Addresses the reviewer's blocker (comment 15915): release() unconditionally unlinked restart.lock, so after a stale/max-wait break an OLD owner could delete a NEWER owner's lock, letting a third restart interleave and defeating the guard. - Each acquire writes a unique owner token (randomUUID) into the lock file. - release() only unlinks while that token is still on disk; once another caller has broken and re-owned the lock, the timed-out original owner's release() is a no-op and leaves the new owner's lock intact. - Breaking a stale/timed-out lock now takes ownership atomically via write-temp + rename (atomic replace) instead of a blind unlink-then-recreate; a breaker that loses a concurrent takeover reads back a foreign token and keeps waiting rather than assuming ownership. Regression test (does not let a timed-out owner drop a lock another restart broke and re-owned) reproduces the three-restart interleave: R1 hangs (stale), R2 breaks + re-owns, R1.release() must NOT drop R2's lock. Fails on the old blind-unlink path (ENOENT), passes now. Also adds explicit single-agent restart-path guard coverage (review should-fix).

Headless / CI Installation
Set MOSAIC_ASSUME_YES=1 (or ensure stdin is not a TTY) to skip all interactive prompts. The following environment variables control the install:
Gateway configuration (mosaic gateway install)
| Variable | Default | Required |
|---|---|---|
MOSAIC_STORAGE_TIER |
local |
No |
MOSAIC_GATEWAY_PORT |
14242 |
No |
MOSAIC_DATABASE_URL |
(none) | Yes if tier=team |
MOSAIC_VALKEY_URL |
(none) | Yes if tier=team |
MOSAIC_ANTHROPIC_API_KEY |
(none) | No |
MOSAIC_CORS_ORIGIN |
http://localhost:3000 |
No |
Admin user bootstrap
| Variable | Default | Required |
|---|---|---|
MOSAIC_ADMIN_NAME |
(none) | Yes (headless) |
MOSAIC_ADMIN_EMAIL |
(none) | Yes (headless) |
MOSAIC_ADMIN_PASSWORD |
(none) | Yes (headless) |
MOSAIC_ADMIN_PASSWORD must be at least 8 characters. In headless mode a missing or too-short password causes a non-zero exit.
Example: Docker / CI install
export MOSAIC_ASSUME_YES=1
export MOSAIC_ADMIN_NAME="Admin"
export MOSAIC_ADMIN_EMAIL="admin@example.com"
export MOSAIC_ADMIN_PASSWORD="securepass123"
mosaic gateway install
Hooks management
After running mosaic wizard, Claude hooks are installed in ~/.claude/hooks-config.json.
mosaic config hooks list # Show all hooks and enabled/disabled status
mosaic config hooks disable PostToolUse # Disable a hook (reversible)
mosaic config hooks enable PostToolUse # Re-enable a disabled hook
Set CLAUDE_HOME to override the default ~/.claude directory.
