 ## Notes
 
 - Current versions intentionally favored iterative validation over final architecture purity.
-- The current listener runtime is considered a stepping stone, not the final source-runtime model.
+- The autonomous WS source refactor is now started and validated enough to continue as the main direction for `0.6.x`.
+- The Tauri migration is intentionally separated into `0.7.x` so transport/runtime stabilization can happen first.
 - Candidate/correlation layers may continue to evolve before stabilizing.
 - Future versions may be renumbered, merged, split, or reprioritized depending on what real Solana traffic reveals.
