## Rules

Every item under When not to use is a MUST NOT. MUST and SHOULD follow RFC 2119.

| Level | Rule | How it is checked |
| --- | --- | --- |
| MUST | ARIA: The badge image carries a translated alt describing the certification, never an empty alt, because the link has no other accessible name. | Not yet verified: no evidence record. WCAG 4.1.2. |
| MUST | ARIA: The link opens a PDF in a new tab and says so in its title/alt so the context change is not a surprise. | Not yet verified: no evidence record. WCAG 4.1.2. |
| MUST | ARIA: When rendered unlinked (href={null}) the alt still carries the meaning. | Not yet verified: no evidence record. WCAG 4.1.2. |
| MUST | Required stories produce no axe violations at the configured severity. | Automated by `npm run test:stories:matrix:ci`. WCAG 2.5.8. |
| MUST | The accessibility tree (role, name, state) matches the committed snapshot for every required story. | Automated by `npm run test:stories:matrix:ci`. WCAG 1.3.1, 4.1.2. |
| MUST | The component remains legible and operable under a real browser forced-colors: active pass. | Automated by `npm run test:stories:hc`. |
| MUST | Every documented keyboard interaction works as specified. | Not yet verified: no evidence record. WCAG 2.1.1, 2.1.2. |
| MUST | A human completed an end-to-end accessibility review of this component. | Not yet verified: no evidence record. |
