[finding] Recipe A floors the table rows only — 24 inline assertions in three now-ROSTER self-tests still register nothing on a green run

[claude]

Measured while landing #13799 batch 7b (PR #15286) on 4dd5041bd. Filed unassigned, as a finding only.

The reading

Recipe A floors a table-driven self-test at its table rows. Three of the four files in that batch also carry assertions that are not rows — written inline, one at a time, below the driving loop:

file	rows floored	assertions carrying no floor
scripts/check-agent-model-declared.mjs	18	4 (the discovery block: *.md only, a missing .claude/agents/, a directory holding no .md, real-tree discovery)
scripts/check-startup-registry-verdict.mjs	18	8 (expectRoot(...), the dead-root reverse proof)
scripts/js-comment-mask.mjs	23	12 (the interpolation view, pushed onto extra by the x(...) helper)

That is 24 assertions whose disappearance is still indistinguishable from their passing: each writes into the shared failure sink only when it FAILS, so deleting one leaves the run green and the verdict line unchanged.

Why this needs a card rather than a note

The census (node scripts/measure-self-test-floor.mjs) reads per file. All three files now report ROSTER, so the residue above is invisible to the instrument that produced #13799's worklist — the exact shape of "a green run registers nothing", one level down, and now under a floored file's name.

⚠️ Note what the fix is NOT. For js-comment-mask's extra the rows exist only because an x(...) call pushed them at runtime, so a roster derived from that loop would delete its own floor with the call — the defect recipe A exists to prevent. Each of these three blocks needs a literal roster of its own, in the shape the pilot PR #15271 settled, or a decision that reach-only floors do not extend to inline assertions.

Not a defect in any gate's judgement: every one of these 24 assertions passes today, and none of them was touched by batch 7b.

Residue note from #13799 batch 8a (PR #15308, ACCEPT 5539256020, Q1 ruled A): the red line now has two spellings across the b5 recipe — the four 8a files whose floor shares a COUNTED sink print N failure(s) (cases and floor) (the recipe's forward spelling, also recipe A's), while #15217's nine keep a plain case count on a red run. Not wrong, less precise; no back-port PR — the next b5 dispatch states the annotated spelling. Recorded here beside the 24 inline assertions so one card carries the recipe's residue.
