4-phase mandatory investigation protocol before any fix is attempted: Investigate → Pattern Analysis → Hypothesis → Implement. Prevents band-aid fixes by requiring evidence gathering, pattern identification, and a testable hypothesis before touching code. Includes escalation tree, anti-patterns (shotgun debugging, fix-and-pray, symptom fixation), symptom-to-tool mapping, and framework-aware debugging references. If 3+ fixes fail, escalate to architecture review. Use when diagnosing a bug or unexpected behavior, when a quick fix isn't working and the problem keeps returning, when a test is failing and the cause isn't immediately obvious, when a system behaves differently than expected, or when debugging any framework-specific issue (load the relevant tech skill's references/debugging.md for framework detail).

root-cause-debugging
No fix before understanding. Symptoms are not root causes.
4-Phase Protocol
Phase 1: INVESTIGATE — gather all evidence before forming opinions
Phase 2: PATTERN — find what the evidence has in common
Phase 3: HYPOTHESIS — state a specific, testable cause + prediction
Phase 4: IMPLEMENT — fix the root cause, verify with verification-gate
Escalation Rule
If 3 or more fixes fail to resolve the problem: stop. The architecture may be wrong. Surface the pattern to the user before attempting more fixes.
Process
See references/process.md for the full investigation methodology,
root-cause tracing technique, defense-in-depth layers, and
condition-based waiting pattern.
