+# Timeout Rerun Hygiene Integration Design
+
+> Date: 2026-04-19
+> Status: Draft
+> Upstream Hygiene: `tests/fixtures/generated_scene/timeout_budget_rerun_hygiene_2026-04-19.json`
+> Upstream Reconciliation: `tests/fixtures/generated_scene/full_sweep_status_reconciliation_2026-04-19.json`
+
+## Intent
+
+Integrate timeout rerun hygiene into future sweep interpretation and reconciliation reporting so budget-sensitive timeout scenes are not miscounted as a single `source-unreadable` bucket.
+
+This is a reporting and classification integration only. It does not change analyzer or generator behavior.
+
+## Problem Statement
+
+The timeout hygiene layer now distinguishes:
+
+1. `rerun-resolved-pass`
+2. `rerun-resolved-fail-closed`
+3. `rerun-still-timeout`
+4. `rerun-error`
+
+Without integration, a future sweep or reconciliation still risks reporting:
+
+`source-unreadable = 3`
+
+when the actual hygiene-aware interpretation is:
+
+1. `2` budget-sensitive pass candidates
+2. `1` budget-sensitive fail-closed candidate
+3. `0` persistent timeout after rerun
+
+## Scope
+
+In scope:
+
+1. define a hygiene-aware reporting schema
+2. define how raw timeout status and rerun hygiene status coexist
+3. define reconciliation-layer summary fields
+4. define output JSON and report for the integrated view
+
+Out of scope:
+
+1. analyzer changes
+2. generator changes
+3. execution board updates
+4. scene promotion
+5. full `102` sweep rerun
+6. timeout implementation fixes
+
+## Integration Rules
+
+### Raw Status Preservation
+
+The raw sweep status is preserved.
+
+Example:
+
+`source-unreadable`
+
+remains stored as the raw sweep result.
+
+### Hygiene Overlay
+
+When a timeout record has a hygiene record, the integrated layer adds:
+
+1. `hygieneStatus`
+2. `hygieneInterpretation`
+
+### Hygiene Interpretation
+
+Allowed integrated timeout interpretations:
+
+1. `timeout-as-pass-candidate`
+2. `timeout-as-fail-closed-candidate`
+3. `timeout-still-unreadable`
+4. `timeout-rerun-error`
+
+### Summary Output
+
+The integrated summary must report both:
+
+1. raw status counts
+2. hygiene-aware timeout interpretation counts
+
+This prevents lossy reporting.
+
+## Output
+
+1. `tests/fixtures/generated_scene/timeout_rerun_hygiene_integration_2026-04-19.json`
+2. `docs/superpowers/reports/2026-04-19-timeout-rerun-hygiene-integration-report.md`
+
+## Success Criteria
+
+1. raw timeout counts remain visible
+2. hygiene-aware timeout interpretation counts are added
+3. the three timeout records become distinguishable in reconciliation reporting
+4. no analyzer or generator code is changed
+5. no execution board state is updated
