S137A Backfill Report — Architecture v3.0 Phase 4

Session: S137A | Date: 2026-03-19 | Status: COMPLETE

Assembly Gate

Cau 0: YES — PG functions + INSERT data only.

lifecycle_log Backfill (Rule 8: 730 -> 0)

Created fn_backfill_lifecycle_log() — dynamic from meta_catalog. 827 rows inserted across 19 managed collections. Rule 8 Liveness violations: 730 -> 0.

universal_edges Backfill (Rule 4: 730 -> 563)

Created fn_backfill_universal_edges() — 3 edge sources:

1. Directus FK relations: 8 relationships -> 324 edges (BELONGS_TO + CONTAINS pairs)
2. entity_labels: 27 USES edges (entity -> taxonomy label)
3. taxonomy self-refs: 21 BELONGS_TO edges (parent_id)
4. Taxonomy -> taxonomy_facets: 78 edges (not available via managed-only FK)

Total: 450 edges created.

Remaining 563 Rule 4 violations: standalone entities with no FK relationships (dot_tools=111, collection_registry=105, trigger_registry=84, etc.). This is expected — Rule 4 is warning severity.

Engine Results Post-Backfill
