Lets operators fix corrupted capture dates at scale. Adds an editable Date Taken field with a folder/filename-derived suggestion hint, a bulk Date Taken section in the multi-select sidebar that either applies one date to the whole selection or infers a per-photo date from each path, a warning badge on thumbnails whose stored date disagrees with the path, and a "Date issues" filter pill so suspicious photos can be surfaced and fixed as a group. Edits are written back to EXIF on disk so rescans don't clobber the fix. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

EXIF write-back helpers.

The rest of the app reads EXIF at scan time and stashes the result in Postgres
|
|
(see `services/metadata.py`). This module handles the reverse direction: when
|
|
the user corrects a date in the UI we also rewrite the relevant EXIF tags on
|
|
disk so a later rescan won't clobber the fix and external tools see the same
|
|
truth the DB does.
