine on henrypark133's review that are by design or deferred (the 1,500-line repo ceiling vs a 1,000 one, private ReplyDocument fields, the finalize-after-terminal contract that a test pins, the Postgres leg of the outbound contract suite, terminal-fact recovery semantics, the bounded answer fold, projection eviction, the browser-side stream assertion), plus one product decision for Ben: a DM Agent Stop binds topic-less like a top-level DM message, but a threaded DM follow-up binds with the thread as topic, so a Stop pressed during a follow-up run finds nothing — bind DM thread replies topic-less too, or have Stop try both bindings.

Local verification on the pushed head: cargo fmt, cargo clippy --all --benches --tests --examples --all-features -- -D warnings, and a default-feature cargo check --workspace clean; architecture tests, composition budget, docs boundary; ironclaw_assistant (1365), ironclaw_composition (957), ironclaw_extension_contracts, ironclaw_outbound, ironclaw_extension_host + Telegram (690), the Slack crate; WebUI lint + typecheck + vitest (1601); and the root integration suite (reborn_integration_extension_delivery, reborn_integration_delivery_user_journeys) on libSQL and PostgreSQL.

633-636: 🗄️ Data Integrity & Integration | 🟠 Major | 🏗️ Heavy lift

Reject attachment batches above the document bound.

finalize_answer silently drops every attachment after REPLY_MAX_ATTACHMENTS. The conformance driver then sends all files while the document lists only the first 16. A terminal reply with 17 files can publish an incomplete reply model and lose user attachments without an error.

  • crates/contracts/ironclaw_extension_contracts/src/reply.rs#L633-L636: reject an over-limit attachment list before mutating the document, or use a fallible bounded attachment type that preserves the cause.
  • crates/contracts/ironclaw_extension_contracts/src/test_support/conformance.rs#L434-L456: add a >16-file regression case and require rejection before a terminal request can contain files absent from document.attachments.

As per coding guidelines: “Never silently discard model output, audit events, transcripts, or user data.”

Comment thread crates/extensions/packages/slack/src/reply_sink/checkpoint.rs
A claim whose lease had already lapsed by the time the provider call would
start produced a zero timeout budget; tokio still polls the sink once under
a zero timeout, then the elapsed timeout read as an ambiguity that, with
no checkpoint, settled the publication Unknown although no provider call
had been made. The worker now skips the call on a zero remainder and
returns a retry naming the lease; the next pass re-claims, and a terminal
revision that keeps lapsing fails closed under the retry budget. Pinned
red-first by a_lapsed_lease_skips_the_provider_call_instead_of_reading_a_zero_budget_as_ambiguity.

The WebUI run-id helper no longer spells the reducer's text-branch anchor,
so the static source pin that splits on it reads the reducer again (the
optional-chaining form is the simpler helper anyway). The extension
surfaces skill lists the three channel trait homes.

120-126: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Do not discard a successful final_reply after a stop race.

This fence calls runIdOfFrame before dispatch. runIdOfFrame returns the run ID for final_reply. If cancellation loses the race, the authoritative final reply is dropped and the stopped message remains. liftLocalStop only runs for a later non-cancelled projection status.

Exempt final_reply from this fence, or call liftLocalStop before rendering it. Add a regression case that delivers final_reply after a local stop.

As per coding guidelines, “UI success must follow backend evidence.”

The local-stop fence dropped every typed frame scoped to a run the user
stopped, including its final_reply. When the cancel lost the race and the
finalized reply outran the projection status that lifts the stop, the
authoritative answer was discarded and the Stopped notice stayed. The
final reply is the backend's own evidence that the run completed, so it
now lifts the stop (retracting the notice) and renders. Red-first vitest
case delivers the final reply before any projection status; the fence
test keeps every other typed frame fenced.

…list

A model answering "19." was invisible: to CommonMark a line holding only
an ordered-list marker is a list with one empty item, and the renderer
produced <ol start="19"><li></li></ol> while the transcript held the
answer. The renderer now escapes a bare marker outside code fences, so
the sentence renders as text; real lists and fenced code are untouched.
Rendered-output regression test for the bare, trailing-line, and
trailing-space forms plus the list and fence controls.

The expanded activity card rendered a Result tab with the tool's bounded
output preview, up to 16 KiB of raw JSON. The card now offers Details,
Parameters, and Error only; the output stays on the durable record for
diagnostics and channel flows. The dead result renderer, its two helpers,
and its two locale strings are removed. Rendered-card test: a completed
tool with a preview offers no Result tab, a failed one still surfaces its
error.

… real tasks, text by paragraph

Live validation found two presentation defects on the native Agent
stream. The plan opened every stream with a hidden-title sentinel task so
a lone plan_update would render; Slack hides the title and keeps drawing
its bullet. And every text delta went out as its own markdown_text chunk,
which Slack renders as its own block, so token boundaries became
paragraph breaks.

The sentinel is gone. The plan_update lifecycle label rides only with
real task cards, a stream opens only once the document holds renderable
content (a whole paragraph, a task card, a driver status line, or an
attention block), and the session status alone carries the thinking
state of a tool-less run. The stream stays in chunks mode for its whole
life — Slack forbids mixing markdown_text with chunks and a stream keeps
its opening mode — so progress text is published by whole paragraph: a
delta goes out through its last blank line outside a code fence, a
paragraph past SLACK_TEXT_HOLD_MAX_CHARS flushes at its last sentence
end, and the terminal, a finalized canonical answer, or a new attention
block flushes everything still held, so what the run said precedes the
block. The published-prefix hash covers exactly what Slack shows, so
rewrite detection is unchanged.

Plan-level pins (empty document plans nothing; header with the first real
task; paragraph, fence, hold-bound, terminal, and finalized cases) and the
forty agent-API journeys re-derived on the new exact stream sequences,
including a new paragraph-streaming journey; the channel-host working-
state journey asserts the session status with no stream before content.
Design doc updated; old checkpoints carrying the sentinel entry stay
readable and never re-send it.

Live-validation fixes pushed (dd7ee14af4 → 2d8dcdc8b1, three commits; details under Live-validation fixes in the body). Each lands at the owning seam with a behavior-level test, nothing synthetic:

  • 0d39217093 — WebUI renders a standalone 19.: the Markdown renderer escapes a bare ordered-list marker outside code fences (a rendered-output test covers the bare, trailing-line, and trailing-space forms plus list and fence controls).
  • ee72752ca3 — the activity card shows Details / Parameters / Error only; the tool output stays on the durable record. Rendered-card test.
  • 2d8dcdc8b1 — Slack: the hidden-title sentinel task is deleted; the plan_update header rides only with real task cards; a stream opens only once there is renderable content (session status carries the thinking state alone); text is published by whole paragraph in chunks mode (last blank line outside a fence; a paragraph past 600 chars flushes at its last sentence end; terminal / finalized answer / new attention block flush everything). The 40 agent-API journeys were re-derived on the new exact stream sequences.

Two things only a live workspace can confirm, in priority order:

  1. Block rendering with paragraph chunks — a multi-paragraph answer should now show paragraph breaks only where the model put them. If Slack still separates chunks visibly, the remaining lever is coarser flushing, not a mode change (Slack refuses markdown_text on a chunks stream).
  2. Tool-less runs have no plan header now — the probe that decides whether to bring it back is chat.startStream with plan_update + markdown_text chunks and no task_update: if that renders a header without an empty container, the header can ride with the first paragraph (a one-line gate change in plan.rs). Until then, a text-only answer shows Slack's native thinking status and the streamed text, nothing else.

Defer liftLocalStop until stale-status checks pass.

The batch pre-scan can lift the stop fence for an older locally stopped run, then isStaleTerminalStatus discards that run’s terminal status. This removes the “Stopped” notice and allows later stale items through. Keep the finalized reply after RunStatus; that ordering is intentional.

…rather than slice a char

The bare-number renderer toggled its fence state on any fence-like line,
so a ~~~ line inside a ``` block closed the state early and a bare
number after it was escaped inside the code. It now tracks the opening
delimiter and width and closes only on the same character at that width
or wider with nothing after it, as CommonMark specifies. Regression
proven against the previous version.

The Slack plan's publish boundary is a line end or the position past a
whitespace char, both char boundaries; the slice now goes through a
checked get that holds the text if that ever stops being true, with a
multibyte paragraph pinned. The final-reply fixture in the chat-events
race test carries the wire's required generated_at and asserts it is the
rendered timestamp.

…, push-only shared caches, stable toolchain, warm in-place mutation gate) (nearai#8050)

* ci: stop cold-compiling every Reborn lane

Three reference runs (PR nearai#8006 at 4bcdc76, merge-queue runs
33642416400 and 33656141094) showed every Tests (Reborn) lane compiling
its full dependency closure from cold: 0 of 47 lanes restored a Rust
build cache, and the three heaviest crate buckets compiled the closure
twice in one job (446+452 s, 483+514 s, 381+381 s, identical unit sets).
Compilation was 65% of PR test-lane minutes and 56-62% of queue minutes.

Root cause of the double build and of the dead cache: the hermetic
wrapper minted a fresh CARGO_HOME per invocation. Cargo hashes each
registry crate's absolute source path into its fingerprint, so the second
wrapper invocation in a bucket (nextest show-config, then nextest run)
marked every dependency PathToSourceChanged, and a restored target/ could
never be fresh inside the boundary (queue 33642416424's runtimes group
restored 1451 MB and still compiled 1298 units).

- scripts/ci/run-hermetic-test-process.sh: one stable, suite-owned Cargo
  home per host (still only registry/git symlinks, never host config or
  credentials). The self-test now pins a stable CARGO_HOME across
  sequential and parallel invocations, no host Cargo state inside it, and
  that a second guarded build compiles nothing.
- rust-cache saves are push-to-main only (10 sites). A merge_group save
  lands on the entry's gh-readonly-queue ref, which no pull request and
  no later entry can restore, so those saves were write-only and their
  6-7 GB per entry evicted main's caches from the 10 GB limit. Wrapper-
  built lanes share one `reborn-hermetic` lineage (crate buckets, root,
  integration, QA, Rust Reborn E2E groups); direct-cargo lanes share
  `reborn-direct` (sandbox Docker saves, mutation gate restores).
  RUST_MIN_STACK / RUSTC_BOOTSTRAP move from job env to step env so the
  lanes hash to one key.
- Crate buckets and the integration lane build on the pinned stable
  toolchain for PR, queue and dispatch runs; `cargo check --workspace
  --all-targets` (and with --all-features) on 1.98.0 passes without the
  nightly crate attributes. The instrumented push coverage run keeps
  nightly unchanged.
- The merge-queue mutation gate restores the warm cache and runs
  cargo-mutants --in-place (new opt-in gate flag, self-tested; implies
  --jobs 1) instead of a cold closure build per invariant (14.9 min for
  one invariant, 38.8 min for all eleven).

No test, lane, partition, or selection rule is removed or narrowed.

* ci: keep the branch-coverage RUSTC_BOOTSTRAP envelope, step-scoped

check-reborn-branch-coverage-flags.py counts four exact
`RUSTC_BOOTSTRAP: \"1\"` lines across the coverage workflows; the two
in reborn-tests.yml now live on the crate-tests and integration run
steps, where the instrumented push run executes and where rust-cache
does not hash them into the shared `reborn-hermetic` key.

* ci: keep RUST_MIN_STACK job-level, one value across the hermetic lanes

tests/reborn_coverage_lane_stack_headroom.rs reads the job-level
RUST_MIN_STACK of every lane that runs the integration package under
llvm-cov and ignores step-level values on purpose, so the step-scoped
placement failed the root partition on the exhaustive dispatch run
(33670885071). The value is job-level again and 64 MiB everywhere the
hermetic wrapper runs (crate buckets and the integration batch up from
8 MiB), because rust-cache hashes job-level RUST* variables into its key
and a per-lane value would split the shared reborn-hermetic lineage; a
larger minimum is a per-thread virtual reservation, not committed
memory. RUSTC_BOOTSTRAP stays step-scoped: the wrapper drops it either
way and the branch-coverage checker only counts the line.

* ci: harden the stable hermetic Cargo home and single-source its cache

Review follow-ups on nearai#8050:

- Compare canonical paths in the host-Cargo-home guard, so a symlink or a
  `..` spelling of the host home is refused like the literal path, and
  refuse an ancestor of the host home (the scrub below would otherwise
  delete host files). Regression: three equivalent spellings must exit 2
  and leave the host home untouched.
- Scrub Cargo config and credential files from the stable Cargo home on
  every entry: the home now outlives an invocation, so state one guarded
  command left there must not reach the next. Regression: files planted
  by one invocation are absent in the next.
- Only the push run's root partitions and QA replay save the
  `reborn-hermetic` cache (same complete integration-test closure); the
  Rust Reborn E2E groups restore only, so a small group finishing first
  cannot pin a partial dependency set under the once-per-lockfile key.

* ci: pass no --jobs to cargo-mutants in place

cargo-mutants 27.1 rejects --jobs next to --in-place even with a value
of 1 (the merge-queue gate for nearai#8050 failed with "the argument
'--in-place' cannot be used with '--jobs <JOBS>'"). In-place runs now
pass no --jobs at all; the self-test stub enforces the real mutual
exclusion so the pair cannot be emitted again, and asserts --jobs is
absent in both in-place forms.

…s are narration (nearai#8051)

* fix(reply): the answer is the current model call's text; earlier calls are narration

Live QA on the merged progressive-reply publication showed Slack (and
Telegram) answering "Let me find the conversation first.\n\nYour latest
message to Firat was: hello.": the projection concatenated every model
call's streamed text into one answer, and the terminal fold kept it because
the transcript's final message was its suffix.

The reply reducer now applies the transcript's own rule progressively. The
answer is the text of the current model call. The moment the loop does
anything after a call other than end the run — a capability invocation, a
gate, another call — that call's text was narration: `reset_answer` moves
it into a new typed `narration` facet under its answer phase and the next
phase starts empty. Provider reasoning stays reasoning.

Surfaces:
- WebUI: one live text item per model call again (`text:{run}:{phase}`, the
  pre-nearai#8006 shape). A phase the loop went past is republished once under
  its id with `narration: true`, ahead of the capability card; the browser
  folds it into the run's collapsible activity, keeps the trailing phase as
  the streaming bubble, and keeps narration through the final reply. No
  retraction on the wire, no inference from message order.
- Slack: a one-line narration never had a paragraph boundary and now never
  reaches Slack; held text no longer flushes ahead of an attention block;
  a narration paragraph already streamed, or any rewrite under the stream,
  closes the stale stream, retracts its message with `chat.delete`, and
  opens the fresh one — one stream is ever left standing. Telegram posts
  the final call's text instead of the concatenation.
- OpenAI-compatible lane: tracks phases by item id and emits a paragraph
  separator between them; a narration republish adds nothing; a same-phase
  rewrite still fails safely (it returned an internal error on any
  non-extension update, which a phase reset would have tripped).

Wire: additive `serde(default)` `narration` on the product and live text
items; the projection checkpoint gains `answer_phase` and
`narration_published`.

* fix(reply): review follow-ups — narration is live-only, retraction tolerates a gone message

- Product contract refuses `finalized` together with `narration` on
  construction and on the wire (a finalized transcript row is never
  narration); regression test.
- Slack re-present tolerates `message_not_found` on the stale close (an
  applied-then-lost `chat.delete` leaves nothing to close), the terminal
  rewrite path reuses it, and the lost-retraction journey runs both fault
  shapes; the fake's `deleted()` uses the poison-tolerant lock.
- WebUI: a narration republish that arrives after the durable final reply
  (the live and durable rails are independent) still joins the run's
  activity; late unflagged phases stay ignored. Regression test.
- Reducer: boundary test for the narration facet (entry count and byte
  bound on a char boundary); the contract doc says the bound is a display
  bound and the transcript keeps every model call in full.

Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

* fix(reply): narration is a role, the ordinal is `call`, retraction covers every fault shape

Local eight-reviewer pass before pushing (26 raw → 16 findings; 13 fixed,
3 declined with reasons in the PR):

- WebUI: narration is its own message role like `thinking`, so every
  `assistant` predicate excludes it by construction; the flag, its helper,
  and five inline guards are gone. `NoteItem` takes a `kind` and carries
  literal test ids. The WebUI module spec (`CONTRACT.md`) now describes
  per-call ids, the narration role, convergence, and late republishes.
- Contract: the answer ordinal is `call` (`ReplyAnswer.call`,
  `ReplyNarration.call`), distinct from the document lifecycle `phase`,
  renamed before it ships persisted. Owning-crate test for `reset_answer`.
- OpenAI-compatible lane: `TextUpdate` is an enum (Call / Narration /
  Confirm) over one streamed buffer; a narration republish shorter than
  what streamed (the document's bounded copy) is a no-op, never the
  rewrite that ends the client's stream; the finalized transcript row and a
  late republish of a closed call are pinned.
- Slack: `retract_message` defers to `outcome_for_failure` (`chat.delete`
  is idempotent, so a lost answer is retryable); only a refusal Slack will
  never lift leaves the stale message, marked silent-ok and pinned by a
  journey; rate limits retry before the fresh stream opens. A pending
  append whose text the document no longer holds (the loop reset the
  answer) re-presents instead of read-back clearing it and appending the
  next call beneath narration that may be showing.

Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

* fix(slack): tolerate only Slack's own permanent refusal of a retraction

A permanent outcome also covers a host egress denial or a request that
could not be built — failures that never reached Slack. Only a permanent
`ok: false` from Slack (a workspace that forbids the delete) leaves the
stale message; everything else keeps its usual outcome, pinned by an
egress-denied journey (no fresh stream opens). The Responses lane gets the
multi-call regression (deltas, `output_text.done`, `response.completed`
with one separator) and the narration render test asserts the note's kind,
text, and settled state.
