Next review available in: 45 minutes You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository. How can I continue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

89-94: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win策略不匹配时迁移会永久暂停，日志未说明恢复方法。
如果上一次运行以
match中断，用户随后把legacyModelModeMigration改为default，第 89-94 行每次启动都只输出 warn 并返回。迁移不会继续，也不会按新策略重新开始。用户无法从日志得知需要把配置改回原策略，或删除chatluna_meta中键为conversation_model_mode_migration的记录。建议在 warn 文本中给出这两个恢复动作。

? 需要 500 行吗这个修复 |
确实有点多 我看看有没有能缩的地方 |

主要是迁移旧对话部分 conversation_model_mode.ts 这个比较大 不好弄 |

不迁移就行了，

The trigger condition required resolved.constraint.autoUpdateModel === true, but autoUpdateModel defaulted to undefined when no rule was configured, so the global autoUpdateConversationModel switch never took effect. Default it to true so the global switch works; rule autoUpdateModel/fixedModel can still opt out per-route. Refs #1012
use.model <model> now writes rule autoUpdateModel: false so the manually picked model is not overwritten by the global autoUpdateConversationModel switch; use.model -a restores following and switches to the default model. No modelMode field needed - route-level rule controls the behavior. Refs #1012

弄了一下现在修复代码不到 100 lines，差不多了测试没问题就行 |
|
我设想的是用会话作为一个单位 例如一个路由下 会话A是fixed 会话B是default C是null 那么会话B会自动更新 |
|
现在是会话下模型只要不固定的都会自动更新，对齐 1.3 之前的那个全局自动更新 |

- use.model now writes autoUpdateModel to the target conversation's managed constraint via bindingKey instead of the current session, so cross-binding operations affect the right route. - auto mode skips writing model when pickModel returns null, matching applyAutoModelUpdate's no-op behavior instead of persisting null.

updateManagedConstraintByBindingKey kept the caller session's platform and selfId while the constraint name was built from the target bindingKey, persisting records whose scope metadata mismatched their name. Parse platform/selfId from the bindingKey so the constraint matches the target route. Refs #1012
- chatluna.chat without text now returns a message_required hint instead of koishi's generic missing-argument error. - chatluna.model.test without a model falls back to the global defaultModel; if neither is set, show a model_required hint. Refs #1012

model?.trim() ?? config.defaultModel.trim() distinguishes an omitted
argument (undefined -> default) from an explicitly empty/whitespace
argument ('' -> model_required), instead of || which silently fell back
for empty input too.
