description	Run Z3 verification for Mumei .mm source using mumei verify --json or the validate_logic MCP tool, then interpret proof status and counterexamples.

Given Mumei .mm source, prove every atom contract with Z3 and return a structured pass/fail result. Prefer the MCP validate_logic tool when available; otherwise use the CLI.

Step 1: Prepare the .mm source

Action: Locate the target .mm file or write the provided source to a temporary .mm file. Confirm it contains atoms with requires, ensures, optional effects, and valid module imports.

Expectation: Source is syntactically ready for mumei verify.

Result: If the source is ready, proceed to Step 2. If dependencies or imports are missing, report them before verification.

Step 2: Run verification

Action: Run Z3 verification with machine-readable output.

Expectation: The CLI prints a JSON report, or the MCP tool returns a verification section with JSON and semantic feedback.

Result: Verification succeeds when every proof obligation is discharged. Continue to Step 3 to interpret.

mumei verify input.mm --json

With cargo from the compiler checkout:

LLVM_SYS_170_PREFIX=/usr/lib/llvm-17 cargo run -- verify input.mm --json

MCP equivalent:

validate_logic(source_code)

Step 3: Interpret the result

Action: Parse semantic_feedback, machine_readable, failure_type, actions, and counter_example.

Expectation: On success, report all constraints satisfied. On failure, identify the atom, violated obligation, and concrete counterexample values when present.

Result: If verification passed, downstream skills may run: build or certify. If verification failed, run diagnose.
