🔍 回归审计 + 总线系统 / Regression Audit + Bus System

• 回归审计 / Regression audit：对 1915202 起的改动做全量业务逻辑审计（6 路并行 + 对抗验证），修复雷达红石输出失效、传感器子关卡姿态误用、flipflop 同步风暴、子图状态泄漏、Sable 专用服务器反射错误等。/ Full business-logic audit of changes since 1915202 (6 parallel + adversarial verification): fixed radar redstone output, sensor sub-level pose misuse, flipflop sync storm, sub-graph state leak, and Sable dedicated-server reflection errors.
• 总线跨方块编辑修复 / BUS cross-block editing fixes：创建同名 BUS_OUT 不再自动同步覆盖原频道 owner 的 band 定义；改名保留自身 band 与连线（BUS_IN 采用新频道 band）；点击空白处提交频道名；修复反复编译+运行导致 BUS_IN 读 0（loadGraphFromBytes 的 generation 冲突）；自身 BUS_OUT 不再误报冲突。/ Creating a same-name BUS_OUT no longer overwrites the original owner's band definitions; rename preserves the node's bands and connections (BUS_IN adopts the new channel's bands); clicking empty space commits the channel name; fixed BUS_IN reading 0 after repeated compile+run (generation conflict in loadGraphFromBytes); a node's own BUS_OUT no longer reports a false conflict.
• 编译 BUS 断线修复 / Compile-time BUS disconnection fix：移除 loadGraphFromBytes 中 cleanupBusChannels()，防止编译时向客户端广播空频段导致连线永久丢失。/ Removed cleanupBusChannels() from loadGraphFromBytes to stop empty band syncs from permanently deleting connections.
• 编辑器冲突检测 / Editor conflict detection：修复 crossConflict 死代码（客户端从不显示跨方块冲突），改名/删除时 localBusNames 保持同步。/ Fixed the crossConflict dead code (cross-block conflicts were never shown client-side); localBusNames stays in sync on rename/delete.

📦 封装节点 / Encapsulation Nodes

• 封装节点输出假数值 / Fake outputs from encapsulated nodes：修复 recompileEvaluatorFull() 的 runtimeState.clear() 清除子图时序组件状态（DELAY/LATCH/flipflop 等），导致封装内部计算偏差。1.2.3 的子评估器缓存掩盖了此问题，修复缓存失效后暴露。现在重编译前保存并恢复 subStates。/ runtimeState.clear() no longer wipes sub-graph sequential state (DELAY/LATCH/flipflop etc.) — subStates are saved and restored before a full recompile; previously masked by the v1.2.3 sub-evaluator cache.
• 封装内时序节点编辑区状态 / In-encapsulation sequential node state：扩展 RuntimeStateSyncPacket 携带子图 flipflop 状态，编辑器在子图内显示正确的时序节点实时状态。/ RuntimeStateSyncPacket now carries sub-graph flipflop state so the editor shows correct live sequential state inside encapsulation.
• 子图展开状态初始化 / Sub-graph expansion state init：修复进出封装节点后 expandedInitDone 未重置，导致子图展开节点不恢复。/ Fixed expandedInitDone not resetting when entering/leaving encapsulation, so expanded sub-graph nodes fail to restore.

📝 公式编辑器 / Formula Editor

• 公式节点双缓存统一 / Unified formula cache：移除 GraphEvaluator.scriptCache，改为 node.cachedScript 单一真相源，消除引脚解析与求值的缓存漂移。/ Removed GraphEvaluator.scriptCache; node.cachedScript is now the single source of truth, eliminating pin-resolution vs. evaluation cache drift.
• 公式节点清空回弹 A+B / Formula empty-value bounce-back A+B：createEditState 不再强制默认值。/ createEditState no longer forces default values.
• 公式编辑器光标与选区 / Formula editor caret & selection：MLE 图空间坐标转换 + 方向键折叠选区。/ MLE graph-space coordinate conversion + arrow-key selection folding.
• V3→V4 迁移 / V3→V4 migration：GraphMigration 复用 GraphNode.inputPinId/outputPinId，支持旧版动态引脚连线保留。/ Migration reuses GraphNode.inputPinId/outputPinId so legacy dynamic-pin connections are preserved.

🔄 Sable 兼容 / Sable Compat

• Sable 兼容层加固 / Compat layer hardening：反射访问改编译期桥，专用服务器不再触发 ClientLevel 加载错误；雷达 Sable 结构扫描在专用服务器正常；无 Sable 环境安全回退。/ Reflection access replaced with a compile-time bridge — dedicated servers no longer trigger ClientLevel load errors; radar Sable structure scanning works on dedicated servers; safe fallback without Sable.
• Sable 重连 / Sable reconnection：sable$getLoadingDependencies 通过 getPlot(chunkPos) 安全返回子世界引用，修复重进存档后 Sable 节点失效。/ Safe sub-level reference via getPlot(chunkPos) — Sable nodes survive world reload.

🛠️ 其他修复 / Other Fixes

• 雷达锁定 / Radar lock：空中 blip 锁定不再被方块 UI 拦截；移除编辑会话成员校验（锁定是使用操作）。/ Air-blip lock is no longer intercepted by the block-UI; removed the edit-session membership check (locking is a use operation).
• 数值输入回弹 / Numeric input bounce-back：编辑器打开时跳过 NBT 全量图替换，防止服务端同步覆盖本地编辑值。/ Skipped full-graph NBT replacement on editor open so server sync cannot overwrite local edits.
• 临时视角跨方块污染 / Temp camera-view contamination：改为按 BlockPos 存储。/ Temp camera view is now stored per BlockPos.
• 中途加入玩家获取完整图 / Mid-game joiners get the full graph：loadAdditional 守卫由 graphReady 锁存改为本地待 ACK 编辑计数（pendingLocalOps）—— 加入者无本地编辑时总是应用服务端权威图；活跃编辑者仍受回弹保护（仅在发送 op 且未 ACK 期间跳过替换）。/ The loadAdditional guard now uses a pending-local-op counter instead of the graphReady latch — joiners with no local edits always apply the authoritative graph, while active editors keep bounce-back protection (replacement skipped only while ops are un-ACKed).

👥 Multiplayer Collaboration / 多人协作

All 7 blocks now support real-time collaborative graph editing — multiple players can edit the same node graph simultaneously. / 全部 7 种方块支持多人实时协作编辑同一节点图。

⚡ Architecture Refactoring / 架构重构

🔧 Debug Toolchain / 调试工具链

📌 View Bookmarks / 视角书签

• ★ button (bottom-right, above ▼) toggles bookmark panel / ★按钮开关书签面板
• [+] / Ctrl+M save current view, [↺] / Home reset to origin
• [✎] rename, [✕] delete, [→] or click name to jump with 200ms ease-in-out transition
• Drag name area to reorder, synced via MOVE_BOOKMARK op
• Click outside naming dialog to cancel; Esc handled by unified popup stack
• Multiplayer-synced via ADD_BOOKMARK / REMOVE_BOOKMARK / RENAME_BOOKMARK / MOVE_BOOKMARK ops

🐛 Fixes & Polish / 修复与打磨

• 🔧 Graph Init — onLoad() bumps generation to force full recompile on first tick.
• 🚌 BUS Channel — registerChannels() no longer requires bandCount()>0; empty-band channels register so BUS_IN reads immediately.
• 🎨 Color Picker UX — ESC closes picker + panels together. Duplicated nodes get sortB = original+1.
• 📝 Bilingual Comments — All graph/, blocks/, network/ source comments now Chinese+English.
• 🐛 Encapsulation DEBUG Visibility — EvalSnapshot now captures sub-evaluator outputs + debugTimes. Signal Generator (blue X marker) and Signal Probe work correctly inside encapsulation sub-graphs. / 封装内信号发生器（蓝色X标记线）和探针现在正确显示。
• ⌨️ Esc Key Delegation — Esc now closes sub-UI (bookmark rename, export/import dialog, color picker) before closing the entire editor screen. / Esc 先关闭子 UI 再关整个编辑界面。
• 🔒 Soft-Lock Scope — Node locking now scoped by ownerNodeId. Selecting a node inside encapsulation no longer falsely locks main-graph nodes with the same ID. / 封装内选中节点不再误锁主图同 ID 节点。
• 🖱️ Cursor Scope Isolation — Remote player cursors are now filtered by scope; cursors inside encapsulation are hidden from main-graph view and vice versa. / 远端光标按作用域隔离。
• 🟡 ENCAPSULATION Occupant Highlight — Golden border + player name label on ENCAPSULATION nodes in the main graph when other players are editing inside. / 主图中被占用的封装节点显示金色边框+玩家名。
• 📝 ENCAP I/O Rename Sync — Renaming ENCAP_INPUT / ENCAP_OUTPUT now sends SET_DISPLAY_TEXT op for server sync + undo support. / 封装I/O改名现在同步到服务端并支持撤销。
• 📋 Ctrl+D Copy Fix — Copy now uses server-authoritative ID allocation (ADD_NODE_REQUEST → ACK); data ops are deferred until all real IDs assigned. Sub-graph content recursively synced for ENCAPSULATION nodes. Fixes "empty node on other clients". / 复制走服务端权威ID分配，封装子图递归同步。
• 📐 Manual Curve Fixed Y-Axis — Signal Generator manual curve mode now uses fixed Y range [-1.1, 1.1]; auto-scaling retained for formula mode. Control points clamped to visible range and rendered above border. / 手动曲线Y轴固定，控制点钳制+边框上方渲染。

🔗 Stable PinId Refactoring / 稳定引脚ID重构

Connections now bind to stable string pin identifiers instead of positional integer indices. Pin insertion, deletion, or reordering no longer breaks existing connections — they follow the pin by name.

Key changes:

• NodeConnection gains fromPinId / toPinId fields; save() / load() backward-compatible
• GraphNode adds inputPinIndex(id) / outputPinIndex(id) / inputPinId(i) / outputPinId(i) — pinId↔index resolution per node type
• NodeGraph.rebuildInputCache() resolves all pinIds to current indices, prunes stale connections
• GraphMigration V3→V4: one-time NBT upgrade converting integer pins to stable pinIds for FORMULA, ENCAP, BUS, and generic nodes (recursive into sub-graphs)
• GraphEvaluator BUS evaluation and ENCAP pin injection now match by pinId rather than cache position
• BusChannelHelper.syncBandsFromServer only disconnects actually-removed bands (by name), preserving reordered bands
• NbtVersions.DATA_VERSION bumped 3→4
• Eliminates ~200 lines of REWIRE/reconnect complexity from the v1.2.5 roadmap — pin reordering is now free

🧠 Relay Nodes / 继电器节点

Two new logic nodes for conditional signal routing — available in both Blueprint and Program Computers.

Both use the standard >0.5 threshold consistent with BOOL/GATE/OR. No parameters, pure combinatorial logic — compatible with multiplayer collaboration and encapsulation out of the box.

🪑 Sable Sub-Level Control Seat Camera / Sable 子关卡控制座椅相机

Two camera modes for Control Seat riders inside Sable rotating structures. Camera orientation computed client-side from block FACING + Sable render-pose quaternion — bypasses entity yaw sync (unreliable for retain_in_sub_level entities). Sable 旋转结构上控制座椅的两种相机模式。座椅世界朝向由客户端根据方块 FACING + Sable 渲染姿态四元数实时计算，不依赖 entity yaw 同步。

• ControlSeatBlockEntitySable: fixed missing setYRot() — entity yaw now properly updates both yRot and yRotO. / 修复缺失的 setYRot()。
• ControlSeatEntity: manual setPos skipped inside sub-levels (Sable handles positioning). / 子关卡内跳过手动 setPos。
• ControlSeatCameraMixin: registered in required:false sable mixin config — silently skipped without Sable. / 无 Sable 时静默跳过。

🎮 MOUSE_JOYSTICK Absolute Mode / 鼠标摇杆绝对值模式

Per-node toggle in the edit panel switches between incremental (direct mouse delta, default) and absolute (accumulated stick position with memory, clamped to [-1,1]). 编辑区提供每节点独立开关，在增量（默认，鼠标位移即输出）和绝对值（累积摇杆位置，停手保持）之间切换。

• Uses TOGGLE_BOOL op pipeline — server-authoritative, undo-supported, multiplayer-synced. / 复用 BOOL 开关流水线。
• Absolute accumulation uses ABS_SCALE=1/6 per tick for smooth control. / 绝对值每 tick 累积系数 1/6。
• Stick position persists across GUI open/close. / 开菜单再关闭位置保持。
• Both x and y axes accumulate independently. / X/Y 轴独立累积。

🔧 Signal Generator Auto-Scale Fix / 信号发生器自动缩放修复

• Root cause: computeVisibleRange() used fixed ±5 clipping, squashing large-range formulas (e.g. x*360) into a ~6-unit Y window while rendering used raw values → curve painted to chart corners looking like an inverse-proportional function.
• Fix: Replaced ±5 hard clipping with percentile-based robust range (p1–p99). Only extreme outliers (|v| ≥ 1e6) and NaN/Inf are filtered. Both DEBUG_SIGNAL_GEN and DEBUG_PROBE charts use the same logic.
• Y-axis range label: Chart top-right now shows min … max (e.g. 0.0 … 360.0) so the scale is immediately visible.
• Cache: Formula compilation cache (debugFormulaRpn) properly invalidated on formula edits — chart refreshes instantly.

🎨 Formula Editor UX / 公式编辑器体验

Syntax Highlighting / 语法高亮 — Real-time token-based colouring with 9 categories: functions (yellow), constants (pink), identifiers (cyan), numbers (orange), operators/parens (grey), comments (green), @output/assignment (purple), unknown (red underline). Token cache avoids per-frame re-parsing. / 实时词法彩色标注，9 种分类：函数（黄）、常量（粉）、标识符（青）、数字（橙）、运算符/括号（灰）、注释（绿）、@output/赋值（紫）、未知（红色下划线）。Token 缓存避免每帧重复解析。

Autocomplete Popup / 自动补全候选框 — Type identifier characters to trigger filtered dropdown (functions, named constants, current variables); type @ for immediate @output. Keyboard: ↑↓ navigate, Tab/Enter accept, Esc dismiss. Mouse: click any candidate to accept. Popup renders above all pins (z-layer C=5.5) with zoom-aware scaling — text and layout scale proportionally with graph zoom. Deleted variables immediately disappear from suggestions. / 输入标识符触发过滤候选框；输入 @ 立即建议 @output。键盘导航/接受/关闭，点击候选项接受。候选框渲染在所有引脚上方（C=5.5 层），支持缩放感知。删除变量立即从候选消失。

Real-Time Validation / 实时校验 — Red ⚠ badge on FORMULA node title bar; hover for tooltip list. Checks: bracket matching, unknown function, wrong arity, invalid assignment (errors), duplicate outputs, @output without identifier (warnings). Red border on the edit box when errors present. Validation cached after NBT reload to avoid per-frame re-parse. / 红色 ⚠ 徽章 + 悬停工具提示。校验：括号匹配、未知函数、参数数错误、无效赋值（错误），重复输出名、@output 缺变量（警告）。输入框红色边框。NBT 重载后缓存避免每帧重解析。

Named Constants / 命名常量 — (PI) and (E) in grouping parentheses are literal constants (π / e). Bare PI/E or inside function calls like sin(PI) are variable references (create input pins). Consistent across extractVariables(), compile(), and tokenize(). / (PI)/(E) 在分组括号内为字面常量。裸 PI/E 或函数调用内 sin(PI) 视为变量。三种解析入口行为一致。

Robustness / 健壮性 — Mouse drag selection restored (hlPos sync scoped). SET_FORMULA self-skip prevents EditState recreation → no focus loss during typing. Formula responder re-fetches graph node each keystroke (handles NBT sync between keystrokes). Connection cleanup corrected to use inputs()/outputs() clamps. Screen-width hardcoded 1920 replaced with getGuiScaledWidth(). Null safety in suggestion filtering. / 拖拽选区修复、SET_FORMULA 自跳、按键间图引用重获取、连线清理用 clamp 值、屏幕宽度动态获取、候选过滤 null 防护。

Tests / 测试 — 27 new unit tests covering tokenize, extractVariables, compile/evaluate, validate, parseScript, countFunctionArgs, and edge cases. / 27 个新单元测试。
