Walkthrough
The board runner now executes Wasm 1.0 core modules alongside components. Firmware validates core-module imports and memory, embeds module bytes, and selects the interpreter at runtime. Build workflows and tests include core-module scenarios.
Changes: Board core-module support
Layer / File(s)
Summary
Core-module detection and configurable execution services/ws-wasi-runner/src/core_module/*, services/ws-wasi-runner/tests/core_module.rs
The runner detects Wasm 1.0 core-module headers and supports configurable memory allocators and stack sizes. Tests check core-module detection.
Board hosting and memory-budget integration services/ws-wasi-runner/src/board/*, services/ws-wasi-runner/README.md, services/ws-wasi-runner/tests/board.rs
The board runner hosts core-module imports through BoardHost and accounts for linear memory through CoreMemory. Tests exercise core-module execution, host operations, memory limits, and supervision.
Core-module validation and guest generation libs/core-guest/src/abi.rs, services/firmware-modules/*
Firmware guest generation validates core-module imports and memory, embeds core modules without precompiling them, and checks aggregate memory use. Tests cover accepted modules and refusal cases.
Firmware runtime and build integration .github/workflows/no-std.yaml, .mise/config.rust.toml, CHANGELOG.md, services/ws-server-firmware/*
The firmware uses the runner’s guest supervision and supports interpreter execution for core modules alongside components. Build configuration and workflows include a core-math1 scenario.
