Vendor AiMessage exposed seven controls; the owned delegate had none, which
made patch 0008 a parity regression rather than a swap. Five are carried, two
are deliberately dropped:
regenerate — the conversation is forward-only and Ai.regenerate() is already
a no-op returning advice. A button whose only behaviour is to explain that
it does nothing is worse than no button.
edit — there is no in-place edit. The vendor's wrote to a local array the
server never sees, so the message read back was not the message held.
delete is kept but armed: removeMessage() splices two local arrays and leaves
the server transcript untouched, so it is a view filter wearing a delete icon.
The armed row says so in words and replaces the controls in place rather than
opening a modal, which on a layer-shell surface would fight for focus.
speak and copy are separated at the source. copy takes the whole content;
speak takes text segments only, so the synthesizer no longer reads reasoning
and tool payloads aloud. Legacy messages without segments fall back to full
content rather than to silence.
re-synthesize prefers Speech.resynthesize() when present and degrades to the
old stop+speak otherwise, because speak() opens with a cache check on the text
and re-synthesis is by definition the same text — the legacy path replays the
identical broken audio.
