# Interchangeability Test - Chapter 06

- CHARACTER-SPECIFIC - `route card sat in his chest pocket` (Theo) - would break if reassigned because Theo's voice card owns keys/labels/schedule/logistics.
- CHARACTER-SPECIFIC - `wearing Mara's black scarf` (June/Mara object) - would break if reassigned because S-SCARF-01 is June/Mara rupture object.
- CHARACTER-SPECIFIC - `I was going to start at the front` (June) - would break if reassigned because it is compact agency and visual process.
- CHARACTER-SPECIFIC - `Rent math is not a proposal` (Ben/Priya) - would break if reassigned because their arc is move-in/rent practicality.
- CHARACTER-SPECIFIC - `The floor slopes. The painting's level.` (Luis) - would break if reassigned because Luis owns sightline/material verdicts.
- CHARACTER-SPECIFIC - `Stand here. Not symbolically` (Sam) - would break if reassigned because Sam owns making literal room.
- CHARACTER-SPECIFIC - `who can she tell who isn't you?` (Ruth) - would break if reassigned because Ruth owns privacy/cover distinctions.
- CHARACTER-SPECIFIC - chapter ending `his thumb found the empty place on his shirt where the route card had been` (Theo) - would break if reassigned because only Theo has the route-card/control motif.

Closest calls: `The route card seemed less necessary for a dangerous instant` could be a generic interior image, but the route card is Theo-owned; `He checked the pocket with the route card... gallery keys` is a body action but keyed to Theo's job/control; `The back was blank` is emblematic but tied to the literal card.

Chapter verdict: DISTINCT.

REVISION ORDERS: none.
