+description: task.status hardcoded enum copies (frontend/app.js) drift from schema.py CHECK constraint; recurring skill_defect, not a one-off coder mistake
+metadata:
+  type: project
+---
+
+`src/schema.py`'s `task.status` CHECK constraint has grown a hardcoded mirror in at least two
+independent `frontend/app.js` locations: `TASK_STATUSES` (line ~979, `v_task_board` status
+filter dropdown, introduced 2026-07-31 commit `e026f9e`) and `NAV_STATUS_BUCKETS` (line ~214,
+nav-bar status summary, introduced 2026-08-07 commit `958b55a`). Both were correct when written
+but went stale the moment commit `ea19c7d` (2026-08-08, Org Graph unification Phase 1) added an
+11th status `reviewing_planner_output` to the schema — neither list was updated, and no test
+asserts the frontend lists match `schema.py`'s CHECK constraint.
+
+**Why:** confirmed via `git log -S`/blame that this exact drift pattern happened twice,
+independently, across two unrelated Units separated by a week — not a one-off mistake in a
+single Coder session. `skills/code-task-development/SKILL.md` (the Coder skill used for both)
+has no step instructing the Coder to grep for/update other hardcoded copies of a schema.py
+enum/CHECK-constraint list when adding or changing one. Filed as `root_cause_category:
+skill_defect` (not `coder`) for this reason on the nav-bar-project-context validation task
+(2026-08-13).
+
+**How to apply:** if a future validation surfaces another stale hardcoded status/enum list
+anywhere in `frontend/app.js` or elsewhere, treat it as the same recurring `skill_defect`
+(propagate to `c_org_loop_route`/whoever owns `skills/code-task-development/SKILL.md`) rather
+than re-filing as an isolated `coder` mistake each time. The actual fix (deriving the enum from
+one shared source, or a schema-consistency test) has not landed as of this writing — check
+`frontend/app.js` and `src/schema.py`'s CHECK constraint directly before assuming it's fixed.
