TypeSafe Jev API & Spend Economics + +- **API Endpoint & Protocol:** + - Default URL: `https://api.typesafe.ai/v1/systemone` + - Protocol: HTTP/2 with persistent connection pooling and TLS session resumption. + - Authentication: Bearer token via `Authorization: Bearer `. + - Environment Fallback: `TYPESAFE_AI_API_KEY` is checked if the config field `apiKey` is empty. +- **Model Cost & Spend Cap:** + - Standard pricing model: **$0.042 per 1M input tokens**. + - Token estimation rule: 1 token $\approx$ 4 characters of JSON snapshot prompt. + - Spend Cap Default: `$1.00` per episode run. + - Hard Cap Behavior: When cumulative estimated spend reaches `spendCapUsd`, the system logs a `SpendCapExceededEvent` and transitions seamlessly to `MockProvider` (heuristic fallback) without throwing runtime exceptions or crashing Minecraft. +- **Confidence Calibration:** + - Default Confidence Threshold: `0.65`. + - Any decision returned with confidence $< 0.65$ triggers the fallback selector (selecting the highest confidence option that satisfies current immediate needs such as low health or urgent shelter). + +--- + +## 2. Multi-Threading & Concurrency Model + +- **Client Thread Protection:** + - Minecraft's main client render thread must never block on network I/O. + - All calls to `DecisionProvider.query()` run asynchronously in a dedicated cached executor thread pool. + - Target per-tick client overhead: $< 0.3 \text{ ms}$ average, with a hard budget of $< 2.0 \text{ ms}$ for worst-case spikes. +- **State & Decision Synchronization:** + - Synchronization between the main tick thread and the decision background thread is managed via non-blocking `AtomicReference` and `AtomicReference`. + - While a network query is in-flight (typically 70–500 ms), the bot continues executing its active Baritone goal or holds state. +- **Preemptive Reflex Engine:** + - Synchronous reflex evaluations execute every tick prior to accepting any Jev decision. + - If an emergency is detected (lava submersion, drowning/air $< 4$, burning without water, point-blank hostile damage, starvation $\le 2$ food), reflexes immediately seize control, execute protective actions (e.g. step back, swim up, eat food, sprint dodge), and cancel any obsolete asynchronous goal. + +--- + +## 3. Baritone Integration & Actuation + +- **API Boundary & Licensing:** + - Strictly binds to `baritone.api.BaritoneAPI` via public interfaces. + - Zero forking and zero bundling of Baritone source code, fully respecting the LGPL-3.0 license. + - Baritone is loaded as a runtime mod (`modCompileOnly` during build). +- **Legitimacy & Fair Mode:** + - `fairMode=true` by default: sets `BaritoneAPI.getSettings().legitMine.value = true`. The bot only pathfinds to and mines blocks that have been exposed to player sight or are logically discoverable without X-Ray cheats. + - `smoothLook=true` by default: activates cinematic camera interpolation so video recordings appear organic rather than jerky or robotic. + - `allowSprint=true`: enables tactical sprinting during pathfinding and combat flees. +- **Nether Pathfinding:** + - Includes `dev.babbaj:nether-pathfinder:1.6` runtime capability for dimension transitions. + +--- + +## 4. Safety, Watchdogs & Controls + +- **Singleplayer Restriction:** + - Automation bots on public servers violate multiplayer fair-play rules. + - `allowMultiplayer=false` is enforced by default. If the player connects to an external multiplayer server, the mod logs a warning and disables autonomous ticking unless the user explicitly overrides `allowMultiplayer: true` in `jevplayer.json`. +- **Instant Kill Switch:** + - Keybinding: `F9` (default MISC category). + - Pressing `F9` immediately sets the internal state to `DISABLED`, cancels all active Baritone processes (`getCustomGoalProcess().isActive()`, `getPathingBehavior().cancelEverything()`), and halts background polling. +- **Watchdog Escalation:** + - **Stuck Watchdog:** Triggers if player position has moved $< 1.5$ blocks over a 45-second sliding window while no inventory changes have occurred. Clears pathing cache, jumps/steps aside, and resets goal. + - **Loop Breaker:** Triggers if the same high-level action fails 3 consecutive times. Blacklists that specific action for 60 seconds to prevent getting trapped in local minima. + - **Death Watchdog:** Detects player death, records the milestone failure, awaits respawn, and resets the goal planner to Phase 1 (gather wood). + +--- + +## 5. Security & Privacy + +- **Zero API Key Leakage:** + - The API key is never serialized into plain text in `episode_events.json`, `decision_log.jsonl`, standard Minecraft logs, or rendered on the HUD overlay. + - The method `JevPlayerConfig.getRedactedApiKey()` masks all but the first 7 and last 4 characters (`sk-live_***abcd`). + - No secret keys are stored in version control; `.gitignore` guards all environment and secret files. + +--- + +## 6. HUD & Video Overlay + +- **In-Game Overlay:** + - Keybinding: `F8` toggles HUD display on/off. + - Visuals: Clean semi-transparent card rendering current milestone, active Jev action, decision confidence percentage, rolling latency (p50/p95), watchdog state, and cumulative token spend. + - Rendering Throttling: State text formatting is throttled to update at most once every 200 ms to prevent per-frame garbage generation. diff --git a/LICENSE b/LICENSE new file mode 100644 index 0000000..3aa05e8 --- /dev/null +++ b/LICENSE @@ -0,0 +1,21 @@ +MIT License + +Copyright (c) 2026 oiupoyt, TypeSafe AI + +Permission is hereby granted, free of charge, to any person obtaining a copy +of this software and associated documentation files (the "Software"), to deal +in the Software without restriction, including without limitation the rights +to use, copy, modify, merge, publish, distribute, sublicense, and/or sell +copies of the Software, and to permit persons to whom the Software is +furnished to do so, subject to the following conditions: + +The above copyright notice and this permission notice shall be included in all +copies or substantial portions of the Software. + +THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR +IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, +FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

Allocation Avoidance & Zero-GC Strategies + +Frequent garbage collection cycles on the client JVM cause perceptible micro-stuttering. JevPlayer incorporates strict allocation-minimization practices: + +### Reusable Buffers for Prompt Formatting +- Instead of creating short-lived `String` instances on every tick, `StateSnapshot` formats its state prompt into pre-allocated `StringBuilder` instances. +- Primitive fields (`float health`, `int food`, `int level`, `long timeOfDay`, `int coalCount`, etc.) are directly formatted without boxed object wrappers (`Integer`, `Float`). + +### Bounded Collections & Ring Buffers +- `ActionHistoryEntry` instances are stored in a fixed-size ring buffer (capacity 10). When new history arrives, the oldest entry is overwritten in-place without expanding or reallocating arrays. +- Legal actions use `EnumSet`, backed by a single 64-bit primitive long bitmask. Adding, removing, or checking legal actions requires zero memory allocations. + +### HUD Rendering Throttling +- Minecraft invokes HUD rendering callbacks on every frame (60 to 144+ times per second). +- String assembly and metric calculations are throttled to update at most once every `hudRefreshRateMs` (default: 200 ms). Between updates, the HUD simply renders the cached text components. + +### Non-Blocking HTTP Client +- All remote I/O is performed using Java's built-in `java.net.http.HttpClient` configured with: + - HTTP/2 multiplexing. + - Connection reuse and TLS session caching. + - A fixed daemon thread pool (`Executors.newSingleThreadExecutor(...)`). + +--- + +## 3. Profiling with Spark + +[Spark](https://spark.lucko.me/) is the standard profiler for modern Fabric environments. + +### Profiling the Client Thread +To profile JevPlayer's client-side tick footprint in-game: +```text +/spark profile --thread Client --timeout 60 +``` +When the 60-second profile concludes, inspect the call tree under: +- `net.minecraft.client.MinecraftClient.tick()` +- Look for `com.typesafe.jevplayer` packages. +- Ensure total sampling percentage for `com.typesafe.jevplayer` remains $< 0.5\%$ of client tick time. + +### Profiling Memory Allocation Rate +To identify any memory allocations generated by JevPlayer: +```text +/spark heap --alloc +``` +Filter classes for `com.typesafe.jevplayer`. Memory allocation rate should be $< 5 \text{ KB/sec}$ during steady-state autonomous play. + +--- + +## 4. Profiling with Java Flight Recorder (JFR) + +Java Flight Recorder is built directly into OpenJDK and provides low-overhead JVM diagnostics. + +### Launching with JFR Enabled +Add the following JVM argument in the Gradle `runClient` task or Minecraft launcher: +```bash +-XX:+UnlockDiagnosticVMOptions \ +-XX:+DebugNonSafepoints \ +-XX:StartFlightRecording=dumponexit=true,filename=jevplayer-profile.jfr,settings=profile +``` + +### Key Metrics to Validate in JDK Mission Control +1. **Garbage Collection Pauses:** + - Verify that young-gen GC pause times remain $< 5 \text{ ms}$. + - Confirm that old-gen full GCs do not occur during a 1-hour session. +2. **Thread Allocations:** + - Filter the "Allocation in new TLAB" and "Allocation outside TLAB" views by `com.typesafe.jevplayer`. + - Confirm that no tick-level allocation loops exist. +3. **Socket I/O:** + - Confirm that all `java.net.http` network activity is confined to the `jev-decision-worker` thread. + +--- + +## 5.

Launch singleplayer survival in mock mode: + ```json + { + "mockMode": true, + "confidenceThreshold": 0.65, + "fairMode": true + } + ``` +2. Enable HUD overlay (`F8`) and let the bot play undisturbed for 60 minutes (72,000 game ticks). +3. Verify the following exit criteria: + - **No Out-Of-Memory (OOM):** Heap usage remains flat with normal sawtooth GC reclamation. + - **No Deadlocks:** Worker threads terminate cleanly when leaving world. + - **Watchdog Stability:** If the bot gets stuck in terrain, watchdog recovers within 45 seconds without operator intervention. + - **Kill Switch:** Pressing `F9` immediately releases all Baritone controls and stops autonomous ticking. diff --git a/gradle.properties b/gradle.properties new file mode 100644 index 0000000..fe04f2d --- /dev/null +++ b/gradle.properties @@ -0,0 +1,16 @@ +org.gradle.jvmargs=-Xmx3G -Djdk.lang.Process.launchMechanism=FORK +org.gradle.parallel=true +org.gradle.java.home=/home/oiupoyt/.local/share/oneclient/metadata/java/zulu25.36.205-ca-jdk25.0.4.1-linux_x64/zulu25.36.205-ca-jdk25.0.4.1-linux_x64 +org.gradle.java.installations.paths=/home/oiupoyt/.local/share/oneclient/metadata/java/zulu21.52.203-ca-jdk21.0.12.1-linux_x64/zulu21.52.203-ca-jdk21.0.12.1-linux_x64 + +# Mod Properties +mod_version=1.0.0 +maven_group=com.typesafe.jevplayer +archives_base_name=jevplayer + +# Minecraft 1.21.11 +minecraft_version=1.21.11 +yarn_mappings=1.21.11+build.6 +loader_version=0.19.5 +fabric_version=0.141.6+1.21.11 +baritone_version=1.17.0 diff --git a/gradle/wrapper/gradle-wrapper.jar b/gradle/wrapper/gradle-wrapper.jar new file mode 100644 index 0000000..a4b76b9 Binary files /dev/null and b/gradle/wrapper/gradle-wrapper.jar differ diff --git a/gradle/wrapper/gradle-wrapper.properties b/gradle/wrapper/gradle-wrapper.properties new file mode 100644 index 0000000..c42672d --- /dev/null +++ b/gradle/wrapper/gradle-wrapper.properties @@ -0,0 +1,7 @@ +distributionBase=GRADLE_USER_HOME +distributionPath=wrapper/dists +distributionUrl=https\://services.gradle.org/distributions/gradle-9.7.1-bin.zip +networkTimeout=10000 +validateDistributionUrl=true +zipStoreBase=GRADLE_USER_HOME +zipStorePath=wrapper/dists diff --git a/gradlew b/gradlew new file mode 100755 index 0000000..f5feea6 --- /dev/null +++ b/gradlew @@ -0,0 +1,252 @@ +#!/bin/sh + +# +# Copyright © 2015-2021 the original authors. +# +# Licensed under the Apache License, Version 2.0 (the "License"); +# you may not use this file except in compliance with the License. +# You may obtain a copy of the License at +# +# https://www.apache.org/licenses/LICENSE-2.0 +# +# Unless required by applicable law or agreed to in writing, software +# distributed under the License is distributed on an "AS IS" BASIS, +# WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. +# See the License for the specific language governing permissions and +# limitations under the License. +# +# SPDX-License-Identifier: Apache-2.0 +# + +############################################################################## +# +# Gradle start up script for POSIX generated by Gradle. +# +# Important for running: +# +# (1) You need a POSIX-compliant shell to run this script.
