`test_vault_kv2_sources_do_not_claim_transit_wrapping` asserted that four
`include_str!`-pinned files never describe the Vault KV2 backend as wrapping key
material through Vault's Transit engine. The invariant is a documentation-claim
invariant with no behavioral twin by construction, and the test form was weak in
both directions: it saw only four files (the same prose in a fifth file passed
silently) and it stopped compiling — rather than reporting a violation — as soon
as one of them was renamed.
Move the four literals verbatim into `scripts/check_fips_wording.sh`, which
already guards the adjacent cryptographic over-claim class (unsupported FIPS
validation wording) and is anchored to the same policy document. The guard now
greps every file under `crates/kms` for the same four case-sensitive literals and
separately reports a moved pinned source instead of failing to build.
`check_fips_wording.sh` previously ran only in `make pre-commit` / `pre-pr`, so
wire it into the Quick Checks job of both CI workflows to keep the invariant's
failure visibility at least as strong as the deleted test's.
