Flow Debug

Triggered by: /flow-debug

Find root cause before proposing fixes. No fixes until investigation is complete.

Iron Law

NO FIXES WITHOUT ROOT CAUSE INVESTIGATION FIRST

Phase 1 — Investigate

Read and follow flow-shared/references/session-gate.md (resolve via path resolver in flow/SKILL.md) before updating STATE.

Same-topic failure (matches active plan/spec/patch on this branch) → set phase: debug and investigate. Unrelated topic with active STATE → session gate first; do not overwrite STATE until user confirms.
