test(floors, spec): the tombstoned-row-status liveness floor equals today's measured population (40), so retiring one tombstone reds it — floor at about two thirds #26541
Description
Filing gate: ④ the per-lane child of coordination parent #26444. Its triage line on #26523 (comment 6435758756) says, verbatim: "The packages/spec/scripts/liveness site the body names is domain:spec's. It is a separate Part of #26444 child, filed on claim, ⛔ not edited here." Filed by the domain:server seat 2 (session_0186vfjHHMsRXC9EUT9hTFMo) on claiming #26523 (claim 6436024957). ⛔ Not a claim. Dedupe: the newest 100 issues of every state grepped for tombstoned-row-status → only #26523 and #26444. Business reason: inherited from #26444, maintainer 「同意」 to the director's check-retirement sweep, 2026-10-27. Reader: domain:spec.
Part of #26444.
Measured on main: packages/spec/scripts/liveness/tombstoned-row-status.test.ts declares const TOMBSTONE_FLOOR = 40; ("the population measured on the commit that pinned this — the non-vacuity floor"). #26444 measured the tombstone population at 40, so the floor equals today's count. Retiring one tombstoned key, which is ADR-0087's normal end of a transition window, reds this test even though nothing is wrong.
Wanted: the parent's rule. Move the floor to about two thirds of the re-measured population, rounded down (the vite-dts-wiring-ratchet precedent: measured 22, floor 15). Put a one-line comment beside it naming the measured value and the date. ⛔ Not weakened: the PR shows the test still reds when the population is emptied.
Acceptance: dropping one tombstoned key from the population reds nothing, the floor sits below the measured value by a margin stated in the PR body, and the spec liveness tests pass. Size: XS. Clause-②: no. Metadata-protocol: none.

packages/spec/scripts/liveness/tombstoned-row-status.test.ts; rationale: p2 ·domain:spec· part of test(floors): floors set at today's measured value and two-sided baselines red on every legitimate deletion — ui package counts in ~8 places, CLI command counts, catalog entries pinned 4×, slot-lookup-class baselines that fail on a decrease #26444. Set the floor to about two thirds of the measured population (40), per the parent's rule, so retiring one tombstone stays green and a collapse still reds. ⛔ It keeps the non-vacuity purpose stated in its comment.Generated by Claude Code
