@hanzo/dev's latest is 0.6.91, published 2026-04-01. Every release run
since has ended red without publishing, for two independent reasons.
1. actions/upload-artifact@v3. The pin carries a comment about
git.hanzo.ai presenting as GHES, where v4 raises
GHESNotSupportedError — true, but this file lives under
.github/workflows/ and therefore runs on github.com, which now
hard-fails v3 during "Set up job":
This request has been automatically failed because it uses a
deprecated version of `actions/upload-artifact: v3`.
Not one step executed. Two hosts, opposite requirements, one file:
v3 belongs only under .hanzo/workflows/. Both uploads and the
download move to v4.
2. Default fail-fast. The aarch64 leg reached the deprecation check
first and died in 4s, cancelling the other four targets, so
`release` was skipped entirely. A run that read as one broken
architecture actually shipped zero. fail-fast: false.
And the packaging loop `continue`s past any artifact it does not
recognise, so a missing target would have quietly produced four npm
packages while @hanzo/dev still named five in optionalDependencies —
users on the fifth arch installing a wrapper with no binary under it.
A new step names the five and refuses before packaging.
Also the nine workspace tests that had preflight red, both stale
against the rename to `dev`:
- bash_completion_uses_code_command_name asserted the literal `_code`,
a second copy of the product name that went stale the moment
CLI_COMMAND_NAME became "dev". Derive the expectation from the
constant so it cannot drift again.
- The seven VT100 snapshots recorded a status header that now includes
`Directory: <cwd>`, resolved from std::env::current_dir() — the
checkout path of whoever ran the test. Those snapshots only ever
matched one machine. The harness now pins cwd to /snapshot: absolute
so it is taken verbatim, outside $HOME so it is never abbreviated to
~/…, and outside any git repo so no Branch: segment appears.
Every architecture stays in the matrix. These are native runners
(ubuntu-24.04-arm, macos-14 for both darwin targets) — no QEMU, so
arm64 costs a runner minute, not emulation.
Verified locally on 1.90.0: 8 passed / 0 failed in
vt100_chatwidget_snapshot, 1 passed / 0 failed for the completion test.
hanzoai/dev went public defaulting to someone else's cloud. Four things were
wrong, and all four now have a test that fails if they come back.
DEFAULT PROVIDER AND MODEL. built_in_model_providers() gains `hanzo` -- the
Hanzo Cloud at api.hanzo.ai/v1, Responses wire, bearer from HANZO_USER_KEY --
and it is the default. The default model is zen5-coder. This was not cosmetic:
the old default is not in the gateway catalog, so it 400s against our own
cloud. Measured, not assumed:
POST api.hanzo.ai/v1/responses model=gpt-5-codex -> 400 "model is not
available. Use GET /v1/models to list available models"
POST api.hanzo.ai/v1/responses model=zen5-coder -> 200, clean output
Our own CLI already documented the bug from the other side -- dev.rs says
"Name the model too -- codex's built-in default is not in the gateway catalog
and would 400" and passes `-c model=` on every launch to work around it. It
also asserts that on the native gateway NO model_provider override is needed,
which is only true once `hanzo` is the built-in default. It is now.
zen5-coder over enso because dev is a coding agent and because enso returns
system-prompt text on the Responses wire that dev actually speaks; zen5-coder
returns the answer. Model ids were read from GET /v1/models with a bearer, not
guessed. Other providers stay fully configurable -- this is the default, not
the only choice.
THE LOGIN COMMAND. Messages said `code login` / `codex login`. The real command
is `hanzo auth login` (`hanzo login` is not a command -- it is swallowed as an
AI task). It now lives once, as auth::LOGIN_COMMAND, so no message can drift
into naming a command that does not exist. References to this binary's own
subcommand became `dev login`.
A BINARY NAMED dev. HEAD built `code` and `codex` and nothing named `dev`, so a
release cut today would ship no `dev` -- and `hanzo code` launches a bare `dev`
off PATH, so every new install would break. `dev` is now the canonical bin,
declared first; `code` remains as an alias to the same program, never the
reverse. The CLI identifies as `dev` / "Hanzo Dev", not "OpenAI Codex".
OUR NAMESPACES. The pipeline published to @just-every/* on npm and pushed
formulae to just-every/homebrew-tap. Both of ours already exist and are already
populated at v0.6.91 -- @hanzo/dev plus all five @hanzo/dev-<target> packages,
and hanzoai/homebrew-tap's Formula/hanzo-dev.rb, which installs `dev` and
expects assets named dev-<triple>. Nothing here is squatted; this is our own
distribution, reclaimed. Assets are renamed to match the formula.
Two live supply-chain bugs fell out of that, both worse than a naming problem:
postinstall.js (runs on every npm install) and the tui auto-updater fetched
from a third party's releases -- the updater also told our users to
`npm install -g @just-every/code@latest`. Worse, a shadowed `isWSL` const put
the two fast paths in the temporal dead zone, so their catch blocks swallowed
the error and EVERY install fell through to that download: the five published
platform packages were never used, and the third-party fetch was not an edge
case but the only path that ran. Fixed and exercised in a sandbox across all
three paths. codex-cli/.pack/ -- a committed `npm pack` artifact CI
regenerates, and the reason the bad URL had two homes -- is now untracked.
DURABILITY, because upstream-merge.yml merges openai/codex every 30 minutes.
A one-time edit to a default is a suggestion that survives until the next
merge. Two mechanisms:
- .github/merge-policy.json prefer_ours_globs listed only codex-rs/** while
the workspace that SHIPS is code-rs/**, so it protected nothing that
ships. The identity-bearing code-rs files are now listed.
- code-rs/core/tests/hanzo_identity.rs asserts all four properties -- the
provider, a Zen default, a bin named dev, and no third-party publish
target. Upstream has no such file, so a merge cannot conflict with it or
carry the guard away with the thing it guards. Policy can be edited;
a red build cannot be ignored.
The gate is not decorative: it failed on the un-retargeted pipeline
("release.yml still references `@just-every/`") and went green only when the
pipeline was actually fixed.
Verified: cargo build --bin dev clean; hanzo_identity 4/4; code-core lib
332 passed, 1 failed -- git_info::test_collect_git_info_with_remote, which
fails identically on a clean origin/main checkout here because this machine
has a global [email protected]:.insteadof rewrite. Pre-existing and
environmental, not from this change.
