Core Components

fid4.md Consumer app and the most important real-world validation environment.
xflowsdk.md Backend-driven flow engine and the center of most Fidelity behavior analysis.
xflowviewmaker.md Adapter layer historically involved in version bumps, release coupling, and removal evaluation.
ftframeworks.md Consumer-side feature modules that often mediate whether XFlow changes can be validated in Fid4.
cogstore.md Flow-configuration publishing and version-comparison platform used to verify what is live in QA/Production.

Start with xflowsdk.md for backend-driven behavior questions.
Start with fid4.md or ftframeworks.md for consumer validation and release flow questions.
Open xflowviewmaker.md when the question involves version bumps, transitional architecture, or pipeline friction.
Open cogstore.md when the question involves published flow-definition versions, config diffs, or whether a service/config change is live in QA vs Production.
