Does Lumen's session driver configuration behave consistently across version upgrades from Lumen 8 to Lumen 10?

Lumen's session driver configuration has exhibited version-dependent behavior since the framework's separation from Laravel's full suite. When migrating session storage from cookie-based defaults to database-backed drivers across Lumen 8, 9, and 10 releases, the underlying driver registration and middleware resolution patterns shift without explicit documentation. This creates uncertainty for projects requiring consistent user session persistence during framework upgrades, particularly when custom bootstrappers or middleware stacks interact with the session layer.

• Which session driver configuration parameters require explicit pinning to preserve behavior across Lumen version boundaries?
• Does the framework's service provider boot order affect database session driver registration in Lumen 10?
• What migration path ensures cookie-based sessions transition transparently to database-backed stores without data loss or middleware conflicts?
