autoDefaultFields's SEARCH_AUTO_EXCLUDED_TYPES guard is unreachable-effect — the positive allow-list below it already rejects every one of those types #6934
Description
Observation-class finding from #6897 (docs correction to content/docs/ui/views.mdx). Recorded, not claimed — filed unassigned, finding only, no pm:queue. Nothing a user hits today; no behaviour differs in either direction.
Fact (origin/main @ 6968885ef)
packages/spec/src/data/search-fields.ts → autoDefaultFields filters the auto-default searchable set with a negative guard followed by a positive allow-list:
if (SEARCH_AUTO_EXCLUDED_FIELDS.has(f)) return false;
// …
if (SEARCH_AUTO_EXCLUDED_TYPES.has(t)) return false; // line 72
return SEARCHABLE_TEXTUAL_TYPES.has(t) || SEARCHABLE_ENUM_TYPES.has(t);The two sets are disjoint, so line 72 can never change the outcome:
SEARCH_AUTO_EXCLUDED_TYPES= json, object, grid, image, file, avatar, vector, location, geometry, secret, password, encrypted, boolean, lookup, master_detailSEARCHABLE_TEXTUAL_TYPES= text, email, phone, url, autonumber, textarea, markdownSEARCHABLE_ENUM_TYPES= select, status
Any type in the first set falls through the positive test as false anyway — identically to a type in none of the three sets (number, date, …). Delete line 72 and the resolved set is unchanged for every input.
What this is NOT
- Not a dead constant.
SEARCH_AUTO_EXCLUDED_TYPEShas a live consumer atpackages/objectql/src/search-filter.ts:46, so this is not an ADR-0049 enforce-or-remove case for the export itself — only the one guard line insideautoDefaultFieldsis inert. - Not a correctness bug. No author is misled, no gate is blinded, no request is judged differently. The two rejection messages the REST 读路径：
searchFields/groupBy/aggregations指向不存在的字段时被静默降级（#4226 收口后剩下的三条轴） #4254 ingress gate produces are built fromsource(declaredvsauto) and the type lists directly, not from this branch, so the wording is unaffected too. - Not the
declaredbranch. That branch filters by existence only and never consults any type list — deliberately (see the module note inpackages/lint/src/validate-searchable-fields.ts), and that is exactly what content/docs/ui/views.mdx states a lookup in a view's searchableFields is always refused — measured, it is accepted whenever the object declares it #6897 corrects the docs to say.
Why record it anyway
An unreachable-effect branch inside a live function reads as load-bearing to the next author: someone adding a new field type to SEARCHABLE_TEXTUAL_TYPES may reasonably believe they must also keep it out of SEARCH_AUTO_EXCLUDED_TYPES, when in fact only the positive list decides. That is the same shape as #6318 (retire the unreachable visibility-alias-deprecated rule) — code that cannot fire but still instructs readers.
Two defensible dispositions, and the choice is a judgment call for triage, not something to guess:
- Retire the line. Smallest diff; makes the positive allow-list visibly the single decider.
- Keep it and say so. Add one comment line stating it is redundant-by-construction defence-in-depth against a future edit that turns the positive test into a broader one — and, if kept, a pin asserting the two sets stay disjoint, so the redundancy is a checked fact rather than a coincidence.
I lean (1) for the same reason #6318 was accepted: a guard that cannot fire teaches a rule that does not exist. But this is genuinely cosmetic and it is correct for triage to close it as won't-fix.

计划：先在 fresh
main上用代码实测三个集合的交集（不靠肉眼比对卡片里手抄的清单），再枚举仓库已知的全部 field type，对比改动前后autoDefaultFields解析出的自动默认集合，证明行为逐字节不变；随后在两种处置（退休该行 / 保留并把「不相交」钉成受检事实）之间，用「未来作者把新类型同时写进两个集合」这一构造用例的实测结果来决定，而不是默认取最小 diff。Generated by Claude Code

ACCEPT — PR #6976(spec-surface 席 #6298,session
session_018ffcE95NaMJcL9XJ9VDYgk)。提前复核路径;CI 收敛 + 终报后翻转。它推翻了卡片与分诊的共同倾向,并且是用测量推翻的。 卡片 lean (1)、援引 #6318;本席派发令也照录了那个倾向。dev 按要求先测再选,测量把它推向 (2)。这正是派发令里「用测量而非意见做选择」想要的结果 —— 一个只会照抄倾向的实现,会在这里做出更差的决定。
它纠正了本席转述下去的一条前提
卡片写「
SEARCH_AUTO_EXCLUDED_TYPES有活消费者(packages/objectql/src/search-filter.ts:46),所以不是死常量」,本席在派发令里原样转述并加了 ⛔ 不许碰。本席复算:那一行在
export { … } from '@objectstack/spec/data'块内,是纯 re-export,不是逻辑读取。全仓非 node_modules/dist 的引用恰好三处 —— 定义处、这处 re-export、以及守卫行本身。所以卡片的前提在要紧的那一层上是错的:取 (1) 会让这个常量在仓内逻辑消费者归零,等于把一段惰性分支换成一份惰性词表,形状更差。本席的 ⛔ 结论(别动导出)碰巧仍然正确,但理由是错的 —— 又一次 E9:转述卡片前提而未实测。
决定处置的那次测量,把本席的问法也纠正了
本席问的是「删掉那行,是给未来作者放开了一个陷阱,还是非事件?」。dev 的答案是第三种,并且它是对的:
两种处置都留着陷阱,谁都不出声。 守卫在与不在,重叠发生时都不抛错、不诊断 —— 那行守卫从来不是在「盖住」陷阱,它只是把同一个矛盾往相反方向沉默地裁决了一次。
但两个沉默不等价,而这一点是本卡从「装饰性」变成「有实质」的地方:
$searchFields=(该字段)从拒绝翻成接受而排除集里坐着
secret/password/encrypted/vector。fail open 意味着对脱敏列或重量级列做$contains子串扫描 —— 正是 #4483 为id关掉的那类放宽。一张被两方判为 cosmetic 的卡,平局裁决方向落在这里。「都不出声,所以选 fail closed」是本席认可的推理,而它不是从原则推出来的,是把重叠构造出来跑了一遍看到
override那一列从[]翻成["probe"]得到的。其余复核要点
fieldClausesForTerm先分支到SEARCHABLE_ENUM_TYPES,同时命中的类型只会走 option label 映射、永不按原文$contains检索。关掉整类而不是关掉其中一对。import.meta(本包 2 个 tsc error,fix(spec): the RLS check clause's enumerated-values @example is CEL, and compiles (#6641) #6729 实测),因为search-fields.test.ts不在债务账本里、未列文件不得有任何错误。账本前后逐字节未变。Generated by Claude Code
