+# Local-Doc Runtime Roadmap Plan
+
+> Date: 2026-04-19
+> Parent Decision: `2026-04-19-residual-runtime-roadmap-prioritization-plan.md`
+> Parent Residual Bucket: `local_doc_pipeline`
+> Status: Draft
+
+## Plan Intent
+
+Plan the bounded closure path for the five `local_doc_pipeline` residuals selected by the residual runtime roadmap prioritization decision.
+
+## Fixed Input Bucket
+
+Only these scenes are in scope:
+
+1. `sweep-033-scene`
+2. `sweep-034-scene`
+3. `sweep-042-scene`
+4. `sweep-051-scene`
+5. `sweep-074-scene`
+
+## Initial Phases
+
+### Phase 0: Freeze Local-Doc Residual Baseline
+
+Capture current generation reports and missing pieces for the five scenes.
+
+### Phase 1: Local-Doc Evidence Inventory
+
+Classify document source, attachment dependency, local service dependency, and output artifact expectation.
+
+### Phase 2: Minimal Local-Doc Contract Design
+
+Define the smallest contract that can distinguish runnable local-doc pipelines from policy-held local-doc pipelines.
+
+### Phase 3: Bounded Implementation Slice
+
+Implement only the contract recovery or fail-closed detail required by the five-scene bucket.
+
+### Phase 4: Follow-Up Sweep And Reconciliation
+
+Rerun only the five target scenes and publish candidates. Do not update the official board inside this phase.
+
+## Forbidden Scope
+
+1. host-bridge runtime roadmap;
+2. bootstrap target normalization;
+3. G4/G5;
+4. full attachment runtime implementation unless explicitly required by the minimal contract;
+5. official board update.
+
+## Stop Statement
+
+Stop after the local-doc five-scene follow-up and reconciliation candidates are published. A later official board reconciliation plan must consume the result.
