# Performance Check - Chapter 18

id: performance_check | owner: codex | target: `output/chapters/chapter_18.md`

Mechanical lead: `ruleset-three-part-cadence` WATCH at line 93 (`"backs up, blank, and set"`).

- `PERFORMANCE-CLEARED — line 93` — `"She turned them over one at a time, squared the stack by feel, backs up, blank, and set the water jar..."` is a physical sequence, not keynote cadence or applause-ending rhetoric.
- `PERFORMANCE-CLEARED — no aphoristic scene close` — final line `"Wet spackle sat white beside the brighter paint"` is visual fact, not a performer stamp.
- `PERFORMANCE-CLEARED — no triadic thesis patterns` — Positive Prose removed the prior `counterweight / leaving side / answer panel` triplet.

Chapter verdict: `NO-PERFORMANCE-DRIFT`.

REVISION ORDERS: none.
