The capture failures worth debugging are all about what Telegram did not deliver: a reply stripped of its content, a caption where text was expected, or a kind that falls through the switch. None of that is visible from the user-facing refusal, which only says "unsupported". One alias_capture line per /alias reports field names, lengths and counts — never message text, so aliased messages cannot travel with the logs.
