+# Promotion And Board Reconciliation Policy Plan
+
+> Date: 2026-04-19
+> Status: Draft
+> Parent Framework Plan: `docs/superpowers/plans/2026-04-19-scene-skill-102-full-coverage-framework-plan.md`
+> Parent Route: `Route 6: promotion and board reconciliation`
+> Parent Layer: `Layer E`
+> Upstream Design: `docs/superpowers/specs/2026-04-19-promotion-and-board-reconciliation-policy-design.md`
+
+## Plan Intent
+
+Publish the promotion and reconciliation policy that governs how future stronger statuses may update official scene-state assets.
+
+## Fixed Input Bucket
+
+Policy inputs only:
+
+1. `auto-pass`
+2. `fail-closed-known`
+3. `adjudicated-valid-host-bridge`
+4. hygiene-aware timeout interpretation
+
+## Allowed Files
+
+1. policy design and plan docs
+2. policy JSON assets
+3. policy reports
+
+## Forbidden Files
+
+1. `src/generated_scene/analyzer.rs`
+2. `src/generated_scene/generator.rs`
+3. `tests/fixtures/generated_scene/scene_execution_board_2026-04-18.json`
+
+## Tasks
+
+1. define promotion thresholds
+2. define how timeout hygiene is represented
+3. define how structured fail-closed progress is represented
+4. define what evidence is sufficient for board reconciliation
+5. publish policy assets
+
+## Expected Coverage Delta
+
+No direct scene-count delta is required.
+
+The expected result is policy readiness for later rule-driven reconciliation.
+
+## Completion Criteria
+
+1. promotion thresholds are explicit
+2. timeout hygiene representation is explicit
+3. board update rules are explicit
+
+## Stop Statement
+
+Stop after the Route 6 policy is published.
+
+Do not update the execution board under this plan.
