## 3. Findings Register & Human Review Log

### 1. [CALC-001] Net electricity export mismatch
- **Severity**: `CRITICAL`
- **Status**: `OPEN`
- **Detail**: The net electricity exported in the monitoring report (152,345 MWh) does not match the sum of monthly meter readings (149,120 MWh).
- **Remediation**: Reconcile the report total with the monthly meter log and correct whichever figure is wrong.
- **Cited Document Evidence**:
  > "Extracted source evidence matching rule CALC-001"

### 2. [DATE-004] Gap in meter data coverage
- **Severity**: `CRITICAL`
- **Status**: `RESOLVED`
- **Detail**: No readings were found for 14 to 19 March 2023. Monitoring periods must be covered without gaps.
- **Remediation**: Attach the missing readings or document the outage with supporting evidence.
- **Cited Document Evidence**:
  > "Extracted source evidence matching rule DATE-004"
- **Review Justification**: *Plant maintenance log and grid operator outage memo attached. Verified zero generation during maintenance window.*

### 3. [DOC-002] Calibration certificate expired
- **Severity**: `CRITICAL`
- **Status**: `ACKNOWLEDGED`
- **Detail**: The meter calibration certificate expired on 30 September 2023, before the end of the monitoring period.
- **Remediation**: Provide a valid certificate covering the full period.
- **Cited Document Evidence**:
  > "Extracted source evidence matching rule DOC-002"

### 4. [UNIT-003] Unit inconsistency in emission factor
- **Severity**: `MATERIAL`
- **Status**: `OPEN`
- **Detail**: The grid emission factor is reported as 0.82 t/MWh in one table and 820 kg/MWh in another. Values agree once converted.
- **Remediation**: Use one unit across the report and state the conversion.
- **Cited Document Evidence**:
  > "Extracted source evidence matching rule UNIT-003"

### 5. [CONS-007] Installed capacity differs between documents
- **Severity**: `MATERIAL`
- **Status**: `OPEN`
- **Detail**: The monitoring report states 100 MW, the PPA states 98.5 MW.
- **Remediation**: Confirm the as-built capacity and align both documents.
- **Cited Document Evidence**:
  > "Extracted source evidence matching rule CONS-007"

### 6. [DOC-009] Stakeholder consultation record undated
- **Severity**: `MATERIAL`
- **Status**: `RESOLVED`
- **Detail**: The consultation record does not show a date, so it cannot be tied to the monitoring period.
- **Remediation**: Add the consultation date and signatory.
- **Cited Document Evidence**:
  > "Extracted source evidence matching rule DOC-009"
- **Review Justification**: *Reconciled with utility meter records.*

### 7. [PLAU-002] Capacity factor above plausible range
- **Severity**: `MATERIAL`
- **Status**: `OPEN`
- **Detail**: The implied capacity factor is higher than the configured upper bound for this project type. Confirm the generation figure.
- **Remediation**: Check generation data for double counting.
- **Cited Document Evidence**:
  > "Extracted source evidence matching rule PLAU-002"

### 8. [DOC-011] Report version not recorded
- **Severity**: `MATERIAL`
- **Status**: `OPEN`
- **Detail**: The monitoring report has no version number or issue date on its cover page.
- **Remediation**: Add document control details.
- **Cited Document Evidence**:
  > "Extracted source evidence matching rule DOC-011"

### 9. [FMT-001] Inconsistent date format
- **Severity**: `MINOR`
- **Status**: `OPEN`
- **Detail**: Dates appear as DD/MM/YYYY and YYYY-MM-DD in the same report.
- **Remediation**: Standardize to one format.
- **Cited Document Evidence**:
  > "Extracted source evidence matching rule FMT-001"

### 10. [FMT-004] Missing figure caption
- **Severity**: `MINOR`
- **Status**: `OPEN`
- **Detail**: Figure 3 has no caption or source note.
- **Remediation**: Add a caption with the data source.
- **Cited Document Evidence**:
  > "Extracted source evidence matching rule FMT-004"
