A settled thread stays in the Settled shelf — or flashes into Active and then drops straight back — after an agent or t3 thread send starts a new turn.
dispatchMessage already emits thread.unsettled and clears settledOverride when any message lands. Merge/close auto-settle then puts the thread back, because pullRequestSettles only treated createdBy: "user" messages as a resume anchor (latestUserAuthoredMessageAt). A CLI/MCP send is stored as createdBy: "agent" and creationSource: "mcp", so it never moves that anchor. The sweep settles the thread as soon as the follow-up run completes, with settledAt equal to that run's completedAt.
Reproduction
Use a project whose thread has a linked pull request that is already merged (or close one). Auto-settle on merge is on (the default).
Wait until the thread is in Settled, or choose Settle thread yourself.
From another agent or a terminal, send a follow-up: t3 thread send <id> "please also fix …" (or MCP t3_thread_send). Do not un-settle first.
When the run finishes — including an immediate failure, such as a provider usage limit — look at the sidebar.
Actual: the thread is still in Settled, grayed out at the bottom left. It may have been briefly active while the run was in flight.
Expected: the new turn un-settles the thread and returns it to the top of the active list, and it stays there for that burst of work. After the work goes idle, the usual inactivity rule can settle it again. Automatic wakes (pull request watch, delegated completion) should still not count as resuming.
Change
Keep the existing auto-unsettle in dispatchMessage. Teach merge/close auto-settle to treat an intentional agent/CLI/MCP message as a resume, the same way a user-authored message already is.
ThreadSettlementService.ts (isResumingSettlementMessage and pullRequestSettles): add latestResumingMessageAt to the settlement candidate. It is the latest user-role message that isResumingSettlementMessage accepts: createdBy === "user", or createdBy === "agent" with a creationSource other than "server" or "provider" (so mcp / CLI via MCP counts; PR-watch and provider wakes do not). Use that timestamp, along with createdAt and latestUserAuthoredMessageAt, as the resume anchor. A follow-up after mergedAt / closedAt then blocks merge-settle.
ProjectionStore.ts (getSettlementCandidates): compute latest_resuming_message_at in the existing settlement SQL, next to latest_user_authored_message_at, and map it onto the candidate.
docs/user/thread-sidebar.md: your messages and intentional agent/CLI/MCP follow-ups count as resuming; automatic wakes still do not. Those follow-ups also un-settle a settled thread and return it to Active.
Optional helper, not a sidebar UI change: isThreadReopenedUnseen (next to isThreadWokeUnseen in packages/client-runtime/src/state/threadSettled.ts) is true when unsettledAt is newer than lastVisitedAt, so a later change can show a "Reopened" chip the same way it shows "Woke". This PR does not wire that badge into the sidebar, so there is no visual change and no screenshot.
Inactivity auto-settle (default seven days) still applies once the burst is stale, because dispatchMessage still clears settledOverride to null instead of leaving a durable "active" pin. MCP disable_auto_settle (#26110) remains a good explicit opt-out for long-running orchestrator work.
Scope and approval
This is a focused fix of an obvious resume-anchor bug in merge auto-settle. The product already un-settles a thread when a message arrives, and already treats a later user-authored message as a resume; agent/CLI sends were left out of that same anchor, so the thread fell straight back into Settled. The change extends the existing resume rule rather than adding a new workflow or default.
It implements request (1) from open issue #26097, which describes this exact gap: agent-authored MCP messages never move latestUserAuthoredMessageAt, so merge auto-settle re-applies after every later run. That issue is not yet maintainer-triaged; this PR is submitted under the very small, focused fix of an obvious bug exception. Refs #26110, which exposes disable_auto_settle over MCP as an opt-out but is not automatic un-settle on a new turn.
Re-ran the three touched test files after the pre-commit hook (fmt, lint, and knip) on this change:
./node_modules/.bin/vp test run \
apps/server/src/orchestration-v2/ProjectionSettlement.test.ts \
apps/server/src/orchestration-v2/ThreadSettlementService.test.ts \
packages/client-runtime/src/state/threadSnoozed.test.ts
Result: 3 test files passed, 80 tests passed (17.04s). Those tests check:
isResumingSettlementMessage accepts user messages and createdBy: "agent" + creationSource: "mcp", and rejects server/provider wakes.
resolveAutoSettlementAt still settles on merge after an automatic wake whose user-authored resume is older than the merge.
resolveAutoSettlementAt does not settle on merge after an intentional agent/CLI turn later than the merge (inactivity can still settle later).
SQL: getSettlementCandidates leaves latestResumingMessageAt on the last user message when the newer message is an agent/provider notification, and moves it when the newer message is an MCP agent send.
isThreadReopenedUnseen is true after an auto-unsettle until the user visits, and false once they have.
I could not check the desktop sidebar visually; this PR does not change sidebar rendering. I also did not run a live t3 thread send against a merged-PR thread in a production app.
This was originally hit on T3 Code desktop 0.1.6. Current main (8ee7183e, package 0.1.8) still had the resume-anchor gap.
Treat intentional MCP/CLI agent follow-ups as resume anchors so merge
auto-settle does not immediately drop a settled thread back into Settled
after a new turn. Automatic server/provider wakes still do not count.
No actionable comments were generated in the recent review.
Walkthrough
Settlement candidates now track the latest user or intentional agent message, and merge settlement checks that timestamp. Client runtime adds a helper that identifies reopened threads not yet visited.
Settlement candidates include the latest qualifying resuming-message timestamp. Tests check values for user and agent messages.
Apply resuming activity to settlement apps/server/src/orchestration-v2/ThreadSettlementService.ts, apps/server/src/orchestration-v2/ThreadSettlementService.test.ts, docs/user/thread-sidebar.md
User-authored messages and agent messages outside the server and provider sources count as resuming. Pull-request settlement checks this activity timestamp. Tests and documentation cover intentional follow-ups and automatic wakes.
The client runtime identifies unsettled threads whose valid reopen timestamp is later than the last visit, or when no valid visit timestamp exists. Tests cover these conditions.

Explanation
Issue #26097 requests either a post-merge activity anchor or an MCP auto-settle opt-out. This PR implements the activity-anchor option. ProjectionStore.getSettlementCandidates selects latestResumingMessageAt for user messages and intentional agent messages, while excluding server/provider agent wakes. pullRequestSettles uses that timestamp with createdAt and latestUserAuthoredMessageAt. Tests cover message classification, SQL timestamps, and merge behavior after intentional agent turns. The issue's alternative opt-out is not required when the first option is implemented.

The SQL predicate in ProjectionStore.ts governs settlement. No production code calls this helper. Only tests call it. The helper and the SQL can drift apart. For example, the SQL also requires role = 'user' and excludes idle-compaction messages. Add a comment that names the SQL as the source of truth. Alternatively, remove the helper and test the SQL directly.
