## Why `codex-rs/tui/src/history_cell.rs` had become the dumping ground for transcript rendering: the shared trait, common helpers, and the concrete cells for messages, plans, MCP/search, notices, patches, approvals, session chrome, and separators all lived together. That made small transcript changes require reopening a very large file and made ownership less obvious. ## What changed - Replaced the monolithic `history_cell.rs` with a `history_cell/` module tree organized by concern. - Kept the existing `crate::history_cell::*` surface stable through re-exports in `history_cell/mod.rs`. - Moved the existing render coverage into `history_cell/tests.rs`. ## Reviewer notes - This PR is intentionally mechanical in mature — existing code and tests moving into files that match their concern. - The snapshot files under `codex-rs/tui/src/history_cell/snapshots/` moved with the extracted test module. `insta` resolves these unnamed snapshots relative to the source file that declares them, so this is path churn only; snapshot contents were not updated. - The small non-mechanical seam edits are limited to split fallout: sibling-module visibility for shared cell containers, moving approval-specific exec-snippet helpers beside approvals, fixing the separator module path, and keeping a couple of existing test helpers reachable after extraction.
