"This day" sent the entry's calendar date to the provider as both bounds, and
both providers turned that date into a UTC window — Immich by concatenating a
Z suffix, Synology by relying on a date-only string parsing as UTC midnight.
For a reader at UTC+10 the searched window was 10:00 on the day to 09:59 the
next morning, so every breakfast photo was missing while the next morning's
turned up in its place, and nothing said the day was incomplete. The date
headings had the mirror defect, filing a 07:32 photo under the previous day.
Immich publishes the right anchor already: localDateTime is required on every
search result and is what its own timeline groups by. The window is padded by
a day on each side and the page narrowed again by each photo's own local date,
carried through as localTakenAt; a server that does not send it falls back to
the timestamp used until now, so nothing changes there. Because the padding
means raw rows and answered rows are no longer the same thing, the page is
filled server-side until it holds what the caller asked for, bounded so a
pathological album cannot spin.
Synology has no local stamp, so its anchor comes from the caller as a UTC
offset, resolved for the day being searched rather than for today — a day
looked up across a DST boundary would otherwise start an hour out. The MCP
tool takes the same optional input, defaulting to the behaviour it has now.
The picker's pagination sentinel moved out of the non-empty branch: a page the
new filter empties has to keep paging, and it now says so instead of claiming
there are no photos.
Closes#2336
The picker got its photos back in whatever order the provider happened to
return them. It groups by day and appends pages lazily, so an unordered page
lands under the wrong heading and pushes photos out of the fold the reader
is looking at.
Immich now asks for order: desc on both the search and the album path. An
older server that does not know the property drops it silently rather than
failing, so each page is sorted again here; the album paths drain every page
before sorting and are covered outright. getAssetInfo reports mediaType, the
same mapping the listing already used, so the detail route and the picker
agree on what an asset is.
Synology gets no sort parameter upstream on either path. Search.Search
documents none, and _fetchSynologyJson maps every app code except 106/107/119
onto a 400, so a parameter one DSM build rejects would take listing down
entirely for that user. Both paths read every page anyway, so ordering the
mapped result costs nothing and cannot fail.
No media type for Synology yet, deliberately. streamSynologyAsset serves
every asset as a JPEG out of SYNO.Foto.Thumbnail, original included; there is
no video byte path. Labelling an asset a video would make the lightbox mount
a player on a still image, which is worse than the missing badge. The badge,
the byte path and the persisted media_type belong together in their own
change.
Five album cases in the Immich integration suite pinned the old arrival
order. Where the position was incidental they now look the asset up by id;
where the order is the point they state the chronological one.
