- IChatSession/IChatTurn interfaces: add optional numCtx field
- Mongoose schemas: add numCtx field to ChatSession and ChatTurn
- API controller: validate numCtx (>=16384, multiple of 8192)
- ChatSessionService: persist numCtx on session, pass through to turn
- SessionPanel: add range slider for Context Window (hidden for OpenAI)
- Drone buildDroneModelConfig: prefer turn.numCtx over model defaults
- Switch frontend sign-in to /api/v1/auth/sign-in endpoint (includes persona)
- Add updateUser() to App context for proper state management
- Fix Settings.tsx save flow to use updateUser() instead of broken localStorage merge
- Remove unused web AuthController (gadget-code/src/controllers/auth.ts)
- Fix UserApiControllerV1 to return flat user object instead of double-wrapped
- Remove SessionType enum and references (dead code)
- Add proper server sign-out call before clearing local state
Resolves issue where User Settings view didn't display persona text even though it existed in the database.
The persona field was missing from both the session object and the API
response during sign-in, causing User Settings to display an empty field
even when the user had a persona defined in the database.
This commit addresses two interrelated issues causing drones to
de-register and users to be forcibly signed out:
## Heartbeat Timeout Fixes
1. Move heartbeat interval to a Web Worker (not subject to browser
tab throttling). Chrome throttles setInterval in background tabs
to ~1/min, which causes the 19s heartbeat to miss the drone's
timeout timer. The Web Worker fires reliably regardless of tab
visibility.
2. Add visibilitychange handler: when the tab becomes visible again,
send an immediate heartbeat to reset the drone's timer after any
throttling that may have occurred.
3. Fix onReleaseSessionLock to clear the heartbeat timer. Previously,
releasing the lock left the 60s timer running, causing a spurious
timeout and status emit after the lock was already released.
4. Increase drone heartbeat timeout from 60s to 120s. With the Web
Worker fix, heartbeats should be reliable, but doubling the timeout
provides a generous safety margin.
5. Add socket disconnect/reconnect handlers on the drone side. On
disconnect, clear the heartbeat timer. On reconnect, re-emit drone
status so the platform knows the drone is alive.
6. Configure Socket.IO pingInterval/pingTimeout explicitly (25s/60s)
instead of relying on defaults.
## JWT Expiration Fixes
1. Increase WebToken DB record expiration from 1 hour to 7 days. The
1-hour expiration was the real session lifetime gate (the JWT crypto
exp was already 24h), and it was far too aggressive for a dev tool.
2. Fix web /auth/renew-token endpoint to use req.user from the session
cookie instead of verifyJsonWebToken(req.body.token). This eliminates
the catch-22 where an expired token cannot be used to request its
own renewal.
3. Fix token refresh response parsing. The API v1 renew-token endpoint
returns { success: true, token } at the top level, but the frontend
was looking for json.data?.token, causing every refresh to fail.
4. Add proactive token refresh: check the JWT exp claim before each
request and refresh if expiring within 5 minutes. This avoids
unnecessary 401 errors and the resulting socket disconnections.
5. Update socket JWT on token renewal via a callback registered in
App.tsx. This ensures that future socket reconnections use the new
token instead of the expired one.
