Apply after an audit, scoring review, or a request for a "real classifier" / "less arbitrary weights" when existing scorers, rankers, or weight formulas were already named. Pick among those named gaps before proposing a new model or library.
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
# Bind to Named Inventory
After an audit (or any pass that names N existing scorers/rankers/formulas
and their failures), the next plan must pick among **those named gaps**.
Do not add a new model, library, or parallel scorer until each named system
is mapped: what it scores, whether its weights are literal or labeled, and
which failure the user is pointing at.
**Must always:**
- Bind phrases like "real classifier" or "these weights are arbitrary" onto
a named scorer from the inventory ("the `.5/.3/.2` mix is finding-priority
ranking; flag `a` appearing in two frauds is `fraud_learning` case
frequency") before proposing sklearn, logistic regression, or a new file.
- Prefer replace-or-feed an existing scorer over adding a fourth.
- If the user is not comfortable with ML, teach the existing named scorers
first. Offer a no-library path before a new dependency.
**Must never:**
- Box the user into a new prediction target that was not in the audit.
- Treat "I need a real classifier" as license to invent a model while an
exact-string transfer gap already named in the same session sits unused.
**Battle-tested:** A scoring audit named three heuristics and that held-out

How to install
mdr add edbertchan/catstack/principle-bind-to-named-inventory@sha256:17915fb67b55f240The line at the top of this page pins the label git:20260910.26ee82b, 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.
