The pre-release perf gate of the v1.74.0-beta.1 candidate reported
cache.entries.cleanFloor 120 against a ceiling of 100 (run 34480302982,
large-house-interaction-v1). The ceiling was calibrated when only the visible
space populated `_cleanFloorCache`; since #509 the summary panel computes the
clean-floor total in per-room slices through the same cache, so the sixty
fixture rooms are cached under both config epochs the interaction profile
creates — 60 × 2 = 120, exactly what the run measured.
The ceiling moves to 180 in the smoke and in the full interaction profile:
one entry per room per epoch with room for a third epoch, far below the LRU
cap of 600 and far below anything a per-frame or per-marker regression would
produce. The leak detector is untouched: cacheGrowth.cleanFloor stays 0.

The gate used to require every Validate run on the tag SHA to be green:
a cancelled duplicate or a red flake that a later re-run had fixed kept
the stable release blocked (v1.73.0, 09.09 — released by hand). Now the
verdict comes from the newest run that was not cancelled: not completed →
wait, success → pass, anything else → fail, no run → wait. The same rule
is documented for the perf workflow and the release runbook.

The #160 contract test keeps the dense profile's longTasks block equal to
the historical isometric one, and both profiles boot through the same lazy
iso-scene-render chunk; the accepted split applies to both. Validate
34356856702 caught the divergence.

Full Performance of the v1.73.0 stable candidate against the v1.72.0 product
(run 34354409872) was red on one check of the isometric profile:
longTask.countP95 16 → 20 against max(16×1.2, 16+3) = 19.2, with every
timing, longTask.totalP95Ms and longTask.maxSingleMs green. The trace behind
#506 shows why: since v1.73.0-beta.1 the isometric renderer is the lazy
iso-scene-render chunk (#160 Stage 3), so the single v1.72.0 boot task is
split in two around that import — the same work, +2 tasks.
Owner decision 2026-09-09: accept the split. countNoiseAllowance 3 → 5 for
large-house-isometric-v1 only; the ratio, the hard ceiling, total and
maximum single task keep gating real growth. The downloaded CI artefact
re-evaluated with this budget passes (limit 21, actual 20, no failures).
Documented in demo/performance/README.md; the budget test pins the
allowance and the untouched profiles.
