457 sites carried an upstream prefix into every surface a user reaches — shell
exports, docs, CI, the SDK. CODEX_ is not our name and it was never going to
stop arriving on its own: it is what upstream writes, and every sync brings more.
Two namespaces, because they answer different questions.
DEV_* the app's own configuration — DEV_HOME, DEV_PROFILE, the rest
HANZO_API_KEY a credential for the Hanzo stack, which is not app config
CODEX_API_KEY held the literal string "CODEX_API_KEY", so the rename moves the
value and not just the constant. It becomes HANZO_API_KEY, which is what
create_hanzo_provider already reads through HANZO_MACHINE_ENV_KEYS — one name
for one credential instead of two spellings of it.
vendor/ is untouched, which is the point of vendor/: upstream code keeps
upstream names, and the boundary is a path rather than a habit.
The docs read as OpenAI's Codex CLI: a getting-started page titled for it,
`codex --enable skills` and `code sandbox macos` for commands that do not
exist, defaults given as gpt-5.1-codex-max/openai when they are
zen5-coder/hanzo, a Homebrew page describing a formula we do not publish.
Removed three tui-stream-chunking notes and the execpolicy page: they
document modules and a subcommand that live only in the vendored upstream
copy. There is no execpolicy subcommand and no .codexpolicy loader in
code-rs; the page told users to run something the binary does not have.
Rewrote tui-alternate-screen against the source. It described an
auto/always/never enum and a --no-alt-screen flag; the shipped behavior is a
tui.alternate_screen bool with Ctrl+T, which replays the transcript into
scrollback on the way out — a better answer to Zellij than the one written
down. Genuine openai-provider documentation stays.
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 updates `codex exec` so that, by default, most of the agent's
activity is written to stderr so that only the final agent message is
written to stdout. This makes it easier to pipe `codex exec` into
another tool without extra filtering.
I introduced `#![deny(clippy::print_stdout)]` to help enforce this
change and renamed the `ts_println!()` macro to `ts_msg()` because (1)
it no longer calls `println!()` and (2), `ts_eprintln!()` seemed too
long of a name.
While here, this also adds `-o` as an alias for `--output-last-message`.
