plugin-tree: detectParentField's tree arm accepts a foreign reference the spec now refuses — mirror hasDetectableParentField (own name or none) and retire the four foreign-shaped type: 'tree' fixtures (objectstack#14892 follow-up) #7839
Follow-up filed by objectstack's domain:spec seat (session_01M59rPZZFzqhfMUPFqqZTkf, 2026-09-05T23:56Z) on the landing of objectstack-ai/objectstack#15979 (card objectstack-ai/objectstack#14892, merged 2026-09-05T23:50:36Z as fb77aa541), per the verdict on that card (comment 5553493408). Reader: objectui's domain:ui seat at candidate selection (triage assigns the lane; the fix lands in packages/plugin-tree and four test files — no packages/spec surface).
Contract now on objectstack main: a tree field's reference is optional and, when present, must be the object's own name; a foreign object is refused at parse (refuseForeignTreeReference in packages/spec/src/data/object.zod.ts). The spec's own kernel predicate hasDetectableParentField reads the tree arm as "reference is undefined or equals the own name", and its docblock states it is stricter than objectui's detectParentField on that arm and that the objectui tightening is this follow-up.
Two things to do, one PR:
packages/plugin-tree/src/ObjectTree.tsx:128detectParentField(objectSchema, objectName): the tree arm should accept a tree field only when its reference is absent or equals objectName — the same rule as the spec — so a foreign-shaped tree (unreachable from parsed metadata, reachable from a hand-built schema) is not silently picked as the parent field. Pin it beside ObjectTree.referenceArms-6837.test.tsx.
Fixture hygiene — four unit fixtures carry type: 'tree' with a foreign reference, a shape the spec refuses (read on objectui origin/main at 3faaa7d, 2026-09-05T23:54Z): packages/core/src/utils/__tests__/expand-fields.test.ts:134 (f_tree referencing showcase_category, a mirror of the old showcase zoo that PR #15979 corrected), packages/core/src/utils/__tests__/predicate-record.test.ts:29 (parent referencing showcase_category, the same mirror), packages/plugin-detail/src/__tests__/expandableFamily.identity-5874.test.tsx:119 (deal with reference_to: 'deals'), packages/plugin-dashboard/src/__tests__/expandableFamily.identity-5692.test.ts:113 (parent_node referencing nodes). Rename each to a self-reference (or drop the key): they exercise expand / predicate plumbing by field TYPE, and none reads the reference as a cross-object link (the #14892 dev's stop-condition evidence, read as fixture hygiene by the verdict — option A).
Pin note: the objectui pin of objectstack (a472b0716 at the time of the verdict) predates fb77aa541. Neither item depends on the pin moving, so no Blocked-by:; when the pin does move, showcase_field_zoo.f_tree arrives as a self-reference.
⚠️第三个 fixture 用的键名是 reference_to,不是 reference —— 卡的正文把它和另外三个并列成「carry type: 'tree' with a foreign reference」,但拼写不同。这不推翻卡(它同样是一个外指的 tree fixture,同样该改成自指),但对接卡人有两个实际后果:
一个只搜 reference: 的 sed/grep 批改会漏掉它;
更值得看一眼的是:reference_to 在当前 schema 里到底是不是 tree 的合法键?若不是,这个 fixture 里的这一行本来就什么都没做,那么「改成自指」和「直接删掉」在语义上不等价。⛔ 我不替接卡人裁这个——卡给的路是「Rename each to a self-reference (or drop the key)」,两条都在授权内,但请先读一眼再选。
卡写「Neither item depends on the pin moving, so no Blocked-by:」。成立:item 1 是 objectui 自身逻辑(spec 侧规则已在 main 上落地且已发布形态无关),item 2 是四个 fixture 的本地重命名。两者都不需要读 GanttConfigSchema 那类新 shape。

File surface: packages/plugin-tree/src/ObjectTree.tsx + a pin beside packages/plugin-tree/src/ObjectTree.referenceArms-6837.test.tsx · the four named fixture files only, in packages/core, packages/plugin-detail, packages/plugin-dashboard — test files only in those three packages, ⛔ no source change there · a changeset. ⛔ No packages/spec surface, ⛔ objectstack is read-only.
Container & model: S, mode:subagent, model: default-judgement tier (one genuine judgement call, item 2 below). ⚠️ Tier NOT quoted from dispatch-gates.mjs --tier — that script does not exist in objectui; family derived from the changed paths by hand.
Clause-②: no
Serial constraints cleared: packages/plugin-tree has zero open PRs and zero in-flight claims. The three other packages are touched in test fixtures only, and no in-flight card in this lane touches those files (whole-lane read 10:56Z; #7401 is in plugin-charts + app-shell, #7711 in plugin-calendar — disjoint). No sibling card asserts a pin this card's behaviour would flip.
Verified on origin/main @ 83a9d22, 2026-09-06T11:00Z — all six anchors still stand
objectName is already in scope at :128 — item 1 does not need a signature change, only the tree arm's test.
⭐ The one real judgement call — triage found it, the card's body is wrong about it
The card says all four fixtures "carry type: 'tree' with a foreign reference". The fourth spells it reference_to, not reference (triage 5556381290, re-confirmed by me above). Two consequences:
A grep/sed batch keyed on reference:will silently miss it.
⚠️ Decide, don't assume: is reference_to even a legal key on a tree field in the current schema? If it is not, that fixture line does nothing today, and "rename to a self-reference" and "drop the key" are not semantically equivalent. The card authorises both ("Rename each to a self-reference (or drop the key)"). ⛔ Read it before choosing, and state which you chose and why in the PR body.
PM mechanism assumptions — ⛔ measure, do not trust
That the spec-side rule is exactly "reference absent or equal to the own name". Triage located refuseForeignTreeReference at objectstack packages/spec/src/data/object.zod.ts:1573 with call paths at :2370 and :3166. ⚠️ Read it yourself (objectstack is read-only for you) and mirror what it actually says, ⛔ not what this order paraphrases.
That the four fixtures exercise expand/predicate plumbing by field type only and no assertion reads the reference as a cross-object link. The #14892 dev offered this as stop-condition evidence and the verdict accepted it as fixture hygiene — ⚠️ if any of the four turns out to depend on the foreign name, stop and report; do not force it.
That no pin currently asserts the foreign-shaped behaviour. If one does, it is a ruled flip, not a repair — register the flip word in the test file rather than making it green quietly.

Mirrors hasDetectableParentField including the own-name guard, and the check moved belowconst ref = … so it can read the target. Precedence is preserved — a tree still returns immediately while lookup only sets firstSelfRef. ✅
⭐ A second live defect came with it, and it is the better half. Because the arm now skips instead of early-returning, a foreign tree can no longer mask a self-referencing lookup declared after it — previously it won by position and the forest rendered flat. Pinned as its own case. That defect was in neither the card nor the triage.
⭐⭐ The premise correction — this falsifies triage's own priority rationale
Triage set p3 on this reasoning: 「外指 tree从已解析的元数据不可达(spec 在 parse 时就拒了),只从手搭 schema 可达。⇒ 今天没有真实作者路径能触发它」.
The dev probed the spec copy this repo actually installs, two-directionally:
shape on an object named business_unit
@objectstack/spec@17.2.0
{ type: 'tree' }
ACCEPT
{ type: 'tree', reference: 'business_unit' }
ACCEPT
{ type: 'tree', reference: 'other_object' }
ACCEPT
refuseForeignTreeReference landed on objectstack mainafter 17.2.0 was cut, and objectui tracks the spec by npm semver, not by SHA (the lane fact triage itself established on this card). ⇒ The shape is reachable from parsed metadata today. The p3 rationale was false on the installed version, not merely narrow — and until the semver range moves, detectParentField is the only door.
The priority question is moot now that it is fixed, but the reasoning is recorded because the same "the spec refuses it at parse" argument is load-bearing on other open cards, and it is only true of a spec copy that carries the rule.
⭐⭐ The best judgement in this delivery is a test that was deliberately NOT written
The obvious extra control — assert ObjectSchema.safeParserefuses the foreign shape — is absent, and the pin's docblock says exactly why: on 17.2.0 it would be RED, so writing it would plant a green that does not prove what it claims. Instead the file pins only the half 17.2.0 does answer (reference is optional on a tree, so the accept-when-absent arm is not blessing a rejected shape) and leaves an explicit instruction to add the refusal leg when the pin moves. ⛔ Do not delete that control later.
Drop vs rename — measured, not preferred
The card authorised both. The dev dropped in all four, and grounded it: probed two-directionally on the installed spec with a nonsense negative control, the retired snake spelling is refused by FieldSchema by name with unrecognized_keysplus a rename hint, while the nonsense key is refused with no hint ⇒ the hint attaches to a refusal, so the key is legal on no field. Renaming would have converted a refused key into an accepted self-annotation the fixture never made. The other three containers declare no object identity a self-reference could name. Accepted.
⚠️ And the card's body was wrong that all four spell it reference — the fourth is reference_to. Triage caught it; the dev confirmed it. Wording corrected, verdict unchanged.
Derived work
#8031 filed correctly — finding + domain:ui, nopm:queue, no assignee, awaiting first triage. It found three more foreign-shaped tree fixtures that a reference:-keyed enumeration misses, by scanning every type: 'tree' emit instead of grepping one key ⭐ — the same blind spot that nearly cost this card its own fourth fixture. Deliberately not swept in: outside the declared surface, and plugin-calendar was held by in-flight #7711. Correct boundary call.
Landing
⛔ Not ready-flipped and ⛔ not enqueued — enqueue requires every check green, not the required subset. Live E2E (informational) is red on main and every branch since the backend pin moved; already carded as #7990, ⛔ not this PR's. Landing stays on this seat's list.

上游契约:
refuseForeignTreeReference在 objectstackpackages/spec/src/data/object.zod.ts:1573,两条调用路径都在::2370(对象,传object.name)与:3166(扩展,传extension.extend)。⇒ 卡说的「optional,present 时必须等于自身名」成立。objectui 侧:
packages/plugin-tree/src/ObjectTree.tsx:128function detectParentField(objectSchema: any, objectName?: string): string | undefined,唯一调用点:534config.parentField ?? detectParentField(objectSchema, schema.objectName)。⇒objectName已经在手,item 1 不需要改签名,只改tree臂的判断。四个 fixture,逐行取出:

卡自己把可达性说清楚了,我复核同意:外指
tree从已解析的元数据不可达(spec 在 parse 时就拒了),只从手搭 schema 可达。⇒ 今天没有真实作者路径能触发它,损害是「防御纵深上的一个洞」而不是在跑的错误。加上 item 2 纯属 fixture 卫生。⇒ p3。⛔ 不升 p2:升级条件我明确写在这里,供后来者判断——若测得任何非测试代码路径能把未经 spec 解析的 schema 喂给
ObjectTree(例如某个 preview / designer 直接传字面量 schema),可达性就成立,届时按 p2 重定级。本轮未测这一点。pm:queue—— 卡说不依赖 pin,复核同意卡写「Neither item depends on the pin moving, so no
Blocked-by:」。成立:item 1 是 objectui 自身逻辑(spec 侧规则已在main上落地且已发布形态无关),item 2 是四个 fixture 的本地重命名。两者都不需要读GanttConfigSchema那类新 shape。a472b0716)」。实测 objectui 没有 SHA pin 文件——a472b0716在 objectui 整棵树 0 命中,objectui 用 npm semver 钉 spec(^17.0.0/^17.2.0,lockfile 解析到@objectstack/spec@17.2.0)。对本卡无影响(它本就不依赖 pin),但同批的 #7845 依赖它,我已在那边写明。Generated by Claude Code

The card's body is wrong about the fourth (plugin-detail spells it reference_to, not reference) and the two options are NOT equivalent: measured on the installed spec, FieldSchema refuses reference_to by name with unrecognized_keys plus a rename hint, while a nonsense negative control is refused with no hint, so the hint is attached to a refusal and the key is not legal on any field. Renaming would have converted a refused key into an accepted self-annotation the fixture never made. The other three declare no object identity a self-reference could name, and a copied target value going stale is exactly what produced this card. Mechanism assumptions 1 and 2 verified, 3 verified negative (no pin asserted the foreign shape; the two tree fields in ObjectTree.settledSchemaKeying-6481 are genuine self-references and declare parentField anyway), so no ruled flip and nothing to stop on.", "premise_correction": "The card's item-2 body says all four fixtures spell the target `reference`. The fourth spells `reference_to`. This corrects the card's wording, not its verdict, so premise_still_valid stays true. Separately: the renderer now tightens AHEAD of the installed spec. Probed two-directionally on @objectstack/spec@17.2.0, the copy this branch resolves, a foreign-referencing tree still parses ACCEPT, because refuseForeignTreeReference landed on objectstack main after 17.2.0 was cut.

ABLATION, direction predicted before running and matched: restoring `if (def?.type === 'tree') return key;` on the COMMITTED tree turned exactly the two refusal cases red -- `does NOT pick a tree whose reference names another object` and `and no longer MASKS a self-referencing lookup declared after it` -- with Test Files 1 failed | 2 passed (3), Tests 2 failed | 17 passed (19); both live arms, the degenerate-pass guard, both lookup regression controls, both spec-anchored controls and the sibling -6837 and -6481 pins stayed green. Mutation proven ON DISK by anchor counts either side (guarded arm 1 to 0, bare arm 0 to 1) and by a blob-hash change away from the HEAD blob; restored with `git checkout HEAD -- path` under an EXIT/INT/TERM trap using an absolute path, proven by `git diff HEAD` empty AND by the hash returning to the HEAD blob.

hasDetectableParentFieldincluding the own-name guard, and the check moved belowconst ref = …so it can read the target. Precedence is preserved — atreestill returns immediately whilelookuponly setsfirstSelfRef. ✅⭐ A second live defect came with it, and it is the better half. Because the arm now skips instead of early-returning, a foreign
treecan no longer mask a self-referencinglookupdeclared after it — previously it won by position and the forest rendered flat. Pinned as its own case. That defect was in neither the card nor the triage.⭐⭐ The premise correction — this falsifies triage's own priority rationale
Triage set p3 on this reasoning: 「外指
tree从已解析的元数据不可达(spec 在 parse 时就拒了),只从手搭 schema 可达。⇒ 今天没有真实作者路径能触发它」.The dev probed the spec copy this repo actually installs, two-directionally:
business_unit@objectstack/spec@17.2.0{ type: 'tree' }{ type: 'tree', reference: 'business_unit' }{ type: 'tree', reference: 'other_object' }refuseForeignTreeReferencelanded on objectstackmainafter 17.2.0 was cut, and objectui tracks the spec by npm semver, not by SHA (the lane fact triage itself established on this card). ⇒ The shape is reachable from parsed metadata today. The p3 rationale was false on the installed version, not merely narrow — and until the semver range moves,detectParentFieldis the only door.The priority question is moot now that it is fixed, but the reasoning is recorded because the same "the spec refuses it at parse" argument is load-bearing on other open cards, and it is only true of a spec copy that carries the rule.
⭐⭐ The best judgement in this delivery is a test that was deliberately NOT written
The obvious extra control — assert
ObjectSchema.safeParserefuses the foreign shape — is absent, and the pin's docblock says exactly why: on 17.2.0 it would be RED, so writing it would plant a green that does not prove what it claims. Instead the file pins only the half 17.2.0 does answer (referenceis optional on atree, so the accept-when-absent arm is not blessing a rejected shape) and leaves an explicit instruction to add the refusal leg when the pin moves. ⛔ Do not delete that control later.Drop vs rename — measured, not preferred
The card authorised both. The dev dropped in all four, and grounded it: probed two-directionally on the installed spec with a nonsense negative control, the retired snake spelling is refused by
FieldSchemaby name withunrecognized_keysplus a rename hint, while the nonsense key is refused with no hint ⇒ the hint attaches to a refusal, so the key is legal on no field. Renaming would have converted a refused key into an accepted self-annotation the fixture never made. The other three containers declare no object identity a self-reference could name. Accepted.reference— the fourth isreference_to. Triage caught it; the dev confirmed it. Wording corrected, verdict unchanged.Derived work
#8031 filed correctly —

It found three more foreign-shapedtreefixtures that areference:-keyed enumeration misses, by scanning everytype: 'tree'emit instead of grepping one key ⭐ — the same blind spot that nearly cost this card its own fourth fixture.
