Updated PR head c258bd5 and redeployed it to westendli.dev via successful workflow run https://github.com/paritytech/dotli-community/actions/runs/34138758069. The App v2 runtime now requires ABI 2, so I migrated and republished Chinpokomon 0.1.12 (runtime ABI 2) at CID bafybeia26pviq4ffm263mlrdlaiggtvnpbu4xdqualud5p2xb5hqzrhny4. Fresh-profile live verification at https://chinpokomon-pvm.westendli.dev/ resolved through smoldot/Bitswap without the cold-start No connected peers failure, mounted the PolkaVM JIT canvas with data-polkavm-ready=true, and advanced from frame 2178 to 2298 over 2 seconds at ~57 FPS. |

Reverts f24d3dc. ABI 1 was never released, so a breaking change is spent inside it rather than on a version no product has shipped against. ADR 0001 records the decision and the migration this Host would need before any move to 2.
Reverts f286e61. @useragent-kit/polkavm-runtime 0.6.28 packages polkavm-host-runtime cc9940b6 and declares abi.runtime 2; the App contract this Host implements is ABI 1, published from polkavm-host-runtime itself, and 0.1.15 also carries the safe-area and virtual-keyboard inset ABI that 0.6.28 predates.

Repin the Host to the useragent-kit distribution of host-runtime 0.2.0 at a9156ad. Consume its canonical polkavm-prefixed artifact names directly, retain exact package checksums, publish ABI 1 provenance, and pick up inset input plus bounded WebGPU device restoration.

Scope correction: the computer contract has been removed from #185 and rebuilt as draft stacked PR #215. #185 now remains limited to the runtime-aware App work tracked by host-rust-core #507/#540/#550. Although GitHub records this PR as merged, its squash commit is no longer reachable from the rewritten #185 head; #215 is the authoritative computer stack and must remain unmerged pending the host-interface RFC. |
