CI lint's format-check on added files (base-range dependent) failed on files that predate the format gate's effective coverage. Formatting-only: no semantic changes; integration tests 15/15, ruff check clean, ratchet PASS, daemon convergence re-verified.

"""install_wr_daemon.py — REAL_ASYNC_BRIDGE §6: daemon governance.
|
|
|
|
Canonical source lives IN THIS REPO at bridge/daemon/. The active install
|
|
is ~/.local/share/mimo-wait-resume/. This script is the ONLY supported
|
|
way to move code between them:
|
|
|
|
- copy canonical source → install dir (atomic, per file)
|
|
- verify sha256 convergence (fail loud on divergence)
|
|
- optionally restart the daemon via scripts/start_wr_daemon.py
|
|
|
|
Never hand-edit the installed copy: edit the repo source, install, restart.
