Add the missing explicit-path regression so operators keep the current fail-fast contract covered, and record the completed ROADMAP follow-up.
Constraint: scope limited to ROADMAP helper regression coverage plus the DONE roadmap entry; tests/__init__.py is included so the requested python -m unittest tests.test_roadmap_helpers invocation resolves locally instead of an external tests package.
Rejected: changing roadmap-next-id.sh behavior | dogfood showed the script already returns the desired nonzero empty-stdout error.
Confidence: high
Scope-risk: narrow
Directive: Keep stdout reserved for the single next id on successful roadmap-next-id.sh runs.
Tested: python -m unittest tests.test_roadmap_helpers -q; scripts/roadmap-check-ids.sh ROADMAP.md; scripts/roadmap-next-id.sh ROADMAP.md; git diff --check -- ROADMAP.md tests/test_roadmap_helpers.py tests/__init__.py
Constraint: roadmap-next-id.sh must preserve single-id stdout on success while failing closed if duplicate validation cannot run.
Rejected: Relying only on CI/pre-push duplicate checks | the helper is used immediately before appending and must not certify an already-poisoned file.
Confidence: high
Scope-risk: narrow
Directive: Keep roadmap-next-id.sh stdout machine-clean; route validation failures and checker availability errors to stderr, and keep focused helper behavior coverage in the docs/ROADMAP CI path.
Tested: scripts/roadmap-next-id.sh ROADMAP.md printed 725 before appending #725 and 726 after; temp ROADMAP with duplicate 999 exited nonzero and listed duplicate id; scripts/roadmap-check-ids.sh ROADMAP.md; bash -n scripts/roadmap-next-id.sh scripts/roadmap-check-ids.sh; python -m unittest discover -s tests -p test_roadmap_helpers.py; python -m pytest tests/test_roadmap_helpers.py -q; SKIP_CLAW_PRE_PUSH_BUILD=1 bash .github/hooks/pre-push
Not-tested: full cargo workspace build, unchanged docs/script-only path
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
