That reply's node was\nrecorded with no UI and fell back to turn-derived markdown on restore,\nlosing any display-only transformation.\n\nReplace `chat_history_on_response` with an `observeEvent` on the\n`_messages` input (mirroring Python's `@reactive.event(chat.messages)`)\nthat saves only once the browser reports a settled transcript ending in an\nassistant message. Add a regression test that drives the save purely\nthrough the `_messages` echo and asserts the displayed (transformed) UI\nis stored, not the fallback.\n\n* docs(pkg-r): explain why R keeps replay-suppression flags alongside the count guard\n\nThe count guard is steady-state idempotency; the is_replaying /\nsuppress_next_save flags guard the restore transaction, which the count\ncheck does not. Python can drop its flags because it does not re-send UI\nto the client on restore the way R does.\n\n* fix(pkg-py): raise on malformed reported messages instead of silent", "time": 1784916288 },
