Add `mosaic fleet comms-block <role> [--host]` — an explicit-arg, comms-only emitter wrapping a new resolveCommsBlock() over readFleetCommsBlock. Unlike the launch-time reader (which returns '' on any miss so composeContract can no-op silently), the emitter fails loud: unknown role / missing roster → stderr + exit 1, so an operator can safely preview any peer's view and a typo is never a silent no-op. Add docs/fleet/FLEET-LAUNCH.md: the canonical roster-driven launch path (worker + orchestrator .env fold via MOSAIC_AGENT_COMMAND, which short-circuits the line-44 yolo hardcode), 3 launch gotchas (flag conflict, MOSAIC_AGENT_NAME baking, launchRuntime guards), the #632 preserve-list note, and the North-Star A→B→webUI launch-config arc. PATH A of the orchestrator-launch fix; PATH B (roster-native launch-config: yolo toggle + command/channels emission) tracked as #636. TDD: 6 new resolveCommsBlock cases; 177 fleet+comms tests green; typecheck, eslint, prettier clean.

mosaic gateway install # Install the gateway daemon
mosaic config show # View current configuration
mosaic config hooks list # Manage Claude hooks
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.
