Add a lightweight regression for the documented local pre-push build gate so the skip hatch and lockfile-grade cargo build command stay aligned with operator docs.
Constraint: Issue #696 scope is limited to pre-push hook contract drift after ROADMAP #694.\nRejected: Reworking the hook harness or roadmap board | unnecessary for the focused drift guard.\nConfidence: high\nScope-risk: narrow\nDirective: Keep the hook docs, skip hatch, and cargo --locked command in sync when changing local push gates.\nTested: bash -n .github/hooks/pre-push; python3 tests/test_pre_push_hook_contract.py -v; git diff --check\nNot-tested: Full cargo workspace build; Rust code was not touched.
The old tracked TypeScript snapshot has been removed from the repository history and the root directory is now a Python porting workspace. README and tests now describe and verify the Python-first layout instead of treating the exposed snapshot as the active source tree.
A local archive can still exist outside Git, but the tracked repository now presents only the Python porting surface, related essay context, and OmX workflow artifacts.
Constraint: Tracked history should collapse to a single commit while excluding the archived snapshot from Git
Rejected: Keep the exposed TypeScript tree in tracked history under an archive path | user explicitly wanted only the Python porting repo state in Git
Confidence: medium
Scope-risk: broad
Reversibility: messy
Directive: Keep future tracked additions focused on the Python port itself; do not reintroduce the exposed snapshot into Git history
Tested: python3 -m unittest discover -s tests -v; python3 -m src.main summary; git diff --check
Not-tested: Behavioral parity with the original TypeScript system beyond the current Python workspace surface
