09 — D1/D2 Expansion Work (Workstream H)

Content work that proceeds with no runner and no endpoint — done this run, not just planned. No source IU/document edited. Two new companion docs published.

Published

1. knowledge/dev/design/knowledge-graph/d1-supp-kg-explain-pilot-and-discovery-status-2026-06-04.md — companion to D1. Adds: the 36-DOT/18-pair correction (live count 36 members; "18 orphaned producers" was a fixed filter bug); the EXPLAIN pilot subgraph as the canonical KG dry-run shape; the fixture-soundness proof (self-check 7/7 + negative control); the IU 10649925 bridge connection; live process-discovery status.
2. knowledge/dev/sop/dot-kg/d2-supp-endpoint-dryrun-ladder-2026-06-04.md — companion to D2. Adds: the full plan_only_tested → endpoint → dry_run_observed → real_run_observed → verified ladder with dot:kg's exact rung; the precise endpoint blocker; safe (no-execution) inspection commands; carried + new runbook warnings; the verifier re-classification note.

Why companions, not edits

D1/D2 are DRAFT/CANDIDATE law-adjacent docs. Per safety, the original information_unit/knowledge_documents source content is not edited. These are new derived docs that reference and extend D1/D2.

Coverage vs the prior readiness plan (doc 11 of prior macro)

• KG cluster refinement (pilot subgraph, dry-run shape) ✅
• dot-kg SOP ladder + endpoint sequence ✅
• 36-DOT correction + IU 10649925 connection ✅
• runbook warnings (dispatcher cannot execute, DRY_RUN refused, auto-approve trigger, births, RO timeout, 0 executions) ✅
• family diagram: described textually in D1-supp §1–2 (engine mix + pilot); a rendered diagram is a follow-on.

Completion

The content side advanced even though the runtime endpoint remains blocked.
