07 — IU Pilot Day 1 Read-Only Rehearsal (Branch G) — PASS

Executed live this session via context_pack_readonly (read-only). No mutation, no pilot evidence rows created (zero-mutation session choice; optional control-row pack in §7). All checks match the durable baseline.

1. b/c/f wrappers — operational

• Axis B fn_iu_filter_axis_b('legal_domain:knowledge_systems',5): iu_count=16, axis_b_consistency.consistent=true (normalized=16, denormalized=16), source distribution coherent (doc:DIEU-39 / file both 16). ✅
• Axis C fn_iu_filter_axis_c_subtree('cb211ee6-…',100): node_count=8, parent_outside_subtree=0, integrity: self_parent_cycle=0, orphan_dangling_parent=0, root_with_nonzero_depth=0, self_in_ancestors_cycle=0. Caveat (expected): depth0_with_parent_stale=23 / stored_depth_parent_mismatch=23 — stored axis_c_depth stale because three_axis_auto_refresh is OFF; fn_iu_subtree relative_depth is authoritative. ✅
• Axis F fn_iu_sql_link_resolve_all(): 3 links, resolved_true=3, all_view_eq_direct=true, all enabled=false (protected). Objects: v_iu_section_type_vocab_sync (view), fn_iu_three_axis_envelope_refresh (function), tac_publication (table) — all pg_class/pg_proc match. ✅

2. d/e/f protected status — confirmed closed

fn_iu_gate_verify_closed(): all 10 gates is_safe=true; composer/structure_ops/operator_runtime/delivery/three_axis_auto_refresh/emit/dlq.replay/job_substrate = false (governable); vector_sync + allow_no_review_decision = false (never_flip intact). ✅

3. Gate state — all_safe

all_safe=true, never_flip_intact=true, all_governed_closed=true (checked 05:33Z and re-confirmed via cockpit 05:33Z). ✅

4. fn_phase0_cockpit — baseline

meta169/coll168/tbl21/gov9/evt40/cat53/run55; KG iu_relation 60 (enriched provenance 60, confidence 60); factories 4 draft; mother_events 9 total / 0 active; phase0_blockers G1–G4 all human-pending; candidate_registry all unborn. ✅

5. KG audit — fn_iu_kg_edge_audit()

total_edges=2259 (universal 2199 + iu_relation 60). by_edge_type: USES 1486 / BELONGS_TO 431 / CONTAINS 342. iu_relation: provenance_filled 60/60, assertion_filled 60/60, evidence_filled 0 (deliberate). universal_edges provenance_filled 0 (deliberate — integer-keyed, excludes IU). ✅ No quarantine condition.

6. DLQ + routes — expected state

• iu_outbound_route: 15 total, 15 enabled, 15 dry_run=true (safe posture: enabled-but-dry).
• iu_route_attempt: 68.
• v_iu_route_dead_letter_open: 0. job_dead_letter: 0.
• iu_sql_event_route: 1, enabled=0. ✅

7. Evidence path + closeout

• Evidence path: all read-only outputs above ARE the Day-1 evidence; archive this doc as the Day-1 record.
• Optional control rows (NOT created this session): if the operator wants persisted pilot evidence, a single pilot_evidence/control draft row may be inserted in a BEGIN..ROLLBACK-proven, owner-clear table — deferred here to keep the session zero-mutation.
• Closeout template (Day 1):
  • gate all_safe=true · [ ] cockpit baseline unchanged · [ ] b/c/f wrappers green (16/8/3) · [ ] KG 2259, 60/60 enriched · [ ] DLQ 0/0 · [ ] routes 15 dry_run · [ ] no idle-in-tx at close · [ ] stop conditions not triggered.

8. Verdict

IU Pilot Day 1 read-only rehearsal: PASS. System is in the correct limited-pilot posture; Day 1 is runnable now with zero risk. No stop condition triggered.
