Module doctor 

Checks for the faults that cost real debugging time, and repairs for the ones whose correct value is discoverable.

The motivating case: Metro runs inside the container, but file events do not cross the bind mount from the host, so its watcher never sees an edit. The entrypoint’s poker exists to bridge that, and a stale METRO_POKE=false baked into a container turns it off silently - every change then needs a cache clear, with nothing to say why.

A .env line whose value holds unquoted spaces.

Constants

METRO_POKE

Functions

check_docker

check_env_quoting

check_metro_poke

check_overlays

check_root_apps

container_metro_poke

METRO_POKE as the named container actually has it, which is not always what the env file says: a container keeps the environment it was created with until it is recreated.

docker_available

fix

format_actions

format_checks

remove_env_key

Drop a key from a .env file, leaving every other line as it was.

run

running_metro_containers

runs_mobile

Does this workspace run a mobile app whose Metro lives in a container?

set_env_key

Set key in a .env file, preserving comments and the order of what is already there. Appends with a note when the key is absent.

undeclared_root_apps

Only the overlay generate always writes. docker-compose.extra.yml is written per extra app, so a workspace with none legitimately has no such file - demanding it would be a failure no repair could ever clear. Directories beside the frontend repo that look like runnable apps.
