180-183: Consider documenting the rationale for configuration values.While the frame expiration age calculation is now more adaptive, there's a TODO comment suggesting that these configuration values might need further tweaking. Consider:
- Documenting the rationale for the current multipliers (1x, 2x, 4x).
- Adding comments explaining the relationship between sender and receiver RTO bases.
Would you like me to help document these configuration values or create an issue to track the TODO?

168-174: LGTM! Conditional expiration coefficient aligns with retransmission needs.
The logic correctly reduces the frame expiration age when retransmission is not used, while maintaining a longer expiration time when retransmission is enabled. This change aligns well with the PR objective.
Let's verify that this change doesn't affect any existing tests:
✅ Verification successful
Frame expiration coefficient change is safe to proceed
The verification process shows that:
- The frame expiration change is localized to the Session configuration in
transport/session/src/types.rs - While there are tests in the codebase, none of them explicitly verify frame expiration timing
- The vendor tests that mention "expiration" are unrelated to this session implementation
- The change is a straightforward configuration adjustment that doesn't modify the core session behavior
The modification is safe as it maintains the existing behavior pattern (longer expiration for retransmission, shorter without) while only adjusting the coefficient values.
