⚡ TSeason — The Complete Minecraft SMP Season Lifecycle Engine

🌟 Why Choose TSeason?

Running repeated seasons on modern Minecraft servers typically forces administrators to coordinate dozens of disjointed plugins, manual world deletions, custom broadcast scripts, and permission resets. A single server hitch or crash during a world wipe often leads to corrupted files, duped items, or ruined player data.

TSeason replaces this fragile, stressful manual ordeal with a deterministic, crash-resilient, commercial-grade season lifecycle engine that feels like a premium plugin while being completely free and open-source.

🚀 Key Feature Showcases

🎬 Synchronized Cinematic Launch Protocol

Launch your seasons with a thrilling, synchronized event that requires zero client-side mods:

• 10..9..8..1 Synchronized Countdown: Real-time broadcasts, multi-stage titles, and actionbar alerts.
• Dynamic Adventure BossBar: Live progress indicator with automatic color-shifting from Gold to Bold Red during the final 3 seconds. Mid-countdown joining players are automatically synced.
• Scaling Audio Pitch: Scaling note-block pitch (0.6f → 2.0f) with dramatic bell accents in the final stretch.
• Smooth Anti-Jitter Player Freeze: Coordinates are locked while camera/head rotation remains 100% fluid. Block breaking, placing, PvP, and item dropping are strictly locked until world opening.
• The World Opens Fanfare: Instantaneous simultaneous player release, multi-layered victory fanfare audio, totem and firework particle bursts, and automated transition to Grace protection.
• Instant Admin Cancel: Easily abort any launch countdown at any time using /tseason season cancel.

🛡️ Deterministic State Machine Engine

Every phase of a season is governed by a strict, validated transition matrix:

IDLE ➜ COUNTDOWN ➜ LAUNCHING ➜ GRACE ➜ ACTIVE ➜ ENDING ➜ ARCHIVED ➜ IDLE

• Safety Over Flashiness: Destructive operations (world resets, inventory purges) can never trigger accidentally or run concurrently.
• In-Flight Crash Journaling: State transitions are tracked in atomic transaction journals (transition_journal.json). If power fails or the server crashes, TSeason prompts administrators with safe rollback tools upon restart.
• Crash-Safe Atomic File Storage: Vaults, passports, and configuration snapshots are written using atomic temporary file swaps (.tmp → atomic filesystem swap) to guarantee zero file corruption.

🎒 Cross-Season Player Vaults (/tseason vault)

Reward loyal players by letting them safely roll over select items to the next season:

• Exploit & Dupe-Proof: Built on native Bukkit serialization with container nesting prevention (Shulker Boxes & Bundles blacklist) and strict item blacklists.
• Tiered Unlocks: Grant custom vault capacities per player rank using Vault / LuckPerms permission nodes.

📜 Seasonal Passports & Lifetime Progression (/tseason passport)

Build long-term community retention:

• Lifetime vs. Seasonal Stats: Tracks playtime, mob/player kills, deaths, achievements, points, and milestones across seasons.
• Zero-Tick Playtime Tracking: Calculates playtime using timestamp deltas on join and quit — absolutely zero per-tick timers.
• Archival Hall of Fame: Historical snapshots of top leaderboards are automatically generated and preserved when a season concludes.

⚡ Performance-First (Folia & Paper Native)

• Zero Idle Overhead: No chunk scanners, no repeating entity loops, and no per-tick world checks.
• Native Folia Support: Seamlessly utilizes Folia's GlobalRegionScheduler, RegionScheduler, and AsyncScheduler alongside Paper's main-thread schedulers.
• Microscopic JAR Footprint (~175 KB): Extremely fast startup and minimal RAM allocation.
