Why

New threads still fall back to Full access unless something carries from the thread you're looking at. That matches neither what people asked for in #2662 nor how they actually work: most folks want the last mode they used in that project, and a machine fallback when there is no last-used yet.

#3086 tried to fix this with one global Default access setting that stamped every new thread. It got closed. Fair call on the blunt shape. This PR keeps a machine default, but puts it where the other new-thread defaults live, and prefers the project's last-used mode when one exists.

What changed

Precedence for a new thread's access mode:

  1. Whatever is already set on the unsent draft
  2. Same-project carry from the thread or draft you're viewing
  3. Last-used mode for that logical project (web + mobile)
  4. Machine defaultRuntimeMode from Settings
  5. Hardcoded Full access

UI: Settings → Projects → Project defaults → Default access, next to Model / Workspace. Same four options as the composer picker (Supervised, Auto-accept edits, Auto, Full access).

Also fixed a resurrect bug I hit while testing: we wrote the resolved mode onto the draft-thread session but not the composer draft the picker reads, so the UI could keep showing a stale mode.

And stopped writing the machine default into last-used storage on mint. That was shadowing later Default access changes, including Auto.

Testing

Ran this against an isolated local web stack on the branch:

  • Confirmed Default access shows under Project defaults and persists (wrote defaultRuntimeMode: approval-required to settings).
  • Changed the composer picker to Auto-accept edits and saw last-used land in localStorage for the logical project.
  • From Settings with no thread carry, opened a new thread while last-used was Auto-accept and the machine default was Supervised. Composer showed Auto-accept after fixing the resurrect sync bug.
  • Cleared last-used, left the machine default at Supervised, opened a new thread again. Composer showed Supervised without writing last-used from the machine default alone.
  • Confirmed Default access Auto applies to a new thread when last-used is empty.
  • Focused unit tests for the shared resolver, contracts setting, web/mobile last-used stores, and useHandleNewThread (including composer sync on resurrect).

Summary by CodeRabbit

  • New Features

    • Added project-specific “Default access” settings with selectable runtime modes, validation, reset, and searchable settings.
    • New threads now remember the last-used runtime mode for each project.
    • New-thread mode selection now prioritizes explicit choices, carried settings, project preferences, and configured defaults.
  • Bug Fixes

    • Improved consistency of runtime-mode selection across web and mobile.
    • Preserved existing runtime-mode preferences when restoring drafts and migrating saved settings.

Remember each project's last-used permission mode for new threads, and add a
machine-level Default access setting under Project defaults as the fallback.

Seeding sticky from the machine default on every new thread made later
Default access changes, including Auto, never apply. Only carry and
explicit picker changes write sticky now.

Use lastUsed naming for the per-project remembered access mode so it
does not collide with machine defaultRuntimeMode. Keep a read path for
the old persisted sticky keys.

📝 Walkthrough

Walkthrough

Runtime modes now resolve from draft, carried, last-used, and configured values. Web and mobile stores persist per-project selections. Project settings expose a configurable default access mode.

Changes

Runtime mode preferences

Layer / File(s) Summary
Runtime mode contract and resolution
packages/contracts/src/settings.ts, packages/shared/src/runtimeMode.ts, packages/shared/src/runtimeMode.test.ts
Adds defaultRuntimeMode to server settings and defines precedence for resolving new-thread runtime modes.
Per-project runtime-mode persistence
apps/web/src/composerDraftStore.ts, apps/web/src/composerDraftStore.test.ts, apps/mobile/src/state/use-composer-drafts.ts, apps/mobile/src/state/use-composer-drafts.test.ts
Stores, hydrates, normalizes, clears, and migrates last-used runtime modes for logical projects and project keys.
New-thread runtime-mode integration
apps/web/src/hooks/useHandleNewThread.ts, apps/web/src/components/ChatView.tsx, apps/mobile/src/features/threads/new-task-flow-provider.tsx, apps/mobile/src/state/use-thread-composer-state.ts
Uses the resolver for new drafts, carries modes only within the same logical project, persists selections, and writes resolved modes to drafts and queued messages.
Default access settings UI
apps/web/src/components/settings/ProjectDefaultsSettings.tsx, apps/web/src/components/settings/SettingsPanels.tsx, apps/web/src/components/settings/settingsSearch.ts
Adds the “Default access” selector, validation, mixed-machine handling, restore behavior, persistence, and search entry.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~20 minutes

Severity of issue fixed: Low

Merge Risk: 🔵 Low · up to 8be0f

Mobile users may be unable to save an access-mode change for a selected thread while its project metadata is temporarily unavailable. The issue is bounded but should be corrected before relying on the new preference behavior.

resurrected draft’s own runtime mode (from emptyStoredDraftThread.runtimeMode or
the composer draft’s stored mode) as draftRuntimeMode when calling
resolveNewThreadRuntimeMode. Ensure this value takes precedence before
resolvedRuntimeMode is written through setDraftThreadContext, setRuntimeMode,

Keep mobile last-used access mode on logical project identity, stop
persisting implicit defaults as last-used on submit, and preserve an
empty draft's explicit composer mode when resurrecting on web.

The resurrect test stubs a concrete last-used mode, but the hoisted mock
was inferred as null-only and failed apps/web typecheck in CI.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Keep the draft update available when project metadata is absent.

When selectedThreadKey exists but selectedThreadProject is null, Line 594 returns before updateComposerDraftSettings. The runtime-mode picker then cannot update the selected thread's composer draft. Update the draft after checking selectedThreadKey. Guard only last-used persistence on selectedThreadProject.
