Required scenarios covered

• Base root → child → leaf (1, 2, 11). DOT category drill (2). Topic candidate → IU substrate (3, 4, multiple IUs).
• AX-PROCESS job:cut → 8 step-kinds (5); owner-blocked candidate (6, 11-member, BLOCKED_OWNER).
• AX-TRIGGER class → trigger rows (7); process-relevant cron (8).
• Process×Trigger gap → actionability ledger (9, 10).
• count>1 but no grouping rule → NEEDS_GROUPING, NOT fake drill (12) — the anti-fake-drill rule proven.

Failure classification (none triggered)

All 12 PASS. The matrix is a live view — re-running it re-computes verdicts from current PG state.
