SISCHOI/daruma#dsh-daruma

Keeps long DSH sessions alive when a model channel starts failing: daruma takes over after the in-box retry gives up, trips a self-healing circuit breaker on repeated 429/5xx or a terminal error, and moves the next request to another channel in your chain. Works on DSH 0.1.x and 0.2.x hosts, including 0.2.1-rc.2 with verified failover and backup-management RPC. The backup can be picked in Settings or from a panel beside the composer — both stay in sync — with a durable JSONL audit log for every switch. Channel switches are recorded in that audit log instead of as in-conversation notice rows, because a plugin session event of a type the host does not know makes it refuse to load the whole session.
