fix(chv-muse-r12fix-5): UsageLedger.record() 读-改-写原子化(P11)
R12 真机:4 线程 × 10 条记账 0 写错,但 verify_chain 返回
(False, first_bad=11),链 G、链 H 两次复现同一断点;根因是
record() 先 SELECT 链头、再算摘要、再 INSERT 提交,无锁无
事务,两线程读到同一 prev_hash 各写一条,链分叉。修法:
同一实例用 threading.Lock 串行化;SELECT 前 BEGIN IMMEDIATE
持库级写锁(WAL + busy_timeout 下等待而非立即失败),使另一
实例/进程读到的链头必是已提交最新值。record_warning 委托
record(),同款覆盖。新增并发测试:同款 4×10 复测两轮,
verify_chain 全真、40 条一条不丢(旧代码下该测试失败)。
