fix(auth): show connection permissions and enforce session lifetime

[juliusmarminge]

Clients cannot inspect their own effective permissions, and settings failures do not consistently identify which environment rejected a save. Revoking or expiring a session also leaves its existing WebSocket open.

Show this client's allowed and missing permissions in Connections and mobile environment route details, tied to the active route. Name environments in settings denials and report both failed and successful targets for partial saves. Close live WebSockets on revocation, replacement, or expiry, including revocation during upgrade setup.

The revocation approach builds on Bear Huddleston’s #13844, with credit retained in the commit. This PR adds expiry and subscribes before rechecking persisted session state. It does not change T3 Connect grants or combine direct and T3 Connect sessions.

Validation: 60 focused auth/settings tests passed; server, web, and mobile typechecks passed; targeted lint passed with existing warnings. In the isolated test app, revocation closed an already-open WebSocket with code 1000 and the revoked bearer credential subsequently reported unauthenticated. Web permission visibility was verified with a restricted session. Native mobile UI was typechecked, not simulator-tested.

The original view below has no permission details. The current view shows the primary permissions grouped with environment settings and a remote environment with separate Routes and Permissions toggles. Remote routes and permissions expand inline without nested cards.

Implemented with GPT-6 Astra through the Codex harness in T3 Code.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR changes authenticated WebSocket lifetimes and session invalidation behavior in the server, while adding permissions visibility across clients. Because it directly modifies authentication code and introduces security-sensitive runtime behavior, human review is required.

📝 Walkthrough

Walkthrough

The changes add WebSocket session invalidation handling, display authentication scope grants in environment settings, and provide environment-specific feedback for settings save failures.

Changes

WebSocket session invalidation

Layer / File(s)	Summary
Session invalidation and WebSocket handling apps/server/src/auth/SessionStore.ts, apps/server/src/ws.ts, apps/server/src/auth/SessionStore.test.ts	The session store waits for session removal or credential expiry. The WebSocket handler races this wait against the RPC connection effect. Tests cover invalidation and expiry behavior.

Environment permissions and settings feedback

Layer / File(s)	Summary
Shared scope options and permission displays packages/shared/src/authScopeOptions.ts, packages/shared/package.json, apps/web/src/components/settings/SessionPermissions.tsx, apps/web/src/components/settings/ConnectionsSettings.tsx, apps/web/src/components/settings/EnvironmentRoutesList.tsx, apps/mobile/src/features/settings/EnvironmentRoutesSection.tsx, docs/user/remote-access.md	The shared scope options are used to show grant status in mobile and web environment settings. The display distinguishes checked permissions from permissions that have not been checked. The remote-access guide describes the route scope of the displayed permissions.
Environment-specific settings save feedback apps/web/src/components/settings/scopedSettings.ts, apps/web/src/components/settings/scopedSettings.test.ts, apps/web/src/components/settings/settingsLayout.tsx, apps/web/src/components/settings/useScopedSettings.ts, apps/web/src/hooks/useSettings.ts, apps/web/src/hooks/useSettings.sync.test.tsx	Scoped save results include successful environments and failure messages. Permission warnings and save error toasts identify affected environments and report available error details.

Merge Risk: 🔵 Low · up to ab9ac

After a route switch, the permissions panel may briefly show the previous route's grants as if they applied to the new route. The effect is informational only and short-lived, so it is safe to merge with owner awareness.
