# M13-05H Status

status: done
task: script audit record integrity
updated: 2026-08-19 America/New_York
enablingTask: false
parityStateChange: false

## Scope

The production scripting audit protocol now has an independent integrity gate. Two default-deny audit
records are validated with strictly increasing ISO timestamps, contiguous sequence numbers, unique request
IDs, canonical entry digests and a continuous previous-entry hash chain. Replay, time reversal, sequence
mutation, entry digest mutation and chain mutation all return `SCRIPT_MANIFEST_INVALID`; execution remains
disabled.

## Evidence

- `npm --prefix web run test:script-audit-integrity` passed 2 unit tests and the checker.
- Checker output: `script-audit-integrity-ok entries=2 sequence=1,2 requestIds=unique time=ordered chain=true replay=SCRIPT_MANIFEST_INVALID tamper=3 execution=DISABLED next=M14-01A`.
- `git diff --check` passed.

## Next Task

`M14-01A`: freeze the current Chromium release, engine and archive hashes.

## Rollback

Remove the audit integrity checker/unit, report, manifest, package command and this status entry; restore
`M13-05G` as the queue tail.
