fix(server): re-snoozing a woken thread to the same wake time hides it again

[JonasFocus]

Problem

When a failure or a finished turn wakes a snoozed thread, snoozing it again with the same preset (This evening, Tomorrow, Next week) does nothing and the thread stays in the inbox. Those presets resolve to the same wake time, and the snooze handler treats an unchanged wake time as a duplicate and keeps the old snoozedAt, so the newer failure or completion keeps the thread awake. Fixes #14298.

Change

Every snooze now stamps snoozedAt and updatedAt from now, in the V2 orchestrator and in the optimistic client update in client-runtime. Retried commands are still deduplicated by commandId before the handler runs, which is what the old same-time check was protecting against.

Scope and approval

Triaged bug, and this is the fix the triage recommended. It's a rebuild of #14299 by @vitalyiegorov on V2, since that PR changed decider.ts, which the V2 merge removed. Credit to them for the original fix.

Verification

The existing V2 runtime test asserted the old behaviour; it now re-snoozes to the same wake time after a second and checks snoozedAt moved forward. There's also a new client-runtime test for the optimistic update. Both fail without the change, and typecheck is clean for the server and client-runtime. I haven't clicked through it in a running client.

Approvability

Verdict: Approved at 052ccbb

Macroscope's review found this PR approvable — This is a focused bug fix that synchronizes server and optimistic client snooze timestamps so re-snoozing after an early wake is reflected consistently. It changes no schemas, defaults, infrastructure, or security-sensitive code and includes targeted regression tests.

📝 Walkthrough

Walkthrough

Repeated snooze commands now update snoozedAt on both the client and server, even when the requested wake time matches the existing one. The server also updates updatedAt. Tests verify the timestamp changes.

Changes

Repeated snooze behavior

Layer / File(s)	Summary
Restamp repeated snoozes packages/client-runtime/src/state/threadCommands.ts, packages/client-runtime/src/state/threadCommands.test.ts, apps/server/src/orchestration-v2/Orchestrator.ts, apps/server/src/orchestration-v2/runtimeLayer.test.ts	The client and server now restamp snooze timestamps when a snooze uses the existing wake time. Tests verify the updated timestamps and client command completion.

Change: Bug fix · Severity of issue fixed: Low

Suggested reviewers: juliusmarminge

Merge Risk: 🔵 Low · up to 0af08

The new test can fail on systems whose clock predates its fixed fixture, though the production snooze behavior is unaffected. Pinning the test clock would make verification reliable; the merge risk is bounded.

• observed — packages/client-runtime (library) was modified; 2 changed files map to changed impact.
• 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/Orchestrator.ts: thread.snooze no longer compares the existing and requested wake times to preserve timestamps for a matching snooze. It now always restamps snoozedAt and updatedAt with the current time; updating snoozedUntil and clearing the recovery snooze flag remain unchanged.
• observed — Modified behavior in apps/server/src/orchestration-v2/runtimeLayer.test.ts: The test comment now states that repeating a calendar preset should restamp snoozedAt; the test advances the clock by one second before issuing the repeated snooze.
• observed — Modified behavior in apps/server/src/orchestration-v2/runtimeLayer.test.ts: The test now expects snoozedAt to be one second later than its initial value and updatedAt to match it, replacing assertions that both timestamps remain unchanged.
• observed — Modified behavior in packages/client-runtime/src/state/threadCommands.test.ts: Adds a test that re-snoozing at the existing wake time advances snoozedAt; after the queued request receives sequence 2, the command completes successfully.
