+## Block 02 Notes/Tags Breakpoint
+
+Adding real V1 task notes and freeform tags is a broad persistence change, not
+only a drawer read-model change. It would touch at least:
+
+1. `Task`, `Task.quickCapture`, and `Task.copyWith`.
+2. Task document fields and `TaskDocumentMapping`.
+3. Persistence contract field sets and document field coverage tests.
+4. In-memory application/repository round trips through the full domain object.
+5. SQLite Drift task table columns, generated database code, schema versioning,
+   migration strategy, migration tests, and both SQLite task mappers.
+6. Command/capture surfaces if the UI can create or edit notes/tags.
+
+Per `UI_PLAN_2_BLOCK_02_BACKLOG_READ_MODELS_AND_METADATA.md`, this is the
+breakpoint where Ashley needs to choose whether drawer tags should be read-only
+placeholders for now or true V1 metadata with a schema migration.
