LUME Chain 2 — Sky Garden Duncan-parity push

**Status:** RELEASED (plan + patches ready to apply, live verification pending) **Subject:** Drive LUME Sky Garden mode on Mac4 to Duncan Fewkes parity in visual feel. **Started:** 2026-05-08 **Released:** 2026-05-08 **Chain owner:** Mohamed **Execution model:** META:OMEGA + META:HYDRA collapsed (single pass), 8-lens reviewed **Prerequisite:** Chain 1 (Echelon Layer 4 + 128D Temporal Closure) released same day, see `docs/chains/RELEASE-CHAIN-1.md`. This release bundles a VALIDATED PLAN + READY-TO-APPLY PATCHES for closing the visual gap between LUME Sky Garden mode and Duncan Fewkes-grade visuals on Mac4. It does NOT contain a fully shipped + verified live system. Live verification is gated on Codex / Mohamed applying the patches on Mac4 and recording side-by-side OBS comparison footage. The release covers W13.0 (sky parallax + god rays + breath modulation), W13.1 (pond reflection + DOF), and W13.2 (body subsurface + heat shimmer). W13.3 (operator camera overlay), W13.4 (cinematic framing), and W13.5 (show director) are deferred to a follow-up chain per the 8-lens review (W13.5 was identified as over-architecture risk; W13.3 + W13.4 require partial GUI authoring outside Codex's autonomous range). | # | Criterion | Verification status | |---|-----------|---------------------| | 1 | Side-by-side OBS comparison: Mac4 Sky Garden vs Duncan reel reference, must read as "same family" | **BLOCKED on Codex applying patches + recording on Mac4.** Patches READY (12 artifacts in `Desktop/omega-output/skygarden-duncan-parity-20260508/patches/`). Reference corpus AVAILABLE (`[home-path]` — 82 reels × 12 frames). | | 2 | No FPS regression on Mac4 (60fps min at 1080p) | **PATCHES BUDGETED FOR THIS GATE.** Review Lens 1 (Feasibility) sized each patch against Radeon 780M's 9 TFLOPS budget. Total predicted W13.0+W13.1+W13.2 GPU cost: ~6.5ms within remaining 7ms budget after baseline ~9ms. Live verification BLOCKED on capture. | | 3 | No new external runtime cost (no jump in K11↔Mac4 traffic, no new endpoints) | **DESIGN COMPLIANT.** All W13.0/W13.1/W13.2 changes are local Mac4 GPU passes. No new K11↔Mac4 wire format. No new UDP ports. | | 4 | Sky Garden remains compatible with Wave 9 visual presets (LumeFrozenFlow, LumeKaleidoscope) | **DESIGN COMPLIANT.** Review Lens 3 (Risk) audited shared globals; new W13 globals are gated by `*Active` floats matching W11.4 BodyGlow pattern. Injection points ordered (god rays + heat shimmer at `BeforeRenderingPostProcessing`, kaleido at `AfterRenderingPostProcessing`) so the kaleido mirror catches W13 effects correctly. Live verification BLOCKED on running both modes after patch application. | **Honest summary:** All 4 criteria are GATED on live capture. The patches are ready, the budget math works out, the architecture is compa
