## 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: Each share control is labelled (aria-label): Share on X/LinkedIn/Facebook and Copy link. | Not yet verified: no evidence record. WCAG 4.1.2. |
| MUST | ARIA: Icons are aria-hidden; the copy button's aria-label switches to "Link copied!" on success, and the confirmation text is written into an always-mounted polite live region (role=status), so screen readers announce it. | Not yet verified: no evidence record. WCAG 4.1.2. |
| MUST | ARIA: The copied state paints --color-on-status ink on the --color-success fill, which passes 3:1 non-text contrast in every theme. | Not yet verified: no evidence record. WCAG 4.1.2. |
| MUST | ARIA: The heading defaults to h3; set headingLevel (2 to 6) so it fits the page outline. | Not yet verified: no evidence record. WCAG 4.1.2. |
| MUST | ARIA: The section root carries the resolved UI language so localized labels override an English article-body boundary. | 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. | Manual review, last on 2026-11-04. |
| MUST NOT | Maintainers: Do not invent parallel primitives inside this folder. | Release review; not machine-checked. |
| MUST NOT | Maintainers: Do not promote to stable without production consumer evidence. | Release review; not machine-checked. |
