fix(server): woken snoozed threads get a fresh auto-settle window

[Mnigos]

Fixes #11788.

Problem

A snoozed thread that wakes on its timer is auto-settled on the next sweep, about a minute later, when its last activity is older than the inactivity window (3 days by default). A timed wake fires no event and updates no activity timestamp, so resolveAutoSettlementAt still measures inactivity from the work done before the snooze. The thread leaves Snoozed, shows up as woken for a moment and lands in Settled: a "Next week" snooze always does this, and so does any thread that was already idle for three days when it was snoozed.

Change

In the inactivity path of resolveAutoSettlementAt (apps/server/src/orchestration-v2/ThreadSettlementService.ts), a snooze that has already passed anchors the window: inactivity is measured from the later of the last activity and snoozedUntil. A woken thread therefore gets a full window from its wake time, and settles at the wake time if nobody touches it for that long. A thread that woke early, because a run completed or failed during the snooze, keeps its activity as the anchor: that wake is already in the activity timestamps, so the scheduled deadline passing later does not restart the window.

Unchanged: a snooze still in the future never anchors (the existing candidate gate and the early wake on a completed or failed run behave as before), a thread that was never snoozed settles from its last activity, and the merged or closed pull request path does not look at the snooze.

Scope and approval

Triaged bug #11788, following the fix named in the triage comment: "treat wake (snoozedUntil / early-wake time) as the inactivity anchor". This is the same approach as #12525, which was closed on 2026-09-19 while the orchestration layer was frozen for V2; this PR is written against the V2 ThreadSettlementService and verified there. Server only: one function plus tests. No contract, client or settings change, so web, desktop and mobile get the fix from the server.

Verification

Real web client on V2, before and after. Headless Chromium 153 at 1400×900 against vp run dev, main at e9298af versus this branch, each with its own isolated state and a stand-in provider (no real account or model call). One thread was created and snoozed through the UI; the servers were then stopped and the same timestamps were written into both databases: last activity 10 days ago, snooze ending 100 seconds after restart. Default settings (3 day window). No clock mocking, forced sweep or changed timer interval.

	Before (main)	After
62 s before wake	Snoozed shelf	Snoozed shelf
2 s after wake	Active list, "Woke" badge	Active list, "Woke" badge
110 s after wake	Gone from the list, Settled (1)	Active list, "Woke" badge, Settled (0)
Database	thread.settled by server 27.5 s after wake, settledAt = the 10 day old activity	No settlement event

Before (main): 110 s after wake the thread is settled	After: the thread is still in the list

The recordings are real time (about 170 s each, sidebar only). The "Update Available" toast in the screenshots is unrelated.

Tests. ThreadSettlementService.test.ts gains 16 cases (35 pass): snooze ended an hour ago stays active; snooze ended 4 days ago settles at the wake time; activity after the wake wins; a future snooze does not anchor, including the early wake on run completion; never snoozed; inactivity settlement disabled; merged and closed pull requests keep settling from activity; and a worker sweep that settles a never-snoozed thread while leaving an identical recently woken one, waiting on the queue receipt and worker drain. Six more cover the early wake: early completion and early failure with a passed deadline, a failed thread with an unknown snooze start, a timed wake whose completion predates the snooze, and one thread evaluated a minute before and after its deadline. With the function reverted, 3 of the first group fail; with the early-wake check removed, 4 of the second. Server typecheck, targeted lint, format and knip are clean.

Not checked: the full three day window in a live server (the capture covers two sweeps after the wake; the settle-at-wake-time case is covered by the test), desktop and mobile clients (no client change), and a thread unsnoozed by hand, which clears snoozedUntil and is outside this fix.

Implemented with Claude Code (Claude Opus 5.5, coordinated by Claude Fable 5.1); tests, independent review and evidence capture by GPT-6 Astra via Codex.

📝 Walkthrough

Walkthrough

The auto-settlement service now accounts for expired snoozes when it calculates inactivity. Early completion or failure can affect the settlement anchor. Tests cover anchor conditions and worker dispatch.

Snooze-aware auto-settlement

Layer / File(s)	Summary
Settlement anchor and worker validation apps/server/src/orchestration-v2/ThreadSettlementService.ts, apps/server/src/orchestration-v2/ThreadSettlementService.test.ts	The service uses the later of the wake time and latest activity for an expired snooze, unless the thread woke early. Tests cover active and future snoozes, disabled inactivity settlement, early completion or failure, merged or closed pull requests, and worker dispatch.

• observed — apps/server (service) was modified; 2 changed files map to changed impact.

Before / after behavior

• observed — Modified behavior in apps/server/src/orchestration-v2/ThreadSettlementService.test.ts: Added resolveAutoSettlementAt tests for snooze wake-time anchoring, recent activity after wake, future snoozes, disabled inactivity settlement, completion-based wake-up, and merged or closed pull requests.
• observed — Modified behavior in apps/server/src/orchestration-v2/ThreadSettlementService.test.ts: Added a worker sweep test asserting that an expired snooze prevents auto-settlement based on old activity, while a never-snoozed thread with the same old activity is dispatched for settlement.
• observed — Modified behavior in apps/server/src/orchestration-v2/ThreadSettlementService.ts: When a snooze has expired, resolveAutoSettlementAt uses the later of its wake time and the latest activity as the inactivity anchor; otherwise it uses the latest activity. The day threshold and returned settlement timestamp now use that anchor instead of always using the activity timestamp.

Explanation

Issue [#11788] has two coding objectives. The PR satisfies the wake grace-period objective: resolveAutoSettlementAt uses the later of activity and expired snoozedUntil, and tests cover timed wakes, early completion or failure, future snoozes, disabled inactivity settlement, and pull-request cases. The PR does not implement or test persistence of a disabled auto-settle setting. The reviewed change is server settlement logic only, and the summary states that no settings change was made.

[JonasFocus]

Anchoring the window on an expired snoozedUntil while early completion and failure keep their own activity is the right shape, and the before and after capture makes it easy to trust.

On the hand-unsnoozed case you listed under not checked: it's worth a follow-up issue rather than just a note, because it's the same symptom as #11788 and arguably a worse one. "Wake now" and "Wake thread" send thread.unsnooze, which nulls both snoozedUntil and snoozedAt (Orchestrator.ts around line 2550), so resolveAutoSettlementAt only sees the old activity. A thread that sat idle for three days before the snooze gets settled on the very next sweep, about a minute after the user explicitly asked for it back. Fixing it means unsnooze has to leave a wake stamp behind, which also touches the client's Woke indicator in threadSettled.ts, so I agree it doesn't belong here, but it would be easy to lose once this closes #11788.

For what it's worth, this doesn't conflict with #14887 (re-snoozing to the same time restamps snoozedAt); the two compose, and with both in, a same-time re-snooze after an early wake gets your anchor at the new deadline.

Note

🤖 Claude Fable 5.1 on behalf of Mnigos

Confirmed in the code: thread.unsnooze sets both snoozedUntil and snoozedAt to null (Orchestrator.ts, the "thread.unsnooze" case), and resolveAutoSettlementAt only anchors on a snoozedUntil that is still set and already passed. So a thread woken by hand has nothing left to anchor on, and one whose last activity is older than the window is a settlement candidate on the next sweep. Pinning a snoozed thread clears the same two fields, but a pinned thread is excluded from auto-settle.

This PR leaves that case as it is on main: fixing it needs unsnooze to record when the wake happened, which is a change to the command's result and to how the client derives "Woke", not to the settlement resolver. It is listed under "Not checked" for that reason, and no follow-up issue has been filed for it yet.

Agreed on #14887: it restamps snoozedAt on a same-time re-snooze, and the early-wake check here compares the last completion against snoozedAt, so after that re-snooze the thread counts as snoozed again and the passed deadline anchors as intended.
