## What was red
A full `@fusion/core` run on `origin/main` reports **1 failed / 4700
passed**. This is that one: the SDLC funnel case in
`agent-logs-and-monitor.pg.test.ts`.
```ts
expect(result.funnel.stages.find(({ stage }) => stage === "todo")?.entered).toBe(2);
// expected 2, received 0
```
## The move is not lost
Post-U11 the default Planning column is **one** column carrying
`["intake","hold","reset-on-entry"]`. `stageForTraits` prefers the
earliest stage in flow order, so `intake` wins and a move to `todo` is
attributed to the **`triage`** stage. Analytics is working correctly;
the column vocabulary underneath it merged.
## Why not just re-point the assertion
Which stage the merged Planning column *should* report is an open
product question — I flagged it on #2669 while adding the `hold`
mapping, and it is visible to users: **the funnel shows a phantom 100%
drop between Triage and Todo on every default board since U11.**
- Re-pointing the **test** at `"triage"` quietly blesses the phantom
drop.
- Re-pointing the **mapping** retroactively changes how historical
analytics read — not a reversible call.
Neither belongs in a change whose job is clearing a red.
So the assertion now pins what is true under **either** resolution: both
moves are counted exactly once, in the single pre-implementation stage
the Planning column resolves to. When #2669 is decided, this test does
not need rewriting.
## Evidence
**6/6 passed.** Mutation-proved for the failure that actually matters:
| mutation | result |
|---|---|
| unmap every pre-implementation trait (move falls to `OTHER`) |
**fails** — `expected +0 to be 2` |
| unmap `intake` alone (attribution shifts triage → todo) | **passes, by
design** — that is the open question, not a defect |
The second row is the point of the rewrite: the test is indifferent to
the unsettled question and strict about the invariant. It still catches
a dropped, double-counted, or split move.
Gate **732 green** · lint clean. Test-only — no production file touched
(the mutations above were reverted; `git diff` clean).
## Ownership
`packages/core` belongs to the **batch-core** owner under the mega-batch
split. This is fix-forward on a red rather than a conversion, so it is
deliberately confined to one assertion in one test file and touches no
production code — it should not conflict with the batch.
