Active task: Ship PR #153 — the AssistantChatPage prefill currentChatRef bug fix. See CURRENT_TASK.md.

Branch: fix/tasklane-prefill-ref → PR #153.

Current resume point

PR #150 is merged. Branch fix/tasklane-prefill-ref has been rebased onto the new main (HEAD 1559feb) and force-pushed; that pulled in the workflow fixes from #150, so the prior backend port-conflict and frontend upload-artifact failures are gone structurally.

CI was kicked off automatically on the rebased SHA. Watch:

• CI / backend (pull_request) — should pass now that postgres uses the docker-network DNS name postgres:5432 (no host port race).
• CI / frontend (pull_request) — should pass now that the actions/upload-artifact@v4 step is removed.
• CI / e2e (pull_request) — runs on its own postgres + builds frontend inline. Includes the new e2e/assistant-chat-prefill.spec.ts regression test, which stubs /ai-sessions/*/chat with page.route and is independent of Anthropic.

If all three go green, merge #153 into main.

What this PR fixes

Reported symptom: in a troubleshooting (chat) session, after answering a subset of the task-lane questions and clicking Send N of M Responses, no AI response appeared.

Root cause: the dashboard prefill effect in AssistantChatPage set activeChatId after creating a new session but never updated currentChatRef.current. The currentChatRef.current !== sentForChatId guard inside handleSend and handleTaskSubmit then bailed silently on every later request and discarded the AI's reply.

Fix is a single line: assign currentChatRef.current = session.session_id immediately after setActiveChatId(session.session_id) in the prefill effect, mirroring handleNewChat and handleResumeNew.

Verification completed

• New regression test frontend/e2e/assistant-chat-prefill.spec.ts drives the real dashboard prefill flow against the real backend, stubs /ai-sessions/*/chat for deterministic turn-1/turn-2 responses, asserts the second AI message renders. Confirmed it fails on unfixed code at the exact assertion (Got it — based on your answer… never appears) and passes once the fix is restored.
• tsc -b clean. No new lint errors. Adjacent specs (flowpilot-chat) still pass.

Branch protection on main (current)

• PR-only merges
• CI / frontend (pull_request) required
• CI / backend (pull_request) required (added during PR #150 close-out)
• Force-push blocked
• No review required (solo)

Immediate next steps

1. Watch PR #153 CI on 1559feb.
2. Merge PR #153 when all three checks are green.
3. After merge, decide whether to promote CI / e2e (pull_request) to required (would make this two consecutive green PR e2e runs in a row, the threshold from the prior CURRENT_TASK).
4. Pick next item from .ai/TODO.md — top "Up next" is the data-testid audit; the currentChatRef silent-return follow-up is in Backlog and is a natural pairing with this fix.

Useful breadcrumbs

• Bug fix: frontend/src/pages/AssistantChatPage.tsx around line 258 — the currentChatRef.current = session.session_id line in the prefill sendPrefill effect.
• Regression test: frontend/e2e/assistant-chat-prefill.spec.ts.
• TODO entry tracking the broader silent-return audit: .ai/TODO.md.
