Probed, not reasoned: a `creator` arriving as a STRING rather than an object makes jq exit 5
("Cannot index string with string"). That already failed closed — the abort lands before the
comment — but with only jq's stderr, which never says a status was left standing on the head.
Each extraction now carries its own message.
The no-creator refusal said the status "is how a status posted by an ACTIONS token appears".
Three shapes reach that branch (`creator` absent, null, or an empty login) and only one of
them is an Actions token, so the message now states the fact first and offers the cause as
the likely one rather than the established one.
