|
|
1. ✅ Installation metadata tracking (database table + repository)
|
|
2. ✅ Pack storage management with versioning
|
|
3. ✅ Checksum generation CLI command

5. ✅ Integrity verification utilities
|
|
|

|
|
|
|
## Key Deliverables
|
|
|
|
### 1. Database Schema
|
|
- **Migration:** `20260122000001_pack_installation_metadata.sql`
|
|
- **Table:** `pack_installation` (18 columns)
|
|
- Tracks: source, checksum, timestamp, user, method, storage path
|
|
|
|
### 2. Installation Metadata System
|
|
- **Model:** `PackInstallation` + `CreatePackInstallation`
|
|
- **Repository:** `PackInstallationRepository` (195 lines)
|
|
- Full CRUD operations with specialized queries
|
|
|
|
### 3. Storage Management
|
|
- **Module:** `crates/common/src/pack_registry/storage.rs` (394 lines)
|
|
- **Features:**
|
|
- Versioned storage: `{base_dir}/{pack_ref}-{version}/`
|
|
- Atomic install/uninstall operations
|
|
- SHA256 checksum calculation for directories and files
|
|
- Deterministic hashing with sorted file order
|
|
|
|
### 4. CLI Checksum Command
|
|
- **Command:** `attune pack checksum <path>`
|
|
- **Outputs:** Table, JSON, YAML formats
|
|
- **Flag:** `--json` generates registry index entry template
|
|
- Helps pack authors generate checksums for publishing
|
|
|
|
### 5. Enhanced API Endpoint
|
|
- **Updated:** `POST /api/v1/packs/install`
|
|
- **New Flow:**
|
|
1. Install to temp location
|
|
2. Register in database
|
|
3. Move to permanent versioned storage
|
|
4. Calculate checksum
|
|
5. Store installation metadata
|
|
6. Cleanup temp files
|
|
|
|
### 6. Error Handling
|
|
- **Added:** `Error::Io` variant to common error enum
|
|
- **Helper:** `Error::io()` constructor
|
|
- **Integration:** API middleware handles I/O errors
|
