  "account": "The OpenClaw source code walkthrough begins with the entry.ts file at line 36, where the Gateway's auth.mode configuration and device-auth.ts play a role in handling startup flow. The program avoids crashing due to double startup by first checking if it's the main module; if not, the else block executes.\n\nInside the else block, the logic for starting the Gateway starts with a respawnWithoutOpenClawCompileCacheIfNeeded function. This function checks if the current Node process has enabled OpenClaw's compile cache. If not, a new child process is spawned with the cache enabled, and the parent process exits. If the child process restarts successfully, the parent process does nothing and exits. If the cache is already enabled or the child process doesn't restart, the program continues normally.\n\nAfter successful restart (or no restart needed), the program performs initialization steps such as setting process.title to \"openclaw\", ensuring the OpenClaw execution marker is set, installing a process warning filter, and normalizing environment variables. In the enableOpenClawCompileCache function, installRoot is called.\n\nA performance marker records the time taken from process start to bootstrap completion. The actual Gateway startup happens much later with runMainOrRootHelp → runCli(argv) → openclaw gateway run.\n\nThe source code checks if the command being run is secrets audit and sets up color output. It also handles OpenClaw's restart plan, parsing container arguments, file arguments, and handling the --version fast path. Finally, asynchronously executing tryHandleRootHelpFastPath and tryHandlePrecomputedCommandHelpFastPath handles help messages, and runMainOrRootHelp actually starts the Gateway after checking for fast paths and subcommands.",
