Detect and recover when a sibling PR's squash-merge silently reverts an upstream PR's content changes because the sibling was based on a pre-upstream main snapshot and its line-level rewrites overlapped the upstream PR's edits. Use when: (1) two PRs are open in parallel against the same file(s) — one refreshing numbers/values, the other rewriting copy/language, (2) the number-refresh PR merges first, the language-rewrite PR merges second, (3) the language-rewrite PR claims…
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
# Stale-Base PR Silently Reverts Upstream Content via Textual Overlap ## Problem You ship PR A: updates 8 specific lines in `templates/foo.html` with new numbers (`50% vs 6%`, `n=117`, etc.). PR A merges cleanly. CI green. In parallel, PR B was opened against `origin/main` BEFORE PR A merged. PR B rewrites copy in the same file for language polish — touching the same 8 lines, but with the OLD numbers (because that's what PR B's base showed). PR B's body claims "all numbers preserved." PR B rebases / `gh pr merge --squash`s after PR A. Git's 3-way merge runs: - **Base** (common ancestor): old text + OLD numbers - **Main side** (post-PR-A): old text + **NEW** numbers ← PR A's contribution - **PR B side**: rewritten text + OLD numbers ← PR B's contribution For lines where PR B's rewrite spans the same text PR A edited, the 3-way merge sees PR B as the "winning" branch-side and takes PR B's version wholesale. **PR A's numbers silently disappear from those lines.** Other files PR A touched but PR B didn't (`app.py`, `intelligence_findings.js`, `library_findings.html`) keep PR A's numbers intact. Result: a **train-serve / display-vs-backend mismatch** that no PR diff, …

How to install
mdr add wan-huiyan/agent-traffic-control/stale-base-pr-silently-reverts-upstream-content@sha256:32aa9825a516e5bfThe line at the top of this page pins the label v1.1.0, 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.
