Module error_codes 

Canonical error codes emitted while opening a client route.

Error frames remain extensible strings, but these daemon-owned route-open outcomes need identical spelling across the daemon and SDK retry policies.

Constants

MODULE_NO_PROTOCOL

The target module is declared as speaking no subc wire protocol (protocol: "none" in daemon config), so it has no control lane and can never accept a route. The daemon supervises its process and nothing else.

MODULE_RELOADING

MODULE_REMOVED

MODULE_TIMEOUT

MODULE_WARMING

TARGET_UNAVAILABLE

UNKNOWN_MODULE

Functions

is_retryable_route_open

Whether a route.open refusal carrying code may be retried in place within the caller’s deadline, or is terminal for the target as named.
