+## 0.3.4 - 2026-06-19
+
+- Completed Phase 2 refactoring: domain cleanup and value object extraction.
+  - Split durable job configuration (`domain.Job`) from transient execution state (`domain.JobRuntime`), keyed by job ID.
+  - Added `domain.Schedule` value object with `Parse`, `Validate`, and `Next(time.Time)` methods for cron/interval parsing.
+  - Migrated scheduler to parse schedules once at load/edit instead of per tick, removing duplicated parsing.
+  - Made `RunJob` pure: runner no longer mutates jobs, returning only `RunRecord` for the caller to fold into runtime state.
+  - Simplified `storage.normalizeJobs` to touch only durable configuration; runtime initialization moved to `domain.NewRuntime`.
+- No observable behavior changes; continued internal refactoring toward separated concerns.
