…ase 6 reclassification script Completes the subagent's prior commits by closing two gaps surfaced by TypeScript's exhaustive type checking on the TaskStatus enum after adding the umbrella kind's terminal state: 1. taskConstants.ts — add COMPLETED to the TaskStatus enum + TASK_STATUS_CHECKBOX (per-kind terminal state; analogous to DONE for implementation kind) 2. status-transitions.ts — add COMPLETED entry to VALID_TRANSITIONS with empty outgoing array; the per-kind gate dispatches before this table is consulted, so the entry exists for type completeness only (Record<TaskStatus, _> is exhaustive) 3. common-parameters.ts — extend the status Zod enum so MCP/CLI callers accept COMPLETED as a status value; the gate enforces kind-appropriate use 4. pg/meta/_journal.json — Drizzle journal timestamp regen artifact Also adds the Phase 6 reclassification script (scripts/reclassify-umbrella-tasks.ts): dry-run-by-default helper that flips kind="umbrella" on mt#1768, mt#1451, mt#1533, mt#1534, mt#1535, mt#1143 — the six pure-metadata umbrellas that motivated this task.

Substantial progress toward multi-kind workflows, but several critical gaps remain. Most importantly, COMPLETED was added to the TypeScript status enum without a matching Postgres enum migration — any attempt to persist COMPLETED will fail, breaking the umbrella workflow end-to-end. Unit tests also retain an invariant that now conflicts with the new COMPLETED status, causing a test failure. Additionally, markdown parsing/rendering does not handle COMPLETED checkboxes, and default task listing fails to treat COMPLETED as terminal. Address the DB enum migration, fix the test invariant or transitions map, complete the checkbox maps, and update listing filters (or derive from terminal sets) before merge. Non-blocking: consider extending the smoke test to actually write COMPLETED to DB to detect enum drift early.
Findings
- [BLOCKING] src/domain/storage/migrations/pg/0036_add_task_kind.sql:1 — Database enum drift:
TaskStatus.COMPLETEDadded in code but no migration alters Postgrestask_statusenum
src/domain/tasks/taskConstants.tsintroduces a new statusCOMPLETED, andsrc/domain/storage/schemas/task-embeddings.tsdefines thetask_statusenum fromObject.values(TaskStatus)— which now includes"COMPLETED". However, the only DB migration in this PR (src/domain/storage/migrations/pg/0036_add_task_kind.sql) adds thekindcolumn and does notALTER TYPE task_status ADD VALUE 'COMPLETED'. Without an enum migration, any attempt to persiststatus = 'COMPLETED'(e.g., transitioning an umbrella task toCOMPLETED) will fail at the DB layer with an enum-constraint error.
Evidence:
- New status value:
src/domain/tasks/taskConstants.ts(enum includesCOMPLETED). - Drizzle enum uses all
TaskStatusvalues:src/domain/storage/schemas/task-embeddings.tsdefinestaskStatusEnum("task_status", Object.values(TaskStatus)). - No enum alteration present in migrations;
0036_add_task_kind.sqlonly adds thekindcolumn.
Requested fix:
- Add a migration to alter the existing Postgres enum:
ALTER TYPE "task_status" ADD VALUE IF NOT EXISTS 'COMPLETED';(and ensure ordering if your migration tool requires it), or migrate to a text + check-constraint pattern. Update the Drizzle metadata journal accordingly. - [BLOCKING] src/adapters/shared/common-parameters.ts:290 — Parameter schema now accepts
COMPLETEDbut downstream persistence may reject due to missing enum migration
TheTaskParameters.status.schemawas expanded to include"COMPLETED"(seesrc/adapters/shared/common-parameters.ts:286-298). Coupled with the updatedvalidateStatusTransition()that permitsCOMPLETEDforumbrella, CLI/API callers can now pass this value. However, since the Postgrestask_statusenum was not migrated to includeCOMPLETED(see separate finding on0036_add_task_kind.sql),setTaskStatus()will attempt to write a value the DB enum doesn't allow, causing runtime failures.
Evidence:
- Acceptance stance in this PR allows
COMPLETEDfor umbrellas (testsstatus-transitions.test.tsand smoke script). setTaskStatus()writesstatusdirectly totasksTable.status(src/domain/tasks/minskyTaskBackend.ts:84-95), which maps to thetask_statusenum (src/domain/storage/schemas/task-embeddings.ts).
Requested fix:
- Block setting
COMPLETEDuntil the DB enum is migrated (preferably by adding the enum migration, as requested in the other finding). Optionally add a preflight check in the smoke script to verify the enum containsCOMPLETEDbefore attempting writes.

The multi-kind workflow foundation is well designed: schema column, registry, gate dispatch, scripts, tests, and docs are coherent. However, two issues block merge: (1) the Postgres task_status enum lacks a migration to add COMPLETED, so persisting umbrella completion will fail; and (2) checkbox mappings for COMPLETED are incomplete — reverse/forward maps weren’t updated, breaking parsing/rendering symmetry. Non-blocking nits include the relaxed typing of validateStatusTransition, heuristic classification edge cases, and minor ops/docs notes. Add the enum migration and fix the checkbox maps to unblock; with those resolved, the PR should be ready.
…weep for COMPLETED
minsky-reviewer[bot] (review 4295463959) flagged two BLOCKING issues, both
rooted in the same gap: COMPLETED was added to the TypeScript TaskStatus enum
without a matching Postgres enum-extension migration. The Drizzle schema
derives the task_status PG enum from Object.values(TaskStatus), so any attempt
to persist status='COMPLETED' would fail at the DB layer with an enum
constraint error.
The bot also surfaced three NON-BLOCKING concerns in its summary (test
invariant conflict, checkbox parsing, listing filter). Per §7 class-not-instance,
swept all sites that need to handle the new COMPLETED status.
Changes:
1. New migration 0037_add_completed_status.sql:
ALTER TYPE "public"."task_status" ADD VALUE IF NOT EXISTS 'COMPLETED'
Pattern matches 0018_add_planning_status.sql + 0019_add_ready_status.sql.
Drizzle journal updated with idx 37.
2. CHECKBOX_TO_STATUS gains 'c' / 'C' → COMPLETED entries
(taskConstants.ts) — reverse parser was missing the mapping; TASK_STATUS_CHECKBOX
already had COMPLETED → 'c' in the forward direction (prior commit).
3. VALID_TRANSITIONS test loop now excludes COMPLETED
(status-transitions.test.ts) — the "CLOSED reachable from every non-CLOSED
status" invariant was iterating all TaskStatus values including COMPLETED,
whose entry is intentionally empty (per-kind workflow handles it). Renamed
the test to clarify it covers the implementation-kind backward-compat invariant.
4. Task listing filters extended for COMPLETED — four sites swept:
- task-filters.ts: new TASK_STATUSES_HIDDEN_BY_DEFAULT tuple +
isHiddenByDefaultStatus() helper (tuple-not-Set to satisfy the
custom/no-domain-singleton ESLint rule)
- minskyTaskBackend.ts: third not(eq) clause for COMPLETED in the Drizzle query
- githubIssuesTaskBackend.ts: extended filter predicate
- backend-filtering-regression.test.ts: simulation function updated for parity
Note on the bot's NON-BLOCKING smoke-script suggestion ("extend smoke test to
write COMPLETED to DB"): the current smoke test exercises validateStatusTransition
at the logic layer (umbrella IN-PROGRESS → COMPLETED is allowed; implementation
rejects same). Adding a real DB-write probe would catch enum drift earlier;
deferred as a NON-BLOCKING follow-up — the enum migration in this commit closes
the actual drift gap.
95/95 unit tests pass.

The previously blocking enum drift has been resolved with migration 0037 adding COMPLETED to the Postgres task_status enum, and the transition gate now dispatches on kind as intended. Schema, backend logic, filters, tests, and docs coherently integrate the new kind and umbrella workflow without introducing critical regressions. One minor non-blocking nit: the legacy STATUS_TO_CHECKBOX map lacks a COMPLETED entry, though the canonical maps are correct. Overall, the fixes satisfy the spec and I find no new blocking issues — APPROVE.
Findings
- [NON-BLOCKING] src/domain/tasks/taskConstants.ts:58 —
STATUS_TO_CHECKBOXdoes not includeCOMPLETEDmapping
src/domain/tasks/taskConstants.tsaddsCOMPLETEDtoTaskStatus, updatesTASK_STATUS_CHECKBOXandCHECKBOX_TO_STATUS, but the legacy forward mapSTATUS_TO_CHECKBOX(lines ~58-70) does not include an entry forCOMPLETED. If any code still referencesSTATUS_TO_CHECKBOX["COMPLETED"], it will returnundefinedand could render an empty/incorrect checkbox. Most modern call sites useTASK_STATUS_CHECKBOX(as seen inTASK_PARSING_UTILS.replaceCheckboxStatus()andgetCheckboxFromStatus()), so this is likely benign, but for completeness and symmetry consider addingCOMPLETED: "c"or deprecatingSTATUS_TO_CHECKBOXto avoid drift.

Summary
Adds the bones of a multi-kind task workflow system: tasks gain a
kindfield, a workflow registry encodes per-kind state machines + external-tool mappings, and the state-transition gate dispatches on kind. v1 ships two kinds —implementation(current state machine, unchanged) andumbrella(new lifecycle for pure-metadata tasks that don't merge a PR).Originating incidents: mt#1768 (Cockpit bundle umbrella), and 4 metadata tasks closed earlier today (mt#1533, mt#1534, mt#1535, mt#1451) — all forced through the
CLOSEDexit because the standardREADY → IN-PROGRESS → IN-REVIEW → DONEpath requires a PR merge that pure-metadata umbrellas don't have. The cumulative count of this workaround hit 5 within ~48h, exceeding the temporary-mechanism budget perdecision-defaults.mdc §Temporary mechanism budget.Key changes

Two-kind v1 — implementation (8 states, current machine encoded as data, zero semantic change) + umbrella (5 states: TODO → PLANNING → IN-PROGRESS → COMPLETED + CLOSED). Future kinds (
bug,spike,rfc,chore,docs) are sketched in the docs as extension examples but NOT shipped in v1 — adding them is one registry entry each.Different axis from mt#455 — mt#455 (research-only, TODO) addresses task types for work-content classification (
research/design/implementation/refactor/ etc.) that map to PR-prefix derivation. mt#1812 addresses task kinds for lifecycle classification. The two should coexist as separate fields.COMPLETED state added to TaskStatus — added to the enum so the type system is exhaustive across
Record<TaskStatus, _>tables and Zod schemas. The per-kind gate enforces that only umbrella-kind tasks can transition INTO COMPLETED; implementation-kind tasks continue to use DONE. Postgres enum extended via migration 0037 (R1 fix).External-tool mapping tables — each workflow definition carries explicit
mappings.{githubIssue, linear, jira}so future migration to a real issue tracker has a concrete spec, not an ad-hoc decision.Testing
Existing task-lifecycle tests pass unchanged (implementation kind is the default, gate dispatch is byte-equivalent to the prior single state machine).
New: workflow registry tests (
workflows.test.ts, 47 tests) covering states / transitions / terminal sets / external-tool mappings per kind + getWorkflow() / isKnownKind() / DEFAULT_KIND helpers.Smoke test (
scripts/smoke-task-kinds.ts) covers 9 logic-layer checks at the gate level. The DB-write probe is deferred as a NON-BLOCKING hardening (the migration 0037 closes the actual drift gap).Execution evidence:
Plus existing tests in
status-transitions.test.tsandtask-filters.test.tscontinue to pass (verified: 95 pass / 0 fail across those three test files).Live verification
This IS a structural change — schema migration + new domain primitive. Smoke script shipped at
scripts/smoke-task-kinds.ts. Main agent will run it post-PR-merge against the live DB (which hasMINSKY_POSTGRES_URL).Concurrency analysis
The gate dispatch implements a check-then-act pattern: read task
kind, validate transition against the kind's workflow.kindfield. Race-on-kind-change between read-kind and write-status would require an operator simultaneously changing both kind AND status — vanishingly rare, and the worst outcome is a state that's still valid in both old-and-new kind's workflows (or rejected by the new kind's gate on retry).Backfill plan
Two scripts ship in this PR:
scripts/migrate-task-kinds.ts— sweeping heuristic backfill (--executeto apply); classifies all ~1800 tasks based on (hasChildren AND NOT hasPr)scripts/reclassify-umbrella-tasks.ts— surgical Phase 6 helper that flips the 6 originating umbrellas (mt#1768, mt#1451, mt#1533, mt#1534, mt#1535, mt#1143) — meant for use after merge to immediately benefit from the new kindBoth default to dry-run per CLAUDE.md
