R16.1: Lockfile integrity enforcement

Short answer: CI installs strictly via frozen lockfiles (pnpm –frozen). Without a frozen lockfile CI installs different versions than you tested.

Group: Supply chain. Status: stable. Generated from the rule definitions; do not edit by hand.

What it catches

Lockfile integrity enforcement: CI installs strictly via frozen lockfiles (pnpm –frozen).

Why

Without a frozen lockfile CI installs different versions than you tested.

A bad example

pnpm install

A good example

pnpm install --frozen-lockfile

How it is checked

Nothing yet. No scanner and no slice card checks it: it is a standing rule for authors and reviewers.

How to silence it

A person can silence one finding with brevio-core: ignore R16.1 -- reason on the line or the line above. Without the reason it does not count. An agent cannot silence it: the agent hook and the MCP tools never honour the comment, and a pull request that adds one is reported until a reviewer allows it. Fixing the code is still the better answer.

To change what the rule flags, edit its definition in dev_rules.py or code_rules/__init__.py. That is a code change and is reviewed like one.

R16.2 No wildcard dependency versions
R16.3 Scoped internal packages
