# Interchangeability Test - Chapter 15

id: interchangeability_test | owner: codex | target: `output/chapters/chapter_15.md`

- `CHARACTER-SPECIFIC — "Her handwriting had gotten neat, which it did when nothing else was." (June) — would break if reassigned because June's stress response is sorting/precision; Theo would list tasks, Asha would text rates, Nia would set deadlines.`
- `CHARACTER-SPECIFIC — "The math was doing itself in the margin anyway..." (June) — grounded in June's notebook/offer evaluation and self-protective competence.`
- `CHARACTER-SPECIFIC — "The line that interested her was true up the Vandercook. Not the wall. The press." (June) — would break if reassigned because it exposes June's lapsed-painter/art-handler wound.`
- `CHARACTER-SPECIFIC — "She could see the back room at eight-fifteen... the wall a clean field..." (June) — painter/installer optical interior image.`
- `CHARACTER-SPECIFIC — "The version that kept returning put her at the press with a rag..." (June) — image grows from June's established tendency to make rooms usable.`
- `CHARACTER-SPECIFIC — "Asha... would walk into the Tasker building and have the gripper bar apologizing by Friday..." (June on Asha) — June's appraisal of Asha is work-competence specific and serves the later referral.`
- `CHARACTER-SPECIFIC — "Coats are people who left their position marked." (June text) — would break in Nia/Asha/Priya because it belongs to June/Theo's `After Class` label-note register and install vocabulary.`
- `CHARACTER-SPECIFIC — "She checked the jacket cuff—the umber had gone fully matte..." (June) — painterly surface/color perception; not interchangeable with Nia's institutional register.`
- `CHARACTER-SPECIFIC — chapter ending: "left the deadline pinned under the jar she hadn't opened" (June) — closing move binds June's object-sorting stress response, Ch14 mineral-spirits care move, and the offer deadline.`

Closest-to-interchangeable elements:
- `"Her phone buzzed against the table."` is functional blocking and could belong to anyone, but it is incidental, not a tell/metaphor/ending.
- `"A chair creaked on her end."` is a phone-call grounding beat, not a character tell.
- `"Fifteen days."` could be a generic countdown if isolated, but the surrounding receipt/jar/catalog stack makes it June-specific.

Chapter verdict: `DISTINCT`

REVISION ORDERS: none.
