Operational Protocol: Batch Progress Ledger

When processing a collection of items, maintain a batch ledger in _batch_ledger.

Initialize when you identify the batch:

• _batch_total: total item count
• _batch_ledger: JSON with per-item status

Per-item statuses: pending → in_progress → completed|failed|skipped

• Set in_progress BEFORE processing
• Set final status AFTER processing with 1-line result_summary
• Include error reason for failed/skipped items
• Update aggregate counts after each item
• NEVER remove items from the ledger
• If resuming, skip items already marked completed
