[Great catch — this is exactly the right distinction. The default Action / MockLLM path is fixture-bound: a green gate proves the bundled corpus + reference chunker still pass policy, not that your app chunk-size change would fail Retrieve. I shipped that clarification in SentinelRAG 0.2.2: Docs/Action now state fixture vs app binding explicitly evidence.json stamps app\_revision + chunker\_config sentinelrag-gate app-bound-check runs the unmodified chunker, then a known harmful chunk-size change, remaps relevance by gold text so cases stay the same, and requires Retrieve to regress pip install -U sentinelrag uv run sentinelrag-gate app-bound-check That establishes what the green MockLLM path actually protects before extending claims to prompt/model changes. Thanks for pushing on the real failure mode.](https://hashnode.com/posts/the-rag-change-that-looked-fine-until-production-users-caught-it/6af08cfc5ee6983369f4e449/comment/6af155493097fe7d1baf936f#reply-6af165f168fd16fccf9c0452)
