Treat missing, partial, unknown, and unresolved call coverage as insufficient for call-set equality. Combine IDA caller/callee coverage without losing either explanation and recheck source coverage when verifying historical comparisons.
Scope generated function-comparison unknowns with optional typed comparison/dimension facts, preserving legacy IDs and revision digests when absent. Keep unrelated dimensions conclusive, explicit dependencies applicable, and ambiguous function identity unknown. A confirmed change for matched functions remains a failure even if calls are incomplete.
Validation: function/reconstruction/residual-unknown and bundle tests, recorded IDA protocol regression, public MCP comparison/verification, and advertised SDK JSON Schema checks. Real IDA provider execution was not verified.
Fixes#2222
Reject omitted segment bounds, procedure classification and body facts, unresolved-call observations, dossier facets, and Ghidra parameter flow metadata. Providers emit explicit nulls for unsupported facets. Verify those unknowns in the real Hopper workflow.
BREAKING CHANGE: Provider analysis outputs must explicitly supply metadata previously repaired with defaults; unsupported nullable facets must be reported as null.
