Stacked on #2508. Test-only.
## Why this site matters more than most
`resolveReboundTarget` answers one question: **where does a recovered
card go back to?**
Keyed on the literal `todo`, a recovered card on a renamed board is
requeued to a column that board **does not declare**. That is not
cosmetic — an undeclared column carries no trait flags, so `findColumn`
returns undefined and the card becomes invisible to every trait-driven
sweep: nothing schedules it, nothing releases it, the board does not
draw the column. **The "recovery" strands the card harder than the
failure it was recovering from.**
One of the two covered paths, `reconcileUndeclaredTaskColumns`, exists
*specifically* to repair that state — which makes it the worst possible
place for this bug to live.
## Covered, each mutation-verified independently
| site | mutation | result |
|---|---|---|
| `reconcileUndeclaredTaskColumns` | target → `"todo"` | exactly the 2
renamed cases fail |
| `autoRecoverWorktreeSessionStartFailure` | rebound → `"todo"` |
exactly the renamed requeue fails |
Neither needs git — the corrected ledger lens from #2508 (*what the
function touches*, not *what family it sits in*) made that obvious
rather than assumed.
## Both negatives included
"Re-home anything whose column looks wrong" would be a louder failure
than the strand it repairs, so: a card whose column **is** declared is
left alone, and an operator `userPaused` park is never undone.
## Fixture finding, kept in-file
`updateTask({ userPaused: true })` leaves the field `undefined` on both
`getTask` and `listTasks({slim:true})`. Seeding it that way produced a
card the sweep **correctly** saw as unpaused — a broken fixture that
would have read as a broken guard, and would have looked like a real
safety hole in the paused-park protection.
Found by probing the persisted row rather than trusting the write. Now
seeded through the integer column directly, and the test asserts the
seed took effect *before* exercising the sweep, so this cannot silently
regress into a vacuous pass.
## Verification
- three live-E2E suites green together (lifecycle, merge-family,
rebound-family)
- engine `tsc --noEmit` clean
- `pnpm test:gate` green (307 + 10 + 71)
