## The PG gate ledger has been red since #2759
```
AssertionError: the PG gate must stay a narrow, explicit canary list
+ 'src/__tests__/postgres/sync-workflow-ir-is-always-default.pg.test.ts'
```
#2759 (`ae4ff9c111`) added that test **and** its entry in
`packages/core`'s `test:pg-gate` script in one commit, without updating
the ledger this assertion compares against.
## Recorded, not approved — and that distinction is why I touched it
carefully
My first instinct was to leave it: ratifying someone else's gate
admission is exactly the "make it green" move I have refused elsewhere
in this sweep.
What changed my mind is that **a red policy test protects nothing**.
While it fails, the *next* gate admission is invisible too — which is
the opposite of what a narrow-canary ledger exists for. The admission is
already live; the gate runs three tests today whatever this file says.
Restoring the ledger re-arms the guard for everything after it.
And the admission does carry the evidence of value AGENTS.md requires,
so recording it is not a rubber stamp. The test pins that
`resolveTaskWorkflowIrSync` returns the **default** IR for every task in
production, which means a guard written as:
```ts
resolveLifecycleColumns(store.resolveTaskWorkflowIrSync(id))?.hold
```
reads as converted, counts as census progress, and is **silently wrong
for every custom workflow** — the non-optional return type hides the
substitution from every caller. Ten call sites depend on that fact
today. Catching that class at the gate is cheaper than catching it in
review; I would have argued for admission had I been asked.
**If the gate's owner disagrees with a third canary, the fix is to
remove it from `test:pg-gate` and shorten this ledger again — not to
leave the assertion red.** I have said so in the code comment too, so
the next reader gets the choice rather than the fait accompli.
## The guard is bidirectional — verified against the gate, not the
ledger
A ledger synced to whatever the gate currently says would be worthless,
so I mutated the **gate script**:
```
removed a canary from packages/core test:pg-gate → ℹ pass 3 ℹ fail 1
restored → ℹ pass 4 ℹ fail 0
```
So it still catches silent gate **shrinkage** as well as growth — a
canary quietly dropping out of the merge gate would fail here.
`package.json` is restored; the diff is the test file only.
## One thing worth passing on
That test names a *class*, not a single bug: ten call sites resolve
lanes through the sync resolver and read as converted while always
getting the default IR. I checked where they live — **all in
`packages/core` and `packages/engine`, none in `packages/cli` or
`plugins`** — so my own territory is clear of it, but whoever owns those
two packages may want the list.
## Verification (measured)
- this suite — **4 passed / 0 failed** (was 1 failed)
- `eslint` — clean
Fourth of the red `scripts/__tests__` suites. Test-only. No changeset.
