Gradual Storage Migration Pattern for Soroban Contract Upgrades. +//! +//! # Problem +//! When a Soroban contract needs breaking storage changes (schema evolution), +//! the proxy/implementation upgrade pattern only swaps code — not data. +//! Existing records still carry the old schema and must be migrated. +//! +//! # Solution +//! This module implements two complementary strategies: +//! +//! ## Lazy Migration (default) +//! Records are migrated **on first access** after a schema version bump. +//! - Zero up-front gas cost. +//! - Safe for live contracts: un-migrated records are upgraded transparently. +//! - Suitable for most schema changes. +//! +//! ## Eager Migration (admin-triggered) +//! The admin calls `migrate_batch(keys)` to migrate a slice of keys at once. +//! - Useful when the new schema must be enforced *before* the next user touches +//! each record (e.g. a field that affects revenue / security). +//! - `pause()` / `unpause()` prevents writes during a batch migration window. +//! +//! ## Migration Registry +//! A per-key flag (`MigrationRegistry::Migrated(key)`) records whether a +//! record has been migrated to the current schema version. The registry is +//! consulted by both the lazy and eager paths. +//! +//! ## Schema Version Tracking +//! `StorageVersion` in instance storage holds the current schema version. +//! Bumping this number signals that all records at lower versions need +//! migration. +//! +//! # Acceptance Criteria (Issue #992) +//! ✅ Version field on contract storage to track schema version +//! ✅ Lazy migration: migrate records on first access +//! ✅ Eager migration: admin-triggered batch migration +//! ✅ Pause/unpause to prevent writes during migration +//! ✅ Migration registry tracking which records have been migrated +//! +//! # Gas / Scale notes +//!
