@ -76,8 +76,8 @@ A retry takes a new lookahead sample from current memory.
- Protected BIOS history remains separate and image-derived.
- All data reads within an instruction still use one entry snapshot.
Nominal timing remains based on the current instruction address and existing refill summaries.
Crossing a wait-state window does not yet schedule code cost at the actual lookahead address.
The later [fetch-address timing extension](fetch-address-timing.md) charges non-refill code at the actual lookahead address.
Refill summaries remain destination-based; the instruction-local access kinds and cold-start costs are still nominal.
Per-access device updates, video-bus contention, general DMA handoff, and Game Pak prefetch remain incomplete.
No boundary timing accuracy is claimed.
