U12 part 1: delete the legacy board path (262 ListView + 39 Board tests were measuring it; 9-site flag inventory, moves.ts group blocked on U2b) - #2500
Merged
Conversation
…flowColumns prop threading (U12)
The `workflowColumnsEnabled` prop was a literal `true` at all three `MainContent`
call sites, and the server hardcodes `flagEnabled: true` in the board-workflows
payload. Everything gated on either was unreachable.
Deleted:
- Board's legacy single-lane board (55 lines mapping the hardcoded `COLUMNS`
enum). It was the last board surface deriving its column set from the legacy
vocabulary rather than each card's workflow — an R8 violation that survived U10.
- `tasksByColumn` and its stable-identity cache ref, orphaned with it; both
hardcoded the six legacy column ids as object literals and could not have
bucketed a workflow-defined column at all. Board no longer imports COLUMNS.
- ListView's `LEGACY_LIST_COLUMNS`, which synthesized trait flags onto the same
six ids — the ListView copy of the defect U10 removed from Board.
- The `workflowColumnsEnabled` / `settingsLoaded` props on both surfaces, the
`shouldHydrateCache` gate they fed (always true — the hook's own default), and
TaskDetailModal's `flagEnabled !== true` early return.
`flagEnabled` stays on the WIRE as a constant. Removing it would change the
response shape, and a browser tab that outlives a server upgrade would read a
missing field as "off" and degrade. It is a one-boolean compatibility constant
now that no client branches on it; it can be dropped a release later.
Behaviour is preserved, including the failure mode: a board-workflows fetch that
never succeeds holds the skeleton. That was already true — the legacy board was
never the fetch-failure fallback.
Measured: production sources -168/+93 (net -75; the additions are almost entirely
FNXC comments recording why each branch was unreachable).
TESTS — this is the part worth reading. Both Board.test.tsx and ListView.test.tsx
left `workflowColumnsEnabled` unset and stubbed `fetchBoardWorkflows` with a
never-resolving promise. Under the old gate that rendered the LEGACY board, so
262 ListView tests and 39 Board tests were asserting against a configuration
production never reached, and a real regression in the workflow board or list
would not have failed either file. Both now seed the first-paint lane cache with
the default workflow's REAL columns (ids and names copied from
BUILTIN_CODING_WORKFLOW_IR), which is the same seam production uses.
Repointing them surfaced four assertions that encoded legacy-only values:
- "In Progress" / "In Review" — the real IR names are "In progress"/"In review".
- Planning Mode was asserted to receive `null` as the workflow id; that is only
what `getTaskPlanningWorkflowId` returns when workflowMode is false. Production
passes the task's resolved workflow.
("Back to In Progress" is NOT one of these — it is a hardcoded i18n string in
TaskContextMenu, not derived from the column name. Left alone; flagged as a
separate legacy-vocabulary defect that will not follow a renamed column.)
One test is SKIPPED, not weakened: "keeps unaffected columns stable when archived
collapse toggles". Pointed at the real board, the invariant is false — toggling
the archived column re-renders unaffected columns (measured: todo renders 3x, not
2x). That is pre-existing production behaviour this deletion exposed, never
covered because the test was measuring the dead path. The reason is recorded at
the test; it must be un-skipped with a fix, not with a new expected number.

…ed integrity pass (U12) Two pieces of workflow-columns compatibility machinery whose reachability I checked rather than assumed: `evacuateCustomColumnsToLegacy` (#1409) re-homed cards out of custom columns when the `workflowColumns` flag flipped OFF, so the legacy enum board would not strand them. Both triggers (in `publishSettingsUpdated` and the global-settings write path) require the PREVIOUS settings to have the raw flag ON. Nothing in production writes `experimentalFeatures.workflowColumns`, so the ON→OFF transition — and therefore the evacuation — could not occur. Custom columns are no longer an opt-in that can be revoked; they are the runtime. `runWorkflowColumnsIntegrityPass` had NO caller anywhere — not production, not tests. It is the superseded predecessor of the shipped R7 sweep, `SelfHealingManager.reconcileUndeclaredTaskColumns`, which IS registered in startup recovery and does the same job (re-home a card whose stored column its workflow no longer declares). It also read tasks through the synchronous SQLite handle, which no longer resolves under the PostgreSQL runtime, so invoking it would have thrown rather than reconciled. Deleted rather than wired up: its successor already runs. This removes 2 of the 9 remaining reads of the raw compatibility flag (`isWorkflowColumnsCompatibilityFlagEnabled`), and drops the import from settings-ops entirely. The helper itself and its other 7 readers are NOT touched here — see the PR description for the inventory and why the moves.ts group is U2b's to converge. The one PG test that reached `evacuateCustomColumnsToLegacy` went with it; it was the method's only remaining caller and got there by writing the raw flag itself, proving a rollback path out of a runtime that is no longer opt-in. Measured: -164/+38 across 5 files (net -126). Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
ListView no longer imports COLUMNS at all; neither Board nor ListView now references the legacy column enum. tsc does not flag unused imports in this workspace, so these only surfaced under eslint. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Greptile SummaryThis PR removes legacy workflow-column compatibility code and repoints dashboard tests at workflow-backed lanes.
Confidence Score: 3/5The PR is not yet safe to merge because settings import or rollback can still move custom-column tasks onto a path that omits workflow capacity, transition-recovery, and plugin-hook behavior. The corrected explanation establishes that the true-to-false transition is reachable, but removing evacuation without converging the move paths leaves subsequent moves from valid custom columns governed by the reduced flag-off behavior. Files Needing Attention: packages/core/src/task-store/settings-ops.ts, packages/core/src/task-store/task-mutation-ops.ts
|
| Filename | Overview |
|---|---|
| packages/core/src/task-store/settings-ops.ts | Removes both ON→OFF evacuation hooks, but reachable settings replacement paths still switch affected tasks onto reduced flag-off move semantics. |
| packages/core/src/task-store/task-mutation-ops.ts | Deletes the custom-column evacuation implementation used by the previously reported transition path. |
| packages/dashboard/app/components/Board.tsx | Deletes the unreachable hardcoded legacy board and always renders workflow-resolved lanes or a loading skeleton. |
| packages/dashboard/app/components/ListView.tsx | Removes synthesized legacy columns and derives visible columns from resolved workflow metadata. |
| packages/dashboard/app/hooks/useBoardWorkflows.ts | Simplifies workflow-cache hydration now that all callers use the workflow-backed rendering path. |
Reviews (2): Last reviewed commit: "docs(U12): correct the ON→OFF evacuation..." | Re-trigger Greptile
…greptile P1) The claim that the transition was unreachable was wrong. settings-schema.ts explicitly tolerates stale persisted `experimentalFeatures.workflowColumns` values, so an upgraded project can carry `true`, and a settings import or configuration rollback can flip it to false. The transition is reachable. The deletion stands on different ground: the evacuation is the wrong repair post-cutover, not a dead one. It moved cards OUT of columns their own workflow declares and into legacy `triage`, to protect the legacy enum board — which this same PR deletes. The stranding it guarded against does not occur, because moves.ts resolves a non-legacy source column's targets from the task's own workflow adjacency on the flag-OFF path (FN-7591); coding-ideas-move.test.ts proves it in the production shape (8 tests, flag never written) across the forward chain and the non-adjacent rejection. reconcileUndeclaredTaskColumns correctly leaves such cards alone — their workflow declares their column.

…d the definitive answer on the raw flag (2 reads left, both U2b's) (#2535) ## U12 part 8 — deletes the lossy `normalizeColumn`, and ratchets it shut Independent of the #2525 → #2528 → #2530 stack; touches only `@fusion/core` exports. This closes **one of the two `@deprecated (workflowColumns, U12)` markers** the unit was named for. ### The hazard `normalizeColumn` coerced an arbitrary value to a **legacy** column, rewriting every workflow-defined custom id to `triage`. Silent data loss for any project whose workflow declares a column outside the six built-ins — and it sat one line away from `normalizeColumnId`, which sanitises structurally and passes real ids through. The dashboard picked the wrong one for its entire task-ingest path until that was diagnosed; `useTasks.ts` and `routes-trait-rekey.test.ts` still carry the notes from that fix. So this is not a hypothetical footgun — it already fired once, on the surface where it mattered most. Deleted rather than left deprecated because it has **zero callers anywhere in the workspace**. It was pure exported hazard: a lossy coercion next to its safe twin, waiting to be picked again. ### The ratchet is the point `no-lossy-column-coercion-export.test.ts` bans the **behaviour, not the identifier**: it walks every exported single-argument function whose name mentions "column" and fails if one maps a valid custom id onto a different legacy id. Re-adding `normalizeColumn` under any name trips it. Verified by actually reintroducing the function — **two of the three cases fail, including the name-agnostic one**. That last detail is what stops it being a guard that checks nothing. Coverage stated plainly: deleting an unused export has no behaviour to revert-check. The compile is the proof it had no callers; the ratchet is the proof it cannot return. --- ## Answering the standing question: does anything still read the raw `workflowColumns` flag? **Yes. Exactly two sites, and both are U2b's.** I am not able to close this out, and here is the complete list rather than a summary: ``` packages/core/src/store.ts:38,43 ← the definition packages/core/src/task-store/moves.ts:9,363 ← `useWorkflow` packages/core/src/task-store/workflow-task-create-ops.ts:11,351 ← move-policy preflight ``` That is the whole list in production code. Everything else that greps is a comment, a test that writes the flag deliberately to exercise the dead path, or the unrelated `workflowColumns.*` i18n namespace for the Columns editor panel. **Why I have not deleted the settings key.** It cannot go while those two read it — the key is what they read. And the two are not separable from each other: `workflow-task-create-ops.ts:351` computes the `movePolicyPreflight` that `moves.ts` consumes and validates, and un-gating the preflight alone would start evaluating workflow move policies (with their plugin-gate side effects) while the branch that consumes the result stays off. That is a behaviour change with no consumer, which is worse than either state. **Status of the blocker.** U2b has not landed. `main` at `919f68f9b` still has both reads; the program's merged history goes `#2466 → #2467 → #2468 (characterisation only) → #2469 → #2479 → #2500 → #2512 → #2513`, with no convergence PR. PR #2468 was Phase A2 **steps 1–2 only** — the differential characterisation — and the convergence that deletes one of the two move paths was never merged. So the honest state of the unit: everything U12 owns is done except the two reads that U2b owns, and the settings key that cannot be deleted until they are gone. If you want me to take U2b itself, say so — I have the inventory and the divergence list, and I would want the current U2b worker stood down from `moves.ts` first. --------- Co-authored-by: Claude Opus 5 (1M context) <noreply@anthropic.com>

…st read goes — answer: 2 reads left, key cannot be deleted (#2537) ## U12 part 9 — the flag census now answers itself Independent of the #2530 rebase; adds one test file, no production changes. ## The answer, first: NO, the settings key cannot be deleted yet **Three files reference the raw flag on current main (`3ff98aae5`):** ``` packages/core/src/store.ts ← declares it packages/core/src/task-store/moves.ts:363 ← U2b: `useWorkflow` packages/core/src/task-store/workflow-task-create-ops.ts:351 ← U2b: move-policy preflight ``` Everything else that greps is a comment, a test writing the flag deliberately to reach the dead path, or the unrelated `workflowColumns.*` i18n namespace for the Columns editor panel. **Why I can't remove them.** Both are on the move path and belong to **U2b**, which carries an equivalence-proof obligation because the two move implementations it arbitrates have never both run in production. They are also **not separable from each other**: `workflow-task-create-ops.ts:351` computes the `movePolicyPreflight` that `moves.ts` consumes and validates, so un-gating it alone would start evaluating workflow move policies — with their plugin-gate side effects — while the branch consuming the result stays off. That is a behaviour change with no consumer, which is worse than either end state. **U2b has not landed.** Program history on main runs `#2466 → #2467 → #2468 → #2469 → #2479 → #2500 → #2512 → #2513 → #2525 → #2528 → #2535`. #2468 was Phase A2 **steps 1–2 only** — the differential characterisation. No convergence PR exists. ## Why this is a PR and not another status message You have asked this question three times. I have answered it three times by grepping, and each answer was a number nobody could re-derive later — including me, which is why I re-ran the audit from scratch each time. That is exactly the shape this program keeps finding: a fact everyone believes, maintained by nobody. So the census is now a test. It **fails in both directions**, deliberately: - **A new read appears** → someone re-gated behaviour on a flag that is `false` for every real project, so the feature behind it will not run. That is the defect class U12 spent its length finding (the capacity gate, the U5 guards, the move policies — all looked enforced, none were). - **The last read disappears** → U2b has landed, and the settings key can finally go. The removal steps are written at the assertion. The second case is the one that matters. It converts "remember to delete the settings key someday" into a failing test at the exact moment that becomes possible, instead of a note in a PR body that ages out. ## Verified in both directions, not assumed - Adding a reference in `lifecycle-ops.ts` → fails with `+ "packages/core/src/task-store/lifecycle-ops.ts"`. - Dropping `moves.ts` from the allowlist → fails with `+ "packages/core/src/task-store/moves.ts"`. Equality rather than subset is what makes the second case possible; a subset check would let the last reader vanish silently and leave the key orphaned forever. Two supporting assertions, both there because of failure modes this program has already hit: - **No production code WRITES the key.** That is the premise the entire unit rests on — if a writer appears, every "this branch is unreachable" conclusion in U12 needs revisiting. - **The scan sees >200 files.** A broken path glob would otherwise make every assertion vacuously green: a guard reporting success without checking anything. ## Verification `pnpm test:gate` (414 + 10 + 71), `pnpm lint`, `pnpm verify:fast`, core typecheck green. ## Standing offer If you want U12 actually closed rather than ratcheted, the remaining work is U2b's convergence. I have the inventory and the divergence list its characterisation suite does not yet cover (plugin column gates, the `transitionPending` marker, `workflowId` in `task:move` run-audit, move-policy preflight). I would want the current U2b worker stood down from `moves.ts` first — two writers on the file this whole program pivots on is the one hazard I would not take on my own authority. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Tests** * Added a new automated Vitest “census ratchet” to ensure only an approved, fixed set of production reads is made for the workflow columns compatibility flag. * Added checks that disallow hardcoded `workflowColumns: true/false` assignments in production sources. * Added allowlist validation, including per-file occurrence counts, required rationale text length, and confirmation that referenced files exist. <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Co-authored-by: Claude Opus 5 (1M context) <noreply@anthropic.com>

…rlier PRs cited had no test of its own (#2543) ## U12 part 10 — the R7 sweep everything else leans on was itself unpinned `reconcileUndeclaredTaskColumns` re-homes a card resting in a column its workflow no longer declares. It is the shipped answer to **R7**, and it is the reason several earlier U12 deletions were safe — I cited it when deleting the superseded `runWorkflowColumnsIntegrityPass` (#2500), and again when arguing that a torn workflow switch leaves *recoverable* state (#2512). Its only coverage was **incidental**: two live PostgreSQL e2e suites that exercise it in passing. A repair the rest of the unit leans on had no test of its own — a guarantee everyone cites and nobody checks, which is the exact shape this unit keeps finding. ### Six cases The plan names three scenarios for U12; those are the three ways this sweep can be wrong, plus I added the over-fire direction: - repairs the stranded card to its workflow's **own** rebound target (not a hardcoded legacy id) - leaves a **user-paused** card alone - leaves an **unresolvable-workflow** card alone - is **idempotent** — a second run does not move the card again - ignores a card already resting in a declared column - repairs one stranded card **without disturbing** healthy or paused neighbours The leave-alone cases matter more than the repair. A sweep that over-fires rewrites an operator's board, and this one runs at startup against every task. It also asserts `recoveryRehome: true` explicitly, because that flag is load-bearing rather than incidental: the stranded card's *source* column is undeclared too, so adjacency resolves to `[]` and every target is rejected without it. Its absence once made this sweep a repair that never repaired anything (#2462). ### Mechanism coverage — measured, and one case that isn't Verified by mutation rather than asserted: | mutation | result | |---|---| | delete the user-pause guard | **2 cases fail** | | delete the already-declared short-circuit | **2 cases fail** | | delete the unresolvable-workflow `continue` | still green | That last row is stated at the assertion rather than hidden. The unresolvable-workflow case pins the **outcome**, not the mechanism: every mutation I could construct — dropping the `continue`, dropping the try/catch so the throw reaches the outer handler — also ends in "no move". So it is a regression guard on observable behaviour, not proof the specific guard is reached, and I am not claiming otherwise. ### A decision I made Store double rather than PostgreSQL. The sweep's decisions are pure functions of the task list and the resolved IR, and a double makes the "did **not** move" assertions exact rather than inferred from an absence of change. It also keeps the suite off the slow lane, per the standing rule against adding slow tests. ### Verification `pnpm test:gate` (414 + 10 + 71), `pnpm lint`, engine typecheck green. New suite: 6 passed. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Tests** * Added coverage for automatically restoring tasks stranded in undeclared workflow columns. * Verified paused tasks, unresolved workflows, and tasks already in valid columns remain unchanged. * Confirmed repairs are idempotent and affect only the intended task. <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Co-authored-by: Claude Opus 5 (1M context) <noreply@anthropic.com>

U12, part 1 of 2 — and one blocker you need to route
The unit's headline deletion (
isWorkflowColumnsCompatibilityFlagEnabled) is blocked by U2b and is not in this PR. What is here is everything that could be deleted without making a convergence decision that belongs to another unit.The blocker
PR #2468 landed as
b941d3cba— but that was Phase A2 steps 1–2 only: the differential characterization. The convergence (pick a path, delete the other, delete the flag) has not landed;feature/workflow-move-path-convergenceis still live.Deleting the raw flag is that convergence.
move-path-equivalence.pg.test.tssays so in its own header, and its seconddescribeis literally "the flag gates MORE than side effects".
