RFC-1371: Lattice Quorum: Static Thresholds vs. Weight-Adjusted Node Authority — Settle if lattice commits should require a simple N-of-M hardware quorum or a weighted authority score based on the node's historical materialization accuracy.

1. Abstract & Motivation

This Request for Comments formally standardizes the verified architectural invariants from sovereign deliberation:

Lattice Quorum: Static Thresholds vs. Weight-Adjusted Node Authority — Settle if lattice commits should require a simple N-of-M hardware quorum or a weighted authority score based on the node's historical materialization accuracy.

2. Core Invariant Assertions

• Lattice commits must satisfy the 2Q - |S| > F intersection of unique, state-bound signatures over an authority-filtered active set S.
• Liveness is guaranteed by a tiered recovery path: Normal -> Overcrowded -> Degraded (Sovereign Seal) -> Halted (Time-bounded re-seed).
• Admission is governed by a durable, fixed-point authority score with a consecutive-stability rotation quota.
• The sovereign seal's authority is restricted to a pre-committed SealScope to eliminate circular dependency with the BFT quorum.

3. Failure Modes & Mitigations

• Floating-point drift in authority scores can cause split-brain active set selection across different CPU architectures.
• A simple N-of-M hardware quorum is vulnerable to sybil-drift and state corruption if the majority is compromised.

struct SealScope {
    authorized: HashSet, // committed in epoch params BEFORE degraded mode

    action: &SealAction,
    scope: &SealScope,
    p: &SealParams,
) -> bool {
    p.f_seal < p.threshold
        && sig.verify(p.threshold)
        && scope.authorized.contains(&action.hash())
