Search for files in Phabricator

Get metadata about a file (name, size, MIME type, URI). Use the returned URI to download. Provide at least one of id or phid. Uses file.info (the only Conduit method that returns download URIs).

Search Harbormaster buildables (objects that can be built, like revisions or commits)

Search Harbormaster builds (CI/build results)

Search Harbormaster build targets (individual build steps within a build)

Search Harbormaster build logs (output from build steps). Use phabricator_build_target_search to find target PHIDs first.
