Outcome

Adds the development-only comparison prototype required by SPEC-003 so Orbit and Dial task-card signals can be reviewed at real desktop and mobile sizes before production integration.

Included

  • evidence-backed checklist/subtask progress contract with no invented fraction
  • estimate/health signal orb and 14-day activity heat rail
  • priority, owner, milestone, and exception treatments
  • 44px keyboard focus targets and explicit card/orb/rail text alternatives
  • dark/light and comfortable/compact prototype controls
  • reusable typed signal fixture layered onto the shared frontend test toolkit
  • checked desktop and mobile screenshot evidence

Verification

  • Node.js 24
  • pnpm run test -- --reporter=dot (10 files, 65 tests)
  • pnpm run build
  • Playwright accessibility snapshot at 1440x1000 and 390x844
  • browser console: 0 errors, 0 warnings
  • git diff --check

Boundaries

The route is available only when import.meta.env.DEV is true. Fixtures are synthetic; screenshots are design evidence, not live delivery or user-acceptance evidence. Production TaskCard integration and specialist variant selection remain follow-up work.

Summary by CodeRabbit

  • New Features
    • Added task-card signal visuals for progress, health, activity, priority, ownership, milestones, and exceptions.
    • Added Orbit and Dial signal variants with compact and comfortable density options.
    • Added light and dark theme support with accessible labels, tooltips, and keyboard-friendly controls.
    • Added a prototype page for comparing task-card signal presentations.
  • Documentation
    • Documented prototype evidence, supported variants, visual themes, accessibility checks, and verification results.
  • Tests
    • Added coverage for progress handling, activity tiers, signal rendering, and accessibility text.

Review Change Stack

Warning

Review limit reached

@JustAGhosT, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 72 minutes

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

📝 Walkthrough

Walkthrough

Added task-card signal contracts, accessible visual indicators, reusable fixtures, tests, a development-only prototype route, and documentation for Orbit and Dial signal variants.

Changes

Task-card signal prototype

Layer / File(s) Summary
Signal contracts and utilities
frontend/src/components/taskCardSignals.ts, frontend/src/components/taskCardSignals.test.tsx, frontend/src/test/fixtures.ts
Added signal models, progress and activity calculations, accessible labels, tests, and a reusable task-card fixture factory.
Signal indicator components
frontend/src/components/SignalOrb.tsx, frontend/src/components/HeatRail.tsx, frontend/src/index.css
Added accessible progress and activity indicators with variant, health, density, and theme-specific rendering.
Prototype page and route
frontend/src/prototypes/TaskCardSignalPrototypePage.tsx, frontend/src/components/TaskCardSignalPrototype.tsx, frontend/src/App.tsx
Added synthetic task states, Orbit and Dial comparison columns, theme and density controls, task-card rendering, and a development-only prototype route.
Prototype verification evidence
docs/evidence/ui-prototypes/README.md
Documented the capture route, signal variants, screenshots, and verification results.

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

Merge Risk: 🔵 Low · up to e5853

The development-only prototype is mergeable with owner awareness: the unknown dial state may appear nearly complete, and the documented fixture provenance should be aligned with the implementation.

P2 Badge Raise the remaining faint header text to AA contrast

Although the card metadata was moved to --fg-muted, the refreshed variant header still renders its description and count with --fg-faint; that token is only about 2.58:1 against the dark column and 4.20:1 against the light column, below the 4.5:1 requirement for this 9–12px text. Consequently, both committed captures still fail the SPEC-003 contrast gate; use an AA-capable token for these labels.

P2 Badge Use theme-specific priority accent tokens

These fixed Tailwind colors do not switch to SPEC-003's light-theme accent palette. In the light capture, for example, the high-priority orange-500 stripe has only about 2.80:1 contrast against the white card, below the 3:1 UI-component requirement; define and use the specified semantic priority tokens so the prototype actually validates both themes.

P2 Badge Keep orb unit labels at the specified minimum size

After the SVG diameters were corrected, the current orb still renders the unit label at 8px in both densities. SPEC-003 §3.2 sets a 10px minimum at compact size, so the compact evidence is not showing the specified legible center content; raise the unit label to at least 10px and verify it still fits the 24px orb.
