## What changed - Add `just assemble-codex-package` as the documented entry point for the package builder. - Export `CODEX_REPO_ROOT` from `just` and release CI, and require the package builder to use it for repository-relative inputs. - Resolve the ripgrep and zsh manifests relative to their Python modules.

Codex package builder
This package contains the implementation behind scripts/build_codex_package.py.
The top-level script is the stable executable entry point; these modules keep the
package-building logic split by responsibility.
Run the builder through just:
just assemble-codex-package --help
just assemble-codex-package --variant codex-app-server
just assemble-codex-package --target x86_64-unknown-linux-gnu
The builder creates a canonical Codex package directory:
.
├── codex-package.json
├── bin
│ ├── <entrypoint>[.exe]
│ └── codex-code-mode-host[.exe]
├── codex-resources
│ ├── bwrap # Linux only
│ ├── zsh/bin/zsh # supported Unix targets only
│ ├── codex-command-runner.exe # Windows only
│ └── codex-windows-sandbox-setup.exe # Windows only
└── codex-path
└── rg[.exe]
The package directory is the primary artifact. Archive formats such as
.tar.gz, .tar.zst, and .zip are serializations of that directory.
If --target is omitted, the builder uses the release target for the current
host platform. On Linux, that default is a musl target to match Codex release
artifacts; pass a GNU Linux target explicitly for native glibc local builds. If
--package-dir is omitted, the builder creates a new temporary directory and
prints its path after the package is built.
The --variant flag selects the package entrypoint. Supported variants are
codex and codex-app-server. The --package-version flag sets the version in
codex-package.json; it defaults to [workspace.package].version in
codex-rs/Cargo.toml.
Source-built artifacts
Artifacts built from this repository are built by the package builder in one
grouped cargo build command per package when they are needed and no prebuilt
override was provided:
- all targets: the selected entrypoint, unless
--entrypoint-binis provided - all targets:
codex-code-mode-host, unless--code-mode-host-binis provided - Linux targets:
bwrap, unless--bwrap-binis provided - Windows targets:
codex-command-runnerandcodex-windows-sandbox-setup, unless the corresponding prebuilt helper flags are provided
The default cargo profile is dev-small because local iteration should favor
fast, small builds. Release jobs should pass --cargo-profile release and an
explicit target. Release jobs that already built and signed/notarized the
entrypoint should pass --entrypoint-bin so the package contains that exact
binary instead of rebuilding it.
Release jobs should likewise pass --code-mode-host-bin so the package contains
the signed host executable beside the signed entrypoint.
Release jobs that already built package resource binaries should also pass the
corresponding resource flags: --bwrap-bin for Linux packages, and
--codex-command-runner-bin plus --codex-windows-sandbox-setup-bin for
Windows packages. This keeps package archive creation as a pure staging step
after signing instead of rebuilding resources.
When the builder source-builds an entrypoint for a Darwin or Linux target, it
downloads and verifies the matching Codex-built V8 release pair before invoking
Cargo and sets RUSTY_V8_ARCHIVE plus RUSTY_V8_SRC_BINDING_PATH for that
build. Windows targets keep Cargo's release-build MSVC artifact path. Explicit
overrides remain authoritative when both variables are already set. Set
V8_FROM_SOURCE=1 to leave the build with the v8 crate source-build path.
rg is not built from this repository, so the builder fetches it from the
DotSlash manifest at scripts/codex_package/rg. Downloaded archives are cached
under $TMPDIR/codex-package/<target>-rg and are reused only after the recorded
size and SHA-256 digest have been verified. Pass --rg-bin to use a local
ripgrep executable instead.
The patched zsh fork used by shell_zsh_fork is fetched from the DotSlash
manifest at scripts/codex_package/codex-zsh when the selected target has a
matching prebuilt artifact. Downloaded archives are cached under
$TMPDIR/codex-package/<target>-zsh and installed at
codex-resources/zsh/bin/zsh. Pass --zsh-bin to package a prebuilt, signed
executable, or --zsh-manifest to use a different DotSlash manifest, such as
the manifest published with a standalone zsh artifact release.
