catalog.py was 251 lines. Its five defensive accessors for the loosely-typed /wsg/ JSON -- _get, _as_list, _as_int, _as_md5 and the _MD5_SHAPE / int64 range constants they depend on -- form a cohesive unit distinct from the parsing logic above them, so they move to a sibling _coerce.py and become module-public there. No caller or test referenced the private helpers (downloader.py uses only the six public parse functions), so no re-export shim was needed and the public API is byte-for-byte unchanged. catalog.py 251 -> 175, new _coerce.py 87. Both modules stay at 100% branch coverage; 277 wsg_grabber tests pass.
