区分时间戳键与索引兜底键。
如果第 0 条 run 缺少 at,而另一条 run 的 at 为 "#0",相同的 (step, need) 会生成相同的 vk。后一条 violation-precedence 因此被忽略。请给两类键使用不同的标记,并增加该组合的回归测试。

一行加固 + 一条用例,方向没问题。一个偏差和一个问题: 你在 #461 的留言写的是「 能不能回到你原本的优先级: 另外小事:留言说用例加在 |
改了什么
src/pipeline.js的suggestRetirements里,前置违规(R1)的去重键在run.at缺失时塌缩成空串,而violationSeen是跨整本账本共享的——于是所有无时间戳的 run,其同(step, need)违规会被并成一条。去重本意是「同一轮里同一条只报一次」,不是「所有轮共享一条」。at存在时走原值,行为逐字节不变。为什么这么修
没用
run.id兜底——run 对象没有id字段:normalizeRun(src/pipeline-runs.js:203)只产出{ at, by, triggeredBy, steps },全仓无run.id引用。位置索引是这里唯一现成的判别项。把「缺失」的判定从
?? ""扩大到含空串——原来是run.at ?? "",run.at === ""时不会走兜底(空串不是 nullish),仍然塌缩。改用已有的isNonEmptyString(src/pipeline.js:240)后,null/undefined/ 空串三种都纳入兜底。at有非空值时完全不变,这是严格更安全的超集。没动
because文案——它仍是run.at ?? "无时间"。后果是两条无at的违规会产出两条文本完全相同的条目(stepId/because/effect都一样)。「产出两条」这个验收满足了,但对人来说两条长得一样不好区分。改文案会动到at存在时之外的输出形状,超出「at 存在时行为不变」的安全区,所以留给你定:如果希望because也带上索引,我补一个跟进 commit。怎么检查的
test/pipeline-r1r2.test.js补两条用例(suggestRetirements的测试在这个文件;不是 #461 评论里提到的pipeline-activities.test.js——那个文件测的是pipeline-activities.js,另一个模块)。Evidence
Before(修复撤回后,
node --test test/pipeline-r1r2.test.js):After(应用修复后,同一条命令):
第二条用例在修复撤回前就是绿的——它锁的是原有去重语义没被修坏,不是为新代码凑的。
全量:
npm test2305 passed / 0 failed;npm run sync+check-sync76 文件平价;git diff --check干净。Merge Danger
Door: two-way。
git revert即可完全回退,无数据迁移、无 schema 变更、无配置键。Blast Radius: 极小——
run.at有非空值时走原值,逐字节不变。唯一的行为变化是
run.at为null/undefined/ 空串时,同(step, need)的跨 run 违规不再被合并。而这个形状在合法账本里不会出现:写入侧normalizeRun(src/pipeline-runs.js:189)与读侧readStoredRun(:262)都强制run.at必填,normalizeAt(:121)对undefined/null/ 空串直接抛错。所以这是防御深度缺口,只在读侧被独立喂入非法形状(或未来写入契约放宽)时触发——与 #461 正文判断一致。消费方是
suggestRetirements的返回数组,形态不变(仍是kind: "violation-precedence"的对象),只是数量可能变多,下游没有按数量做假设。已知边界
at的违规产出后because文本相同(见上)。#${i}是runs数组内的位置,跨调用不稳定——但它只用于单次调用内的键判别,不落库、不对外暴露,所以无需稳定性。Refs #461
