+## Telegram commands (live)
+
+`/ss` `/status` `/pause` `/resume` `/resume force` `/3` (interval min) `/stop`
+
+- `/resume` clears only user pause; Canary drift requires `/resume force`.
+- Drift-pause now emits a single Telegram alert (was silent pre-refactor — root cause of the 2026-04-17 hang).
+
+## Operating-hours config
+
+`[options.operating_hours]` in TOML: `enabled`, `timezone` (NYSE local, e.g. `America/New_York`), `weekdays`, `start_hhmm`, `stop_hhmm`. Timezone validated at load; `_tz_cache` reused per tick. Boundary crossings log `market_open` / `market_closed` and notify once. Startup in-window is silent.
+
+## Phase-skip backstop
+
+`[options.alerts] fire_on_phase_skip = true` (default) — ARMED→light_*  direct (dark_* missed) still emits a `⚠️ PHASE SKIP` alert using FSM lockout to suppress spam.

 7. At `--stop-at` (or `--duration`): **"ATM stopped" ping**, then exit.
 
 Per-cycle behaviour:
-- Canary drift → auto-pause (logs `paused`, skips detection). Clear by running `atm run` again with the pause-file removed.
+- Canary drift → auto-pause + **single-shot Telegram alert** (`⚠️ Canary drift=N — monitorizare pauzată`). Clear via `/resume force` in Telegram, or restart with pause-file removed.
 - Detector reports UNKNOWN → stays in current state (logged as `noise`).
 - Colour change → full frame saved to `samples/YYYYMMDD_HHMMSS_<color>.png` (for corpus).
 - FIRE (BUY/SELL, not locked) → annotated PNG saved to `logs/fires/`, attached to the alert, `LevelsExtractor` armed.
+- **Phase skip backstop** (`fire_on_phase_skip=true` default) → ARMED → light_red/light_green direct (dark_red/dark_green missed) still emits `⚠️ PHASE SKIP` alert with screenshot. FSM lockout suppresses spam.
 - Phase-B complete → "Levels SL=… TP1=… TP2=…" push.
 - Heartbeat every `heartbeat_min` minutes.
 
+### Operating hours window
+
+Configure via `[options.operating_hours]` in TOML (source of truth: NYSE local time, timezone-aware so DST is handled automatically):
+
+```toml
+[options.operating_hours]
+enabled     = true
+timezone    = "America/New_York"     # fail-fast validated at config load
+weekdays    = ["MON", "TUE", "WED", "THU", "FRI"]
+start_hhmm  = "09:30"                # NYSE open
+stop_hhmm   = "16:00"                # NYSE close
+```
+
+Out-of-window ticks are skipped (logged only on transition). On boundary crossings the bot emits `market_open` / `market_closed` Telegram status messages exactly once per transition. **Startup in-window does not emit a spurious `market_open` alert.**
+
+CLI overrides (beat TOML):
+
+```
+atm run --tz America/New_York --weekdays MON,TUE,WED,THU,FRI --oh-start 09:30 --oh-stop 16:00
+```
+
+> `--oh-start / --oh-stop` are **different** from `--start-at / --stop-at`. The `--start-at / --stop-at` pair controls wall-clock session bounds (when the process starts and quits); `--oh-*` controls the NYSE trading window inside the session (what hours detection actually runs). They compose.
+
+### Telegram commands
+
+Send to the bot chat:
+
+| Command | Effect |
+|---|---|
+| `/ss` or `/screenshot` | Take and send a screenshot now |
+| `/status` | State + pause reason + window open/closed |
+| `/pause` | Suspend detection (heartbeats continue) |
+| `/resume` | Clear user pause only. If Canary is drift-paused it **stays paused** — use `/resume force` |
+| `/resume force` | Also clear Canary drift-pause (use after recalibration) |
+| `/3` or `/interval 3` | Set auto-screenshot interval to 3 min |
+| `/stop` | Stop the scheduler |
+
+Only `allowed_chat_ids` are accepted. After 3 consecutive `401`s the poller enters degraded mode.
+
+### Calibration validation (offline gate)
+
+Validate that the current calibration classifies known-labeled frames correctly **without waiting for a live session**:
+
+```bash
+atm validate-calibration samples/calibration_labels.json
+```
+
+Input JSON:
+```json
+[
+  {"path": "logs/fires/20260417_201500_arm_sell.png", "expected": "yellow", "note": "first arm"},
+  {"path": "logs/fires/20260417_205302_ss.png",       "expected": "dark_red"},
+  {"path": "logs/fires/20260417_210441_ss.png",       "expected": "light_red"}
+]
+```
+
+Output: per-sample PASS/FAIL with detected color + top-3 candidates by RGB distance + suggestion pixels for misclassifications.
+
+Exit code: `0` if 100% PASS, `1` on any FAIL, `2` on malformed/missing input. Suitable for CI or a pre-`atm run` sanity check.
+
 Keep PowerShell minimized during the session so it doesn't cover TradeStation.

 - [ ] **Coverage report**: run `pytest --cov=atm --cov-report=term-missing`, aim for ≥ 85% per module.
 - [ ] **Typing strictness**: run `pyright src/` with strict mode, fix reported issues.
 - [ ] **Perf baseline**: profile one detection cycle on a representative frame; ensure < 100ms so 5s loop has ample headroom.
+- [ ] **Exchange calendar holidays**: operating_hours doesn't know about NYSE closures (MLK, Thanksgiving, Good Friday). User `/pause`s manually for now.
