Instruments a surface no existing check can see. Follows #2839, and
**corrects the count I reported there** (12 → 14).
## Why it was invisible
The lifecycle census parses TypeScript **comparisons**; a legacy id
inside a SQL string is string data. The inert-seam gate reasons about
parameters and call sites. Neither has ever looked here.
**What it cost:** `cleanupStaleMergeQueueRowsImpl` filtered on `t.column
!= 'in-review'`, so on a renamed board every queued card looked stale,
its `merge_queue` row was deleted, and the card became **unleaseable**.
The operator found it reviewing #2819 — in SQL I had already read past
during that same work.
The quieter half is analytics: five sites count `"column" = 'done'`, so
throughput, cycle time, and team dashboards report **zero completed
work** on a renamed board. Nothing errors, which is why nobody files it.
## What this does, and does not do
It does **not** fix the sites. `resolveProjectColumnsForRoles` is the
mechanism and its migration has an owner (#2839). This freezes the
population so the surface cannot grow underneath that migration: a new
file or a higher count fails, **and a lower count fails too** — so the
baseline ratchets down as sites migrate rather than leaving slots to
silently regrow into. That is the same rot as an allow-list entry for a
deleted function, which this repo already hit once.
AST-based, deliberately: a line grep for the same pattern reports **37**
hits, **25 of them prose** quoting `column === "done"` in explanatory
notes. A guard that is 68% false positives trains its readers to skip it
— a lesson this program has already paid for.
## Two corrections found by mutation-testing my own gate
**1. Clause fragments were missed.** Requiring a SQL keyword *in the
same literal* skipped `team-analytics.ts`, which builds
`["assignedAgentId IS NOT NULL", `"column" = 'done'`, ...]` and joins
them into a `WHERE` later. That fragment is as vocabulary-bound as any
full query but contains no keyword. Fixing it took the population **12 →
14**, so the number I put on #2839 was low.
**2. My first mutation test proved a direction it had not.** I replaced
the first textual occurrence in a file — which was inside a **comment**
— and read the unchanged count as the scanner being broken. The scanner
was right; my test was wrong. All three directions are now driven
against real SQL:
| mutation | result |
|---|---|
| add a full query with a legacy comparison | `3 SQL column literal(s),
baseline allows 2` |
| add a bare clause **fragment** (no keyword) | caught — same failure |
| migrate one away (count drops) | `1 site(s) now, baseline still allows
2 — re-record it` |
| restore | exit 0 |
I am flagging that second one because it is the exact failure mode this
program keeps finding: a green result read as evidence when the
experiment was invalid.
## Verification
`pnpm test:gate` green with the new check in it · lint 0 · single AST
pass. Wired into `test:gate` and both `pretest` hooks.

## Summary by CodeRabbit
* **Bug Fixes**
* Added automated checks to detect increases in legacy SQL column
literals.
* Added baseline tracking to ensure known SQL literal counts do not
regress.
* **Tests**
* Expanded pre-test and gated verification steps with SQL literal and
mock completeness checks.
* Updated test validation workflows to enforce the new safeguards.
