This allows users to track, view, switch between, and manage all `spotlight run` instances from any Spotlight UI or via the `spotlight list` CLI command. + +## Completed Features + +### 1. Instance Registry ✅ + +**Location:** `src/server/registry/` + +- **Files Created:** + - `types.ts` - Type definitions for instance metadata and health status + - `utils.ts` - Utility functions for registry operations and PID verification + - `manager.ts` - Main registry manager class with CRUD operations + +**Key Features:** +- Stores instance metadata in `/tmp/spotlight-$USER/instances/` +- Tracks PID with start time to prevent false positives from PID reuse +- Robust health checking with 3-tier verification: + 1. HTTP healthcheck endpoint (fastest) + 2. PID validation with start time + 3. Status determination (healthy/unresponsive/dead/orphaned) +- Automatic cleanup of stale instances + +### 2. Instance Registration in `cli/run.ts` ✅ + +**Modifications:** +- Added `pidusage` dependency for cross-platform process info +- Generates unique instance ID with `uuidv7()` +- Captures PID and start time for both spotlight and child process +- Registers instance metadata after process spawn +- Pings control center at `localhost:8969` (fire-and-forget) +- Automatic cleanup on exit via signal handlers + +### 3. CLI List Command ✅ + +**File Created:** `src/server/cli/list.ts` + +**Modifications:** +- Added command to `src/server/cli.ts` +- Updated help text in `src/server/cli/help.ts` + +**Supported Formats:** +- `human` (default) - Uses existing `formatLogLine()` formatter +- `json` - Structured JSON output +- `logfmt` - Key-value pairs +- `md` - Markdown table + +**Usage:** +```bash +spotlight list # List healthy instances +spotlight list --all # Include unresponsive/orphaned +spotlight list --format json # JSON output +spotlight list --format md # Markdown table +``` + +### 4.
