How it works
Apply the selected protocol’s token and multi-token wildcard rules. MQTT shared subscriptions use their underlying filter; root wildcards exclude $ topics.
The MQTT example matches the temperature and system topics once each, producing two topic/binding pairs.
Limits
At most 100 filters and 100 keys, each with 64 tokens. This matcher excludes whitespace/control characters and empty dot-separated tokens. No broker, permissions, delivery ordering or QoS simulation.
