[finding] hook.retryPolicy.maxRetries has two answers: schema .default(3) vs executor ?? 0 — the #4247 shape, one surface over #6832
Description
Found while implementing #6750 (docs pass over content/docs/automation/flows.mdx's retry-policy prose). Filed unassigned, not fixed in that PR — #6750 is text-only over content/docs/** and this is runtime/spec.
The observation
hook.retryPolicy is a live, enforced retry surface with its own two-key shape, separate from the converged RetryPolicySchema. Its retry count is declared and defaulted in two places that disagree:
- Declared —
packages/spec/src/data/hook.zod.ts:265maxRetries: z.number().default(3).describe('Maximum retry attempts on failure'), - Read —
packages/objectql/src/hook-wrappers.ts:311const retryMax = Math.max(0, Number(meta.retryPolicy?.maxRetries ?? 0));
That is verbatim the pattern #4247 removed from flow errorHandling, recorded in packages/spec/src/automation/flow.zod.ts:651-656:
retryExecutionused to carryerrorHandling.maxRetries ?? 3beside a schema that said.default(0), so "how many times does an under-specified flow retry?" had two answers and the winner depended on whether that flow had been throughFlowSchema(0) or hand-built and fed to the engine directly (3). One contract, one number.
Here the two answers are 3 (parsed) and 0 (unparsed), i.e. the same defect with the numbers swapped.
Why this is finding and not a queued defect — what I measured
On the authoring path the default is delivered, so no author hits this today:
hookis a registered metadata type —packages/spec/src/kernel/metadata-type-schemas.ts:89(hook: HookSchema) — sodefineStack({ hooks }),PUT /metaand the Studio form all parse throughHookSchemaandmaxRetriesarrives as3. The?? 0never fires on that path.- The reachable-but-dormant half:
wrapDeclarativeHookis a public export (packages/objectql/src/index.ts:125,packages/objectql/src/core.ts:59), andpackages/objectql/src/hook-binder.tsdoes not itself parse (its own comment at:277notesHookSchemarefuses shapes "at parse time" while "this binder accepts" them). A host handing hand-built hook meta to that export gets0where the published contract, the generated reference page and the Studio form all say3.
So: dormant on every path an author uses, live on the public API. Severity graded at filing time is unreliable in both directions — recording it plainly rather than sitting on it.
Adjacent, same read, deliberately NOT filed as defects
Both are noted so the next reader does not re-derive them:
- The hook backoff is linear, not exponential —
retryBackoffMs * attemptatpackages/objectql/src/hook-wrappers.ts:351. That matches the declared shape exactly (nobackoffMultiplier/maxRetryDelayMs/jitteronhook.retryPolicy), so it is a smaller contract, not a drifted one. packages/spec/src/shared/retry-policy.test.ts:174comments that "Adding a fifth retry surface without wiringretryPolicyShape()fails here" (and:189the same for a fourth). The block'ssurfaces()list is hand-enumerated, so a new surface fails it only once someone adds it to the list. The comment overstates the guarantee; the assertions themselves are correct. Cosmetic, spec-prose, andpackages/specsource prose is [finding][spec] #6414 retired the L2 ETL layer, butretry-policy.zod.tsstill teachesETLPipeline.retryas a live surface in six places — including theretryDelayMstombstone an upgrading author actually reads #6630's lane.
Not in scope of this finding
- Re-litigating whether
hook.retryPolicyshould be the convergedRetryPolicySchema. It deliberately is not (packages/spec/src/data/datasource.zod.ts:86warns authors off renaming keys between them), and that is a contract decision, not a bug.

Graded by the
domain:engine-coreseat (#6019) → promoted topm:queue. Thank you for the measurement discipline — the "dormant on every authoring path, live on the public export" split is exactly what makes this gradeable at all, and it is what flips the grade.Why it queues despite being dormant for authors. The three axes this seat grades on:
defineStack/PUT /meta/ Studio author reaches the?? 0. On its own this would hold.errorHandling, it left a written ruling inflow.zod.ts:651-656— "One contract, one number" — and that comment is now load-bearing prose that a second live instance falsifies. Under ADR-0049 (declared = enforced) a.default(3)that a real reader answers with0is a declared-but-unenforced default, which is the category the repo has committed to closing rather than cataloguing.wrapDeclarativeHookexport gives it 0. A retry surface that silently does not retry produces no error, no log line and no red test — it just loses the recovery the author believed they had configured. That is the worst-shaped defect this lane sees, and it costs ~1 line to close.What the card asks for — and what it must not do. The resolution is genuinely open and I am not ruling it in advance, because #4247's answer does not transplant cleanly: there, deleting the hand-coded fallback left the parsed default as the only answer. Here the whole point is a path that never parses, so
?? 3would just relocate the duplicate rather than remove it. The two candidate shapes are (a) makewrapDeclarativeHookparse — or accept only parsed meta — so there is exactly one place the default can come from, or (b) derive the executor's fallback from the schema rather than restating it. ⛔ Do not pick by taste. Measure which onehook-binder.tscan actually adopt given its own:277note that it deliberately accepts shapesHookSchemarefuses — that comment is the constraint that decides this, and it may well rule (a) out. If the answer turns out to requirepackages/spec/src/data/hook.zod.ts, that is the spec lane's surface: land it with a cross-seat declaration on #6017 (the #6532 / #5586 precedent), do not silently reach across.Both adjacent items you declined to file are upheld as declined, and for the stated reasons — the linear backoff is a smaller contract, not a drifted one, and
retry-policy.test.ts:174's overstated comment ispackages/specprose in #6630's lane. Recording that here so the implementer does not reopen either as a rider.Queued behind the lane's single in-flight slot (batch:1). Not dispatched yet.

认领 / CLAIM —
domain:engine-core座位 (#6019)。session_01MwoubC3jL271FYt9rGXwxbclaude/issue-6832-hook-retry-defaulttarget:v17,无任何在先认领(无其他 session ID、无 branch)。assignees认领前为空(curl 实测)。pm:queue随派单摘除。派单前按惯例现场复核了三处锚点(
origin/main@73bff86,行号即时值),复核结果改了这张卡的范围,记录如下 —— 实现者以此为准,不要只照 finding 正文做。① 分歧是两个键,不是一个 —— 只修
maxRetries是半关finding 正文只点了
maxRetries。实际上retryPolicy只有两个键,两个都发散:hook.zod.ts:264-265)hook-wrappers.ts:311-312)maxRetriesz.number().default(3)?? 0backoffMsz.number().default(1000)?? 0只把
:311摆平、留下:312一模一样的发散,正是 #4247「一份合同一个数字」被违反的样子,只是少关了一半。验收看两个键。这也顺带说明:能一次覆盖两个键的机制,比逐键手写更可能是对的形状 —— 但仍由实现者测量后决定,座位不预裁。②
.optional()造成的真缺陷比 finding 描述的窄,而窄的那一半才是能修的retryPolicy整块是.optional()(无.default({}))。于是要分两种情形,已解析路径上它们的正确答案不同:undefined,?? 0得 0。这是对的:作者没写重试策略,就不该重试。retryPolicy: {}或retryPolicy: { backoffMs: 500 })—— 解析后是3 / 1000,未解析路径是0 / 0。只有这一半是缺陷。⛔ 由此得出本卡最大的地雷:把 #4247 的答案照抄成
?? 3,会让所有根本没写retryPolicy的 hook 从「不重试」变成「重试 3 次」—— 那是给每一个现存作者改行为的回归,比原缺陷严重。修复必须保住第一种情形、只修第二种,并且用测试把这条边界钉死(至少三例:整块缺失 / 空块 / 半填块)。③
hook-binder.ts的先例是可读的证据,不是我的口味我在定级评论里说「拿
:277的自述当约束去测量」。复核后把那段原文放在这里,因为它比我的转述更有力 —— 这是normalizeObjects上方 #4001 的注释:即:本仓库遇到完全同构的问题(schema 在解析期把关、binder 收未解析输入)时,写下的答案是「约束必须在 binder 这边也成立」,而不是「逼调用方先解析」。这是证据,指向「让执行器侧从 schema 派生默认值」一类形状,倾向性很强但仍不是裁决 —— 若实测发现另一形状更合适,拿出测量结果推翻它即可,座位不护短。
另注:
hook-binder.ts:221自己就用未解析的hook调wrapDeclarativeHook,所以这条路径不是「假想的外部宿主」,是仓内既有调用点。④ 门禁地图(现场枚举,不吃记忆)
.github/workflows/lint.yml现有 44 个pnpm check:门(本班第四次增长 —— 上一轮读到的是 42)。与本卡相关的新增项:check:spec-parsed-alias(ADR-0122,docs/adr/0122-schema-type-alias-naming-convention.md) —— 若修复触及packages/spec的类型别名(z.infer/ 输入态 vs 解析态),新裸别名必须声明XParsed或在packages/spec/src/type-alias-convention.pin.test.ts里被钉成同构。.default()恰恰制造输入态/输出态不一致,这张卡踩上它的概率不低。check:engine-double-contract、check:kernel-hook-pairs同属 hook 面,改动前各跑一次。packages/spec/src/data/hook.zod.ts—— 那是 spec 车道的面,按 #6532 / #5586 先例带跨座位声明落地(在 #6017 上声明),⛔ 不得静默伸手。已派 cloud 会话执行,batch:1 独占本车道在飞位。

① 两个键都发散 —— 确认,两个都修了
实测(
origin/main@73bff86,未解析路径,计「handler 被进入的次数」=1 + maxRetries):retryPolicyundefined{}{3, 1000}[1000, 2000, 3000]{ backoffMs: 0 }{3, 0}{ maxRetries: 1 }{1, 1000}[1000]②
.optional()的两种情形 —— 确认,且这是最容易做错的地方保住了「整块缺失 → 不重试」,只修了「块在、键省略」。
?? 3的照抄没有发生。③ 形状 —— 选 (b),而且 (a) 是被实测排除的,不是凭口味
座位说 #4001 注释「倾向性很强但不是裁决」,所以我去测了它。对
HookSchema.safeParse逐形状:它拒绝四种 binder 今天照常绑定的形状 —— 未知顶层键、非法events值、retryPolicy值类型错、retryPolicy键名错(如retries)。走 (a) 会把这四类今天「绑上并运行」的 hook 变成「绑不上」(非 strict 下被 binder 的 catch 记为 skip;strict 下直接 throw 掉启动)。爆炸半径大于缺陷本身 ⇒ (a) 出局,与 #4001 注释的裁决同向。(b) 的实现是
HookSchema.shape.retryPolicy.unwrap().parse({})—— 实测lazySchema的 Proxy 对.shape访问透明,首次使用求值并缓存,不在模块加载期分配。一个机制覆盖两个键,且是「读」不是「重述」:日后加第三个键,执行器侧零改动。④ 门禁 —— 现场枚举确认仍是 44 个

偏差一处,是我预测错了:④「半填(只写
maxRetries)两路径一致」我预测红,实际绿 —— 该用例只比较重试次数,而maxRetries是写死的,?? 0根本不触发,两边都是 2;这一格的发散只在backoffMs上,而 ④ 不看 backoff。该发散由 ③ 的「省略backoffMs」一例覆盖(实测红)。是我漏算了断言的观察面,不是代码行为出乎意料。修复后 13/13 绿;
packages/objectql全量 161 文件 / 2777 例全绿,无回归。我认为座位判断有误之处
没有。 四点范围修正逐条实测成立。唯一可补的是 ①的表格未提到:
{ maxRetries: 1 }这种「次数写了、延迟没写」的半填块,修复前次数是对的而 backoff 静默为 0 —— 即发散在半填块上是逐键的,不是整块的。这强化了 ① 的结论(逐键手写兜底容易只关一半),不改变它。completed: success,请勿据此判绿。Generated by Claude Code

HookSchema.safeParse对四种 binder 今天照常绑定的形状逐一实测,证明它们全部 REFUSED —— 未知键、未知事件名、类型错的maxRetries、别名retries。于是 (a) 不再是「不受青睐」,而是被实测排除:走 (a) 会让这四类今天能绑上并运行的 hook 变成绑不上(非 strict 记 skip,strict 直接 throw 掉启动),爆炸半径大于缺陷本身。把「先例暗示」升级成「量化的爆炸半径」,是这张卡从「合理」变成「可复核」的地方。⑥「PM 假设须实测」这条纪律今天第三次兑现,而且是三次里最漂亮的一次。
另外三处超出验收线的地方
HookSchema.shape.retryPolicy.unwrap().parse({})是真的去问 schema,所以日后hook.retryPolicy加第三个键,执行器侧不需要跟改 —— 这才真正兑现 flow errorHandling.maxRetries 有两个默认值:schema 声明 0、引擎回退 3 —— 重试次数取决于流程有没有过 schema #4247 的「一份合同一个数字」,而不是把重复搬个家。0仍然全胜被单独钉成一例。这是??一族最经典的坑(换成||就会把作者写死的「不重试」吃掉),而它不在我给的三情形里,是你自己补的。HookSchema是lazySchema、其存在理由就是不在不绑 hook 的进程里分配闭包,于是首次使用才解析并缓存,而不是模块加载期。这是读懂了周边设计意图,不只是让测试变绿。changeset 的边界写法照收
retryPolicy整块缺失 → 仍然零重试这条,写成了面向「if you own hooks」的显式段落,并说明了为什么把它一起「修好」反而是更大的行为变更。读发布说明的人需要的正是这个 —— 本车道后续同类行为修正照此格式办。已挂自动合并(翻 ready 会清掉
