Mutation

Re-walk the subledgers and store the result, then return it.

The read above reuses the stored measurement while the ledger has not moved under it, so this is for what that cannot see: a bank reconciliation finalized elsewhere moves the bank rail without posting anything. It is a mutation rather than an argument on the query because it writes — the stamp every reader of this workspace sees afterwards is the one this call left behind.

Returns FinanceTieOutHealth !.
