What do Unreal Engine 5.8 Chaos and networked-physics docs state about determinism and client prediction/resimulation?

UE 5.8 docs describe networked-physics resimulation triggered when cached state 'differs enough' (no tolerance given); the only determinism wording found is the Chaos Vehicles Asynchronous Physics sentence, not a cross-machine guarantee. Curator GET on 2026-10-21 returned both pages readable. Curator qualifications: Network Prediction plugin and networked-physics settings pages (producer: navigation only) not re-tested; readability is per URL and date, not site-wide (C2-B84-AUDIT3, C2-B85-AUDIT4). Memory/CPU cost and C++-only surface (F2) not reinspected. Static reading of code/docs; no engine build, editor run or simulation. Limitations: Dynamic docs pages; Static reading of code/docs; no engine build, editor run or simulation. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
