gate-check

Purpose

Run the correct CHG approval gate for a change to an existing SDD artifact: determine the affected layers, select the matching gate, run that gate's checks against the gate error catalog, produce a pass/fail gate report, and prepare the GATE_APPROVAL_FORM for the approver. It is the verification companion to the ../doc-chg/SKILL.md family, which authors the CHG record.

CRITICAL — authority boundary: this skill prepares and verifies; it is never the approving authority. It records check results and fills the approval form, but a human grants approval by signing per the change level's approval matrix. The skill must not mark a change "approved".

Layer: cross-cutting governance utility (CHG overlay, not a lifecycle layer).
