Pin ruamel.yaml before the release that requires ruamel.yaml.clib on
Python 3.14. Windows ARM64 has no clib wheel, and source builds fail in
CI's long temporary paths. Refresh both application and PM locks and
keep wheelhouse tests aligned with the locked pure-Python runtime.
Standalone Python cannot locate the system CA bundle on this NixOS host.
Use the shell-staged uv to prepare the independent PM runtime before PM
fetches managed Python. Declare and lock truststore in that runtime, then
activate it before CLI and worker imports construct HTTPS clients.
Make setup's awk pin reader follow object nesting rather than indentation.
Use the same reader for tool versions and artifact fields.
Verified cold activation with CA overrides removed, pinned Python and uv
downloads, pm doctor, and a public worker HTTPS install. The targeted suite
passed 56 tests with one Windows-only skip. The TLS regression fails when
truststore is installed but entrypoint activation is removed. Bash syntax
and Ruff checks passed. The full suite was not run.
Two additional setup-toolchain tests fail on unchanged HEAD because their
fixtures reach the real home before home isolation. CI bootstrap unification
is not part of this change.
Activation reaches plugin discovery before the application dependencies
exist. Give PM its own locked Python project and runtime so it can install
or repair the application without importing that dependency tree.
Keep PM outside the application workspace. A shared uv workspace resolves
the application graph and cannot provide this isolation. Route mutations
through an isolated worker and preserve transaction callbacks, cancellation,
custom package registrations, and correlated receipts.
Use the same runtime builder for source installs and packaged payloads.
Keep offline wheelhouse support in that builder. Nix builds the independent
PM lock as a separate derivation. Refuse lazy-disabled bootstrap before
installing tools or dependencies.
Move first-party YAML readers and writers to ruamel. Keep the application
lock's transitive PyYAML requirements for third-party packages.
Verification:
- Focused canonical Python suite: 177 passed, 1 host-gated skip.
- Electron backend probes: 12 passed. Electron typecheck passed.
- Both uv locks, scoped lint, Bash syntax, and whitespace checks passed.
- Cold activation, corrupt-app repair, offline staging, and relocation ran.
- Built and exercised the Nix PM runtime and standalone YAML merge script.
Six broader caller test files retain the same 24 failing test IDs as an
archive of HEAD. The existing real-home guard blocks those tests before
they can exercise the affected paths. No full-suite pass is claimed.
Native Windows signing and full Bionic package execution remain unverified.
