2.

Check link image purposes. INCOMPLETE until matching source anchors can be examined; document the observable facts, counterexamples and decision gate.
3.

Deliverables

Alt text gap register. Create an evidence-linked section with observations, missing data, owner and next validation step.

Review ready text proposals. Create an evidence-linked section with observations, missing data, owner and next validation step.

Accessibility owner checklist. Create an evidence-linked section with observations, missing data, owner and next validation step.

Acceptance gate

Proposals use supplied page context and do not falsely claim WCAG compliance without independent review. Do not label this gate passed until supplied source records actually demonstrate it.

Verdict and next action

INCOMPLETE — evidence required. Request S3 and S4 from the authorized owner, reconcile them with S1 and S2, then repeat the four checks and log remaining conflicts. No production change, approval, communication, or test run is claimed.
