`09` §3 decision 145. MARKER_IGNORE in upgrade-test.py: per app, the files the
files_may_change mark does not count — first immich's six 13-byte
{encoded-video,library,backups,profile,thumbs,upload}/.immich folder markers,
rewritten at every start (bench measurement 2026-09-30). A listed file is
ignored only when changed/added and still <= 64 bytes; a removed or grown
marker, any unlisted file, and a moved tree the file walk cannot name still
mark the step. The verdict records files_ignored with the reasons.
HARNESS_VERSION 5. Tests: test_upgrade_bench.py MarkerIgnore (red-proved).
