AddStakeBurnRateLimitExceeded
Wait for the rate-limit window to pass, then retry
The add-stake-and-burn operation was submitted again before its per-key rate-limit window elapsed. Wait some blocks and retry; no active raise site exists in current code, so this mainly appears on older runtimes.
Declared by the SubtensorModule pallet; it classifies to the semantic code rate_limited.

The same explanation is available in the terminal: btcli explain AddStakeBurnRateLimitExceeded.
