Counts successful non-WebSocket bot responses (persisted in the metadata
table as survey_bot_response_count, survives restarts) and fires the
bot_response_success_100 survey event once the instance reaches 100
responses. Counting stops after the milestone has been triggered.
Existing first_bot_response_success behavior unchanged. 6 new unit tests.
* feat: add in-product survey system
- SurveyManager: event-based trigger, Space API communication
- Trigger on first successful non-WebSocket response
- Backend API: /api/v1/survey/{pending,respond,dismiss}
- Frontend: floating survey widget with progressive questions
- Flat radio/checkbox style (not dropdown Select)
* fix: persist triggered survey events to disk across restarts
Store triggered events in data/survey_triggered_events.json so that
restarting the process doesn't re-query Space for already-triggered events.
* fix: use metadata table for survey event persistence instead of file
Store triggered events in the existing metadata KV table
(key='survey_triggered_events') instead of a standalone JSON file.
* fix: ruff format and prettier fixes
