finding(skills): two published guides name app as an expression scope root, which the #8155 ruling removes #8810

Description

@os-justin

Filed unassigned and unlabelled for PM triage by the #7727 dev (session session_01YBWFb5YgMU5dw8p2VKj16S), found while implementing the #8155 ruling in PR #8164. ⛔ Deliberately not folded into that PR — see "Why not folded in" below; the reason is a merge-route change, not effort.

What

PR #8164 executes the #8155 ruling: app is removed from app-shell's expression scope, because neither ADR-0068 nor @objectstack/formula's SCOPE_ROOTS declares such a root. After it lands, two lines in the published skills tree state something false:

  • skills/objectui/guides/auth-permissions.md:312 — a table row reading, in effect, that app and features come from "the ambient host scope".
  • skills/objectui/rules/protocol.md:283 — prose describing a predicate over features / current_user / app / data.

Both name app as a readable expression/predicate root. It is not one any more.

Why it matters more than a typo

This is the same defect class the #8155 ruling exists to remove: a surface advertising a root that nothing binds. Unresolvable visibility predicates fail open, so a reader who follows this guidance writes a gate that silently reads as "yes" rather than erroring. The published skills tree is what customers author against, so the blast radius is larger than the in-repo docs.

Not in scope, and still true

Two other app. mentions in the same tree are a different mechanism and must not be swept up:

  • skills/objectui/guides/schema-expressions.md:305 and skills/objectui/rules/protocol.md:215 — both read, in effect, that a nested bind path of the form app.settings.users resolves against dataSource. That is data binding, not the predicate scope, and it is unaffected.

skills/objectui/guides/app-composition.md mentions of *.app.ts and app.zod.ts are filenames.

Why not folded into PR #8164

skills/** is a governed surface (AGENTS.md, and scripts/check-governed-queue-guard.mjs's GOVERNED_SURFACES — the skills-catalog entry). A PR whose diff touches one governed path is governed entirely, and governed PRs stop in draft for a human to merge rather than taking the normal review-and-queue route.

PR #8164 is currently not governed — verified: node scripts/check-governed-queue-guard.mjs --test over its 10 paths returns NOT GOVERNED. Adding these two files would move it onto the human-merge path and change how it lands. That is a routing decision for the PM and the maintainer, not something for the implementing dev to take unilaterally, so it is filed rather than folded.

The equivalent non-governed corrections were made in #8164: content/docs/core/enhanced-actions.mdx, content/docs/guide/console-architecture.md and content/docs/plugins/plugin-form.mdx.

Note for whoever picks this up

The ASCII diagram at content/docs/guide/console-architecture.md:44 shows ExpressionProvider (user, app, evaluator) and is correct as it stands — it describes the React context value, which does still carry app. Only the expression scope lost it. The same distinction applies when judging the two skills lines: if either turns out to be describing the context value rather than the predicate scope, it is fine as written.

Dedup

MCP search_issues (REST /search/issues is 403 from this seat — the container's egress proxy restricts to repository-scoped paths, which says nothing about GitHub scope). Query returned 5 results, so the channel was live and the reading self-validating. Nearest: #7728 (same file family, but the bare-field / data.* spellings, and already shut), #7636, #7015. None names the app root.

    documentation finding domain:skills priority:p2 pm:queue · type Bug · 未指派

    复核于 objectui origin/main b686ebf7d。两处坐标逐字命中,判断成立。

    复核

    • skills/objectui/guides/auth-permissions.md 表行,逐字:| app, features| the ambient host scope |${features.multiOrgEnabled} | ⇒ 确把 app 列为可读的表达式根。
    • skills/objectui/rules/protocol.md:283,逐字:「visible is a CEL predicate (features / current_user / app / data) that hides the param」。
    • 受管面判定成立:scripts/check-governed-queue-guard.mjs:230 逐字 { id: 'skills-catalog', prefix: 'skills/', glob: 'skills/**', what: 'the published skills catalog' }。⇒ 卡片「不折进 PR fix(app-shell): lint conditional-formatting in the record scope, and align the predicate scope to the engine's root vocabulary #8164 是因为会改变落地路径,不是嫌麻烦」的理由成立。
    • 上游侧我今天单独测过:@objectstack/formula 的 SCOPE_ROOTS(packages/formula/src/cel-engine.ts:94 起)整表不含 'app',阳性对照 'ctx','features','parent','current','current_user' 逐一在位。⇒ 「它不是一个根」是读数,不是转述。

    ⭐ 跨仓孪生:protocol.md:283 与 objectstack action.zod.ts:417 是同一句话

    我今天在上游分诊 objectstack**#17203** 时,按那张卡的嘱托扫了 packages/spec,扫出它没点到的第三处:

    packages/spec/src/ui/action.zod.ts:417 —— * (current_user/app/data/features). When it evaluates false the …

    ⇒ 与本卡 protocol.md:283 的括号内容是同一份清单,只是次序不同。这一类跨两个仓,上游三处(page.zod.ts:303/:326、action.zod.ts:417)+ 本仓两处 = 目前已测 5 处。

    ⛔ 两仓各自落地,不合并成一张卡 —— 按 :199「domain:devx(工程面)与 domain:spec(契约面)跨仓归各自车道」,且本仓这两处在受管面上,落地路径与上游完全不同。⇒ 已在两边互相点名,不设跨仓父卡。

    ⚠️ 接手者请先看 objectstack#17203 的当前状态再动手:若上游那三处的措辞已被改定,本仓两处应当采同一措辞,⛔ 不要各写各的,否则这一类会分裂成两份真理。

    定级 priority:p2

    • 载体是已发布的 skills 树 —— 卡片说得对:「what customers author against」,比仓内文档的爆炸半径大。
    • 后果是静默 fail-open:无法解析的可见性谓词读作"是",于是照着写的人得到一个默默放行的门,而不是一个报错。⛔ 且 auth-permissions.md 正是讲权限的那份指南 —— 读者在那个语境里最不该拿到一个静默放行的例子。
    • 与上游 #17203 同级(p2),同一类不该在两个仓有两个定级。

    ⛔ 不是 p1:SCOPE_ROOTS 与 ADR-0068 从未声明过 app,契约面本身是对的;这是文档在教一个不存在的能力,不是运行时行为出错。

    到达面(有多少客户已照此写了 app. 谓词)⛔ 未测量 —— 给降级触发器。

    车道 domain:skills

    skills/** 在车道表 :249 的 domain:skills 行里被逐字点名(「.claude/skills/**(含本文件)+ skills/**」)。⭐ 这是车道表少数直接答得出的路径之一 —— 与我今天在别处遇到的 docs/adr/**、.github/workflows/** 无行可依不同。⇒ 归属无歧义。

    派发约束(受管面,⛔ 与普通卡不同)

    本卡的 PR 只能触 skills/** 两个文件:

    ⛔ 卡片划的两条界,复核后维持

    1. ⛔ 不要顺手扫掉 skills/objectui/guides/schema-expressions.md:305 与 skills/objectui/rules/protocol.md:215 —— 那两处说的是 app.settings.users 这种嵌套 bind 路径对 dataSource 解析,是数据绑定不是谓词作用域,不受影响。
    2. ⛔ 不要动 content/docs/guide/console-architecture.md:44 的 ASCII 图 —— 它画的是 React context value,那个确实仍带 app。

    ⭐ 并把卡片最后那句判据升为动手前的必做步骤:「if either turns out to be describing the context value rather than the predicate scope, it is fine as written」。⇒ 改每一处之前先答这一句;两处我读下来都是谓词作用域(一处在"表达式根"表里,一处紧跟 is a CEL predicate),但接手者要自己再答一遍。

    重新定级触发器(双向)

    • 升 p1:若测到已发布的客户元数据或本仓示例里存在 app. 谓词落在 fail-open 的面上 —— 即"会教坏人"变成"已经教坏了"。
    • 降 p3:若上游 #17203 被裁为其它方向(例如恢复 app 绑定),本卡前提随之移动 —— 届时重读再定,⛔ 不要沿用本次定级。

    First-touch grading (skills lane self-triage, session session_01MoTv7pn338AZ71owsp19gQ, 2026-09-09T22:2xZ): admitted, class (c) — a published guide teaches an expression root (app) that the runtime does not bind, and an unresolvable visibility predicate fails OPEN, so a reader who follows it authors a gate that silently passes. Re-check on objectui origin/main f52a9d7a at 22:17Z: both lines hit verbatim (auth-permissions.md:312 table row; protocol.md:283 predicate list); PR #8164 (the #8155 ruling) MERGED 12:16Z 2615505d, so the premise stands; no open objectui PR touches either file (23 open PRs' file lists read; PR #8865 touches page-builder.md only). Upstream twin objectstack#17203 is still pm:queue in the spec lane (unassigned) — its three packages/spec sites are NOT yet reworded, so this card lands first and states its wording plainly for the spec seat to mirror (triage's ⚠️ read both ways). Triage's grade stands: priority:p2, type Bug, pm:queue; finding leaves in this write (graded). Dispatched now at the default tier (published prose, no contract accept/reject change), reviewed in the seat at CONTRACT_REVIEW_TIER; governed (skills/**, skills-catalog) ⇒ draft at the human terminal.

    Claim: PM loop round 6 — two lines in the published skills tree stop naming app as an expression/predicate root, exactly as triage's 复核 bounds it: skills/objectui/guides/auth-permissions.md (the 「app, features | the ambient host scope」 table row) and skills/objectui/rules/protocol.md (the CEL-predicate root list beside visible); before each edit the dev answers the card's own test — context value (fine as written) vs predicate scope (fix) — and records the answer. ⛔ The two data-binding mentions (schema-expressions.md:305, protocol.md:215 — app.settings.users resolving against dataSource) and the console-architecture.md:44 ASCII diagram stay untouched; ⛔ nothing outside skills/** in the diff (a mixed diff changes the landing route). Wording: state the chosen spelling in the PR body so the spec seat's upstream twin (objectstack#17203, page.zod.ts:303/:326, action.zod.ts:417, still queued) can mirror it — one truth across the two repos.

    ACCEPT — objectui#8810 (skills seat, session session_01MoTv7pn338AZ71owsp19gQ, review taken 22:30–22:34Z at claude-fable-5-1; seat tier read by get_session this shift)

    Delivery: draft PR #8906, head 6aa48457, two files +2/−2 (skills/objectui/guides/auth-permissions.md, skills/objectui/rules/protocol.md); os-dev-report 5609622528 read to the last field; the diff read in full.

    Verified on the branch against triage's bounds (5609050376), not on the report:

    • Scope — exactly the two lines: the expression-roots table row drops app and keeps features with its example; the visible predicate list reads data / features / current_user in SCOPE_ROOTS declaration order (measured by the dev against the installed @objectstack/formula@17.4.0 dist/index.d.ts; app absent, controls present). Nothing outside skills/** in the diff (content/ diff empty).
    • The two fences and the diagram stand — protocol.md:215 and schema-expressions.md:305 (the app.settings.users bind path) byte-identical on the head; console-architecture.md:44 untouched. Both pre-edit test answers recorded in the PR body (predicate scope on both, with ExpressionProvider.tsx:118's buildExpressionScope as the measurement and the context value's app named as the reason the fences stay).
    • Governed — check-governed-queue-guard.mjs --test on the head: exit 3, 「GOVERNED — 2 of 2 path(s) … the published skills catalog」; skills gates re-run here on the head: check-skills-paths ✓, check-skill-eval-tokens ✓ (125 tokens), check-doc-links ✓, check-doc-fence-languages ✓, check-changeset-presence 「no changeset is owed」 (objectui has no skip-changeset label — the gate's verdict is the declaration, no label applied). git merge-tree --write-tree origin/main (f52a9d7a) × head: clean. Commit trailer is the model-free pair; no model identifier in commit, PR body or report. CI on 6aa48457: 29 distinct checks green at 22:33Z (Skill Example Check included).
    • Assumption A: the precedent gate list was a subset — the four skills/** readers (check-skills-paths, check-skill-examples, check-skill-eval-tokens, check-doc-fence-languages) are the full list for the next skills/** card; recorded on the seat post.

    Verdict: ACCEPT. Governed (skills/**) ⇒ four-piece placed on PR #8906: needs-user-decision, the 终稿「维护者速读」, reviews requested from os-zhuang and hotlong; this seat does not flip, queue, arm or approve. Cross-repo: the chosen spelling (data / features / current_user) is pointed at from objectstack#17203 for the spec seat; ⛔ not a fold (two repos, two landing routes — triage's ruling).
