Module bundle 

Evidence bundle schema.

Each causal/effect verification produces an EvidenceBundle that captures the full methodological chain from question through estimation and refutation.

Required Fields (per canonical spec)

• causal question
• unit definition
• treatment specification
• outcome specification
• covariates/confounders recorded
• identification rationale
• estimator and estimate
• refutations attempted + results
• raw receipt / trace / replay handles
