# OCR Truth Audit Report - 23T2B8ZX
- Mode: `high-risk`
- Status: `READY`
- Reviewed pages: [1, 2, 3, 4, 5, 6]
- Reviewed blocks: 117
## Findings
- `critical` `reference_span_error`: block appears inside the logical reference reading-order region

- `critical` `reference_span_error`: block appears inside the logical reference reading-order region
- `major` `same_page_boundary_error`: page contains mixed body/reference/tail signals
- `minor` `render_mapping_error`: some render-default blocks are not easily mapped into the current fulltext output
## Disposition Guidance
- Use `repair` when the finding reflects a pipeline defect worth fixing now.
- Use `residual` when the finding is real but intentionally deferred.
- Do not rewrite expected truth to make current output look correct.

# OCR Truth Audit Report - 24YKLTHQ
- Mode: `high-risk`
- Status: `READY`
- Reviewed pages: [1, 3, 4, 5, 6, 7, 8, 10]
- Reviewed blocks: 114
## Findings
- `critical` `reference_span_error`: block appears inside the logical reference reading-order region
- `critical` `reference_span_error`: block appears inside the logical reference reading-order region

- `critical` `reference_span_error`: block appears inside the logical reference reading-order region
- `critical` `reference_span_error`: block appears inside the logical reference reading-order region
- `major` `frontmatter_error`: frontmatter page retains elevated unknown_structural density
- `major` `same_page_boundary_error`: page contains mixed body/reference/tail signals
- `major` `object_ownership_error`: ambiguous or unresolved object ownership remains in the current artifact set
- `minor` `render_mapping_error`: some render-default blocks are not easily mapped into the current fulltext output
## Disposition Guidance
- Use `repair` when the finding reflects a pipeline defect worth fixing now.
- Use `residual` when the finding is real but intentionally deferred.
- Do not rewrite expected truth to make current output look correct.

# OCR Truth Audit Report - 27MSS3VH
- Mode: `high-risk`
- Status: `READY`
- Reviewed pages: [1, 3, 4, 5, 6, 8, 10, 11]
- Reviewed blocks: 118

- `critical` `reference_span_error`: block appears inside the logical reference reading-order region
- `critical` `reference_span_error`: block appears inside the logical reference reading-order region
- `major` `same_page_boundary_error`: page contains mixed body/reference/tail signals
- `minor` `render_mapping_error`: some render-default blocks are not easily mapped into the current fulltext output
## Disposition Guidance
- Use `repair` when the finding reflects a pipeline defect worth fixing now.
- Use `residual` when the finding is real but intentionally deferred.
- Do not rewrite expected truth to make current output look correct.

- `major` `same_page_boundary_error`: page contains mixed body/reference/tail signals
- `major` `same_page_boundary_error`: page contains mixed body/reference/tail signals
- `major` `same_page_boundary_error`: page contains mixed body/reference/tail signals
- `major` `same_page_boundary_error`: page contains mixed body/reference/tail signals
- `major` `object_ownership_error`: ambiguous or unresolved object ownership remains in the current artifact set
- `minor` `render_mapping_error`: some render-default blocks are not easily mapped into the current fulltext output
## Disposition Guidance
- Use `repair` when the finding reflects a pipeline defect worth fixing now.
- Use `residual` when the finding is real but intentionally deferred.
- Do not rewrite expected truth to make current output look correct.

# OCR Truth Audit Report - 2AGGSMVQ
- Mode: `high-risk`

- `critical` `reference_span_error`: block appears inside the logical reference reading-order region
- `critical` `reference_span_error`: block appears inside the logical reference reading-order region
- `major` `same_page_boundary_error`: page contains mixed body/reference/tail signals
- `major` `object_ownership_error`: ambiguous or unresolved object ownership remains in the current artifact set
- `minor` `render_mapping_error`: some render-default blocks are not easily mapped into the current fulltext output
## Disposition Guidance
- Use `repair` when the finding reflects a pipeline defect worth fixing now.
- Use `residual` when the finding is real but intentionally deferred.
- Do not rewrite expected truth to make current output look correct.

- `major` `same_page_boundary_error`: page contains mixed body/reference/tail signals
- `minor` `render_mapping_error`: some render-default blocks are not easily mapped into the current fulltext output
## Disposition Guidance
- Use `repair` when the finding reflects a pipeline defect worth fixing now.
- Use `residual` when the finding is real but intentionally deferred.
- Do not rewrite expected truth to make current output look correct.

## Disposition Guidance
- Use `repair` when the finding reflects a pipeline defect worth fixing now.
- Use `residual` when the finding is real but intentionally deferred.
- Do not rewrite expected truth to make current output look correct.

# OCR Truth Audit Report - 2H8MZ27H
- Mode: `high-risk`
- Status: `READY`
- Reviewed pages: [1, 2, 3, 4, 5, 6, 7, 8]
- Reviewed blocks: 190
## Findings
- `major` `frontmatter_error`: frontmatter page retains elevated unknown_structural density
- `major` `same_page_boundary_error`: page contains mixed body/reference/tail signals
- `major` `same_page_boundary_error`: page contains mixed body/reference/tail signals
- `major` `object_ownership_error`: ambiguous or unresolved object ownership remains in the current artifact set
- `minor` `render_mapping_error`: some render-default blocks are not easily mapped into the current fulltext output
## Disposition Guidance
- Use `repair` when the finding reflects a pipeline defect worth fixing now.
- Use `residual` when the finding is real but intentionally deferred.
- Do not rewrite expected truth to make current output look correct.
