The filename date class is now first-class (ADR-0001):
- memories::extract_date_from_filename returns FilenameDate:
Wall(NaiveDateTime) for the screenshot/dash/compact patterns,
Utc(DateTime<Utc>) for the unix-timestamp patterns. No patterns
added or removed; every existing pattern carries its convention.
- Waterfall inversion in both resolve_date_taken and
resolve_dates_batch: an in-class name is the original date of
record and resolves BEFORE EXIF / container dates are consulted
(shared filename_class_resolved step; in-class files skip
exiftool entirely). Wall patterns run the offset cascade over the
kamadak prior's evidence (empty evidence -> server-zone
assumption, so a class file always resolves); timestamp patterns
are true instants (tz_source utc_direct, no offset).
- Legacy date_taken stays byte-identical: wall-as-UTC for wall
patterns, epoch for timestamp patterns, via
FilenameDate::legacy_datetime / legacy_timestamp at the seven
consumer call sites.
- Out-of-class files keep the global EXIF-wins waterfall unchanged.
- CLAUDE.md waterfall section rewritten (step 0 = filename class;
the EXIF-beats-filename note becomes out-of-class-only).
Tests: five new waterfall-seam tests (wall no-evidence ->
assumed_server; wall outranks EXIF with offset-tag evidence;
wall GPS evidence; timestamp utc_direct; in-class video name
resolves without exiftool) plus enum-shape assertions in every
extractor test. Code-reviewed on both axes (standards: no
violations, 3 of 4 P2 notes applied; spec: all acceptance
criteria verified, no scope creep).
716 integration + 639 lib tests pass; fmt + clippy clean.
