+# CABR Consensus Finalization Phase 5 - Time Range and Receipt Correlation
+
+**Slice**: CABR_CONSENSUS_FINALIZATION_PHASE5_TIME_RANGE_RECEIPT_CORRELATION
+**Worker**: W1
+**Date**: 2026-05-13
+**Base**: 9ce780ae8 (after PR #582)
+
+## Overview
+
+This document audits the Phase 5 implementation of time-range query helpers and receipt correlation for the CABR consensus reporting layer. This builds on Phase 4 (aggregation/reporting) to enable filtered audits and cross-referencing consensus records to original CABR receipts.
+
+## WSP 97 Critical Constraint: Observability Only
+
+**CRITICAL**: Time-range queries and receipt correlation are read-only observability tools. They do NOT mean:
+
+| Prohibited Semantic | Implementation | Verdict |
+|---------------------|----------------|---------|
+| Automatic state progression | Read-only queries, no mutations | COMPLIANT |
+| `verification_complete=True` | Never set by any function | COMPLIANT |
+| `cabr_ready=True` | Never set by any function | COMPLIANT |
+| `payout_ready=True` | Never set by any function | COMPLIANT |
+| Payout approval | No payout logic | COMPLIANT |
+| DAO activation | No DAO transition logic | COMPLIANT |
+| External settlement | No network calls | COMPLIANT |
+| Default DB path | Caller must provide store explicitly | COMPLIANT |
+| Implicit filesystem writes | JSON export returns string only | COMPLIANT |
+
+## Scope Boundaries
+
+### In Scope
+- Time-range filtering for consensus record queries
+- Receipt correlation to trace consensus decisions back to source receipts
+- Correlation reports combining time filtering and receipt matching
+- Deterministic JSON export of correlation reports
+
+### Out of Scope (Prohibited)
+- Store mutation
+- Network calls
+- External attestation
+- Payout triggering
+- DAO activation
+- Token issuance
+- Default DB path
+- Implicit filesystem writes
+
+## API Design
+
+### Time Range Filter
+
+```python
+@dataclass
+class CABRTimeRangeFilter:
+    """Filter for time-bounded consensus record queries."""
+    start_time: Optional[datetime] = None
+    end_time: Optional[datetime] = None
+    limit: Optional[int] = None
+
+    def validate(self) -> bool:
+        """Return True if filter is valid (start <= end if both set)."""
+```
+
+### Time Range Query
+
+```python
+def query_consensus_records_by_time(
+    store: CABRConsensusStore,
+    time_filter: Optional[CABRTimeRangeFilter] = None
+) -> List[CABRConsensusRecord]:
+    """
+    Query consensus records with optional time-range filtering.
+
+    Returns records sorted by finalized_at descending (most recent first).
+    Raises ValueError if time_filter.validate() returns False.
+    """
+```
+
+### Receipt Correlation
+
+```python
+@dataclass
+class CABRReceiptCorrelation:
+    """Correlation between a consensus record and its source receipt."""
+    record_id: str
+    receipt_id: Optional[str]
+    matched: bool
+    decision: str
+    finalized_at: datetime
+
+def correlate_consensus_records_to_receipts(
+    records: List[CABRConsensusRecord],
+    receipts: Dict[str, Any]
+) -> List[CABRReceiptCorrelation]:
+    """Correlate consensus records to their source receipts."""
+```
+
+### Correlation Report
+
+```python
+@dataclass
+class CABRReceiptCorrelationReport:
+    """Report on receipt correlation with time filtering."""
+    time_filter: Optional[CABRTimeRangeFilter]
+    total_records: int
+    matched_records: int
+    unmatched_records: int
+    correlations: List[CABRReceiptCorrelation]
+    generated_at: datetime
+
+def generate_receipt_correlation_report(
+    store: CABRConsensusStore,
+    receipts: Dict[str, Any],
+    time_filter: Optional[CABRTimeRangeFilter] = None
+) -> CABRReceiptCorrelationReport:
+    """Generate a receipt correlation report with optional time filtering."""
+
+def export_receipt_correlation_report_json(
+    report: CABRReceiptCorrelationReport
+) -> str:
+    """Export receipt correlation report as JSON string (sorted keys)."""
+```
+
+## Test Coverage
+
+**File**: `test_cabr_phase5_time_range_correlation.py` (46 tests)
+
+| Category | Tests | Coverage |
+|----------|-------|----------|
+| Time filter validation | 7 | Valid/invalid ranges, edge cases |
+| Time-range queries | 8 | Start/end/both/limit, sorting, empty store |
+| Receipt correlation | 8 | Matched/unmatched/partial, empty inputs |
+| Correlation reports | 6 | Statistics, time filtering, accuracy |
+| JSON export | 7 | Deterministic output, datetime serialization |
+| Dataclass serialization | 4 | All dataclasses serialize correctly |
+| WSP 97 truth boundaries | 4 | All truth fields remain False |
+| Store requirements | 2 | Functions require explicit store |
+
+## Files Changed
+
+| File | Lines | Purpose |
+|------|-------|---------|
+| `src/cabr_consensus_reporting.py` | +~200 | Time-range and correlation functions |
+| `tests/test_cabr_phase5_time_range_correlation.py` | ~800 | Test coverage (46 tests) |
+
+## Implementation Notes
+
+1. **In-memory filtering**: Time filtering is done in-memory after fetching records from store (SQLite datetime comparison without schema changes)
+
+2. **String decision field**: `CABRReceiptCorrelation.decision` uses `str` type for consistency with existing reporting patterns
+
+3. **Deterministic JSON**: All JSON exports use sorted keys for reproducible output
+
+## Regression
+
+- All 199 existing CABR tests pass
+- 46 new Phase 5 tests pass
+- Total: 245 tests passing
+
+## Verdict
+
+**PHASE5_TIME_RANGE_RECEIPT_CORRELATION_COMPLETE**
+
+All WSP 97 truth fields remain False. No store mutations. No external calls. Observability only.
