ci/woodpecker/push/ci Pipeline was canceled
WIP — not for merge yet. Implements the core of the custom Pi harness (R14/R15): - runtime/pi/mosaic-extension.ts: native heartbeat — writes the same .hb contract (ts/pid/status[/model]) on a MOSAIC_HEARTBEAT_INTERVAL timer; turn_start/turn_end flip status busy/ok; model self-report via ctx.model; touches a .hb.native precedence marker. Also FIXES a latent bug: session_end -> session_shutdown (the old handler never fired) + corrects the import scope to @earendil-works/pi-coding-agent. - start-agent-session.sh: sidecar DEFERS when the .hb.native marker is fresh (< 2x interval), else writes the fallback — native precedence, sidecar fallback, same contract so fleet ps is agnostic (per Lead's design). Generated script validated (bash -n) + deferral/fallback behavior tested. REMAINING before PR: surface model in `fleet ps` (parseHeartbeat + row); vitest for the native-HB writer; "proper tool usage" (registerTool) piece; rebase onto #599's %q sidecar (overlap on the printf line).

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.
