# Convenient-Invention Fact Check - Chapter 12

## Changes vs Prior Canon

- New Week 5 prep card/note arrives before class and instructs partners to exchange memories before Tuesday.
- Theo's childhood drawing memory is introduced.
- June's erased-wall install memory is introduced.

## Criterion Verdicts

- New facts solve a draft problem too easily: PASS. The prep card does not rescue anyone; it creates the chapter's pressure and is consistent with Odile's anti-ambush teaching method.
- New facts contradict canon: PASS. No previous chapter stated Week 5 had no pre-class note; Odile's card system is established.
- New memories feel planted enough for future use: PASS. They are not random exposition; they directly feed Ch13 and Ch16 obligations already in the skeleton/thread ledger.
- External factual plausibility: PASS. Project-room paint-backs, primer/white coats, outlet plate removal, and small-gallery checklist language are conservative and non-plot-breaking.

## Verdict

PASS.
