## 2026-10-28: t88 phase 4 hardware verification and handoff (Codex)
- Reviewed the existing uncommitted Phase 4 changes rather than duplicating the implementation.
Grepped src/test/tools/docs for retired R canvas fields, CPU-light profiler fields, renderer
switches, smoothPace and thread callers. Retained cell.js/objects.js and test light oracles.
Cleanup against committed Phase 3: 23 code lines removed, 14 added (net -9). No further
source deletion or simulation change. TESTING now also correctly describes fixed render scale 1.
- Fresh NVIDIA WebGPU play-through passed: 122.779 s, 7,355 ticks (59.91/s), 16 helpers,
peak active 4. Flew, drilled 63 grains, vacuumed 27 sand, mouse-built 11 belts and 8 screws,
fed sand repeatedly and ran water/magma. No page/console errors, pause or stopped simulation.
Opened drill/flow/final screenshots: bot/terrain/UI intact, sand reaches the outlet pile,
water remains above cooled magma. Evidence: shots/t88-phase4/result.json and PNGs;
/tmp/t88-live.py and /tmp/t88-phase4-live-current.txt. Sandbox adapter assertion failed
before gameplay; host-GPU retry passed.

Final factory drawWorld 10.72x and CPU p50 3.75x faster than baseline. Smooth factory
zoom-2 CPU p50: 34.71 baseline -> 14.5 after 2c -> 10.60 after 2d -> 9.59 after 3 ->
9.54 final (earlier smooth 2a/2b figures unrecorded). Phase 4 timing differences are run
variation; no claimed Phase 4 speedup over 3.
- Polling retained. The main thread already overlaps its batch with helpers; the next pass
and serial work need completed outputs. waitAsync exists in this Chrome, but a safe use
propagates through chunkPasses, simMove/heatPass, simTick/frame and guards input/save/render
from in-flight shared writes. No cheap safe overlap or measured gain established.
API behaviour verified against [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Atomics/waitAsync)
and [ECMAScript](https://tc39.es/ecma262/multipage/structured-data.html#sec-atomics.waitasync).
- Recommendation: YES to a separate whole-simulation-worker project; not implemented.
Fresh auxiliary /tmp/t88-orchestration.py runs (factory/pixel/2 and heat/smooth/2, 599 ticks
each) measured dispatch/decode/merge at 0.565/0.587 ms/tick, local batch 1.099/1.316,
polling 0.485/0.543. Dispatch/decode/merge is 0.573/0.592 ms per sampled frame.
These wrapped measurements are separate from the unwrapped matrix.
Final live simulation occupies 2.09-2.74 ms/frame at p50; moving ownership could free
about 2-3 ms of main-thread time before message/snapshot costs. No fps gain expected on
these already-60-fps scenes. Worst zoom-2 CPU p95 11.127 leaves 5.540 ms of 16.667;
p99 12.614 leaves 4.052 ms. Benefit: responsiveness and headroom as factories grow.
Cost: command messages for flight/drill/vacuum/build/interact, undo/blueprints/dev console;
worker ownership of generation/load/save/export/pause/step; coherent published state for
GPU/rare-cell rendering, HUD/bag/economy, hover/minimap; integration with the helper pool.
Rendering must never read a world mid-write. Command determinism, input latency and save
consistency need separate tests.
- Map regenerated; TESTING already documents the tool cleanup. Profiler checks passed (headers, quantiles, comparison, deterministic simulation,
pixel/smooth image parity); both readout screenshots inspected. Final
`python3 test/run_all.py --browser` exited 0, ALL PASSED: 32 headless suites, gameplay
361, smooth 28, console 18, capabilities 7, GPU 12, golden 28, light 71, Firefox 2 checks.
Output: /tmp/t88-phase4-tests-current.txt. Suite summaries match the prior refresh except
timings. Map, diff check and kandown doctor passed. Phase 4 complete; t88 remains Review.
Files: retained render/{setup,cell,world,gpu/draw,gpu/textures}, tools/{perf.py,
perf-measure.js,perf-after-t88.json}, TESTING/PROJECT_MAP/agent-log and t88 tracking.
No commit; DESIGN and owner's Context untouched. Owner review remains.
## 2026-10-28: t88 phase 4 fresh live run, profile and review (Codex)
- Found the earlier uncommitted Phase 4 work and reviewed it rather than adding another
implementation. Whole-tree src/test/tools/docs searches confirm removed Canvas2D backing
stores and CPU-light profiler fields have no remaining live consumers. Retained cell.js,
objects.js, GPU lighting grid, settings and test light oracle. Cleanup versus 7468d00 is
23 code lines removed, 14 added, net -9; no simulation changes or further source edits.
- Rebuilt and repeated the real-GPU live check with /tmp/t88-live.py: 122.807 seconds,
7,356 ticks (59.90/s), 16 helpers, active peak 4, no page/console errors, pause or stopped
simulation. Flew with keys, drilled 63 grains, vacuumed 27 sand, mouse-built 11 belts and
8 screws, repeatedly fed sand alongside water/magma. Inspected all four screenshots under
shots/t88-phase4/: intact bot/terrain/UI, sand crosses the line and piles beyond the outlet,
water/magma reacts and cools. No abnormal stuck behavior found. Sandbox GPU assertion
failed before play began; host-GPU retry passed.
- Fresh full default `python3 tools/perf.py --compare tools/perf-baseline.json --json
tools/perf-after-t88.json` exited 0 in 216.0 seconds. NVIDIA Blackwell / RTX 5070 setup,
Chromium 156, 24 cores, 1920x1080 / 2048x1024. All 30 views, full/off lighting and 12 live
runs; source fingerprint verified and original baseline byte-equal to HEAD.
Settled/factory/heat sim: 1.983/2.442/2.506 ms/tick, 1.87x/1.50x/1.97x baseline.
Polling: 0.376/0.404/0.396; compute excluding polling: 1.607/2.038/2.110 ms/tick.
Every live run holds 60 fps; 0/7,139 sampled CPU work durations or frame intervals >16.7 ms.
CPU frame p50/p95, ms (zoom 2 / zoom 6):
| Scene | Pixel | Smooth |
|---|---|---|
| settled | 7.04/8.27 / 2.93/4.12 | 8.42/9.79 / 2.99/4.09 |

| heat | 8.46/9.81 / 4.80/5.92 | 9.90/11.01 / 5.06/6.18 |
- Phase history, factory/pixel/zoom 2, ms; historical columns from the entries below:
| Metric | Baseline | After 2a | After 2b | After 2d | After 3 | Final 4 |

| sim/tick | 3.657 | unrecorded | unrecorded | 4.200 | 2.495 | 2.442 |
Final factory drawWorld 9.91x and CPU p50 3.73x faster than baseline. Smooth factory
zoom-2 CPU p50: 34.71 baseline -> 14.5 after 2c -> 10.60 after 2d -> 9.59 after 3 ->
9.58 final (2a/2b smooth not recorded). No claimed Phase 4 speedup; variation from Phase 3.
- Polling retained after tracing threadPass/threadWait and their callers. Main-thread chunk
work already overlaps helpers; later passes/serial work need completed outputs. A safe
waitAsync change reaches chunkPasses, simMove/heatPass, simTick/frame and UI/save/render
access to in-flight arrays. No cheap safe overlap or measured gain established. API semantics
rechecked against [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Atomics/waitAsync)
and [ECMAScript](https://tc39.es/ecma262/multipage/structured-data.html#sec-atomics.waitasync).
- Recommendation: YES, as a separate whole-simulation-worker project; not implemented.
Fresh auxiliary /tmp/t88-orchestration.py runs (factory/pixel/2 and heat/smooth/2, 599 ticks
each) measure dispatch/decode/merge at 0.56-0.58 ms/tick, local batch 1.15-1.30, polling
0.49-0.55. These wrapped runs are separate from the unwrapped final profile above.
Final live sim p50 occupies 2.13-2.63 ms/frame. Expected main-thread recovery about 2-3 ms
before message/snapshot costs; no expected fps increase in these already-60-fps scenes.
Worst zoom-2 CPU p95 11.014 leaves 5.653 ms of 16.667; p99 12.103 leaves 4.564 ms.
Cost: command messages for flight/drill/vacuum/build/interact, undo/blueprints/dev console;
worker ownership of generation/load/save/export/pause/step; coherent GPU/rare-cell rendering,
HUD/bag/economy, hover and minimap snapshots; integration with the helper pool. Deterministic
command order, input latency and save/snapshot consistency need their own verification.
- Verification refresh complete: tools/test_perf.py exited 0 (headers, summaries, determinism
and both-look pixel parity); both readout screenshots inspected. Final
`python3 test/run_all.py --browser` exited 0, ALL PASSED: 32 headless suites; gameplay 361,
smooth 28, console 18, capabilities 7, GPU 12, golden 28, light 71, Firefox 2 checks.
/tmp/t88-phase4-refresh-tests.txt matches the prior full-suite summary except timings.
Current src matches the refresh-start snapshot and saved profile fingerprint. Map, diff
check and kandown doctor passed. Phase 4 checklist complete; t88 remains in Review.
tools/map.py regenerated PROJECT_MAP; existing TESTING changes cover the retired fields and
renderer/tool options. Files retained: render/{setup,cell,world,gpu/draw,gpu/textures},
tools/{perf.py,perf-measure.js,perf-after-t88.json}, TESTING/PROJECT_MAP/agent-log and t88.
No commit; DESIGN and owner's Context untouched. Owner visual review remains.
## 2026-10-28: t88 phase 4 final verification (Codex)
- Resumed the existing Phase 4 changes and checked their diff, live-run driver/results and
screenshots. The completed 122.8-second real-GPU play-through recorded 7,355 ticks
(59.90/s), flying, 63 grains drilled, 23 sand vacuumed, 11 belts and 8 screws built with
mouse drags, sand feeding and water/magma. No errors, pause or stopped simulation.
Opened 01-drill.png and 03-flow.png again: bot, terrain and UI intact; sand crosses the
line and piles beyond its outlet. This evidence was retained, not rerun during resume.
Driver /tmp/t88-live.py; screenshots/raw results in shots/t88-phase4/.
- Fresh full default profile on the host GPU: `python3 tools/perf.py --compare
tools/perf-baseline.json --json tools/perf-after-t88.json`, exit 0, 215.5 seconds.
The JSON source fingerprint matches the current src/tools; baseline bytes match HEAD.
NVIDIA Blackwell, 24 cores, Chromium 156, 1920x1080 / 2048x1024, all 30 views and
12 live runs. This fresh run replaces the initial Phase 4 profile.
settled: 1.913 ms/tick (1.94x baseline), polling 0.392, main compute 1.520; 16 helpers, peak active 4.
factory: 2.386 ms/tick (1.53x baseline), polling 0.406, main compute 1.980; 16 helpers, peak active 5.
heat: 2.695 ms/tick (1.83x baseline), polling 0.420, main compute 2.275; 16 helpers, peak active 5.
All 7,137 sampled frames: zero CPU work or intervals >16.7 ms; every live run 60.00 fps.
CPU frame p50/p95, ms (zoom 2 / zoom 6):
| Scene | Pixel | Smooth |
|---|---|---|
| settled | 7.03/8.50 / 2.76/3.89 | 8.47/9.87 / 2.93/4.08 |
| factory | 8.38/9.82 / 5.00/6.13 | 9.54/10.77 / 4.98/6.08 |
| heat | 8.80/10.17 / 4.84/5.84 | 9.92/11.27 / 5.07/6.07 |
- Phase history, factory/pixel/zoom 2 (ms; earlier columns from the entries below):
| Metric | Baseline | After 2a | After 2b | After 2d | After 3 | Final 4 |
|---|---:|---:|---:|---:|---:|---:|
| drawWorld | 24.55 | 9.98 | 6.79 | 2.53 | 2.44 | 2.41 |
| CPU frame p50 | 31.70 | 15.40 | 10.25 | 9.28 | 8.48 | 8.38 |
| sim/tick | 3.657 | unrecorded | unrecorded | 4.200 | 2.495 | 2.386 |
Final factory drawWorld 10.20x and CPU frame p50 3.78x faster than baseline.
Smooth factory zoom-2 CPU p50: baseline 34.71 -> 2c 14.5 -> 2d 10.60 -> 3 9.59
-> final 9.54 ms (2a/2b smooth figures unrecorded).
Phase 4 itself has no claimed speedup over 3; differences are run variation.
- Cleanup reviewed with whole-tree src/test/tools/docs references: 23 code lines removed,
14 added (net -9). Unused Canvas2D backing objects and CPU-light profiler fields removed;
cell.js/objects.js, GPU light grid, live flags and test helpers retained. Updated TESTING's
tool/renderer descriptions, regenerated PROJECT_MAP. No simulation code changed.
- Polling retained: no cheap safe overlap found. The existing main-thread batch already
overlaps helper work; subsequent serial work needs its result. Async wait would require
changes through chunkPasses/simMove/heatPass/simTick/frame and shared-state guards for
input, save and render. Non-blocking semantics confirmed against
[MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Atomics/waitAsync)
and [ECMAScript](https://tc39.es/ecma262/multipage/structured-data.html#sec-atomics.waitasync).
- Recommendation: YES to a separate whole-simulation-worker project. Auxiliary instrumentation
(/tmp/t88-orchestration.py and .json, factory/pixel/2 and heat/smooth/2, 599 ticks each)
measured dispatch/decode/merge at 0.55-0.60 ms/tick, local batch 1.11-1.35 and polling
0.50-0.60. These are wrapped auxiliary runs, not the unwrapped final real-loop measurements.
Current final live sim p50 is 2.09-2.69 ms/frame; estimate 2-3 ms main-thread budget recovered
before message/snapshot costs, not an fps increase in these already-60-fps scenes.
No sampled frames miss 16.7 ms. Worst zoom-2 CPU p95 11.27 leaves 5.40 ms;
p99 12.64 leaves 4.02 ms against 16.667. Expected benefit is headroom and responsiveness.
Cost: command messages for flight/drill/vacuum/build/interact, undo/blueprints/dev console;
worldgen/load/save/export/pause/step ownership; coherent render/rare-cell/HUD/bag/economy/
hover/minimap snapshots while the next tick writes elsewhere; integrate the helper pool.
Deterministic command order, save consistency and input latency need verification.
No whole-simulation worker implemented.
- tools/test_perf.py exited 0: headers, summaries/comparison, deterministic sim and both-look
image parity; inspected both new perf-readout screenshots. Initial sandboxed profiler failed
to acquire WebGPU; host-GPU retry passed. Final `python3 test/run_all.py --browser`
exited 0, ALL PASSED: 32 headless suites; gameplay 361, smooth 28, console 18,
capabilities 7, GPU 12, golden 28, light 71, Firefox 2 checks. Full output:
/tmp/t88-phase4-verified-tests.txt. Map, diff check and kandown doctor passed.
t88 moved to Review; owner visual review and Claude commit remain.
- Files: existing Phase 4 render/setup/cell/world and GPU draw/textures, perf.py/perf-measure.js/
perf-after-t88.json, TESTING/PROJECT_MAP/agent-log and t88 tracking. No commit, no DESIGN edit;
owner's Context unchanged. Owner visual review remains.
