#### November *28, 2025**:-*** Behavioral Flagging Enhancements & Referral Funnel Visibility

### Purpose

To deepen Tapzi’s fraud detection signals using player behavior modeling, extend the visibility of referral performance, and improve system performance under sustained beta user load.

***

### Key Highlights

**🔍 Behavioral Flagging Pipeline Expanded**

* Backend now tracks anomalous pacing, click heatmaps, and “perfect play” ratios.
* Data is anonymized and visualized in Grafana dashboards.
* Edge-case replays flagged for admin review feed directly into trust scoring.
* Expanded device fingerprint coverage to distinguish legitimate input quirks from automation.

**📣 Referral Analytics Dashboard (Alpha)**

* Admin view added for top referring users, invite conversion rates, and referral-match correlation.
* Referral-based cohorts tracked through first win/loss, DNF rate, and engagement span.
* Attribution now includes UTM/campaign support.

**📱 Mobile UI Stability Fixes**

* Beta app bar interactions stabilized on Android and iOS Safari.
* Screen resize and orientation switch no longer breaks routing or scroll state.
* Referral input screen now loads as modal for smaller screens.

**⚙️ Internal Ops Reliability Sprint**

* Cron jobs for match cleanup, replay queueing, and telemetry roll-up now retry on failure.
* Health alerts for replay flag spikes and referral surge auto-pause implemented.

***

### Why It Matters

* Improved anti-bot measures reinforce Tapzi’s “skill-first” ethos without penalizing legitimate users.
* Visibility into referral-driven behavior supports growth planning and influencer outreach.
* Mobile compatibility ensures wider accessibility and retention during early adoption.
* Ops automation keeps the lean dev team efficient under scaling beta usage.

***

### Open Issues

* Behavioral scoring thresholds under review—some “fast click” users from APAC flagged too aggressively.
* Referral stats load slowly during cross-timezone cohort fetches.
* Replay flag accuracy not yet benchmarked against final mod decisions.

***

### Fixed

* Tournament double-start bug patched when resumed from soft error.
* Graph labels in referral dashboard no longer clipped in Safari.
* Anti-bot logs deduplicated for multiple flags from the same session.

***

### Next Steps

* Finalize scoring model for behavior-based flags with Trust & Safety audit group.
* Add leaderboard sorting by referral and flag resolution ratio.
* Begin surfacing trust indicators (e.g., verified fair-play badge) on user profiles.
* Launch internal test of onboarding heatmaps for new user path optimization.
