唯一目标
以 production-like build 覆盖核心用户流、失败、竞态、Credential 和 false-mode 回归。
固定 E2E matrix
desktop/mobile happy
desktop/mobile amount mismatch
RPC failure
receipt warning
explicit Fixture recovery
double submit / stale response / API timeout
raw drawer keyboard
credential export/verify/tamper
Clear402 false-mode regression
console/network error audit
验收
[ ] 无 flaky retry 隐藏 deterministic failure
[ ] failure trace/screenshot retained
[ ] core scenarios 在 production build smoke
[ ] no uncaught console errors
[ ] network failure UI 与合同一致
[ ] no desktop/mobile horizontal overflow
[ ] semantic assertions，不只 screenshot
[ ] exact count/duration recorded
验证

Codex 指令
扩展跨层 matrix 并运行；不要用 retry 掩盖竞态。发现产品缺陷时保留 trace，
另开一个 root-cause Bug Issue；QA PR 只放 tests/report。
