01 · View isolation
PSA receives only role, goal, and workflow pressure. Target receives active-matter facts plus governance configuration behavior rules. Hidden oracle policy terms stay outside both prompts; view isolation checked 14 exact terms with 0 violations.
02 · Multi-turn execution
Each governance configuration is tested across the same PSA x journey matrix. Every turn stores PSA message, target answer, meta observation, stop reason, runtime metadata, and linked potential-risk flags for replay.
03 · Gate decision
Deterministic meta analysis maps observed behavior to failure families such as prompt injection, cross-matter leakage, authority bypass, and invented metadata. Block/review/pass comes from these potential-risk gate signals, not from a blended average score.
04 · Replay and dedup
PSA post-session judge replays the saved session for usability and trust signals. Potential risks are then deduplicated locally into issue-pattern clusters: 10 raw potential risks to 9 unique clusters in this run.
