Unit Testing for the PlugJS Build System ========================================
Guardis is a modular library of type guards, built to be easy to use and extend.
Zero-dependency invariant checks that materialize into real tape-six assertions under test, and stay inert (or configurable) in production.
Asserter agent and assert command (static pre-testing quality gate) plus audit scan — detects N×M concern accumulation across sibling directories.
Assertion toolkit for Puppeteer.
TypeScript-first test assertion functions with precise type narrowing
Tiny, type-safe assertions — invariant/assert with TypeScript narrowing, assertDefined, assertNever exhaustiveness, ensure, and lazy messages. Zero dependencies.
