One package manager owns the tree
nodejs/single-package-manager@v1
The project commits at most one lock file, so two package managers do not each believe they own the tree.

Collectors
This guardrail gathers nothing itself. It depends on the collectors below, which the CLI runs once per build before any check, and reads what they found out of GUARDRAIL_FACTS. A collector that collects nothing skips this guardrail rather than failing it.
| Collector | Gathers | Inputs it is given |
|---|---|---|
nodejs | The Node.js project in the project directory: its manifest, the Node version and package manager it asks for, every workspace it declares, the dependencies each manifest names and which of them are pinned, and the lock files committed beside them. | projectDir |
The inputs above are this guardrail's own, passed straight through. Configuring one in buildnote.json changes what is collected, and two guardrails configured the same way share the one collection.

How to fix
Pick the package manager the project actually uses and delete the other lock files. A checkout carrying both package-lock.json and pnpm-lock.yaml installs different versions depending on which command the developer or the CI step reached for, and the one nobody runs drifts silently until the day somebody does.
More in nodejs
nodejs/lockfile-committed. The project commits a lock file, so an install of the same commit resolves the same versions.nodejs/package-manager-pinned. The manifest names the package manager and the exact version Corepack should install.nodejs/version-declared. The project declares the Node.js version it is built and run against, and that version is no older than the configured floor.
