- Mount pprof on an internal 127.0.0.1:6060 engine instead of the public router so heap/goroutine/CPU profiles aren't reachable through the load balancer when PPROF=TRUE.
- Add gqlgen FixedComplexityLimit and a new DepthLimit extension (backend/graph/extension) on /query, /admin, and /public to bound GraphQL DoS surface; thresholds are conservative starting values to be tuned from real-traffic stats.
- Parameterize Filter.DeboostTag in the collection filter SQL builder so CMS-authored tags can't break out of the array literal; existing test updated and a regression test asserts injection payloads land in the args slice, not the SQL string.
