The allowlist added in the previous commit keyed the reviewed
sheet.range_set_style migration by bare RPC name ("update_range"), but
interface_ref holds the canonicalized JSON that parseTool produces via
canonicalRawJSON. The lookup therefore never matched, the carve-out was
effectively disabled, and the real gate failed with
`schema tool "sheet/sheet.range_set_style" changed interface_ref`.
The existing redirect test did not catch this: it registered the fixture entry
using its own value and then asserted with the same value, so any format would
have passed. That is the same mistake as keying a probe on the author's field
spelling instead of the wire contract.
- The allowlist entry now uses the compact canonical JSON, taken from the gate's
own output rather than from pretty-printed `dws schema`.
- TestCrossPlatformCoverageReviewedRedirectKeysAreCanonicalJSON recomputes every
registered key through canonicalRawJSON, so a bare name or a pretty-printed
variant fails locally instead of only in CI.
sheet export keeps its reviewed mcp + submit_export_job declaration. The comment
now records the known trade-off explicitly: --export-format csv is a mutually
exclusive branch that reads get_range_as_csv and never invokes the declared
submit_export_job, so this declaration does not cover the csv branch's backing
interface. Attributing that branch is left out of scope for this change.
Verified against the real gate, not just unit tests: all four Interface
Integrity checks pass (authoritative-interface-integrity,
check-command-compatibility, schema-compatibility, skill-command-integrity).
