Salvage of #77660 covers quotes of INBOUND media via the bridge's download
cache. The reported case is the other half: a user quotes an image the bot
sent (a cron-delivered chart) and asks "what is this?" — the bridge cache
knows only inbound messages, and Meta's Cloud webhook ``context`` carries
only the quoted wamid, so the agent received a text-only turn and could not
see the image it had itself delivered.
Widen ``gateway/rich_sent_store`` (already the (chat_id, message_id) → text
index Telegram and the Cloud adapter use for quoted text) with
``record_media`` / ``lookup_media``: both WhatsApp adapters index the local
path + MIME of every media send at send time and every inbound media
receive, and on a quoted reply fold the resolved ``(path, mime)`` into the
event's own ``media_urls``/``media_types`` so the existing vision/audio
pipeline handles it like a direct attachment. ``lookup_media`` drops entries
whose file no longer exists. Baileys: the outbound index is the fallback
when the bridge cache misses; the cache-dir guard stays on bridge-supplied
paths only (our own sends are paths we chose). Cloud: link sends (public
URL, no local bytes) are not indexed.
One invariant test per adapter, red on origin/main.
