Unit tests (4 files): - names.test.ts: pool size, uniqueness, allocation, short name resolution - registry.test.ts: atomic writes, lockfile, CRUD, liveness, spawn slots, failover - transport.test.ts: message creation, delivery, polling, dedup, pause filtering - guardrails.test.ts: strict/permissive/custom profiles, path checks, bash commands Integration tests (3 files): - mesh-lifecycle.test.ts: full register→communicate→deregister cycle, peer-to-peer - concurrent-spawn.test.ts: capacity limits, depth enforcement, placeholder reaping - coordinator-failover.test.ts: role transfer, inbox preservation, crash recovery Bug fix: pollInbox now tracks actual filenames instead of reconstructing them from msg.timestamp, fixing dedup failures when write time differs from message creation time. All 103 tests pass. Typecheck and lint clean. Co-authored-by: Yaniv Golan <yaniv@golan.name>

What
Full implementation of the cc-mess plugin as specified in
docs/internal/design.md— a file-based mesh networking system for multiple Claude Code instances.Why
Enables multiple Claude Code instances to discover each other, communicate, delegate tasks, share insights, and develop emergent trust relationships. Human observes and controls the mesh via Telegram integration.
How
Implements all 5 sub-projects from the design doc:
SP-1: Transport & Registry — File-based messaging under
~/.claude/channels/mess/, atomic writes via temp+rename, lockfile-protected registry, at-least-once delivery with persistent deduplication, heartbeat-based liveness detection.SP-2: MCP Server & Tools — 7 MCP tools (
send,broadcast,reply,list_instances,spawn,kill,update_self), channel notification formatting, poll-based inbox delivery.SP-3: Spawn & Guardrails — Process launch via
child_process.spawn()(no shell interpolation), 3 guardrail profiles (strict/permissive/custom), path canonicalization, spawn depth enforcement, atomic admission with placeholder reaping.SP-4: Telegram Relay — Event formatting, verbosity control (quiet/normal/verbose), status reports, human-to-instance message parsing,
/messcommand formatting.SP-5: Trust & Reputation — Documentation patterns for emergent per-instance trust via Claude Code memory.
Also includes: CI/CD workflows (lint/typecheck/test/release/CodeQL), GitHub config (issue templates, PR template, CODEOWNERS), project docs (README with mermaid diagram, CONTRIBUTING, SECURITY, CHANGELOG, LICENSE), hook scripts, skill files, and plugin configuration.
