Owns the TypeBox/Ajv configuration schema for the validated config fields (E00-S04-T01); the environment adapter (E00-S04-T04), field-specific startup errors (E00-S04-T02) and secret redaction (E00-S04-T03) land in later tasks. |
 | `packages/` | `packages/database-postgres` (`@personal-blog/database-postgres`) | PostgreSQL database adapter package. Single owner of the `pg`/Kysely driver imports (E00-S03-T02); the migration ledger (`schema_migrations`, E00-S03-T03), the migration advisory lock (E00-S03-T04) and the migration runner with its failure diagnostic (E00-S03-T05) are implemented here. The server depends on this package to run the startup migrations behind its readiness gate (E00-S03-T06). |
