Add `mid_turn` to assistant history records and cells, and retroactively mark previous Answer streams as mid‑turn when a new Answer id arrives so only the final output gets gutter/bold styling.
Also upgrade legacy `gpt-5-codex` slugs to `gpt-5.1-codex`, bump GPT‑5 profile/review defaults to `gpt-5.2`, and refresh related TUI snapshots.
This commit completes Phase 1 of the codebase cleanup plan documented in
ROADMAP.md and related migration documents.
Major changes:
- Removed legacy test suites from code-rs/ crates (~35,000 lines)
- Adopted upstream codex-mcp-client and codex-responses-api-proxy
- Deleted TUI compat layer, agent task planning docs, and orphaned modules
- Updated documentation to reflect current state and future phases
Test Coverage:
- Deleted tests from: app-server, apply-patch, chatgpt, cli, core, exec,
login, mcp-server
- Documented 9 remaining coverage gaps requiring new tests (see
docs/migration/legacy-tests-retirement.md)
- Preserved smoke test infrastructure in tui/tests/ui_smoke.rs
Crate Adoptions:
- mcp-client: Now re-exports codex-mcp-client with fork-specific buffer config
- responses-api-proxy: Now re-exports codex-responses-api-proxy with minimal
wrapper
- mcp-types: Updated to use upstream types where possible
TUI Cleanup:
- Removed compat.rs ratatui adapter layer
- Deleted obsolete modules: app_backtrack, custom_terminal, scroll_view,
text_block, transcript_app
- Archived agent_tasks/ planning docs to docs/archive/
Documentation Updates:
- ROADMAP.md: Marked Phases 1-2 complete, updated next actions
- TEST_SUITE_RESET.md: Documented Phase 1 completion
- DEAD_CODE_INVENTORY.md: Updated with deletion outcomes
- Added docs/migration/legacy-tests-retirement.md with 6-week plan
- Added docs/maintenance/prompt-architecture.md
Next Steps (Phase 2-3):
- Port critical test coverage (9 test files identified)
- Expand smoke test scenarios
- Continue upstream tracking per monthly cadence
