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

[vitalyiegorov]

Problem

Fixes #14298. A failure that lands while a thread is snoozed wakes it, because the failure is newer than snoozedAt. Snoozing it again with the same preset (Tomorrow, Next week) sends the same wake time. V2's thread.snooze treats that as a duplicate and keeps the original snoozedAt, so the failure still counts as new and the thread stays in the inbox. The server accepts every retry and nothing visible happens.

Change

thread.snooze in apps/server/src/orchestration-v2/Orchestrator.ts always stamps snoozedAt and updatedAt with the current time. The client's optimistic update in packages/client-runtime/src/state/threadCommands.ts does the same, so web and mobile don't flash the thread back before the server replies. Retries of a single command are already deduplicated by command receipts, so the same-wake-time branch only ever ignored a deliberate re-snooze.

Whether a failure should wake a snoozed thread at all (#6368) is a separate question that this doesn't touch.

Scope and approval

• Julius triaged [Bug]: A thread that woke from snooze cannot be snoozed again to the same wake time #14298 as a real bug with this exact cause: [Bug]: A thread that woke from snooze cannot be snoozed again to the same wake time #14298 (comment)
• This rebuilds the closed fix(server): re-snoozing a woken thread to the same wake time hides it again #14299 on V2, as asked when it was closed: fix(server): re-snoozing a woken thread to the same wake time hides it again #14299 (comment)

Verification

• The existing V2 test carries snooze state through the V2 shell projection asserted the old behaviour. It now advances the clock between the two snoozes and expects a newer snoozedAt. It fails on main (expected false to be true) and passes with the fix.
• vp test run apps/server/src/orchestration-v2/runtimeLayer.test.ts packages/client-runtime/src/state/threadCommands.test.ts packages/client-runtime/src/state/threadSnoozed.test.ts: 113 passed.
• Typecheck of apps/server and packages/client-runtime. Lint and format on the touched files.
• No UI code changes. The before screenshots from the original report are in fix(server): re-snoozing a woken thread to the same wake time hides it again #14299.

Approvability

Verdict: Approved at 93cefff

Macroscope's review found this PR approvable — This is a small, regression-tested fix that keeps server and optimistic client snooze state consistent when a thread is deliberately re-snoozed to the same wake time. Its runtime impact is confined to refreshing snooze metadata so the intended hidden state is restored.

📝 Walkthrough

Walkthrough

Repeated snooze commands with the same wake time now refresh snoozedAt in the server projection and client optimistic state. The server also refreshes updatedAt. The projection test checks that the second snooze advances snoozedAt.

Refresh timestamps on repeated snoozes apps/server/src/orchestration-v2/Orchestrator.ts, apps/server/src/orchestration-v2/runtimeLayer.test.ts, packages/client-runtime/src/state/threadCommands.ts	Server snooze handling now refreshes snoozedAt and updatedAt on every command. The client optimistic update always refreshes snoozedAt. The projection test verifies that a repeated snooze with the same wake time advances snoozedAt.

Systems and components

• observed — apps/server (service) was modified; 2 changed files map to changed impact.
• observed — packages/client-runtime (library) was modified; 1 changed file maps to changed impact.

Before / after behavior

• observed — Modified behavior in apps/server/src/orchestration-v2/Orchestrator.ts: thread.snooze no longer compares the old and new wake times to preserve timestamps; every snooze now refreshes snoozedAt and updatedAt.
• observed — Modified behavior in apps/server/src/orchestration-v2/runtimeLayer.test.ts: The test now documents re-snoozing at the same wake time and advances the test clock by one minute before issuing the repeated snooze.
• observed — Modified behavior in apps/server/src/orchestration-v2/runtimeLayer.test.ts: The test now asserts that the second snooze's snoozedAt is later than the first, replacing assertions that snoozedAt and updatedAt stayed unchanged.
• observed — Modified behavior in packages/client-runtime/src/state/threadCommands.ts: The snooze optimistic update now assigns now to snoozedAt unconditionally, replacing the logic that preserved the prior timestamp when the existing and requested snooze deadlines matched.
