Summary

Canonical NormalizedFinding schema with Severity enum (CRITICAL/HIGH/MEDIUM/LOW/INFO)
Per-project adapters for all 9 analysis tools with severity mapping
CLI pipe interface (stdin JSON → normalized JSON) and adapter registry

Canonical Schema

Field	Type	Description
tool	str	Tool name
category	str	Finding category
severity	Severity	CRITICAL/HIGH/MEDIUM/LOW/INFO
message	str	Human-readable description
file	str?	Source file path
line	int?	Line number
recommendation	str?	Suggested fix
metadata	dict	Tool-specific extras

Severity Mapping Table

Tool	Native Format	Mapping
bus-factor-analyzer	String CRITICAL/HIGH/MEDIUM/LOW	Direct
dep-risk-scanner	String + float 0-10 (computed)	Label-based
doc-drift-detector	error/warning/info	error→HIGH, warning→MEDIUM, info→INFO
knowledge-silo-detector	RiskLevel Enum	Enum value string
perf-regression-spotter	Integer 1-10	8+→CRITICAL, 6+→HIGH, 4+→MEDIUM, 2+→LOW
roadmap-entropy	critical/high/moderate/low	Direct (moderate→MEDIUM)
schema-evolution-advisor	safe/cautious/dangerous	dangerous→CRITICAL, cautious→MEDIUM, safe→LOW
semantic-diff	No severity (categories)	Churn-based heuristic
test-flakiness-analyzer	Float 0-1 (flakiness_rate)	0.5+→CRITICAL, 0.3+→HIGH, 0.15+→MEDIUM

Usage

echo '[{"file": "core.py", "top_author": "alice", "top_author_pct": 85, "num_contributors": 2, "bus_factor": 1, "risk_label": "CRITICAL"}]' | python -m event_taxonomy --tool bus-factor-analyzer

from event_taxonomy.registry import normalize_output
event = normalize_output("bus-factor-analyzer", raw_findings)
print(event.to_json(indent=2))

Test Plan

21 tests passing (schema, adapters, severity mapping)
Integration test with real tool output
