cad-debug

Debug a symptom by the scientific method - form hypotheses, run the cheapest discriminating test for each, confirm a root cause, fix it, verify the symptom is gone. The investigation is persisted to `.planning/debug/.md` after every step, so a `/clear` or a new session resumes it losslessly. At a genuine dead-end (repeated failed fixes, exhausted hypotheses), OFFER a second-model consult (references/consult.md) - user-gated, decision-support only.

Routing: parse $ARGUMENTS per the workflow's Route table (debug.md) - list, status <slug>, continue <slug>, --diagnose, else a new symptom. The table lives in the workflow, once.

<execution_context> @${CLAUDE_PLUGIN_ROOT}/cadence-core/workflows/debug.md </execution_context>

Route on `$ARGUMENTS`, then run the debug workflow single-pass end-to-end. Persist the state file after every hypothesis test and fix attempt. Never auto-loop fixes and never auto-consult - both are deliberate, and the consult is always user-gated.
