Retry and Delivery Policies

Retry and delivery policies

Policy sections live under TwitchBot:Policies. They are required when the Twitch runtime is active.

Validation rules

• Attempt limits must be at least one.
• Delays, timeouts, delivery lifetime, and retention must be positive.
• Maximum delay cannot be shorter than the initial delay.
• Public-chat maximum age cannot exceed one minute.
• Backoff must be a defined Polly DelayBackoffType; the shipped value is Exponential.

Retries improve resilience but do not create an exactly-once guarantee. Expired, terminal, and ambiguous delivery outcomes remain visible to operations; see Runtime health and delivery.
