 ## Claims and evidence
 
 - [ ] Timing wording remains screening-level unless hardware evidence exists
+- [ ] Replay is not described as recreating NIC, switch, or hardware timestamp behavior
 - [ ] Automated deterministic stress is not described as a replacement for live/replay soak validation
+- [ ] Full internal analyzer decomposition is not claimed before it is complete
 - [ ] Screenshots match the released UI
 - [ ] No customer or project-sensitive evidence is included
 - [ ] Known limitations are listed in release notes
