Summary

pvollan works primarily on WebKit's process sandboxing and platform integration layer — sandbox profile contents, sandbox extension issuance, and the WebContent/Network process division of trust — with a secondary concentration in Site Isolation, specifically cross-origin iframe rendering and back/forward navigation restore. The security fixes cluster almost entirely on local file load authorization: a tight sequence in early July relocated the sandbox extension check for local file loads from the WebContent process into the Network process, tightened FormDataReference extension validation, and cut off temp-directory loads, a shape that reads as variant analysis over one trust-boundary flaw rather than unrelated reports. Systematic-variant candidate: other paths that mint or consume sandbox extensions outside `NetworkResourceLoader::startNetworkLoad`, and the Site Isolation back-navigation restore code, which has absorbed repeated re-fixes for the same symptom across several months.
