WO-5 T4/T5: WebGPU Gaussian-splat viewport, verified against real hardware
hunt

T5: buildPlaceholderSplat() in placeholderSplat.ts - a deterministic
(seeded), auditable procedural head-shaped splat cloud (position, scale,
rotation quaternion, color, opacity, per-splat jaw/eyelid skinning
weights) standing in for the not-yet-built GaussianAvatars/FLAME/TetGS
trained asset. Data-shape matches the standard Gaussian-splat attribute set
so a real trained asset drops in as a data change, not a renderer rewrite.
T4: SplatRenderer.ts + shaders.wgsl.ts - the WebGPU pipeline. Two-pass
structure: a deform compute pass turns ARKit-52 weights (jawOpen, blink)
into per-splat position/rotation deltas via quaternion rotation around a
jaw hinge and lid-line compression; a billboard render pass draws each
Gaussian as a camera-facing quad with a soft radial falloff.
DECOUPLED RENDER LOOP (the WO-5 architectural guardrail): startRenderLoop()
calls requestAnimationFrame unconditionally every frame and renders
whatever currentWeights currently holds. SplatViewport's own network-feed

Rebuild Miranda-Engine from scratch — real repo, real content

This repo was previously a stale fork of microsoft/agent-framework with no
connection to this project. Replaced entirely, at the owner's direction,
with:
- A real 6-crate Cargo workspace skeleton (miranda-core/ipc/audio/nodes/
supervisor/transport) — cargo build verified clean.
- The prior-attempt eve-ecc client (Vite+React+TS, @xyflow/react ACE Cortex
UI) carried forward as client-apps/web, plus its ace-controller backend
and dev scripts — genuinely reusable prior work, not rebuilt from zero.
- The eve-ecc design docs (ECC5 certification, IDE/backend contract, the
orchestration pivot writeup) preserved as-is.
- A new Instant Presence Standard doc expanding the prior IPS table with
the No Loop Video Protocol (instantly-alive, waist-up, waving,
choreographed micromovement) that was missing from the original spec.
- images/ with the EVE reference image plus two real prototype stills from
the first attempt.
