Summary

Codex v0.133.0 (PR #22709) trimmed unused fields from the TurnContextItem session structure. The turn_context JSONL payload now carries only model; fields like cwd and effort may be absent in sessions from v0.133.0+.

The parser already handled this correctly — all fields are extracted via optional .get().and_then() chains in handle_turn_context, so missing fields silently produce None without panicking. turn.rs also already had targeted tests for pre- and post-v0.133.0 payloads (turn_context_with_extra_legacy_fields_does_not_panic, turn_context_with_missing_trimmed_fields_does_not_panic).

What was missing was a set of version-specific regression tests in entry.rs and session.rs to document the v0.133.0 change and provide coverage at the full-session parse level.

Changes

src-tauri/src/parser/entry.rs

• v0133_turn_context_trimmed_payload_parses_as_turn_context_entry — verifies a minimal v0.133.0 turn_context (only model present) is parsed as turn_context entry type without panic
• v0133_all_standard_entry_types_parse_correctly — regression guard ensuring all four standard JSONL entry types (session_meta, event_msg, response_item, turn_context) parse correctly under v0.133.0 with the trimmed payload

src-tauri/src/parser/session.rs

• v0133_turn_context_trimmed_fields_session_parses_correctly — full session parse with a v0.133.0 turn_context (only model); verifies model is extracted, reasoning_effort is None, and the session parses without panic

Testing

All 134 Rust tests pass. All 128 frontend tests pass. Clippy and cargo fmt clean.
