+# Plan 09-01 Summary
+
+**Tablo-owned etapes with a working Tasks tab chip filter and task create assignment path**
+
+## Accomplishments
+
+- Added `0007_etapes.sql` with no nested parent field and `tasks.etape_id ON DELETE SET NULL`.
+- Added etape sqlc queries and extended task queries to read, insert, and preserve `etape_id`.
+- Added protected etape create routes and a compact Tasks tab etape strip with `All`, `Unassigned`, and per-etape chips.
+- Added etape filtering while preserving the existing four status columns.
+- Extended task creation so submitted etape ids are validated against the current tablo before insert.
+
+## Task Commits
+
+1. **Task 1: Add RED coverage for first etape slice** - `a8a3e5f`
+2. **Task 2: Implement create-filter-assigned-task slice** - `565bb88`
+
+## Verification
+
+- `cd backend && go test ./internal/web -run 'TestEtapeCreateRendersChipAndCount|TestTaskCreateAssignsEtape|TestEtapeFilterRendersExistingKanbanColumns' -count=1`
+- `cd backend && go test ./internal/web -count=1`
+- `cd backend && go test ./... -count=1`
+
+## Deviations from Plan
+
+None. The slice stayed within the planned schema, handlers, and template surface.
+
+## Issues Encountered
+
+Sqlc returned row-specific task types when `etape_id` was selected before timestamp columns. The task queries now select and return columns in the generated `Task` model order, keeping existing handler/template code on `sqlc.Task`.
+
+## User Setup Required
+
+None.
+
+## Next Phase Readiness
+
+Plan 09-02 can build directly on the etape query and fragment surface to add edit, delete, and reorder. Deleting etapes should rely on the migration-level `ON DELETE SET NULL` behavior already in place.
+
+## Self-Check: PASSED
