Fix `pytest exit 4` ("file or directory not found") when running a test command in a git worktree checked out at an OLD commit. Use when: (1) you're doing historical replay (incident replay, mutation testing, git bisect with tests) and the suite errors out in 1-2 seconds with no test execution, (2) the test command works fine at HEAD but fails at pre-fix SHAs, (3) `pytest scripts/overnight/tests/ <analytics_pkg>/tests/ --tb=no -q` returns…
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
# Worktree historical test replay — missing dirs ## Problem You're replaying historical bugs by checking out each pre-fix SHA in a temp worktree and running the project's canonical test command. At HEAD the command works (e.g. 159 tests collect). At older SHAs you get: ``` ERROR: file or directory not found: scripts/overnight/tests/ no tests ran in 0.01s ``` Exit code 4, duration 1-2 seconds. Pytest aborted before collection because one of the test directories you passed didn't exist yet at that commit. This silently corrupts a historical-replay audit: you can't tell apart "the suite passed and missed the bug" from "the suite never ran." Both look like pytest failures from the outside. ## Context / Trigger Conditions - You're running historical incident replay, mutation testing, git bisect, or any other "check out an old SHA and run the suite" workflow - The project's test layout grew over time (test dirs added, removed, reorganized in subsequent commits) - The test command embeds explicit directory paths: `pytest scripts/overnight/tests/ <analytics_pkg>/tests/ ...` - Pytest exits 4 (`USAGE_ERROR`) in <5 seconds with no test execution …

How to install
mdr add wan-huiyan/agent-traffic-control/worktree-historical-test-replay-missing-dirs@sha256:c29f2034832024b8The 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.
