GAP-L2-P2-coverage-checklist-internal-broken-refs

Current state

Beyond PathDescriptor (its own gap), coverage-checklist mentions:

• OntologySchema — used in row "Catalog / Ontology" but not in v6 nodeKinds (it IS in repo schema, line 23-30)
• Mux (as schema element) — coverage-checklist treats ExtensionInterface kind=mux as the mapping, but no kind attribute is declared on ExtensionInterface
• ProcessLibrary — referenced row 406 ("modeled as ProcessLibrary") but no such NodeKind in v6 ontology-schema.yaml; only ProcessDescriptor
• SharedContextSpec — coverage row 139 ("structured Claim attached to ... as a SharedContextSpec") — no such named claim shape
• RunJournalEvent — row 154 ("enum RunJournalEvent") — but enums in v6 are not first-class schema elements
• DecisionVerb — row 104 ("ordered enum DecisionVerb") — same issue

Desired state

Either (a) add the missing NodeKinds and named-enum primitives to schema, or (b) downgrade those coverage rows to 🟡 (partial) with a remediation plan in place. Currently they are marked ✅ falsely.

Evidence

• C:/work/v6/graph/coverage-checklist.md (rows 139, 154, 104, 406, 524)
• C:/work/v6/graph/schema/ontology-schema.yaml

Propagation status

• Level 2: open

Propagation chain

• Level 2: choose for each row: promote-to-schema or demote-status.

Notes

Self-audit gap. The coverage-checklist's gate criterion ("Every row in the coverage table has Status... no row left blank") is being met only because rows are over-claiming ✅.
