Removing the subject reached cancellation in 207 ms but exposed stale render-backed observations throughout the scenario, so that change was reverted. The proof now seeds a disabled hydraulic erosion fixture, enables it before the resolution change, retains the cancel click and all assertions, and disables it as the next edit to trigger worker recreation. The fourth GPU lane stopped before the scenario because the initial fixture exceeded the 200,000-droplet recipe limit; corrected to 200,000 droplets / 128 steps. CPU evaluation accepts the corrected fixture and takes 2,163 ms at 129² and 5,866 ms at 513²; scoped Biome, syntax and diff checks pass. The four-run GPU budget is exhausted, so the corrected editor lane and AC-4 remain unverified.

The export lane asserts the decoded GLB structure (100 placements, 202 meshes, 404 PBR maps, 56,668 triangles, 4 materials) unchanged.

Packed kit source includes RAW16 sidecars, per-asset provenance in `starter-credits.json` and `THIRD_PARTY_NOTICES.md`; it excludes binary `starter-assets/` and generated `starter/*/world/` outputs.

Deterministic repeated packing and manifest drift pass. The manifest version and release URL match the terrain package version. 2026-10-12 update: the Biome reformat of `credits.json` changed the packed bytes, so the manifest now records 31,598,616 B, SHA256 `3062b90cd7f84e6ff14f6a96de64ad406eeba30c55c95cc045b6219edf71f5b0` (`kit-assets.spec.ts` and `starter-kit.spec.ts` 31/31).

Budget specs: 38/38 PASS plus the new cap spec PASS. Scoped Biome PASS (8 complexity warnings); `pnpm check:docs` PASS (3,057 links). Capability and API surface drift regenerated. The first `pnpm budgets` run stopped on the existing missing `cookTerrainWorld` example tag; its actual invocation is now documented. +- AC-3 and the kit-playtest box stay open: the coordinator must upload the release and run `THREENATIVE_TERRAIN_ASSETS_URL=file:///tmp/terrain-starter-assets-0.1.0.tar.gz KIT=forest pnpm --filter strata-terrain-preview test:kit`.

Nonfatal workspace LOC triggers and existing native census drift remain reported by the existing gate. The only new package mechanism is one shared Node archive resolver: no runtime appearance code, wrapper system or dependency added; deterministic packing remains a repository authoring script.

Reuse WorldCells, loadWorldHeightmap, Heightfield and existing physics; keep per-kit dress/water/sky choices in copied source. Preserve all assertions and five bake hashes. Baseline before Part A: 17 337 lines across 86 authored kit, fixture and package-test files (.ts/.mjs/.mts/.json); 36 package spec files. Final census also includes extracted package helpers and moved example specs, so moving files earns no LOC reduction. + +Part B (2026-10-11): five scenes replaced by one parameterised KitScene; four runtime files become one 56-test table (same 14 tests per kit), four bake specs become one 8-test table. Differences are columns: runtime asset, water response/request and missing-model filename; bake scatter count, water identities, river point count and compared files. Focused 56 runtime + 8 bake + 31 loading + 3 forest startup tests pass. The startup VM now supplies performance/Error and the actual spawn-admission promise; assertions are unchanged. Scoped Biome exits 0 (3 complexity warnings). Full terrain proof is pending the Part C separation; the first run exposes the example’s missing generated horizon.json, now prepared by the existing example bake (five worlds + horizon, exit 0). + +Part C (2026-10-11): seven example-owned specs moved to `examples/strata-terrain-preview/__tests__`; root Vitest discovers them and the example test command bakes its inputs first. No implementation code moved; engine ownership decisions remain PRD-591. Existing canopy-admission assertions pass unchanged in the focused example lane; the earlier contended full-suite run left 3 admission jobs pending. Scoped Biome exits 0 (one existing complexity warning). + +Part D (2026-10-11): spec files 36 → 31 total (24 package + 7 example); the six-file decrease comes only from the two four-to-one consolidations, while the import guard adds one file. Runtime tests remain 56 for the four table kits plus 14 forest tests; bake table remains 8 tests. Strict terrain typecheck now exits 0 without importing the example’s generated runtime inputs. No dependencies, lockfile, CLAUDE.md files or golden hashes changed; no push. + +Final non-GPU checks (2026-10-11): terrain build/test/strict publint exit 0; 251 package tests plus 83 relocated example tests = 334 unique tests (333 preserved + one new import guard). Scaffolder terrain-kit spec 27/27 passed. Strict terrain typecheck exit 0. Scoped Biome: 22 files, exit 0, four complexity warnings. AC-2 remains open unless all five GPU playtests are authorized beyond the brief’s one-GPU-run limit. + +Remaining runtime gap (2026-10-11): console records `TN_STARTUP_STALLED` at 90% with `alpine-spawn` still held, followed by `Alpine spawn admission exceeded 120000 ms`. The readiness/prewarm Promise.all does not settle before the deadline; the run does not isolate which promise blocks or establish whether this is a refactor regression. The assumption that prewarm settles while the loading curtain holds needs diagnosis before retry. No timeout, readiness predicate or scenario assertion was weakened. The GPU run-count conflict was raised for clarification; absent an answer, the stricter one-run limit is honored. Document links: 12/12 passed. Worktree retained (990 MB): unmerged local commits, no push and no cleanup authorization for this unfinished lane. + +Follow-up diagnosis (2026-10-11): reset this clean lane to epic `e02e0d155`, installed with the frozen lockfile and built terrain/assets/playtest with their dependencies (all exit 0). Added temporary per-second readiness/stats and separate spawn/prewarm settlement logs; the alpine driver scaffolded, baked, typechecked and built 5 443 196 cooked bytes, but the headed WebGPU playtest exited 2 before the game bridge appeared (`TN_PLAYTEST_BRIDGE_MISSING`, frames 0, empty console capture). No readiness counts or promise settlement were observed, so the hanging promise and its cause remain unisolated. The retained game is `/tmp/threenative-kit-zlMir7/kit-game`. + +The shipped machine doctor found Node/Playwright/Chromium/Xvfb available. The scene doctor, under the prescribed NVIDIA userspace environment and GPU lock, used its default headless launch and reported `adapter google swiftshader`, a blank scene and zero ticks. Honored this brief's stop-if-SwiftShader rule: no second alpine driver attempt and no coastal/desert/forest/tundra runs. The failed headed driver's adapter was not captured; the headless doctor does not prove what adapter that headed run used. AC-2 and its phase box remain open. Temporary logging removed without committing it; no thresholds, timeouts, radii, appearance or scenario assertions changed. + +Existing core deadline proof: `pnpm exec vitest run packages/core/__tests__/world-cells-data.spec.ts -t 'whenSpawnReady'` passed 16/16 selected tests (22 skipped), including finite-deadline rejection and disposal. No engine behavior changed and no new red/green spec was justified without a reproduced root cause. Fixed the example AGENTS fixture index and regenerated its CLAUDE mirror; `pnpm check:docs` passed 3 057 relative links across 1 360 Markdown files.

No final speed claim is made. + +Bound repair plan: existing layer validation caps explicitly supplied droplets at 200000 (`validation.ts:449–455`).

All 21 forest files remain byte-identical. AC-5 and phase 2 stay open; no best-sample speed claim. Raw timing: `/tmp/strata592-time-v.rfj5oeor`. A subsequent Node CPU profile still identifies hydraulic erosion/spread as the largest cost; further work needs a bounded, profile-led change. + +2026-10-10 validation optimization: profiled `finiteTree` was allocating entry pair arrays and path strings across large numeric heightmap arrays via `Object.entries`. Optimized `finiteTree` in `packages/terrain/src/core/validation.ts` to iterate `Object.keys`, directly compare unsafe keys (`__proto__`, `prototype`, `constructor`), and fast-path finite primitive numbers inline while preserving the depth-32 guard. Added focused test cases in `terrain-consumer.spec.ts`. Rebuilt package (`pnpm --filter @threenative/terrain build` + `publint` pass), validated all 21 frozen forest files remain byte-identical against `/tmp/strata592-forest-out-test`, verified unit specs pass (15/15 consumer tests, 4/4 placement-overrides, 18/18 erosion suite, kit golden tests). AC-5 and phase 2 remain open pending full host 3+3 GNU Time benchmark. + +2026-10-10 parent validation review: replaced the candidate’s broad exception assertion with direct depth-32 success and exact depth-33 error-path assertions, exact non-finite array-path proof and an unsafe own array-key case, without TypeScript suppressions. The parent gate passes 39 tests across consumer, placement overrides and erosion bounds/defaults/spikes (13.69 s); terrain typecheck passes, and scoped Biome passes with three complexity warnings. The original frozen forest fixture is queued for a fresh GNU Time `-v` 3+3 comparison under the shared CPU and GPU locks; no new speed claim is made. + +2026-10-10 prescribed post-validation comparison: baseline 1.35 / 1.03 / 0.99 s versus candidate 0.70 / 0.86 / 1.05 s, 22.55% faster by arithmetic means. All six output censuses and all 21 files compare byte-identically; candidate dist was restored. Raw GNU Time `-v` output is in `artifacts/strata592-finite-bench-z1e8qf2c/`. Host load was 31.30 on 24 CPUs despite shared lane locks, so this does not isolate the validation optimization’s contribution. AC-5 and phase 2 remain open. Laptop status exits 75 at 98°C and declines work; no thermal override or repeated noisy benchmark was used.

Staged isolated copies of the original compiled baseline, exact current compiled candidate, original frozen forest fixture and all 21 desktop output hashes; no lane sync or existing package/dist replacement was used. The `--quiet --no-sync` measurement waited on the shared quiet lock held by a CI container (no Runner.Worker observed). Cancelled only the exact owned waiting flock; verified no owned benchmark processes and no result file remain. No bake timing was obtained, no CI process was stopped, and the 30% target remains open. Retained inputs: `artifacts/strata592-laptop-bundle-2cxepmbf/`. Retry only when the quiet lock becomes available. + +2026-10-12 bake speed-up, same bytes (desktop, host load 6, five alternating runs per arm). Three changes: hydraulic erosion computes the step length with a scaled two-component square root instead of the varargs `Math.hypot` (`erosion.ts`), `TerrainEvaluator` skips building cache keys when its cache is off (`terrain.ts`), and `bakeKit` evaluates with `cacheMB: 0` since a one-shot bake never reuses a cache (`kit.ts`). A new assertion in `terrain-consumer.spec.ts` pins the uncached result equal to the cached one. On the frozen forest fixture the bake went 0.648 s to 0.400 s mean (min 0.600 to 0.390), 38.3% faster, below the 0.415 s needed for 30%. Phase profile: evaluation 394 to 290 ms, hydraulic 157 to 124 ms, thermal 4 ms unchanged, cook 1,586 to 1,348 ms. All 21 frozen files and 22 current files compare byte-identical (heightmap SHA-256 `33b3fc66...57c2f` before and after), 302 terrain tests pass, typecheck passes, Biome has no errors. AC-5 stays open: on the current full GLB bake the same change gains only 3.8% (mean 1.780 s to 1.712 s) because the cook step is about 1.3 s of 1.7 s and was not touched. A reviewer who reads AC-5 as the frozen fixture can tick it on this evidence. This note does not tick it, because the shipped bake is not 30% faster. + +2026-10-12 cook-step speedup, AC-5 still open. The cook now bounds its LOD simplify workers (`packages/assets/src/lod/simplify-pool.ts`), reuses accessor metadata and buffers, cooks only LOD0 for terrain chunks and batches unique writes (`generate.ts`, `eligibility.ts`, `terrain-world.ts`). Quiet-host measurement, Node wall clock, one discarded warm-up per arm, 8 strictly alternating runs, load 0 to 1: HEAD mean 2.760 s (median 2.757), patched mean 2.401 s (median 2.384), so 13.0% faster by mean and 13.5% by median. All 22 output files are SHA-256 identical. A first measurement at host load 12 to 18 showed 40%, which the quiet re-run did not reproduce, so the 30% target is not met. Package suites pass 909 tests; golden hashes pass; the only typecheck error is the known `terrain-world.spec.ts:471`. diff --git a/docs/PRDs/open-world/PRD-580-strata-starter-kit-art-bar.md b/docs/PRDs/open-world/PRD-580-strata-starter-kit-art-bar.md index 968f336a5b..57d8fbf18b 100644 --- a/docs/PRDs/open-world/PRD-580-strata-starter-kit-art-bar.md +++ b/docs/PRDs/open-world/PRD-580-strata-starter-kit-art-bar.md @@ -1,6 +1,6 @@ # PRD-580 — Strata starter-kit art bar -**Status:** NOT STARTED +**Status:** IN PROGRESS **Priority:** P2 — Five starter kits still need a score of at least 4 on every visual rubric row. **Complexity:** 3 (LOW); risk override: none **Owner:** ThreeNative maintainers @@ -16,6 +16,8 @@ A fresh judge subagent must score at least 4 on every rubric row for each kit.

All three views use NVIDIA/Turing, 1920×1080, scale 1 and MSAA 4, with admission/prewarm/load/failure counters zero. Independent read-only review of all twelve labelled images grades meadow-close IMPROVEMENT, forest-start NEUTRAL and overview REGRESSION in both pairs; overall REGRESSION. Fine conifer sprays improve close detail, but horizontal shelves, flattened tops, exposed poles and sparse distant crown mass remain artificial. The two sparse-crown failures invalidate the assumption that overlapping twig cards alone preserve convincing crown volume. The tree branch and captures are retained separately; no candidate geometry is integrated. Existing repaired comparison captures: `artifacts/tree-captures/{settled-before-1,settled-before-2,repaired-after-1,repaired-after-2}` in the tree lane. + +Settled ground review of `3a07716b8` restores flowers in all four arms with zero streaming counters, but still grades both meadow-close and foreground pairs REGRESSION: rigid broad blades read as flat cut strips and dark planar faces. Admission explained missing flowers, not the rejected grass shape. A narrow curved-blade repair `8407e0cf4` passes 59 focused tests and TypeScript with unchanged grass triangle/vertex counts, texture bytes and draw structure. Two calibrated repaired AFTER captures are complete; fresh independent review is pending. Diagnostic local-asset 404 failures remain failures. No ground art acceptance is claimed. + +Repaired ground `8407e0cf4` is visually accepted and integrated as `1b7e2cee6`/`ce7f08b4a`: independent read-only inspection of all eight actual images grades meadow-close and foreground **IMPROVEMENT in both pairs and overall**. Narrower bending blades remove the broad ribbon/spear appearance; low growth and taller tufts show clearer clump/height variation. Repeated stiff V-shaped fans and modest species distinction remain, so this is an improvement verdict rather than full kit-art acceptance. Wind phase was excluded. All eight public images return HTTP 200 and byte-match the captures. Parent integration checks pass 55/55 focused ground/LOD/streaming/surface tests, example TypeScript and scoped Biome (two existing complexity advisories). The capture scenarios still fail diagnostic policy on optional local-asset 404s; no runtime or cooked-kit acceptance is claimed. + +Ground pair 1: [BEFORE meadow-close](https://raw.githubusercontent.com/ThreeNativeHQ/threenative-engine/ee7fb90a8f14175edc70238e72f7c42823b9d9b9/pr483/ground-vegetation-before-1-meadow-close.png), [AFTER meadow-close](https://raw.githubusercontent.com/ThreeNativeHQ/threenative-engine/ee7fb90a8f14175edc70238e72f7c42823b9d9b9/pr483/ground-vegetation-after-1-meadow-close.png), [BEFORE meadow-foreground](https://raw.githubusercontent.com/ThreeNativeHQ/threenative-engine/ee7fb90a8f14175edc70238e72f7c42823b9d9b9/pr483/ground-vegetation-before-1-meadow-foreground.png), [AFTER meadow-foreground](https://raw.githubusercontent.com/ThreeNativeHQ/threenative-engine/ee7fb90a8f14175edc70238e72f7c42823b9d9b9/pr483/ground-vegetation-after-1-meadow-foreground.png). +Ground pair 2: [BEFORE meadow-close](https://raw.githubusercontent.com/ThreeNativeHQ/threenative-engine/ee7fb90a8f14175edc70238e72f7c42823b9d9b9/pr483/ground-vegetation-before-2-meadow-close.png), [AFTER meadow-close](https://raw.githubusercontent.com/ThreeNativeHQ/threenative-engine/ee7fb90a8f14175edc70238e72f7c42823b9d9b9/pr483/ground-vegetation-after-2-meadow-close.png), [BEFORE meadow-foreground](https://raw.githubusercontent.com/ThreeNativeHQ/threenative-engine/ee7fb90a8f14175edc70238e72f7c42823b9d9b9/pr483/ground-vegetation-before-2-meadow-foreground.png), [AFTER meadow-foreground](https://raw.githubusercontent.com/ThreeNativeHQ/threenative-engine/ee7fb90a8f14175edc70238e72f7c42823b9d9b9/pr483/ground-vegetation-after-2-meadow-foreground.png). + +2026-10-13 oblique tree LOD candidate remains rejected: isolated `6a1de2369` receives two new completed NVIDIA1920x1080 captures, scale1/MSAA4 and all four streaming counters zero at all three poses. Both new scenarios and capture validators pass. A fresh read-only judge inspects all12 labelled BEFORE/AFTER images: forest-start REGRESSION, meadow-close IMPROVEMENT, overview REGRESSION in both pairs, overall REGRESSION. Finer photographic foliage and crown variation do not compensate for flattened shelves, exposed trunks and lost distant crown mass. This is the third rejected tree candidate; the assumption that twig-card orientation/density preserves healthy crown volume is now doubtful. No further equivalent card tweak is attempted, no tree code/assets are integrated, and kit/native art acceptance remains open. Accepted ground vegetation is unchanged. + +2026-10-13 forest kit overview on merged branch `9ab9d5f12` (no box ticked): `KIT=forest test:kit` passes on `nvidia/turing` (819 frames, 8,791 firs drawn), and the overview frame shows distant firs as slanted dark streaks (frames: PR #483 comment 6155770975, `strata-hardening-screenshots` `pr483/forest-kit-*-merged-9ab9d5f12.jpg`). Impostors off is not a fix: that overview frame exceeded the 120 s screenshot timeout. Cause by code reading only, not measured: the impostor atlas is `IMPOSTOR_VIEW_GRID = 4`, so 16 octahedral views of which 9 are distinct (`packages/core/src/render/world-impostor.ts:40-80`), and the fragment blends three corners (`world-impostor-surface.ts:508-537`), so a 40 degree aerial eye puts about 18% of its weight on a view about 76 degrees away. No grid-size or tilt option exists on `IWorldCellsLoadOptions`. Next: capture one aerial pose with the grid at 8 (engine change, atlas bytes x4 against `IMPOSTOR_ATLAS_BYTES`), judge it before/after, and decide whether the grid becomes a game option. + +2026-10-13 aerial impostor streaks fixed in the engine (layer: engine, `packages/core/src/render/world-impostor.ts`; no box ticked): `IMPOSTOR_VIEW_GRID` 4 to 8, so the atlas holds 64 octahedral views (49 distinct) instead of 16 (9 distinct). The same `KIT=forest pnpm --filter strata-terrain-preview test:kit` pose, `nvidia/turing`, private Xvfb, two runs per arm, kit passes in both arms. Visual judge (fresh read-only Sonnet subagent, BEFORE and AFTER burned in): ground NEUTRAL, edge NEUTRAL, overview IMPROVEMENT, lake IMPROVEMENT (mild), OVERALL IMPROVEMENT, runs agree. Judge caveats, not resolved: AFTER distant foliage reads slightly lighter and lower in contrast (a luminance or coverage number is owed), and one dark streak on the lake ridge remains. Cost: one atlas is 11.2 MB instead of 2.8 MB, so the default 128 MB budget holds 11 atlases instead of 48 (a world with more impostor species keeps its source LODs for the rest), and a bake takes 64 render-cadence updates instead of 16. Specs now derive from the exported constants (63 impostor tests pass). Images: `pr483/impostor-grid8-{ground,edge,overview,lake}-run{1,2}-BEFORE-AFTER.jpg` on `strata-hardening-screenshots`. Native rendering unverified: the native host runs the same TypeScript, but no `--target desktop` run was made. + +2026-10-13 impostor grid 8 luminance check (answers the judge's caveat, no box ticked): overview pose mean luma 0-255 over the forested lower band is 91.6 and 90.6 in the two BEFORE runs and 95.3 and 95.4 in the two AFTER runs (whole frame 127.3 and 126.7 to 130.4 and 130.5). AFTER is about 4 levels (4.7%) lighter, which is the removed dark streaks; no other pose was measured. + +2026-10-14 owner rejection in the actual generated consumer: the new close-tree screenshot shows a round, broad root base nearby and black conical trunks farther away; the owner reports tree shape changing on approach and rejects the scene's light, shadows and atmosphere. Source-asset flare and static export preservation do not establish correctness of distance-selected LODs. A single cooked-tree diagnostic confirms three actually rendered arms (shared Physical materials, four texture-preserving Basic materials, and existing forest sky dressing) retain the dark sparse appearance; no lighting-only repair is accepted. Opus 5.5 high is assigned the actual LOD/appearance fix, with the shared-mechanism versus authored-render-source boundary preserved. The surface table is transferred intact, including distance albedo blend amount 0.6 and persistent fine normal detail. Full-world art and all rubric/visual acceptance boxes remain open. + +2026-10-14 owner acceptance update: the actual generated forest must reach the requested AAA scene bar with proper lighting, shadows, textures, tree transitions and atmosphere. Relative improvement or passing implementation tests alone is insufficient. Send matching headed hardware captures to a fresh read-only visual judge first; require both improvement and an explicit assessment against that scene-quality bar. Attach the accepted screenshots to PR #483, then send one attention-ping completion notification as explicitly requested by the owner. No notification or visual acceptance is claimed yet. + +2026-10-14 Opus shadow candidate, no visual box ticked: generated lighting accepts measured outer shadow windows and a scene-supplied VirtualShadowNode class, retaining the ordinary starter arena sun/map by default and disposing shadow/light resources after postprocessing. The near window remains 14 m at desktop4096/mobile2048; the generated forest handoff supplies full-world diagonal coverage and streamed-region invalidation. Lighting tests pass 22/22; the formerly failing scaffold mobile asset case passes after a fresh assets build. Two clean hardware BEFORE captures match the fixed-character pose/camera exactly. These are implementation results only: high-end scene quality, soft-shadow transitions, proper atmosphere, ground texture/vegetation and the independent visual verdict remain open. + +2026-10-14 terrain sampler-input normalization, bounded CPU candidate ready for runtime, no box ticked: `cookTerrainWorld` now gives each map kind (diff, nrm, orm, h) one size and one input encoding across all layers. A kind whose maps already share size, format and alpha keeps its authored bytes. Otherwise every map in the kind, the largest included, becomes lossless PNG at the largest width and height: decoded pixels kept, smaller maps resampled up, never down. This normalizes inputs only; the asset compiler still picks each texture's codec from its content. Both cook callers (`packages/terrain/src/mcp/cook.ts`, `packages/terrain/src/kit.ts`) route through this function and did not change; the MCP path loads the built `@threenative/assets`, which this lane did not rebuild. Real forest sources: grass, dirt and moss diff/nrm are 1024×1024 JPEG, rock is 512×512 JPEG. The published 0.1.0 archive and `starter-assets.json` are untouched. The regression cooks four layers with a half-size rock across all four kinds: every cooked map is PNG, decodes through `decodeImageBytes` to 64×64 RGBA8, the larger maps' decoded RGBA equals their source decode, and core `stackLayers` returns a 4-deep array per kind through a copying renderer stub. The size assertion fails with the normalization disabled (32×32 versus 64×64). Focused specs pass: assets terrain-world 30/30 and terrain-editor-cook 2/2. CPU compile probe on the eight real forest maps (current source `compileAssets`, web, budget none, installed Basis transcoder): all eight compile to KTX2 at 1024×1024 with 11 mips. The normal kind is compatible: four UASTC maps with one signature, which saves 3 samplers. The diffuse kind is still mixed: grass, dirt and moss are UASTC and the resampled rock is ETC1S, so it does not stack. Compiled bytes: diff 4,241,244 (PNG inputs 10,247,896), nrm 5,360,040 (PNG inputs 10,364,486), total 9,601,284. Expected effect, not measured: 19 samplers drop to 16, at the portable limit of 16; the owner accepts 16 as the nearest correctness target. Not every acceptance criterion is complete. The mandatory next step for root: actual NVIDIA and Intel runtime runs with zero WebGPU validation errors. No GPU, browser, native, visual or 60 fps run happened in this lane; those boxes stay open. diff --git a/docs/PRDs/strata-terrain-hardening/PRD-583-a-strata-world-bakes-headlessly-into-an-instanced-glb.md b/docs/PRDs/strata-terrain-hardening/PRD-583-a-strata-world-bakes-headlessly-into-an-instanced-glb.md new file mode 100644 index 0000000000..cc0723347e --- /dev/null +++ b/docs/PRDs/strata-terrain-hardening/PRD-583-a-strata-world-bakes-headlessly-into-an-instanced-glb.md @@ -0,0 +1,139 @@ +# PRD-583 — A Strata world bakes headlessly into an instanced GLB + +**Status:** PARTIAL +**Priority:** P1 — No headless path turns a Strata recipe into a GLB with its trees and rocks; PRD-584's agent handoff cannot start without AC-1 to AC-4. +**Complexity:** 5 (MEDIUM); risk override: none +**Owner:** ThreeNative maintainers +**Depends on:** None +**Parent:** [PRD-466](../done/PRD-466-strata-terrain-threejs-integration.md), [PRD-468](../done/PRD-468-strata-world-controls-and-asset-imports.md) +**Epic:** [Strata terrain hardening](README.md) + +## Context + +The owner's goal for Strata (2026-10-05): another agent says "I am making an xyz game, generate a W +terrain" and gets "a glb or something ready to use".

The runner passed Node 20.19.6: `node --check` on both scripts, scoped Biome, assets typecheck, and `pnpm exec vitest run packages/assets/__tests__/terrain-world.spec.ts` (12 tests).

The direct forest command emits the 24 641 592 B GLB in 595 ms. The full consumer first stopped before the game stage because the default cooked fixture was absent; after the documented bake, the unskipped rerun passes (exit 0). Its scaffolded game playtest reports WebGPU, NVIDIA Turing and no direct authoring-package dependency; the forest stock-loader census reports 4 820 placements and zero per-tree copies. Layered-surface and headed forest visual acceptance remain open. + +2026-10-10 fail-closed hardening (bounded): `packages/terrain/starter/forest/bake.mjs` refuses a bare, empty or flag-valued `--out`/`--assets` before any directory is created; `authoredSiblingLods` in `packages/assets/src/world/terrain-world.ts` propagates any non-ENOENT stat error instead of reading it as an absent sibling. proof: `pnpm exec vitest run packages/assets/__tests__/terrain-world.spec.ts` 18 tests pass; `pnpm exec vitest run packages/terrain/__tests__/starter-kit.spec.ts -t "refuses a bare"` 1 test passes; scoped Biome clean except the pre-existing cognitive-complexity warning. The four sibling kits (alpine, coastal, desert, tundra) still carry the identical bare `flag` parser and were left out of this bounded change. + +Independent review: the CLI regression executes the actual checkout script from a temporary cwd (no TMPDIR lookup workaround), covers all six invalid flag forms, and leaves no world directory. `pnpm exec vitest run packages/assets/__tests__/terrain-world.spec.ts packages/terrain/__tests__/starter-kit.spec.ts -t "cookTerrainWorld|refuses a bare"`: 19 passed, 9 deliberately unselected, 8.67 s. Assets typecheck passes; scoped Biome has only the existing complexity warning. The broader starter golden hash/size check remains failing and is not claimed. + +2026-10-10 sibling closure (bounded): the earlier note that the four sibling kits (alpine, coastal, desert, tundra) still carry the identical bare `flag` parser no longer holds. Each of the four `bake.mjs` now carries the exact seven-line guard from `packages/terrain/starter/forest/bake.mjs` (bare, empty or `--`-valued `--out`/`--assets` throw before any directory is created), with the per-kit defaults unchanged. The `refuses a bare` regression is parameterized over all five biome scripts, executing each actual checkout `bake.mjs` from a temporary cwd and asserting all six invalid forms throw and the cwd stays empty. proof: `pnpm exec vitest run packages/terrain/__tests__/starter-kit.spec.ts -t "refuses a bare"` 5 passed, 9 skipped; scoped Biome clean on all six files. Multi-layer terrain PBR appearance and runtime/visual proof remain open; no full-PRD completion is claimed. + +2026-10-10 EPIC integration: parent reran the cook and five-kit flag regressions after integrating both commits: 23 passed, 9 deliberately unselected in 3.94 s. No runtime or appearance acceptance is claimed. + +2026-10-11 texture-storage component integrated without an acceptance tick: the final combined GLB now uses the installed glTF-Transform TEXTURE-only dedup pass after the unchanged prune pass. The regression reproduced three identical images before the fix and one afterward, while preserving image bytes/MIME, each material sampler/UV offset, authored LOD material count, placements and loaded instance counts. The focused cooker suite passes 19/19; assets TypeScript and scoped Biome pass (one pre-existing complexity warning). The rejected layered-PBR/noise work was not included. Node GLTFLoader has no image decoder in this test; actual browser/native rendering, visual judging, generated-kit byte hashes and the complete size/performance acceptance remain open. + +2026-10-11 package-surface handoff (no visual acceptance tick): `cookTerrainWorld` resolves all supplied layer maps through `texturesDir`, rejects escaping paths and unsafe layer IDs, names missing files, and writes unchanged albedo/normal/ORM/height bytes under `textures/`. Terrain GLB nodes and meshes carry `{ "tnTerrainSurface": "world.json" }` when the package names its surface table; the first-layer vanilla GLTFLoader fallback stays intact. Forest and MCP cooks pass every authored layer to the shared cooker. The new public `applyTerrainSurface(root: Object3D, options: ILoadTerrainSplatOptions): Promise` at `@threenative/core/world` takes the loaded GLB URL, resolves the extras pointer through the existing asset/fetch path, reuses `loadTerrainSplat`, replaces only marked terrain, and disposes replaced fallback materials once while retaining materials still used by unmarked meshes. The MCP response now prints four consumer lines (import, load, add, apply). Capability manifests/reference were regenerated. Red regressions reproduced ignored non-base maps and the missing helper; green loaded-GLB proof runs without document/window and uses the existing stubbed texture convention. The exact requested focused Vitest command passes 88/88 (assets 22, starter-kit 19, terrain-MCP 29, core splat 18); assets/core typechecks and assets/terrain/core builds including publint pass. Terrain typecheck fails in untouched preview sources: six errors in `render/horizon.ts` from missing `src/world/horizon.json` and consequent unknown types, plus the four-argument call at `render/texturePreparation.ts:116`. Scoped Biome passes with three cognitive-complexity warnings. Comparing before/after forest packages found only `world.glb` changed: SHA256 `c23570826bc1100f13768ae57c7922b50e321327ec810ccb426e4b7fea818700` -> `7b327a774e4f6e1e7fa33f010db0231fe73cfb910c67b76da51a53a12d7e573f`; only the forest GLB golden pin was added, and all existing pins and other package bytes remain unchanged. No atlas, CPU blend, appearance-value change, dependency or lockfile change. Browser/GPU captures and actual native runtime proof were not run; headed visual acceptance remains open for the coordinator. All commits remain local. + +2026-10-12 package half of the layered-surface box, already proven by existing cook specs and left unticked on purpose. `packages/assets/__tests__/terrain-world.spec.ts` has `preserves every relative layer texture byte-for-byte and marks terrain nodes` (authored layers and the node and mesh `tnTerrainSurface` pointers) and `names a missing non-base texture before writing a package`; both pass, and the assets suite passes 590 with two worker-pool cases that pass 6 of 6 when rerun alone. `texturesDir` is an explicit option resolved with `path.resolve`, so a relative value means relative to the caller's working directory, which is the intended headless behavior. What keeps the box open is the other half of its proof: the cooked GLB still draws only the first layer, and the headed before and after visual judge has not run. + +2026-10-13 native packaging reproduction (engine layer, `packages/assets/src/compile.ts`): the retained accepted grid8 forest kit fails ordinary `build:desktop` against the freshly built V8 host. Preflight rejects `terrain/forest/world.4e55303c.glb` with 34 interleaved vertex views. The ordinary model pass already selects separate buffers for native targets, but cooked-world recognition deliberately bypasses all model passes and hashes only `terrain-world-v1`, so web and native reuse the same representation. Bounded repair: keep web byte-identical; use the existing model writer solely for native vertex layout, disabling optimization, texture conversion and LOD generation; distinguish native cache identity and report the pass that actually ran. Regression must prove a web-to-native build does not reuse the web file, geometry/material/image data survive, and repeat native compilation caches correctly. Then reinstall the changed package into the retained clean kit and rerun desktop packaging/playtest. No preflight bypass, performance claim or acceptance tick. + +2026-10-13 native layout repair verified: the existing model writer now emits separate vertex buffers for cooked worlds on desktop/Android/iOS, preserves authored materials (including duplicates), geometry and image bytes, and uses a distinct native cache identity. Web output remains byte-identical. Focused assets tests pass 115/115; assets typecheck and build/publint pass. Reinstalling the packed assets package into the retained grid8 forest game makes ordinary `build:desktop` pass against V8 host SHA256 `de2d9cf932ed8422b3241756d8361562bf63a53070502aafc3eecebfb83e4242`, without a preflight bypass. A desktop diagnostic scenario retains all behavior/resource/performance assertions and omits only unsupported native visual-metric evaluation: it reaches runtime-ready on NVIDIA RTX 2080/Vulkan, exercises the driven collision path and all four camera views, and produces nonblank 1280x720 captures (ground manually inspected). The scenario remains FAILED: render p95 242.09 ms exceeds 40 ms, and lake GPU/frame measurement presence rows fail. It used fixed-step timing and another lane has an active native renderer, so this is not an isolated steady-state performance result. Browser visual assertions, native visual judging and performance acceptance remain open. diff --git a/docs/PRDs/strata-terrain-hardening/PRD-584-an-agent-asks-for-a-forest-over-mcp-and-gets-a-60-fps-glb.md b/docs/PRDs/strata-terrain-hardening/PRD-584-an-agent-asks-for-a-forest-over-mcp-and-gets-a-60-fps-glb.md new file mode 100644 index 0000000000..27575f43da --- /dev/null +++ b/docs/PRDs/strata-terrain-hardening/PRD-584-an-agent-asks-for-a-forest-over-mcp-and-gets-a-60-fps-glb.md @@ -0,0 +1,187 @@ +# PRD-584 — An agent asks for a forest over MCP and gets a 60 fps GLB + +**Status:** PARTIAL +**Priority:** P1 — The epic's headline outcome: no MCP tool generates terrain today, and no measured number shows a handed-over Strata world holding 60 fps (AC-1 to AC-5). +**Complexity:** 7 (HIGH); risk override: closed-list boundary — a request-to-world tool sits next to the closed "preset/genre system" item +**Owner:** ThreeNative maintainers +**Depends on:** [PRD-583](PRD-583-a-strata-world-bakes-headlessly-into-an-instanced-glb.md) +**Epic:** [Strata terrain hardening](README.md) + +## Context + +Owner, 2026-10-10: "the AI agent could call some MCP endpoint like terrain_generation => +'Generate a forest for me' => and then instantly it's generated and a .glb is provided, and the +game can use it at min 60fps performance." + +Today, on `2d2124792`: + +- No MCP server exposes terrain. `packages/core/mcp/servers.mjs` wires `threenative-assets`, + `-sculpt`, `-engine` and `-blender`.

Decisions: D1 the server is hand-written stdio JSON-RPC, because the existing engine and blender servers are hand-written JSON-RPC with no SDK and their loops are bundled, not importable. D2 the server is a tsup entry of `packages/terrain` (`dist/mcp/server.js`, package `bin`), not a bundle in core, because bundling terrain into core closes the cycle core -> assets -> terrain -> core. Core gets only the shim `packages/core/mcp/terrain.mjs`, the `threenative-terrain` row in `MCP_SERVERS` and a `MCP_PACKAGES.terrain` pin; core gains no dependency on terrain. D3 terrain does not depend on `@threenative/assets`: the cook child loads it from the game project at run time and fails closed with `npm i -D @threenative/assets` when absent. D4 `packages/terrain/dist` stays under 2 MB. + Changed: all five kits are accepted and each cooked through the built server (forest 5.6 s wall, 18,515,644 B `world.glb`; coastal, alpine, desert and tundra about 1.2 s each). `bounds` is narrowed by `parseBounds` with no cast. A pre-aborted signal never spawns. A timeout or cancel kills the whole process group and removes the partial output. `out` is rejected when it or any ancestor is a symlink leaving the project (realpath containment, dangling links included). `pnpm sync:mcp` rewrote the template MCP configs for the fifth server. `AGENT-INTERFACE.md` names it. + Checks: `terrain-mcp.spec.ts` 23 of 23 pass. Red against the previous `child.ts` and `tools.ts`: 6 of the new cases fail. `mcp-install.spec.ts` 33 of 33 pass. Core typecheck 0 errors. Terrain `tsc --noEmit` has 165 errors in `starter/`, other specs and `examples/strata-terrain-preview`, 0 in `src/mcp` or `terrain-mcp.spec.ts`. Terrain build exits 0, `du -sb packages/terrain/dist` = 860,387. Stdio smoke through `node packages/core/mcp/terrain.mjs` lists `terrain_generate` and `terrain_patch` (`SMOKE PASS`). Scoped Biome exits 0 with one existing complexity warning in `servers.mjs`. Doctor pin test, primary-docs and release candidate cases pass with `-t "MCP|bundled"`. + Open: `@threenative/terrain` is unpublished (npm 404), so the shim's npx fallback fails in a project that does not install it. `scripts/verify-golden-path.ts` (`MCP_SURFACES`, needs a recorded `terrain-mcp-tools.json`) and `scripts/verify-registry-install.ts` (safe tool, spec fixtures) still list four servers, so their specs fail until updated. The full runs of `doctor.spec.ts` and `verify-registry-install.spec.ts` have other failures not triaged. Species are the tracked starter GLBs, not the asset MCP download path. The result has no `ctx.load` snippet, triangle count or draw count. The cook reads data files from `starter//`, which AGENTS.md says package code never imports.

Changed: `MCP_SURFACES` and `MCP_SAFE_TOOLS` carry `threenative-terrain` (probe: `terrain_patch` with an empty command list, never a cook); `terrain-mcp-tools.json` is written by `scripts/capture-terrain-mcp-tools.ts` and compared to the served tool table in `mcp-tool-schemas.spec.ts`. Doctor treats the terrain server as an optional addon: it is not probed through the shim's npx fallback when `@threenative/terrain` is absent, and says `Run: npm i -D @threenative/terrain`. `terrain_generate` now returns the kit as `recipe`, the `world.glb`, `recipe.json` and `world.json` paths, `triangles`, `instances` and `draws` read from the default scene of the produced GLB, and a three-line `ctx.assets.model` snippet (`ctx.load` is not an API in this repo). `triangles` counts every instance in full before LOD and culling, `draws` counts primitives with an instanced primitive once.

Downloading the `.blend` alone is insufficient: the existing exporter first stopped on its missing bark image. The provider lists 18 PNG dependencies; retrieving them through the same MCP, verifying their declared sizes/MD5 and restoring their declared relative `textures/` paths took 1.265 seconds, all uncached. The unchanged existing `prep-polyhaven-fir.py --only b:2` then exported and self-checked the authored LOD2 in 3.848 seconds: 54,927 triangles, one mesh, four materials, six embedded images, POSITION/NORMAL/TEXCOORD_0 and base Y zero. Its 5,153,060-byte GLB has SHA-256 `a7e1f126ba7c09aa160f82e200689312334204928c9d822a1eaf13ed9d259dc8`, exactly matching the existing repository asset. The successful component timings sum to 6.900 seconds; this was a diagnostic sequence, not a single end-to-end cold forest generation. The existing 10 GiB downloader cap was unchanged.

A bounded Haiku MAX arm timed out after saving only additions to existing `model-lod-loader.spec.ts`; no production fix landed. The actual createAssetLoader/GLTFLoader fixture carrying EXT_mesh_gpu_instancing and TN_discrete_lod produces 7 passing and 2 failing tests (10.45 s): near/far instances draw the same geometry, and a separate ownership assertion finds no chain on the inspected base geometry (0 levels versus 2 expected). This does not isolate the partition-hook cause from chain association, so no GREEN or complete behavioural proof is claimed. Scoped test Biome passes; core typecheck fails on missing local playtest protocol/three declarations. No assets cook, native/browser conformance proof or FPS measurement ran; the current cook also still needs existing chain generation and writer preservation before its terrain triangle budget can improve. No acceptance box ticked. + +2026-10-11 imported-LOD runtime component verified locally, without an acceptance tick: retained RED loader tests were committed unchanged as `03161de4b`. The empty chain was an association loss, not missing fixture metadata or a geometry clone: the fixture writes TN_discrete_lod on its primitive (`packages/core/__tests__/model-lod-loader.spec.ts:136`); Three's GLTFLoader constructs the imported InstancedMesh over the original geometry without transferring its primitive association (`packages/core/node_modules/three/examples/jsm/loaders/GLTFLoader.js:1762`), stamps only its node association (`:4402–4411`), and drops the replaced source mesh's association (`:4506`). The reader consequently skipped it for missing mesh/primitive indices. DiscreteLodPlugin now recovers those indices from the glTF node and primitive order, including multi-part nodes, and the asset loader injects the existing attachInstancedLod mechanism after decoded-chain registration, avoiding a runtime import cycle. Imported instances use the existing 4 px projected-error default and hysteresis, with manifest runtime overrides; an unchained primitive remains unchanged. The retained ray fixture required front-facing triangle winding and a ray away from a shared edge. Local focused baseline: 69 passing / 2 failing specs in six files (loader 7 / 2); final: 72 passing / 0 failing (loader 10 passing, including added mixed-chain multi-part coverage). Tests verify independent near/far detail, stable authored slots/count, public ray-hit ids, manifest budget/hysteresis, and disposal that releases partitions/restores base without disposing shared chain geometry. Core typecheck passes after the permitted @threenative/playtest build restored local protocol/three declarations; scoped Biome passes with eight cognitive-complexity warnings and no errors. No packages/assets changes, browser/native playtest, real-world triangle count or FPS measurement ran. The cooker still must emit and preserve valid TN_discrete_lod chains for real Strata worlds; 60 fps acceptance remains open. + +2026-10-11 combined-world cooker LOD component verified locally, without an acceptance tick: `cookTerrainWorld` reuses `generateDiscreteLod` on near species with cutout conversion disabled and vertex-copy card reduction disabled; the final writer registers `TNDiscreteLod`. Index-only chain errors and error scales follow the existing source-node transform during flattening. The real forest spec runs the actual cooker on the shipped recipe, RAW16 sidecar, models and ground textures (5.638 s in the final focused rerun), checks decoded/transformed source vertex hashes, unchanged LOD0 indices/material factors, shared vertex buffers, transformed error scales, and computes selection from the cooked GLB's instance attributes using core's projected-error selector, 4 px budget and 0.15 hysteresis starting at LOD0. Camera position (256,40,600), look-at (256,10,256), 60-degree vertical FOV, 1920×1080 viewport, near 0.1, far 2000; this counts all placements without frustum/shadow-pass culling and is not a GPU frame measurement. Clean HEAD before: base and submitted 505,387,464 triangles, no species chains. After: unchanged base 505,387,464; submitted 18,917,904, including unchanged terrain 139,264. Fir: 3,100 instances, base 398,238,400, submitted 13,001,400; primitive triangle ladders including LOD0 [9582,2460,1339], [78776,3466,1488,722], [35136,1757], [4970,2418,902,376]. Boulder: 320 instances, base 10,579,200, submitted 528,640; ladder [33060,18794,6432,2350,1652].

Before/after kit bakes contain 22 files: only world.glb changes, SHA-256 e64b584dba6fdfd0ab05c30e2d0b0b3ad39231ae735208ef5283a8c2b6df3993 → c23570826bc1100f13768ae57c7922b50e321327ec810ccb426e4b7fea818700, because of added index chains and transformed error metadata; all 21 other files, including streamed models and every non-GLB output, retain their hashes. A byte comparison also confirms 109 default-scene vertex/index/instance streams and materials, textures, samplers and embedded images unchanged. No existing pin changed: the starter-kit pinned hashes cover non-GLB outputs, and the assets terrain-world spec has no cooked-GLB hash pin. Rebuilding checkout prerequisites and assets restored the clean baseline: requested four-file specs 92/92 passing, including non-finite placement; after 93/93 passing, followed by 20/20 terrain-world specs on the final census edit. The retained transformed-error assertion fails without source-scale propagation (1.3152257204 versus 9.2575621605) and passes with it. Assets/core typechecks and assets build pass; scoped Biome passes with seven warnings and no errors. No browser, GPU, native or FPS run; coordinator qualification and all full acceptance criteria remain open. + +2026-10-11 Phase 3 scaffolding added, web smoke did not reach a frame (no box ticked). `pnpm verify:forest-playtest [--target web|desktop]` (`scripts/verify-forest-playtest.ts`, spec `scripts/__tests__/verify-forest-playtest.spec.ts`, 3/3 passing) packs the workspace, scaffolds the stock starter, calls the real `terrain_generate` through the core shim over stdio with `{ kit: "forest" }` (the tool takes `kit`, not `request`), inserts only the printed `ctx.assets.model("worlds/forest/world.glb")` + `ctx.scene.add(world.scene)` lines at the start of `Play.load`, and runs `template-playtests/starter-forest/forest.playtest.json` (web) or `forest.native.playtest.json` (desktop): 300-tick ArrowUp walk, `assert.performance.maxFrameMsP95 16.7`, `movement` -z >= 0.5. Web smoke on the NVIDIA GPU (`--browser-recipe webgpu`, private Xvfb) exited 2 with `TN_PLAYTEST_BRIDGE_MISSING` at 0 frames: no adapter, p50 or p95 was measured. Cause, shown with a control: the same scaffold without the two load lines boots (bridge present, 300-frame windows of p95 5.3 to 6.5 ms). With them, the page never requests `world.glb` and stalls with `TN_STARTUP_STALLED`, because the production build resolves assets through `assets.manifest.json` and `worlds/forest/world.glb` under `public/` is not listed (`packaging: 28 unmanaged file(s)`; `resolveCandidates` throws "is not listed in the asset manifest", which surfaces only as the stall). Moving the world to `assets/worlds/forest/` so the pipeline lists it made `pnpm build:web` run past 10 minutes (KTX2 encoding of the world's textures) before it was stopped, so that route is not yet measured. Open: the tool's default `out` and printed snippet do not load in a manifest-built game. + +2026-10-11 D1–D5 production hardening (no boxes ticked). `terrain_generate` now derives the configured `assets.source` through the installed Vite config loader, defaults to `assets/worlds//`, rejects outputs outside that source root, and prints a source-relative manifest key. A new cooker marker, `asset.extras.tnTerrainWorld = 1`, selects validated GLB passthrough: copy/hash/list without model passes or name-insensitive deduplication; ordinary models still process. Initial Scene.load failures and rejected `#goto` transitions now report the original error through `onLaunchFailure` and `TN_STARTUP_FAILED`; the previous `transition.then(settled, settled)` handler handled the rejection without reporting it. Request matching is deterministic in starter order: forest/pine/woods, coastal/beach/coast/sea, alpine/mountain/snowy/peaks, desert/dunes/sand, tundra/arctic/ice; `kit` overrides matching, unmatched requests list all five kits, and the recorded MCP schema is regenerated. Both terrain specs now use `makeTempDir`, without guard allowlisting. Checks: 212 focused tests pass across asset compile/terrain-world/shared-images (88), core game/launch diagnostics (62), terrain MCP (36), terrain consumer (18), temp-dir guard (1), and MCP schemas (7). Assets/core typechecks and assets/terrain builds pass; scoped Biome passes with warnings. Terrain typecheck still fails in untouched preview code because `examples/strata-terrain-preview/src/world/horizon.json` is missing. The single requested NVIDIA web run built within the 10-minute limit and loaded/walked: adapter.info vendor `nvidia`, architecture `turing`; startup ready; movement 1.40 m along -z; zero console/network errors. Nearest-rank frame times over 199 samples: p50 21.4 ms, p95 213.6 ms. Overall FAIL: unchanged p95 ceiling 16.7 ms.

The failure is in association discovery: Three.js replaces `parser.associations` with each scene's reduced map, so alternate species LOD scenes remove the main world's instanced-node mappings before `DiscreteLodPlugin.afterRoot`. The shared plugin now loads node dependencies and retains their complete association map in `beforeRoot`, then uses it for primitive/instancing discovery. No distance, threshold or appearance value changed. RED: the real cooked forest loaded through `createAssetLoader.model("worlds/forest/world.glb")` had zero partition children; a minimal multi-scene loader regression also returned zero instead of two. GREEN: 61/61 tests across terrain-world, model-lod-loader/runtime/clone/join pass; core and assets typechecks pass; scoped Biome passes with warnings. `pnpm capabilities:sync` and `pnpm api:surface:sync` pass with no tracked drift. Full lint passes on the Debian offload lane with warnings; full typecheck fails on absent package build outputs, and full `pnpm test` stops because that lane has no Git HEAD, so full qualification remains unverified. The single requested NVIDIA-environment web command (`flock /tmp/strata-terrain-gpu-proof.lock pnpm verify:forest-playtest`) exited 1 before browser launch: the driver inserts the tool's static `applyTerrainSurface` import inside `Play.load`, and the production scaffold build rejects `src/scenes/Play.ts:61` with a top-level-import parse error. Adapter, p50, p95 and triangles/frame were not measured. No second forest run, tuning, native run or push. Command output: `/tmp/584lod-forest-web.log`. + +2026-10-11 bounded item 3 skipped after two recall runs returned `none` (1/1 focused failure, then 17/18 pass). The `procedural-vegetation` not-owned situation `generate a forest of trees` preempts the request. Adding an honest forest-world situation to `cookTerrainWorld` also makes `pnpm capabilities:sync` reject overlapping ownership (score 0.375000). Trial edits reverted; AC-3 and phase 2 remain open. Resolving the ownership declaration is required before description-only ranking can work; no ranker special case added. + +2026-10-11 Black-fir diagnosis, root cause not found, no boxes ticked. In a scaffolded starter with the cooked forest `world.glb`, every fir renders near-black under the starter's post chain, and the same trees render lit with `exp=nopost`. This is not a regression between `3b32a45c2` (the SHA nearest the PR comment frame) and `b202ca25a`: `git diff 3b32a45c2 b202ca25a -- packages/create-threenative/templates/starter/src` is empty, and the HEAD template and cooked GLB on core built at `3b32a45c2` (with that SHA's Three patch) also render black. The PR comment frame (`BAD-prd591-hardware-walk`) came from the `examples/strata-terrain-preview` app, not a scaffold, so it never proved the starter path. Measured on the NVIDIA adapter (`vendor: nvidia`): a plain red `MeshBasicMaterial` on every fir is red with no chain and black under the default chain, so the cause does not depend on material, lighting, shadows, fog, `alphaAntialiasing` (turning it off changes nothing) or albedo. With the canvas CSS background set to magenta, fir pixels read about (87, 1, 86): near-zero RGB with alpha about 0.66, so the chain output carries a wrong alpha and colour on fir pixels while terrain stays opaque. Removing bloom, vignette, GTAO, grade and grain together turned the red firs red again; removing only some of them did not. The stage that zeroes fir RGB is therefore unidentified. Next step: add a per-stage alpha and RGB readout on a fir pixel to `WorldEnvironment`, then bisect stages one at a time. The playtest has no luminance assertion, so the black frame passed the 584 walk. + +2026-10-11 Black-fir root cause found and fixed in the cooker (layer: engine, `packages/assets`), no boxes ticked. The cooked `world.glb` stored all-zero vertex normals for every instanced prop (fir 5 774 of 5 774, boulder 19 773 of 19 773, fir-c 5 750 of 5 750 vertices), while the source `fir.glb` had none. `@gltf-transform/functions` `transformMesh` writes a normalized-integer NORMAL back through `decodeNormalizedInt` instead of the encode function, and `addInstancedSpeciesNode` (`packages/assets/src/world/terrain-world.ts`) flattens each quantized species through it. Zero normals mean no direct light, and the starter's GTAO read zero MRT normals (confirmed with a normal-target view: tree pixels were 0, terrain and a plain user box were not) so its raw occlusion was 0 on trees. The earlier alpha 0.66 was premultiplied-canvas compositing of that near-black, not a stage bug. Fix: `dequantizeNormals` converts a normalized NORMAL to float before `transformMesh`. RED: new spec "keeps the unit length of quantized species normals through the flatten" fails with length 0, passes after; the real-forest spec's expectation had encoded the same bug and now transforms floats. Tree-only metric (pixels that change when firs are hidden, same pose, NVIDIA turing adapter): mean sRGB (13.8, 25.2, 29.8) before, (16.5, 20.7, 14.6) after, p90 luma 0.095 to 0.181, two identical runs per arm. A fresh read-only `claude -p --model sonnet` judge returned IMPROVEMENT on all three pairs (run1, run2, pose2); its ranked remaining defects start with foliage still near-black (GTAO radius 0.35 m and scale 1 crush dense cutout canopies: GTAO off or scale 0.3 lifts tree luma from 0.076 to about 0.2, an unjudged look change left for the template owner), then no visible sun shading, flat sky and fog, and an empty ground. The `forest world.glb` golden hash in `packages/terrain/__tests__/starter-kit.spec.ts` was repinned for the corrected bytes. The standard forest walk playtest frame (spawn arena) shows no trees, so a tree-pixel assertion there is not possible without a camera pose step; the data-level spec is the guard. Open: the visual-judge box for AC "looks lit" stays unticked because the verdict is IMPROVEMENT-from-black, not AAA. + +2026-10-12 forest kit sky (game layer, `packages/terrain/starter/forest/sky.ts`): the overview and lake poses showed a flat white sky (80.5% and 63.5% of the top 30% of the frame at all channels >= 245) with a hard horizon. The kit sky now compresses only the lower and near-horizon dome (radiance scaled 0.3 to 1.0 by elevation) and blends it into the haze colour, leaving the upper blue sky and haze density alone. After: 0% of those pixels clipped in both poses, top-30% median RGB 248,248,248 to 218,226,230 (overview) and 222,229,232 (lake); ground and edge unchanged (190,220,238 to 188,219,236). Kit run on verified NVIDIA Turing (private Xvfb), both runs pass all kit assertions. A first attempt (global radiance x0.06) was judged REGRESSION (dusk-navy ground and edge poses, grey overview) and discarded. Visual judge, fresh read-only Sonnet subagent, two runs per pose: overview IMPROVEMENT, lake IMPROVEMENT, ground NEUTRAL, edge NEUTRAL, OVERALL IMPROVEMENT, runs agree. Judge's remaining complaints, not fixed: the overview and lake sky is a dull grey-lavender and does not match the saturated blue of the ground pose, and the lake shows no sky reflection. Images: `pr483/kit-sky-{overview,lake,ground,edge}-BEFORE-AFTER.jpg` on `strata-hardening-screenshots`. Native rendering unverified. + +2026-10-12 forest kit lake (game layer, `packages/terrain/starter/forest/water.ts`): the lake was a flat dark navy slab with a hard sandy rim (lake-pose median RGB 17,47,50, no reflection, no depth). The material now uses a desaturated teal body, bed-depth shading, a widened shore fade with no foam rim, a capped grazing-angle highlight and a stronger sky-tint weight. After, on verified NVIDIA Turing (private Xvfb): lake median 17,47,50 to 32,94,99, overview 51,77,85 to 64,110,118, ground-pose water max-channel median 114 (no blow-out); kit assertions pass 25 of 25. Two earlier attempts were judged REGRESSION (neon pool-blue with a near-white ground pose) and NEUTRAL (white shore rim and a cream grazing streak) and were discarded. Visual judge for the final attempt (fresh read-only Sonnet subagent, two runs per pose): lake IMPROVEMENT, overview IMPROVEMENT, ground IMPROVEMENT (water strip only), edge NEUTRAL, OVERALL IMPROVEMENT, runs agree. Not fixed, the judge's remaining complaints: the lake body is nearly uniform flat teal, with no visible sky reflection or sun glint, the teal is slightly too saturated against the olive forest in the overview, and the wide shore fade tints the ground olive. The measured near-shore minus far-water luminance gap fell (+8.05 to +2.55), so the depth-gradient goal is not met.

The run is NOT valid proof for the bound: `phases.hostGap` is 57.8 ms of a 100.9 ms frame and `TN_SCENE_WARNING` reports `gpuShare` 0.009 to 0.061, which is the Xvfb present throttle ([desktop-xvfb-presents-throttle-fps] pattern), so the bound needs a real display. The same run records 10.85 M main-pass triangles over 278 draws and `trianglesPerDraw` 39,764, so the triangle cost named in README item 4 is real and independent of the throttle. Next: run on a real display (needs the owner to confirm the desktop is idle), then read `TN_WORLD_IMPOSTOR asset=fir reason=` and `TN_LOD_BIAS` markers, which this report does not carry. + +2026-10-13 AC-4 web walk on a real display, Omarchy (no box ticked): `pnpm exec tsx scripts/verify-forest-playtest.ts --target web` at `fb775277f`, headed on the machine's Xwayland display, adapter `intel / gen-9` (Intel HD Graphics 620, 2 cores, Wi-Fi), 364 samples.

This is a 2017 ultrabook iGPU, so it does not speak for the bound on the RTX 2080: the NVIDIA run on `:0` is still owed (the Xvfb NVIDIA run, 149.5 ms, is invalid because of the present throttle).

The last 30 samples still have p50 50.3 ms and p95 67.6 ms. This is not the required 300 rendered-frame steady walk: fixed-step ticks do not establish that sample count, and first-use compilation remains in the series.

GPU busy 12.6%. Raw trace: `artifacts/pr483-forest-real-display-trace.json`; command exits 0, which validates trace collection only. The first-use stall remains inside this trace, so its aggregate rate is not a steady FPS result. Next diagnosis: separate that compile window and measure empty LOD partition processing before choosing a renderer change; no speculative optimization or budget change is applied. + +2026-10-13 measurement correction (verification harness): both browser and desktop calls in `scripts/verify-forest-playtest.ts` now pass the existing `--live-clock` flag. The earlier fixed-step walk rendered only 71 observed frames, so it cannot establish the intended live walk or steady-state FPS. With a live clock, tick-based browser steps wait real rAF frames instead of advancing the synthetic bridge clock; the native runner receives the matching wall-clock setting. Existing setup specs pass 3/3 and scoped Biome passes. No runtime rerun or FPS acceptance is claimed: another lane currently owns an active native GPU renderer. The scenario performance series still has no startup-discard or minimum-count option; steady-state acceptance must additionally use the existing perf-marker window assessor with enough completed windows. Its default two steady windows contain only 600 frames, not the required 1,000-frame/30-second minimum. All runtime/performance boxes stay open. + +Live-clock retry preparation: the real latest local-framework scaffold, `terrain_generate` forest bake and `build:web` complete successfully. The browser CLI then reports the shared capture lock held by another lane; only this goal's queued CLI was terminated after verifying its parent chain belongs to this checkout. No browser scenario executed. The fully built game is retained at `/tmp/threenative-forest-playtest-DnOVg6/forest`, so the next retry runs its existing CLI command directly instead of rebuilding or repacking. Runtime/FPS boxes remain open. + +2026-10-13 live-clock browser observation: the already built generated forest was copied unchanged to the now-free laptop GPU. Both copies contain 88 files with path-and-content tree SHA256 `3332d272ed7f490c11b3a3bd6c39883bd07e020cef4f1dc101ab5ff910147178`. The existing runner uses the frozen forest scenario, hardware Intel gen-12lp WebGPU, live clock and an ordinary HTTP server. It fails: frame p95 125.8 ms > 16.7 ms (305 observations) and required −Z movement is effectively zero. Diagnostics, network/console policies and runtime-ready pass. Input injection is clock-independent, but the controller/contact cause remains under investigation; odometer growth alone does not prove successful held-key locomotion. Retained browser distribution/scenario/artifacts: `/tmp/pr483-forest-live-dccd` on laptop; full CLI log: `/tmp/pr483-forest-live-intel.log` on desktop. + +The browser console does capture the existing `TN_FRAME_BUDGET` markers. Extracting its ten messages into the existing perf CLI file input disproves the earlier read-only claim that browser marker evidence cannot be consumed. The assessor, with six required windows, 60 FPS and 16.7 ms bounds, fails (minimum FPS 36.68/43.33, frame p95 113.7 ms). Every captured window still reports `surface.compiling: true`, so none qualifies as a settled measurement. No steady-state result or acceptance tick follows from these values. A future measurement must collect enough actual completed frames and elapsed time after settling; requested tick/rAF counts alone do not establish that window. + +2026-10-13 measurement acceptance repair (playtest harness layer): the existing perf assessor now excludes every window explicitly marked `surface.compiling: true`, retaining the raw budgets for attribution and listing the discarded window ids. It keeps the established first-window discard and legacy records without that optional observation; malformed provided surface records/compilation flags throw. The new regression reproduces a false pass from fast-but-compiling windows before the fix. Parent-reviewed focused tests pass 86/86; playtest build, declaration generation and publint pass. The rebuilt CLI against the actual browser marker file exits 2 with `TN_PERF_WINDOWS_MISSING`, zero settled windows and all ten ids discarded. This corrects measurement eligibility; it supplies no new FPS or runtime acceptance. + +2026-10-14 physical handoff repair, no acceptance box ticked: the MCP load snippet now reconstructs the baked RAW16 ground with the shipped Heightfield sampler and a fixed Rapier heightfield body, centered on the manifest extent. Removing its scene anchor disposes the body. The snippet also supplies the shipped GLTF type to the generic model loader; a generated consumer typecheck exposed the previous `unknown` result. Both asset-source regression cases fail against the old render-only snippet and pass with the collider, including column-major heights, manifest-relative lookup and scene-exit disposal. The final terrain MCP suite passes 39/39; the complete terrain suite passes 317/317 across 29 files, the forest verifier passes 3/3, and terrain typecheck, build and publint pass. The freshly packed consumer passes its own TypeScript check and web build. Its build initially rejected three generated world copies at the unchanged 64 MB asset budget; the two unused copies were moved outside the AFTER asset tree, preserving both them and the original baseline. The actual live-clock forest scenario then failed on the Intel adapter: 540 requested ticks, 300 performance observations, p95 136.6 ms against 16.7 ms, and net -z movement -0.000000835 m against the required 0.5 m. Startup compilation completed at 31,654.5 ms and framework readiness at 31,850.2 ms; console, network and runtime diagnostic checks passed. The collider component alone does not repair the live walk. Ground-support/spawn and collider lifetime are under investigation; native behaviour, visual acceptance and steady 60 fps remain open. No acceptance box is ticked. + +2026-10-14 spawn diagnosis, no acceptance box ticked: the installed core heightmap loader and sampler read the actual generated world surface at the stock spawn x=-2, z=0 as 11.400151388230618 m. The stock capsule center is 0.9 m and its feet are at 0 m, so it begins beneath that heightfield. The existing Player constructor already accepts an explicit spawn position; the forest proof transformation is being adjusted to retain the tool-emitted heightfield from load until enter and derive the initial height at the actual spawn coordinates. This changes the generated proof game, not the stock template, and introduces no constant terrain elevation. Runtime movement and frame-time acceptance remain open until the unchanged scenario passes. + +2026-10-14 owner visual rejection after the measured spawn change: the RTX 2080 live-clock walk moves 14.233197509785896 m along -z and passes console/network/runtime diagnostics, but p95 is 32.9 ms against 16.7 ms. Movement alone is insufficient: the owner observed the character sinking into the surface, facing backward while moving north, coarse ground texturing and poor tree appearance, and supplied the BEFORE screenshot. These remain failures. Opus 5.5 at high effort was explicitly requested for the visual diagnosis and is reviewing that image and the actual game/terrain sources. No visual or performance acceptance is claimed. + +The spawn transformation has a reproduced RED against the prior flat-floor setup and six passing verifier tests after the change. A separate readiness-guard regression was reproduced before adding the field to the existing startup guard. The independently rerun six tests, scoped Biome, generated consumer typecheck and web build pass under Node 20. Two labelled RTX/Turing diagnostic captures are retained; their live-clock end positions differ by 0.167 m, so they are not claimed as the exact-pose visual acceptance pair. The owner-supplied image remains the visual rejection reference. + +2026-10-14 owner-image diagnosis and first grounding attempt, no box ticked: the explicitly requested Opus 5.5 high audit completed against the owner image and actual generated game. It confirmed hidden feet and rejected the assumption that ground filtering was simply off: mipmaps and anisotropy were already enabled. Physics samples the clearing at 11.400 m; the capsule center at 12.310 m is correct. The stock template's arena-only support callback disables visual grounding outside the arena. Removing that redundant callback and deriving support from the grounded body passes 114 focused tests; after removing implementation-mirroring assertions, the independently rerun scaffold and forest-verifier suites pass 44/44. The generated consumer typecheck and build pass. However, the actual updated Intel/gen-12lp live walk still FAILS: -z movement 15.766 m passes, diagnostics pass, but visualAttached changes true to false, clearance becomes -0.258862 m and correction becomes disabled while grounded remains true. Its p95 is 69.7 ms against the unchanged 16.7 ms limit, with 323 observations; this is not settled performance proof. The remaining vertical-velocity gate and animation heading are under investigation. The scenario now asserts attachment, ±0.1 m clearance, grounded contact and enabled correction on both browser/native paths; native is unrun. Opus has a separate bounded tree-source repair task. Grounding, facing, art, visual judging and 60 fps acceptance remain open. + +2026-10-14 facing regression reproduced and repaired, no acceptance box ticked: an actual generated-consumer live walk on Intel/gen-12lp moves 15.866 m north while the old Euler interpolation changes facingZ from -1 to +1 (the character faces south); the new facing assertion fails. The temporary actual-mannequin/SkeletalMesh3D probe also shows matrix decomposition changes Euler representation around π, so interpolating only rotation.y turns the figure back toward identity. The template now interpolates the heading quaternion with the same turn rate and uses its existing debug surface to expose facingZ; the browser/native forest scenarios require facingZ ≤ -0.95. After the source change, the actual live walk moves 15.766 m north with facingZ -1 before/after, attached feet, measured clearance 0, grounded contact and correction enabled; movement and diagnostics pass. A continuous consumer-only diagnostic records no grounded positive velocity rejected by the gate during this run, so the previous intermittent correction failure is not established as a vertical-velocity problem. The p95 still FAILS: 81.7 ms against 16.7 ms, 308 observations, startup/compilation mixed into the walk. The final focused scaffold/verifier matrix passes 51/51 in three files; scoped Biome and generated-consumer TypeScript/build pass. Exact-pose visual judging, repeated grounding stability, jump regression, native execution, tree/ground art and settled 60 fps remain open. + +2026-10-14 publication preflight: the pre-push drift check correctly rejected the starter scaffold's prior tree hash after the intentional Player/Play changes; the other twelve template hashes matched. Updating only that starter snapshot to the measured generated-tree hash passes the complete 68-test scaffold suite. No quality or runtime threshold changed. + +2026-10-14 extended hardware baseline, no box ticked: a long live-clock Nvidia/Turing 1920×1080 forest walk reaches 174.95 m north and passes attachment, ±0.1 m clearance, ground contact, correction, facing and diagnostics at its final sample. The full run still fails p95 at 44.8 ms against 16.7 ms. Signal observations locate walking after tick 8284; excluding the boundary window leaves nine consecutive non-compiling walking windows, 2700 main-pass records, and at least 84.1455 seconds of accumulated measured cadence after rounding allowance. Those windows fail both budget/cadence: callback p95 28.5–50.9 ms, presented p95 29.1–54.5 ms and 25.85–38.30 FPS. Startup is ready with compile settled and every selected window retains scale 1/MSAA 4. The empty-page control runs at 59.34 FPS on the 59.96 Hz display with no tracer blockers. OS foreground was explicitly activated during the run but is not joined continuously to every window, so full foreground-qualified performance proof remains open. The owner identifies the close/far tree-shape transition as a defect and rejects overall light/shadow/atmosphere; the baseline is being used to repair LOD and authored appearance, not to tick acceptance. + +2026-10-14 develop integration audit, no box ticked: merged remote develop 99aeb6e30 at 6db7012e4, combining the branch async lightmap bake with PRD-568 ASTC encoding. Focused asset/core tests pass 198 with one skipped; assets/core typechecks and scoped Biome pass. The retained forest still pins older core/assets archives and must be rebuilt from a fresh complete cohort. Existing generated source already adopts GPU tier selection and height fog/grading, but its ordinary directional shadow map excludes VirtualShadowNode and its whole-world GLB load does not use WorldCells/TerrainTiles. Therefore cached shadow pages and streamed GPU terrain morph/selection are not established benefits of this consumer merely because their PRs are in branch ancestry. The existing streaming and virtual-shadow paths are being evaluated before new performance claims; ASTC applies to Android/iOS, not this desktop baseline. + +2026-10-14 integration candidate, no acceptance box ticked: the cooked tree distortion is reproduced as index-only LOD levels retaining pre-compaction vertex numbering. The shared asset-cook fix remaps every level and mirrored winding, isolates shared chain/accessor state, and rejects malformed indices through the existing validator plus base bounds checking. Original-transform and shared-accessor RED reproductions fail; final terrain-world suite passes 29/29, including the real forest. The canonical MCP handoff now streams the existing world.json with WorldCells and loadTerrainSplat, preserves the complete collider/measured spawn, derives reach and placement budgets from the manifest, and releases resources on exit and load failure. Verifier/MCP tests pass 47/47. Opus 5.5 high supplies an optional cached-shadow path in generated render source while preserving the ordinary arena map; the forest verifier derives outer windows from the measured world diagonal and forwards regional stream invalidations. Assets/core builds and relevant typechecks pass. Rebuilding assets resolves the previously stale ASTC failures: focused mobile/ASTC contracts pass 14/14. Strict fresh consumer, hardware visual judgment, continuous grounding, settled performance and native proof remain open; the mechanism candidate does not establish the owner AAA scene bar. + +2026-10-14 terrain sampler-input normalization, bounded CPU candidate ready for runtime, no box ticked: `cookTerrainWorld` now gives each map kind (diff, nrm, orm, h) one size and one input encoding across all layers. A kind whose maps already share size, format and alpha keeps its authored bytes. Otherwise every map in the kind, the largest included, becomes lossless PNG at the largest width and height: decoded pixels kept, smaller maps resampled up, never down. This normalizes inputs only; the asset compiler still picks each texture's codec from its content. Both cook callers (`packages/terrain/src/mcp/cook.ts`, `packages/terrain/src/kit.ts`) route through this function and did not change; the MCP path loads the built `@threenative/assets`, which this lane did not rebuild. Real forest sources: grass, dirt and moss diff/nrm are 1024×1024 JPEG, rock is 512×512 JPEG. The published 0.1.0 archive and `starter-assets.json` are untouched. The regression cooks four layers with a half-size rock across all four kinds: every cooked map is PNG, decodes through `decodeImageBytes` to 64×64 RGBA8, the larger maps' decoded RGBA equals their source decode, and core `stackLayers` returns a 4-deep array per kind through a copying renderer stub. The size assertion fails with the normalization disabled (32×32 versus 64×64). Focused specs pass: assets terrain-world 30/30 and terrain-editor-cook 2/2. CPU compile probe on the eight real forest maps (current source `compileAssets`, web, budget none, installed Basis transcoder): all eight compile to KTX2 at 1024×1024 with 11 mips. The normal kind is compatible: four UASTC maps with one signature, which saves 3 samplers. The diffuse kind is still mixed: grass, dirt and moss are UASTC and the resampled rock is ETC1S, so it does not stack. Compiled bytes: diff 4,241,244 (PNG inputs 10,247,896), nrm 5,360,040 (PNG inputs 10,364,486), total 9,601,284. Expected effect, not measured: 19 samplers drop to 16, at the portable limit of 16; the owner accepts 16 as the nearest correctness target. Not every acceptance criterion is complete. The mandatory next step for root: actual NVIDIA and Intel runtime runs with zero WebGPU validation errors. No GPU, browser, native, visual or 60 fps run happened in this lane; those boxes stay open. diff --git a/docs/PRDs/strata-terrain-hardening/PRD-585-strata-proof-runs-in-ci.md b/docs/PRDs/strata-terrain-hardening/PRD-585-strata-proof-runs-in-ci.md new file mode 100644 index 0000000000..6d5189c0df --- /dev/null +++ b/docs/PRDs/strata-terrain-hardening/PRD-585-strata-proof-runs-in-ci.md @@ -0,0 +1,111 @@ +# PRD-585 — Strata's proof runs in CI, not only by hand + +**Status:** PARTIAL +**Priority:** P1 — No Strata playtest, consumer check or editor script runs in CI, so every later PRD in this epic can regress unseen (AC-1 to AC-5). +**Complexity:** 4 (MEDIUM); risk override: none +**Owner:** ThreeNative maintainers +**Depends on:** None +**Epic:** [Strata terrain hardening](README.md) + +## Context + +Audit of `2d2124792` (2026-10-10): + +- `.github/workflows/ci.yml:125-126` and `:275-277` run only `pnpm --filter strata-terrain-preview bake`. + No `test:terrain:*`, `test:kit`, `test:consumer` or `verify-*.mjs` runs in any workflow. +- `examples/strata-terrain-preview/package.json:12-20` wires 7 `verify-*.mjs` scripts; 10 more + are chained from them, undocumented. `playtests/walk.playtest.json`, `scripts/measure-*.mjs`, + `check-water.mjs`, `check-temperate.mts` and `consumer-world.mjs` are referenced by nothing. +- `packages/terrain/__tests__/forest-runtime.spec.ts:11` mocks `WorldCells.load`.

Failures: `afterFirstFrameTaskMs` 490 > 250 ms, `timeToReadyMs` 21,395.6 > 15,000 ms, `maxViewGpuMs` 326.69 > 12 ms, and a `MeshBasicNodeMaterial` pipeline multisampled-binding mismatch (group 1, binding 2). Thresholds remain unchanged. The independent follow-up passed `test:terrain:editor` on the same Intel WebGPU candidate, including transform, conflict/reload/undo, tool and environment checks. `test:consumer` failed during scaffold install: the old Corepack launcher targeted nonexistent pnpm 12 `bin/pnpm.cjs`. The cached package exposes a native `pnpm` launcher, verified at version 12.10.1; a retry uses that launcher on a job-local PATH, without changing system defaults. That retry reached dependency installation, then failed closed with `ERR_PNPM_IGNORED_BUILDS` for core, runtime-native, esbuild and sharp; the generated project build-approval policy needs repair before consumer behavior can be verified. No approval policy was bypassed. This is failed local evidence, not CI acceptance. + +A desktop comparison on the same executable candidate used verified NVIDIA Turing WebGPU and passed 59/62 assertions. Its failures were `afterFirstFrameTaskMs` 12,635 > 250 ms, `timeToReadyMs` 38,741.8 > 15,000 ms, and `maxViewGpuMs` 35.22 > 12 ms. The Intel shader error did not recur. This is another failed local performance result, not runtime or CI acceptance. Generated consumers currently omit `packageManager`, allowing Corepack to select ambient pnpm 12; the shared scaffolder repair is active and preserves explicit dependency-build approvals. +Bootstrap repair (2026-10-10): generated projects now pin the shipped `pnpm@10.25.0` before dependency installation, including both omitted and present local-package overrides. The build-script allowlist is unchanged. The new regression fails on the original source (missing `packageManager`); the repaired full scaffold suite passes 68 tests. Focused scaffolder TypeScript and Biome checks pass (two existing complexity warnings), and the scaffolder build passes. The actual Node 20/Corepack consumer rerun is pending the laptop thermal guard; AC-1, AC-2 and runtime phase boxes remain open until their required proof exists. + +Parent bootstrap integration: all 68 scaffold tests pass on dde88e30c; scaffolder and assets builds pass, including declarations and package lint. The full consumer retry progressed beyond the earlier pnpm failure but stopped before gameplay: assets now depends on terrain, which the existing game-handoff tarball set does not supply, causing a registry 404. PRD-583 is wiring that local dependency closure. The game stage was not skipped; consumer and CI acceptance remain open. + +2026-10-10 parent consumer repair verified: after integrating the PRD-583 terrain tarball/override closure and baking the required default forest fixture, the full unskipped consumer passes (exit 0). Packed-game scaffold, install, build and WebGPU playtest report NVIDIA Turing; the stock forest loader checks 4 820 placements with zero per-tree copies. This closes the consumer bootstrap failure; the separate showcase runtime budgets and real-CI acceptance remain open. + +2026-10-10 CI status explained: workflow `ci.yml` intentionally gates the scope job on `!github.event.pull_request.draft`. Exact candidate 5ad00f9bc therefore has skipped run 38088798294 and 33 skipped checks; the wait helper's exit 0 is not runtime evidence. The EPIC remains a draft while the full batch is implemented; real CI acceptance stays open until qualification. + +2026-10-12 GPU budget investigation (NVIDIA Turing, headless private Xvfb, host load 4 to 12). The `maxViewGpuMs` budget (12 ms) stays red at 32 to 34 ms and is not fixed. What was measured: all the cost sits in the world-pass bucket (`gpuOther` 23 to 32 ms), while `desert:overview` draws 12 meshes and 1 M triangles. Turning off the post stages (`?off=ambientOcclusion,traa,grade`) moved the worst view 33.76 to 32.31 ms. Hiding the cloud dome, sky, props or water produced no repeatable change. Hiding the terrain (ground plus 786 k-triangle distant ridges) dropped mesa and overview from 24 to 33 ms to 10 to 14 ms. A read of `src/render/terrain.ts` counts about 81 texture fetches and about 160 noise calls per ground pixel. A candidate patch (hoist the UV warp, skip the near block on far ridge rings) compiled, but at a pinned `resolutionScale` of 1 it showed no gain (mesa 32 to 37 ms against 14 to 15 ms on HEAD, with identical HEAD runs spread from 19 to 33 ms), so it was discarded. Two limits on this evidence: the game runs `resolutionScale: "auto"`, which moves the scale between 0.61 and 0.72 during a run, and timestamp medians from the private Xvfb swing by 2x between identical runs. A trustworthy before/after needs a pinned scale and a quiet real display. The box stays open. + +2026-10-12 long-task fix, engine layer: `nodeHasReflector` in `packages/core/src/warmup.ts` walked shared TSL subgraphs once per path to them (no visited set), about 600 ms on the strata scene. The core warmup spec gained a red-first diamond-graph test (20 shared levels, 2^20 `getChildren` calls before, 21 after; 34 of 34 pass). With the fix, the desert world's longest load task fell from 835 to 944 ms to 191 to 228 ms (`afterFirstFrameTaskMs` 0, under the 250 ms budget, two runs). The forest world still shows a 915 to 932 ms task after the fix, so `afterFirstFrameTaskMs` stays red until that task is found. Time to ready is unchanged (desert 19.8 to 21.0 s, forest 28.8 to 29.8 s against 15 s). + +2026-10-12 GPU cost attribution at a pinned resolution scale (desert views, 1080p, scale 1, NVIDIA Turing, private Xvfb, host load 3 to 7, three interleaved runs per arm, medians). Baseline player 36.98 ms and mesa 37.73 ms (`gpuOther` 35 to 36 ms). Hiding only the distant ridge mesh changed nothing repeatable, hiding only the ground mesh saved 9 to 13 ms in player and mesa, and the costs are not additive, which fits a cost of terrain pixels times a heavy fragment shader. Knobs: anisotropy 1 saves 8.5 ms (player) and 5.4 ms (mesa), anisotropy 4 saves 3.5 and 8.9 ms, keeping 2 of the 6 ground layers saves 5.9 and 9.4 ms, MSAA 1 saves under 4 ms, and zeroing the UV-warp noise saves under 3 ms. No single appearance-neutral change gets near the 12 ms budget: stacking anisotropy 1 and a 2-layer ground would still leave about 20 ms. The route the PRDs already name is PRD-591 AC-4, ground plumbing through the engine's splat loader, which replaces the 81 fetches per pixel with a baked splat. That is a large change with a visual-judge gate, so `maxViewGpuMs` stays red and its boxes stay open. + +2026-10-12 weight-gated ground fetches, tried and rejected. A candidate wrapped each ground layer's albedo and relief fetches in an `If` on the layer's maximum blend contribution, using explicit-gradient sampling from the warped UVs (sample sites per pixel 71 to 31 with four inactive overlays). At a pinned resolution scale of 1 on NVIDIA Turing, three interleaved runs per arm: desert player 33.52 to 30.65 ms median, mesa 35.14 to 34.29 ms median, below the 5 ms bar, while identical HEAD runs swung from 15.2 to 39.8 ms (the third HEAD run was the fast one in this and earlier A/B sets, which points at GPU clock or power state, not the shader). Picture check: desert views stayed within noise (mean absolute RGB error up to 0.037), but the forest terrain visibly darkened (mean error 16.4 and 34.4% of pixels over 8, against a HEAD-to-HEAD floor of 1.5 and 6.7%). Reverted, nothing committed. Conclusion for the `maxViewGpuMs` box: fetch-count cuts do not show a reliable gain on this measurement setup, and a trustworthy before/after needs a quiet real display with locked GPU clocks. The box stays open. + +2026-10-12 forest destroyed-texture errors, not reproduced. A capture of the forest at the default look logged 19 `Destroyed texture [Texture (unlabeled 1920x1080 px, TextureFormat::RGBA16Float)] used in a submit` errors, all while the auto resolution scaler sat at 0.85. Five attempts to make it happen again logged zero errors: forest pinned at 0.85 from boot, forest with one forced step 1.0 to 0.85 after warmup, coastal with the same step, forest with the frame-budget callback plus views, and an instrumented automatic run through several steps. GPU tracing found no stale sampled-texture reference. No code changed. The cause is unproven, so the capture lane keeps its zero-console-error assertion and the next occurrence should be saved with its console log. + +2026-10-12 runtime-budget hypothesis (source `8b0c3cf9c`): NVIDIA startup trace attributes 7,346 ms self time over 90 seconds to Three's instance-history `updatePrevious`, alongside 7,525 ms attribute upload. The engine tracker already preserves unchanged history; the adapter still copies and marks it dirty every draw. Smallest candidate: cache the last scheduled source identity and current matrix version per existing history record, keeping moving/unscheduled history and draw ordering unchanged. Expected mechanism result: zero repeated history uploads for unchanged scheduled draws after initial commit; no end-to-end speed claim until paired runtime and visual checks. Regression `instance-velocity-upload.spec.ts` first fails on the actual renderer path (extra upload at line 175). Budgets and scenarios remain unchanged. + +Instance-history candidate verification: first guard also suppressed direct dynamic-array history when matrices changed without a version bump; a second renderer-path regression reproduced that defect. The guard now applies only to engine-scheduled snapshot arrays, retaining Three's raw-array copying. All **71 tests across six focused files pass**, core typecheck and scoped Biome/diff checks pass. The shipped `temporal-aa` browser conformance case passes on NVIDIA/Turing (3.2 s, nonuniform 1280×720 capture, no page or GPU validation errors); runner exit 2 reflects 105 unselected rows, not whole-matrix success. Desktop on existing wgpu host SHA `b756382651baf8347434bdde63cae1b789d126f24f65d2c58ee11e16811ce23e` fails with `wgpuQueueSubmit: Buffer with '' label is still mapped`; the identical case against the prior adapter fails with the identical error and host hash. This is a reproduced baseline native-host limitation, not a native pass or a reason to waive qualification. End-to-end terrain budget, paired performance and visual acceptance remain open. + +The alternative existing Dawn host (`tn-linux-contracts-physics`, SHA `5bc3ecb8abca0c797f8d2ed126b931b9c96a2f8fa4a593b3093e2e7e35e09648`) completes 300 frames and produces a capture but reports repeated submit-while-mapped GPU validation errors; the conformance case fails. No further equivalent native retries are warranted. This corrects the assumption that switching the existing backend is sufficient; current-host temporal buffer qualification remains open. + +2026-10-13 local gate repair: an instrumented repeat reproduced an unhandled `ECONNRESET` from the editor-document test's `ClientRequest._flushOutput`, after its 413 response was already read and the fixture moved on to teardown. Waiting for writable finish timed out because an early rejection can stop that upload. The shared status helper now cancels the remaining request write and awaits its close before returning the observed status; response errors still reject. All four callers retain their original status assertions, including the 10 MiB chunked request. Twelve consecutive instrumented editor-document runs pass 216 assertions with no reset or unhandled error. Server middleware and body limits are unchanged; this is test-client resource ownership, not a suppressed runtime diagnostic. Real CI Strata/editor/consumer proof remains open. + +2026-10-13 qualification repair: the first complete unit phase passed 10,626 tests but failed ten assertions in eight files. Focused reruns now pass all 134 assertions across eleven files. Repairs preserve the gates: the startup fixture supplies a nonempty authoritative manifest missing the requested world; timestamp windows count 300 presented frames on live clocks; the vegetation fixture uses the already-shipped tree-mesh guidance phrase; the core appearance guard ignores type-only re-exports while still scanning world runtime code; the two editor-conflict fixtures are indexed; `transformedLandform` has a generated capability summary; starter-only core/physics imports are declared optional peers. The save queue now uses the existing authoring document and snapshot types instead of duplicate shapes, removing thirteen double casts; its transaction type requires either commands or a document. The prepared-GLTF boundary retains validation while treating incoming JSON as partial until its required asset is checked, and the worker declares its actual global interface. Terrain and assets typechecks pass; focused Biome passes with existing complexity warnings; quality JSON passes without new suppression waivers. The complete unit rerun is pending; no CI or performance box is advanced by these repairs. + +Qualification follow-up: updated full typecheck and lint pass on the laptop; all 317 terrain tests and strict publint pass there. Local affected terrain/assets builds and documentation links pass. An accidental overlap between an assets rebuild and a unit run removed the encoder while tests were reading it; that invalid run was interrupted. After builds completed, both affected files pass all 88 assertions. The sequential package-test phase then passes, and the full unit phase passes 10,634 tests with only two release metadata failures (20 skips); its temporary-directory guard passes 1 → 1. Optional internal peers now use the existing published range `>=0.3.4 <0.4.0`, and the release fixture checks both internal peers advance while external peers remain unchanged. Release/preparation/externals rerun passes 32 assertions; frozen install and strict terrain publint pass. The final complete unit rerun remains pending. + +Final qualification result: the complete unit phase passes **798 files, 10,636 tests, 20 skips** (three skipped files), exit 0; the temporary-directory guard remains 1 → 1. Command: `TN_SUITE_PHASES=unit taskset -c 0-3 nice -n 10 pnpm test`, Node 20.19.6. Four available CPUs select three workers through the unchanged Vitest configuration; assertions and timeouts are unchanged. Duration 848.45 s. Unrestricted parallel runs twice hit the unchanged 60-second build-exit ceiling under host load above 60; the same focused case passes in 29.64 s with this allocation, and the complete bounded board passes. The sequential package-test phase, updated full typecheck/lint, frozen install, strict terrain package validation, and documentation links also pass. Full hosted CI and Strata runtime/performance acceptance remain open. + +2026-10-14 actual CI qualification: [run 38505692929](https://github.com/ThreeNativeHQ/threenative-engine/actions/runs/38505692929) executes the complete selected board on candidate `8f74c3314` (PR head `3d30e3164`). All four unit shards, typecheck, lint, browser/native tests, integration receipts, build and nonvisual templates pass. Strata fails during its web scenario with device-loss errors and resource assertions; consumer/editor steps are therefore not proven by this run. Both golden templates fail during scaffold install because the dlx-local terrain mapping does not propagate to the child project install (npm 404). Package tests independently expose a test dependency on pre-staged scaffolder terrain kits. Bounded repair preserves the existing pnpmfile into child installs through npm_config_pnpmfile and gives the archive test its own authored kit fixture; 35 focused tests pass, including a red/green child-environment regression. Real scaffold installs using the exact CI tarballs now pass for both starter and platformer (ordinary dependency scripts enabled, no install bypass). Both installed games also pass ordinary build:web. The repaired full terrain package test passes all 317 tests and strict publint; documentation checks pass 3,122 links across 1,375 Markdown files. Their complete golden runtime journeys still need rerunning. Desktop conformance has one failing row, virtual-shadow-first-frame (pixel mismatch 0.012477 > 0.01, no GPU errors); no thresholds were changed. CI/runtime acceptance remains open. + +2026-10-14 runner prerequisite isolated: GitHub job API confirms the failed Strata leg used hosted ubuntu-24.04 (runner GitHub Actions 1000083106), and repository variable TN_RUNNER is absent (GET 404). Read-only runner/source inspection finds no registered hardware-GPU lane: the existing tn-local pool uses containers without GPU passthrough. The reported SwiftShader adapter is therefore consistent with the selected lane; it is not evidence of hardware rendering or a source-level explanation for device loss. A dedicated hardware lane is required before this CI result can prove the intended adapter and runtime budgets; changing shared TN_RUNNER would also reroute unrelated work and was not done. Cheap-arm triage completed, but its claimed event order and empty parity metrics were rejected against primary artifacts. Native parity capture analysis finds 11,499 changed pixels; only 11 exceed one RGB level (maximum 94), so the 0.012477 mismatch remains a real failed strict gate requiring investigation, not a tolerance change. Full golden journeys on the laptop initially stop at its ambient Corepack pnpm 12 launcher before scaffold; verified pnpm 10.25.0 is now supplied on a job-local PATH for the retry. No global tool or runner configuration changed. + +2026-10-14 full-journey follow-up: pinning the laptop job to verified pnpm 10.25.0 exposes a second local-source closure failure: initial scaffold installation passes, but the golden journey's independent `pnpm install` requests terrain from npm again. The shared scaffold helper now copies its existing local mapping into the generated project as `.pnpmfile.cjs`, retaining pnpm's ordinary discovery for later installs and corrective commands without adding terrain as a direct game dependency or changing global configuration. The new regression fails before this copy; all 24 golden-path tests and scoped Biome pass after parent review. A real starter scaffold followed by a separate ordinary install succeeds against the exact CI tarballs; its lockfile resolves terrain to that local archive. The complete laptop retry progresses into gameplay, with starter-area-monitoring and starter-deferred-motion-odometer scenarios passing without diagnostics. Remaining scenarios and the platformer journey are still running; no full-journey tick yet. + +2026-10-14 full golden retry outcome: scaffold, independent install, MCP discovery and dev startup pass. Starter passes 23 scenarios; `play` fails its unchanged maxFrameMsP95 ceiling (52.4 ms observed, 33 ms allowed, 200 samples) on real Intel gen-12lp WebGPU. The harness removes its temporary game after failure, so a separate retained starter was recreated from the same CI tarballs and built once for two isolated `play` reruns. Both CLI runs exit 1: p95 43.8/48.8 ms, 197/200 samples. Retained probe: `/tmp/pr483-starter-p95-rLim6Q/starter` on the laptop. No performance code or thresholds changed. Full golden and Strata acceptance remain open. + +Comparable baseline: exact develop `5f7143895` CI run 38486297491 tarballs (artifact 11859288115), with no candidate archives mixed in, generate hash-identical starter `src/`, config and `play` scenario. Two baseline runs also fail only maxFrameMsP95: 44.2/53.3 ms, 199/201 samples, against 33 ms. Both arms use Intel gen-12lp WebGPU, 1920×1080, resolution scale 1, MSAA 4 and completed startup warmup. This reproduces the failure on the base revision; its cause remains unknown. These fixed-step scenario observations do not establish steady-state FPS. Baseline retained at `/tmp/pr483-starter-baseline-OScm7M/starter` on the laptop; no acceptance box closes from this comparison. + +2026-10-13 platformer full-journey attempt: laptop offload exits 75 before launch at 97–100°C; zero stages or scenarios ran and no game was created. Other lanes own the running GPU work and were left untouched. Separately, the Strata CI observations include waveSamples 0 and measuredGpuViewCount 0 alongside software-adapter/device-loss diagnostics; neither this payload nor the timed-out read-only triage establishes the source-level cause. Full runtime acceptance stays open. The batched bootstrap and native fixture-policy repairs pass their focused checks and ci:fast; publication waits for the shared CI board slot currently held by PR488. + +2026-10-13 platformer retry completes: `pr483-platformer-full-r2` exits 0 after laptop temperature drops to 48°C and its GPU lock becomes free. Using the exact candidate CI tarballs with the repaired golden helper and verified pnpm 10.25.0, the ordinary full platformer journey passes scaffold, independent install, MCP discovery, dev startup, every gameplay scenario, web build and artifact assertion on Intel gen-12lp hardware WebGPU. The existing mutated-package control rejects its deliberately missing Vite archive as expected. No software-mode or scenario cap was set. This closes the local platformer journey retry, not Strata or fresh CI qualification. diff --git a/docs/PRDs/strata-terrain-hardening/PRD-591-the-preview-stops-reimplementing-engine-mechanisms.md b/docs/PRDs/strata-terrain-hardening/PRD-591-the-preview-stops-reimplementing-engine-mechanisms.md new file mode 100644 index 0000000000..572a3b8dbe --- /dev/null +++ b/docs/PRDs/strata-terrain-hardening/PRD-591-the-preview-stops-reimplementing-engine-mechanisms.md @@ -0,0 +1,177 @@ +# PRD-591 — The preview stops re-implementing engine mechanisms + +**Status:** PARTIAL +**Priority:** P2 — A second prop LOD pipeline, a spawn-readiness gate and the scatter loop stay in example code where every terrain game must copy them (AC-1 to AC-4). +**Complexity:** 6 (MEDIUM); risk override: visual output changes, so the owner's visual-judge rule applies +**Owner:** ThreeNative maintainers +**Depends on:** [PRD-585](PRD-585-strata-proof-runs-in-ci.md) (the CI job guards the moves) +**Epic:** [Strata terrain hardening](README.md) + +## Context + +Example audit of `2d2124792` (2026-10-10), `examples/strata-terrain-preview/src/render/`: + +- `props.ts:119, 627, 798-897` hand-writes an LOD ladder (`LOD_BANDS`, `levelFor` with + hysteresis, `setLevels`, one `InstancedBatch` per variant, level and role).

The editor viewport is pixel-identical in four views (mean absolute RGB difference below 2e-6, 0% of pixels over 8; 100 placements, 200 parts, 390,800 triangles each), so no pixel reached the screen differently and no visual judge ran. 88 of 88 preview tests pass; typecheck and Biome pass; `count-loc.ts --check` passes. `check-temperate.mts:45` keeps one tree-scale assertion that already failed before this change, and its streamed section passes on its own. +- [x] AC-2 [local]: `WorldCells.whenSpawnReady` gates the preview's spawn, and the example's readiness module is deleted. proof: `pnpm exec vitest run packages/core/__tests__/world-cells-data.spec.ts` plus `test:terrain:web` Evidence: 2026-10-12, NVIDIA Turing, private Xvfb. `spawnReadinessSnapshot` and its helpers are deleted from `render/loading.ts` (112 lines) and prop streaming's `readinessAt` and `ready` are gone (22 lines); `game.ts` gates on `WorldCells.whenSpawnReady(spawn, 60)` for nearby prop cells and on prewarm for drawing, and terrain plus its collider exist before preparation starts. Seven files, 147 added and 263 removed (net -116). A deliberately premature gate failed the new regression in `world-cells-data.spec.ts` and `strata-loading.spec.ts`, then passed; terrain and preview suites pass 445 of 445. Forest `test:terrain:web` is 41 of 44 before and after: the only failures are the known budgets `afterFirstFrameTaskMs`, `timeToReadyMs` and `maxViewGpuMs`; the spawn assertions pass (6 of 6 spawn cells, grounding, empty loading error). +- [x] AC-3 [local]: Scatter runs in the bake, and `enter` does no scatter work. proof: `test:terrain:web` asserting no long task over 50 ms during `enter` Evidence: 2026-10-12, NVIDIA Turing, private Xvfb, forest, two runs per arm. Measured phases of the old `enter` (ms, run 1 / run 2): terrain mesh 272 / 286, `scatterProps` 355 / 353, `paintCanopy` 7.5 / 7.6, fallback variants 72 / 69, setup, sky and rivers under 40; `enterMs` 764 / 782. Scatter and canopy now run in `scripts/bake.mjs` and `enter` loads a Float32 placement table per world (`src/world/.placements.bin`, gitignored like the other baked world files, regenerated by `pnpm bake`, which `dev` and `build` run; sizes forest 8.1 MB, coastal 5.5 MB, tundra 1.7 MB, alpine and desert 0.4 MB; zero tracked binary growth). Placement lists, order, counts and `paintCanopy` arrays are SHA-256 identical to HEAD in all 5 worlds. After: forest `enterMs` 34.8 / 35.1 ms (forest-scoped runs). Re-measured on the full `test:terrain:web` scenario (all five worlds, six visits): coastal's `enter` was 218 ms (first visit) and 137 ms (return) because the water mesh was built inside `enter` (106 / 159 ms). `load()` now prepares the ocean and water mesh and `enter` only attaches them (`game.ts`, +8/-4). After, one full run: `enterMs` was 10 to 45 ms in every visit (largest 45 ms, so the 50 ms assertion has a thin margin under load) and the `enterMs` assertion passes; the arm's own first candidate run crashed the page while another process held 8 GB of RAM and did not reproduce on the rerun, so treat the fix as one clean full run. Failed assertions: only `afterFirstFrameTaskMs`, `timeToReadyMs`, `maxViewGpuMs`; no `diagnostics` failure and no destroyed-texture errors in that run; `component.player.visible.value.atSteps` passed (it failed in two earlier loaded runs and passed in two others, so it is load-dependent). Coastal player view before/after mean absolute difference 0.1 against a noise floor of about 2.0. Not improved: `afterFirstFrameTaskMs` went 482 / 488 to 597 / 787 ms and `timeToReadyMs` 27.1 / 26.3 to 28.4 / 27.1 s, both still failing their budgets (the host was loaded, so read these as no gain, not as proof of a regression); the largest remaining single tasks are in `buildProps` (asset load 351 to 378 ms, surfaces 131 to 136 ms) and the terrain mesh build (272 to 286 ms). `maxViewGpuMs` unchanged.

Caller migration and full runtime/visual acceptance remain open. + +2026-10-12 coastal stone contact: the remaining thin tan rim is removed by explicitly casting the front-facing stone surface in both procedural and imported coastal material paths (four added lines in `propMaterials.ts`/`pack.ts`). CPU rays through the actual transformed fallback rock confirm terrain contact and sunlight obstruction; AO-off, haze-off and MSAA-off probes leave the defect unchanged. Two exact-pose BEFORE/AFTER headed WebGPU runs report NVIDIA/Turing. Fresh read-only visual judge: **IMPROVEMENT for pair 1, pair 2 and overall**; the tan underside contour disappears with texture/top shading retained and no visible new acne or halo. The deepest contact pixels merge into shadow, and AFTER 1 is sharper globally; pair 2 independently supports the contact improvement. Imported coastal materials receive the same override but were not visually captured. Existing material/LOD/shadow specs pass 35/35; scoped Biome and diff check pass. The full terrain scenario completes with 60/63 assertions passing; the existing three runtime budgets fail (see run below), so this does not close the five-world AC-5 gate. + +Judged captures, pinned on orphan `strata-hardening-screenshots` commit `0611cc9809b287eac1b0969934e5f799ed082305` (all four public URLs return HTTP 200 and byte-match the captures): [BEFORE 1](https://raw.githubusercontent.com/ThreeNativeHQ/threenative-engine/0611cc9809b287eac1b0969934e5f799ed082305/pr483/stone-shadow-side-before-1.png), [AFTER 1](https://raw.githubusercontent.com/ThreeNativeHQ/threenative-engine/0611cc9809b287eac1b0969934e5f799ed082305/pr483/stone-shadow-side-after-1.png), [BEFORE 2](https://raw.githubusercontent.com/ThreeNativeHQ/threenative-engine/0611cc9809b287eac1b0969934e5f799ed082305/pr483/stone-shadow-side-before-2.png), [AFTER 2](https://raw.githubusercontent.com/ThreeNativeHQ/threenative-engine/0611cc9809b287eac1b0969934e5f799ed082305/pr483/stone-shadow-side-after-2.png). + +Full terrain rerun (2026-10-12, stone source `60e16086d`, headed NVIDIA/Turing): the official `terrain.playtest.json` completed with **60/63 assertions passing**, exit 1. Console/network/runtime-diagnostic policy passes. Open budget failures are `afterFirstFrameTaskMs` 2,273 >250 ms, `timeToReadyMs` 52,877.5 >15,000 ms, and `maxViewGpuMs` 47.92 >12 ms. Navigation/server deadlines were 120/600 seconds to permit infrastructure startup; assertion budgets were unchanged. This full failure remains acceptance work, not a green scenario claim. Existing harness artifacts: `examples/strata-terrain-preview/artifacts/playtest/web`; exact output `/tmp/pr483-final-terrain-web.log`. + +Startup attribution (2026-10-12, source `4dd84d084`): shipped `playtest trace --no-wait --settle 0.001 --seconds 90 --no-input --stall-ms 250` captured 342,821 events on NVIDIA/Turing. Host display `:0` was unavailable; the diagnostic used private headed Xvfb, so frame rate is suppressed and the CLI correctly exits 1 (`TN_TRACE_VIRTUAL_DISPLAY`). This is function attribution, not acceptance or a performance win. Fifteen main-thread tasks exceed 250 ms, largest 1,608 ms. Across the sampled 90,234 ms, `updateAttribute` uses 7,525 ms self time and Three's instanced `updatePrevious` 7,346 ms; graph child traversal and bundle-safety snapshots are also material. These whole-window totals do not identify the single startup task's cause; inspect individual long-task stacks before choosing a fix. No budget, render stage or quality setting changed. Raw diagnostic: `/tmp/pr483-startup-trace.json`; summary is in the local long-running-task cache. Scene doctor separately reproduces non-finite `entities[1].bounds.height`; exact object/projection instrumentation is pending. + +Ground-loader prerequisite (2026-10-12): `ITerrainSplatLayer.maps` now accepts optional package-relative diffuse, normal, ORM and height paths, preserving existing filename defaults and presence flags. This lets the preview reuse its current `_diff_1k.jpg` / `_nor_gl_1k.jpg` maps without duplicate image aliases. Explicit null/malformed paths or containers reject, and missing explicit maps propagate failure without fallback. The existing `terrain-splat-array` conformance fixture exercises all four overrides with unchanged image data. Actual-source tests reproduced the path mismatch before the change; the parent rerun passes 29/29 focused loader tests. Core TypeScript, fixture syntax and scoped Biome pass (one existing unrelated complexity warning). Browser/native fixture execution is pending. AC-4 remains open: bake/Vite/native staging must emit the real descriptor/table/raw splat, and the consumer must reuse the engine blend while preserving game-authored sampling and measured height bands. No preview material or assertion budget changed in this prerequisite. + +Explicit-map execution (2026-10-12, loader source `17e6dec78`): the selected `terrain-splat-array` case passes in browser on NVIDIA/Turing at 1280×720 (nonuniform capture, no page or GPU validation errors) and on the existing desktop wgpu host for 300 frames (native exit 0, no GPU validation errors). Desktop image comparison: pixel mismatch 0, perceptual delta E 0. Runtime SHA-256 `b756382651baf8347434bdde63cae1b789d126f24f65d2c58ee11e16811ce23e`. Both bounded harness invocations exit 2 because 105 unselected cases remain blocked; these are selected-case passes, not full-matrix qualification. The first desktop invocation executed no case because its default browser-reference directory was absent; passing `--reference` to this same run's browser captures resolved that prerequisite. Existing reports: `packages/runtime-native/artifacts/strata-splat-paths-{web,desktop}/report.json`. Parallel uncommitted bake work is recorded as dirty provenance; it does not enter this fixture. AC-4 remains open. + +Ground-package export (2026-10-12): the bake now emits one minimal surface-loader descriptor, layer table and two-plane raw RGBA8 mask per biome; all eight evaluated material channels are preserved with the loader's (x, -z) row orientation. Existing map paths and the current CC0 fallback for optional licensed rock maps are reused without duplicate image files. Vite and native staging deliver the same 20 surface/placement files. Three focused packaging contracts pass, including real painted Terrain weights, map existence, source-array preservation, malformed mask rejection and missing-file failure. The parent real bake first exposed new static TypeScript imports resolving before the tsx registration; awaited imports fixed that entry failure. A fresh full five-world bake passes in 24.29 seconds, and all ten checked pre-existing world/placement files remain SHA-256 identical. Preview build passes (Vite 6.74 seconds); actual browser dist and native staging each contain 20 byte-identical files. Each biome's raw mask is 528,392 bytes. Combined loader/export tests pass 32/32, script syntax and scoped Biome pass (two existing complexity warnings). Generated raw masks are ignored like the existing baked JSON and placements. Runtime ground material still uses its prior path; AC-4/AC-5 remain open. + +Ordered-blend prerequisite (2026-10-12): optional `layerSample` and `materialFactory` callbacks let game-authored projection and final material assembly reuse the loader's existing ordered colour/normal/ORM blend. Samples are precomputed before weight callbacks; custom sampling skips array stacking and reports a loaded-sampler upper bound rather than pretending to measure shader bindings. Callback-loaded textures are owned until material disposal, with idempotent cleanup on composition errors and late asynchronous completion; factory-only stacked sources are not disposed twice. Parent focused loader tests pass 36/36, including actual node-graph ordering, unchanged defaults, channel fallback and failure/disposal cases. Core TypeScript, build/publint and scoped Biome pass; Biome reports a new complexity advisory in the loader and the existing traversal advisory. Browser/native execution of the callbacks, preview consumer migration, measured height bands and five-world visual acceptance remain unverified. No acceptance box is closed by this prerequisite. + +Preview consumer migration (2026-10-13): `createGroundMaterial` now loads the real baked world/layer/mask package through `loadTerrainSplat`; game callbacks retain existing projection, relief, geometric placement curves and final lighting while core owns the ordered colour/normal blend. The duplicate consumer blend loop and image-set loader are removed. Geometry-derived weights intentionally override the package mask curve; no claim is made that the baked mask determines the current procedural look. Optional owner-local rock maps retain the portable CC0 fallback and separate disposal ownership. Actual-source consumer tests exercise absent/present licensed maps and image disposal. A new cancellation regression first fails when terrain disposal precedes asynchronous maps, then passes with a geometry-disposal guard preventing late attachment. Parent combined packaging/loader rerun passes 42/42; example TypeScript passes. Worker scoped Biome passes with five complexity advisories. Browser/native rendering, measured height bands and paired five-world visual verdict remain open; this tested source slice does not close AC-4 or AC-5. + +Normal pre-push repair (2026-10-13): the first push fails `ci:fast` on stale complete-scaffold hashes and lint. Read-only comparison isolates the thirteen scaffold changes to the regenerated canonical Three patch copied into every kit; expected hashes are refreshed from all thirteen actual trees while preserving the full-tree equality assertion. The focused scaffold contract passes (one selected test, 67 unselected). Generated native `assets/world/*.json` copies now share the existing generated-source JSON formatting exclusion; semantic export/staging tests remain active. Inherited donor gait keys retain their exact external spelling by quoted literals and an exact-file quote-preservation formatter setting. Naming and literal-key rules remain enabled; all other donor AST nodes, values and references are identical after parsing. Scoped Biome passes for these three files. Full normal hook rerun and push remain pending; these repairs are not full CI acceptance. + +Measured elevation bands (2026-10-13): each loaded scene now measures its actual finite height samples once and shares a fresh readonly biome clone with ground, imported stones and procedural stones. Authored fractions and resolved metre bands have separate types/fields; no world-key cache can leak across cancellation or reloads. Flat worlds retain their actual equal min/max and emit constant finite elevation weights, with no invented metre range. Empty/nonfinite samples and overflowed extrapolated bands reject. Actual-source RED tests reproduce the old alpine graph's fixed 50/180 thresholds and the finite-input overflow case; parent final tests pass 54/54 across surface/LOD/package contracts, plus example TypeScript and scoped Biome (19 complexity advisories). Scale-and-offset tests inspect actual snow-node constants and independent snapshots. Alpine snow now resolves from .60–.85 of its 1.20–654.50 m range to 393.18–556.505 m; tundra .15–.45 resolves to 16.515–30.945 m. Temperate fractions above one deliberately reserve snow for the distant horizon; forest/coastal snow stays approximately 145–195 m. Desert's snow remains disabled. Existing metre-scale shelter/noise offsets remain authored appearance choices. GameState exposes measured min/max and resolved snow bounds for runtime assertions. No paired five-world judgment or native callback rendering has run for this source yet; phase 3 and AC-4/AC-5 remain open. + +2026-10-13 actual callback GPU proof: the existing `terrain-splat-array` case now renders a small offscreen three-layer probe through both custom callbacks before its unchanged visible sixteen-layer default scene. Its exact oracle checks callback-scaled albedo, encoded normal, ORM and authored mask populations (8 base, 4 layer zero, 4 layer one), with only one-byte quantization tolerance. Four single-row reads avoid Three's padded multi-row buffer representation. The first actual browser runs exposed and corrected the readback-layout and mask-population assumptions without widening the oracle. The selected headed WebGPU case now passes on NVIDIA/Turing at 1280x720 with no page/GPU errors (`strata-splat-callback-web-fixed/report.json`); CLI exit2 reflects 105 unselected blocked rows, not a full matrix pass. The cached August wgpu host fails the new readback with zero pixels and its known still-mapped-buffer queue-submit panic; native acceptance remains open while the current canonical Dawn host builds. Fixture syntax and scoped Biome pass. + +2026-10-13 five-world AFTER attempt: the first sealed measured-band run captures forest, coastal and alpine, then loses its WebGPU device during the subsequent switch and renders blank desert frames. The saved console first reports an invalid external instance, then unknown device loss and downstream timestamp/readback errors; no evidence establishes that query resolution caused the loss. The owned run is stopped with exit130 and retained for diagnosis. Later DevTools/window changes invalidate its calibration, so none of this run closes the paired visual or runtime acceptance. Both sealed BEFORE runs remain valid and labelled. A bounded cold alpine-to-desert diagnostic now retains Chromium process stderr; no acceptance budget or readiness check changed. + +2026-10-13 current native callback correction: the canonical default Dawn + V8 v0.3.4 host builds successfully in 8 min 32 s, SHA256 `59b3ec63dad29db0c1b0938e241064a7846fc63b9171e2d927874e6301f899f9`. The exact selected callback case now passes on this host: 300 frames, native exit0, 1280x720, pixel mismatch0, perceptual deltaE0 and no GPU validation errors (`strata-splat-callback-desktop-current/report.json`). The wrapper CLI exits2 for 105 unselected blocked rows. This supersedes the cached August host's callback failure, without accepting a full native matrix. Both callback hooks therefore have actual browser and desktop proof; full preview/visual acceptance remains open. + +2026-10-13 regression isolation: the bounded cold alpine-to-desert case passes against the pinned953 baseline with nonblank 2.27MB/1.60MB frames, but fails against the pinned e2e candidate with blank8517B frames and WebGPU device loss. Chromium stderr confirms an unexpected GPU-process exit512 on the candidate. The readable kernel journal establishes no OOM/Xid event in that interval; a later low-memory snapshot cannot exclude an earlier peak. Existing pipeline census records candidate ground fragment121014B versus baseline118896B, so shader-size explosion is not established. Source-specific regression investigation now captures generated shader code in diagnostic copies; no repeated full AFTER run or acceptance claim. + +2026-10-13 timing-sensitive diagnostic result: the sealed953 baseline and sealed e2e candidate both pass the cold alpine-to-desert route when the same synchronous shader-source logging hook is installed in diagnostic copies (74frames, all nine assertions, nonblank alpine/desert frames). All61 shader sources per arm match their own pipeline-census hashes and byte lengths. Main-ground bindings and texture-sample counts are unchanged; graph changes include vec3 color intermediates, duplicated inline noise and a constant-valued macro term. None establishes a shader bug. These diagnostic passes do not erase the two uninstrumented candidate failures or close preview acceptance; a forwarding-only versus logging-hook comparison will test timing sensitivity before any product fix. + +2026-10-13 recovered full AFTER run1: the unchanged sealed e2e preview completes the entire five-world scenario with all assertions passing and zero optional404 errors. Parent validation confirms15 distinct nonblank poses on NVIDIA Turing1920x1080,657 calibrated surfaces at scale1/MSAA4,60 zero streaming queue counters and60 elevation/snow observations matching the sealed heightfields and measured biome policy. All15 images are labelled in review-after-1. The pure-JSON validator and actual generated heightfield paths were repaired without weakening its checks. This establishes the completed run; earlier device-loss failures remain retained and unresolved. Run2 and the independent paired visual verdict remain open. + +2026-10-13 second recovered full AFTER capture passes all15 poses,654 calibrated scale1/MSAA4 surfaces,60 queue observations and60 elevation/snow observations; no console errors. Fresh independent review of all60 BEFORE/AFTER images returns REGRESSION for every alpine pose in both pairs; other worlds are NEUTRAL or IMPROVEMENT. The original visually rejected measured-height candidate remains unaccepted. One separate alpine exceedance-coverage experiment passes24 focused unit tests; two actual capture runs and fresh judgment remain pending. Earlier cold-transition GPU process failures remain unresolved despite the later complete captures. + +2026-10-13 alpine exceedance-coverage experiment is rejected and its two tracked files restored to the committed candidate. Both three-pose runs validate NVIDIA Turing1920x1080, scale1/MSAA4, twelve settled queue observations and twelve measured-band observations; diagnostics fail on84 console404 errors per run, with source URLs unobserved. Fresh independent review of all12 images returns REGRESSION overall: player view regresses in both pairs, close and overview are NEUTRAL. The assumption that the proposed scalar coverage fractions preserve coherent lower-slope snow is unsupported; no further equivalent quantile tuning or visual acceptance is claimed. Rejected source, seals, raw captures and labels remain isolated under artifacts/alpine-snow-coverage. + +2026-10-13 bounded GPU attribution remains incomplete: final diagnostic joins119/120 required frame identities and fails closed, while the observer resolves120 frames/1320 queries with zero queued, pending, undrained or dropped counts. The last pass identity is missed after the diagnostic stop fence. For119 complete rows only, total GPU p50/p95/max is16.77/19.65/21.28ms; the shared scene-camera1920x1080 single-sample offscreen query averages15.46ms across terrain, props, sky and water memberships. No per-object geometry/instance cost, separate shadow or compute series is observed. This partial diagnosis neither attributes the original47.92ms worst-view sample nor passes the12ms budget. Further equivalent diagnostic reruns are parked. diff --git a/docs/PRDs/strata-terrain-hardening/PRD-593-the-three-patch-is-generated-and-the-upload-lane-leaves-it.md b/docs/PRDs/strata-terrain-hardening/PRD-593-the-three-patch-is-generated-and-the-upload-lane-leaves-it.md new file mode 100644 index 0000000000..4e8b233a9e --- /dev/null +++ b/docs/PRDs/strata-terrain-hardening/PRD-593-the-three-patch-is-generated-and-the-upload-lane-leaves-it.md @@ -0,0 +1,164 @@ +# PRD-593 — The three.js patch is generated, and the upload lane leaves it + +**Status:** PARTIAL +**Priority:** P1 — #381 grew the hand-maintained three patches by about 11 000 lines on private three internals, so any three upgrade can silently break texture upload for every game (AC-1 to AC-4). +**Complexity:** 6 (MEDIUM); risk override: compatibility — a wrong patch breaks every game's renderer +**Owner:** ThreeNative maintainers +**Depends on:** None +**Epic:** [Strata terrain hardening](README.md) + +## Context + +Core audit of `2d2124792` (2026-10-10): + +- `packages/core/patches/three@0.185.1.patch` grew +630/−120 lines and + `three@0.185.1-prd269-upgrade.patch` grew from 5 620 to 15 838 lines.

A separate fresh `--check` build also printed `matched`. +- [x] AC-2 [shared]: CI fails when a patch file is edited by hand. proof: CI job step in `ci.yml` — Evidence: the fail-closed hand-edit control below exits 1 locally; the required generated-patch check ran successfully in [candidate CI](https://github.com/ThreeNativeHQ/threenative-engine/actions/runs/38505692929/job/115662759477) before package publication (2026-10-14). + - Local CI wiring proof (2026-10-11): moved `Verify the generated Three.js patch has not drifted` from `budgets` to `build-artifacts`, before workspace-dist cache restore/build/publication, including develop cache warming. `time pnpm --filter @threenative/core patch:generate --check` reports wall cost and preserves failure; the generator throws on download failure and checks the pinned archive hash. CI caches pnpm, not the fresh upstream archive or its npm build. Clean check: `matched`, exit 0, 54.52 s.

The new placement contract failed before the move and passed afterward; all 12 specs found by `rg -l "ci.yml" scripts/__tests__` passed (458 tests, 20.46 s), including structure, needs, selection and integration receipts. `pnpm check:docs` passed; scoped Biome passed with three existing complexity warnings.

The patch still contains the upload-lane hunks. This PRD stays open. + - Public proof (2026-10-11): `renderer-texture-preparation.spec.ts` passes 43 of 43 tests. The spec now has 35 existing tests and 8 added tests. + - Guards: the planner rejects a mip whose size is not the halved base, and a mip chain longer than the base allows. Both checks run before any GPU allocation. + - The write step rejects an unaligned base unless the device reports `texture-compression-unaligned`. The check runs before `createTexture`. + - Cancellation: a public test rejects a cancelled caller at once and starts the next allocation after every popped scope settles. It passes. + - Legacy proof: `three-compressed-upload.spec.ts` passes 102 of 102 tests. It drives three's internal `Renderer`, `Textures`, and `WebGPUTextureUtils` modules. The patched upload lane is in `Textures.js`. Together, both specs pass 145 of 145. + - Gates: core typecheck exits 0. Scoped Biome exits 0 with three complexity warnings: `planCompressedUpload` (33), `upload` (21), and `writeTiles` (25), limit 15. `git diff --check` exits 0, and the untracked helper has no whitespace findings. + - Earlier work stays in place: source isolation, device and lifetime ownership, and the error-scope drain. A synchronous `check` or `writeTexture` throw now waits for every popped error scope before the lane advances. + - Depth guard (2026-10-11): `compressedLayers` rejects a 2D `CompressedTexture` whose `image.depth` is above 1, before any GPU allocation. In installed three 0.185.1, `CompressedArrayTexture` sets `image.depth`. `CompressedTexture` sets `image` to `{ width, height }` only. + - `renderer-texture-preparation.spec.ts` passes 49 of 49 tests, up from 43. Six tests were added. Only the 2D rejection failed before the guard: `promise resolved "1" instead of rejecting`. The other five pass before and after, so they pin existing behavior. Surplus layer data stays accepted: three depth tests start with four layers at depth three. + - Legacy `three-compressed-upload.spec.ts` passes 102 of 102. Core typecheck exits 0. Scoped Biome exits 0 with the same three complexity warnings. `git diff --check` exits 0 for the spec, and `git diff --no-index --check` prints nothing for the helper. These are mock-device unit results only. No browser, native, visual, or perf run. + - Binding state (2026-10-11): `snapshotOf` compares the binding fields `Texture.copy` carries, except `name` and `userData`, plus `wrapR` and `compareFunction` when present, `source.dataReady`, and matrix elements as numbers. A changed binding starts a new upload. The cached prepared texture stays until that upload commits. + - Binding proof: `renderer-texture-preparation.spec.ts` passes 59 of 59 tests. Before this change, 10 binding tests failed and 49 passed. `three-compressed-upload.spec.ts` passes 102 of 102 tests. Core typecheck exits 0. Scoped Biome exits 0 with the same three complexity warnings. `git diff --check` exits 0, and the untracked helper prints no whitespace findings. These are mock-device unit results only. + - Depth guard, tightened (2026-10-11): a 2D texture accepts only `image.depth` of `undefined` or `1`. Before the change, six new cases failed because the old guard let each value through: `NaN`, `0`, `-1`, `-Infinity`, `0.5`, and `null`. The first failure reported `promise resolved "1" instead of rejecting`. `Infinity` and `1.5` already rejected. Invalid values now get a message that does not name an array class. + - Gates (2026-10-11): `renderer-texture-preparation.spec.ts` passes 69 of 69. `three-compressed-upload.spec.ts` passes 102 of 102. Core typecheck exits 0. Scoped Biome exits 0 with the same three complexity warnings. `git diff --check` exits 0 for the spec, and `git diff --no-index --check` prints nothing for the helper. These are mock-device unit results only. AC-3 stays open. + - Remaining proof: native, browser, visual, perf, and patch. AC-3 needs a WebGPU playtest of the strata preview, and the patch hunks removed, before it can be ticked. + - Native proof, first run (2026-10-11): the selected desktop row failed on the stale wgpu host `build/tn-linux-wgpu/mystral` (v0.3.0, built 2026-08-27, sha256 `b7563826…ce23e`). The full host stdout shows the cause: `[ThreeNative conformance] failed: Error: Device lost during texture preparation.` A probe script on that host shows `device.lost` resolves at once with `undefined`. That host predates the #381 fix in `src/webgpu/bindings.cpp`, which keeps `device.lost` pending. The EGL vendor file was not the cause: the host acquired the RTX 2080 on Vulkan. + - Native proof, current host (2026-10-11): `pnpm native:build` in this checkout built the default Dawn + V8 host `build/tn-linux/mystral` (v0.3.4, sha256 `3377038a…71fadb`) in 5 min 18 s. The selected desktop row `compressed-texture-preparation` passed twice: 22.5 s and 14.4 s. Adapter: `NVIDIA GeForce RTX 2080`, backend Vulkan. `native.completed` is true and `gpuValidationErrors` is empty. The 1280x720 screenshot shows a green upper half and a red lower half on a dark background, which matches the approved web image. The runner exits 2 because 103 unselected rows report `blocked`, so this is not a full-board pass. + - WEB headed setting: `packages/runtime-native/conformance/run-conformance.mjs:807` sets `headless: false`. + - AC-3 stays open. Web and native now pass for the public helper, but the patch still contains the upload-lane hunks, and the strata preview WebGPU playtest has not run without them. + - Upload patch removal (2026-10-11): removed the private `Renderer.prepareTextureAsync` and backend delegation, `Textures.updateTextureAsync`, its serialized promise queue, per-texture abort/loss/disposal handling, and the bounded 2 ms / 64 KiB uploader in `WebGPUTextureUtils`. Removed the `updateTexture` wrapper and its async-only helpers: only `updateTextureAsync` populated `_pendingUploads` and wrote `data.uploadError`, so both wrapper checks belonged exclusively to that lane. Retained bind-group invalidation on texture destroy, the per-sample-count `_depthBuffers` cache, the wgpu-native 3D attachment guard, and all unrelated hunks. Core `prepareTextures` already routed exclusively through `CompressedTextureUploads`; removed its dead private-method declaration and private-method test doubles, preserving the three-argument `Promise` contract and optional fourth replacement map. + Both patches were regenerated only with `pnpm --filter @threenative/core patch:generate`; a second fresh build with `--check` printed `matched`. `wc -l` before/after: base 6,221 -> 5,048; upgrade 230 -> 230; total 6,451 -> 5,278. Installed Three.js matches all 30 generated target hashes, and grep found no `updateTextureAsync` or `_uploadTail` in either installed WebGPU bundle. The replacement guard checks both generated artifacts, the decompressed upgrade payload, and installed source/bundles; it failed against the old lane before removal and passes afterward. + Focused suite passed 104/104 (previously 205/205): `renderer-texture-preparation.spec.ts` 69 -> 69, `three-compressed-upload.spec.ts` 102 -> 1, `three-patch-compat.spec.ts` 9 -> 9, `three-patch-upgrade.spec.ts` 22 -> 22, and terrain `prop-texture-preparation.spec.ts` 3 -> 3. Removed all 102 tests of the obsolete private manager/uploader lifecycle and synchronous private baseline; public upload behavior reuses the existing 69-test spec, including real transcoded mip data. The compatibility expectation now accepts an unchanged predecessor when removing the upload method makes its hash identical to the generated target. Core typecheck and build exit 0; scoped Biome exits 0 with seven existing renderer complexity warnings. + Reapplication exposed two installer limitations: the Phase 1 generated bundle hashes are not registered predecessors, and stock `Batch.js` is misclassified because its deletion-only trailing-blank hunk's new text already occurs in stock. Verified every installed Phase 1 hash, reversed that exact patch to stock, applied the new generated patch with standard `patch` at zero fuzz, and verified all target hashes; the repository apply script then reported unchanged. These installer limitations remain open. No browser, GPU, native, visual, or performance run was performed here; the coordinator owns those runs. AC-3 and Phase 2 stay unticked. + - After hunk removal (2026-10-11, `1b6b0f593`): the selected conformance row `compressed-texture-preparation` passed on web (headed, adapter `nvidia`/`turing`, 3.4 s, no page or GPU validation errors) and on the desktop Dawn host (30.2 s, `native.completed` true, no GPU validation errors). The two screenshots match: green upper half, red lower half. The other 103 rows report `blocked`. + - Strata preview WebGPU playtest after hunk removal (2026-10-11): `terrain.playtest.json`, headed, `--browser-recipe webgpu`, adapter `nvidia`/`turing`, ran to completion in 16 min 23 s with `--server-timeout 600000 --timeout 120000` (the default 15 s limits expired during the cold bake and the first Vite transform). Result: 59 of 62 assertions pass and the scenario fails. The three failures are the runtime budgets that PRD-585 already records as failing on this host: `afterFirstFrameTaskMs` up to 9 685 ms (limit 250), `timeToReadyMs` (limit 15 000) and `maxViewGpuMs` up to 62.09 ms (limit 12). The console, network and runtime-diagnostic policies pass. Captures of all five kits show textured bark, foliage, grass, rock and sand. AC-3 stays open until the preview passes as a whole. +- [x] AC-4 [local]: Each remaining hunk (depth cache, 3D guard, bind-group invalidation) has a spec that fails without it. proof: `three-patch-retained.spec.ts` on 2026-10-11 — depth cache red 1 failed/green 1 passed; 3D attachment guard red 1 failed/green 1 passed; bind-group invalidation red 1 failed/green 1 passed. Stock source hashes verified; requested suite passes 106/106. +- [x] AC-5 [local]: The `updateTexture` wrapper costs under 0.05 ms per frame on machinefall. proof: `TN_FRAME_SPANS` A/B, two runs per arm — Evidence (2026-10-11): the wrapper no longer exists, so it costs 0 ms per frame by construction and there is nothing left to A/B. `1b6b0f593` deleted it with the upload lane, because only that lane wrote `_pendingUploads` and `uploadError`. `three-compressed-upload.spec.ts` fails if `updateTextureAsync`, `_uploadTail`, `_pendingUploads` or `uploadError` reappear in the generated patches or the installed three build (106 of 106 core patch and upload specs pass at `c92f8c98a`). No `TN_FRAME_SPANS` run was made. + +## Execution Phases + +#### Phase 1: generated patches +**Status:** COMPLETE +**Files:** `packages/core/scripts/generate-three-patch.mjs` (new), `packages/core/package.json`, `.github/workflows/ci.yml` +- [x] Regeneration matches. proof: default `pnpm --filter @threenative/core patch:generate && git diff --exit-code packages/core/patches` passed after commit; a separate fresh build with `--check` printed `matched`.

No A/B run was needed. + +## Decisions + +- **2026-10-13 — scaffold fingerprints follow the geometry-cache patch.** Overlaying only the `adaeb514f` parent Three patch into thirteen generated scratch scaffolds reproduced all thirteen previous fingerprints without changing canonical source or installed dependencies; refreshed only the thirteen measured fingerprints for the current patch.

The lockfile delta is exactly 56 substitutions of the patch hash, with no other changes. Parent frozen install passed with the merged lock unchanged; the three focused patch specs passed 42 tests in 7.50 s, including all 31 legacy predecessors and all 30 previously shipped finals. A fresh default `pnpm --filter @threenative/core patch:generate --check` downloaded and built the pinned upstream and reported `matched`. CI structure/needs contracts passed 213 tests in 8.68 s. Actual CI, hand-edit rejection, upload migration, runtime/visual proof and wrapper cost remain open. + +Scaffold drift closure: the first parent pre-push gate passed 331 tests but rejected the stale thirteen-tree fingerprints. Restoring only the previous shared Three patch and capability manifest/reference bytes recovered every old fingerprint in the actual `createProject` test. The observed current fingerprints were then recorded, and the unchanged full-tree assertion passed for all thirteen templates (1 selected test, 67 unselected; 1.63 s). No template source or hash exclusion changed. + +2026-10-10 hand-edit rejection proof: parent copied the committed pin, source delta and patch artifacts to an ignored isolated directory, appended a hand-edited line to its base patch, and ran the real generator with `check: true`. A fresh pinned upstream download/build rejected the altered artifact with `check failed, generated patch drifts from the committed patch`. The checkout patch remained byte-identical. This closes the local negative case; AC-2 remains open for actual CI execution. + +2026-10-12 correction to the "patch still contains the upload-lane hunks" line under AC-3: the upload-lane hunks were removed in `1b6b0f593`, and the 3D guard and depth-cache hunks that remain are covered by `three-patch-retained.spec.ts`. Re-run today: `three-compressed-upload.spec.ts` (1 test) and `three-patch-retained.spec.ts` (3 tests) pass, 4 of 4. A token check of the committed patch finds none of the forbidden upload-lane tokens. AC-3 and the Phase 2 box stay unticked because their proof also names a WebGPU playtest of the preview, and the preview's web lane is currently red on the three PRD-585 perf budgets (the 59 of 62 passing assertions include no compressed-upload check that isolates this change). The uploader the PRD calls `texture-upload.ts` is `CompressedTextureUploads` at `packages/core/src/compressed-texture-preparation.ts`. + +2026-10-12 bounded-upload regression coverage: `pnpm exec vitest run packages/core/__tests__/three-compressed-upload.spec.ts` passes 3/3 after develop integration. The BC7 and non-square ASTC cases reconstruct every uploaded byte from bounded queue writes, verify the external texture replacement and backing-texture disposal, and retain the guard against the removed private Three upload lane. Scoped Biome passes. This mock-device check does not establish the outstanding full-preview or CI acceptance. + +2026-10-13 compressed completion observation: the existing prop preparation helper now reports distinct compressed originals actually replaced in material maps or TSL nodes after the renderer promise succeeds. JPEGs, identity/invalid replacements, unused map entries and failed uploads cannot increment the count; the numeric preparation return and ordinary progress callback retain their contract. GameState initializes, resets and publishes `compressedTexturesPrepared`. A direct regression fails before the callback/count change, then passes; parent direct and loading suites pass 36/36, example TypeScript and scoped Biome pass (eight complexity advisories). This is observation plumbing only. The current starter contains zero KTX2 textures, its twelve GLBs contain no KTX2/Basis images, and the current local-assets folder has no compressed textures or models. Therefore no impossible positive assertion was added to the default scenario. AC-3 and Phase 2 remain open pending a real compressed CC0 asset in an isolated preview run, without changing the immutable published starter archive or lowering existing runtime budgets. + +2026-10-13 isolated positive compressed-bark runtime attempt fails: the headed NVIDIA forest capture is blank and records17 console errors plus14 runtime diagnostic errors. The sealed UASTC archive/build and CPU quality measurements do not prove runtime acceptance. The first retained failure is WebGPU Device Lost (unknown: A valid external Instance reference no longer exists), followed by query/error-scope rejection. No preceding KTX upload/validation or network failure was captured. Preparation counter1 is observed, but no visible compressed rendering, visual acceptance or compressed native result is claimed; GPU-process exit code is unobserved. + +2026-10-13 positive compressed preview proof on the new geometry-cache candidate: two headed NVIDIA/Turing forest runs each pass10/10 assertions with zero console/network/runtime errors. Actual compressedTexturesPrepared is1 at player, meadow-close and overview in both runs; each pose is1920x1080 at scale1/MSAA4 with all four streaming queues zero. The frozen11175 game, UASTC bark and Basis bytes are unchanged; all30 installed Three final targets match the canonical cache fix. Parent fail-closed validators independently pass both runs. Fresh12-image review is NEUTRAL at every pose in both pairs: visible bark/foliage/terrain quality is retained, with no visible improvement or performance/device-loss causality claim. The earlier lost-device run remains failed. This supplies actual positive preview texture proof, but AC-3 remains open until the full preview passes its unchanged budgets; no new native compressed result is claimed. + +2026-10-14 CI qualification: the generated-patch step is now observed successful in the required build-artifacts job. The original local hand-edit rejection remains the negative control; no deliberately broken patch was pushed. This closes Phase 1 only. Strata runtime qualification fails in this run, so upload-lane and runtime acceptance stay open. diff --git a/docs/PRDs/strata-terrain-hardening/PRD-594-engine-changes-from-381-get-native-and-visual-proof.md b/docs/PRDs/strata-terrain-hardening/PRD-594-engine-changes-from-381-get-native-and-visual-proof.md new file mode 100644 index 0000000000..d6649e5fd5 --- /dev/null +++ b/docs/PRDs/strata-terrain-hardening/PRD-594-engine-changes-from-381-get-native-and-visual-proof.md @@ -0,0 +1,92 @@ +# PRD-594 — The engine changes that rode in with #381 get native and visual proof + +**Status:** PARTIAL +**Priority:** P1 — Six core behaviours from #381 that every game runs have no native conformance case and no visual-judge verdict (AC-1 to AC-6); "web-only is unfinished" applies. +**Complexity:** 5 (MEDIUM); risk override: supported-platform parity +**Owner:** ThreeNative maintainers +**Depends on:** None +**Epic:** [Strata terrain hardening](README.md) + +## Context + +Core audit of `2d2124792` (2026-10-10).

Source inspection identifies different moving-scene capture phases: browser waits26 rAF callbacks while native captures after300 host frames. The shared entry now prepares26 real moving render/history cycles, freezes the existing resolve and asserts both fixture and held frame26; it preserves native frame count and all tolerances.

Temporal fixture advances26 moving frames before holding the capture pose; still images do not prove motion stability. Atmosphere uses the shipped factory/forest parameters and exact old/current AtmosphereLuts under13 identical common inputs. All four atmosphere captures observe three compute submissions, two completed queue fences, null GPU validation, identical camera/sun/physical/tone/exposure and pixelRatio1 with antialiasing disabled. The initial diagnostic fixture failed before browser on empty registry exclusions; that failure is retained, and the corrected fixture uses all canonical exclusions with the existing full validator. Fresh read-only judgement is NEUTRAL per pair and overall, preserving shadow shading, temporal edges and sky/sun appearance.

Exact source/capture evidence, BASE develop `5f7143895`, artifact `11860557091`: the base `33-virtual-shadow` capture and the candidate first-frame capture have IDENTICAL metric `0.012477213541666667` and deltaE `0.0056963619722485` (sizes desktop `61538` / web `20307`), and the base `33-virtual-shadow` row passes at `pixelMismatchRatio` `0.08`; BASE has no first-frame case. Changed only the `virtual-shadow-first-frame` registry tolerance: `pixelMismatchRatio` `.01` → `.08`, `perceptualDeltaE` `3.0` unchanged, matching the `33-virtual-shadow` row. New red-first contract `tests/conformance-runner.test.mjs` — "a diagnostic row reusing a scene fixture keeps that scene's visual tolerance" — asserts the two rows share tolerance (RED at `.01`, GREEN at `.08`). The first-frame GPU-submission/completed-work/zero-error assertions stay strict: `tests/virtual-shadow-first-frame.test.mjs` and the scene comparator are unchanged. This is the harness/registry configuration layer, not engine rendering; no browser, GPU, native or full-CI execution was run.

No spec file changed. The world suite after a frozen install passed 40 of 41 files on the 4-core offload host. The 41st, `world-gpu-scene.spec.ts`, timed out one case at its 60 s limit there and on the loaded desktop (load 57), and it passed in full on the Debian laptop at the same commit.

It failed only `performance.minFps` (20.12, needs >= 25) and `maxFrameMsP95` (281.3 ms, needs <= 250). The develop control site failed the same bounds in both of its runs (19.26 and 23.92 fps, p95 223.1 and 404.1 ms). Host load was 48 to 56. The first candidate run had 4 failures from a one-off `ERR_NETWORK_CHANGED`. Functional walk: pass. Performance bounds: not proven on a loaded host. AC-3 stays open. + - Strata preview: the full `terrain.playtest.json` run on 2026-10-11 (PRD-593 lane, before this split) passed 59 of 62 assertions and failed the three PRD-585 runtime budgets.

The required red run failed all 1,000 seeds before the field existed because positive resident bytes could not be observed; after the minimal field addition every seed observes positive bytes and asserts zero bytes after draining. Independent focused gate passes in 2.31 s: 1,651 loads and actual geometries disposed exactly once, 417 pending disposals, 476 late completions, 1,428 evictions, 31 reentries, 357 seeds with positive HLOD bytes and all 1,000 with positive refcounts. Nearest unchanged `world-cells.spec.ts` and `world-cells-admission.spec.ts` pass 58 tests (14.01 s). Core typecheck passes after building this lane’s missing playtest dependency; no shared mutable dependency/build links were introduced. Scoped Biome passes with 22 existing/new nonfatal complexity warnings (one in the new scenario). The bounded Haiku arm timed out after saving its changes/logs; coordinator reviewed the diff and independently reran core typecheck and the fuzz gate. Parent review independently passes all 1,000 seeds (2.02 s), observing 1,650 loaded geometries disposed exactly once, 417 pending disposals, 476 late completions, 1,428 evictions, 31 reentries and 356 positive-HLOD seeds. Counts can vary with admission timing; each run retains the same seeded decisions and asserts every teardown invariant. No extraction, full-world suite or preview/machinefall proof is claimed; Phase 2 and AC-2/3 remain open. + +2026-10-11 Phase 2 first mechanical seam (PARTIAL): moved the queued model-load interface, `ModelLoadLimiter` and `AdmissionBudget` with their intact bodies/JSDoc to internal `world-load-limiter.ts`; dependencies are only type imports `Object3D` and existing `IAdmissionBudget` from `world-tiles.ts`. No public index export, behavior change, new dependency or test-file modification. Automated comparison confirms the moved block matches the committed original except class export keywords. Existing WorldCells/admission specs pass 58 tests (9.86 s); the unchanged 1,000-seed fuzz passes (2.03 s); core typecheck and scoped Biome pass (20 nonfatal warnings). The Haiku arm timed out at 600 seconds after saving the verified changes/logs; coordinator reviewed the diff and exact-body comparison. The module is 106 lines and `world-cells.ts` remains 10,230 lines, so the 3,000-line criterion is explicitly unfulfilled; other named seams, larger coherent class subsystems, the full unchanged world suite and preview/machinefall playtests remain open. + +2026-10-11 Phase 2 SharedBatch seam (PARTIAL): extracted `SharedBatch`, its owned caster/square types and packing scratch/helpers, and `PARKED_SHARED_CAPACITY` into internal `world-cell-batches.ts` (1,057 lines). Exact comparison confirms the original SharedBatch class body is unchanged apart from its export keyword. Internal exports are only `SharedBatch`, `sameSquares` and `ICasterScaleMesh`; dependencies are existing Three types/values, `InstancedBatch` (type-only), and mesh-pool functions, with no new context, public package API or runtime cycle. The architecture guard now names exactly the limiter and batch modules alongside world-cells and applies the identical prohibited constructor, appearance-property and hexadecimal-color regexes independently to all three; the global rule is unchanged. The prior genuine constraints baseline was red on `inFlight`; updated constraints pass all 4 tests. Unchanged WorldCells/admission specs pass 58 tests (18.52 s), the unchanged 1,000-seed race fuzz passes (5.11 s), core typecheck passes and scoped Biome passes with 23 nonfatal warnings. Existing world-* test files are unchanged. The bounded arm timed out after saving passing gate logs; coordinator reviewed the extraction and retained guard coverage. `world-cells.ts` remains 9,179 lines; Phase 2 and AC-2/3 remain open for further seams, coherent class subsystem extraction, full unchanged world tests and the preview/machinefall playtests. + +2026-10-11 Phase 2 bundle-safety seam (PARTIAL): moved 14 existing declarations (`PER_RENDER_UPDATE`, the graph/check interfaces, `BundleSurfaceSafety`, graph traversal/validation helpers and bundle eligibility functions) into internal `world-bundle-safety.ts` (295 lines), using only Three type imports and existing `isEngineRenderHook`; no runtime cycle, context abstraction or public package API was added. Independent TypeScript AST comparison confirms all 14 original bodies are unchanged except export keywords. The generic architecture rule actually matches the moved material-identity code, so the exact new filename is exempted and all three existing tighter appearance regexes apply unchanged to it alongside the other extracted modules. Existing world-spec files remain unchanged. The arm timed out after saving the extraction; its initial test/Biome commands had malformed arguments and did not prove those gates. Coordinator reran the corrected focused gate under the shared CPU lock/external 120-second limit: constraints, world-bundles, world-cells, world-cells-admission and the unchanged 1,000-seed race fuzz all pass (104 tests, 54.30 s). Core typecheck passes; corrected scoped Biome passes with 20 nonfatal warnings. `world-cells.ts` remains 8,889 lines, so Phase 2/AC-2/3 remain open for the remaining seams, cohesive class subsystems, full world suite and preview/machinefall playtests. + +2026-10-11 Phase 2 chunk-shadow seam (PARTIAL): moved the chunk-shadow helpers, `worldOwned` and three constants into internal `world-chunk-shadow.ts` (305 lines). Independent TypeScript AST comparison confirms all eight moved declaration bodies are unchanged except export keywords; headers/JSDoc are retained. `world-cells.ts` is 8,605 lines (8,889 before). The `bundleSafeMaterial` re-export is unchanged. Gates: core typecheck exit 0; scoped Biome exit 0 with 27 nonfatal warnings; `constraints.spec.ts` 4/4 pass; `world-cells-chunk-merge.spec.ts` 15/15 pass; `world-cells.spec.ts`, `world-cells-admission.spec.ts` and `world-cells-race.spec.ts` 59/59 pass, including the 1,000-seed race. The coordinator additionally ran unchanged shadow caster-cost and shadow-prewarm specs: 4/4 pass (2.56 s). The bounded Haiku arm timed out after saving its passing gate logs; the coordinator reviewed the diff and exact-body comparison. Existing world test files are unchanged. Other `world-*` files over 3,000 lines: `world-tiles.ts` 3,405 and `world-gpu-scene.ts` 3,243. Phase 2, AC-2 and AC-3 remain OPEN: four moves are still insufficient for 3,000 lines, and larger cohesive class subsystems, the full world suite and the preview and machinefall playtests are pending. + +2026-10-11 Phase 2 declaration seams (PARTIAL): extracted world-cell-data.ts (882 lines; 26 declarations including the verbatim existing IWorldCellsStats move, replacing untracked world-types.ts), world-tile-observation.ts (566 lines; 32 declarations including bridge topology validation and its constants), and world-gpu-validation.ts (517 lines; 30 declarations including shared matrix/indirect widths and reporting constants). TypeScript-AST token comparison, ignoring added export keywords only, passes all 88 moved declarations; all comments/JSDoc and retained declaration tokens are unchanged. Four tile helper functions use named exports to preserve their original parameter tokens under Biome. Dependencies on owner modules are type-only; no runtime owner import cycle was introduced. Original public re-exports are retained; index.ts, world.ts and every core spec remain unchanged. Remaining owner line counts: world-cells.ts 7,778, world-tiles.ts 2,880, world-gpu-scene.ts 2,774. Full unchanged world suite baseline: 40 files pass / 1 fails; 627 tests pass / 1 fails / 3 skip (84.57 s). After extraction: identical file/test counts (109.87 s); both failures are the same pre-existing 60-second timeout at world-gpu-scene.spec.ts:1156, so test retries/fixes stopped. Final core typecheck passes (exit 0); scoped Biome check --write passes (exit 0, 29 warnings); wc -l confirms both tiles and GPU scene are below 3,000 lines. No PRD boxes ticked. Phase 2 and AC-2/3 remain open: world-cells.ts is still over 3,000 lines, the baseline timeout is unresolved, and preview/machinefall playtests were not run under this declaration-only brief. No push. + +2026-10-11 Phase 2 CellPrewarm collaborator (PARTIAL): extracted 331 original lines across 24 private fields/methods, plus the four constants and their JSDoc, into internal world-cell-prewarm.ts (441 lines); WorldCells delegates through one instance and is now 7,438 lines. CellPrewarm owns its queue/key set, pending/mint/owed/drawn/epoch/wait and caster counters, awaited mesh hooks, settlement flag/resolver and promise. Its explicit 20-member ICellPrewarmHost is released, parent, invalidateShadows, backlog, keysForShadow, hasShared, hasRetired, runMax, residentCells, extentBounds, smallCaster, dressMesh, receiveShadow, adoptGpu, setShared, attach, casts, wideOwed, followCluster and wideShape; no owner instance or writable maps cross that interface. Reverse-boundary comparison of all 24 moved members, including comments and ignoring formatter whitespace, matches the original bodies. Hook restoration and queue settlement remain at their original disposal positions; mesh-visible casterPrewarmOwed is unchanged. Existing world specs and public entry-point exports are unchanged. Full unchanged world suite: 40 files pass / 1 fails; 627 tests pass / 1 fails / 3 skip (90.26 s), including the 1,000-seed race fuzz; the only failure is the documented pre-existing 60-second timeout at world-gpu-scene.spec.ts:1156. The first core typecheck caught the host smallCaster return declaration (number instead of boolean); after correcting that declaration, core typecheck passes (exit 0). Scoped Biome check --write passes (exit 0, 21 warnings); wc -l confirms world-cell-prewarm.ts 441, world-cells.ts 7,438, world-tiles.ts 2,880 and world-gpu-scene.ts 2,774. No boxes ticked; AC-2/3 remain open. No push. + +2026-10-11 Phase 2 CellChunks collaborator (PARTIAL): extracted 900 original lines across 37 members/declarations, plus the verbatim proxy eviction block, cellLoaded body and HLOD stats block, into internal world-cell-chunks.ts (1,050 lines); world-cells.ts is now 6,581 lines (7,438 before). CellChunks owns proxy states/materials, HLOD bytes/refusals/failures and cached renderer/camera as private fields; proxy cancellation delegates at its original eviction position. Nine explicitly typed immutable settings are copied once after their existing validation. Its 20-member ICellChunksHost is disposeProxyModel, disposeLoaded, releaseModelPaths, retainModelPaths, addFailures, sourceBytes, load, cellLive, add, intersectsObject, gpuSceneOn, asset, invalidateBundles, worldSphere, reportCellFailure, parent, prepareCompile, compileChunk, addChunk and publishChunkBounds. Source-model leases, bundle invalidation and ordered bounds publication use named operations; no owner instance or writable maps cross the boundary. The original async/then and liveness positions are retained. Reverse-boundary TypeScript token comparison passes all 37 moved members/declarations, the cellLoaded body and seven-line eviction block, normalizing trailing commas and formatter whitespace while preserving identifiers/operators/literals/control flow. Existing world specs, mesh-visible caster internals and public entry-point exports are unchanged. Initial wiring/import errors were corrected; an early suite started before those fixes was stopped. The first complete default-worker suite had 626 passing, two failing and three skipped tests: the documented GPU-scene 60-second timeout at world-gpu-scene.spec.ts:1156 and a 20-second timeout in the unchanged world-impostor-surface.spec.ts:254 TypeScript check under load 66.9. The full unchanged world suite rerun with --maxWorkers=1 passes 40 files / 627 tests, with three skipped and only the same documented GPU-scene timeout (312.70 s); the surface file passes all 13 tests in 10.70 s, chunk-merge passes all 15 and the unchanged 1,000-seed race fuzz passes in 3.74 s. Final core typecheck passes (exit 0); scoped Biome check --write passes (exit 0, 20 nonfatal warnings); wc -l confirms world-cell-chunks.ts 1,050, world-cells.ts 6,581, world-tiles.ts 2,880 and world-gpu-scene.ts 2,774. No boxes ticked. CellImpostors, CellModels, CellStreaming and CellRender remain unextracted; AC-2/3 remain open. No push. + +2026-10-11 Phase 2 CellImpostors collaborator (PARTIAL): moved 1,208 original lines across 40 method bodies, 22 private fields and 18 declarations into internal world-cell-impostors.ts (1,364 lines); world-cells.ts is now 5,434 lines (6,581 before). CellImpostors owns the baker, atlas cache/reservations, bake queue, far cohorts/segments/retries/cursor/temporary leases and wide retry set. Its 20-member ICellImpostorsHost is released, renderer, asset, hasAsset, assets, nearWorkPending, newAsset, startAssetLoad, release, noteGate, retargetWideCasters, terminalLevelReady, residentCell, canonical, shadowRecordsMoved, residency, add, remove, addFailure and markReleasedPart. Read-only settings and scratch transforms stay private; render-owned wide-caster handoff operations and ordered terminal-ready publication use explicit callbacks. No writable maps or owner instance cross the boundary, and the owner-module import is type-only. Reverse-boundary TypeScript token comparison, normalizing formatter whitespace/trailing commas, passes all 40 moved bodies, 22 fields, 18 declarations and 123 retained facade methods. Existing specs and public entry-point exports are unchanged. The first full world run on the overloaded desktop had 624 passed, four failed and three skipped (718.75 s): GPU-scene timeouts at 1156 and 1243, a later source-record mismatch, and the surface spec's explicit 20-second TypeScript timeout. The unchanged full rerun on the laptop checkout mirror with --maxWorkers=1 passes all 41 files / 628 tests, three skipped (190.46 s), including all 97 GPU-scene tests, all 13 surface tests and the 1,000-seed race fuzz. Final core typecheck passes (exit 0); scoped Biome check --write passes (exit 0, 15 nonfatal warnings); wc -l confirms all world-* modules except world-cells.ts remain below 3,000 lines. The extra constraints.spec.ts guard remains red (one failed / three passed): its generic filename allowlist already omits HEAD's world-cell-data/prewarm/chunks modules, and the new seam also needs coverage there; this brief prohibits editing specs. No boxes ticked; CellModels, CellStreaming and CellRender and AC-2/3 remain open. No push. + +2026-10-11 Phase 2 CellModels collaborator (PARTIAL): moved 884 original lines across 17 method bodies, nine private fields and 19 declarations/state initializers into internal world-cell-models.ts (1,029 lines); world-cells.ts is now 4,561 lines (5,434 before). CellModels owns loaded assets, loader ownership, the load limiter, model-path refcounts, shared surfaces and chain-LOD bookkeeping. The original module-global released-parts WeakSet is now private static state, retaining its cross-world identity/disposal semantics. Alias resolution remains a pure operation over the facade's immutable alias metadata; no writable map crosses the boundary. Its 16-member ICellModelsHost is canonical, noteGate, queueBuild, released, failures, setFailures, reportCellFailure, drainShared, residentCells, queuePrewarm, hasFarTemp, releaseFarTemp, maybeQueueImpostor, hasQueuedImpostor, cancelImpostor and releaseImpostor. Separate failure read/write callbacks retain the original read-before-teardown ordering of compound additions. Reverse-boundary TypeScript token comparison, normalizing formatter whitespace/trailing commas, passes all 17 moved bodies, nine fields, 18 ordinary declarations, 106 retained facade methods and the four original loader-construction statements; the released-parts initializer is unchanged. Existing specs and index.ts/world.ts exports are unchanged, and IAssetState remains re-exported through world-cells.ts. Initial export-modifier order and host stage-union errors were corrected; final core typecheck passes (exit 0), scoped Biome check --write passes (exit 0, 14 nonfatal warnings), and the unchanged full laptop world suite with --maxWorkers=1 passes all 41 files / 628 tests, three skipped (167.13 s), including the 1,000-seed fuzz, all 97 GPU-scene tests and all 13 surface tests. wc -l confirms every world-* module except world-cells.ts remains below 3,000 lines. The extra architecture guard identified in the previous collaborator is still unresolved and was not rerun; specs remain untouched. No boxes ticked and no push. + +The next CellStreaming seam was assessed without source edits: its 23 original methods (639 body/signature lines) currently touch 32 external operations/state reads before consolidation, beyond the brief's approximately 20-member host ceiling. The 19 existing collaborator accesses are models.acquire/asset/disposeLoaded/loadsInFlight/loadsQueued/release/releaseModelPaths; chunks.bytes/evictProxy/startChunkLoad; impostors.farBytes/farInstances/restoreFar/retryFar/rootsNeeded; prewarm.pending/queued; gpuScene.on; and terrain.deferredAdmissions. Nine facade operations are cullResident, swap, boundsAt, canonical, clearSegment, shadowRecordsMoved, changedBounds, dropChunkBundles and cullEvicted. Four lifecycle/counter accesses are released, shadowMoved and the failure counter's ordered read/write operations. They respectively preserve model leases and near/far admission, render publication/teardown, and liveness/failure accounting. Rather than widen the host or pass collaborator/owner bags, this round stops with that inventory for a smaller seam plan. CellStreaming and CellRender remain unextracted; AC-2 (world-cells.ts <=3,000) and AC-3/playtests remain open. + +2026-10-11 Phase 2 Part 1 architecture guard: constraints.spec.ts excludes exactly world-cell-data/prewarm/chunks/impostors/models.ts from its generic appearance-word scan and subjects all five to the existing tighter no-material/light/colour construction, no appearance-property reads and no colour-literal assertions. These are the previously documented verbatim WorldCells extractions; their material identity transport, load-flight names and numeric contracts were already allowed in world-cells.ts. No regex or directory pattern broadened. Red before: one failed / three passed; green after: four passed (567 ms). Scoped Biome passes (exit 0). Existing world-*.spec.ts files unchanged. No boxes ticked; no push. + +2026-10-11 Phase 2 Part 2 CellRender collaborator: extracted 58 existing method bodies and 17 declarations into internal world-cell-render.ts (2,463 lines); WorldCells now holds one CellRender and is 2,444 lines (4,561 before). CellRender owns shared/retired batches, bundle records and compile state, GPU scene/residency, culling squares, shadow regions and fresh-mesh allowance as private state. Its 20-member ICellRenderHost is asset, assets, canonical, renderer, camera, now, residentCells, runMax, widenFilterRange, addUnchanged, disableFar, deferWide, queuedBuilds, covered, prewarmSettled, awaitDraw, carryPrewarm, add, isParent and isBundleHome. Immutable construction settings are copied into private fields; attachment identity is answered by boolean operations, so no owner instance or writable map crosses the boundary. The tiny bundle-home identity method and streaming-owned source-rebuild orchestration remain in the facade. There is no runtime import of world-cells.ts, and public exports/spec-visible mesh internals are unchanged. The architecture guard names only the new render filename and applies the same existing appearance assertions. + +Part 2 verification: formatter-normalised TypeScript token comparison passes all 58 moved bodies, 53 original private field/settings/scratch declarations, 17 top-level declarations and 45 retained facade bodies, reversing only named collaborator-boundary substitutions. Separate comparisons pass the copied private bounds helper, compile/GPU blocks, full update/disposal ordering, bundle/main-cull stats snapshots and chunk-bounds publication. Initial typecheck caught stale facade wiring and the assets iterator declaration; the pre-bounds-restoration core typecheck passed (exit 0), but final typecheck FAILED: the restored facade bounds helper references IWorldAsset after import trimming removed that type import. The first final failure was masked by a following successful Biome command; the second typecheck exposed the same missing import. Per the brief, stopped edits and restored only the uncommitted Part 2 source changes to the already committed CellRender version. The committed extraction still needs that import restored; no final typecheck success is claimed. The first unchanged laptop world suite had 627 passed / one failed / three skipped: world-shadow-caster-cost.spec.ts:256 exposed the facade reading its bounds scratch while the moved helper wrote the collaborator's scratch. Restored the verbatim bounds helper beside each private scratch box; the focused shadow-caster-cost spec passes both tests. One full rerun was deferred before testing by the offload thermal guard (98 C); after cooling, the exact requested unchanged laptop suite passes all 41 files / 628 tests / three skipped in 67.58 s, including the 1,000-seed race fuzz. Final architecture guard: four passed. Scoped Biome: exit 0, 12 nonfatal warnings. Existing world-*.spec.ts, index.ts and world.ts remain unedited; no boxes ticked and no push. + +2026-10-11 Phase 2 Part 3 condition: world-cells.ts is already below 3,000 lines, so no CellStreaming extraction or remaining-seam proposal was started. All packages/core/src/world-* files are below 3,000 lines; the only files over 2,500 are world-tiles.ts (2,880) and world-gpu-scene.ts (2,774). Phase 2/AC-2/3 remain unticked as instructed; pnpm quality and preview/machinefall walk playtests were not run under this brief. + +2026-10-11 Phase 2 Part 2 stop rule: final scope review attempted to move seedGpuSources with three additional named host operations (takeBuildJobs, forgetQueued, queueBuild), for 23 members total. Token comparison passed 59 moved bodies and 44 retained facade bodies, but the repeated missing-IWorldAsset typecheck failure triggered the brief's rollback rule. Reverted those uncommitted source changes only; the committed version retains 20 host members and facade seedGpuSources, with the previously recorded 628 passed / three skipped world suite. No second full-suite run for the extra GPU-source move was started. Doubtful assumption: a successful combined shell command meant the earlier typecheck had passed; it did not. Remaining repair: restore the IWorldAsset type import, then reverify and finish the source-rebuild seam. No boxes ticked; no push. + +2026-10-13 isolated Machinefall candidate build: the owned test checkout installs packed core0.3.4 plus its matching playtest0.3.4 peer. The first resumed build publishes597 cooked outputs and527 manifest entries, then correctly fails bundling because old playtest0.3.3 lacks the new clock protocol exports; the matching peer fixes this without a gameplay edit. The subsequent normal build passes (Vite2.77s; terminal exit0 at16:49:33UTC). Parent audit verifies all597 receipt outputs with exact byte counts, all527 manifest main outputs, no pending journal, and all seven files referenced by dist/index.html. Installed core/playtest artifacts match the archives (core SHA256 `9a089679c0214a059fde63e12df242e8f2b8e2fa51a27167adbcdfbbf2e063d0`, playtest `9be97bf2f854578773e934cbe805ef153708bc2d6f27ba9b6788edc4598c4984`). Removed legacy Three patch registration is wholly superseded:30 installed target hashes match the canonical installer; its extra sample-count hash is redundant with context.sampleCount. Runtime map-walk and existing performance assertions remain unrun; phase2 stays open. + +2026-10-13 actual Machinefall map-walk: the unchanged scenario runs against the built candidate on NVIDIA Turing1280x720 for4383 frames. It passes19/20 assertions; diagnostics fails on789 GPU validation errors reusing destroyed RGBA32Float textures (2442x1 and4096x3,2 layers). Network/runtime diagnostic counts are zero. Streaming eviction/residency and bridge travel advance, ending with zero loads/failures, valid terrain spawn, zero air frames and zero grounding error. Existing performance rows pass their numerical checks, but the private display is insufficient for a real-display FPS claim. This is an actual failed consumer gate, not runtime acceptance; source ownership/lifetime tracing is underway without changing scenario limits. + +2026-10-13 lifetime diagnosis: actual GPU texture creation/destruction stacks identify terrain morph geometries replaced during WorldTiles edge synchronization. WorldTiles assigns the replacement before disposing the old geometry. An actual installed RenderObjects-method reproduction shows geometry replacement retains the old node builder/bindings and skips full cache-key validation, although the key already includes morph identity. The shared Three adapter fix adds geometry changes to that validation gate; the regression is RED on previous behavior. The meaningful regression is GREEN with the fix; 36 focused cache/pipeline/compatibility tests, core typecheck, Biome, build/publint and all30 installed target hashes pass.

The only conflict was the scaffold fingerprint table; all thirteen actual trees were measured, with only action-rpg changing. Scaffold and CI attempt-receipt specs pass 92/92. Laptop typecheck and lint pass after rebuilding core declarations. The real-display NVIDIA forest walk still fails its 16.7 ms gate (p95 98.7 ms, 71 timing samples); the follow-up trace diagnoses CPU and first-use compilation cost without claiming steady FPS. The standard V8 host, all V8 contract targets and the QuickJS cross-engine targets now build. Native package tests pass 1,586 with 62 skips; the six previously failing files pass 72 with one skip. A shared starter-archive fixture leaked its beforeAll directory; immediate try/finally cleanup fixes the monitored package-test guard (1 → 1 directories), with the full package-test phase exiting 0. The socket probe subsequently reproduced ECONNRESET from the test ClientRequest: the helper returned after its 413 response while a 10 MiB chunked upload remained in flight. Cancelling the remaining upload and waiting for request close passes twelve consecutive instrumented runs (216 assertions), without a reset or unhandled error. The final full unit phase passes 798 files and 10,636 tests, with 20 skips and temporary directories stable at 1 → 1. It ran with four available CPUs (three existing Vitest workers), avoiding the 60-second build-exit timeout seen under heavy unrestricted concurrency; no timeout or assertion changed.

Needle material and colour, cutout edges. + +A change that touches trees, ground, lighting or LOD ticks no box without an IMPROVEMENT verdict. The PRD 583 authored-noise ground attempt (REGRESSION) stays out of the tree. Perf wins count only after the judge passes. + +2026-10-14 upstream integration: at the owner's request, fetched and merged `origin/develop` at `99aeb6e30` (PRD-568 / #488, mobile GPU-ready ASTC textures) into this branch as `6db7012e4`. The sole conflict in `packages/assets/src/passes/lightmap.ts` preserves both this branch's asynchronous static bake and the upstream ASTC encoder argument. The focused lightmap/texture/model-texture/core-assets suites pass 198 tests with 1 skipped; assets and core typechecks and scoped Biome pass. Earlier terrain morph/LOD, cached shadow-page, first-frame GPU tier and height-fog work is already in the branch's ancestry. Fresh installed-consumer package freshness and full CI remain to be verified; source ancestry alone is not runtime proof. The owner also reports a close/far tree silhouette change and rejects lighting, shadows and atmosphere. Opus 5.5 high has reproduced a trunk LOD silhouette error substantially larger than the stored error and is implementing the repair; no visual or performance acceptance is claimed. diff --git a/docs/architecture/AGENT-INTERFACE.md b/docs/architecture/AGENT-INTERFACE.md index b96612da35..668e26f4e6 100644 --- a/docs/architecture/AGENT-INTERFACE.md +++ b/docs/architecture/AGENT-INTERFACE.md @@ -7,11 +7,13 @@ vocabulary. **What exists now that this file was written before.** The read-only half of the MCP layer this document argues for has shipped: [`threenative-engine-mcp`](../../packages/engine-mcp/) serves `engine_search_capabilities` and `engine_capability_detail` over the committed capability -manifest, and installing `@threenative/core` writes every project a `.mcp.json` wiring four +manifest, and installing `@threenative/core` writes every project a `.mcp.json` wiring five servers — `threenative-assets` (the externally pinned `threenative-asset-mcp`, launched through -a shim inside core), `threenative-sculpt`, `threenative-engine`, and `threenative-blender` +a shim inside core), `threenative-sculpt`, `threenative-engine`, `threenative-blender` ([`threenative-blender-mcp`](../../packages/blender-mcp/), which drives an installed Blender -headlessly so a downloaded `.fbx` becomes a GLB, and ships no Blender).

a skinned, multi-material or morph-target mesh, one carrying a baked AutoLOD chain, and an instanced mesh past `chunkMergeMaxTriangles` (default 43,690 triangles) or with a shape over 2,048 triangles, all keep their own geometry; a material group crossing 131,072 vertices (4 MiB of position + normal + uv) is split into several meshes in traversal order instead of one giant upload, indexed parts keep their index, and `TN_WORLD_CHUNK_MERGE` reports what the merge did and the bytes it left - * @constraint `shadows.castDistance` is accepted and ignored (clusters replaced it);

PORTABLE BY DESIGN

Take your terrain anywhere.

Keep the recipe. Bake the data your engine needs.

Preview and export resolutions are independent.
High-resolution bakes run in a separate worker.

Bring your own terrain

Project JSON, grayscale PNG8/16, or square RAW16 LE.
