Replace all print() calls with structured logging using the Python logging module. This provides: - Named loggers per subsystem: commander_ai_lab.api, .batch, .sim, .coach, .deckgen, .collection, .scanner, .ml, .cache, .pplx - Dual output: console (StreamHandler) + rotating file (RotatingFileHandler) at logs/commander-ai-lab.log (25 MB x 5 backups = 125 MB max) - Configurable via env vars: CAL_LOG_DIR, CAL_LOG_MAX_MB, CAL_LOG_BACKUP_COUNT - --verbose / -v flag for DEBUG-level output - overnight-run.py: separate rotating log at logs/overnight-run.log (10 MB x 5) - Sub-module loggers in ml/, scanner/, deck_sources/, src/ all propagate to the root commander_ai_lab logger - Stripped redundant [TAG] prefixes from messages (logger name carries context) - Format: '2026-03-13 14:00:00 INFO [commander_ai_lab.batch] message' Files changed: lab_api.py, overnight-run.py, and 11 sub-module .py files 176 total print() calls converted (101 in lab_api.py, 76 in sub-modules)

Commander AI Lab — Training Dataset Builder
|
|
════════════════════════════════════════════
|
|
Reads ML decision JSONL files, encodes states, labels actions,
|
|
and produces a training-ready dataset saved as NPZ.
|
|
|
|
Usage:
|
|
python -m ml.data.dataset_builder --results-dir results/ --output ml/models/dataset.npz
|
|
|
|
Output NPZ structure:
|
|
states: float32 (N, 6177) — encoded state vectors
|
|
labels: int64 (N,) — macro-action indices (0-7)
|
|
game_ids: object (N,) — game ID for each sample
|
|
outcomes: object (N,) — game outcome per sample
|
|
playstyles: object (N,) — deck archetype per sample
