A cron job fired, the scheduler logged "delivered to telegram:<chat> via
live adapter", and nothing reached Telegram (#77763). The log line was not
evidence of a send:
* the silence-narration filter returns {"success": True, "delivered": False}
(a successful *drop*), and the dict-normalization branch read only
"success", so a filtered message counted as delivered;
* an empty payload (no text, no media) skipped the send entirely and still
fell into the "delivered" branch;
* the log line named the chat but not the lane, so a wrong-thread delivery
and a phantom one are indistinguishable after the fact.
_confirm_adapter_delivery now inspects both result shapes: an explicit
`delivered: False` is a rejection even with a truthy `success`, and a
success with no message_id and no raw_response is accepted but logged as
UNVERIFIED. The empty-payload case fails closed into the existing
standalone/warn handling, and the delivered log carries thread= and
message_id=.
Failing closed on the live lane is only half the fix on a native target:
the standalone fallback sent the same empty payload, and the Telegram
adapter returns SendResult(success=True) for empty content without an API
call — a phantom live delivery became a phantom standalone one. Both
_send_to_platform call sites now sit behind one skip guard, so "empty
payload fails closed" holds on every lane (#77763).
