Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures.
Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments.

Contract
- assert spawn executes a child process and zod validates command arguments and environment configuration
- assert spawn stdout json output parses and passes zod schema validation
- assert spawn exit code and signal status adhere to process completion zod schema
- assert spawn non-existent command triggers error event validated by zod node error schema
- assert spawn with piped stdin processes stream and zod validates transformed output
