The **same** defect as the GitLab importer fixed in #2843, in a plugin
written from the same template — found only because I re-grepped my own
area with a wider pattern after declaring it clean.
```ts
export function buildLinearTaskCreateInput(issue: LinearIssue): TaskCreateInput {
return { title, description, column: "triage", … };
}
```
`triage` was **deleted by U11**; the default board's lanes are `todo |
in-progress | in-review | done | archived`. An explicit `column`
**overrides** the intake column `createTask` resolves for the workflow
it selects — which is precisely how the literal survived the deletion.
Nothing rejects the write and nothing logs it: the route answers with a
task id, and the card is not on the board.
Fix: omit `column`, exactly as #2843 did for GitLab.
## Two tests were pinning the bug
```ts
expect(input.column).toBe("triage"); // import-linear.test.ts
expect(createTask).toHaveBeenCalledWith(objectContaining({ column: "triage" })); // routes.test.ts
```
That is how this survived a lifecycle sweep that *did* reach the GitLab
importer. The census cannot see a lane literal passed as a **call
argument**, and the tests asserted the behaviour was intended — so both
the automated check and the human check said this file was fine.
Both now assert the column is **absent**, which is the property that
hands the decision to `createTask` and the one that fails on revert.
## The finding worth carrying forward
"We fixed the import path" was true of the forge everybody uses and
false of the other one. Two importers, one template, one of them
audited. When a defect is found in a file that had a sibling, the
sibling is the next place to look — and it is not something the census
will tell you, because this whole class is invisible to it.
## Revert proof (measured)
Restore `column: "triage"`:
```
AssertionError: expected 'triage' to be undefined
AssertionError: expected "vi.fn()" to be called with arguments: [ ObjectNotContaining{…} ]
```
## Verification
- `pnpm test:gate` — 161 / 487 / 13 / 71 passed
- `pnpm lint` — clean
- `tsc --noEmit` (`@fusion-plugin-examples/linear-import`) — clean
- full plugin suite — 35 passed across 5 files
- census `--strict` — exit 0 (unchanged: this class is invisible to it)
