What happens in Xero when I apply a chart fix — and which ones ask first?

A rename changes the label only, and a create adds the account — neither asks. Fixing a code recodes the account in Xero and heals Saral's ledger so history re-files under the new code on both sides; crossing between Balance Sheet and P&L restates reports, and anything outside Saral keyed on the old number (the accountant's mapping) needs the same change. A retype re-heads prior periods when the account has transactions. An archive is offered only for a duplicate with no transactions. Codes, types and archives ask first and name the organisation. A batch runs one change at a time under Xero's rate limit.
