Five more Plugin implementations release their teardown from a hook the kernel never calls — the #10371 enumeration is short by five

Found while deriving the population for the #10619 teardown-shape gate. Filed rather than fixed — the repairs are the #10371 lane's work, and folding them into the gate's PR would have made it unreviewable against its own card.

The gap

#10371 enumerates six Plugin implementations whose teardown is spelled stop() with no destroy(). Re-derived mechanically over packages/** at main = 78ac958 — every class with an implements Plugin clause, every teardown-shaped method or arrow property it declares — the class is eleven, not six.

The five #10371 does not name split into two shapes, and neither is exotic:

Spelled as an arrow PROPERTY, not a method (a method-only reading of the class misses them):

file	class	alias	what it releases
`packages/metadata/src/plugin.ts`	`MetadataPlugin`	`stop = async (ctx) => …`	closes the artifact watcher, `manager.dispose()`, closes the repository
`packages/runtime/src/app-plugin.ts`	`AppPlugin`	`stop = async (ctx) => …`	emits `app:unregistered` to the control plane
`packages/runtime/src/external-validation-plugin.ts`	`ExternalValidationPlugin`	`stop = (): void => …`	`clearInterval` over every armed drift-check timer

Spelled dispose(), not stop() — the seventh-spelling case #10619 predicts, already present:

file	class	alias	what it releases
`packages/plugins/plugin-email/src/email-plugin.ts`	`EmailServicePlugin`	`async dispose()`	two metadata subscriptions, the live SMTP transport, an engine binding
`packages/plugins/plugin-webhooks/src/webhook-outbox-plugin.ts`	`WebhookOutboxPlugin`	`async dispose()`	stops the auto-enqueuer, unbinds two engine hooks

Why these are the same defect, not near-misses

ObjectKernel.performShutdown() and LiteKernel.destroy() call plugin.destroy() and nothing else. Verified on the same revision: nothing in the tree calls stop(), dispose(), close() or shutdown() on a plugin. EmailServicePlugin.dispose() has exactly one caller in the whole repo — a test (email-plugin.template-runtime-write.test.ts); WebhookOutboxPlugin.dispose() has none at all.

ExternalValidationPlugin is the one that raises the stakes above "listed for whoever sweeps": it is the only instance besides plugin-reports that owns setInterval timers, and its stop() is reached only from scheduleDriftChecks() re-arming itself. On kernel shutdown those intervals are never cleared — the #9371 mechanism verbatim.

Shape of the repair

The same one PR #10375 applied: move the body into destroy() and keep the old name as a delegating alias, because it is public API of an exported class.

Status in tooling

All eleven are baselined in the #10619 gate's KNOWN_TEARDOWN_UNREACHED list, which is shrink-only and closed to new members. Deleting an entry as each plugin is repaired is the intended burn-down; a stale entry fails the gate, so the ledger cannot drift out of step with the repairs.

Triage: pm:queue confirmed (domain:services kept, type Bug). This is a five-member family repair with an established remedy (the PR-10375 shape: move the body into destroy(), keep the old spelling as a delegating alias on the exported public API). The file surface spans three lanes' packages — packages/metadata (engine), packages/runtime x2 (cli), packages/plugins/plugin-email + plugin-webhooks (services) — but the change is one mechanical shape with per-file proofs, so splitting it three ways buys nothing: cross-domain single-dispatch exception applies, designated lane = domain:services (the parent 10371 lane, which owns the defect class). Claim must declare the full five-file surface; family-dispatch five-gate check applies (all members already ruled by the parent's precedent; per-member commit + per-member assertion; exclusion list = the six members 10371 already names, which stay with 10371's own dispatch). Serial constraint: coordinate with the 10371/10619 lane — the KNOWN_TEARDOWN_UNREACHED baseline in the 10619 gate must shrink in the same PR as each repair. Size/model suggestion: M, opus.

✅ 串行栅栏已解除，且基线状态我已核对

PR #10766 已于 2026-08-21T13:32Z 合并，scripts/check-plugin-teardown-shape.mjs 现在无人持有。我在 main @ 507f174ec 上量过基线：

真实条目（packages/ 前缀）：5 —— 正是你的五个
  metadata/src/plugin.ts · plugin-email/email-plugin.ts · plugin-webhooks/webhook-outbox-plugin.ts
  runtime/app-plugin.ts · runtime/external-validation-plugin.ts

⚠️ 计数注记，替你省一个坑：直接 grep -c "repair: '#10371'" 会返回 6 —— 多的那个是门禁自测 fixture 里的 a/src/p.ts。范围限定到 packages/ 前缀才是真实条目数。

⭐ 删基线条目的方法是被规定的，不要按行号

先跑一遍门禁，让它自己报出「哪些条目 no longer unreached」，用那份失败清单作为删除依据，再逐一确认每个都真有 destroy()。这是 #10766 用过的方法，比按行号删强得多：行号会漂移，而删错一条 = 假声明某个插件已修。

⛔ 一件 #10371 交接给你的事

那五条都带 repair: '#10371'，而门禁判词行打印 repair tracked on #10371 —— 那张卡现在已经关了。任何从门禁输出跟着这个号码过去的人会落到一张关闭的卡上。

⇒ 修每个成员时把它那条的 repair 字段改成 #10772（若该条随修复被删除，就不存在这个问题；若你分批保留任何一条，它必须指向本卡）。

实现要求

前提先自己复现，不要采信卡面。卡面在 main = 78ac958552 上机械重推得到 11 个（不是 plugin-reports: the timers started by ReportsPlugin are released from stop(), which the kernel never calls #10371 的 6 个），而 main 已经动了很远。在你的树上重新推导，报出你测到的总数与五个成员的当前形态。
⚠️ 卡面自述这五个分两种拼法，而**「只按方法读」会整个漏掉前三个箭头属性** —— 这正是 plugin-reports: the timers started by ReportsPlugin are released from stop(), which the kernel never calls #10371 的普查短了五个的原因。你的复现必须能同时看见两种拼法。
ExternalValidationPlugin 是承重成员：卡面称它是除 plugin-reports 之外唯一拥有 setInterval 的实例，其 stop 里是 clearInterval 扫掉每一个已武装的漂移检查定时器，而该 stop 只被 scheduleDriftChecks() 自我重新武装时触达 ⇒ kernel 关机时那些 interval 从不被清除，flaky: a vitest worker teardown race (EnvironmentTeardownError: Closing rpc while onUserConsoleLog was pending) fails app-showcase with 334/334 tests passing #9371 机制原样重现。
⚠️ 自己量它，不要从卡面转抄。plugin-reports: the timers started by ReportsPlugin are released from stop(), which the kernel never calls #10371 上「5 个定时器点」实为 1 个（另外四个是注释/类型标注/日志字符串）—— grep 命中数不是事实数，这个坑本车道今天已经踩了三次。
dispose() 那两个的调用方普查：卡面称 EmailServicePlugin.dispose() 全仓只有一个调用方（一个测试），WebhookOutboxPlugin.dispose() 一个都没有。零命中判断必须带阳性对照：用邻近的已知存在项（例如 plugin.destroy() 的调用点数）证明搜索有效，再宣布那个零。
每个成员一次提交 + 每个成员一条独立断言（分诊的 family-dispatch 要求：per-member commit、per-member assertion）。
双向 pin：① kernel.shutdown() 之后资源确实被释放（ExternalValidationPlugin 的 interval 必须有它自己的那条）；② 直接调旧名（stop / dispose）的既有嵌入方行为不变 —— 这是保留别名的全部理由，只钉①会让一个「把旧名删掉」的实现全绿；③ 每个成员各有一条「destroy() 被 kernel 触达」的独立断言。
消融：预测签名先写后跑，双向；git hash-object 证明恢复逐字节一致；用阳性对照证明（非断言）测试解析的是 src/ 还是 dist/。
Changeset 必须有。我的首判是不破坏（只增 destroy()、保留旧名），所以 patch 应正确 —— 但以你的测量为准；若判定破坏性，仓库约定走 minor 并需 ADR-0087 标记。
⭐ 仪器事实：check-adr-0087-registration 从 git 读 changeset，不读工作树 —— 未提交就跑它会得到不携带信息的绿。
门禁并集：node scripts/pm/dispatch-gates.mjs 不带路径参数推导，最终提交之后、干净工作树上跑；退出码在任何管道之前捕获；引用每道门禁自己那行判词。
⚠️ class [finding] Every PM dispatch list is short by the same ~5 changeset-triggered gate families — they are path-derivable, but the changeset does not exist yet when the list is derived #10309：额外显式跑 pnpm check:route-envelope 与 pnpm check:dispatcher-error-vocabulary（各带 --self-test），并报告推导是否点名了它们。
⚠️ 必跑：node scripts/check-plugin-teardown-shape.mjs（真跑 + --self-test），并报出你观察到的 held 数。⛔ 注意：pnpm check:plugin-teardown-shape 这个脚本名不存在，会退出 254 Command not found，而接进管道会读成绿 —— 直接调 node scripts/…mjs。
⛔ @objectstack/plugin-auth TEST_DEBT 记 109（[finding] @objectstack/plugin-auth's TEST_DEBT records 109 where tsc now reports 98 — an 11-error surplus opened by PR #10614 #10615）：不要动、不要跑 --lower。
开 draft PR（Fixes #10772）。⛔ 不翻 ready、⛔ 不武装 auto-merge、⛔ 不合并。

不是你的

#10619 的守卫判据属 devx 车道。⛔ 不要在本 PR 里造它。但你的工作会给它证据：#10371 的 dev 指出「声明了 stop() 且没有 destroy()」这个判据在修完之后会永久变绿，而你手上这两个 dispose() 成员正是他预言的「第七种拼法」的活体。测到什么就写进报告，我转给那张卡。

常备仪器陷阱（今天全部实测）

⛔ 不要跑 scripts/check-single-claim-paths.mjs（无 PR_NUMBER → NOT WIRED；有 PR_NUMBER 无 token → GitHub API 401；两种都是接线故障不是判词，接进管道会把 401 回溯读成绿）。
⭐ 改 node_modules/ 下文件前先查硬链接数（实测有 vendor 文件带 6 个硬链接指向共享 pnpm store）。
⭐ 绝不 git reset --soft origin/main —— 那个 ref 跨 worktree 共享、会在你脚下前进，reset 会把别人已合并的文件 staged 成你的（[finding] refs/remotes/origin/main is shared across worktrees too — another agent's fetch advances it under you, and git reset --soft origin/main then stages their merged files as yours #10743）。reset 到开工时记下的 base sha。

Claim: re-dispatch — the previous seat's work survives, this is verification and push, not a redo.

session: user-29 [974948]
branch: claude/issue-10772-teardown-five-more (exists; remote at 37ba31a4b)
worktree: /home/user/objectstack-10772, HEAD 66d2bfe96, working tree clean
Clause-②: no — this restores teardown to the hook the kernel actually calls; it adds no public surface and changes no contract accept/reject set.
serial constraint: holds scripts/check-plugin-teardown-shape.mjs and the five plugin sources. No other services-lane card may take that baseline until this lands.

Why re-dispatched

The previous agent is gone. Checking the remote alone would have read as "no work done" — the remote branch is 7 commits behind the local worktree. Checking the worktree instead (the lesson recorded on #10424) found the work complete and committed:

66d2bfe96 test(webhooks,email): satisfy check:engine-double-contract for the two new fakes
f28766002 chore(changeset): patch for the five #10772 teardown repairs

a667377ec fix(metadata): MetadataPlugin releases its repository from destroy(), not stop()

14 files, +1206/-31, one changeset, all five plugins, plus the baseline edit and an engine-double-contract.pinned.json update.

⛔ Nothing above is accepted as done. Commits are a claim, not a measurement — none of these gates were re-run by me, and the previous seat filed no report. The incoming seat verifies from zero.

Known traps on this specific card

scripts/check-plugin-teardown-shape.mjs is shrink-only by its own words (:225 ⛔ SHRINK-ONLY., :136 "a stale entry is itself a failure"). All five entries are still repair: '#10371' on origin/main at 81845c65a (:236-:240). Repairing a plugin means deleting its entry, not retagging it — and a stale entry left behind is itself a failure.
⚠️ A bare grep -c "repair: '#10371'" returns 6, not 5. The sixth is the self-test fixture at :667 ({ file: 'a/src/p.ts', … }) and must not be touched. Count with the packages/ prefix.
plugin-reports: the timers started by ReportsPlugin are released from stop(), which the kernel never calls #10371 is closed. Do not cite it as the live repair owner.
The base may be behind origin/main (now 81845c65a); fix(plugins,connectors,services): release plugin resources from destroy(), the hook the kernel actually calls #10766 nearly turned main red on exactly this file because its base predated the gate. Rebase or merge before measuring, and measure after.

VERIFIED (not changed): all five plugins tear down from destroy() with the old spelling retained as a delegating alias; the five KNOWN_TEARDOWN_UNREACHED entries are DELETED, not retagged, and the gate's verdict line no longer cites the closed #10371 as live repair owner; the self-test fixture at :675 is untouched; the changeset is patch across the four packages and is committed; the engine-double work removed two unserved verbs from the webhooks double instead of pinning them, and pinned only the one email double that routes through assertEngineUpdateDispatch, leaving engine-double-contract.baseline.json alone. CHANGED BY ME: base was 67 commits behind origin/main (branch base 37ba31a4b vs origin/main 81845c65a) — merged origin/main into the branch as 019b06738 BEFORE any measurement, since a baseline measured on a stale base is exactly what nearly turned main red on this file once before; every number in this report is from that commit on a clean tree. Also reset a file MODE flip (packages/create-objectstack/bin/create-objectstack.js 100644->100755) that pnpm install introduced, so it is not in the PR. Remote was 7 commits behind local at start; both the backlog and the merge are now pushed. Premise re-derived independently on origin/main @ 81845c65a: each of the five files' only teardown-shaped member there is the alias, no destroy() anywhere (plugin.ts:549, app-plugin.ts:1422, external-validation-plugin.ts:182, email-plugin.ts:1255, webhook-outbox-plugin.ts:172).",

ABLATIONS — prediction written down BEFORE each mutation (file kept at scratchpad/issue-10772/ablation-predictions.txt), every restore proved byte-identical with git hash-object. A1 stale-baseline control: PREDICTED exit 1 naming all five packages/ entries stale, proving repair = DELETE not retag. OBSERVED exit 1, '5 stale KNOWN_TEARDOWN_UNREACHED entry/entries' listing all five with '-- no longer unreached' and 'delete each line above'. Restore 5e93066ba709b5479abdc409c7f3582c70406769 -> 5e93066ba709b5479abdc409c7f3582c70406769. A2 revert the load-bearing member (external-validation-plugin.ts back to its origin/main bytes): PREDICTED (a) gate exit 1 naming the class with 'no destroy()' plus the do-not-widen refusal, (b) the pin test red on getTimerCount and on a climbing validateAllCalls and on plugin.destroy being undefined, (c) dist bytes unchanged. OBSERVED (a) exit 1 'packages/runtime/src/external-validation-plugin.ts:159 ExternalValidationPlugin.stop() -- no destroy()' + the refusal text; (b) 'Tests 4 failed | 2 passed (6)' with 'expected 1 to be +0', 'expected 7 to be 2', 'TypeError: plugin.destroy is not a function'; (c) confirmed. Restore 9c370df26dd428018fe02d046f2511e275b5eff1 -> 9c370df26dd428018fe02d046f2511e275b5eff1. REBUILD QUESTION, ARGUED FROM THE FILES: no rebuild sits between edit and run, and that is the proof. The pin test imports './external-validation-plugin.js' — a RELATIVE specifier vitest resolves into packages/runtime/src/ — so a src-only edit is sufficient. NO build command was run between the mutation and the observation, and `git hash-object packages/runtime/dist/index.js` read 6c9145953c9ff3681352bc9a706e6d54948402da both BEFORE and AFTER while the verdict flipped green -> 4 failures. packages/runtime/dist DOES exist and DOES carry the repair (built 2026-08-21 14:44 by the previous seat), so its staleness is not the discriminator — the identical-bytes-across-a-flipped-verdict is. A dist-resolving suite could not have moved. A3 the OTHER direction (delete the retained stop alias, keep destroy): PREDICTED gate stays GREEN and only the alias legs go red, proving the gate alone cannot see an alias deletion. OBSERVED gate exit 0 '0 known-unreached'; test 'Tests 3 failed | 3 passed (6)' with 'TypeError: plugin.stop is not a function' on both alias legs. Restore 9c370df26… -> 9c370df26… A4 is the new vitest.config load-bearing: PREDICTED removing packages/plugins/plugin-webhooks/vitest.config.ts reds check-test-source-alias naming @objectstack/core. OBSERVED exit 1 'NEW unaliased artifact import(s) since this entry was measured: @objectstack/core … Alias them in the package's vitest.config.* — widening the registry entry is not the fix.' Restore 1851931a9fc48aaa927e8c194d36371d65a29980 -> 1851931a9fc48aaa927e8c194d36371d65a29980. No registry entry was widened. ZERO-HIT COUNTER-CHECKS, each with a positive control on the same corpus: (1) dispose() callers — positive control 58 `.destroy()` sites under packages/ non-test sources (non-zero, so the expression finds what exists); against that EmailServicePlugin.dispose() had exactly ONE pre-existing caller repo-wide (email-plugin.template-runtime-write.test.ts:375) and WebhookOutboxPlugin.dispose() had ZERO. Card confirmed. (2) setInterval census — enumerated every non-test `implements Plugin` source under packages/ and tested each for setInterval(: exactly TWO hit (plugin-reports/src/reports-plugin.ts and external-validation-plugin.ts), a non-zero result from an enumerator that named its hits. Within external-validation-plugin.ts the real armed-timer site is ONE (line 294); the other 'setInterval' occurrences are a type annotation (165) and two prose mentions (191, 194) — a grep hit count of 3 would have been a false fact count.",
