+- 现象：跳一跳地块使用六面 UV 贴图后，看起来像贴图位置贴歪，顶面显示侧面纹理，或者旧单张地块图被拉到立方体多个面上。
+- 原因：运行态以 `z` 作为立方体竖直高度和相机下压方向，但 Three.js `BoxGeometry` / `RoundedBoxGeometry` 的默认材质 group 顺序把 `+Y` 当 top；如果直接按 `right / left / top / bottom / front / back` 写材质，玩法逻辑的 `top` 会贴到侧面。旧作品没有完整 `faceAssets` 时，把单张旧贴图强行作为 3D 六面 fallback 也会被误认为 UV 贴歪。

+## 跳一跳 UV 图集切片要防贴边矩形 u32 中间溢出
+
+- 现象：跳一跳草稿在背景、返回按钮和地板图集 image2 都生成成功后，前端报“执行跳一跳共创操作失败”，Vite 代理日志出现 `socket hang up`，后端日志出现 `jump_hop_atlas_slicing.rs` 内 `attempt to subtract with overflow`。
+- 原因：blob gradient 切片的 histogram 最大不透明矩形在计算顶部坐标时写成 `by0 + ly - sh + 1`。当模型输出的 UV 面内容刚好贴到 cell 顶边，数学结果本应是 0，但 `u32` 会先执行中间步骤 `0 - 1` 并在 debug 运行时 panic。
+- 处理：顶部坐标先在局部坐标内用 `ly.saturating_add(1).saturating_sub(sh)` 计算，再加 block 偏移；不要恢复成连写减法。补充贴顶两行不透明矩形回归测试，保证贴边 UV 面不会打崩共创接口。
+- 验证：`RUSTC_WRAPPER= cargo test -p api-server --manifest-path server-rs/Cargo.toml jump_hop_atlas_slicing::tests::max_opaque_rect_handles_content_touching_top_edge`；整组再跑 `RUSTC_WRAPPER= cargo test -p api-server --manifest-path server-rs/Cargo.toml jump_hop`。

+## 跳一跳生图切图主路径不要绕过自适应图集切片
+
+- 现象：拉取 `fix/jump-hop-image-gen` 后，如果又把生成链路切回旧固定坐标裁切，容易和该分支解决的 AI 图集偏移、间距不均、UV 面位置漂移问题互相抵消，导致新生图链路的实际收益无法验证。
+- 原因：当前跳一跳 image2 prompt 仍要求 3x6 大单元和 4x3 UV 子网格，这是给模型和算法的结构约束；真实生产切图由自适应 `SeedRefinement + blob + gradient + max opaque rectangle` 链路消化 AI 输出偏差。固定网格切片只能验证理想图集，不适合覆盖新分支的主修复。
+- 处理：生产生成链路优先调用 `slice_tile_atlas_adaptive(...)`；旧固定 `slice_jump_hop_tile_atlas(...)` 只保留为对照测试、实验和必要 fallback 参考。若自适应切图出现具体误切，应优先修正自适应模块的边界检测、主 blob、透明/安全色处理和回归测试，而不是直接全局切回固定坐标。
+- 验证：新生成作品下载 `tile-01-top/front/right` 等面贴图时，单图应基本充满对应主题面内容，不应出现大块空背景、相邻面混入或纯色原型 cube；同时执行 `RUSTC_WRAPPER= cargo test -p api-server --manifest-path server-rs/Cargo.toml jump_hop_atlas_slicing -- --nocapture`。

 2. v1 不再单独生成角色图片，运行态固定使用抠除白底后的陶泥儿 logo 透明 PNG 作为玩家角色；

 待解决问题（风险程度：高）：跳一跳创作链路目前仍是一次 HTTP 请求内串行生成背景底图、返回按钮、地板贴图图集、切片和 OSS 写入；VectorEngine image2 单步 timeout/connect 失败会在后端最多重试 5 次，而前端只有 20 分钟总等待窗口。若某次背景底图生成接近或超过 18 分钟，前端会先报“请求超时，请稍后重试”，但后端可能继续跑完并在数分钟后写入草稿；同时因为背景、返回按钮和图集等中间资产未按阶段落库，同一 session 超时后重试会重新从背景图开始生成，存在重复生图、重复计费、用户误以为失败、作品架状态短时间不一致的风险。后续应将跳一跳生成改为后端任务化 / 可轮询真实阶段进度，并在每个素材阶段成功后写入可恢复状态；同时收口后端全局生成 deadline、前端等待策略和失败态回写，确保超时、重试和最终成功不会互相打架。
 
 生成页“当前跳一跳信息”只展示实际参与创作提示词的主题、地块提示词等用户可理解信息；`stylePreset` 等未参与当前 image2 提示词组装的内部风格枚举不得作为兜底内容展示，避免把 `minimal-blocks`、`paper-toy` 等工程值暴露给创作者。
 
+运行态地块刷新规则固定由后端路径快照决定：后续地块只会出现在当前地块正负 45 度方向，当前版本已有的最远相邻地块间距作为各难度 `max_gap`，每次新地块距离按 seed 在 `max_gap * 55%` 到 `max_gap` 之间随机，距离不允许为 0。前端可见窗口不得再把目标块强制放到固定屏幕坐标，而必须按服务端真实相邻距离缩放投影；最大距离沿用当前固定视觉间距，较近距离沿同一 45 度方向靠近当前块。

-跳一跳当前长按蓄力手感统一采用 `chargeToDistanceRatio=0.004`，用于把长按时长换算成世界跳跃距离；如果历史路径仍保存其它系数，`start_run` 会在开局归一化到新系数。用户按住画面开始蓄力，松手立即起跳；前端必须提交 `dragDistance` 以及换算到后端世界坐标的 `dragVectorX/dragVectorY`，后端正式裁决用该方向向量计算真实落点，只有旧客户端缺失方向、方向非有限数或向量长度过小时，才 fallback 到当前地块中心指向下一块地块中心。成功判定使用下一块地块可见顶面 footprint：后端以该地块 `width/height` 的收缩矩形模拟 45° 视角下的可见顶面，当前命中区约为宽度 72% 和高度 52%，落点进入该视觉顶面则成功，未进入则失败；旧 `landingRadius/perfectRadius` 只保留兼容读写，不再作为当前命中真相。蓄力中角色只做垂直压缩，不沿目标方向拉伸；蓄力反馈可显示朝向当前目标方向的轻量引导，但不显示落点辅助点、投影圈或其它命中提示。松手后运行态必须立即生成 `visualJump`，用当前角色位置作为起点、前端预测真实落点作为终点，播放约 `560ms` 的角色飞行动画：视觉预测必须使用当前显示窗口的 current/next 地块作为方向来源，即使后端最新 run 已提前返回，也不能拿新 run 目标配旧窗口角色导致下一跳反向；角色沿本次提交方向弹向预测真实落点，成功也不得强制吸附回目标地块中心。若后端新 run 晚于飞行动画返回，角色必须停在预测真实落点等待；新 run 到达后应优先用 `lastJump.landedX/landedY` 映射出的真实落点显示角色，再把显示态切到后端最新 run，并用约 `1440ms` 的相机层推进过渡承接新窗口，避免先飞过很远再瞬间拉回地块造成闪现。推进时地块 DOM 层和 DOM 角色层统一包在同一个 camera layer 下移动，旧当前地块只随相机推进保留在屏幕后方，不单独执行向上 / 向下飞走动画；玩家继续向前跳时，旧地块继续被新的相机推进带离视口，超过离屏阈值后自然销毁，新预览地块从上方露出，禁止用 p1/p2 各自 `top/left` 过渡造成角色和地块不同步。相机层推进必须同时使用 X/Y 偏移，从旧真实落点位置斜向滑到新当前地块聚焦位置，不得先横向瞬切到居中再纵向滑动。地块允许保留当前 / 目标 / 预览的深度尺寸差异，但该差异必须通过固定基准宽高上的 `transform: scale(...)` 缓动呈现，并与相机推进使用同一 `1440ms` 节奏；不要直接修改宽高造成瞬切，也不要再给当前态额外叠 CSS scale。相机推进期间角色自身必须禁用 `left/top` transition，只允许父级 camera layer 负责位移，否则角色局部坐标切换和相机推进会叠加，表现为落地后又从屏幕外闪回。
