feat(web): choose the hours snooze presets wake at

[Silthus]

Problem

The calendar snooze presets wake at fixed hours: This evening at 18:00, Tomorrow and Next week at 9:00. If your day starts at 5:00 or ends at 21:00, you have to open Custom… every time.

Scope: this is a focused configuration option for an established capability. The three calendar presets already exist and already wake at fixed hours. The option only picks those hours. It adds no new presets or workflow, and the defaults stay 9:00 and 18:00.

Note

🔵 Merge risk: low (merge-risk rubric)

• Two new per-device client settings join the ClientSettings contract. Older settings files decode to 9:00 and 18:00, so nothing changes until someone picks an hour.
• The shared change is one defaulted parameter on resolveSnoozePresets, covered by focused tests on both seams. The diff reverts cleanly.

Total	12	+291 −23

• Settings → General → Snooze times holds a Morning and an Evening picker in one row. Morning sets Tomorrow and Next week (any hour), Evening sets This evening (noon to 23:00). Labels follow the Time format setting.
• Every web and desktop snooze menu uses both hours: the row snooze button, the row context menu, the bulk selection menu, and the thread action menu in the chat header.
• The row's reset arrow, Restore device defaults, and settings search cover the new row.
• The evening hour starts at noon. An earlier hour is a morning, and midnight is always past or under an hour away, so This evening would never show up.
• Mechanical: snoozeMorningHour and snoozeEveningHour join ClientSettingsSchema and ClientSettingsPatch. The shared resolveSnoozePresets takes { morningHour, eveningHour }, defaulting to 9 and 18. The web wrapper requires them, so a new web entry point can't silently fall back. Sidebar reads both once and passes them to rows as props, like timestampFormat.
• Mobile keeps 9:00 and 18:00. It has no client settings store today, and adding one is out of scope.
• docs/user/thread-sidebar.md gains one sentence on where to change the hours.

Before (main)	After (Morning 5:00 AM, Evening 9:00 PM)

Related: #15679 adds saved custom presets but keeps the built-in hours fixed. The two PRs touch the same function, so whichever lands second needs a small rebase.

How did you test this code?

Test rationale: The seams are resolveSnoozePresets (shared), its web wrapper, and useSettingsRestore. Each new test failed before its change.

• threadSnoozed.test.ts: with Morning 5, Tomorrow and Next week resolve to 05:00 on the right local days. With Evening 21, This evening resolves to 21:00 and drops out once less than an hour remains.
• Sidebar.snooze.test.ts: the menu time column reads 21:00, 05:00, and Mon 05:00.
• SettingsPanels.restore.test.tsx: changing either hour shows "Snooze times" in restore defaults, and restoring resets both.
• settings.test.ts: the settings patch accepts evening hours 12 to 23 and rejects 0, 1, and 11.

Scoped tsc --noEmit passes for contracts, client-runtime, web, and mobile. Lint shows no new findings in the touched files.

Checked in a running web client (vp run dev, headless Chromium): picking Morning 5:00 AM and Evening 9:00 PM updates every menu label above. Snoozing until This evening stores snoozedUntil at 21:00 today, and Tomorrow stores 05:00 the next day. The row's reset arrow brings both back to 9:00 AM and 6:00 PM.

Not checked: the desktop app shell, which reads the same client settings through its bridge.

Skills: tdd, writing-voice, qa-swarm, agent-browser, merge-risk.

Six QA rounds ran, each panel with six GPT-6.1 Sol lenses and two Claude Opus 5.5 lenses. The first version covered only the morning hour. Its rounds moved the settings read out of each sidebar row and made the web wrapper's hours required. The evening hour and the grouped "Snooze times" row came next. Their panel found a docs wording nit, and CodeRabbit found that an evening hour of 0:00 could never show This evening, which led to the noon bound. The last panel came back clean.

📝 Walkthrough

Walkthrough

The change adds configurable morning and evening snooze hours, with defaults of 9:00 and 18:00. Snooze presets and web settings use these values. Settings can restore both hours to their defaults.

Changes

Configurable snooze times

Layer / File(s)	Summary
Define snooze hours and resolve presets packages/contracts/src/settings.ts, packages/client-runtime/src/state/threadSettled.ts, packages/client-runtime/src/state/threadSnoozed.test.ts, packages/contracts/src/settings.test.ts	The settings contract accepts morning hours from 0 to 23 and evening hours from 12 to 23. It defaults them to 9 and 18. The shared resolver uses the configured hours for “This evening,” “Tomorrow,” and “Next week.” Tests cover accepted evening-hour values, custom preset times, and the evening preset boundary.
Edit and restore snooze hours apps/web/src/components/settings/SettingsPanels.tsx, apps/web/src/components/settings/settingsSearch.ts, apps/web/src/components/settings/SettingsPanels.restore.test.tsx	General settings adds searchable selectors for morning and evening hours. The selectors format the choices using the selected timestamp format. Restoring defaults resets both hours to 9 and 18.
Use configured hours in snooze menus apps/web/src/components/Sidebar.snooze.ts, apps/web/src/components/Sidebar.tsx, apps/web/src/hooks/useThreadActionMenu.ts, apps/web/src/components/Sidebar.snooze.test.ts, docs/user/thread-sidebar.md	Sidebar and thread action menus pass configured hours to preset resolution. Tests cover default and custom preset labels. Documentation lists the defaults and settings location.

Merge Risk: ⚪ Minimal · up to 5158a

Web and desktop users can configure the snooze wake times, and the shared presets use those settings. The available evidence shows no actionable merge-blocking risk; the change is ready for normal checks.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 5158a

The change adds bounded, device-local preferences while retaining existing snooze commands and controls. No introduced security weakness was identified. Remaining uncertainty concerns production lifecycle and downgrade behavior, rather than a demonstrated vulnerability.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The added control is limited to device-local preset-hour selection. Its downstream effect is a wake timestamp on threads targeted through existing snooze actions, including existing bulk selection. No additional target identity or privilege is introduced by the hour values.

Trust Boundaries and Controls

• inferred — User-controlled preference values remain constrained inputs to timestamp construction, not credentials or authority selectors. Existing custom snooze already accepted selected dates and times through the same command path. Configurable presets therefore do not establish increased scheduling authority or bypass of the inspected client controls.

Resilience and Maintainability Implications

• observed — Failed snooze initiation does not publish a successful undo notice; successful initiation retains ordinary unsnooze as its undo action. Malformed or elapsed wake timestamps do not classify a thread as hidden, and timer wake remains derived from the existing stored timestamp.
