+# G3 Residual Contract Closure Report
+
+> Date: 2026-04-19
+> Parent Plan: `docs/superpowers/plans/2026-04-19-g3-residual-contract-closure-plan.md`
+> Parent Route: `Route 2: G3 / paginated_enrichment`
+
+## Scope
+
+This report closes the final Route 2 residual-contract child plan.
+
+The plan only covers residual `G3 / paginated_enrichment` records after:
+
+1. `G3 enrichment-request closure`
+2. `G3 export-plan closure`
+
+## Inputs
+
+Input assets:
+
+1. `tests/fixtures/generated_scene/g3_enrichment_request_closure_followup_2026-04-19.json`
+2. `tests/fixtures/generated_scene/g3_export_plan_closure_followup_2026-04-19.json`
+
+## Residual Inventory
+
+Post child-plan residual count:
+
+1. after enrichment-request closure: `1` residual handed to export-plan closure
+2. after export-plan closure: `0`
+3. residual before this plan: `0`
+4. residual after this plan: `0`
+
+## Implementation Decision
+
+No implementation slice was needed under this residual plan.
+
+Reason:
+
+1. the enrichment-request subgroup was resolved or handed off
+2. the export-plan subgroup was resolved
+3. no named residual `G3` blockers remained for this plan
+
+## Route 2 Status
+
+`Route 2: G3 / paginated_enrichment` is now considered `completed` for the current child-plan sequence.
+
+## Handoff
+
+Next route:
+
+`Route 3: G2 / multi_mode_request`
+
+Next plan:
+
+`docs/superpowers/plans/2026-04-19-g2-remaining-fail-closed-closure-plan.md`
+
+## Stop Statement
+
+This report closes the Route 2 residual-contract plan.
+
+Do not begin Route 3 work under this plan.
