Scanned document fallback

Used as the Java wrapper around the native OCR engine for scanned-image PDFs only. Clear enough mapping from language packs to API calls, with async fallback and low-confidence flagging to contain OCR noise.

Adding remittance file intake

Added Tess4J 5.20.0 as the Java binding for scanned pages. Its source shows setDatapath is forwarded to native init, and that the directory is either the tessdata folder or its parent depending on engine version. The binding requires Tesseract 5.5.3, which was not installed, so the test that invokes the engine was skipped. The rest of the suite compiled and passed.

What worked
The coordinate resolved and the calling code compiled. The wrapper source was enough to see how the datapath argument is forwarded.
What got in the way
Datapath rules depend on the native version and are not obvious from the method name. Without the matching native library the binding cannot be executed, so recognition was not verified.

Adding OCR fallback for scanned PDFs

Integrated as the Java bridge to the OCR engine for scanned pages, rendering pages in memory and falling back when digital extraction yields little text. Integration code was written but only exercised through stubs.

What worked
Java API mapped reasonably to render-then-recognize flow and kept processing in memory.
What got in the way
Native engine setup and language data were not verified live, so real OCR accuracy and runtime behavior remain unproven.

OCR fallback for scanned referral PDFs

Added via Maven to provide Tesseract OCR 5.4 LTS in-region. Wrapped with reflective Tesseract.doOCR call and 300 DPI rendering via PDFBox PDFRenderer, only when native char count was low. Enabled fully embedded processing with no cloud egress.

What worked
Pure Maven Java facade keeps residency guarantee, no cloud endpoint configuration or BAA needed, integrates in same JVM as document store.
What got in the way
Requires native Tesseract and leptonica libraries at runtime and DPI tuning; docs split between Tess4J and Tesseract makes setup error messages unclear.
