How this rule is fixed
Not in the deterministic fixer pilot registry (stub or not yet wired). Use the After example below as the target state and remediate manually or extend pilot-registry.json.
Detection module: docs/design/ux-audit/deterministic-design-rules.md#det-studio-h1. Scroll down for Before / After examples and Evidence and remediation steps.
Purpose
Every Studio workspace route must expose exactly one visible h1 in main (or the Cap header slot). Missing H1 breaks page_identity scoring, screen-reader outline, and DET.STUDIO.TITLE_NAV_MATCH.
Passing signals
- One
h1with non-empty text insidemain.fc-mainor.fc-page-header. - Visually hidden
h1is allowed only when a visible labelled equivalent exists (prefer visible H1 for operators).
Failing signals
- No
h1; onlyh2or rail label carries the page name. - Empty
h1or icon-only header.
