Milestone

Built-in pages — DLS-PAGE-014 conservative built-in data-state exposure validation.

Specification coverage

• Section 10 Built-in Pages
• Requirement IDs: DLS-PAGE-014

What shipped

• Added conservative implementation-local built-in page definition support for definition.data-state.
• Validated that built-in page definitions declare independent availability, completeness, and freshness exposure markers.
• Rejected unknown built-in data-state axes and non-canonical marker values.
• Expanded validator unit coverage for accepted and rejected DLS-PAGE-014 cases.
• Updated PLAN.md and README.md to record the slice and the remaining ambiguity in the specification vocabulary.

Gates

• npm install ✅
• npm run typecheck ✅
• npm run lint ✅
• npm test ✅

Next milestone

Built-in pages — next conservative Section 10 slice for runs page link coverage without inventing presenter semantics.
