Source Freshness Rules

Category	Max Age	Rationale
Security vulnerabilities	6 months	Rapid threat evolution
Framework versions	1 year	API/practice changes
Cloud service docs	1 year	Frequent deprecation/launch
API references	1 year	Breaking changes common
Architecture patterns	Evergreen	Core patterns stable
Methodology references	Evergreen	Foundational works stable
Language specs	Evergreen per version	Per-version permanent
Research papers	3 years	Check for follow-up work
Industry trend reports	1 year	Cite current edition only

Handling Outdated Sources

1. Check if newer version exists
2. Stable concept: cite with "[Published {year}; concept remains current]"
3. Time-sensitive: find current source or document age limitation in Knowledge Gaps
4. Never cite outdated security advisories as current threat intelligence
