DelegateTxRateLimitExceeded

The delegate changed its take again before the per-hotkey take-change rate limit elapsed. Compare blocks since the hotkey's last take transaction against the TxDelegateTakeRateLimit storage item and retry later.

Declared by the SubtensorModule pallet; it classifies to the semantic code rate_limited.

Remediation

Wait for the rate-limit window to pass, then retry
