🫗 fix: Drain Quoted Excerpts Into Mid-Run Steering (#15175)
* 🧭 fix: Carry Quoted Excerpts Through Mid-Run Steering

"Add to chat" quote chips were dropped by every during-run steer path: the
steer POST had no quotes concept, so a composer-origin steer left the chip
staged (gluing onto the NEXT send) and a queued item steered into the live
run lost its quotes silently.

Quotes now ride the steer protocol end to end:
- POST + admission: `quotes` on the steer body, normalized like the chat
  route's (getReferencedQuotes caps), part of the idempotency fingerprint
  only when present so pre-existing receipts still replay.
- Injection: merged into the model-bound turn as Markdown blockquotes at
  both boundaries (text-only and media paths), mirroring prependQuotes.
- Persistence + replay: the STEER content part stores `quotes` separately
  from the typed text; stampSteerPartMedia re-merges them per turn (even
  with resendFiles off) via the SDK's transient media stamp, with the quote
  block folded into the token budget.
- UI: composer steers/interrupt-steers drain the chips (skill picks stay
  staged — they configure a NEW turn's run); SteerPart and the in-flight
  bubble render the same MessageQuotes reference blocks as user bubbles;
  queued/failed rows show a quote count; reconnect reseeds fall back to the
  server item's quotes when no local chip survives.
- buildMessages keeps its zero-await path to the parallel context kickoff
  via a synchronous stamp-target probe.

* 🧭 fix: Keep Quotes in the Client-Safe Steer Projection

toPendingSteer is the projection behind resume-state pendingSteers, abort
responses, and terminal leftover claims — dropping quotes there would lose
them on exactly the recovery paths the reconnect reseed's server fallback
relies on.

* 🧪 test: In-Flight Steer Bubble Renders Carried Quotes

* 🔁 fix: Re-Stage Quotes When a Pre-Quotes Replica Accepts the Steer

Codex flagged the rolling-deploy window: an old replica 202s a quoted steer
while dropping the excerpts, so the client cleared the chips for context the
model never received.

The 202 (fresh and receipt replay) now echoes quotesAccepted from the
DURABLE item; a missing echo on a quote-bearing composer-origin steer
re-stages the excerpts as composer chips — the pre-steer behavior, so they
ride the next send instead of vanishing — and strips them from the surviving
chip so a later terminal conversion cannot duplicate them. Queued-origin
steers keep quotes on the item, whose restore paths already return it
intact. The residual cross-version lost-ACK retry stays fail-closed as a
409 idempotency conflict (failed chip with retry controls).

* 🔁 fix: Close the Remaining Cross-Version Quote-Loss Windows

Codex round 2:
- Send now of a quoted queued item against a pre-quotes replica now
  re-stages the excerpts too (the row is consumed and the words inject
  bare, so the composer is their only remaining home); the strip clears the
  chip's captured origin copy so reclaims and terminal conversions cannot
  duplicate them.
- A quoted retry whose lost first ACK was accepted by a pre-quotes replica
  now REPLAYS that legacy receipt instead of 409ing: the stored fingerprint
  matching the quote-less hash of the same words proves the cross-version
  case, and the replayed 202's missing echo drives the re-stage. Different
  quotes against a quote-bearing receipt still conflict.
- TSteerAppliedEvent.part gains the quotes field (typed SSE consumers).

* 🧪 test: Drop the Stale Narrow SteerDrainOutput Alias

The spec's local intersection re-declared injectedMessages with
content: string, predating the SDK pin that declares the field natively
(content: string | MessageContentComplex[]). Under CI's clean install the
hook's BaseHookOutput is no longer assignable to that narrower alias; the
plain PostToolBatchHookOutput is the correct type for every drain/boundary
assertion. Verified against the published 3.6.16 dist and the local one.

* 🔁 fix: Honor the Generation Owner's Quote Capability End to End

Codex round 4:
- steerQuotesCapable rides job metadata (createJob + HITL resume rewrite),
  mirroring preemptCapable's owner-recorded pattern: an upgraded admission
  replica no longer stores quotes — or claims them accepted — for a
  generation whose older owning drain would silently drop them at
  injection. The missing echo drives the client re-stage, and a later
  capable handover cannot double-deliver restored context.
- Applied events reconcile dropped quotes: when a quote-less applied part
  settles a quote-bearing chip (the lost-202 ordering the ACK-echo path
  cannot see), resolveSteerChip and both reconnect settle paths re-stage
  the chip's excerpts before removing their only copy. mergeRestagedQuotes
  dedupe keeps every trigger idempotent for the same excerpts.

* 🔁 fix: Re-Read Quote Capability at the Last Moment and Cap Restaged Chips

Codex round 5:
- A HITL resume rewrites steerQuotesCapable without changing the
  generation's createdAt, so the enqueue fence cannot see a
  capable-to-legacy handover landing during admission's awaits. Re-read
  the owner's flag immediately before item construction (paid for only by
  quote-bearing requests); the residual between re-read and enqueue commit
  matches preemptCapable's documented race.
- mergeRestagedQuotes now respects the 10-quote contract with the staged
  chips winning: a restored tail that cannot ride the next send is dropped
  explicitly instead of rendering as a chip the submission would silently
  discard. MAX_QUOTE_COUNT moves to utils/steer as the single client
  source; QuoteButton imports it.

* 🔁 fix: Steer Quote Coverage for Preflights, Memory, and Single-Scan Stamping

Codex round 6:
- Stored-message policy inspection now extracts steer-part quotes as quote
  fragments (path /content/N/quotes/M), so conversation import and shared
  link preflights inspect the newly persisted field exactly like top-level
  message.quotes.
- The memory copy gets its own quote-merge stamp (text only, resendFiles
  false): formatAgentMessages ignores part.quotes, so without it a steer
  whose substance lives in its excerpt reached the chat model but never
  memory extraction.
- collectSteerStampTargets replaces the boolean probe: buildMessages
  collects once and hands the targets to stampSteerPartMedia, keeping the
  zero-await fast path without scanning the history twice.

* 🔁 fix: Redis Quote Plumbing, Conversion-Race Guard, and Quote-Bound Recovery Proof

Codex round 7:
- RedisJobStore.deserializeJob now restores steerQuotesCapable (the explicit
  mapper otherwise dropped it on every read, leaving quote steering inert in
  Redis deployments), with the round-trip spec extended.
- Both Lua parked-steer projections (terminal close + generation
  replacement) forward item.quotes, matching toPendingSteer — a lost final
  no longer strips excerpts from durable recovery in Redis mode.
- The no-echo restage reads the SURVIVING chip (reclaimRejectedChipQuotes):
  a terminal conversion that beat the delayed 202 already moved the quotes
  onto the queued follow-up, and re-staging them again double-delivered.
  Regression-tested with the conversion-before-ACK ordering.
- RecoveredSteerPayload binds normalized, order-significant quotes (builder,
  validator, TS matcher, and the Lua decode+matcher): a stale client
  presenting the same recoverySteerId with altered or missing quotes cannot
  consume the parked source. Quote-less sources keep matching quote-less
  recoveries.

* 🔁 fix: Execution-Bound Quote Capability with an Atomic Enqueue Predicate

Codex round 8:
- steerQuotesCapable becomes a transient assertion translated (at createJob
  and in ApprovalLifecycle.resolve) into steerQuotesExecutionId, valid only
  while it equals the LIVE providerExecutionId. A legacy replica winning a
  HITL resume rewrites the execution id without knowing the marker, so its
  stale assertion self-invalidates — a bare boolean could not be cleared by
  code that predates it.
- The fenced enqueue evaluates that equality atomically (all three Redis
  scripts decode-and-strip like the existing preemptCapable normalization;
  both InMemory sites mirror it) and returns the persisted item, so the
  quotesAccepted echo reflects exactly what was stored even when a handover
  lands between admission's read and the commit. The last-moment re-read is
  gone — the transaction is the authority.
- Tests: capable-resume re-binding, legacy-resume omit-not-clear
  invalidation, the admission-vs-handover race (capability read true, then
  execution rewritten before enqueue), and the Redis round-trip of the
  marker.

* 🔁 fix: Full Redis Parking Coverage and Loss-Moment Quote Restaging

Codex round 9:
- The two remaining Redis parking projections (terminal status CAS and
  stale-running cleanup) forward item.quotes — every field-picked steer
  projection now carries them (audited: 2 Lua 'projected' + 2 Lua
  'clientItem' + toPendingSteer).
- The ordinary no-echo ACK no longer re-stages: the steer has not injected
  yet, so the quotes stay carried on the pending chip. A quote-less applied
  event re-stages them at the actual loss; a terminal leftover conversion
  carries them onto the recovered row, whose normal send delivers quotes on
  any server — re-staging at the ACK let that leftover auto-send bare text
  while the excerpts glued onto an unrelated draft. Only the settled
  receipt replay (already injected, no future event) reclaims immediately.

* 🔁 fix: Legacy-Replayable Receipts with Separate Quote Identity

Codex round 10: an upgraded-first receipt stored a quote-inclusive
fingerprint no pre-quotes replica could recompute, so a lost-ACK retry
routed through one 409'd already-accepted words with duplicate-send
controls.

The durable fingerprint reverts to the quote-independent 3-field hash —
the one shape EVERY deployed version computes, replayable across a rolling
deploy in both directions — and quote identity moves beside it as
requestedQuotesFingerprint (of the REQUESTED quotes, pre any capability
strip, so an incapable-owner acceptance still replays its own retries).
Absent records (legacy-written or quote-less) accept any same-words retry,
preserving the round-5 rule; present records must match exactly, keeping
different-quotes clientSteerId reuse a 409 on quote-aware readers. Under
the keep-on-chip client contract a legacy replay's missing echo is
harmless — the excerpts stay carried on the pending chip.

🚀 What's New in v0.8.8-rc1

  • Agent run control: Interrupt or steer an Agent mid-run, queue follow-up messages, and reclaim, edit, or escalate pending steers.
  • Human-in-the-loop Agents: Agents stream question progress, ask up to four related questions in one form, pause for input or tool approval, and resume.
  • Unified Agent Builder: A redesigned Tools marketplace brings together Skills, MCP, Code Interpreter, orchestration, Programmatic Tool Calling, model-spec controls, and per-tool background and intent settings.
  • Readable Agent activity: Generated activity-group headers, parent phase summaries, and live tool intent labels make long reasoning and tool runs easier to scan.
  • Code Interpreter workflows: Code and shell tools can run in the background, sandbox images return as viewable artifacts, and highly experimental stateful sessions can reuse prewarmed conversation workspaces.
  • Agent extensibility: Experimental Agent Plugins can bundle deployment Skills, MCP servers, and opt-in command hooks, while explicit subagents initialize only when selected.
  • Memory, context, and identity: Agents can manage memory with optional per-agent isolation, expose support contacts safely, and show a more faithful Context Usage gauge.
  • Sharing and files: Shared conversations show a badge and update at a stable URL, while signed-in viewers can continue them as personal copies.
  • Artifact workflows: Open previews fullscreen, work with PowerPoint .potx templates across upload, search, and code execution, upload shell scripts across common MIME variants, export Mermaid diagrams as SVG or PNG, and download original Office files from the artifact panel.
  • Models and reasoning: Added GPT-5.6 with Responses API reasoning controls, Claude Opus 5 and Sonnet 5, Gemini 3.7 and 3.6 Flash, and Gemini 3.5 Flash-Lite.
  • Langfuse observability: Configure encrypted Langfuse connections in-app, let authorized admins open sampled sessions directly, optionally fan out traces by tenant, and suppress central export per run.
  • Administration and security: Delegate config sections, encrypt registered secrets, enforce SSRF checks for speech, OCR, and web tools, and generate unique temporary credentials when secrets are blank.
  • Messages and navigation: Right-aligned user turns, unified multi-part editing, full-message copy, a dock-style message rail, virtualized search, smooth streaming, and faster Agent startup.
  • Streaming and tool reliability: Adaptive provider smoothing, Redis delta batching, dynamic MCP tool refresh, parsed MCP response media types, runtime OAuth recovery, and Agent stream circuit breakers improve long-running workflows.
  • Deployment and reliability: Added configurable HTTP timeouts, Amazon DocumentDB 5.0+ support, low-noise Redis and browser observability, and a rolling-upgrade-safe generation protocol.
