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>

|
purpose: Receives demodulated FFSK bitstream from GNU Radio, indentifes
|
|
potential packets, and passes them to decoder classes for
|
|
parsing and verification. Finally human-readable data are printed
|
|
to stdout.

|
|
Requires eot_decoder.py and helpers.py
