From 7a2ccfef9789272c09c7fac24f21162336238bc4 Mon Sep 17 00:00:00 2001 From: lysrain21 Date: Tue, 22 Sep 2026 03:29:59 +0000 Subject: [PATCH 1/6] Add an independent Go runtime for the XIR execution layer go-runtime/ implements the delivery, confirmation, and recovery paths of the XIR runtime independently of the Python campaign machinery: - internal/xir, internal/abiutil: byte-exact wire encoding and ABI packing. - internal/state, internal/evm: durable SQLite ledger, JSON-RPC client, signer, and a transactor whose intent/frozen-calldata/signed/submitted sequence survives a restart without rebroadcasting or reusing a nonce. - internal/artifacts, internal/deploy: Forge artifact loading, the Hyperlane and LayerZero stack bootstrap, the XIR application deployment, and the registry/adapter configuration. - internal/layerzero, internal/hyperlane: packet/checkpoint codecs and the DVN/Executor and validator/relayer roles the local lab needs. - internal/runner: attempt loop, carriers, transitions, delivery, effect checks, and an injected-fault hook for recovery tests. - internal/lab: disposable anvil chains for integration tests. - cmd/xirlab-go: CLI; keys come from environment variables only. - scripts/generate_go_parity_vectors.py and testdata/vectors.json pin every derivation against the Python reference. Verification: go vet and go test are green across the module, including an anvil integration test that deploys both protocol stacks plus one XIR application on three chains, executes an HL route end to end, and a recovery test that injects a fault after the first dispatch and resumes from the same ledger with the dispatch count unchanged. Planning, governance gates, analysis, and publication remain Python-side; a Go run is not a campaign result. --- .github/workflows/ci.yml | 25 + CLAIM_BOUNDARIES.md | 16 + README.md | 10 +-
