framework
JavaScript library for creating and modifying PDF document structure — pages, metadata, annotations, form fields — which refuses to load encrypted documents and does not render pages.
No evidence-backed relationships are recorded.
For months the pipeline answered in four or five seconds with the right page count and no error, while recall against a known word list sat at zero. Five faults were stacked downstream of recognition, three of them silent by design.
Reality
A browser-only invoice generator assembles the header, objects, cross-reference table and trailer itself, skipping libraries its author puts at 300KB-plus, and its escaper drops anything unmappable to a question mark.

The fourteen standard PDF fonts are Windows-1252 underneath, so a Polish company name throws an encoder error, and the one-line regex that stops the crash ships a valid invoice with the letters quietly gone.
Reality
A dev.to writeup on browser-side PDF work argues the library's escape hatch for protected files returns structurally incomplete documents instead of an error. Silent corruption is worse than no output.
