Polish v0.40 world fidelity and runtime coherence

[NellInc]

Summary

1. Refines the unified factory world with a nearby instanced city, corrected tarmac response, restrained night lighting, a road-projected truck headlight shader, and checkpoint clearance dwell with live signals.
2. Makes truck, trailer, forklift, wheel, steering, articulation, and checkpoint motion measurable at display cadence.
3. Repairs tour camera ownership and cancellation while preserving collision protection for manual WASD and Q/E navigation.
4. Unifies production and SCADA reporting around deterministic, authoritative values.
5. Corrects benchmark budgets and evidence for one percent lows, p95, p99, frame spikes, DPR, world continuity, uncrewed state, motion, and checkpoints.
6. Filters the current public build so immutable v0.10, v0.20, and v0.30 payloads are not duplicated into v0.40 output. v0.40 remains the default and version number stays locked.
7. Contains no humans, personnel models, voices, personnel modules, or human assets.

Root causes addressed

The manual collision solver intercepted authored camera flights. Production cards derived a second synthetic throughput story. SCADA noise used random values. Checkpoint arms reacted without a trailer clearance dwell. Translucent headlight cones became faceted geometry at night. Vite copied all historical releases before deleting the duplicates. Runtime evidence lacked staccato motion, tail latency, and checkpoint gates.

Validation

1. VERSION=v0.40 npm run build: passed, 3,592 modules.
2. npm run typecheck, npm run lint, formatting, and git diff --check: passed.
3. Vitest: 105 files and 1,031 tests passed.
4. Depth, shader, asset, bundle, uncrewed, and release matrix validators: passed.
5. npx impeccable detect src: passed with no findings.
6. Strict native five view runtime benchmark at commit 807f84d: all views passed. Average FPS ranged from 83.1 to 119.3, one percent low from 56.5 to 79.8, p95 from 9.5 to 13.3 ms, p99 from 10.2 to 14.6 ms, effective DPR 1.20, valid motion, valid checkpoints, continuous world, and no humans.
7. Fast 3G startup: all five views passed at 3,072.3 to 3,080.5 ms against the 3,200 ms budget.
8. Browser interaction pass: tour movement and skip passed, WASD and Q/E passed, focused controls blocked camera translation, and no page errors occurred.

Review notes

The genuine historical releases remain immutable. The protected working checkout and its two unrelated untracked files were not modified. Performance numbers are reported as candidate health, not as an improvement claim without a hash-matched earlier baseline.
