+# MariaDB Persistence & Dynamic Achievement System Plan
+
+Comprehensive architecture and design blueprint for integrating a MariaDB Galera cluster backend, implementing dynamic achievement recalculation on round deletion, and introducing a two-phase provisional vs. finalized achievement tracking engine during live rounds.
+
+---
+
+### User Review & Critical Decisions
+
+> [!IMPORTANT]
+> The architectural directions confirmed during Phase 1 have been integrated:
+> - **Database Backend**: Configured for your existing **MariaDB Galera Cluster** via standard Node.js connection pooling with failover resilience, plus an automated schema migration runner and a dev-mode fallback when credentials are not yet set.
+> - **Round Deletion & Achievements**: Deleting a saved round dynamically **recalculates achievements** across all remaining completed rounds, revoking badges if their qualification criteria are no longer met.
+> - **In-Round Instant Badges (e.g. Hole-in-One)**: Celebrated instantly with a live in-round toast upon entry, held as **provisional** during active scoring, revoked if the hole score is modified prior to saving, and permanently committed only upon confirmed round finalization.
+
+---
+
+## 1. Overview & Core Concept
+
+### What It Does
+Pinpoint Golf evolves from a local session tracker into a production-grade multi-device golf companion backed by a dedicated MariaDB Galera cluster. It introduces:
+1. **MariaDB Persistence Layer**: Secure user profiles, rounds history, hole-by-hole stats, and verified career achievements stored persistently in MariaDB tables with transactional integrity.
+2. **Dynamic Career Recalculation Engine**: When a saved round is deleted, the backend re-runs the achievement rules against all remaining saved rounds, ensuring career records and trophies strictly reflect actual saved history.
+3. **Two-Phase Live Achievement Engine**: High-impact milestones (like a Hole-in-One, Eagle, or Birdie Streak) trigger immediate in-round celebration banners. If a player corrects a typo before submitting, the provisional award is retracted. When the round is finalized with confirmation, all verified milestones are locked into the database.
+
+### Target Persona & Key Value
+- **Avid Golfers**: Enjoy real-time excitement during live scoring without fear of permanent false entries due to typing errors.
+- **System Administrators / DevOps**: Benefit from standard MariaDB Galera multi-master clustering support with zero lock-in and zero mock data in production.
+
+---
+
+## 2. User Experience & Visual Design
+
+### Live In-Round Achievement Workflow
+```
+[ Hole Entry Modal ]
+        │  Enters score: "1" (Ace / Hole-in-One)
+        ▼
+[ Instant Celebration Banner ]
+  • Dynamic toast: "🎉 Hole in One! (Provisional)"
+  • Visual indicator on Hole card: "Provisional Ace"
+        │
+        ├── User corrects score to "3":
+        │     └── Toast: "Provisional badge retracted" (Ace badge removed)
+        │
+        └── User finishes round & clicks "Save Round":
+              └── SaveRoundModal confirmation
+                    └── Achievements committed permanently to MariaDB
+```
+
+### Key User Flows & Visual Hierarchy
+1. **Live Hole Entry & Provisional Badges**:
+   - Scoring controls remain ergonomic for one-handed mobile thumb usage ($44\text{px}+$ touch targets).
+   - Instant achievement toasts use rich typography (`Plus Jakarta Sans`), subtle entrance transitions, and non-blocking dismissals.
+   - Distinct visual state for provisional badges (clean amber/gold indicator with a subtle "Pending Round Finalization" cue; no pill enclosures).
+2. **Save Confirmation Gate**:
+   - The `SaveRoundModal` displays the round recap (gross score, net score to par, putts, FIR/GIR) and a list of new achievements earned this round.
+   - Clear warning: *"Saving locks this round permanently into your official record. Editing will no longer be possible; only deletion is allowed."*
+3. **Round Deletion & Dynamic Recalculation**:
+   - In `RoundsHistoryModal`, each saved round card provides a "Delete Round" action with a two-step confirmation prompt.
+   - Deletion dialog warns: *"Deleting this round will recalculate your career achievements. Badges earned solely from this round will be removed."*
+   - Immediate feedback toast: *"Round deleted. Achievements updated (X badges retained)."*
+
+---
+
+## 3. Key Product Decisions & Trade-Offs
+
+### Decision 1: MariaDB Galera Cluster Integration
+- **Approach**: Configure a robust Express-based database adapter using `mysql2/promise` with Galera-ready connection pool settings (keep-alive, reconnection retry logic, multi-host support).
+- **Environment Variables**:
+  - `MARIADB_HOST` (supports single host or comma-separated cluster nodes)
+  - `MARIADB_PORT` (default 3306)
+  - `MARIADB_USER`, `MARIADB_PASSWORD`, `MARIADB_DATABASE`
+  - `MARIADB_SSL` (optional SSL mode)
+- **Zero-Friction Fallback**: When `MARIADB_HOST` is not yet configured in local environment, the server falls back to an integrated local SQLite/JSON storage engine with identical schema interfaces, ensuring the app remains fully functional while credentials are provided.
+
+### Decision 2: Achievement Recalculation Engine
+- **Approach**: Pure deterministic recalculation function `calculateUserAchievements(savedRounds, courses)`.
+- **Why**: Storing achievement IDs as an append-only set risks "ghost achievements" where a deleted bogus round permanently leaves a Hole-in-One badge on the profile. By calculating career achievements dynamically upon deletion, data integrity is 100% mathematically sound.
+
+### Decision 3: Provisional In-Round vs. Finalized Achievements
+- **Approach**: Two distinct evaluation phases:
+  - **Phase A (Provisional)**: Runs client-side during active round edits. Evaluates single-hole feats (Hole-in-One, Albatross, Eagle, 3-Birdie Streak). Displays celebration toasts. If score drops below qualification, badge is removed from provisional state.
+  - **Phase B (Finalized)**: Runs server-side upon `POST /api/rounds` finalization. Evaluates both round-level feats (Sub-80, Clean Card, Centurion, Marathon) and verified hole-level feats, writing records transactionally to `user_achievements`.

+
+## 5. Implementation Roadmap (Post-Approval)
+
+1. **Backend Database Driver & Migration**:
+   - Add `mysql2` driver and create `src/server/mariadb.ts` with pool configuration and auto-table creation on startup.
+   - Configure `.env.example` with MariaDB connection parameters (`MARIADB_HOST`, `MARIADB_PORT`, `MARIADB_USER`, etc.).
+   - Support seamless fallback for development environments without an active cluster connection.
+
+2. **Provisional In-Round Achievement Engine**:
+   - Update `HoleEntry.tsx` and round state to evaluate single-hole feats in real-time.
+   - Add animated toast notification for provisional unlocks and graceful retraction notifications if scores are adjusted.
+
+3. **Round Finalization & Recalculation Lifecycle**:
+   - Wire `SaveRoundModal.tsx` to commit verified rounds to MariaDB and lock the round from future editing.
+   - Implement round deletion with automatic re-evaluation of user achievements, updating `user_achievements` in MariaDB and syncing client state.

+
+## 9. Clean Deployment & Data Integrity Rules
+
+To guarantee enterprise-grade data hygiene and tour-level integrity, PinPoint Golf enforces strict separation between development testing and production deployment:
+
+### 1. Mock Data Elimination in Production
+- **Server Store**: In production (`NODE_ENV=production` or `ENABLE_MOCK_DATA!=true`), the database manager `src/server/db.ts` suppresses demo accounts (`usr_demo_golfer`) and seeded community golfers (`user_seed_*`). Only real registered users and scorecards exist.
+- **Client App**: The client initializes rounds state to an empty list `[]` instead of pre-seeding `SAMPLE_ROUND`. The "Load Dev Sample Round" button is stripped in production builds (`import.meta.env.PROD`).
+
+### 2. Authentication-Gated Features
+The following features are exclusively unlocked for registered golfers:
+- **Community Benchmarks & Leaderboards**: Public comparison of handicap, FIR%, GIR%, putts, and scrambles against peers.
+- **Career Achievements & Trophies**: 22 tier-ranked achievements across scoring, accuracy, and short game.
+- **Satellite GPS Rangefinder**: Real-time Google Maps satellite flyover, Front/Center/Back green distance calculation, pin targeting, and shot distance measurement.
+- *Guests & Unauthenticated Users*: Can start rounds, view course scorecards, and check local play, but receive clear in-app prompts to sign in or create a free account to unlock GPS, community leaderboards, and trophies.
+
+### 3. Achievement Lifecycle Rules
+- **Empty Initial State**: New registered users start with zero achievements unlocked (`unlockedIds: []`).
+- **Finalization Requirement**: Achievements are never awarded during live play; they are evaluated and awarded **strictly upon finishing and saving a completed round** (`isCompleted: true`).
+
+### 4. Round Immutability & Deletion Workflow
+- **Confirmation Modal**: Clicking "Finalize & Save Round" triggers `SaveRoundModal`, showing a complete scoring summary and an explicit warning that the round will be permanently locked.
+- **Post-Save Immutability**: Once saved (`isCompleted: true`), hole scores and statistical inputs are locked against modification.
+- **Deletion Only**: The only permitted post-save action on a finalized round is deletion from the golfer's history with confirmation.
