 ### Added
 
+- **`PassProgress` is the complete, mapfile-free progress contract.** Every
+  emission now carries the fully-rendered "where is the damage" drilldown
+  (`located`): the bad ranges annotated with chapter + movie-time offset, the
+  main-feature at-risk time, the section count and the largest gap — computed by
+  the library from its in-memory mapfile + title. A client (autorip, a future
+  GUI/CLI) renders the disc map + at-risk time straight from it and never parses
+  the mapfile, so a mapfile→mapdb change is invisible to clients. Adds
+  `disc::locate_ranges`, the one-shot `disc::progress_snapshot_from_mapfile`
+  (builds a snapshot from a mapfile on disk so a boundary/verdict paint stays
+  mapfile-free client-side), and `consts::MILLIS_PER_SEC`.
