Summary

pvollan works primarily on the platform and process-model layer — macOS/iOS sandbox profiles, sandbox extension handling, and the WebContent/Network process split — with supporting work in logging, syscall telemetry, and Darwin temp/cache directory plumbing. The security fixes cluster tightly around local file loads and sandbox extension validation: moving the extension check out of WebContent into the Network process, rejecting invalid extensions in the FormDataReference validator, stopping the Network process from minting its own form data extensions, and blocking unextended local file loads outright. That is a single boundary being reworked end to end, so the surrounding code — remaining callers that pass sandbox extension handles across IPC, and the temp-directory access paths recently restricted — is a promising area to sweep for related bugs.
