Test WASM Modules

These are minimal WASM modules used for testing runtime overhead.

add.wasm

• Size: 41 bytes
• SHA256: f61fd62f57c41269c3c23f360eeaf1090b1db9c38651106674d48bc65dba88ba
• Exports: add(i32, i32) -> i32
• Description: Simple addition function for basic runtime testing
• Source: Hand-crafted binary (equivalent to WAT: (module (func $add (param i32 i32) (result i32) (i32.add (local.get 0) (local.get 1))) (export "add" (func $add))))

wasi_hello.wasm

• Size: 38 bytes
• SHA256: 53bd3da2fb75bcafb0677938f211ce6c85da8b6c1b6607b239786373b767e155
• Exports: hello() -> i32
• Description: Minimal WASI module that returns 42
• Source: Hand-crafted binary (returns constant value, no actual WASI imports)

extism_echo.wasm

• Note: Requires Extism PDK to build. Will be created when needed for Extism-specific tests.
