Enum DualPpMode 

pub enum DualPpMode {
    Off,
    Forced,
    Auto,
}

MEMRA_DUAL_PP three-state mode for the dual-active PP-2 batched decode path. Default ON (owner flip 2026-08-11) after the box1 PRO-pair re-gate: correctness bit-identity B=1..5, servestress no-thrash, 10-boot soak 929/929 golden matches with 0 slot collisions across 9123 pairs (research/dualpp2-20260811/RESULTS-regate.md), plus the dualpp1 c>=8 interleaved perf floor (+20.753% minimum, research/dualpp1-20260811/RESULTS.md).

The three states carry different failure semantics on purpose:

• Off (MEMRA_DUAL_PP=0): the serial rollback seam. Overlap also follows OFF unless MEMRA_PP_OVERLAP is set explicitly, so one flag restores the exact pre-flip naked path.
• Forced (MEMRA_DUAL_PP=1): the pre-flip explicit request. A placement that cannot run dual (single-slot boundary, host bounce, non-PP-2 fence) REFUSES with the binding quoted reason before any token or cache advance — the gate negative cells pin this.
• Auto (unset): the flipped default. Dual runs where the re-gate validated it (PP-2 fence, double-slot, peer transport, B>=2) and silently degrades to the serial PP-N walker everywhere else — naked PP-3 serving and the MEMRA_PP_HOST_BOUNCE=1 broken-peer escape hatch must keep decoding, not refuse.
