fix(tests): new CLI red from #2775 — the test pinned a decision its own PR superseded (#2801)

## New red on main

#2775 landed and put one failure on `main`, in a test that PR itself
added:

```
pr-create-review-lane-resolved.test.ts
  > refuses WITHOUT naming a phantom lane when the workflow declares no review lane
AssertionError: expected undefined to be defined
```

## Two review rounds pushed `pr.ts` in opposite directions; the test is
from the losing one

| round | decision |
|---|---|
| **1** (greptile P2) | a resolved workflow with no review-trait column
is an **answer** — do not invent `'in-review'`, say *"no review lane"*.
**This test was written against that.** |
| **2** (greptile) | refusing on an empty set rejects **every v1
workflow**, because `synthesizeDefaultColumns` upgrades a v1 graph by
emitting every column with `traits: []` — so a v1 board whose
`in-review` column plainly exists resolves to an empty review set. |

**Round 2 shipped** (`pr.ts:206-207`) and is right: an empty set is
indistinguishable from a v1 upgrade, so it means *unexpressed* rather
than *absent* and takes the same legacy fallback as an unreadable
workflow. Both rounds are extensively documented in `pr.ts` — the code
is deliberate and I have not touched it.

The consequence is simply that **there is no "no review lane" message in
the shipped code at all**, so `errors.find((e) => e.includes("no review
lane"))` returned `undefined`. The test could never have passed against
what merged.

## The fix

Re-pointed at the contract that actually shipped: the filtered board
takes the legacy `'in-review'` fallback, and the refusal must **not**
name the renamed lanes (`signoff`, `waiting-on-a-human`) that this board
no longer declares — which preserves the anti-phantom-lane intent the
test was named for.

## Flagged, not guessed

The round-1 behaviour is **not recoverable** without a way to
distinguish *"v2 board that declares no review lane"* from *"v1 board
whose traits were synthesised empty"*. The IR does not currently carry
that signal, so emitting a distinct message would re-break every pre-v2
project — the exact regression round 2 caught. Recorded in the test
rather than invented.

## Evidence

Mutations, both caught:

| mutation | result |
|---|---|
| fallback names lanes the board lacks | **1 failed** |
| the review-lane gate removed entirely | **2 failed** |

Full CLI package **1684 passed / 106 skipped (126 files)** — was 1
failed. Gate **732 green** · lint clean. Test-only; `pr.ts` restored
clean after the mutations.

## How this was found

Pre-flighting the open batch PRs against current `main` rather than
their branch heads, after batch-engine's previous landing put 32
failures on main that were only caught post-merge. #2785 and #2783 both
came back clean (commented on each); re-running `main` itself after the
newest landings surfaced this one.

#2775 review (greptile P2). My first pass fell back to `'in-review'` for BOTH the unresolvable
workflow and the resolved-but-empty case, so the refusal named a column this board does not have
— the very defect this change exists to fix, reintroduced one branch over. A resolved workflow
with no review-trait column is an ANSWER; only an unreadable workflow is a missing one.
FNXC:WorkflowLifecycleColumns 2026-07-31-03:10:
THIS TEST ASSERTED A DECISION THAT WAS SUPERSEDED BEFORE #2775 LANDED, and it went red on main
the moment it did.
Two review rounds on #2775 pushed `pr.ts` in opposite directions and the SECOND one won:
round 1 (greptile P2) — a resolved workflow with no review-trait column is an ANSWER; do not
invent `'in-review'`, say "no review lane". That is what this test
was written against.
round 2 (greptile) — refusing on an empty set rejects EVERY v1 workflow, because
`synthesizeDefaultColumns` upgrades a v1 graph by emitting every
column with `traits: []`. So a v1 board whose `in-review` column
plainly exists resolves to an empty review set.
Round 2 is decisive and is what shipped: an empty set is indistinguishable from a v1 upgrade, so
it means UNEXPRESSED rather than absent and takes the same legacy fallback as an unreadable
workflow. `pr.ts:206-207` implements exactly that. The round-1 assertion could not pass against
it — there is no "no review lane" message in the shipped code at all, so `errors.find(...)`
returned undefined.
round 3 (greptile, #2801) — round 2 over-corrected. Falling back for EVERY empty set means a
native v2 board that expresses traits and declares no review lane is
told to move its card to `'in-review'` — a column it does not have.
An impossible instruction is the defect this conversion set out to
remove, reappearing inside its own fallback.
Round 2's note claimed the distinction was "NOT recoverable ... which the IR does not currently
carry". That was wrong, and this test asserted the wrong contract because of it: the IR DOES carry
it. A v1 upgrade emits every column with `traits: []`, so NO column expresses any trait; a native
v2 board that declares traits elsewhere expresses some. `workflowExpressesAnyTrait` in `pr.ts`
separates them, and the three states now get three answers — legacy fallback for unresolvable and
for v1, an explicit refusal naming no lane for a v2 board with no review column.

THREE STATES, NOT TWO. This collapsed the last two and named a lane that cannot exist.

resolved, NO traits -> legacy id. A v1 upgrade: `synthesizeDefaultColumns` emits every
default column with `traits: []`, so `in-review` plainly exists and

resolved, traits, none -> REFUSE, and say so. A native v2 board that expresses traits and
carry review declares no review lane genuinely has nowhere to open a PR from.
Naming `'in-review'` sends the operator to a column their board does
not have — an impossible instruction, which is the defect this
conversion set out to remove, reappearing in its own fallback.
`declaresAnyLifecycleTrait` is what separates the middle case from the last; the empty set alone
cannot, which is why the first pass got it wrong in the safe direction and this one in the loud one.
