A: PoseAdapter.set_confidence_threshold is applied on start, so the
settings model-confidence field actually affects inference.
B: config source.mode ('stream'|'replay') is explicit; app no longer
guesses the source type from the URL prefix.
C: FallStateMachine takes a session_id and from_config generates a
unique one per run, so event ids never collide across restarts
(no screenshot overwrite or duplicate JSONL identity in a day).
51 tests pass.
