# External Preflight Matrix
This folder contains a minimal scaffold to generate one sample PDF for each supported mode and run external validators.
## Included scripts
- `generate_mode_samples.php` generates sample PDFs for:
- `pdfx`, `pdfx1a`, `pdfx3`, `pdfx4`, `pdfx5`
- `pdfua`, `pdfua1`, `pdfua2`
- `run_preflight_matrix.sh` runs:
- `qpdf --check` when `qpdf` is available
- `verapdf --format text --flavour ua1|ua2` for PDF/UA samples when `verapdf` is available
- a custom PDF/X validator command when `PDFX_VALIDATOR_CMD` is set
## Usage
From the repository root:
```bash
make preflight
```
Optional PDF/X validator hook:
```bash
PDFX_VALIDATOR_CMD='my-pdfx-validator --mode "$MODE" "$FILE"' make preflight
```
The script runs the command through `bash -lc` with these environment variables set per file:
- `MODE`: the current conformance mode, for example `pdfx4`
- `FILE`: the generated sample PDF path
- `REPORT`: the report file path under `target/preflight/report/`
Optional custom output directory:
```bash
bash resources/preflight/run_preflight_matrix.sh /tmp/tc-lib-pdf-preflight
```
Reports are written under `target/preflight/report/` (or the custom output path).
## Notes
- This is a tooling scaffold for repeatable external validation runs.
- veraPDF is used here as an explicit PDF/UA validator, not as a PDF/X validator.
- Final compliance claims still require profile-specific preflight policies and manual review using your selected validation authority.
