Two of the four convertible sites my own learnings doc **miscounted as sentinels** — the #2877 review corrected "8 of 9 must not be converted" to "5 of 9", and these are two of the three that correction freed. They read `task.column` straight off a row `select`, so they are board lanes by exactly the test that document gives, and a renamed archived column is simply not seen. What makes the pair worth fixing together is that they fail in **opposite directions**: | guard | on a renamed archived lane | consequence | |---|---|---| | `upsertTaskDocument` | fails to **reject** | an archived card's documents stay **writable** — the read-only contract silently does not hold | | `publishArchivedTaskDocumentAddition` | fails to **accept** | a legitimate archived-document publication is refused as `parent-not-archived` | The second is the sharper one: valid operator work refused, and refused with a message that reads as a data-integrity error rather than a lifecycle mismatch. ## Shape Both take an `AsyncDataLayer` and can resolve nothing themselves; their store-level impls hold the store, so the lane set arrives as a parameter resolved once per call — the shape #2875 used for the SQL predicate. **One shared `resolveArchivedLanes` for both paths**, deliberately: if the write guard and the publication guard could disagree about whether a card is archived, a card ends up both read-only *and* un-publishable. ## The revert proof caught my own fixture first My first version set `deletedAt` alongside the renamed column, and **the revert proof passed with the fix removed**. Both guards are `column-is-archived || deletedAt != null`, so a soft-deleted fixture short-circuits the exact comparison under test — the assertion was holding for an unrelated reason. Dropping `deletedAt` isolates it, and is also the *real* shape: a live row in a workflow-declared archived lane is what a renamed board produces, and what `getLiveTaskColumn` was written to catch. Revert proof, measured honestly the second time: restore `task.column === "archived"` and the renamed-lane case fails — the upsert resolves instead of rejecting. ## Real PostgreSQL, deliberately These are row predicates inside a transaction. A mocked store would assert the arguments and prove nothing about the comparison that runs — the same reasoning as #2875. Three cases: the renamed lane rejects, the **legacy** `archived` id still rejects (most boards never rename anything), and a live card is still allowed through (a guard that rejects everything is its own bug). ## Verification - `pnpm test:gate` — 161 / 487 / 13 / 71 passed - `pnpm lint` — clean - `tsc --noEmit` (`@fusion/core`) — clean - new `archived-document-lanes.pg.test.ts` + existing `artifacts-documents-evals.pg.test.ts` — 12 passed against real PostgreSQL Note: the SQL-literal baseline is untouched here — #2881 owns re-recording it after #2864's conversion left main's gate red. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 5 (1M context) <noreply@anthropic.com>
