Public community release. The complete working system — DSP + decoders (scripts/), web dashboard + API (dashboard/), container stack (docker/), config templates (config/) — plus APOCALYPSE-EDITION.md, the full build guide for a human or a coding agent. GPLv3 (PyEOT dependency). Scrubbed of all secrets, internal IPs, hostnames, and location detail. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

# trim-captures — prune old VOICE capture audio from /tmp/airband, keeping the durable detection log.
|
|
# Safe by design: heard.jsonl (the detections Activity reads — channel + time) is SEPARATE and never
|
|
# touched; this only deletes bulky .mp3 audio AFTER it's logged. It forces an ingest first (GET /api/heard,
|
|
# which appends any new clip to heard.jsonl) and ABORTS if the dashboard is unreachable — so a not-yet-logged
|
|
# clip can never be deleted. --dry-run to preview.
