[4444J99]

Fixes the red test jobs on main (bf36cbd5): test (3.11) failed, test (3.12) cancelled by fail-fast.

Defect: root pytest collects the legacy/nexus--babel-alexandria snapshot's tests, but CI only installed the root package (pip install -e .[dev]), which declares no fastapi. Collection died with ModuleNotFoundError: No module named 'fastapi' in legacy/nexus--babel-alexandria/scripts/load_test.py and tests/conftest.py — 142 collected, 2 errors.

Fix (3 files):

• .github/workflows/ci.yml — install the snapshot package with its dev extras (pip install -e legacy/nexus--babel-alexandria[dev]). This brings the snapshot's own declared deps (fastapi, alembic, httpx) and makes nexus_babel importable, which the collected tests need.
• legacy/nexus--babel-alexandria/src/nexus_babel/main.py — the UI test failed on a cwd-relative Jinja2 directory (src/nexus_babel/frontend/templates); the template dir now resolves relative to the package file.
• legacy/nexus--babel-alexandria/Makefile (new) — listed as FILE-006 in the snapshot's MANIFEST but absent from the import; restored with the ten targets the operator runbook documents (db-upgrade, test, lint, openapi-snapshot, certainty, certainty-check, evolution-contract-test, verify, run-api, run-worker), so test_runbook_make_targets_exist passes. Recipes are the runbook's own commands.

Verification (local, exact branch head 6bfa60ec, Python 3.12):

• pytest --cov=. (the CI command): 286 passed, 0 failed (was 142 collected + 2 collection errors before the fix; the 3 tests that then failed locally — alembic missing, template path, Makefile missing — all pass now)
• python -m build: wheel + sdist built
• Isolated scripts/verify_installed_artifact.sh: wheel pass, sdist pass
• make openapi-snapshot: no diff (snapshot current); make -n clean for all ten targets; pytest -k evolution collects 42 tests

Caveats:

• Verified on Python 3.12 locally; this VM has no 3.11 interpreter, so the 3.11 CI leg is unverified locally — but the fix is version-agnostic (dependency install + path resolution + Makefile).
• The verify script hardcodes its workdir under /tmp (512M tmpfs in this VM, too small for the full dep install); ran the identical script with only the workdir relocated to workspace disk.
• Pre-existing, out of scope: ruff check in the snapshot reports 131 errors (root CI lint is continue-on-error); docs/certainty/* artifacts are stale since the chore(legacy): import scrubbed snapshot of nexus--babel-alexandria #42 import (regenerating would stamp a local path and mix ~200 lines of import-scrub reconciliation into this fix, so not included).

Summary by Sourcery

Restore legacy snapshot test and runtime support so CI can execute the full test suite reliably.

Bug Fixes:

• Install the legacy snapshot’s declared dependencies so its tests can be collected and run successfully in CI.
• Resolve frontend templates from the installed package location so UI requests work regardless of the current working directory.

Enhancements:

• Restore the legacy snapshot’s documented Makefile development and operator targets.
• Include frontend HTML templates in built package artifacts.

CI:

• Update CI dependency installation to cover the legacy snapshot exercised by the root test run.

Summary by CodeRabbit

• Bug Fixes
  • Improved app startup so the frontend is located consistently regardless of the directory used to launch the app.
• Chores
  • Added project commands for common development and verification tasks, and included the legacy package’s development tools in CI setup. Installation failures now fail the setup step.

Reviewer's Guide

This PR fixes CI collection failures by installing the legacy nexus snapshot with its dev dependencies, makes UI templates resolve correctly from any working directory, and restores the snapshot Makefile required by runbook tests. Local Python 3.12 verification passes the full pytest, build, artifact, OpenAPI, Make target, and evolution checks; Python 3.11 remains CI-only verification, while existing snapshot lint and stale certainty artifacts are out of scope.

Walkthrough

The PR adds CI installation and Make targets for the legacy Nexus package. It also changes frontend template lookup to use a path relative to main.py.

Changes: Legacy Nexus package

Layer / File(s)	Summary
Development setup and commands .github/workflows/ci.yml, legacy/nexus--babel-alexandria/Makefile	CI installs the legacy package with development dependencies. The Makefile adds targets for upgrades, tests, linting, certainty checks, OpenAPI snapshots, evolution tests, verification, and running the API or worker.
Template path resolution legacy/nexus--babel-alexandria/src/nexus_babel/main.py	The app resolves the frontend templates directory relative to the module file instead of using a working-directory-relative path.

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Bug fix

Merge Risk: Moderate · previous review 6bfa6

The template path change breaks the UI route for any packaged (non-editable) install of the legacy app. Add the template as package data before merging. The certainty artifacts also need regenerating so that make verify can reach its test step.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.

Choose a non-mutating default target.

GNU Make selects db-upgrade when an operator runs bare make. That command runs migrations against the database selected by application settings, even though the operator did not request a migration. Set an explicit, non-mutating default goal so that database upgrades require make db-upgrade. (gnu.org)

Regenerate the certainty artifacts for this change.

Skipping the regen here, deliberately: the committed manifest was already stale before this PR — it was generated 2026-07-06 from the source worktree (176 files, including .github/*, AGENTS.md, CLAUDE.md, GEMINI.md, the two PDFs and the original 61-line Makefile) while the #42 import carries 160 files — so certainty-check already failed before this change, and regenerating now would mix ~200 lines of import-scrub reconciliation plus a sandbox-local root path into a CI fix. It also would not unblock make verify: that bundle runs lint first and the snapshot has 131 pre-existing ruff errors. The manifest regen belongs in a separate cleanup, not this fix.

[coderabbitai]

@4444J99 Understood. The manifest was already stale, and regeneration belongs in a separate cleanup. As you noted, lint also prevents make verify from reaching certainty-check.

Would you like me to open a follow-up issue for the stale artifacts and lint errors?

Include the template in the legacy distribution.

A non-editable legacy install does not include shell.html: the legacy pyproject.toml declares no package data, and the build has no manifest or SCM plugin to include it. The new path therefore makes every /app/{view} request fail, even when started from the snapshot directory. Add the template as package data. (raw.githubusercontent.com)

Review disposition (CI green on 4fe10df: test 3.11 and 3.12, semgrep pass). (1) CodeRabbit 'include template in legacy distribution': already addressed in 4fe10df, [tool.setuptools.package-data] ships frontend/templates/*.html. (2) 'Regenerate certainty artifacts': rejected with rationale in the existing thread (manifest already stale on main; separate cleanup). (3) 'non-mutating default goal' (flagged unverified by CodeRabbit): deferred; the restored Makefile mirrors the runbook target order and nothing invokes bare make. Merging.
