 - 2026-05-25：Batch AF 未派发 Reasonix worker；基于 Batch AE Worker B 只读审计和 CodeGraph/`rg` 本地复核，主控完成 table overlay 小切片。
   - 修改：`editor_runtime/overlays.rs` 新增 `table_overlay_anchor_from_table`、`current_table_overlay_anchor`、`table_row_aux_style`、`table_col_aux_style`；`lib.rs` 删除同名实现并通过 import 继续调用。
   - 边界：未迁 table selection signal、row/column click handler、overlay DOM view 或 `table_selection_overlay_style`；本批只外置表格 overlay anchor / aux style 的纯 DOM rect 与 CSS 计算。
-  - 验证待补：`cargo fmt --manifest-path rust/Cargo.toml --all --check`、`cargo check --manifest-path rust/spikes/leptos-tiptap-spike/Cargo.toml`、wasm release build、`wasm-bindgen`、`task489`、`task488`、`task479`。
