Active task: Escalation Mode wedge build. Full status in CURRENT_TASK.md; this file is the resume point.

Branch: feat/escalation-metric-endpoint. Local tip is 665530f. Remote (origin) is at 8914391 — the last two commits (0f00ee5, 665530f) are local-only because the user is swapping computers and asked for the docs/handoff first. Push needed on next session before continuing work. Draft PR #155 is open against main.

What this session did

Two commits, both untested in a real browser:

1. 0f00ee5 feat(escalations): close out plan-locked wedge polish. Four items from the design-plan audit (docs/plans/2026-04-27-escalation-mode-wedge-design.md):

   • Live AI assessment refresh — frontend listener for the handoff_assessment_ready SSE event, refetches the handoff and updates magicHandoff / overlayHandoff in place. Closes the async-assessment loop from e8ba74e.
   • Suggested-step chips below the composer in AssistantChatPage — surfaces ai_assessment_data.suggested_steps[] post-claim, click prefills the input, hides on first send or explicit X.
   • Unread 6px dot on EscalationQueue cards — localStorage-persisted seen set (rf-escalation-seen), clears on open OR claim (NOT hover; Codex correction).
   • Race-condition toast on claim conflict — new HandoffAlreadyClaimedError exception, endpoint returns 409 with structured {claimed_by_id, claimed_by_name, claimed_at}, frontend shows "Already claimed by {name} {time_ago}." and bounces the loser back to the queue. Backed by 2 new tests; full handoff/escalation suite (34 tests) green.

2. 665530f fix(assistant-chat): tag task-lane state with owner chatId. Structural fix for the recurring "new session shows previous session's task lane" bug. The earlier fix 8914391 only covered the mount-time entry path; this change makes stale data structurally unable to display by adding taskLaneOwnerChatId state and a render gate taskLaneOwnerChatId === activeChatId ANDed into all three render conditions. Persistence effect now writes ownership chatId, not active chatId — that was the original write-side bug. See DECISIONS.md for the architecture write-up.

Verified: tsc -b clean after both. Backend handoff/escalation suite (34 tests) green. Not verified: anything in a real browser. The user explicitly asked for a debugging session after implementation — that's the next thing.

Resume point

1. First action: git push the two local commits. 0f00ee5 and 665530f are local-only.
2. Visual QA + bug bash. End-to-end demo flow:
   • Junior escalates → senior gets bell-icon notification → click → magic-moment screen with placeholder AI assessment (because it's now async/background) → assessment populates in place within ~5–15s without manual reopen → Start here → chat surface loads with suggested-step chips above the composer → click a chip prefills input.
   • On /escalations: backgrounded tab gets (N) title prefix when an arrival fires; new card has 6px accent dot top-right; clicking the card body OR Pick Up clears the dot (verify it persists across refresh, doesn't clear on hover).
   • Race condition: claim the same handoff from two browsers; loser sees toast "Already claimed by {name} {time_ago}." and bounces.
   • Task-lane regression check: create a new session via dashboard prefill / pickup / "New Chat" — the lane must NOT flash the previous session's questions/actions. The user previously reported this happening repeatedly; the fix in 665530f should kill it. If it still happens, that's the next debug target.
3. Deferred follow-ups in CURRENT_TASK.md: snapshot expansion, owner-facing /analytics/escalations page, Playwright e2e for the GTM Loom demo path, eventual cleanup of flowpilot_engine.escalate_session and the dead FlowPilotSessionPage.tsx magic-moment branch.

Useful breadcrumbs

• SSE endpoint: backend/app/api/endpoints/session_handoffs.py — stream_escalations.
• Pub/sub bus: backend/app/core/escalation_bus.py.
• Frontend SSE consumer: frontend/src/api/aiSessions.ts → streamEscalations (now dispatches handoff_created AND handoff_assessment_ready).
• Live-arrival queue UI: frontend/src/components/flowpilot/EscalationQueue.tsx.
• Magic-moment screen: frontend/src/components/flowpilot/HandoffContextScreen.tsx.
• Pickup integration + magic state machine + suggested-step chips + assessment-ready subscription + claim 409 handling + task-lane owner tagging: frontend/src/pages/AssistantChatPage.tsx.
• Claim conflict exception: backend/app/services/handoff_manager.py — HandoffAlreadyClaimedError, claim_session, enrich_escalation_async.
• Metric endpoint: backend/app/api/endpoints/flowpilot_analytics.py.

Watch-outs

• The two new commits are local-only until pushed. Run git push before any other work.
• The assessment-ready subscription opens a fresh SSE connection scoped by assessmentMissing && trackedHandoffId. If you change the magic-moment lifecycle, double-check the cleanup deps don't churn the subscription.
• The claim conflict path is currently only wired into AssistantChatPage.handleStartHere. useHandoff (used by SessionQueuePage) and FlowPilotSessionPage.tsx (dead) were not updated. If SessionQueuePage claims start mattering, mirror the same axios.isAxiosError(e) && e.response?.status === 409 extraction.
• The handoff snapshot is still sparse (problem_summary, problem_domain, status, step_count, confidence_tier). Magic-moment "What's been tried" still only shows engineer notes + step count pre-claim.
• HandoffResponse.ai_assessment_data.confidence is typed number on the frontend but the backend currently emits 'low' | 'medium' | 'high'. Runtime handles both; type definition is stale.
• Toolbar "Context" button is hidden on revisited active sessions where the senior didn't arrive via magic-moment this session — known scope cut.
• Do not reintroduce client.stream()/ASGITransport tests for infinite SSE responses; test the generator directly.
• Bus is acceptable for v1 pilot scale only (Railway single-replica). Redis pub/sub is the obvious swap when horizontal scaling appears.
