I reviewed only the ten requested checksum/API/auth/docs files. I did not treat inherited dependency-security source as this PR’s ownership. I found one finding.

The generated component slice duplicates canonical owners #1418 (URL/contact hygiene) and #1361 (content checksum) while weakening their fail-closed bounds and evidence contracts. Preserve this branch history but return the effective tree to protected develop so no competing implementation can merge from this lane.

Refs #1247. This PR implements only the normal-surface

MD5, SHA-1, aliases/case variants, and unknown names are rejected. The tool preserves exact bytes without Unicode normalization, enforces a 1 MiB UTF-8 byte ceiling, and states that an unkeyed digest does not authenticate a sender or replace a MAC/signature.Current authority — 2026-09-10

No force push, destructive rebase, dependency source copy, synthetic status, or gate weakening was used. Fresh compare proves the resulting effective diff is still only the ten checksum/API/auth/docs files.RED → causal fix: invalid UTF-8 scalar input
Fresh validation of the last substantive CodeRabbit finding proved it was real:
content_checksum_handler()calledtext.encode("utf-8")directly, so JSON-decoded lone-surrogate text could raise rawUnicodeEncodeErrorand bypass the deterministic tool-error contract.90988f660fb5b26d5169311ddf1b39d33185775f228553ba730ab88d66723a5f8b2a6a7cd6694c21dc480c3bc2294d351eef5fdaa61cbf80e0429b19The direct regression requires
ContentChecksumError.error_code == "content_checksum_invalid_utf8". The authenticated API regression sends escaped\ud800so the server JSON decoder materializes the invalid scalar before tool execution; the failure envelope must expose the same stable code.
