Use when reviewing code, a diff, a module, an architecture, or a design/spec document against house standards - including multi-expert panel reviews ("review with a DDD expert and an asset-finance expert"). Also when running a removal-first simplification sweep: "what can we remove", "product simplification review".
Use when executing an implementation plan or building a scoped feature or fix - after scope is clear, before code gets written. Triggers on "implement the plan at PATH", "start slice SP-2b".
Use when investigating any bug, error, crash, stack trace, failing or flaky test, incident, regression, unexpected behavior, or "why is this happening" question - before proposing or applying a fix.
Use when an implementation needs proof against the live running stack: after build completes, before ship, or when asked to verify, e2e-test, smoke-test, or demo that an API, UI, or DB change actually works.
Use when building or styling sportsbook, betting, or casino (iGaming) interfaces: odds displays, betslips, live-event states, suspended markets, casino game grids, or wallet and money surfaces.
Use when writing or reviewing code that posts, holds, voids, reverses, or reconciles money movements - double-entry postings, wallet balances, idempotency keys, FX conversion, or Blnk / pgledger integration.

Use @WebMvcTest when controller contract behavior changed and Testcontainers when persistence behavior changed. Add only the layers needed to prove the change.
