Maintenance & freshness
AI architecture content decays quickly. Each chapter carries a Last reviewed date and separates durable principles from time-sensitive product mappings.
Review cadence
| Content type | Review target |
|---|---|
| Architecture principles and SA methods | Annually |
| Security patterns and threat taxonomies | Every 6 months |
| Regulation and governance | Every 3–6 months and on major changes |
| Model, platform, price, and product comparisons | Quarterly |
| External links and lab dependencies | Monthly automated check |
Material claims about vendor capabilities, prices, model context limits, benchmark results, or regulation must include an as-of date and a primary source. When facts change, preserve the architecture lesson and update the mapping.
