The namespace REST contracts PR (#5745) added 7 new s3_error! invocations in
read_bounded_json_body, pushing the s3s footprint counter from 1687 to 1693
and violating the ratchet baseline.
Replace those calls with ApiError::invalid_request() (gateway-side error
abstraction, rustfs/backlog#1677 F1, rustfs/backlog#1733) and lower the
baseline from 1687 to 1686.
- Add ApiError::invalid_request(message) constructor to rustfs/src/error.rs
- Replace 7 s3_error! calls in read_bounded_json_body with S3Error::from(ApiError)
- Lower S3_ERROR_LINES_BASELINE from 1687 to 1686
Verification:
- make pre-commit: all guard scripts + fmt-check + quick-check passed
- make clippy-check: passed
- cargo test table_catalog + admin handler tests: 406/406 passed
- s3s-e2e: 27/27 passed
Freeze the direct s3s dependency surface with a lower-only ratchet so it
cannot grow while the s3gate/gateway migration shrinks it
(rustfs/backlog#1677 review finding F1; acceptance criteria in
rustfs/backlog#1733). Baselines verified on 2026-08-05: 236 files
importing s3s, 1686 s3_error! invocation lines. Wired into make
pre-commit / pre-pr / dev-check and the Quick Checks job in ci.yml and
its ci-docs-only.yml mirror.
