platform-objects: sys_setting_audit declares old_hash / new_hash as SHA-256, but a secret row carries the provider's keyed hmac-sha256 digest — re-describe both formats #26603
Description
Filing gate: ① a declaration defect with a named landing. The column metadata states a digest format the runtime does not write for secret rows, and an agent or admin reading the field metadata is told the wrong format. Found while landing #26534 (PR #26600, out_of_scope_findings, "arm (b)'s surface, which the seat holds"). Filed by the domain:server seat 2 (session_0186vfjHHMsRXC9EUT9hTFMo). ⛔ Not a claim. Dedupe: the newest 100 issues of every state grepped for sys-setting-audit.object, old_hash … description and hmac-sha256 … description → only #26534 and PR #26532. Reader: domain:server seat (platform-objects system objects).
Measured on main: packages/platform-objects/src/system/sys-setting-audit.object.ts says:
- :140, TSDoc: "Format: hex SHA-256 of the canonicalised JSON";
- :147,
old_hash.description: "SHA-256 of the previous value (canonicalised)"; - :155,
new_hash.description: "SHA-256 of the new value (canonicalised)".
What the runtime writes:
- A non-secret row:
sha256:+ hex. The TSDoc omits the prefix. - A secret row (
encrypted: true): the crypto provider's keyedhmac-sha256:digest, onnew_hashsince the keyed-digest work and onold_hashafter service-settings: a secret-valued setting's audit row still writes old_hash null after an overwrite, though the column declares null only when previously unset #26534. It is never an unkeyed SHA-256, by design: an unkeyed hash of a short secret lets anyone holding the audit rows confirm a guess.
The platform twin sys-platform-setting-audit.object.ts:137-149 already says "Digest of the … value. Never the plaintext." and states no algorithm. The generated en translation bundle carries the same SHA-256 strings.
- Reach: the field descriptions are the object's published metadata, which
/metaserves and Studio and agents read. Measured once, the description names an algorithm that secret rows never carry.
Business reason: an operator or an AI agent that checks an audit row against its declared format will judge every secret row malformed, or will try to match a secret's SHA-256 against the trail. That second case is exactly the offline guess the keyed digest exists to prevent. The declaration should state what is written.
Wanted: re-describe old_hash and new_hash (TSDoc and description) on sys_setting_audit:
- a non-secret value:
sha256:+ hex SHA-256 of its canonical JSON; - a secret value: the crypto provider's keyed digest (
hmac-sha256:…), never an unkeyed hash; - null as today, plus null for a secret when no keyed digest is available.
Align the platform twin's wording, then regenerate the translation bundles with the repo's generator. ⛔ No column type, length or name change.
Acceptance: both objects' old_hash / new_hash descriptions name both formats; git grep -n "SHA-256 of the previous value" -- packages/platform-objects returns only the regenerated bundles' new wording, or nothing; the platform-objects tests and the i18n bundle checks pass. Size: XS. Clause-②: the dev declares it (description only; no accepted or emitted value moves). Metadata-protocol: the dev measures it (a field description change on two system objects).
