- Around line 270-281: Update the audit details schema around the failure-case
result definitions to encode conditional status and match-cardinality
invariants: require covered results to contain only satisfied nested checks,
enforce consistent match arrays, and ensure deterministic tool_call results
include a tool and matching calls. Use the existing status, matches, and
toolCall schema symbols, preserving valid uncovered/violated result behavior.

Summary
Adds
failure_casesas a third audit coverage method, following the capability coverage behavior from #1570 while sharing their composite evidence engine. A failure case is covered only when all declared evidence is satisfied and no prohibited tool appears in the trace; subjective checks remain explicit, trace-bound skill judgments.Changes
--failure-case-judgmentssupport.prohibited_toolsis the only failure-specific deterministic gate, and trigger prose must be represented inevidence_requiredto affect coverage.Type of Change
