## What
Follow-up to the #3224 review comment *"reject legacy archived
identifiers for renamed workflows."* Test-only.
That comment had two halves. **The half it got wrong** is already
answered on main: asserting an exact single-column set `["vaulted"]`
*fails*, because `resolveProjectColumnsForRoles` unions
`LEGACY_COLUMN_IDS_BY_ROLE` in as a documented floor — so a row whose
workflow cannot be resolved still classifies. Pinning `["vaulted"]`
would encode the opposite of the design.
**The half it got right was never addressed.** `toContain` also passes
when the set grows a lane nobody intended, and an over-broad archived
set silently classifies *live* rows as archived. So the reviewer's worry
was legitimate even though the proposed fix was not.
The exact set is assertable — it just is not the one the review
proposed:
| board | resolved set |
|---|---|
| default | `["archived"]` |
| renamed | `["archived", "vaulted"]` — legacy floor + the board's own
lane |
`[...].sort()` in the helper makes ordering stable, so these pin the
resolver's whole answer rather than a substring of it.
## Proven to catch what `toContain` missed
Giving the fixture a second `archived`-trait column fails both new
assertions:
```
AssertionError: expected [ 'archived', 'cold-store' ] to deeply equal [ 'archived' ]
AssertionError: expected [ 'archived', 'cold-store', 'vaulted' ] to deeply equal [ 'archived', 'vaulted' ]
Tests 2 failed | 1 passed (3)
```
The previous `toContain` assertions pass unchanged against that same
spurious lane. That is the whole justification for this PR — without the
injection test it would be a stylistic preference.
```
clean: Tests 3 passed (3)
spurious lane: Tests 2 failed | 1 passed (3)
lint clean
```
## Note
I said in the review thread I would tighten this, so this closes that
loop. I also checked before editing whether another worker had already
done it — main already carries the FNXC tag and the legacy-floor
explanation from the same review round, so this PR adds only the part
still missing rather than redoing settled work.
