+# Final 2 Residual Roadmap Prioritization Report
+
+> Date: 2026-04-19
+> Plan: `2026-04-19-final-2-residual-roadmap-prioritization-plan.md`
+> Parent sequence: `2026-04-19-final-2-residual-child-plan-sequence-plan.md`
+
+## Scope
+
+This decision consumed the current official board state after local-doc reconciliation refresh. Only two framework structured fail-closed residuals remain:
+
+| Scene id | Scene name | Current archetype | Next action |
+| --- | --- | --- | --- |
+| `sweep-085-scene` | `计量资产库存统计` | `host_bridge_workflow` | `future-host-bridge-runtime-roadmap-input` |
+| `sweep-091-scene` | `配网异常设备监控统计` | `page_state_eval` | `future-bootstrap-target-normalization-roadmap-input` |
+
+No code was changed, and the official board was not updated by this plan.
+
+## Decision
+
+Selected first roadmap:
+
+`bootstrap target normalization roadmap`
+
+Selected plan:
+
+`2026-04-19-bootstrap-target-normalization-roadmap-plan.md`
+
+## Rationale
+
+Bootstrap target normalization is the narrower next step:
+
+1. It is a single-scene residual.
+2. It targets deterministic bootstrap target recovery or a narrower named hold.
+3. It avoids host-runtime transport semantics.
+4. It has lower regression risk against already passing host-bridge paths.
+
+Host-bridge runtime remains queued:
+
+`2026-04-19-host-bridge-runtime-roadmap-plan.md`
+
+## Output Asset

+
+## Closure
+
+This prioritization plan is complete. The next executable plan is:
