IU A–F Automated Evidence & Demo Pack — Overview & Verdict

Mission: IU_A_TO_F_AUTOMATED_EVIDENCE_AND_USER_VISIBLE_DEMO_PACK Date: 2026-05-29 · Host: contabo VPS · Container: postgres · DB: directus (PostgreSQL 16.13) Read channel: MCP query_pg as role context_pack_readonly (READ ONLY, AST-validated, 5 s timeout). Apply channel (D/E only): ssh contabo "docker exec -i postgres psql -U workflow_admin -d directus -v ON_ERROR_STOP=1" < file.sql, all mutation wrapped in BEGIN … ROLLBACK.

Purpose

Technical, evidence-backed proof — for independent GPT review — that the Information Unit (IU) is a real, production-pilot-ready "smart brick": stable with PostgreSQL, the DOT command layer, the queue/event substrate, SQL links, and the three reconstruction/filter axes. This is not UI work; every claim below is reproducible from a function call + raw query.

Verdict table

Cap	Capability	Method	Channel	Verdict
A	Cut → pieces → reconstruct (ordering + hash)	fn_iu_reconstruct_source + content-hash chain	read-only	PASS (reconstruct); cut-automation gap documented
B	Domain / specialty axis filter	fn_iu_filter_axis_b (DOT dot_iu_filter_axis_b)	read-only	PASS
C	Parent→child→grandchild subtree filter	fn_iu_filter_axis_c_subtree / fn_iu_subtree (DOT dot_iu_subtree)	read-only	PASS
D	Compose / add / remove / reorder / split / merge / render	fn_iu_compose + collection ops + fn_iu_piece_split + fn_iu_piece_merge	governed BEGIN..ROLLBACK	PASS
E	Trigger out / in + DLQ replay	fn_iu_emit_event + fn_iu_route_worker_run + fn_iu_route_dead_letter_replay	governed BEGIN..ROLLBACK	PASS
F	SQL link validate / resolve	fn_iu_sql_link_resolve_all (DOT dot_iu_sql_link_resolve)	read-only	PASS

Overall: PASS. All six capabilities have command + input + output + raw evidence + verdict. B/C/F run entirely through shipped DOT/wrappers; D/E run the governed safe path (gated, rolled back). A proves automatic deterministic reconstruction and states the exact cut-automation gap.

Hard Gate 0 (all 10 checks PASS)

1. Host = contabo VPS ✓ 2. Container = postgres ✓ 3. DB = directus ✓
2. Read identity = context_pack_readonly ✓ 5. Apply identity = workflow_admin (SELECT confirmed) ✓
3. fn_iu_gate_verify_closed(NULL) → all_safe=true, never_flip_intact=true, all_governed_closed=true (10 gates) ✓
4. idle in transaction = 0 (both roles) ✓ 8. Baseline snapshot captured (below) ✓
5. Server-side timeouts used (statement_timeout, idle_in_transaction_session_timeout set LOCAL in every apply tx) ✓
6. No client-timeout-kill of any open transaction ✓

Safety summary

• Zero persisted mutation. Exit counts equal entry counts; demo_rows=0, gate_transitions=0.
• Gate posture unchanged: all_safe / never_flip_intact / all_governed_closed = true.
• Never-flip keys (iu_enact.allow_no_review_decision, iu_core.vector_sync_enabled) untouched and false.
• No real route delivery (delivery_enabled=false, delivery_live_routes=""); 0 sent attempts from the demo.
• No 4-Mothers runtime, no Nuxt/UI, no Directus mutation, no Qdrant/vector, no job execution.
• No idle-in-transaction residue left behind.
