Security & redaction
Structural redaction · DRM · watermark · audit log
Structural removal from the PDF byte stream — not CSS overlay. Pluggable adapter so the burn can run against the bundled TruPDF document service or your own backend.
F.01 — What you get
- No visual-only fallback: if the structural adapter is unreachable, the burn refuses.
- Append-only AuditLogger fired BEFORE bytes are returned.
- Watermark drawn into the content stream — survives flattening in every viewer.
- DRMEngine permission gate with maxOpens / expiresAt enforcement.
