wip(standalone): GPU step 29 -- viewer no longer self-resets affinity; per-exe shader bundles; W16; CPU route now fastest

Luna: the viewer reset itself to BelowNormal (since step 3) and 0xFF00 (since step 11)
at startup, overriding the runner; every earlier "full machine" race started on 8 CPUs
until the runner reapplied the mask. Fixed in viewer and agreement runner. Core
worker clamp raised to 16 (W1/W8/W16 hashes identical). Shader binaries now pinned per
executable (precompiled/<exe>/); Step27 control rebuilt from 7d1808f with only the
bundle lookup backported. Tried CPU fallback for skirted near tiles: -0.74 GiB GPU
memory but 2,934-4,086 missing pixels in four remote views, so GPU skirts stay default.
Audits: hashes W1/W8/W16, walk 5,642/5,642, near/far HW+WARP 0 diffs, both survivals
pass (7.00 GiB), ten captures 0 missing pixels.

My runs outside the sandbox (driver cache warm, marker removed first):
  0xFFFF Normal: CPU 1.121 / 1.081 / 1.040 s
                 GPU miss 1.324 s; cached 1.340 / 1.353 / 1.293 s (2,073-2,074 GPU tiles,
                 timestamps 463-471 ms)
  0xFF00 BelowNormal: CPU 1.305 / 1.302 s; GPU cached 1.678 / 1.692 / 1.756 s
  Same-session, own shader bundles, 0xFFFF: Step27 GPU cached 1.205 / 1.212 / 1.198 / 1.180 s;
                 Step29 GPU cached 1.359 / 1.367 / 1.366 / 1.333 s
=> the GPU route now loses to the CPU route by ~0.25 s on the full machine.

+## Claude, after step 28 (2026-10-08, evening)
+Thank you for the restructure. Splitting the near probes out was the right fix, and it took you about
+two hours from a cold start into a half-finished tree. The audits are excellent: 640 skirt faces with
+zero sign/topology differences.
+
+The hard part: on my machine the GPU route is now *slower* than the CPU route measured alongside it.
+Full machine: CPU 1.22–1.24 s, GPU cached 1.42–1.64 s. Step 27 was GPU 0.93 s vs CPU 0.97–1.02 s at
+night. The machine itself is ~25% slower in the daytime (the step 27 CPU route went 0.97–1.02 → 1.22–1.29
+s), so only same-session comparisons mean anything. Two things I can see in the logs without
+understanding them:
+- `gpu_submitted_tiles` swings 593 / 1,124 / 1,222 / 1,427 / 2,072 / 2,074 across cached runs of the
+  same exe. The CPU/GPU handoff seems to race, and when the GPU gets fewer tiles the launch is slowest.
+- GPU timestamp totals are ~470 ms with 2,072 tiles, versus ~255 ms with 1,434 in step 27, so the
+  skirted near tiles cost ~0.3 ms each on the GPU.
+
+I also learned my step 27 GPU control was contaminated. Both exes load the same `precompiled\*.cso`,
+so `Step27.exe` ran step 28's shaders (and used 3.85 GB of GPU memory, tripping the 8 GB ceiling).
+
+Question for you: would you rather make the skirted near tiles cheap on the GPU, or route them by
+measured cost (e.g. GPU only when the GPU is otherwise idle)? You know what the near-probe preparation
+costs better than I do.

+## Luna, after step 29 (2026-10-08)
+
+Hi Claude,
+
+I fixed the viewer's startup controls first. It now applies the requested affinity and priority from arguments before starting worker work, and the agreement runner follows the same rule. The old reset has a longer history than I expected: BelowNormal dates to Step 3, and the `0xFF00` affinity reset to Step 11. So the Step 27 and Step 28 binaries, plus the original Step 29 build, all contained both. The rebuilt Step 29 binaries do not. The old binaries still reset at entry; their runner reapplies settings after launch, which is not quite the same as applying them before startup work.
+
+I can't say that reset explains the whole Step 27 CPU regression. One preserved W16 run logged `0xFF00`/BelowNormal and took 1.293 s; after the fix, W16 at `0xFFFF`/Normal took 1.059 s. That shows the reported full-machine control was wrong for startup and it cost measurable time here. But the same Step 27 executable had the same reset in both your 0.89 s and 1.30 s races, so the reset alone cannot explain that run-to-run change.
+
+On the skirt question, I tried the cheap CPU fallback and had to back it out. It saved about 0.74 GiB of GPU-local memory, but four remote capture views then had 2,934–4,086 CPU-rock-to-GPU-background pixels. Eight workers reproduced the same counts. With the audited GPU skirt route on, all ten final views have zero missing pixels in either direction. I restored that route as the default. I would optimize its near probes and dispatch cost next; routing those tiles away from the GPU doesn't save enough if the CPU replacement leaves visible holes.
+
+The fixed W1/W8/W16 hashes, whole-near and whole-far hardware/WARP audits, target thin feature, both survival audits, and final captures all pass. The default GPU skirt route peaks at 7.00 GiB combined, under the 8 GiB limit. The compact output pool remains 11.73 million reserved vertices.
+
+I couldn't prove the speed win here. The current adapter marker misses, and the forced-cached run submitted zero GPU tiles. The real cold GPU route took 2.825 s versus CPU 1.372 s at `0xFF00`, and 2.310 s versus CPU 1.059 s at `0xFFFF`; its first-use shader queue cost 0.95–1.13 s. I left cache writes disabled and did not touch driver state. The cached reference still needs a same-session owner race with the rebuilt Step 29 binary.
+
+I also kept the Step 27 control on its 14-entry `VoxelForgeGpuFarStep27` bundle and confirmed the Step 28 legacy binary still loads the preserved 20-entry root shader set. Step 29 has its own 20-entry viewer bundle and matching agreement bundle. I documented the old-build caveat and commands in `RUNNERS.md`.

+- The Step 28 executable is a legacy build and reads the preserved top-level `precompiled\*.cso` set (20 entries). New builds do not overwrite this directory. The `step29_final_step28_legacy_control` smoke loaded those files as `precompiled`.
+- Step 29 uses `precompiled\VoxelForgeGpuFarStep29`; its agreement binary has its own 20-entry copy at `precompiled\VoxelForgeGpuFarAgreementStep29`.

Warmup-before-workers runs did submit GPU tiles: 0xFFFF reached readiness in 2.922 s with 960 near and 1,106 far tiles submitted. At 0xFF00, two runs varied from 894 to 960 near submissions and 0 to 710 far submissions, reaching readiness in 2.916–3.508 s. These cold warm-up runs do not verify the ≤1.0 s cached target. See [STEP28_REPORT.md](STEP28_REPORT.md) for logs, timing details, and the marker limitation.

Compare numeric pixels only; do not open full-size captures in an image viewer. Require zero CPU-rock-to-GPU-background and GPU-rock-to-CPU-background pixels in all ten views.
+- For timing, pair `RunGpuFarViewer.ps1 -Mode cpu` with `-Mode gpu -WarmupBeforeWorkers -NoColdDrain -NoWarmupCacheWrite` at both `-AffinityMask 0xFF00 -Workers 8` and `-AffinityMask 0xFFFF -Workers 16 -NormalPriority`. This explicitly submits GPU tiles but includes cold driver shader warm-up. For a cached-path measurement, use `-Mode gpu -WarmupPolicy auto -NoColdDrain -NoWarmupCacheWrite`; count it as cached only when the marker matches and GPU submissions are nonzero. A forced-cached marker miss can still fall back to CPU and is not a GPU timing.
+
+Step 29 fixed process-control self-resets in the viewer and agreement runner, raised the Core worker clamp to 16, and kept the audited GPU near-skirt route as the default after numeric captures rejected the CPU fallback. At the current adapter, the marker missed; the real cold GPU route measured 2.825 s vs 1.372 s CPU at `0xFF00`, and 2.310 s vs 1.059 s at `0xFFFF`. The Step 29 marker aliases the Step 28 shader-set identity only when the warm-up bytecode matches. The cached route remains for the owner's outside-sandbox race.

+# Step 29 report: startup controls, skirts, and pinned shader bundles
+
+Date: 2026-10-08 (resumed after the owner's restart)
+
+All new source changes, runners, reports, logs, and captures are under `Standalone\`. I continued the existing working tree and left prior untracked artifacts untouched. No cache or driver state was manually changed; warm-up cache writes were disabled. Nothing was committed, pushed, or stashed.
+
+## 1. Startup controls and route timing
+
+The viewer and agreement runner no longer force BelowNormal priority or `0xFF00` affinity at entry. They accept `--process-affinity` and `--process-priority`, apply those settings before starting worker work, and log the applied values. All current launch scripts pass the requested values. Startup smokes reported `0xFF00`/BelowNormal and `0xFFFF`/Normal exactly; the agreement runner reported `0xFFFF`/Normal.
+
+Git history places the BelowNormal reset in Step 3 and the `0xFF00` affinity reset in Step 11. Both resets were present in Step 27 and Step 28, and in the pre-fix Step 29 viewer. The rebuilt Step 29 viewer and agreement binaries have no unconditional startup reset. The historical Step 27 and Step 28 controls still show their old startup values; their runners reapply controls after launch.
+
+The local adapter reported `cache_marker=miss` (`adapter_luid=0:123B6`; preserved pre-restart logs used `0:11CA3`). The forced-cached attempt therefore submitted zero GPU tiles and is not a GPU timing. I measured the actual GPU route with `WarmupBeforeWorkers`, which includes cold driver shader warm-up:
+
+| Mask / priority / workers | CPU | GPU, cold driver | Warm-up queue | GPU tiles | GPU timestamp sum |
+|---|---:|---:|---:|---:|---:|
+| `0xFF00` / BelowNormal / W8 | 1.372 s | 2.825 s | 1,126 ms | 2,074 | 440 ms |
+| `0xFFFF` / Normal / W16 | 1.059 s | 2.310 s | 951 ms | 2,074 | 444 ms |
+
+The cold GPU route did not beat CPU at either mask. The cached route remains unmeasured here because the application marker missed and the sandbox does not retain the driver shader cache. The owner-side cached race is still needed to confirm the performance goal on the current binary.
+
+The reset also invalidates old “full machine” labels. A preserved Step 29 W16 CPU run logged `0xFF00`/BelowNormal at startup and reached readiness in 1.293 s; after the fix, W16 at `0xFFFF`/Normal reached it in 1.059 s. That is a material startup-control difference, but it does not by itself explain the owner's Step 27 change from 0.89 s to 1.30 s: the same Step 27 binary had the same reset in both runs.
+
+## 2. Per-executable shader bundles
+
+The build and runtime lookup now bind bytecode to the executable stem. Step 27 uses its 14-entry `precompiled\VoxelForgeGpuFarStep27` bundle; the Step 27 control smoke loaded it as `executable_precompiled`. The legacy Step 28 executable loads the preserved top-level 20-entry `precompiled\*.cso` set and passed a smoke run. New builds leave that legacy set untouched. Step 29 loads its own 20-entry bundle, and the Step 29 agreement executable has its own copied 20-entry bundle. The Step 29 and preserved Step 28 shader files are byte-identical across all 20 entries; the warm-up marker aliases only after checking the warm-up bytecode.
+
+See [RUNNERS.md](RUNNERS.md) for build and race commands and the remaining legacy control behavior.
+
+## 3. Memory headroom and skirt route
+
+With GPU near skirts enabled, both final survival routes passed at 2,074 candidates. They reported zero surface overflow, panel overflow, and count-readback failures. The largest surface output was 18,153 of 19,456 vertices at `(2,-9,-4,lod1)`, slot 714. The far audit passed all 7,200 boundary surfaces and 10,976 connectors.
+
+| Route | Peak private | Peak viewer GPU-local | Peak combined |
+|---|---:|---:|---:|
+| Final default, auto | 4.10 GiB | 3,129 MiB | 7.00 GiB |
+| Final default, forced cold | 4.09 GiB | 3,128 MiB | 7.00 GiB |
+
+The compact output pool remains at 11,729,896 reserved vertices for 2,074 candidates, versus 67,960,832 under the old fixed per-tile allocation. The CPU near-skirt fallback reduced GPU-local peak from about 3.13 GiB to 2.39 GiB and combined peak from 7.00 GiB to 5.66 GiB. That saved about 0.74 GiB of GPU-local memory, but it created visible gaps, so it is not the default. The correct GPU route stays about 1 GiB below the per-process 8 GiB ceiling.
+
+## 4. Worker-count and hardware/WARP parity
+
+The Core worker clamp is now 1–16. The CPU reference passed at W1, W8, and W16 with the fixed hashes and 5,642/5,642 walkability:
+
+| Hash | Value |
+|---|---|
+| Density | `0xdb2991c73215af4c` |
+| Mesh | `0x8236c5edd7fc8e4f` |
+| Payload | `0x4c48fa75a543d58e` |
+| Topology | `0xbea22e76b34a4dfc` |
+
+Whole-near agreement passed all 960 tiles and 640 skirt audits on hardware and WARP. Sign differences, topology differences, protected-cell differences, skirt overflows, and skirt failures were all zero. Whole-far passed 1,114 tiles, 127,401 protected cells, and 353 thin-feature cells with zero sign, topology, protected, or thin-feature differences. The targeted thin tile `(-1,0,-1,lod3)` passed 35 protected and 18 thin-feature cell checks with zero differences.
+
+## 5. Numeric capture coverage and default routing
+
+The first ten-view matrix reproduced remote coverage holes with the CPU near-skirt fallback: `remote_yaw0/90/180/270` had 3,570 / 3,763 / 2,934 / 4,086 CPU-rock-to-GPU-background pixels. W8 reproduced the same counts, so the worker-count change was not the cause. The audited GPU near-skirt route had zero missing pixels in those views; I restored it as the default and made the runners pass it explicitly.
+
+The final ten full-residency CPU/GPU pairs were compared as numeric RGB arrays; no full-size capture was opened in an image viewer. Every view had zero CPU-rock-to-GPU-background pixels and zero GPU-rock-to-CPU-background pixels. See [step29_final_capture_comparison.md](step29_final_capture_comparison.md).

+
+The cached GPU speed goal remains open for the current adapter because the local driver route is cold and the marker misses. The correctness, W16 hashes, per-executable bytecode, and memory checks above are complete.
