// extrage-artefact.mjs: the compiled AereComputeMarketV3 as ONE file beside this component, taken from the hardhat build-info of the
// contracts project (roadmap point 28, 2026-10-02): abi, creation and runtime bytecode, the immutable references WITH their names (so a
// reader can rebuild the exact runtime code of a deployment from its constructor arguments and compare it with eth_getCode), the
// compiler and its settings, and the SHA-256 of the Solidity source the build-info holds (checked equal to the source in the tree).
// Deterministic: the same build-info gives the same file. Refuses a build-info whose source differs from the tree.
//   node extrage-artefact.mjs            writes AereComputeMarketV3.json
