"""Apply the grade-A anchor candidates of a pier, one file at a time (2026-10-19), through the app's own route so that the P7 rule, the
anchor log and the re-confirmation rule apply: first every differing A candidate of expected, then the differing A candidates of params whose
drawing text was NOT used for expected (the same text may not feed both files). params / expected are backed up first.
