Nothing in the gate set read `public/*.json`. Every static gate passed and the
whole suite passed while `pnpm dev` rendered the boot-error screen instead of
the app, which is the only reason the drift survived two contract changes.
`check:dev-release-manifest` compares the fixture's `setAlgorithm`, `setDigest`
and package set against what `generate-contract-set.ts` composes, and is
registered on FE-GATE-010 next to `check-tech-log-contract` so CI executes it.
Unlike the refresh wired into contract generation, this observes the composed
set directly, so it also catches a contribution added to or removed from
`installed-contract-contributions.ts`.
`CANONICAL_GATE_SHAPE_SHA256` recomputed by hand, as always: the committed
constant 98d19911... was first reproduced from the committed `gates.json` with
an independent transcription of `canonicalGateShapeSha256`, and only then was
b4096244... hashed from the new one. Command counts move 84/96 -> 85/97;
artifacts stay at 130 because the gate publishes no evidence file, matching
`check-tech-log-contract`.
