 - When introducing new metadata sources (e.g., `SrcOllama`, `SrcOpenAI`), define them in both `internal/entity/src.go` and the frontend lookup tables (`frontend/src/common/util.js`) so UI badges and server priorities stay aligned.
 - Vision worker scheduling is controlled via `VisionSchedule` / `VisionFilter` and the `Run` property set in `vision.yml`. Utilities like `vision.FilterModels` and `entity.Photo.ShouldGenerateLabels/Caption` help decide when work is required before loading media files.
 - Logging: use the shared logger (`event.Log`) via the package-level `log` variable (see `internal/auth/jwt/logger.go`) instead of direct `fmt.Print*` or ad-hoc loggers.
+- Audit outcomes: import `github.com/photoprism/photoprism/pkg/log/status` and end every `event.Audit*` slice with a single outcome token such as `status.Succeeded`, `status.Failed`, `status.Denied`, or other constants defined there (no additional segments afterwards).
+- Error outcomes: when a sanitized error string should be the outcome, call `status.Error(err)` instead of adding a placeholder and passing `clean.Error(err)` manually.
 - Cluster registry tests (`internal/service/cluster/registry`) currently rely on a full test config because they persist `entity.Client` rows. They run migrations and seed the SQLite DB, so they are intentionally slow. If you refactor them, consider sharing a single `config.TestConfig()` across subtests or building a lightweight schema harness; do not swap to the minimal config helper unless the tests stop touching the database.
 - Favor explicit CLI flags: check `c.cliCtx.IsSet("<flag>")` before overriding user-supplied values, and follow the `ClusterUUID` pattern (`options.yml` → CLI/env → generated UUIDv4 persisted).
 - Database helpers: reuse `conf.Db()` / `conf.Database*()`, avoid GORM `WithContext`, quote MySQL identifiers, and reject unsupported drivers early.

+- When emitting audit logs, reuse the helpers in `pkg/log/status`; call `status.Error(err)` whenever the sanitized error message should serve as the outcome token. See `AGENTS.md` and `specs/common/audit-logs.md` for full guidelines.
