Design system: remove colour-only status semantics, add non-colour markers and shared-home title handling

[BigSimmo]

Motivation

• Remove colour-only clinical/status meaning and avoid colouring numerals to preserve unambiguous clinical semantics and accessibility.
• Pin design-system contract metrics to reflect the repaired state so the baseline counts accurately represent executable debt.
• Keep the shared-home browser/document title aligned with the visible mode heading for clearer assistive-technology and deep-link behaviour.
• Record the delivery plan, prompt, and review evidence for PR 1 of the live convergence programme.

Description

• Replace colour-only status markers with geometric/border variants in src/components/ui-primitives.tsx and adjust the calculator severity visuals in src/components/calculators/calculator-ui.tsx to add non-colour patterns and an aria-label on the severity bar.
• Remove status-coloured numerals and change the evidence badge paint in src/components/clinical-dashboard/visual-evidence.tsx to use neutral heading text colour.
• Add sharedHomeDocumentTitle in src/lib/ui-copy.ts, export it, add server generateMetadata in src/app/(search-app)/page.tsx, and set document.title on the client in src/components/ClinicalDashboard.tsx to keep titles aligned with the selected mode.
• Update scripts/design-system-contract-baseline.json to set colourOnlyStatusIndicators and statusColouredNumerals to 0 and clear their debtByPath entries to reflect the repaired debt.
• Add tests and verification: tests/status-semantics-contract.test.ts and tests/shared-home-metadata.test.ts, and extend tests/ui-accessibility.spec.ts with a title-alignment Playwright check.
• Add documentation and process artifacts: docs/plans/design-system-live-convergence-plan.md, docs/prompts/codex-cloud-design-status-semantics.md, and update docs/design-system/GATES.md plus branch review records entries.

Testing

• Ran the design-system contract check with npm run check:design-system-contract, and the contract metrics and per-path counts reflect the intended zeroing of the two status metrics (passed).
• Executed focused Vitest suites covering the new and updated unit/DOM tests including tests/status-semantics-contract.test.ts and tests/shared-home-metadata.test.ts, and these focused tests passed.
• Ran the focused Playwright/accessibility scenario for shared-home title behaviour and the accessibility Chromium checks used in CI, and the focused browser tests passed.
• A full unit run was attempted; focused runs passed while unrelated environment hook timeouts in the full suite were observed and flagged separately (these timeouts are not caused by the change).

📝 Walkthrough

Walkthrough

The change defines a design-system convergence programme and Cloud prompt. It updates clinical status indicators, calculator accessibility labels, baseline metrics, and contract tests. It also adds branch review records for validation and rollout evidence.

Changes

Design-system convergence

Layer / File(s)	Summary
Convergence programme and implementation contract docs/plans/design-system-live-convergence-plan.md, docs/prompts/codex-cloud-design-status-semantics.md, docs/branch-review-records/*.record.md	The plan and Cloud prompt define six delivery tranches, status semantics, verification gates, rollback rules, handoff requirements, authorization boundaries, and stop conditions. Review records document validation results.
Clinical status semantics and contract validation src/components/calculators/calculator-ui.tsx, src/components/clinical-dashboard/visual-evidence.tsx, src/components/ui-primitives.tsx, scripts/design-system-contract-baseline.json, tests/status-semantics-contract.test.ts	Calculator bands now expose score ranges and tone-specific borders. Status markers use distinct geometry. The evidence-gap text uses heading color. Status debt metrics are zeroed and covered by contract tests.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to 97e02

This PR removes colour-only status cues, adds non-colour markers, and aligns shared-home titles with the visible mode; focused checks pass and no implementation issue requires blocking merge. The delivery plan still treats provider-backed PR publication as safe without explicit user authorization, so owner awareness is required for that bounded permission risk.

Check name	Status	Explanation	Resolution
Description check	⚠️ Warning	The description explains the changes and testing, but it omits the required Summary, Risk and rollout, Clinical Governance Preflight, and Notes sections.	Use the repository template headings and complete the required risk, rollback, production-effects, RAG-impact, governance, and verification entries.
Docstring Coverage	⚠️ Warning	Docstring coverage is 44.44% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff.

tests/status-semantics-contract.test.ts checks source text only. Add a DOM test that renders ScoreBandBar and asserts its img role, accessible name, and tone-pattern classes. Render a status-marker consumer and assert the ready, review, and muted geometry classes. Keep the scanner assertions.
