* Adopt /api/health REST route (issue #713)
Cheap liveness probe on the connection screen: GET /api/health surfaces
backend version + auth mode (Token vs Gated/OAuth) without the heavier
/api/status payload. Added HermesApiService.getHealth + HealthStatus model;
ConnectViewModel.loadHealth probes on open (best-effort, silent on failure);
ConnectScreen shows a read-only health card when reachable.
Verified: ktlint clean, assembleDebug BUILD SUCCESSFUL locally.
* Add used/full context meter to chat screen
Shows session prompt tokens vs model context window above the composer,
polled every 5s. Color-coded bar warns at 70%/90%.
* fix(chat): fix unit tests for context usage meter
Format >=100k tokens cleanly in ContextUsageChip and stub AuthManager profile ID in ChatViewModelTest.
* Fix context meter: source used tokens from input_tokens
Gateway /api/sessions/{id} has no last_prompt_tokens column; use
input_tokens instead. Show meter as soon as full context is known.
* Add tappable context breakdown sheet
Chip opens a bottom sheet with input/output/cache/read/write/reasoning
token rows + message count. Source breakdown from /api/sessions/{id}.
* Refresh context meter on streaming complete
Trigger fetchContextUsage immediately when a message finishes streaming
instead of waiting for the 5s session-sync poll.
* Fix context meter: source used tokens from live WS session.info
The REST /api/sessions/{id} endpoint reads the DB input_tokens column,
which is stale/0 for active sessions — that's why the meter was stuck at 0.
Switch the meter to the live values the gateway pushes over the WS
session.info payload after each turn:
- used = last_prompt_tokens (real used context for the turn)
- full = context_length (model-accurate window; keep /api/model/info as a
fallback before the first turn completes)
fetchContextUsage now only tops up the denominator from /api/model/info and
no longer overwrites the live WS value with the stale REST input_tokens.
The 5s poll remains as a fallback.
* Revert "Fix context meter: source used tokens from live WS session.info"
This reverts commit 932393fd80993d57e66fe93552a949460d646674.
