Scope Mistral's polymorphic reasoning and replay behavior to exact first-party HTTPS routes, preserve stored thinking across real prompt construction, and keep DeepSeek's sanitizer from injecting a second dialect into tool-call history. Align the current model registry, provider-scoped model override, generated facts, docs, and focused route-isolation tests. Split the large stream decoder test module so the source-structure gate remains below budget. Signed-off-by: CodeWhale Bot <bot@codewhale.net>
