cross cutting detection Shipped
What this lens looks for
Find logging calls, error handling patterns, analytics instrumentation, auth checks, caching layers, and retry logic that span multiple groups. Distinguish cross-cutting concerns (should NOT be their own scope group) from shared infrastructure (SHOULD be its own scope group). Test: does removing the concern break dependent groups?
What its verifier checks
Cross-cutting concerns identified and classified; shared infrastructure distinguished from cross-cutting; no cross-cutting concern incorrectly proposed as its own scope group.
