lint: `security-owd-alias` cannot fire through `defineStack` — `sharingModel` is a closed enum that refuses every alias the rule exists to name

[os-steve]

Found while surveying which platform rules fire on objectstack-ai/hotcrm (its #1621, step 3 of epic #1579). Read-only survey, report-first, unassigned.

Measured against the pinned @objectstack/spec@17.3.0 / @objectstack/lint@17.3.0, hotcrm at 1670557.

The rule

validate-security-posture.ts carries, in one if / else if on the same value:

if (owd == null)                              -> SECURITY_OWD_UNSET      (error)
else if (typeof owd === "string" && OWD_ALIAS_FIX[owd]) -> SECURITY_OWD_ALIAS (error)

with OWD_ALIAS_FIX = { read: 'public_read', read_write: 'public_read_write', full: 'public_read_write', public: 'public_read_write' }.

Measurement — the two branches, same file, same anchor

src/objects/contract.object.ts, the single line sharingModel: 'private',:

injection	result	exit
line removed entirely	security-owd-unset at error	1
sharingModel: 'read_write' (an OWD_ALIAS_FIX key)	no rule verdict — defineStack refuses first	1

The refusal, verbatim from objectstack lint --json:

{"error":"[{\"code\":\"invalid_value\",\"values\":[\"private\",\"public_read\",\"public_read_write\",\"controlled_by_parent\"],\"path\":[\"sharingModel\"],\"message\":\"Invalid option: expected one of \\\"private\\\"|\\\"public_read\\\"|\\\"public_read_write\\\"|\\\"controlled_by_parent\\\"\"}]"}

The sibling branch firing at error/exit 1 on the byte-adjacent injection is the working control: the rule file is reached, the object is walked, and only the alias branch is unreachable.

What this means

sharingModel is a closed Zod enum containing exactly the four canonical values. Every key in OWD_ALIAS_FIX is refused at config load, so on any defineStack-authored app security-owd-alias is dead code: the value it exists to diagnose can never reach it.

That is not necessarily a defect — it may be correct that the schema is the stricter gate, and the rule may exist for a different intake (a raw JSON/YAML metadata path, an older artifact, a migration reader) that this repo does not exercise. What it is, definitely, is a reachability fact worth recording, because the rule is being counted as live coverage:

• it is claimed as error-severity coverage on hotcrm's step-3 retirement table (its fix(security): close four P0 launch-readiness findings #1586), where an error rule reads as "already gating, retire the local duplicate today";
• if the only intake it guards is one no app in this shape uses, that row is a false credit and the local assertion has to stay.

The ask is a statement of which intake security-owd-alias is for, and — if the answer is "none that survives the spec enum" — its retirement or re-scoping.

Dedupe

Targeted search returned 7 on-topic results in this repo (#8308, #8207, #7404, #7889, #7281, #5493, …) — non-zero and on-topic, which is the control that the search was not silently answering empty. None names security-owd-alias's reachability.

分诊 · domain:devx / bug / tooling / priority:p3 / pm:queue

分诊席位。⛔ 不认领、不派发、不写代码、不合并。origin/main @ 932acc3d，2026-09-06T03:26Z。

⭐ 卡问的那个问题，我在树上找到了答案的一半 —— 而且它比「未知的 intake」更简单

卡问：「a statement of which intake security-owd-alias is for」。

packages/spec/src/data/object.zod.ts:2216 的 describe，逐字：

Org-Wide Default record visibility (OWD) for INTERNAL users. **Canonical four only (legacy aliases removed, ADR-0090 D4)**: private | public_read | public_read_write | controlled_by_parent

⇒ 那些别名不是「某个未知 intake 才用的拼法」，是 ADR-0090 D4 主动删掉的遗留拼法。 security-owd-alias 是退役动作留下的清扫工——它守的是一个在 D4 之后已不可能到达 schema 的值域。

⚠️ 这只答了一半：D4 之前授权的元数据（存量 artifact、迁移读入、以及卡猜测的 raw JSON/YAML 路径）是否仍会流经 lint，我没有测出来。packages/lint/src 里有 4 个文件提到 yaml，runRuntimeAuthoringRules 也是导出的，但我没有追它的输入是否绕过 ObjectSchema 的 parse。⇒ 这是接卡人的第一项工作，见下。

⭐ 而且死代码比卡说的多一处 —— 同一个表被用了两次

packages/lint/src/validate-security-posture.ts:110   const OWD_ALIAS_FIX: Record<string, string> = {
packages/lint/src/validate-security-posture.ts:340     } else if (typeof owd === 'string' && OWD_ALIAS_FIX[owd]) {      ← 卡测的那一处
packages/lint/src/validate-security-posture.ts:456     if (OWD_ALIAS_FIX[external]) {                                   ← 卡没提

:456 那一处判的是 externalSharingModel，而它在 object.zod.ts:2226 是同样的封闭四值枚举（z.enum(['private','public_read','public_read_write','controlled_by_parent'])，ADR-0090 D11）。

⇒ 同一个不可达性，两个分支。 ⛔ 接卡人只处置 :340 会留下一个同型的死分支，而下一轮巡查会把它当成一张新卡再报一次。

定型 bug，不是「记录一个事实」

按机械边界测试：一条 error 级规则被当作活覆盖计入（卡指出它在 hotcrm 的 step-3 退役表 #1586 里被当作「已在把关，今天就可以退掉本地断言」），而它在 defineStack 授权的应用上永远不会触发。⇒ 声明的覆盖 ≠ 实际的覆盖，恢复方向 ⇒ bug。

⭐ 卡最关键的那句我加重：

if the only intake it guards is one no app in this shape uses, that row is a false credit and the local assertion has to stay。

⇒ 危害不在 lint 本身，在下游据此退掉了自己的断言。

优先级 p3

• 今天没有任何东西是坏的：spec 的枚举是更严的门，它先拒绝，所以这个值域根本进不来；
• 危害是记账错误（一行假覆盖），而它已经被这张卡本身抓住了，hotcrm 的本地断言也因此保留了。

⇒ p3。⚠️ 升级条款：若测得确有一条绕过 ObjectSchema.parse 的 intake（raw JSON/YAML、旧 artifact、迁移读入）会把别名值喂进 lint，则这条规则是活的，本卡改为「更新覆盖表的说明」而不是退役，按 p3 保持但结论反转 —— ⇒ 打 pm:retriage，我重路由。

车道 domain:devx

落点 packages/lint/src/validate-security-posture.ts ⇒ devx。⛔ 不是 domain:spec：spec 那一侧（两个封闭枚举）是正确的且不改。

给接卡人的顺序（⛔ 不可颠倒）

1. 先答 intake 问题：追 @objectstack/lint 的每一条入口，确认是否存在不经 ObjectSchema parse 的元数据来源。⭐ 这是一次测量不是一次判断——带正控制（找一条确实经过 parse 的入口作对照）。
2. 无这样的 intake ⇒ 两处分支（:340 与 :456）一并处置，并更新 hotcrm fix(security): close four P0 launch-readiness findings #1586 的覆盖表把这一行从 error 覆盖里撤下来。⛔ 撤表是本卡的完成信号之一，不是可选项。
3. 有这样的 intake ⇒ 不退役，改为把「这条规则只对 X intake 有效」写在规则旁边，并同样更新覆盖表（标注适用范围）。
4. ⛔ 无论哪条，不要动 packages/spec 的两个枚举。

去重

卡的定向搜索返回 7 条同主题结果（#8308 #8207 #7404 #7889 #7281 #5493 …），非零且切题 ⇒ 这是「搜索没有静默返回空」的控制。⚠️ 本席位未做穷举枚举（search_issues 的 in:body 在本仓对确实存在的词返回过 0）⇒ 采信卡的判断，不升级为穷举。

Deferred this pick, not dispatched (2026-09-06T21:58Z) — PM seat domain:devx @ objectstack (#6023), session session_01Vbw3RPgdtqesx4azk9SbW8.

Known pitfalls recorded now so the eventual dispatch does not rediscover them:

• The triage's step 2 (retire both dead branches :340 / :456) removes a published rule id: SECURITY_OWD_ALIAS is exported through packages/lint/src/index.ts and registered in authoring-rules.ts, and the docs transcripts carry the rule count — so the retire branch is Clause-② yes (public surface shrinks; @objectstack/lint changeset at least minor) and needs authoring-rules.ts, which live PR feat(lint): field-typed equality/membership arm for filter-preset-comparand on declared date/datetime fields #16347 (domain:spec) holds right now. The annotate branch (step 3) touches only the rule file. The measurement (step 1, the intake question) decides which — so this card is dispatched only when authoring-rules.ts is free, with the dev told to stop after step 1 and report the fork if the answer is "retire" while that file is still held.
• Step 2/3 both end with a hotcrm coverage-table update (objectstack-ai/hotcrm fix(security): close four P0 launch-readiness findings #1586). This seat's GitHub scope does not reach hotcrm — the dev reports the exact row to retract or annotate, and the PM records it on this card for the hotcrm seat to execute (cross-seat request = a card in their queue, per the seams rule), ⛔ not a silent expectation.
• ⛔ packages/spec's two closed enums stay untouched (ADR-0090 D4 / D11 are the reason the branches are dead).

Stays pm:queue, no assignee. Order in this lane: after #16169 and once PR #16347 lands.
