DocFence 0.34.0

DocFence 0.34 adds a private, topology-validated inventory for relationship-bound OPC package thumbnail images.

DFP080 can require a clean handoff with no recognized thumbnail image; DFP081 protects an approved thumbnail baseline and detects payload, relationship, or image content-type changes without disclosing them.

Recognition is limited to the exact standard relationship types and internal image targets from a package or part relationship. Image bytes, paths, relationship sources/targets, content types, and digests never appear in reports. DocFence does not decode, render, classify, or predict client display of an image.
