+# Timeout Rerun Hygiene Integration Plan
+
+> Date: 2026-04-19
+> Status: Draft
+> Upstream Design: `docs/superpowers/specs/2026-04-19-timeout-rerun-hygiene-integration-design.md`
+> Upstream Hygiene: `tests/fixtures/generated_scene/timeout_budget_rerun_hygiene_2026-04-19.json`
+
+## Plan Intent
+
+Integrate timeout rerun hygiene into sweep and reconciliation reporting.
+
+This plan only changes the reporting layer. It does not change scene generation behavior.
+
+## Scope Guardrails
+
+1. do not modify `src/generated_scene/analyzer.rs`
+2. do not modify `src/generated_scene/generator.rs`
+3. do not update `scene_execution_board_2026-04-18.json`
+4. do not promote scenes
+5. do not rerun the `102` sweep
+6. do not start timeout implementation fixes
+
+## Fixed Inputs
+
+1. `tests/fixtures/generated_scene/structured_fail_closed_improvement_followup_2026-04-19.json`
+2. `tests/fixtures/generated_scene/timeout_budget_rerun_hygiene_2026-04-19.json`
+
+## Phase 0: Freeze Inputs
+
+### Objective
+
+Freeze the sweep follow-up and timeout hygiene inputs.
+
+### Tasks
+
+1. verify follow-up sweep status counts
+2. verify timeout hygiene summary:
+   - `rerun-resolved-pass = 2`
+   - `rerun-resolved-fail-closed = 1`
+   - `rerun-still-timeout = 0`
+   - `rerun-error = 0`
+
+### Deliverables
+
+1. frozen integration input set
+
+### Acceptance Criteria
+
+1. only the fixed follow-up and hygiene inputs are used
+
+## Phase 1: Build Hygiene Overlay
+
+### Objective
+
+Attach timeout hygiene results onto raw timeout scenes.
+
+### Tasks
+
+1. match timeout hygiene records to the follow-up sweep by `sceneId`
+2. preserve raw `source-unreadable`
+3. add:
+   - `hygieneStatus`
+   - `hygieneInterpretation`
+4. map:
+   - `rerun-resolved-pass -> timeout-as-pass-candidate`
+   - `rerun-resolved-fail-closed -> timeout-as-fail-closed-candidate`
+   - `rerun-still-timeout -> timeout-still-unreadable`
+   - `rerun-error -> timeout-rerun-error`
+
+### Deliverables
+
+1. timeout hygiene overlay records
+
+### Acceptance Criteria
+
+1. all three timeout scenes receive one overlay status
+2. raw status is preserved
+
+## Phase 2: Build Integrated Summary
+
+### Objective
+
+Publish a hygiene-aware timeout summary alongside the raw sweep summary.
+
+### Tasks
+
+1. preserve raw follow-up status counts
+2. add hygiene-aware timeout interpretation counts
+3. summarize:
+   - `timeout-as-pass-candidate`
+   - `timeout-as-fail-closed-candidate`
+   - `timeout-still-unreadable`
+   - `timeout-rerun-error`
+
+### Deliverables
+
+1. integrated summary block
+
+### Acceptance Criteria
+
+1. raw and hygiene-aware summaries both exist
+2. timeout bucket is no longer lossy in the integrated output
+
+## Phase 3: Publish Integrated Output
+
+### Objective
+
+Publish the bounded reconciliation-friendly hygiene integration output.
+
+### Tasks
+
+1. write `tests/fixtures/generated_scene/timeout_rerun_hygiene_integration_2026-04-19.json`
+2. write `docs/superpowers/reports/2026-04-19-timeout-rerun-hygiene-integration-report.md`
+3. state that this is an interpretation/reporting layer only
+
+### Deliverables
+
+1. timeout hygiene integration JSON
+2. timeout hygiene integration report
+
+### Acceptance Criteria
+
+1. both files exist
+2. no execution board update is made
+3. no implementation change is made
+
+## Completion Criteria
+
+This plan is complete when:
+
+1. inputs are frozen
+2. timeout hygiene overlay is attached
+3. integrated raw and hygiene-aware summaries are published
+4. JSON and report are written
+
+## Stop Statement
+
+Stop after publishing the integration JSON and report.
+
+Do not start implementation or board updates inside this plan.
