That leaves users without a +clear answer to the actual question they care about: is the broker still +running locally, are its state files stale, is the dashboard port occupied, or +do they just need to reconnect later after an approval/restart event? + +This task should make the TUI useful even when live dashboard-backed data is +down. The fallback does not need to reimplement the full Web UI API. It should +derive the best available local diagnosis from broker PID/socket/version files, +dashboard-port ownership, and any directly accessible local broker state, then +render that diagnosis explicitly as local fallback data. Live dashboard status +and stop control should still be used whenever the API is reachable. + +## Deliverables + +- Update `src/mcpbridge_wrapper/tui.py` so `BrokerTUIClient.fetch_snapshot()` + can return a structured local-fallback snapshot when dashboard requests fail. +- Add local fallback diagnostics that distinguish at least: + running broker without dashboard, foreign listener on the dashboard port, + stale local runtime files, and no local broker runtime. +- Update the TUI renderer so the screen clearly marks whether broker runtime + data comes from the live dashboard API or from local fallback state, and + whether stop control is unavailable in fallback mode. +- Add or extend tests in `tests/unit/test_tui.py` and `tests/unit/test_main_tui.py` + for fallback diagnosis, rendering, and existing `--tui` CLI behavior. +- Produce `SPECS/INPROGRESS/P7-T4_Validation_Report.md` with targeted and full + quality-gate evidence. + +## Success Criteria + +- TUI remains useful when the dashboard API is unavailable and still presents a + best-effort local broker diagnosis instead of only a generic unreachable + error. +- The screen explicitly distinguishes live dashboard-backed runtime data from + local fallback data. +- Users can infer from TUI alone whether they likely need to restart the + broker, free the dashboard port, clean stale files, or simply attach once the + dashboard comes back. + +## Test-First Plan + +1. Add `fetch_snapshot()` tests for unavailable dashboard requests where local + state indicates: + a running broker without dashboard, + a foreign listener on the dashboard port, + stale broker files, + and no live broker. +2.

The render path renders several fields (`upstream_pid`, `connected_clients`, `upstream_alive`, etc.) that will show as `n/a` in fallback mode. This is by design per the PRD ("bounded local-only broker view"), but an inline comment or docstring note would clarify this intentional limitation to future readers. +_Suggestion:_ Add a brief comment to `_build_local_fallback_broker` noting that fields not derivable from local files are intentionally omitted. + +**[Low] `service_name` uses raw string `"local-fallback"` as a status value** +`BrokerTUISnapshot.service_name` is re-used as both a display label and a status sentinel (`"local-fallback"`). This dual purpose is subtle; the render path uses it only for display and doesn't branch on it, so there is no practical bug, but it couples unrelated concerns. +_Suggestion:_ Acceptable as-is for now; could be separated in a future refactor. + +**[Nit] `test_fetch_snapshot_surfaces_runtime_errors` previously only asserted `available is False`** +The test was strengthened as part of this task (now also asserts `broker is None` and `runtime_source == "dashboard-unavailable"`), which is good. The original assertion was undershooting — this is a positive improvement. + +--- + +### Architectural Notes + +- The fallback is correctly read-only: `can_stop=False` is always set when the dashboard is unavailable, and `request_stop()` is never called from the TUI loop in fallback mode. This preserves the invariant that broker control only flows through the authenticated Web UI API. +- `_read_local_pid` + `_read_local_version` are pure helpers with no side effects, making them easy to test and reuse if a future doctor integration needs them. +- The three-tier `runtime_source` taxonomy (`"dashboard-api"`, `"local-fallback"`, `"dashboard-unavailable"`) is clean and stable. The render label mapping in `_runtime_source_label` ensures the user never sees the raw internal token. +- `render_screen` condition changed from `if snapshot.available and broker` to `if broker` — this is the correct gate for fallback mode, since `available` is always `False` when the dashboard is down but local data exists. The old condition was silently suppressing useful fallback output. + +--- + +### Tests + +- 38 TUI tests pass (5 new tests covering fallback paths). +- New tests are well-isolated using `patch` for `_read_local_pid`, `_read_local_version`, and `tail_log_lines`. +- `test_run_loop_does_not_call_stop_without_live_control` is a particularly valuable regression guard. +- Coverage: `tui.py` 96.1%, total 91.75% — above the 90% threshold. +- Uncovered lines in `tui.py` (470, 509–510) relate to `_display_value` edge path and `_read_local_pid` PermissionError branch — acceptable misses given the mock-based test strategy. + +--- + +### Next Steps + +- No blockers.
