Test Heuristics

Practical test-suite review, design, triage, strategy, and pruning for any testing layer a developer writes, runs, debugs, or maintains. Provenance and grounding sources live in skill.json; this file is runtime routing only.

Core principle

A test exists to catch the bugs that ship in this code class — and to be diagnosable when it fails. A test that passes regardless of bug presence, breaks on legitimate refactor, or fails uninformatively is failing at its job.
