Claude Code fast-mode retry policy overview

On 429/529 with a Retry-After under 20s, retry inline keeping fast mode active so the prompt cache survives the same-model retry. On longer or unknown Retry-After, trigger triggerFastModeCooldown(now+max(retry-after, 10min)) and disable fast mode for this attempt — the next call resolves to a standard-speed model. Permanent rejection (anthropic-ratelimit- unified-overage-disabled-reason) calls handleFastModeOverageRejection and drops fast mode for the rest of the session.
