删除： - AUDIT-aria-lsm-v0.7.4.md（50KB） - AUDIT-query-layer-v0.7.4.md（39KB） - AUDIT-storage-engines-v0.7.4.md（39KB） - PLAN-v0.7.5.md（98KB，含附录 G/H/I） 删除前先清除引用面，避免留下断链（共 18 处）： - 源码注释 7 处（change-notifier / kvstore index / column-value / expression / sql-compare / where-matcher / validation）：保留设计意图，引用改为"v0.8.0 审计根因 N" - 测试注释 9 处（opfs.spec / aria-opfs-backend / faulty-backend / storage-harness / v080-b6 / v080-kvstore / v080-query-layer / v080-sql-three-valued / v080-unified-validation / parser）：同上 - CHANGELOG 3 处：改为不依赖已删除文档的自洽表述（B-6 交付物见各条；门禁订正三处 按内容重写），并把变异数量同步为 42 - 校验：三个 md 之间无断链；仓库内已无 PLAN-v0.7.5/AUDIT-* 的任何引用 （git 历史仍可追溯，需要时可 `git show <commit>:PLAN-v0.7.5.md` 找回） 验证：93 套件 / 1985 用例全绿；覆盖率 90.59 / 82.61 / 94.14 / 93.50（阈值 90/82/94/93）； e2e 14/14；lint + 两份 tsc 干净；dist 已重建（注释只影响非压缩产物，min 产物 251,731 B / gzip 63,431 B 不变）。 说明：审查记录的核心内容仍在 CHANGELOG.md（"全量回归审查"与"现场失败修复"两节）， 随 PLAN 一起删除的是附录 G/H/I 的详细表格（门禁逐条验收、交付物清单、未修复项表）。
