MUST switch to sender-scoped replay hashes
Replay detection already uses sender-scoped replay hashes, doesn't it? Afaiu this TIP isn't changing how the replay hash is being calculated.
MUST switch to sender-scoped replay hashes and/or time-wheel cell matches
This feels ambiguous to me, especially the "and/or" part... replay hashes in the time-wheel cells become the only replay detection mechanism, I'm not sure why there's an "or" in here.

Adds TIP-1077 for replacing the expiring nonce ring with a time-wheel replay table sized at 131,072 cells per bucket.
Documents the 256 MiB slot+value footprint, parameter tradeoffs, hardfork migration from the ring layout, and alternatives considered for cleanup and fixed-table designs.
