+lotus-shed chainindex validate-backfill --from <start_epoch> --to <end_epoch> [--backfill] [--log-good] [--quiet]
 
 The command validates the chain index entries for each epoch in the specified range, checking for missing or
 inconsistent entries (i.e. the indexed data does not match the actual chain state). If '--backfill' is enabled
 (which it is by default), it will attempt to backfill any missing entries using the 'ChainValidateIndex' API.
 
-Parameters:
-  - '--from' (required): The starting epoch (inclusive) for the validation range. Must be greater than 0.
-  - '--to' (required): The ending epoch (inclusive) for the validation range. Must be greater than 0 and less
-                        than or equal to 'from'.
-  - '--backfill' (optional, default: true): Whether to backfill missing index entries during validation.
-  - '--log-good' (optional, default: false): Whether to log details for tipsets that have no detected problems.
-
 Error conditions:
   - If 'from' or 'to' are invalid (<=0 or 'to' > 'from'), an error is returned.
   - If the 'ChainValidateIndex' API returns an error for an epoch, indicating an inconsistency between the index

   - If '--log-good' is enabled, details are also logged for each epoch that has no detected problems. This includes:

 This command is useful for backfilling the chain index over a range of historical epochs during the migration to
 the new ChainIndexer. It can also be run periodically to validate the index's integrity using system schedulers
 like cron.

+If there are any errors during the validation process, the command will exit with a non-zero status and log the
+number of failed RPC calls. Otherwise, it will exit with a zero status.
