03 — Empty Substrate Closure (Track B)

The 2 unresolved substrate nodes are AX-PROCESS process candidates with member_count=0. Inspected against wf_process_candidate — neither is a join bug; both are empty-by-design.

Node	classification	ai_review_state	next_action	empty_reason	verdict
WPC-MONITOR-BOOTSTRAP	COMPONENT_OF_EXISTING_PROCESS	AI_REVIEWED_PASS	ATTACH_AS_COMPONENT	EXPECTED_EMPTY_COMPONENT_BUCKET	PASS_WITH_EXPECTED_BLOCKER
WPC-UNCLASSIFIED	NEEDS_MORE_EVIDENCE	NEEDS_MORE_EVIDENCE	REQUEST_MORE_EVIDENCE	EXPECTED_EMPTY_EVIDENCE_GATED_CATCHALL	PASS_WITH_EXPECTED_BLOCKER

Reasoning

• WPC-MONITOR-BOOTSTRAP — notes: "ensure-*-kuma-monitor, ensure-qdrant-backup-cron = bootstrap components". This is a component bucket, not a standalone leaf process; its would-be members were re-classified as components of existing processes → 0 members is correct. UI: render empty-by-design banner, no substrate expected.
• WPC-UNCLASSIFIED — notes: "catch-all; evidence insufficient to cluster". Empty because nothing currently clusters in. UI: evidence-gated banner.

Decision

Read-only classification only. No deletion — both are canonical, owner-gated wf_process_candidate rows. v_rp_empty_substrate_classification exposes the reason + UI treatment; proof matrix v2 marks them PASS_WITH_EXPECTED_BLOCKER.

Result

missing_substrate unexplained 2 → 0 (2 classified, 0 bugs).
