- Reject non-finite numerics at protocol parse and in the engine
(a 1e400 seek became Infinity and broke every broadcast).
- Reject empty swaps; sanitize URL-looking media names.
- Blank password = open server; defaults no longer 'change-me'.
- Loopback peers (the in-process host) can't be kicked.
- /health no longer exposes media/transport; file URLs use the
host the client dialled instead of 127.0.0.1.
- Count served bytes as streamed, not as requested.
