Group	Cases	Verdict
Original v1 cases (carried forward verbatim)	12	PASS
Grouped PXT nodes (live from grouping surface)	10	PASS
Empty-substrate candidates (live)	2	PASS_WITH_EXPECTED_BLOCKER
Authority-blocked exemplars (PROC:official_rp, PROC:jobcut_verified)	2	PASS_WITH_EXPECTED_BLOCKER
Total	26	22 PASS / 4 EXPECTED_BLOCKER / 0 FAIL

Verdict semantics (no fake-green)

• PASS — drill capability proven end-to-end (Layer 1 → drill while count>1 → substrate). Grouped PXT nodes pass because DRILL_GROUPS now reaches real children then substrate; owner blockers remain in warning_flags as status.
• PASS_WITH_EXPECTED_BLOCKER — UI correctly renders the node, but the object is blocked by authority (no president vote / owner) or empty-by-design. The UI behaviour is correct; the blocker is real and shown, not hidden.
• FAIL — none.

Representative new cases

• V2-GRP-TRIG:db_dml_trigger — count 408 → DRILL_GROUPS into 177 groups → SHOW_SUBSTRATE. PASS. warning: BLOCKED_OWNER (review-only infra), LARGE_GROUP.
• V2-GRP-PROC:new_candidates — 6 candidate groups (50 members). PASS.
• V2-EMPTY-WPC-UNCLASSIFIED — count 0, SHOW_EMPTY_BANNER, EXPECTED_EMPTY_EVIDENCE_GATED_CATCHALL, NOT_A_JOIN_BUG. EXPECTED_BLOCKER.
• V2-BLK-PROC:official_rp — BLOCKED_NO_PRESIDENT_VOTE shown as status. EXPECTED_BLOCKER.
