test(calibration): 8 labels + 3 scenarii noi (inclusiv regresie 2026-04-21)

calibration_labels.json: 16 → 24 entry-uri. Toate cele 8 frame-uri dumpate
automat de live loop azi (gray×5, dark_green×1, yellow×1, dark_red×1) trec
prin validate-calibration cu detector-ul curent (24/24 PASS).

scenarios.json: 8 → 11 scenarii:

1. buy_catchup_opposite_rearm_to_sell — REGRESSION pentru bug-ul de azi.
   Trace real din log: 17:00 catchup dark_green → PRIMED_BUY (synth arm+prime),
   apoi 17:45 yellow → ARMED_SELL via opposite_rearm. Verifică că dispatch-ul
   nou emite kind=opposite_rearm și că scheduler-ul se oprește.

2. buy_armed_gray_persist — gray între arm și prime ține ARMED_BUY
   (reason=persist). Acoperă o ramură FSM neacoperită.

3. buy_primed_gray_cooldown — gray după prime ucide ciclul (reason=cooled,
   IDLE, scheduler stop). Confirmă semantica M2D că chart-ul tăcut post-prime
   înseamnă setup expirat.

Total: 11/11 scenarii PASS, 238/238 teste (235 + 3 noi scenarii regresie).

 ## Calibration corpus
 
-`calibration/` — persistent, auto-suficient, safe to keep când `samples/` și `logs/fires/` se golesc. Conține:
+`calibration/` — persistent, auto-suficient. Conține:
-- `frames/` — PNG-uri `{ts}_{color}.png` (ground truth în nume)
+- `frames/` — PNG-uri raw `{ts}_{color}.png` scrise **automat** de live loop la fiecare schimbare de culoare (filename = culoarea detectată, poate fi greșită)
-- `calibration_labels.json` — gate offline pentru `atm validate-calibration`
+- `calibration_labels.json` — ground truth **manual** (gate offline pentru `atm validate-calibration`)
 - `scenarios.json` — secvențe FSM pentru `tests/test_scenarios_regression.py`
 
-Când adaugi un frame: copiezi din `logs/fires/` → redenumești `{ts}_{color}.png` → adaugi entry în JSON. Validare după orice recalibrare.
+Workflow după sesiune: review frame-urile noi din `frames/`, adaugi entry-uri în `calibration_labels.json` cu culoarea pe care ai văzut-o TU pe chart (nu neapărat cea din filename), rulezi `atm validate-calibration`.
