@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?

Revended reviewed host-rust-core commit 56c67a306fc276129829f94db85a622061e17882. Re-ran the canonical matrix on this exact vendor: Doom, Quake, Duke3D, NES, egui kitchen sink, GPU Cube, and Scene Lab all passed through Dotli's compiler backend.

CI diagnosis: the red E2E job is not specific to this branch.

• main has the same host-playground product-account failures in runs 33158665346 and 33112105412.
• I reran this PR's failed jobs as attempt 2 of 33206120102; pairing and product loading succeeded, then accounts-provider-product remained pending and the dependent TrUAPI cases cascaded.
• Unit, Functional, bundle, lint, and the independent seven-app PolkaVM browser matrix pass.

No Dotli source change is justified for this shared signer/product-account path; the check needs the external E2E dependency restored or the repository's existing external-outage policy applied.

westendli.dev deployment 33225654653 completed successfully for f1c2e68, but live verification is blocked by stale environment infrastructure:

• westendli.dev and wildcard subdomains resolve to 151.115.144.84.
• Ports 80 and 443 on that address are unreachable.
• The other staging domains resolve to the current shared staging host 51.159.177.252.
• The repository Makefile declares every non-production environment, including dev-westend, on the shared staging box.

Repair requires provisioning the westendli.dev, *.westendli.dev, and *.app.westendli.dev nginx/certificate configuration on the current staging host and updating the Cloudflare DNS records. The build artifacts are already deployed; no Duke republish is needed.

Live PVM acceptance on westendli.dev — the missing proof

The earlier note on this PR was that the E2E product suite skipped (Nova signing bot unavailable), so live DotLi PolkaVM acceptance stayed unproven. It is proven now, against the deployed westendli.dev host, for two independently published products.

Deploy run 33775043152 from this branch's head shipped all three builds — host 8.3 MB, sandbox 1.2 MB (contains /pvm-runtime/), protocol — and the runtime assets serve:

Resolution chain, end to end

Host resolved the DotNS label, threaded the CID through the URL contract, and mounted the sandbox with the v=4 executable-manifest contract (the older failure was v=3 without it):

• responsive-egui00.paseo → bafybeiawkfp3wps7azyww6omgfjphxuwu3w7do2aafy2xtylno45gwyfqi
• responsive-egui.paseo → bafybeidldnath3lzdste4h3b5rqckvorsmkuvmejnfr4wmzkga77tz5kte

Both on network=paseo-next-v2, profile=tri2d, pointer + keyboard in requiredFeatures.

Runtime metrics

Steady state measured by frame delta, not the reported counter: 304 frames in 5 s = 60.8 fps. Translation 176–187 ms.

Responsive contract holds under resize

Three breakpoints against the live host, no runtime restart, pvmReady stayed true across all resizes:

Vertex count shifts per breakpoint, so the guest genuinely re-lays-out rather than scaling one fixed scene. Medium's 2096 matches the Epoca figure exactly — same artifact, two independent hosts.

Local suites on the rebased head: 27/27 sandbox, 2/2 PVM functional (1 skipped, needs CAR fixture paths).

This PR is MERGEABLE with all checks green and remains blocked only on REVIEW_REQUIRED, since I pushed the rebase and cannot self-approve.

Updated to host-rust-core #540 head 85effb1b05cdfefa1e48ba3b2da4fb58684cd780 and pvm-host-runtime v0.1.8 at 530885a9d6dbf5a2742d4f2ff9f5c71b05f2a762. All required checks, functional coverage, E2E, and westendli.dev deployment are green. Normal merge is blocked only by the required review policy; auto-merge is disabled for this repository. Ready for maintainer approval.
