CLI: resume/fork on WSL can restore lowercased cwd from SQLite-normalized path

What version of Codex CLI is running?

0.107.0

What subscription do you have?

Pro

Which model were you using?

gpt-5.3-codex

What platform is your computer?

Linux (WSL2), workspace under /mnt/c/...

What terminal emulator and version are you using (if applicable)?

Windows Terminal + WSL2 shell (bash/zsh)

What issue are you seeing?

resume / fork now restores a lowercased working directory on WSL mounts (for example /mnt/c/users/name/project), even when the original path casing was /mnt/c/Users/Name/Project.

That lowercased restored cwd can break downstream behavior that is case-sensitive at the string layer (for example trust/workspace config checks and unified exec command/tooling integrations that expect canonical Windows-style casing).

This looks like a regression from the change to read cwd from SQLite metadata first during resume/fork. SQLite stores a normalized cwd (including WSL lowercasing), and that normalized value is now reused as the actual fallback cwd, not just for comparison.

Related prior fix: #7995 (case-insensitive matching on WSL). This report is about a new side effect: normalized lowercase path being used as the resumed execution cwd.

What steps can reproduce the bug?

1. In WSL, open a repo from a mixed-case Windows-mounted path, for example:

• cd /mnt/c/Users/Name/Project

1. Start a session and do at least one turn so session metadata is persisted.
2. Exit Codex.
3. Resume or fork that session (codex resume or codex fork) with SQLite enabled (default path).
4. Inspect environment context / cwd used by the resumed session.

Observed: cwd can become a lowercased variant from normalized SQLite metadata (for example /mnt/c/users/name/project) instead of preserving original casing.

What is the expected behavior?

Resume/fork should preserve the original/usable cwd casing for execution context.

Path normalization should be used for equality/comparison only, not as the execution cwd that gets restored.

Additional information

Likely regression commit:
- c1afb8815af63c59b67824a73750884aa1a2e363 (tui: use thread_id for resume/fork cwd resolution) by @charley-oai

Relevant code points:

• codex-rs/tui/src/lib.rs (read_session_cwd, resolve_cwd_for_resume_or_fork)
• codex-rs/core/src/state_db.rs (normalize_cwd_for_state_db)
• codex-rs/core/src/path_utils.rs (normalize_for_path_comparison, WSL /mnt/<drive> lowercasing)

Potential fix direction:

• Keep normalized cwd in SQLite for matching/indexing,
• but preserve/store an execution-display cwd separately (or reconstruct from rollout) for resume/fork fallback cwd selection.
