  "message": "Add an archived representation for tree artifacts.\n\nTree artifacts are currently passed as individual files which are in the\ndirectory. This change is a prototype which allows to pass those directories\nusing a single archived file instead.\n\nAdd a new option which, if enabled, assigns an archived representation to each\nof the tree artifacts. The representation is a single file, which contains all\nof the files in the artifact (zip archive). Those files are added in a\ndirectory using a reserved name (containing a `:`), therefore cannot clash with\nuser-created files.\n\nExpand the TreeArtifactValue to enable storing the archived representation and\nupdate the inputs mapping code to include the archived file.\n\nAdd handling for changes to the archived files in `FilesystemValueChecker` to\nensure correctness in case of incremental builds, when the files get\nedited/deleted.\n\nAdd explicit errors for use cases for which archived tree artifacts are not\nsupported yet like inputs discovery, shared actions, action templates or\ndiscarding orphaned artifacts.\n\nPlease note that this feature relies on spawn runners to create the artifact\nitself -- using it with one which does not support it will result with an error\n(missing tree artifact output).\n\nAdd a new, parameterized category of tests for `FilesystemValueChecker` to\ncover handling of archived files. Improve reliability of\n`FilesystemValueChecker` by replacing the clock used to generate file `ctimes`\nfor files with a `ManualClock` (previously `JavaClock`, using\n`System.currentTimeMillis()`).\n\nPiperOrigin-RevId: 327472179\n",
