AgentBBS cross-host agent federation for ruflo (ADR-164). Phase 1 exposes room coordination — federation_bbs_register / federation_bbs_publish / federation_bbs_watch / federation_bbs_human_join. Phase 2 (v3.40.0) adds signed cross-host federation — federation_bbs_identity (persistent Ed25519 node identity), federation_bbs_peer_add (pin a peer by nodeId + public key), federation_bbs_peers (audit/unpin), federation_bbs_serve (read-only pull endpoint), and federation_bbs_sync (pull pinned peers and union-merge what verifies). Every merged envelope is Ed25519-verified against a pinned key; unsigned/misattributed/oversize/over-hop envelopes are dropped and counted. Transport is HTTP pull and works on any network (Tailscale, LAN, VPN, loopback) — no tailnet required. Coordinates work ownership via claim messages (ClaimIssued/Released/Handoff/Ack). agentbbs lives in optionalDependencies; every handler gracefully degrades to {degraded:true} when the package is missing (ADR-150 pattern). As a mod (ADR-445 pattern): a tighten-only tool guard, a local slash command, and a status file the console shows.

Claude Code mod that holds risky Bash commands (rm -r, force push, migrations) and shows what they would delete before running, cancelling after 60 s with no answer.
