…metadata
FlextLazy.install wires __getattr__/__dir__/__all__ but never published
the normalized map. Runtime metadata readers — _child_map (parent merge)
and the beartype helpers lazy_alias_suffixes/runtime_alias_names — read
vars(module)['_LAZY_IMPORTS']. Roots generated with the inline-install
shape (no module-level literal) therefore exposed NO metadata:
runtime_alias_names('flext_infra') returned empty, alias shadow/block
detection in the flext-infra import modernizer collapsed, and two of its
unit tests failed on 0.12.0-dev.
install() now publishes the normalized map into module globals, making
the metadata contract hold from the single owner for both install
shapes (module-level literal and inline call).
Evidence: flext-infra tests/unit/refactor/test_infra_refactor_import_modernizer.py
2 failed -> 12 passed; flext-core tests/unit/test_lazy_exports.py 23 passed.
📝 WalkthroughWalkthroughThe PR scopes GitHub Actions permissions, updates Markdownlint and development tooling, and replaces empty package exports with generated lazy-import configurations across Flext Core packages. ChangesWorkflow and development tooling
Generated lazy package exports
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟠 High · up to The package initialization changes currently prevent twelve affected modules from importing, which can make downstream applications fail at startup; the dependency lock is also inconsistent with the declared tooling requirement. These merge-blocking correctness and reproducibility issues should be fixed before merging, with the workflow permission and public-export concerns handled as follow-up.

… install 'make gen WHAT=apply APPLY=Y' with current flext-infra@0.12.0-dev regenerates every package initializer to the inline-install shape plus the current Makefile/pyproject/docs.yml projections (CI 'gen (blocking)' compares against exactly this fixed point). The lazy metadata contract these initializers relied on is now guaranteed by FlextLazy.install publishing _LAZY_IMPORTS, so no module-level literal is needed. Evidence: gen apply reached fixed point (changed=3 then clean); tests/unit/test_lazy_exports.py 23 passed post-regeneration.
CI 'check (blocking)' runs the markdown gate under CI=Y; without the generated .markdownlint.json/.markdownlintignore the gate ran rumdl on defaults over the whole tree (437 MD013/MD046/MD051 findings from docs and .serena memories). The projections render tooling.yaml markdown rules/excludes — the same SSOT every FLEXT repo consumes. Evidence: CI=Y make check → markdown 0 errors, smells 0, security 0, pyright 0, mypy 0 (Total: 1 Success: 1 Failed: 0).

__all__tuples publish private submodule names. The generator adds underscore-prefixed submodule names topublic_exports, soimport *binds internal modules as public API. Keep the names in the lazy map for attribute access, and exclude them frompublic_exports.

CodeRabbit: uv.lock still recorded mypy 2.3.0 with a >=1.20.2 spec while pyproject.toml requires >=2.3.1 under the exclude-newer-package cutoff. 'make deps WHAT=lock APPLY=Y' on a standalone clone regenerates the lock: mypy 2.3.1, specifier >=2.3.1.
