doc-chg-fixer

Purpose

Read the latest audit report and apply fixes to a CHG record, bridging ../doc-chg-audit/SKILL.md and a gate-ready CHG so the audit↔fix cycle can converge.

CHG is NOT a lifecycle layer in the BRD..IPLAN sense: no readiness score. The fixer drives the record to gate_ready: true (audit PASS); the actual approval is a human decision via ../gate-check/SKILL.md, never auto-granted here. For team-mode dispatch purposes the CHG layer is addressed as 09_CHG (the layer-id slot occupied by the change-management overlay).

Scope: a CHG can touch any artifact along BRD → PRD → EARS → BDD → ADR → SPEC → TDD → IPLAN → Code. Upstream: the CHG record + .aidoc/audit/09_CHG-audit.md. Downstream: the fixed CHG + CHG-NN.F_fix_report_vNNN.md.
