Clean rename of the 0x9999 settle-only activation gate constant to its accurate name (settle-ONLY since precompile v0.19.1) + a prominent TODO(coordinator) documenting the forward-re-gate constraint for chains WITH 0x9999 matcher history (mainnet). Value unchanged at 1766704800 (Dec-25-2025): a FRESH net genesis'd now (July 2026) is already past this gate, so 0x9999 settle-only is active-from-genesis on it, while the mainnet/testnet/zoo reproduce-tests (gate must sit above their matcher history) stay green. Mainnet forward value is the owner call in the TODO — NOT a source default. Co-authored-by: Hanzo Dev <[email protected]>
