03 — D1 Knowledge Graph Cluster Document (Workstream B)

D1 is published as a standalone KB design document (so it is discoverable outside this report):

➡️ knowledge/dev/design/knowledge-graph/d1-knowledge-graph-curated-cluster-2026-06-04.md — D1 — Knowledge Graph: Curated Cluster (Điều 39 consolidated), DRAFT/CANDIDATE.

Why standalone

A curated cluster document belongs in the KG design space, not buried in a report directory. It is referenced here for completeness of the macro deliverable set.

D1 section index (what it contains)

1. Purpose · 2. Scope · 3. Source IUs (the 16) · 4. Vision & 5-tier value chain (#0) · 5. Definitions & trust survival gate (#2) · 6. The 26 problems & group C architecture (#1, #5) · 7. Execution environment & 14 PG config tables + stack/sync (#7c, #8) · 8. The 10 processes A–J & the 36 DOTs — the bridge (#6-10, #7-36) · 9. Governance & the golden rule (#7b, Đ37) · 10. Relation to Registries-Pivot · 11. Current gaps · 12. Next actions · 13. Evidence references.

Status & safety

• DRAFT/CANDIDATE — curation of enacted text, not law; promotes nothing.
• No IU body edited; no taxonomy node; no promotion. Authored from live evidence 2026-06-04.
• Companion operational document: D2 (knowledge/dev/sop/dot-kg/d2-dot-kg-process-family-sop-runbook-2026-06-04.md).

Key content moved into D1 (not repeated here)

• The trust survival gate + trust_score = confidence × freshness_decay × provenance_weight × source_authority.
• The full process A–J ↔ 18 producer/verifier DOT-pair table.
• The golden rule TBox/ABox boundary and the unregistered-KG-owner governance blocker.
• The Registries-Pivot relation and the orphaned-producer caveat (detail in doc 04).
