All checks were successful
ci/woodpecker/pr/ci Pipeline was successful
Second- and third-round independent-review reliability fixes on the keep-mode
upgrade rollback path, plus accurate abort messaging. All fixed red-first with
self-verifying controls in the rollback gate.
Round 2 (blockers A/B, should-fix C):
- install.sh: `trap 'restore_snapshot; exit 1' ERR INT TERM` so an INT/TERM
mid-sync terminates instead of resuming past the interrupt and reporting
success (a bash signal handler that only returns does not terminate).
- manifest.{ts,sh}: reject a degenerate [framework] section whose entries are
all empty or bare-dot (`/`, `./`, `.`, `..`) — it passed the non-empty guard
yet yielded zero usable globs, silently resolving everything to operator.
Parity via a shared `[^/.]` usable-glob test; TS throws ManifestError.
- finalize.ts: classify the sync-abort message — a ManifestError is a pre-sync
validation abort ("no files were changed"); any other error may be partial.
Round 3 (blockers D1, D2):
- install.sh: enumerate framework files with a checked temp file (_scan_or_die)
instead of `< <(find …)` — process substitution discards find's exit status,
so an EACCES/I/O failure mid-scan would truncate the file list yet leave the
loop exiting 0, committing a partial upgrade as success (ERR trap never fires).
- install.sh: guard the `rm -rf; mkdir -p` target reset inside restore_snapshot
— a bare reset failing under set -e exits silently after partial deletion,
never printing the snapshot-recovery pointer. Now checked like the cp -a
restore: on failure it preserves the snapshot and tells the operator where.
Tests: rollback gate 14→28 (Parts C/D/E with disabled-guard controls);
new finalize-sync-abort.spec.ts (3). No secret value is ever emitted; snapshots
stay 0700. Gates green: typecheck, lint, format:check, full mosaic vitest 1094,
HARD GATE 193, rollback 28, migration 21.

CLI package for the Mosaic self-hosted AI agent platform.
Usage
mosaic wizard # First-run setup wizard
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.
