Claiming **`packages/engine/src/mission-execution-loop.ts`** (10). Every
one of its 10 census sites is the **same rule written five times**:
```ts
linkedTask.column === "done" || linkedTask.column === "archived"
```
## Census before/after
| | before | after |
|---|---:|---:|
| `mission-execution-loop.ts` | **10** | **2** |
Converted 4 of the 5 copies (8 of 10 sites) to the complete/archived
roles via core's `resolveTaskLifecycleColumns`. Each site already had
`this.taskStore` in scope inside an async method **and already had the
linked task fetched**, so the resolution rides along with a read that
was happening anyway.
## Why these converted where `store.ts`'s look-alikes could not (#2709)
Both read **another task's** column. The difference is not whose column
it is:
- **Here** — async methods, store at hand, one task per call. A
resolution is already affordable.
- **`store.ts`** — synchronous `filter` callbacks over a prefetched
`taskById` map, where per-dep resolution means N awaits inside a sync
predicate on a path that prefetches precisely to avoid per-item I/O.
Same-looking code, opposite verdicts. The distinguishing question is
**"is a resolution already affordable here"**, not "whose column is it"
— worth stating because a fleet worker pattern-matching on the receiver
alone would get both wrong.
## Not deduped, deliberately
The right shape is one predicate used five times rather than five inline
copies — and the FNXC comments above each copy show their intent has
already drifted apart. But introducing that predicate is a **new
abstraction**, which the fleet rules exclude, and it would fold five
reviewable substitutions into one design change. Flagged as the obvious
follow-up instead of smuggled in.
## Remaining: 2
The fifth copy, at the `hasLiveFixTask` site, where the terminal check
is one clause of a longer `Boolean(...)` expression whose other clauses
I would have had to reflow. Reviewability, not difficulty.
## Verification
`pnpm test:gate` **GREEN** (158 + 10 + 487 + 71) · the four mission
suites **150/150** · `pnpm lint` clean · engine `tsc` clean · `--strict`
exits 0.
