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

# AGENTS.md — the fence

This repository vendors other authors' writing **byte-for-byte** and proves it with
hashes. Most files here are not editable, even to fix a typo. Before touching ANY
file, look it up in `foundry/MANIFEST.json`.

## The five rules

1. **Never retype vendored content.** Bytes enter this repo only through
   `foundry/scripts/lift.sh`. If you find yourself reproducing text from an upstream
   repo in your own output, stop — run the script instead.
2. **Locked files are never edited.** Classes `verbatim`, `verbatim-minus`, and
   `distilled` are hash-locked; CI fails on one changed character. If a change seems
   needed, propose it: a re-lift (upstream changed), a ledger ruling (we disagree with
   the content), or an upstream PR (the content has a bug). Never edit in place.
3. **Every change is a logged event.** Append one line to `foundry/LOG.md` for any
   provenance-changing action. Scripts log their own actions. Never edit existing lines.
4. **Upstream drift is classified, never auto-merged.** You may draft re-lift PRs and
   drift issues; only a human merges. See the runbooks.

How to install

The exact contents, by fingerprint
mdr add backnotprop/product-engineering/AGENTS.md@sha256:f63f631ce444adbc

The line at the top of this page pins the label git:20260826.1ad8694, 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.
