When you run pytest (or any `python -c "import <pkg>"`) from a git WORKTREE but the venv has an editable install (`pip install -e .`) made from the PRIMARY checkout, `import <pkg>` silently resolves to the PRIMARY checkout's source, NOT the worktree code you think you're testing. Use when: (1) you edited code in a worktree, ran the suite, it passed/failed — but you're unsure it exercised the worktree's edits, (2) tests pass on changes that "shouldn't" pass (or fail on changes you reverted)…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Pytest editable-install resolves to primary checkout, not the worktree ## Problem You have one virtualenv with an **editable install** (`pip install -e .`) created from the **primary** repo checkout. You then create a git **worktree** to do isolated feature work, edit code there, and run the test suite from the worktree directory. The suite runs against the **primary checkout's** source, not your worktree edits — silently. Green tests "prove" nothing about your branch; a fix you only made in the worktree looks like it had no effect, or a bug you only reverted in the worktree still appears. ## Context / Trigger Conditions - A `src/`-layout project whose code uses **absolute** imports (`import src.app`, `from mypkg.x import y`) — so the package is resolved via `sys.path`, not via the cwd. - ONE shared venv with `pip install -e .` (or `pip install -e ".[dev]"`) run from the **primary** checkout. The editable install drops a `__editable__.<pkg>.pth` / finder into site-packages that **hardcodes the primary checkout's path**. - You run `pytest` / `python -m pytest` / `python -c "import <pkg>"` from a **git worktree** directory (e.g. `.../.claude/worktrees/feature-x`). …

How to install
mdr add wan-huiyan/agent-traffic-control/verify-pytest-imports-worktree-not-primary-checkout@sha256:648bb4ac30fe5379The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
