Minified MPV initialization aborted because callback keep rules retained obsolete JNI signatures. Android TV IME dismissal also left editing active, requiring an extra Back press to leave the screen.
Keep only the named JNI callbacks without duplicating argument signatures and exercise them through the permanent minified reachability gate. Centralize native editing-session termination, observe owning-view keyboard dismissal, and reject stale completion or reopening work.
Verified the minified gate on Galaxy Z Fold3, debug MPV lifecycle and log-level suites on SHIELD and Pixel 7, native Done/Previous and two-Back behavior on SHIELD and Fire TV, 76 focused Flutter tests, analyzer parity, and shrinker checks. Both new regressions reject the original implementations.
