2722This report maps each reviewer objection to current evidence. It does not claim objections are fully closed where they are not. It states precisely what the evidence shows and what it does not show.
2723
2724## Objection 1: No real engine data
2725
2726**Evidence available:**
2727- Engine-realistic synthetic capture at 1920×1080 with GPU-measured dispatch timing (see `generated/engine_realistic/engine_realistic_validation_report.md`)
2728- DAVIS external replay (3 captures, real video, proxy structural signals): `generated/external_davis/`
2729- Sintel external replay (5 captures, ground-truth reference, synthetic renderer): `generated/external_sintel/` (if run)
2730- Engine-native infrastructure complete: manifest schema, CLI (`run-engine-native-replay`), playbooks for Unreal/Unity/custom renderer
2731
2732**What this closes:** Pipeline execution on non-trivial data at production resolution (1080p) with measured GPU timing.
2733
2734**What remains open:** Real renderer reprojection error, real production content, real TAA scheduling. Closes when a real engine capture is provided.
2735
2736**Exact next step:** `cargo run --release -- run-engine-native-replay --manifest examples/engine_native_capture_manifest.json --output generated/engine_native`
2737
2738## Objection 2: Demo B not renderer-integrated
2739
2740**Evidence available:**
2741- `docs/demo_b_production_integration.md` — exact integration hook in Vulkan/DX12, what a renderer team would need, what would be measured
2742- Demo B trust signal validated on engine-realistic synthetic specular-flicker region
2743- Fixed-budget allocation policy comparison is complete in internal suite
2744
2745**What this closes:** Exact integration design with code-level specificity. Trust signal validated on specular content.
2746
2747**What remains open:** In-renderer measurement of ROI vs non-ROI sample distribution on real content. Closes when renderer team provides access to pre-denoiser sample budget allocation code.
2748
2749**Exact next step:** Share `docs/demo_b_production_integration.md` with renderer team and provide `trust_out` buffer format spec.
2750
2751## Objection 3: Show me Unreal or internal renderer buffers
2752
2753**Evidence available:**
2754- `docs/unreal_export_playbook.md` — step-by-step Unreal RenderDoc export procedure
2755- `docs/unity_export_playbook.md` — step-by-step Unity export procedure
2756- `docs/custom_renderer_export_playbook.md` — custom renderer integration
2757- `examples/engine_native_capture_manifest.json` — manifest format for engine-native capture
2758- Engine-realistic synthetic buffers at 1080p follow the same schema
2759
2760**What this closes:** Complete playbook and manifest infrastructure — a renderer team can provide buffers with no code changes to this crate.
2761
2762**What remains open:** Actual Unreal or internal renderer buffers. Closes when a capture is provided.
2763
2764**Exact next step:** Follow `docs/unreal_export_playbook.md` on any Unreal project with TAA enabled.
2765
2766## Objection 4: Show me where this sits in the frame graph
2767
2768**Evidence available:**
2769- `docs/frame_graph_position.md` — complete pass ordering, resource dependencies, barrier requirements (`srcStageMask`/`dstStageMask`), Unreal RDG pseudocode
2770- `docs/async_compute_analysis.md` — barrier semantics, async scheduling analysis, no-stall proof
2771
2772**What this closes:** Complete technical specification of frame graph insertion, barrier requirements, and async compatibility.
2773
2774**What remains open:** Actual RenderDoc/PIX capture showing the pass in a live frame timeline. Closes when real engine capture is provided.
2775
2776## Objection 5: Show me it doesn't stall async
2777
2778**Evidence available:**
2779- `docs/async_compute_analysis.md` — explicit analysis showing no CPU sync point required in production
2780- Minimum kernel has no render targets, no framebuffer attachments, pure compute
2781- All dependencies (current_color, history, depth, normals) are GPU-resident inputs
2782- Outputs (trust, alpha, intervention) are GPU-resident and consumed by the subsequent resolve pass
2783- `pollster::block_on()` in the wgpu evaluation harness is evaluation-only, not production
2784
2785**What this closes:** Architectural proof that no CPU stall is required.
2786
2787**What remains open:** Measured async overlap confirmation via GPU trace (NSight/PIX). Closes when real engine capture is provided with profiling.
2788
2789## Objection 6: 4K dispatch proof
2790
2791**Evidence available:**
2792- wgpu binding limit raised to `u32::MAX` — removes 134 MB binding cap
2793- 4K synthetic probe (3840×2160 zero-filled buffers) executed via `run-gpu-path` — see `generated/final_bundle/gpu_execution_report.md` for `gpu_4k_synthetic_probe` row
2794- 8×8 workgroup tiling is resolution-independent by design (dispatch is `ceil(W/8) × ceil(H/8)`)
2795
2796**What this closes:** Architecture limit removed; dispatch feasibility tested at 4K resolution with real wgpu path.
2797
2798**What remains open:** 4K with real engine buffers (real content, production memory pressure, real adapter). Closes when real 4K engine capture is provided.
2799
2800## Objection 7: Motion disagreement in cost model despite no benefit
2801
2802**Evidence available:**
2803- Motion vectors binding completely removed from minimum GPU kernel (`@group(0) @binding(2)` dropped)
2804- `let _unused_motion` line removed
2805- Minimum kernel binding count reduced from 9 to 8 bindings
2806- Motion disagreement remains as `motion_augmented` optional extension only, reported separately
2807- Cost model updated to reflect minimum-path-only binding count
2808
2809**What this closes:** The minimum path no longer pays for motion disagreement. Cost model correctly reflects minimum binding set.
2810
2811**What remains open:** Nothing for this objection. It is closed.
2812
2813## Objection 8: Real engine memory access pattern
2814
2815**Evidence available:**
2816- LDS-optimized kernel uses `var<workgroup> tile: array<f32, 100>` — 10×10 luma cache for 8×8 workgroup
2817- Color texture reads for neighborhood gates reduced from 16/pixel to ~1.6/pixel
2818- Engine-realistic 1080p dispatch timing: see `generated/engine_realistic/engine_realistic_validation_report.md`
2819
2820**What this closes:** LDS optimization directly addresses the cache-thrash concern for the 3×3 neighborhood gates. Dispatch timing at 1080p is measured.
2821
2822**What remains open:** NSight L1/L2 cache counter data on the target GPU with real engine buffer layout. Closes when real engine capture is provided with hardware profiling.
2823
2824## Objection 9: DAVIS = weak structural signals
2825
2826**Evidence available:**
2827- Signal quality assessment in `generated/external_davis/external_validation_report.md` — documents which signals are derived-low-confidence (block-matching motion, relative-depth, doubly-derived normals)
2828- Sintel provides ground-truth depth, normals, and motion vectors as the stronger structural signal dataset
2829- Table in DAVIS report: "What Sintel closes vs what engine capture closes"
2830
2831**What this closes:** Honest disclosure of DAVIS signal quality and implications for gate accuracy. Sintel partially closes the structural signal gap.
2832
2833**What remains open:** Real engine structural signals (real reprojection error, real subpixel motion, real specular structure). Closes when real engine capture is provided.
2834
2835## Objection 10: Sintel = proxy renderer, not real pipeline
2836
2837**Evidence available:**
2838- Engine-realistic synthetic scene simulates real-engine artifacts that Sintel lacks: TAA jitter, reprojection noise at depth discontinuities, specular flickering, subpixel motion vector noise, disocclusion events
2839- Explicit per-artifact mapping in `generated/engine_realistic/engine_realistic_validation_report.md` (Scene Design table)
2840
2841**What this closes:** Narrower gap between synthetic evidence and real-engine behavior via engine-realistic bridge.
2842
2843**What remains open:** Real engine TAA history buffer, real production content, real pipeline scheduling. Closes when real engine capture is provided.
2844
2845## Objection 11: Mixed regime not fully demonstrated
2846
2847**Evidence available:**
2848- Internal confirmation computed from actual pixel signals on `noisy_reprojection` scenario: aliasing enrichment 2.31×, variance enrichment 3.63× — see `generated/mixed_regime_confirmation_report.md`
2849- Confirmed from pixel-level signal computation on actual scenario data, not from architectural claims
2850- Engine-realistic scene contains both aliasing-pressure (thin geometry at disocclusion band) and variance-pressure (specular flickering, subpixel reprojection noise) co-active in the same ROI frame
2851
2852**What this closes:** Internal confirmation is from measured signal values. Engine-realistic synthetic closes "show me both signals simultaneously" at 1080p.
2853
2854**What remains open:** Engine-native mixed-regime confirmation. Closes when a thin-geometry-under-motion real engine capture is provided.
2855
2856## Objection 12: Won't sign until we see it on a real pipeline
2857
2858**Summary table:**
2859
2860| Item | Internal closes? | External closes? | Status |
2861|------|-----------------|------------------|--------|
2862| Frame graph position | ✓ (docs/frame_graph_position.md) | — | Closed |
2863| Async stall proof | ✓ (docs/async_compute_analysis.md) | PIX/NSight trace | Architecture closed |
2864| Motion disagree removed | ✓ (kernel binding dropped) | — | Closed |
2865| 4K dispatch | ✓ (limit fix + probe) | Real 4K capture | Architecture closed |
2866| LDS optimization | ✓ (workgroup tile) | NSight benchmark delta | Code closed |
2867| GPU timing 1080p | ✓ (engine-realistic) | Engine capture | Measured (synthetic) |
2868| DAVIS signal quality | ✓ (documented) | Real engine depth/normals | Documented |
2869| Sintel proxy gap | ✓ (engine-realistic narrows it) | Real engine capture | Partially closed |
2870| Mixed regime | ✓ (internal + engine-realistic) | Engine thin-geometry capture | Partially closed |
2871| Real engine buffers | — | ✓ one capture | Open |
2872| Demo B in renderer | — | ✓ renderer team | Open |
2873| Real memory pattern | — | ✓ NSight profile | Open |
2874
2875**The single remaining step:** One real engine capture following `docs/unreal_export_playbook.md` or `docs/unity_export_playbook.md`. All internal infrastructure is complete and gated. The pipeline is waiting.
2876
2877```bash
2878cargo run --release -- run-engine-native-replay \
2879  --manifest examples/engine_native_capture_manifest.json \
2880  --output generated/engine_native
2881```
2882
2883## What Is Not Proven
2884
2885- Real engine reprojection error on production content
2886- Async overlap measurement in a live engine frame graph (NSight/PIX required)
2887- Demo B in-renderer integration (renderer team participation required)
2888- Real production memory access pattern (NSight/PIX profiling required)
2889
2890## Remaining Blockers
2891
2892All internal items are closed. The remaining blockers are:
2893
28941. Real engine capture (Unreal, Unity, or custom renderer following the playbooks)
28952. Engine-integrated GPU profiling (NSight/PIX) to confirm async overlap
28963. Demo B in-renderer integration (renderer team participation required)
