# UAT Result — S04

## Checks

| Check | Result | Notes |
|-------|--------|-------|
| Smoke test: `pytest tests/test_export/ -v` — 40 tests pass | PASS | 40 passed in 0.75s (13 models, 11 xlsx, 16 PDF) |
| 1. Default xlsx export produces valid workbook | PASS | Rows 1-5 contain metadata (Generated, Run ID, Source Type, Total Rules, blank). Row 6 is header row with 10 columns. Data rows start at row 7 with correct field values. Note: UAT spec said 8 columns but implementation has 10 (added Proposal ID + Approval Required); tests explicitly validate 10. |
| 2. Custom template xlsx export fills user template | PASS | Template headers (Source, Destination, Port) preserved in row 1. Data rows inserted below in matching columns with correct values (10.0.1.0/24, 10.0.3.10/32, 22). |
| 3. PDF export produces formatted document | PASS | File starts with `%PDF-`. Contains title "Firewall Change Request", run_id, source type, rule count, proposal IDs (prop-001), action values (CREATE, UPDATE), protocol (TCP). Verified via zlib FlateDecode decompression. |
| 4. Empty proposals produce valid files | PASS | xlsx: valid workbook with metadata rows, max_row=6 (no data rows). PDF: valid `%PDF-` file with metadata and "No rules proposed." message. |
| Edge: Missing proposal for a decision | PASS | Orphaned decision (prop-MISSING) silently skipped — no error raised. 1 valid entry returned for prop-001. |
| Edge: Invalid output path | PASS | `ExportError` raised with `error_code="XLSX_EXPORT_FAILED"` and details containing `output_path` and `rule_count`. |
| Edge: Invalid template path | PASS | `ExportError` raised with `error_code="TEMPLATE_LOAD_FAILED"` and details containing `template_path`. |

## Overall Verdict

PASS — All 7 UAT checks and 40 automated tests pass. Export package correctly produces xlsx (default and custom template) and PDF change request forms from pipeline state with proper error handling.

## Notes

- The UAT spec described "8 columns" in Check 1, but the implementation has 10 columns (Source, Destination, Port, Protocol, Direction, Action, Justification, Risk, Proposal ID, Approval Required). The tests (`test_column_count`, `test_header_row_content`) explicitly validate 10 columns. This is a minor documentation inaccuracy in the UAT spec, not a code defect.
- PDF content assertions require zlib decompression due to fpdf2's FlateDecode compression, as documented in UAT notes.
- The 2 pre-existing moto import failures (`test_aws_sg_adapter.py`, `test_s3.py`) are M001 issues, confirmed unrelated to S04.
