/**
|
||
|
|
* Upload-side ingest path.
|
||
|
|
*
|
||
|
|
* BROWSER SURFACE — not part of the headless ingest core. This is a thin
|
||
|
|
* wrapper over the headless `ingestPdf` that additionally pushes the bytes
|
||
|
|
* into a per-session `PdfByteStore`, which mints a `blob:` URL and stamps it
|
||
|
|
* onto `document.uri` so a viewer adapter can mount the PDF directly.
|
||
|
|
*
|
||
|
|
* 1. Read `file.arrayBuffer()` once into a `Uint8Array`.
|
||
|
|
* 2. Run the existing `ingestPdf(bytes, { filename })` pipeline to produce
|
||
|
|
* `{document, representation}`.
|
||
|
|
* 3. Push the bytes into the per-session `PdfByteStore`.
|
||
|
|
* 4. Hand the engine inputs back to the caller, which wires them via
|
||
|
|
* `engine.documents.register(...)`.
|
||
|
|
*
|
||
|
|
* Keeping URL-minting inside the byte store (rather than at the call site)
|
||
|
|
* means there is exactly one place that creates `blob:` URLs and exactly one
|
||
|
|
* place that revokes them.
