07 — D1/D2 KG / dot-kg Expansion (Workstream F)

Content work that proceeds with no deployed endpoint. Two new companion docs published this run (read-back verified). No source IU/document edited.

Published this run

1. knowledge/dev/design/knowledge-graph/d1-supp2-endpoint-feasibility-and-verifier-fix-2026-06-04.md — D1 companion. Adds: EXPLAIN pilot is buildable on existing infra (OpenAI credential + egress); the fixture as the canonical KG dry-run shape; the verifier-correctness lesson (a verifier that cannot fail is not a verifier); the 36-DOT/18-pair correction; the job:cut contrast; operational lesson.
2. knowledge/dev/sop/dot-kg/d2-supp2-endpoint-service-deploy-ladder-2026-06-04.md — D2 companion. Adds: concrete endpoint service requirements; the 7-rung deploy+dry-run ladder; policy gates; runbook warning badges (incl. the verifier fix); the future true-dry-run command.

Builds on prior companions

Extends d1-supp-... and d2-supp-... from the prior macro. Together the D1/D2 companion set now covers: pilot subgraph + dry-run shape, endpoint blocker → feasibility, the full ladder, the policy gates, the verifier correctness lesson, and the warning badges.

Why companions, not edits

D1/D2 are DRAFT/CANDIDATE law-adjacent docs; original information_unit/knowledge_documents content is not edited (safety). These are derived docs that reference and extend D1/D2.

Read-back

Both documents created (revision 1) and confirmed present via the KB.

Completion

Content side advanced materially even though the runtime endpoint is not yet deployed — and now carries the corrected feasibility story and the verifier lesson.
