/**
 * Durable private store for Workflow v3 parameter-distillation proposals.
 *
 * The model-authored suggestion never reaches this module.  `proposal.json`
 * contains only the host-compiled, parsed proposal body.  Immutable proposal
 * material and mutable lifecycle state are deliberately separate so a state
 * transition can never rewrite the object the user reviewed.
 *
 * Lock order is always identity-index -> proposal state.  The durable
 * `replacing` index entry makes supersession recoverable without ever leaving
 * two proposals eligible for approval.
