 At reconciliation time the plugin scans workspace-sourced `user/message` events and derives the latest state for each visible scope. Successful nested touches aggregate under their parent execution token, including when a later composite result is blocked; the top-level result transfers them either to the open session step or directly to a per-agent projection queue. A `step/end` releases its staged touches only after that boundary is durable, and the next `agent/pre-step` waits for the serialized projections. Each projection composes against visible history plus the current inbox and replaces the single pending workspace context instead of accumulating intermediate renderings.
 
-An unchanged path and digest is suppressed. A logged removal is a tombstone, so a reappearing candidate becomes a new `set`. Resume works from persisted metadata: a compatible visible baseline supplies comparison state rather than causing another complete baseline to be appended. If compaction removes an instruction event from the visible surface, that state no longer suppresses a later load, matching the fact that the model can no longer see it. Only changes actually included under the byte budget enter metadata or pending state, so an omitted file remains eligible on a later touch.
+An unchanged path and digest is suppressed. A logged removal is a tombstone, so a reappearing candidate becomes a new `set`. Resume works from persisted metadata: a compatible visible baseline supplies comparison state rather than causing another complete baseline to be appended. If compaction removes an instruction event from the visible surface, that state no longer suppresses a later load, matching the fact that the model can no longer see it. A change enters metadata or pending state only when its file-specific section retains at least one content byte, or when the original content is genuinely empty. Partial truncation commits the full-content digest once any byte survives; zero-content truncation remains eligible on a later touch. A baseline may retain budget diagnostics with no committed changes. A dynamic batch with no committed change is withheld entirely and retried on a later touch. An omitted file remains eligible on a later touch.
 
 The initial baseline's typed changes are comparison state only while its event remains in the visible session surface. Resume retains a compatible baseline and reconciles current baseline and visible dynamic scopes, so changes made while the agent was offline append transitions before the first resumed request. When compaction shadows the baseline event, the next entering pre-step composes the complete current baseline and records it in the same request; a successful filesystem touch can instead re-add an unchanged baseline scope or append baseline edits or removals as dynamic messages. Neither path rewrites the original event. The in-memory scope marker and provider-version cache only select and accelerate probes, so neither can suppress context the model no longer sees.

 协调时，插件扫描带工作区来源的 `user/message` 事件，并派生每个可见作用域的最新状态。即使后续复合结果被拦截，成功的嵌套 touch 也会聚合到父级执行 token 下；顶层结果会将它们交给打开的会话步骤，或直接交给逐 agent 投影队列。`step/end` 只会在自身边界持久化后释放其暂存的 touch；下一次 `agent/pre-step` 会等待串行投影完成。每次投影都会根据可见历史和当前 inbox 进行组合，并替换唯一一条待处理工作区上下文，而不会累积中间渲染结果。
 
-路径和 digest 均未变化时会被抑制。日志中的移除操作是一条墓碑记录，因此重新出现的候选项会成为新的 `set`。恢复操作从持久化元数据继续工作：兼容的可见基线会提供比较状态，而不会导致再次追加完整基线。如果压缩从可见表面移除某条指令事件，该状态不再抑制后续加载，这与模型已经无法看见它的事实一致。只有真正纳入字节预算的变更才会进入元数据或待处理状态，因此被省略的文件在之后的触碰中仍有资格加载。

 只有当初始基线事件仍在可见会话表层中时，其类型化变更才用作比较状态。恢复会保留兼容的基线，并对账当前基线和可见的动态 scope，因此 agent 离线期间的变更会在第一次恢复请求前追加为转换。当压缩遮蔽基线事件时，下一次进入步骤的 pre-step 会组合完整的当前基线，并在同一请求中记录它；也可以改由一次成功的文件系统触碰重新添加未变化的基线 scope，或把基线编辑或移除操作追加为动态消息。两条路径都不会重写原始事件。内存中的 scope 标记和提供方版本 cache 只用于选择探测对象并加速探测，因此二者都不能抑制模型已无法看见的上下文。
