Counts + status words only β€” never message content. *Residual gap, honest by design:* router/handler rows stay undecorated β€” the engine keys its stage metrics by connection, so no per-router/per-handler runtime counter exists to show. + - **Amendment (2026-09-06, BACKLOG #1145) β€” the poll is now TOKENLESS, and the "auth is passive" sentence above describes only what shipped in July.** Passive there meant *never prompts*; it was not passive about the session's idle clock. `GET /connections` is gated by plain `require(Permission.MONITORING_READ)`, and `require()` resolves the bearer with `identity_for_token(bearer_token(request))` β€” the default `activity=True`, which refreshes the session's idle clock. Every other bearer-gated `require*` factory in `api/security.py` delegates to `require()`; `require_service_cert` is the one that does not, and it is cert-only, never a bearer. So a bearer on a 5-to-10-second timer refreshed the idle clock on every tick and would make the engine's 30-minute idle timeout unreachable for as long as a VS Code window stayed open (CWE-613). That is the rule `ide/src/statusBar.ts` already stated for its own 15s poll, so the two files gave opposite answers to one question. The bearer is now driven by `liveStatusModel.LIVE_STATUS_PLAN` (`authenticated: false`, asserted in CI) instead of an unconditional `peekToken`, and the 401 branch no longer clears the cached session β€” a tokenless 401 is the route demanding auth, not evidence the session died. **Accepted cost:** against an auth-enabled engine the rows stay undecorated, so decorations now land only where `/connections` answers tokenless (a dev or embedded engine under `allow_no_auth`). The setting ships OFF by default; the full monitor remains the web console at `/ui`, which reads the same data under `activity=False`. Making a bearer safe here would need an engine-side passive-read surface β€” no header, query parameter or route lets a *client* ask for `activity=False` today β€” which is a separate change. - [x] **Refresh** β€” shipped 2026-07-12: a config-dir `FileSystemWatcher` (`**/*.py`, `connections.toml`, `codesets/**/*.csv`; `ide/src/configWatcher.ts`) and the save handler both funnel into one debounced (750 ms, `configRefresh.ts` `RefreshCoalescer`) validate + graph + code-sets refresh, so an external edit (git pull, another tool) refreshes without double-firing against the save path; exec-gated (ADR 0035) exactly like the save handler.
