dsh-multiprovider

When a DeepSeek Harness provider plugin must juggle multiple credentials, dsh-multiprovider centralises account selection, session affinity, health tracking, and cooldown policy into a single transparent scheduling layer so callers can focus purely on their workflow. A caller leases one account for a complete operation, settles the outcome exactly once, and explicitly reacquires only when failover is provably safe, eliminating the replay risks of hidden automatic retries.

It ships four deterministic selection policies (round-robin, smooth weighted round-robin, least-in-flight, and priority), optional session or workload affinity, and live visibility into cooldowns, failure classes, and in-flight counts. Credential references remain opaque locators on the host side and never leak into browser snapshots. Operators can enable or disable accounts, tune weights and priorities, switch selection policies, and clear automatic cooldown or health flags from a dedicated Accounts section inside the DSH Settings modal.

If you run DeepSeek Harness and need to schedule multiple API keys, OAuth tokens, or service accounts behind a single provider identity, or if you are building a provider plugin and want to delegate multi-account orchestration out of your own code, this is the component built for that job.
