merge: combine #12871 (Kimi + coalescing + web_search) with #12873 (render flag + replay cap)

Mocks @ai-sdk/react so renderHook(useCopilotStream) can capture the
onFinish callback directly and drive handleReconnect without real SSE.
Two cases, both on vi.useFakeTimers():

- a burst of onFinish({isDisconnect: true}) inside the 1500ms window
  coalesces onto the boundary — resumeStream is called once for the
  first cycle, then a second time only after the window + attempt-#2
  backoff elapse.
- a disconnect arriving after the window closes takes the normal
  backoff path (not the debounce branch).

Covers the wiring lines shouldDebounceReconnect can't reach on its own
(useRef(0), the remainingDelay !== null branch's timer setup, and the
Date.now() stamp on resume). Together with the helper unit tests this
brings the codecov/patch diff for platform-frontend from 0% to full
coverage on the debounce lines.

 **Prevention:** Add `sleep 3` between individual thread reply API calls. When posting >20 replies, increase to `sleep 5`.
 
-**Recovery from secondary rate limit (403):**
+### Detection
+
+The `gh` CLI surfaces the GraphQL limit on stderr with the exact string `GraphQL: API rate limit already exceeded for user ID <id>` and exits 1 — any `gh api graphql ...` **or** `gh pr view ...` call fails. Check current quota and reset time via the REST endpoint that reports GraphQL quota (this call is REST and still works whether GraphQL is rate-limited OR fully down):
+
+```bash
+gh api rate_limit --jq '.resources.graphql'   # { "limit": 5000, "used": 5000, "remaining": 0, "reset": 1729...}
+# Human-readable reset:
+gh api rate_limit --jq '.resources.graphql.reset' | xargs -I{} date -r {}
+```
+
+Retry when `remaining > 0`. If you need to proceed sooner, sleep 2–5 min and probe again — the limit is per user, not per machine, so other concurrent agents under the same token also consume it.
+
+### What keeps working
+
+When GraphQL is unavailable (rate-limited or outage):
+
+- **Keeps working (REST):** top-level reviews fetch, conversation comments fetch, all inline-comment replies, CI status (`gh pr checks`), and the `gh api rate_limit` probe.
+- **Degraded:** inline thread list — fall back to flat `/pulls/{N}/comments` REST, which drops thread grouping, `isResolved`, and Relay thread IDs. You still get comment bodies and the `databaseId` as `id`, enough to read and reply.
+- **Blocked:** `gh pr view`, the `resolveReviewThread` mutation, and any new `gh api graphql` queries — wait for the quota to reset.
+
+### Fall back to REST
+
+**PR metadata reads** — `gh pr view` uses GraphQL under the hood; use the REST pulls endpoint instead, which returns the full PR object:
+
+```bash
+gh api repos/Significant-Gravitas/AutoGPT/pulls/{N} --jq '.body'           # == --json body
+gh api repos/Significant-Gravitas/AutoGPT/pulls/{N} --jq '.base.ref'       # == --json baseRefName
+gh api repos/Significant-Gravitas/AutoGPT/pulls/{N} --jq '.mergeable'      # == --json mergeable
+```
+
+Note: REST `mergeable` returns `true|false|null`; GraphQL returns `MERGEABLE|CONFLICTING|UNKNOWN`. The `null` case maps to `UNKNOWN` — treat it the same (still computing; poll again).
+
+**Inline comments (flat list)** — no thread grouping or `isResolved`, but enough to read and reply:
+
+```bash
+gh api repos/Significant-Gravitas/AutoGPT/pulls/{N}/comments --paginate \
+  | jq '[.[] | {id, path, line, user: .user.login, body: .body[:200], in_reply_to_id}]'
+```
+
+Use this degraded mode to make progress on the fix → reply loop, then return to GraphQL for `resolveReviewThread` once the rate limit resets.
+
+**Replies** — already REST-native (`/pulls/{N}/comments/{ID}/replies`); no change needed, use the same command as the main flow.
+
+**`resolveReviewThread`** — **no REST equivalent**; GitHub does not expose a REST endpoint for thread resolution. Queue the thread IDs needing resolution, wait for the GraphQL limit to reset, then run the resolve mutations in a batch (with `sleep 3` between calls, per the secondary-limit guidance).
+

+```
+
+### 3e-native. Run the app natively (PREFERRED for iterative dev)
+
+Native mode runs infra (postgres, supabase, redis, rabbitmq, clamav) in docker but runs the backend and frontend directly on the host. This avoids the 3-8 minute `docker compose build` cycle on every backend change — code edits are picked up on process restart (seconds) instead of a full image rebuild.
+
+**When to prefer native mode (default for this skill):**
+- Iterative dev/debug loops where you're editing backend or frontend code between test runs
+- Any PR that touches Python/TS source but not Dockerfiles, compose config, or infra images
+- Fast repro of a failing scenario — restart `poetry run app` in a couple of seconds
+
+**When to prefer docker mode (3e fallback):**
+- Testing changes to `Dockerfile`, `docker-compose.yml`, or base images
+- Production-parity smoke tests (exact container env, networking, volumes)
+- CI-equivalent runs where you need the exact image that'll ship
+
+**Note on 3b (copilot auth):** no npm install anywhere. `poetry install` pulls in `claude_agent_sdk`, which ships its own Claude CLI binary — available on `PATH` whenever you run commands via `poetry run` (native) OR whenever the copilot_executor container is built from its Poetry lockfile (docker). The OAuth token extraction still applies (same `refresh_claude_token.sh` call).
+
+**Preamble:** before starting native, run the kill-stray + free-ports block from 3c's "Native mode also" subsection.
+
+**1. Start infra only (one-time per session):**
+
+```bash
+cd $PLATFORM_DIR && docker compose --profile local up deps --detach --remove-orphans --build
+```
+
+This brings up postgres/supabase/redis/rabbitmq/clamav and skips all app services.
+
+**2. Start the backend natively:**
+
+```bash
+cd $BACKEND_DIR && (poetry run app 2>&1 | tee .ign.application.logs) &
+```
+
+`poetry run app` spawns **all** app subprocesses — `rest_server`, `executor`, `copilot_executor`, `websocket`, `scheduler`, `notification_server`, `database_manager` — inside ONE parent process. No separate containers, no separate terminals. The `.ign.application.logs` prefix is already gitignored.
+
+**3. Wait for the backend on :8006 BEFORE starting the frontend.** This ordering matters — the frontend's `pnpm dev` startup invokes `generate-api-queries`, which fetches `/openapi.json` from the backend. If the backend isn't listening yet, `pnpm dev` fails immediately.
+
+```bash
+for i in $(seq 1 60); do
+  if [ "$(curl -s -o /dev/null -w '%{http_code}' http://localhost:8006/docs 2>/dev/null)" = "200" ]; then
+    echo "Backend ready"
+    break
+  fi
+  sleep 2
+done
+```
+
+**4. Start the frontend natively:**
+
+```bash
+cd $FRONTEND_DIR && (pnpm dev 2>&1 | tee .ign.frontend.logs) &
+```
+
+**5. Wait for the frontend on :3000:**
+
+```bash
+for i in $(seq 1 60); do
+  if [ "$(curl -s -o /dev/null -w '%{http_code}' http://localhost:3000 2>/dev/null)" = "200" ]; then
+    echo "Frontend ready"
+    break
+  fi
+  sleep 2

+### Problem: Claude CLI not found in copilot_executor container
+**Symptom:** Copilot logs say `claude: command not found` or similar when starting an SDK turn.

+**Fix:** Rebuild the image cleanly: `docker compose build --no-cache copilot_executor && docker compose up -d copilot_executor`. Do NOT `docker exec ... npm install -g @anthropic-ai/claude-code` — that is outdated guidance and will pollute the container with a second CLI that the SDK won't use.

+that the OpenAI Python SDK doesn't model:
+
+* ``reasoning`` (legacy string) — enabled by ``include_reasoning: true``.
+* ``reasoning_content`` — DeepSeek / some OpenRouter routes.
+* ``reasoning_details`` — structured list shipped with the unified
+  ``reasoning`` request param.
+
+This module keeps the wire-level concerns in one place:
+
+* :class:`OpenRouterDeltaExtension` validates the extension dict pulled off
+  ``ChoiceDelta.model_extra`` into typed pydantic models — no ``getattr`` +
+  ``isinstance`` duck-typing at the call site.
+* :class:`BaselineReasoningEmitter` owns the reasoning block lifecycle for
+  one streaming round and emits ``StreamReasoning*`` events so the caller
+  only has to plumb the events into its pending queue.
+* :func:`reasoning_extra_body` builds the ``extra_body`` fragment for the
+  OpenAI client call.  Returns ``None`` for routes without reasoning
+  support (see :func:`_is_reasoning_route`).

+"""Pending-message buffer for in-flight copilot turns.
+
+When a user sends a new message while a copilot turn is already executing,
+instead of blocking the frontend (or queueing a brand-new turn after the
+current one finishes), we want the new message to be *injected into the
+running turn* — appended between tool-call rounds so the model sees it
+before its next LLM call.
+
+This module provides the cross-process buffer that makes that possible:
+
+- **Producer** (chat API route): pushes a pending message to Redis and
+  publishes a notification on a pub/sub channel.
+- **Consumer** (executor running the turn): on each tool-call round,
+  drains the buffer and appends the pending messages to the conversation.
+
+The Redis list is the durable store; the pub/sub channel is a fast
+wake-up hint for long-idle consumers (not used by default, but available
+for future blocking-wait semantics).
+
+A hard cap of ``MAX_PENDING_MESSAGES`` per session prevents abuse.  The
+buffer is trimmed to the latest ``MAX_PENDING_MESSAGES`` on every push.

+"""Tests for transcript context coverage when switching between fast and SDK modes.
+
+When a user switches modes mid-session the transcript must bridge the gap so
+neither the baseline nor the SDK service loses context from turns produced by
+the other mode.
+
+Cross-mode transcript flow
+==========================
+
+Both ``baseline/service.py`` (fast mode) and ``sdk/service.py`` (extended_thinking
+mode) read and write the same CLI session store via
+``backend.copilot.transcript.upload_transcript`` /
+``download_transcript``.
+
+Fast → SDK switch
+-----------------
+On the first SDK turn after N baseline turns:
+  • ``use_resume=False``  — no CLI session exists from baseline mode.
+  • ``transcript_msg_count > 0`` — the baseline transcript is downloaded and
+    validated successfully.
+  • ``_build_query_message`` must inject the FULL prior session (not just a
+    "gap" since the transcript end) because the CLI has zero context without
+    ``--resume``.
+  • After our fix, ``session_id`` IS set, so the CLI writes a session file
+    on this turn → ``--resume`` works on T2+.
+
+SDK → Fast switch
+-----------------
+On the first baseline turn after N SDK turns:
+  • The baseline service downloads the SDK-written transcript.
+  • ``_load_prior_transcript`` loads and validates it normally — the JSONL
+    format is identical regardless of which mode wrote it.
+  • ``transcript_covers_prefix=True`` → baseline sends ONLY new messages in
+    its LLM payload (no double-counting of SDK history).
+
+Scenario table (SDK _build_query_message)
+==========================================
+
+| # | Scenario                       | use_resume | tmc | Expected query message          |
+|---|--------------------------------|------------|-----|---------------------------------|

+Reproduces the bug where:

+  2. SDK generates a text response
+  3. GeneratorExit at StreamStartStep yield (client disconnect)
+  4. _dispatch_response(StreamTextDelta) is never called
+  5. Session saved with last_role=tool instead of last_role=assistant
+
+The fix: before yielding any events, pre-create the assistant message in

+present in adapter_responses.  This test verifies the resulting accumulator
+state allows correct content accumulation by _dispatch_response.
