 * Item 8 (manifest-parser half of #3176): a lane's selection manifest prints
 * framework route paths (`app/(shop)/[id]/page.test.ts`, `@modal`, `$id`)
 * and the parser keeps them whole. Cutting them down to `page.test.ts`
 * dropped the test from its platform lane, so its remote receipt obligation
 * vanished and the test ran locally instead.
