Bimonthly Townhall Report: Duriano

1. Executive Summary

Over the last two months Duriano shifted from launch hardening into live-operations and scaling. The headline outcome is a complete cloud-save rework that makes cross-device play and real-money purchases safe, the go-live of Google Play Subscriptions and the Redeem Code system, and the multiplayer foundation clearing Phase 0 and Phase 1a. A concentrated stability push — including a Unity 6000.3.19f1 engine bump, a fix for a high-impact Android pause ANR, and a Mali GPU soft-particle regression — carried the build through nine patch releases.

2. Cloud Save & Cross-Device Sync — the flagship

• No-progress-lost merging: Replaced the old conflict heuristic with a field-merge resolver — monotonic subsystems max/union, the fertilizer purchase ledger unions by order id, prefs/run use recency, and consent OR-merges.
• Real-money safety: An idempotent order-id PurchaseLedger with reconstructable balance; spends are derived from merged state so divergent offline spends can never under-count into free currency.
• Multi-account: Per-account local saves keyed by platform account id, with guest-save fallback when sign-in is declined and isolated PlayerSave_Demo for the Steam demo.
• Conflict hardening (July): Cloud pushes now merge instead of overwriting the other device's progress (Android GPGS + iOS KVS), identity/flag defaults can't beat real values, and a finished/empty run can't beat an unfinished one.

3. Monetization & Player Access

• Subscriptions: Google Play Subscriptions launched with an upgrade path for existing full-game owners; benefits evolved into a rotating weekly free roster (Character / God / Weapon) driven by a single Remote Config key.
• Redeem Codes: Full in-game redeem flow (UI, sound, layout) on the client, backed by a server-validated Firestore transaction system.
• Free-player access: Free users can now play Ranked via unlock-condition exceptions.
• Steam Demo: IsDemoVersion flag, demo app id, and isolated demo saves for the Steam demo build.

4. Multiplayer Foundation

• Phase 0 — Network Bootstrap: NGO + UGS Relay/Lobby integrated, the unified Multiplayer Services SDK adopted, an ISessionService seam for swappable connectivity, and a networked MP_Spike scene + player prefab.
• Phase 1a — Enemy Targeting: PlayerRegistry + nearest-player targeting so bosses/specials engage the nearest live player.

5. Stability, Performance & LiveOps

• Engine upgrade: Unity 6000.3.19f1, resolving the RockTrap reactivation crash (Unity issue UUM-143658).
• Android ANR: Fixed the app-pause ANR by pre-warming FMOD's core P/Invoke bindings out of the surface-teardown critical section.
• Crash sweep: God & Fate info-panel infinite recursion, RockTrap/debris stale-rigidbody crashes, and pooling bugs (skipped slots, stale button events).
• Mali GPU: Resolved VFX/soft particles vanishing on Mali (Poco X7 Pro) via an adaptive SoftParticleGuard.
• Observability: Firebase Crashlytics + Sentry Unity integrated; Game Analytics events expanded and batched.
• Force-update gate: Remote-Config-driven minimum-version gate that fails open when offline.

6. CI/CD, Build & Platform

• Addressables pipeline overhaul: Stabilized the CI player build — build-target-group switching, -buildTarget flags, and locking the Addressables build state to prevent pipeline conflicts.
• Google Play AAB: Upload lane with Unity IL2CPP symbols + release-stage validation.
• Multi-store: Deployment parameters for Android, iOS, Epic, Steam, and Xbox.
• Releases: v1.1.0 → v1.1.8 across the period.

7. Backend / API (Duriano API)

• Redeem codes: Transactional claim (one-time-use + per-player) and an admin create endpoint; rewards read server-side, never trusted from the client.
• Ranking anti-cheat: Server-side validation with raw + run-length-independent ratio caps derived from real player data; rejected attempts logged to a blockedRankings collection; gold/kill cap tightened 300 → 50.
