const USAGE = `
daemon-relocation-spike — minimal relocated daemon-host file-set probe (Windows)

Usage:
  node tests/tools/daemon-relocation-spike/spike.mjs --app-dir <win-unpacked> --work-dir <temp out> [--tier <t>]
  node tests/tools/daemon-relocation-spike/spike.mjs --selftest

Required (launch mode):
  --app-dir <path>    Path to a packaged win-unpacked build (contains Orca.exe)
  --work-dir <path>   Scratch dir for the copied host + logs (created, then removed)

Options:
  --tier <t>          File-set tier to copy: "full" (default), "no-gpu", "minimal"
                        full    = Orca.exe + icudtl.dat + both snapshot blobs +
                                  ALL top-level *.dll + daemon bundle + node-pty
                        no-gpu  = full minus GPU/render DLLs (libEGL, libGLESv2,
                                  vk_swiftshader, vulkan-1, d3dcompiler_47);
                                  ffmpeg.dll kept
                        minimal = Orca.exe + icudtl.dat + both snapshots +
                                  daemon bundle + node-pty only (no top-level DLLs)
  --keep-work-dir     Leave --work-dir on disk after the run (for inspection)
  --selftest          Validate arg parsing, tier defs, and the module-path filter
                        against synthetic inputs. No real build or launch. Exits
                        0 on pass, non-zero on failure.
  -h, --help          Show this help

Exit code is 0 only when the run PASSES: daemon ready, PTY echo round-trips the
nonce, and NO loaded module resolves under --app-dir.
