AddMedia sized a file before validating its type, and ValidateSize's Unknown
arm returned the video message, so a 150 MB .exe sent as
application/octet-stream was rejected as FileTooLarge with "Videos must be
100 MB or smaller." EnsureAllowed now runs first, so an unsupported file always
reports UnsupportedMediaType, and the Unknown arm uses a type-neutral message.
The oversize controller tests now use real file headers so they pass the type
check before reaching the size cap.
Adds MediaCounts (limits, current photos/videos, and the counts a new
completion version would see) so the portal can refuse an 11th photo or
4th video before uploading it. Uses the same count and replacement rule
the upload check enforces.
Read the duration from the MP4/MOV movie header (moov/mvhd) on both the
dispatcher media endpoint and the vendor portal completion upload, so a
direct request cannot bypass the browser check. Unreadable metadata still
never blocks an upload.
The 10-photo / 3-video limit only counted dispatcher attachments, so vendor
portal uploads could push a work order past it (and vice versa). Count the
work order's current vendor documents alongside its attachments on both the
dispatcher media endpoint and the vendor portal. A new completion version
does not count the version it replaces.
A misleading file name could move a file into a larger size class: a real
PDF or JPEG named .mp4/.mov got the 100 MB video cap on the vendor portal,
and a .jpg declared with a foreign video type got it on the media endpoint.
Classify by the same resolved type the signature check validates; the
extension only decides when no allowlisted type is known.
The Elastic Beanstalk nginx proxy kept its 1 MB default body limit, so every
media upload over ~1 MB got an nginx 413 before reaching the API. Ship a
.platform nginx override (120M) in the bundle and assert it in the bundle
contract.
Apply the client-confirmed contract: photos up to 10 MB (JPEG/PNG/HEIC),
videos up to 100 MB (MP4/MOV), at most 10 photos and 3 videos per work order,
with stable generic rejection messages. The request ceiling (110 MB) sits
between the per-kind caps and the proxy so oversize files get the generic
message. The vendor portal accepts the same photo/video types and caps.
