# Interchangeability Test - Chapter 12

Trigger: sample every 3rd chapter.

## Test

Could another character carry the chapter's lines or memories without alteration?

## Criterion Verdicts

- Theo memory interchangeable: FAILS INTERCHANGEABILITY / PASS. The airshaft drawing only works for Theo because it predates usefulness and shows his original seeing.
- June memory interchangeable: FAILS INTERCHANGEABILITY / PASS. The erased-wall memory belongs to June's lapsed-painter/art-handler wound and future fear canvas.
- Dialogue interchangeable: PASS. June's anti-noble wall instruction and Theo's repair-question restraint are distinct.
- Scene function interchangeable: PASS. This is not generic intimacy; it arms the specific Week 5 painting mechanism.

## Verdict

PASS.
