What

  • load signed PolkaVM App v2 archives in the sandbox.
  • run framebuffer, Tri2D, and WebGPU profiles through the host runtime bridge.
  • consume truapi-pvm-host@e892cd9d and standalone runtime v0.1.5@81a484a1 through the reviewed bridge.
  • synchronize and verify browser assets from the bridge exporter with one source-bound lock.
  • route baseline TrUAPI request/response frames between PVM workers and Dotli’s canonical product MessagePort.
  • refresh translated/interpreter WebGPU capabilities after resize so stale surface generations recover.
  • resolve optional motion input as unavailable when a browser host has no active sensor source; pointer input remains the fallback.
  • keep the runtime namespace outside product-controlled service-worker routes.
  • add configurable seven-app smoke coverage.

Verification

  • sandbox tests: 21 passed, including canonical MessagePort negotiation.
  • sandbox lint and TypeScript checks: passed.
  • production sandbox build: passed with bridge-owned runtime 0.1.5 assets.
  • bridge asset synchronization and checksum gate: passed.
  • focused PVM functional suite: passed.
  • App Kit pvm-truapi-playground CAR: compiler/Tri2D rendering passed and canonical TrUAPI handshake request/response counters both advanced.
  • Chinpokomon App v2: compiler/WebGPU rendering, window resize, and subsequent input passed.
  • canonical seven-app Dotli compiler matrix: passed.

@justraman the PVM change is green across formatting, build, unit, functional, and the canonical seven-app Dotli matrix. The broad host-playground E2E remains red on the same account, allowance, and navigation failures as current main (the latest main Tests runs also fail); it does not exercise this PVM path. Could you review the runtime adapter so this can follow host-rust-core#540?

Warm-cache reload is now fixed in 1a8aa4d839bdf6f5a74a125eae24578d8f043914.

Root causes:

  1. performance Playwright reused any process already listening on port 5173, so local runs could silently test a stale build;
  2. a same-iframe reload posted a second truapi-ready, but the Host had removed its probe listener after the first handshake and the original MessagePort could not be transferred again;
  3. runtime readiness did not wait for the translated-byte IndexedDB write to settle.

Changes:

  • isolated performance server via PERF_PORT and reuseExistingServer: false;
  • retain the modern Host handshake listener and replace the product-side provider with a fresh MessageChannel on every subsequent truapi-ready;
  • wait for the bounded translation-cache write before exposing runtime readiness;
  • behavioral unit coverage for the second port handoff.

Verification on an isolated current branch build:

  • live doom.paseo manifest resolution: passed;
  • live Quake translated runtime: passed;
  • live Duke bounded hostcall/audio runtime: passed;
  • live Doom cold compiler/playability and warm same-iframe cache hit: passed;
  • full live PVM performance file: 4/4 passed;
  • UI tests: 217 passed;
  • sandbox tests: 17 passed.

⚠️ E2E Product suite skipped — Nova signing bot is unavailable.

This is a Nova-side outage and not a dot.li test failure. Re-run
