-# Task 04 Plan: Auto‑Mount Entire Repo & Auto‑CD
-
-> *This task is specific to codex-rs.*
-
-## Status
-
-**General Status**: Not started  
-**Summary**: Planning phase; missing Implementation details (How it was implemented and How it works).
-
-We’ll break Task 04 into discrete subtasks so we can implement, review, and test each part in isolation:
-
-## Subtasks
-
-### 04.1 – Config → `ConfigToml` + `Config`
-- Add `auto_mount_repo: bool` and `mount_prefix: String` to `ConfigToml` (with proper `#[serde(default)]` and defaults).
-- Wire these fields through to the `Config` struct.
-
-### 04.2 – Git root detection + relative‐path
-- Implement a helper in `codex_core::util` to locate the Git repository root given a starting `cwd`.
-- Compute the sub‐directory path relative to the repo root.
-
-### 04.3 – Bind‑mount logic
-- In the sandbox startup path (`apply_sandbox_policy_to_current_thread` or a new wrapper before it), if `auto_mount_repo` is set:
-  - Bind‑mount `repo_root` → `mount_prefix` (e.g. `/workspace`).
-  - Create target directory if missing.
-
-### 04.4 – Automate `cwd` → new mount
-- After mounting, update the process‐wide `cwd` to `mount_prefix/relative_path` so all subsequent file ops occur under the mount.
-
-### 04.5 – Config docs & tests
-- Update `config.md` to document `auto_mount_repo` and `mount_prefix` under the top‐level config.
-- Add unit tests for the Git‐root helper and default values.
-
-### 04.6 – E2E manual verification
-- Manually verify launching with `auto_mount_repo = true` in a nested subfolder:
-  - TTY prompt shows sandboxed cwd under `/workspace/<subdir>`.
-  - Commands executed by Codex see the mount.
-
-## Next steps
-Please review the plan above. If it looks good, I’ll implement the subtasks in order.
