Branding. The reported "OpenAI Codex" was not a banner — the TUI banner has
said "Welcome to Code" all along. It was the model describing itself. Every
request carries BASE_INSTRUCTIONS, and `zen5-coder` matches none of the
OpenAI slug prefixes in find_family_for_model, so it lands on
derive_default_model_family -> core/prompt.md, whose first line read "You are
a coding agent running in the Codex CLI ... led by OpenAI". The agent was
told who it was, and it answered honestly.
Fixed the harness identity in all eight prompts (keeping each model's own
identity: "based on GPT-5" stays, the harness around it becomes Hanzo Dev),
the per-turn header, approval and model pickers, the login success page, MCP
tool titles and approval prompts on both client and server sides, seatbelt
policy header, cloud copy, two stale User-Agents, and the CLI hints that
named the wrong binary. Golden JSON fixtures moved with the code they assert.
Deliberately NOT changed, because they are wire and not text: `OPENAI_*` and
`CODEX_*` env vars, the `codex`/`codex-reply` MCP tool names and the
`code-mcp-server` server name (hosts key allowlists off them), `codex.*` OTEL
event names, the `openai` provider id, model slugs, `~/.code` on disk, and
the `https://api.openai.com/auth` JWT claim namespace.
Control. `cli/src/proto.rs` was a complete bidirectional control plane —
Submission JSON lines in, Event JSON lines out, the whole `Op` set including
QueueUserInput — exported from lib.rs with no subcommand to reach it. Wired
it up as `dev proto`. That is the difference between interrupting a turn and
steering one: `app-server`'s sendUserMessage hardcodes Op::UserInput, which
calls sess.abort() and restarts the turn.
$ printf '%s\n' '{"id":"s1","op":{"type":"interrupt"}}' \
'{"id":"s2","op":{"type":"shutdown"}}' | dev proto
{"id":"","event_seq":0,"msg":{"type":"session_configured",
"session_id":"4d82071e-...","model":"zen5-coder",...}}
{"id":"s2","event_seq":1,"msg":{"type":"shutdown_complete"}}
Also: upstream-merge.yml polled openai/codex every 30 minutes. That is the
wrong upstream (codex-rs reaches us through just-every) and a cron cannot
work against a disjoint history anyway — it needs a hand-supplied merge base.
Retargeted to just-every/code and made it manual, pointing at the procedure
in LLM.md. Purged @just-every/code from the release and recovery pipelines,
which would otherwise have published our binaries under their scope.

Our history is just-every's with author emails rewritten, so the graphs are
disjoint and git finds no merge base. Supplied one by hand: d1f1f51a41, the
just-every commit matching our Oct-2025 fork point (22 files apart). 9618
upstream commits, 7004 files, +1.81M/-159k, 37 conflicts.
Resolution:
- Upstream code where our side was the Oct-2025 prototype of a feature they
have since reimplemented 3-5x larger (agent_runs, browser_sessions,
history_cell/{agent,browser}, the vt100 harness and its snapshots).
- Upstream's config.rs module split (builder/defaults/sources/validation)
kept; zen5-coder and the provider-follows-model rule re-applied on top.
- Ours where the file IS the identity: README, package.json, postinstall,
release notes pipeline, integration-zed.
- Hybrid where upstream improved a file we had branded: updates.rs (their
release-repo migration, our hanzoai/dev), release.yml (their fail-fast npm
auth check, our package name), chatwidget.rs (their turn handling, our
HANZO_USER_KEY hint), exec human output (their 237 lines, our banner).
Superseded and dropped deliberately: our resume_command_name() coder-alias
hack — upstream's derive_resume_command_name() reads the invocation basename
generically, which yields "dev" for us.
LLM.md now records the real topology and the sync point; AGENTS.md and
CLAUDE.md are symlinks to it again. Single parent on purpose: adopting
jecode/main as a second parent would re-import 13,742 commits carrying the
upstream author emails a prior rewrite deliberately removed.
Version 0.2.188 -> 0.2.189.

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
See docs/migration/ for detailed migration status and roadmap.
