In `@contrib/docker/README.md`:
- Line 9: Update the Nix link in the Docker README so its fragment targets an
existing heading, or remove the link if no appropriate heading exists; preserve
the surrounding explanatory text.
In `@docs/preprocess.py`:
- Around line 339-345: Update _commonmark_list_indent and its list-processing
setup to recognize continuation indentation based on each list marker’s width
plus following spaces, rather than relying on the fixed _LIST_INDENT value.
Preserve CommonMark nesting for single- and multi-digit ordered markers and
variable-width nested markers, and add regression tests covering those cases.

Motivation
The last few pull requests addressed a documentation debt that needed to be filled before this pull request, which itself, is a substrate for work on foreign function interface binds. The challenge with multilingual (or polyglot) codebases is that when combined with linting (both text and semantic analysis), cross-compilation and docs generation, workflows are susceptible to unexpected breakage if not proactively pinned down.
To avoid these issues, alongside documenting the existing development flows for
base-sdkin prior pull requests, the devenv has been declaratively defined as a Nix development shell. This will allow the later FFI-themed pull requests to anchor against a stable cross-compilation capable toolchain with the added benefit of unifying CI and the local environment such that a fix for one case benefits the other.Additional Information
Dependent on sdk%ci: use comment syntax for doc splicing, add
uvlockfile, use for dependency tracking, make CodeQL runner multi-lingual, add symlink linter #33Two shells are available,
#ci(includes Linux cross-compilation support) and#dev(includes macOS and Windows cross compilation support with additional tools for friendlier interactive use), with Docker wrapping the#devshell for consumers who do not wish to setup Nix on their host.The Nix environment is pinned to 26.05 as the current latest, 26.11 drops support for Intel Macs (see NixOS/nixpkgs#535508). Likewise, Apple itself considers the transition finished with macOS 26 with macOS 27 as the last version to support Rosetta (source). This means that support for Intel Macs as a development host is on a best-effort basis and will cease when it's no longer tenable. Support for Intel Macs as a target will follow Dash Core's support policy and will be supported in the immediate future.
CodeQL on ARM64 Linux requires emulation in order to run as native binaries for that platform are still unavailable (see github/codeql#20616), based on newer activity on the issue it appears a native release is the pipeline but for the sake of parity, the emulation path is available to be able to run it at all.
macOS builds will always use the declared Xcode SDK and set the minimum target version as macOS 14 regardless of native or cross-compilation. This is to ensure predictability between builds as the Nix environment has no access to the host's Xcode installation.
To avoid bloating the Nix environment,
rust-toolchain.tomlnow specifiesprofile = "minimal", downstream consumers expectingrust-docswill need to download it manually.Due to a mild divergence in CodeQL lint results between
developand this branch despite running near-identical environments and no changes in Rust code, as a stopgap measure, the specific error has been suppressed to allow CI to pass. This change will be reverted in an upcoming PR.To ensure our Zensical render matches GitHub,
tab_lengthhas been reduced from Python-Markdown's default of 4 to the CommonMark default of 2.The Nix environment doesn't include
rustupas Rust version management is handled by the Nix configuration. As one of the purposes of the environment is to pin the environment,stablebuilds definitionally cannot occur in Nix as stable is a moving target while MSRV and the preferred nightly (defined inrust-toolchain.toml) are fixed targets. Stable builds on GitHub Actions therefore do not use the Nix.How Has This Been Tested?
