Revised per PR #480 review (#5590 + didericis-codex review on d8362ec):
- Remove author/committer enforcement entirely (#5590). The gate no
longer matches identity fields; author/committer are recorded as
claims in the audit store. Drop the git-gate.signing.enforce knob
(which also resolves codex issue 1: a knob that weakened the stated
guarantee). Add a "Deferred: identity enforcement" section noting it
as a possible future add. Rename PRD/file to "signed commits & audit
attribution" since identity is no longer guaranteed.
- Fix control-plane vs data-plane verification (codex issue 2, PRD 0070):
git-gate (data plane) does a synchronous pre-forward SIGNATURE check
only; the orchestrator/control plane (sole owner of bot-bottle.db)
independently re-verifies each signature before writing attributed_commit.
A gateway assertion alone never creates an audit row. New "Trust
boundary" + "Control-plane verification & recording" sections.
- Reframe the guarantee to signed provenance + host-owned, independently
verified audit record; ADR 0002 "claimed, not vouched" posture kept.
- attributed_commit now records claimed author/committer columns.
Issue: #423
