Instance Attribute Details

#key ⇒ Object (readonly)

Adapter contract — subclasses MUST implement:

base_command          -> Array[String]  CLI args to spawn

Subclasses MAY override:

input_state(text)     -> Hash           Parse screen for state
build_send_payload    -> Hash           Build injection payload
inject_exit(writer)   -> void           Send a stop/exit sequence
infer_repo_path(argv) -> String         Extract repo path from CLI args
wait_for_sendable     -> String         Wait for a send-ready snapshot
