UI Micro-Interactions Component Map (MI6)

This document maps StellaOps UI components to their interaction types and motion token usage. Components must use tokens from the catalog (tokens/motion.scss, motion-tokens.ts) rather than bespoke values.

Token Catalog Reference

Token CSS Variable Duration Use Case
durationXs --motion-duration-xs 80ms Focus rings, instant feedback
durationSm --motion-duration-sm 140ms Hover states, button presses
durationMd --motion-duration-md 200ms Modal open/close, panel slide
durationLg --motion-duration-lg 260ms Page transitions, accordions
durationXl --motion-duration-xl 320ms Complex sequences, onboarding
easeStandard --motion-ease-standard cubic-bezier(0.2,0,0,1) Default for all transitions
easeEntrance --motion-ease-entrance cubic-bezier(0.18,0.89,0.32,1) Elements appearing
easeExit --motion-ease-exit cubic-bezier(0.36,0,-0.56,-0.56) Elements leaving
easeBounce --motion-ease-bounce cubic-bezier(0.34,1.56,0.64,1) Playful feedback only

Component Mapping

Component Interaction Type Tokens Used Reduced-Motion Behavior
Button (primary) Hover lift, press scale durationSm, easeStandard, scaleSm No transform, instant state change
Button (secondary) Hover border, press durationXs, easeStandard Instant state change
Modal/Dialog Fade + slide up durationMd, easeEntrance/Exit, translateMd Instant show/hide
Dropdown/Menu Fade + scale durationSm, easeStandard, scaleSm Instant show/hide
Toast/Snackbar Slide in, auto-dismiss durationMd, easeEntrance, translateLg Instant show/hide
Accordion Height expand durationMd, easeStandard Instant toggle
Tabs Indicator slide durationSm, easeStandard Instant indicator
Progress bar Width fill durationMd, easeStandard No animation, instant fill
Spinner/Loader Rotate animation N/A (CSS keyframe) Static icon or hidden
Skeleton Shimmer pulse durationXl, easeStandard Static skeleton, no shimmer
Badge (status) Scale pop on change durationXs, easeBounce, scaleSm No scale, instant
Focus ring Fade in durationXs, easeStandard Always visible, no fade
Tooltip Fade + offset durationSm, easeEntrance, translateSm Instant show/hide
Banner (info) Slide down durationMd, easeEntrance, translateMd Instant show/hide
Error state Shake animation durationSm, easeStandard No shake, border only

Perf Budget Compliance (MI5)

Metric Budget Measurement
Interaction response <= 100ms Time to visual feedback
Animation frame (avg) <= 16ms Chrome DevTools Performance
Animation frame (p95) <= 50ms Chrome DevTools Performance
Layout shift <= 0.05 CLS Lighthouse CI
LCP placeholder Show within 400ms Lighthouse CI

Validation Rules

  1. Lint rule: ESLint/Stylelint blocks non-catalog easing values in .scss and .ts files
  2. Storybook check: All component stories must demonstrate reduced-motion variant
  3. Playwright check: Snapshot tests run with --disable-animations and reduced-motion emulation
  4. CI gate: Perf budget failures block merge

TTFS Component Interactions

Per advisory §15: Component-to-interaction mapping for Time-to-First-Signal.

FirstSignalCard Component

Location: src/app/features/runs/components/first-signal-card/

Interaction Trigger Duration Easing Token
Skeleton shimmer Initial load 2s loop linear Custom keyframe
Skeleton → Content Signal loaded 200ms easeEntrance durationMd
Badge appear Kind change 140ms easeEntrance durationSm
Progress update Phase change 140ms easeStandard durationSm
Button hover Mouse enter 80ms easeStandard durationXs
Button press Click 80ms easeExit durationXs
Error shake Load error 260ms easeStandard durationLg

Telemetry Events:

Event Trigger Payload
ttfs_start Component mount { runId, surface, t }
ttfs_signal_rendered Signal displayed { runId, surface, cacheHit, source, kind, ttfsMs }
ui.click.action Action button click { runId, actionType, target }
ui.retry Retry button click { runId, errorCode }

Accessibility:

Requirement Implementation
Focus visible :focus-visible outline on buttons
Screen reader aria-live="polite" on content area
Loading state aria-busy="true" on card
Status role="status" on badge
Keyboard Tab navigation, Enter/Space activation
Reduced motion Disable shimmer, use instant transitions

EvidencePanel Component

Location: src/app/features/evidence/evidence-panel.component.ts

Interaction Trigger Duration Easing Token
Tab switch Tab click 200ms easeStandard durationMd
Panel expand Accordion open 260ms easeEntrance durationLg
Panel collapse Accordion close 200ms easeExit durationMd
Copy success Copy button 140ms easeEntrance durationSm
Copy tooltip After copy 2s visible — —
Export progress Export start Indeterminate linear Spinner

Telemetry Events:

Event Trigger Payload
finding_open Panel mount { findingId, entryPoint, t }
proof_rendered Proof visible { findingId, proofKind, source, t }
ui.copy.verify_command Copy verify cmd `{ type: 'cosign'
evidence.export Export complete { findingId, fileSize }

ProofSpine Component

Location: src/app/features/evidence/components/proof-spine/

Interaction Trigger Duration Easing Token
Hash truncation expand Hover/focus 140ms easeStandard durationSm
Copy single Copy button 80ms easeExit durationXs
Copy all Copy all button 140ms easeEntrance durationSm
Status badge Load 200ms easeEntrance durationMd

TTFS State Machine

FirstSignalCard:
  idle → loading → loaded
                ↘ unavailable
                ↘ error → (retry) → loading

EvidencePanel:
  idle → loading → loaded
                ↘ partial (some proofs failed)
                ↘ error
