Baileys' contextInfo.quotedMessage only ever carries a thumbnail-sized
stub for media, or nothing at all for an uncaptioned attachment — never
a way to fetch the original file. When a user replies to an earlier
photo/video/document/voice note with no caption on it (e.g. "did you
save this?" quoting an uncaptioned wedding invite image), the agent
saw no text and no media reference at all: it looked like the message
never had an attachment.
Add createQuotedMediaCache, a bounded in-memory cache (keyed by
chatId:messageId) of each inbound message's already-downloaded media
and text, populated as extractBridgeEvent processes every message.
When a later message quotes one of these, extractBridgeEvent resolves
quotedMediaUrls/quotedMediaType from the cache and falls back to a
human-readable quotedText ("sent an image", etc.) when the quote had
no caption to extract. The adapter folds resolved quoted media into
the event's own media_urls/media_types — reusing the existing
vision/audio pipeline and the existing _is_allowed_bridge_path path
validation — rather than adding a parallel reply-media code path.
Reimplements the same feature as #52875 (credit: dhruvkej9) against
current main, whose 11627fdcb refactor (native polls, locations, rich
inbound metadata) moved this code into bridge_helpers.js and made that
PR's diff no longer apply cleanly.
