Tier: PORT (genuine gap) · single reference file

Add a common-bug-patterns checklist (frequency-ordered: null access, off-by-one, async races, …) run before forming a hypothesis in /cad-debug.

Why: shortcuts the most common bugs before spending a hypothesis cycle or a paid consult.

Cost: one reference file, wired into the debug flow's first step.

Closed 2026-08-08, verified live against cadence-core/references/bug-patterns.md (4,247 B) and cadence-core/workflows/debug.md:69-73. The checklist ships and is wired exactly where this issue asked: step 1 Hypothesize reads it "FIRST, before any candidate is written - it is frequency-ordered, and a pattern whose signature matches the symptom enters the list with its cheapest discriminating check already named."
