+## Work Activity Daily Report Layer (2026-06-26)
+
+The personal daily report is derived from two inputs:
+
+- `work-activities`: append-only activity records created by successful business actions.
+- `task-worklogs`: legacy/manual worklog records that still contribute hours and written work content.
+
+`work-activity-factory.ts` owns the mapping from domain actions to reportable activity semantics. Zustand stores call this factory after a successful operation, then append the result through `useWorkActivityStore`.
+
+`workspace-daily-report.ts` remains a pure aggregation engine. It groups today's current-user activity into delivery, progress, creation, risk, and note sections, and also detects in-progress work that started before today but has no activity or progress note today.
+
+This is intentionally not a generic rules engine or event bus. The rule surface is explicit, typed, and local to the workspace/daily-report use case.
