chore: bump version to 0.2.0rc15 for musehub#113 fix release
Sonnet 4.6
patch
15 days ago
| 1 | """MuseHub release persistence adapter — single point of DB access for releases. |
| 2 | |
| 3 | This module is the ONLY place that touches the ``musehub_releases`` table. |
| 4 | Route handlers delegate here; no business logic lives in routes. |
| 5 | |
| 6 | Releases tie a semver tag (e.g. "v1.2.3") to a commit snapshot and carry |
| 7 | structured metadata: distribution channel, parsed semver components, |
| 8 | AI provenance fields, and an auto-generated changelog. |
| 9 | |
| 10 | Boundary rules: |
| 11 | - Must NOT import state stores, SSE queues, or LLM clients. |
| 12 | - May import ORM models from musehub.db domain-specific modules. |
| 13 | - May import Pydantic response models from musehub.models.musehub. |
| 14 | - May import the packager to resolve download URLs. |
