Ambient Relay proves Discord-shaped automation without contacting Discord: four versioned synthetic events move through strict normalization, bot/DM/allowlist/cooldown policy, deterministic local stations, and body-free receipts. Every drafted reply is visibly NOT SENT.
Verification: 14 focused tests, deterministic terminal-artifact drift check, syntax and secret scans, zero dependency audit findings, and public SHA-pinned CI.
Live Discord observe/send code is experimental and unverified. Send mode requires an exact guild/channel allowlist and literal acknowledgement; read SECURITY.md before using it.
