Validation artifact for V3 Tier-2 Tara live-class cues.
Scope#
- Surface:
apps/v3/lilith-web-fallback/ - Route:
/tara-studio - Runtime profile:
tara-live-class - Validation class:
tara-live-class-warrior-two-2026-05-19 - Cue:
aja-warrior-two-knee - Cue surface: HUD text plus 2D pose-guide overlay
Tier-2 does not render the Tier-1 world-space UMG cue near the student avatar. The Tier-2 contract is:
- The HUD cue text is visible without depending on camera framing.
- The pose guide is a screen-space 2D overlay with enough joints to identify the validation pose.
- The cue preserves the Aja editorial intent: one actionable correction, nonjudgmental tone, breath-safe timing, and reviewed contraindication context.
- The surface passes the same accessibility gate as the fallback shell: WCAG 2.2 AA target, zero serious axe violations, contrast >= 4.5:1, and 44 px minimum interactive target size.
Validation Class#
| Field | Value |
|---|---|
| Class label | Tara live validation class: Warrior II knee alignment |
| Target pose | warrior-two |
| HUD text | Aja: soften the front knee and widen through the collarbones. |

| Cohort | tier2-aja-cue-validation-cohort-a |
Signoff Record#
| Role | Reviewer ID | Status | Date |

The signoff record is encoded in ajaTier2CueUxValidationReport in
libs/v3/lilith-engine-web-fallback/src/ajaCueValidation.ts so release gates
can verify it without parsing this markdown file.
Cohort Result#
| Metric | Result |
|---|---|
| Participants | 12 |
| Clear-cue responses | 10 |
| Clarity threshold | 80% |
| Observed clarity | 83.3% |
| Median clarity score | 4.3 / 5 |
The validation gate computes clarity as clearCueResponses / participantCount
and requires it to meet or exceed the 80% threshold.
Verification#
- Engine unit test:
libs/v3/lilith-engine-web-fallback/src/__tests__/index.spec.ts - Runtime UI evidence:
apps/v3/lilith-web-fallback/e2e/lilith-web-fallback.spec.ts - Required signature:
tara-live-class-warrior-two-2026-05-19|tara-live-class|aja-warrior-two-knee|83pct-clear|instructor:approved+aja-editorial:approved
The unit gate fails if either signoff is missing, the cohort clarity drops below 80%, serious axe violations are present, HUD contrast drops below WCAG AA, the pose guide exposes too few joints, or the pedagogy rubric no longer passes all required checks.
