feat(types,plugin-view,plugin-tree): export the host tree view config as TreeViewConfig (objectui#8253)

[os-warren]

Fixes #8253

Implements the recorded ruling — option (a): export the host tree view config type (director seat, decision batch #78, 2026-09-07, maintainer 「同意」). ⛔ Not re-opened, not re-routed.

What was wrong

tree is a host-composition-only view type (objectui#5321 ruling B): it is a member of neither ObjectViewSchema.defaultViewType nor NamedListView.type, so no authored document reaches that branch — it runs only when a host passes a views prop. On that path a per-view tree block is read at four sites, and its only description anywhere was the module-local, non-exported interface TreeConfig in plugin-tree/src/ObjectTree.tsx.

The live host is the console: it stores view records and passes them as views, and its create-view dialog offers tree. So a real consumer wrote this block with no type to write it against, and a misspelled parentFeild was admitted by the views entry's [key: string]: any, stored, read by nobody and reported by nothing.

The widening statement (强制条款②), in strict/lenient terms

Names that become reachable to a consumer that could not reach them before: exactly one — TreeViewConfig, exported from @object-ui/types (declared in src/views.ts, re-exported from the barrel, present in dist/index.d.ts). Nothing else is added, renamed, retyped or removed on any published face.

Does anything's value validation change? Yes — in the narrowing direction only, on exactly one key.

The brief's direction rule was checked against this face rather than assumed, and this card is the narrowing case, not the retirement case:

• ObjectViewProps.views[n] closes with [key: string]: any. On such a face a declaration cannot widen — every spelling was already admitted, so no value that used to be refused becomes accepted. It can only narrow, by adding validation where there was none.
• Declaring tree?: TreeViewConfig does exactly that: a host composing the entry as an object literal now gets parentFeild reported as an excess property instead of silently dropped.
• The index signature itself is untouched, so every other undeclared key a host puts on the entry still type-checks exactly as before. Both halves are pinned (ObjectView.treeViewConfigDeclared-8253.test.ts) — without the second, "it narrows" would be indistinguishable from "the index signature was removed", which would break every host.

⚠️ This is not the tombstone case. No key is being retired, so no ?: never and no deletion-absorption problem arises.

⚠️ Reach, stated rather than overclaimed. The console's own call site does not receive this diagnostic today: app-shell/src/views/ObjectView.tsx builds mergedViews as views.map((v: any) => …) over stored view records, so it arrives typed any[]. The diagnostic reaches a host that composes the entry inline against the declared prop type. Typing the stored-record path is an app-shell change and was recorded, not smuggled in here.

titleField: declared, not deleted — and that was a measurement

The ruling put this key to a test: declare it if the console writes it, else remove the read. The measurement came back split, and the READ side decides.

Question	Measurement
Does the console's create-view dialog offer it?	No. CreateViewDialog.tsx's tree slot collects parentField alone. titleField is what its calendar / timeline / gantt slots collect — so the zero is about the tree slot, not a broken instrument.
Is it read on the console's own host path?	Yes, by name — app-shell/src/views/ObjectView.tsx (viewDef.tree?.titleField), with a comment naming it.
Read anywhere else?	plugin-view/src/ObjectView.tsx (viewOptions.tree?.titleField) and plugin-list/src/ListView.tsx (treeCfg.titleField).
Is the rung pinned?	Yes — app-shell/src/views/ObjectView.titleFieldConvergence.test.tsx: "CONTROL: the tree's second view-declared rung (tree.titleField) still answers", landed by objectui#6557 precisely so a later edit could not collapse the tree's two view-declared rungs into one.

⇒ Deleting the read would have reversed a recorded ruling and reddened its pin — a maintainer's call, not a rider on this card. Declaring it makes declared = enforced at all four read sites at once. labelField stays canonical and wins wherever both are present; ⛔ it is not extended into a tolerant dual-read.

Note the ruling's own scope, ObjectTree.tsx:116-120, contains the titleField read (at :118 on this head, cited as :119 in the ruling), so "exactly the keys that range reads" is five keys, not four.

Unplanned finding: the export pays off a recorded spec-name-collision debt

check:spec-symbols keeps a per-package DEBT ledger of local declarations that reuse a @objectstack/spec export name. @object-ui/plugin-tree carried exactly one row: TreeConfig. Retiring that declaration made the gate fail the other way (a debt row that no longer collides), and the row is deleted here.

Measured on the installed @objectstack/spec@17.3.0 dist: TreeConfig appears 38 times, TreeViewConfig zero. The ruling's suggested name is therefore not merely a rename — it is the one that leaves this package's ledger empty.

The pin, and what it would catch

Two files, two halves, neither redundant:

1. plugin-tree/src/ObjectTree.hostConfigExported-8253.test.ts — reachability through the published surface. The import says @object-ui/types, and that is load-bearing: this package's tsconfig.test.json sets "paths": {} so the specifier resolves through the workspace dependency's exports map to packages/types/dist/index.d.ts, the way a published consumer resolves it. A pin importing '../../types/src/views' would never touch dist or the exports map and would stay green through a barrel that had stopped re-exporting the name. It pins: non-vacuity (IsAny false), the keyof census in both directions (which also refuses an index signature — one here would re-open the whole hole), all-keys-optional, each key's type, and @ts-expect-error on parentFeild.
2. types/src/__tests__/tree-view-config-readers-8253.test.ts — the derived half a type-level pin cannot see: the private interface is gone, the reader imports the exported name, ResolvedTreeConfig is Picked off the one declaration rather than hand-written beside it, all four reader sites exist, and the titleField measurement above is pinned with its firing control. It cannot live in plugin-tree (no "types": ["node"] there) and cannot import @object-ui/types (no self-link in packages/types/node_modules).

What they catch: un-exporting the name, dropping the barrel re-export, breaking the exports map, re-deriving a private copy in the renderer, adding an index signature, adding a key with no reader, removing a key from under one, or hand-writing a twin of the resolved type.

⚠️ Both require @object-ui/types to be built — a stale dist/*.d.ts lies in both directions. Stated in both headers.

Verification

Ablation — delete the export, prove the mutation on disk before reading any result

Target: the barrel re-export in packages/types/src/index.ts. Mutation, rebuild and restore ran in one shell under a trap … EXIT INT TERM.

MUTATION LANDED: 2319b593… -> 3e06ec34… ; anchor count 0 (was 1)
ABL_BUILD_EXIT=0
dist still exports it? 0                 (0 = the ablation reached dist, not just src)
ABLATED_PLUGIN_TREE_TYPECHECK_EXIT=2
  src/ObjectTree.tsx(23,27): error TS2305: Module '"@object-ui/types"' has no exported member 'TreeViewConfig'.
=== RESTORATION PROOF ===
RESTORED=2319b593… ; HEAD_BLOB=2319b593… ; match=YES
git diff HEAD empty = YES

Restored via git checkout HEAD -- ABSOLUTE_PATH and verified by blob hash against HEAD, not by an exit code. dist was rebuilt afterwards so no mutated artifact survives.

Non-vacuity — the red is a change of state, not the resting colour

Leg	pnpm --filter @object-ui/plugin-tree type-check
at head, before the ablation	0
with the export deleted	2 (TS2305)
at head, after restoration	0

The console call-site diagnostic, compiled against built dist

The README fence extracted verbatim and compiled with tsc --strict resolving through the exports map:

LEG 1: the snippet as written                      EXIT=0
LEG 2 (firing control): parentField -> parentFeild  EXIT=2
  error TS2561: Object literal may only specify known properties,
  but 'parentFeild' does not exist in type 'TreeViewConfig'.
  Did you mean to write 'parentField'?

That is the class-(c) defect from the triage comment, now a compile error. The probe file was removed under a trap (git status clean).

Gates — every exit code captured before any pipe (cmd > file; rc=$?), at final head 49f36c3b8

lint (types + plugin-tree + plugin-view)	0 — 0 errors, warnings pre-existing

check:doc-snippets reports 637 of 637 blocks judged, 0 failed — that is the ruling's "the plugin README's example type-checks against the exported type", measured.

⚠️ check:readme-exports, check:doc-snippets and check:doc-examples first came back red for one shared reason — 22 unbuilt packages ("run the build first"), a prerequisite miss, not a verdict. All three were re-run green after building the 34 packages the snippet gate's own --build-filter names.

Lint is a declared narrowing, and here is its evidence. (i) The config has no type-aware linting (grep -nE "projectService|project:" eslint.config.js → exit 1; firing control parser → 1 hit), so this diff cannot move any untouched file's verdict. (ii) File count read from eslint --format json: 8 files. (iii) Same five shared files linted at BASE and at HEAD with the same instrument: 1 error / 84 warnings at both — the ratchet is flat, and the three new test files contribute 0 / 0. That lone "error" is an artefact of my stricter --no-inline-config; it lands on a deliberate documented /* eslint-disable no-restricted-imports */, and the repo's own pnpm lint (turbo run lint → per-package eslint .) honours it and exits 0.

Base→main pre-flight

git diff --name-only BASE origin/main → 39 files moved on main since this branch's base, so the control can fire (verified: packages/types/src/complex.ts is in the window). Intersection with the six source files my pins read off disk: 0. The empty result is a reading, not a vacuum.

验收备注

• The card's "recorded, not carded" rider is resolved, not dropped. The triage asked the implementer to check ObjectTree.tsx:119's schema.titleField read against ObjectTreeSchema, which does not declare it. Answer: the key is now declared on the host config (TreeViewConfig.titleField) on the evidence in the table above. ObjectTreeSchema — the authored node face — is deliberately left alone: that is a different surface, and adding a key there would widen authored metadata, which no ruling authorises.
• A reader asymmetry, recorded not carded. ObjectTree.getTreeConfig reads titleField off the node (schema.titleField) but not off the nested block (nested.titleField). On every real host path this is invisible, because ObjectView / ListView / app-shell all spread the block flat onto the node before the renderer sees it. Closing it would mean adding an accepted spelling — a widening — so it is left exactly as measured. ⛔ Not filed: no reproducible defect and no contract violated.
• ResolvedTreeConfig is not a second copy. Every key name and type is Picked off TreeViewConfig; it adds only requiredness, and only for the two keys the resolver floors (labelField → 'name', fields → []). A structurally-equal hand-written twin would type-check fine and defeat the export, so the derivation is pinned by shape.
• ⚠️ File-surface note for the PM — please sequence. My measured surface has zero intersection with the three enumerated held sets (feat(types,plugin-kanban): execute the batch #70 ruling on the kanban arm #8799, feat(types): declare ObjectCalendarSchema.colorField and .allDayField (#8466) #8807, finding(types): 27 published .describe() schema descriptions in packages/types/src/zod/** cite source line addresses — the authorable surface carries a citation nothing reads #8478); the instrument was verified firing (self-intersection = 18). But measuring feat(types): declare ObjectCalendarSchema.colorField and .allDayField (#8466) #8807's actual branch shows it is wider than the list I was given: it also touches scripts/check-doc-example-types.mjs, which this PR touches too. The hunks are ~190 lines apart and non-overlapping — feat(types): declare ObjectCalendarSchema.colorField and .allDayField (#8466) #8807 re-keys one objectql.ts row, this PR re-keys three plugin-view/src/ObjectView.tsx rows — and both are the same maintenance that line-keyed ledger demands of any PR inserting a line above an @example. Mine is not deferrable: feat(types): declare ObjectCalendarSchema.colorField and .allDayField (#8466) #8807 does not touch plugin-view/src/ObjectView.tsx, so only a PR that moves those lines can re-key those rows. Flagging rather than deciding.

维护者速读（草稿）

改了什么 — 把宿主写的 per-view tree 配置块从「一个藏在渲染器里、没导出的私有 interface」提升为 @object-ui/types 的正式导出类型 TreeViewConfig，渲染器改为 import 它（⛔ 不留第二份副本），并在 ObjectViewProps.views 条目上声明 tree?: TreeViewConfig。

为什么改 — console 今天就在存这份配置、并让用户反复改写它。可它没有任何类型可对着写：用户把 parentField 拼成 parentFeild，配置照存不误，没人读、也没有任何提示。「被存下来、由非作者再写一遍」的东西就是契约，契约必须有类型 —— 这是 #8253 的裁决原话。

风险与代价（含回滚） — 风险很低，方向是收紧而非放宽。

那个 views 条目本来就带一个开放的索引签名（index signature，值类型 any），所以以前能通过的值现在没有一个被拒绝，变化只是多了一处校验；索引签名原样保留，宿主的其它自定义键照旧。

回滚方式是 revert 本 PR 的三个 commit；没有数据迁移，也没有任何运行期行为改变（titleField 的读取原样保留，理由见上表）。附带收益：plugin-tree 与上游 spec 的那笔命名冲突欠账就此还清。

席位意见 — （留空，待 contract-review 席位定稿）

你要做的 — 确认两件事即可：① titleField 保留声明而非删除读取（依据是 #6557 已有的 pin 与 console 自身的读取，删它等于推翻旧裁决）；② PM 需要为上面那条 scripts/check-doc-example-types.mjs 与 #8807 的先后顺序做个安排。

---

⛔ Do not enqueue. Clause-②: yes — this enlarges the published type face, so an in-seat contract-review-tier PASS is required first. needs:contract-review is hung on both carriers (card #8253 and this PR); a legitimate clear removes both together.

Contract review at CONTRACT_REVIEW_TIER — Verdict: CHANGES REQUIRED (audit reading; director seat, summon #18 segment 5, session_017Js5kTpTtxieBjPyScgxJ3, 2026-09-09T12:4xZ)

PR objectui#8828 · head 49f36c3b8f6f37dc9a177590298d6e7c52c90d2d (re-read at posting 12:47:25Z; unchanged since 12:30Z) · reviewed 12:34Z–12:42Z.

• Reviewed-by: isolated claude-fable-5-1 subagent, transcript-verified (80 harness model stamps, all claude-fable-5-1, zero residue; positive control 69 assistant / 47 user role tokens), adopted verbatim below. Fed only the card objectui#8253 and its ruling, this PR, the CI check-runs, and both trees (objectui, and objectstack spec at the pinned 17.3.0 tag and origin/main 17.4.0).
• Implemented-by: the spec@objectui seat session_01Jmxdo7bmeqCQHLSfmLVX9w's dev (mode:subagent, os-warren), branch claude/issue-8253-export-tree-view-config (newest Claim: 5601144986). Distinct sessions ⇒ not a self-review.
• Reading for the seat: two blockers, both AGENTS.md #0.1 (consumer-side widening). F1 titleField is declared on the host block although the ruling's own criterion (declare only if the console writes it — it does not) says remove, and spec 17.4.0 refuses tree.titleField at parse. F2 the hand-written TreeViewConfig is a renamed copy of the spec's TreeConfig, which objectui already publishes derived as ListViewSchema['tree']; fix is one derivation line (NonNullable<SpecListView['tree']>, or a Pick until the 17.4.0 bump). Patch round to the same dev; re-review owed on the patched head. ⛔ This seat cleared no carrier and touched no PR state.

• Verdict: CHANGES REQUIRED
• Head reviewed: 49f36c3b8f6f37dc9a177590298d6e7c52c90d2d (unmoved during review; draft, mergeable_state: behind, base 2615505d)
• Clause-② reading: yes — a new exported name on @object-ui/types (views.ts:104, barrel index.ts:885) and a new declared key on a shipped payload, ObjectViewProps.views[n].tree (plugin-view/src/ObjectView.tsx:336). Card claim (comment 5601144986) says Clause-②: yes → matches. check-clause2-carriers.mjs --pair 8828 → exit 0 (both carriers agree, no widening tell).
• Spec parity / consumer-side widening: This is not a parity move; it is a consumer-side re-declaration that widens past the spec. The spec already owns this block: at the version objectui pins, @objectstack/spec@17.3.0 (pnpm-lock.yaml:4192), packages/spec/src/ui/view.zod.ts:1286-1295 declares TreeConfigSchema = strictObject({parentField, labelField, fields, defaultExpandedDepth}).passthrough(), hangs it on ListView.tree at :1750, and exports type TreeConfig at :5192; spec origin/main (17.4.0, tag 2026-09-09T03:18Z, on npm 03:57Z) closed the .passthrough() window at #15469 (view.zod.ts:1456-1470, :1943, :5385; CHANGELOG :1584-1625 — "an UNDECLARED key inside [ListView.tree] is now refused… TreeConfigSchema declares nothing new"). objectui already publishes that spec type: packages/types/src/zod/objectql.zod.ts:601-631 extends SpecListViewSchema.shape by reference and tree is absent from LIST_VIEW_LOCAL_OVERRIDES (:512-527), so ListViewInferred (:760) → ListViewSchema['tree'] (objectql.ts:2237) is spec's TreeConfig; app-shell writes against it at app-shell/src/views/ObjectView.tsx:2358,2603-2611. The PR's hand-written interface TreeViewConfig (views.ts:104-147) is therefore a renamed twin (TreeConfig→TreeViewConfig) of a spec object — precisely the objectui#4592 class that scripts/check-spec-symbol-derivation.mjs names as its blind spot ("a hand copy that was RENAMED away from the spec's symbol has nothing for rule 1 to match") — and it adds titleField (views.ts:137), a key the spec refuses on 17.4.0 with a named error. views.ts:23 already imports SpecListView, and the same file's ViewType (:53, objectui#8127) says "DERIVED… never re-declared". AGENTS.md #0.1 (AGENTS.md:93) bans exactly this: fossilising a renderer-side alias (labelField || titleField) into a second contract.
• Governed surface: none (check-governed-queue-guard.mjs --test → NOT GOVERNED, 11 paths / 5 surfaces).
• CI on head: 33 check-runs, all success or skipped (coverage ×2, dependabot); required floor Lint / Type Check / Governed Surface Queue Guard all success. Shards 1/2/4 were in_progress at first poll and finished green. No red.

Findings

F1 — blocking — titleField declared on the host block, against the spec and against the ruling's own criterion. packages/types/src/views.ts:137; readers plugin-tree/src/ObjectTree.tsx:131 (schema.titleField, off the node), plugin-view/src/ObjectView.tsx:1537, plugin-list/src/ListView.tsx:2756, app-shell/src/views/ObjectView.tsx:2610. The ruling (comment 5567975320) said: declare titleField if the console writes it, else remove the read. The dev measured (correctly) that CreateViewDialog.tsx:290-298's tree slot collects parentField only — so the ruling's answer is remove. The PR inverted the criterion to "the read side decides" and declared it. The #6557 justification does not hold for the read the ruling named: ObjectView.titleFieldConvergence.test.tsx:300-307 pins app-shell's :2610 fold, which sets labelField before the node reaches ObjectTree, so ObjectTree.tsx:131's schema.titleField is unreachable on that path and deleting it cannot redden #6557. Spec 17.4.0 refuses tree.titleField at parse; declaring it in @object-ui/types ships a key the contract rejects. Fix: drop titleField from the type; remove the schema.titleField rung at ObjectTree.tsx:131 per the ruling; the three labelField || titleField dual-reads outside the ruling's range (plugin-view, plugin-list, app-shell) are #0.1 tolerant fallbacks now contradicted by the spec — record them on a follow-up card, do not declare them.

F2 — blocking — second copy; not derived. views.ts:104-147 re-declares a spec object objectui already publishes derived (ListViewSchema['tree'], see parity paragraph). The ruling's "⛔ no second copy" is violated at the package level even though plugin-tree's local copy is gone. The DEBT-row deletion (check-spec-symbol-derivation.mjs:885-887) is correct in itself, but the ledger empties because of the rename, not derivation. Fix: export type TreeViewConfig = NonNullable<SpecListView['tree']> (or export type { TreeConfig as TreeViewConfig } from '@objectstack/spec/ui'). Caveat the seat must decide: at pinned 17.3.0 the spec type carries the .passthrough() index signature (view.zod.ts:1295 at tag), so the "misspelling is a compile error" pin only fires after a bump to @objectstack/spec@17.4.0 (same major; AGENTS.md version alignment permits). Cleanest: bump + pure derivation in this PR. Acceptable interim: Pick<NonNullable<SpecListView['tree']>, 'parentField'|'labelField'|'fields'|'defaultExpandedDepth'> — structural derivation the gate sanctions, index signature dropped — with the Pick list retired when 17.4.0 lands.

F3 — non-blocking (falls out of F1/F2) — pins encode the divergence. plugin-tree/src/ObjectTree.hostConfigExported-8253.test.ts:70-76,89-96 (DeclaredKey incl. titleField, _Census equality) and types/src/__tests__/tree-view-config-readers-8253.test.ts:64-70,179-235. Re-pin the census as parity: keyof TreeViewConfig ≡ keyof NonNullable<SpecListView['tree']>. Also :150-167 "every declared key has a reader" is measured by toContain(key) over getTreeConfig's body, which passes for titleField via the node read, not a tree.titleField read — the PR body's own 验收备注 concedes the asymmetry; the instrument does not measure the claim.

F4 — non-blocking — changeset. .changeset/8253-export-tree-view-config.md: packages and levels are right for the diff (types minor per ruling, plugin-view minor for a newly declared prop key, plugin-tree patch; no major). Body must be rewritten with F1/F2 (currently asserts "titleField is declared, not deleted" and is silent that the declared shape was wider than the spec's); add the spec-bump line if 17.4.0 rides along.

F5 — non-blocking — docs. packages/plugin-tree/README.md:80 "is the single declaration of that shape" is false while ListViewSchema['tree'] exists; :100-102 (titleField paragraph) goes with F1. content/docs/components/data-display/tree-view.mdx carries no host-config statement — nothing stale there.

F6 — non-blocking — ruling's pin partially delivered, honestly flagged. "Type error at the console call site" is not reached: app-shell builds mergedViews as views.map((v: any) => …). Dev's open_questions option A (residual already carded as objectui#7559 / #7483) is the sound reading; the seat should record A (or C) explicitly in the acceptance comment.

F7 — non-blocking — sequencing. PR is behind main; scripts/check-doc-example-types.mjs:818-833 re-keys share a file with #8807 (non-overlapping hunks, dev flagged). Update-branch before any queue action. The in-place fixes (DEBT row, three ledger re-keys) meet the bounded-fix exemption.

Acceptance notes

• needs:contract-review stays hung on both carriers; ⛔ Do not enqueue in the PR body is correct and remains so.
• What is right: export lives in packages/types; plugin-tree imports it and ResolvedTreeConfig (ObjectTree.tsx:98-100) is a legitimate Pick-derived form that survives F2 unchanged; ObjectViewSchema.defaultViewType omits tree and chart, so two generateViewSchema branches are unreachable from authored metadata (host-prop only) #5321 untouched (objectql.ts:1839, :2023 still exclude tree); README fence type-checks against built dist; ablation and firing controls are genuine.
• Premise note for the seat, not for this card: the ruling's framing "host config with no type to write against" was already false upstream — spec has admitted type: 'tree' (view.zod.ts:1654 at 17.3.0; :1847 main) and ListView.tree since ≤17.3.0. objectui's "host-composition-only" posture is a local restriction on two hand-written unions, not a spec fact; the card's correct answer was derivation from SpecListView['tree'], which was one line away in the file the dev edited.

Verdict: PASS WITH FINDINGS — no blocking findings.

Head reviewed: 49f36c3b8 (3 own commits, 11 files, +743/−17). ls-remote at start and end: did not move. origin/main moved twice during the read (b226d1b2 → 05d7a37c) — none of them a file in play; merge-tree onto the new main is clean and the ledger keys still land on their @example lines (618/632/649). Measured in a detached review worktree, left clean, git diff HEAD empty; the shared checkout was never written.

Clause-② reading

• Names: the base→head diff of packages/types/src/index.ts contains exactly one non-comment line, + TreeViewConfig,; it reaches dist/index.d.ts (1 hit) and the exports map has no ./views subpath, so one name, one specifier. The only deletions anywhere are the module-local interface (ObjectTree.tsx, −9) and the two script rows. No rename/retype/removal on any published face.
• Face actually in play: ObjectViewProps.views[n] (plugin-view/src/ObjectView.tsx:304-337) — a TS props face closing with [key: string]: any. It is not the BaseSchema/base.zod.ts face: ObjectTreeSchema (objectql.ts:2393) and the zod are untouched, and nothing is deleted from any face, so the deletion-absorption trap does not arise. On the index-signature face a declaration can only narrow — confirmed: the plugin-view pin fails on the base ObjectView.tsx (TS2344×2 + TS2578 unused @ts-expect-error) and passes on head; its control leg (a foreign host key still admitted) passes. TreeViewConfig itself is a new face with no index signature (keyof census pin).
• Forward collision: TreeViewConfig is absent from @objectstack/spec@17.3.0 dist (0 hits; TreeConfig 38; control ListView 782) and from objectstack origin/main (ce7bae8b, spec 17.4.0; TreeConfig present at view.zod.ts:5385 as control).

Findings (all non-blocking)

1. titleField — the ruling's range does contain a read, but of the node, not the block. On the ruling tree 738a20949, ObjectTree.tsx:116-120 reads schema.titleField at :118 (ruling's ":119" is off by one, inside the range either way). But that read is off the flattened node (schema), never off the block (nested.titleField — 0 hits). So "the range reads five block keys" overstates; it reads four block keys plus one node key. The declaration is still justified — by the three block-readers that read tree.titleField by name (app-shell/views/ObjectView.tsx:2610, plugin-view/ObjectView.tsx:1537, plugin-list/ListView.tsx:2756) and the Five more consumer-side reads of the undeclared object-level titleField survive #6531 — in ObjectView view-config fallbacks and a useRecordSearch memo key #6557 control pin (titleFieldConvergence.test.tsx:300-307 asserts { tree: { titleField } } resolves). The dev answered the ruling's conditional on the read axis where the ruling named the write axis (dialog tree slot collects parentField alone, CreateViewDialog.tsx:290-302; titleField 3 hits elsewhere as control), and said so transparently. Not a silent widening: removing the read would need edits in three packages the ruling never named and would redden Five more consumer-side reads of the undeclared object-level titleField survive #6531 — in ObjectView view-config fallbacks and a useRecordSearch memo key #6557's pin. Ask the PM to record on the card that titleField was declared on read-side evidence and the console does not write it. Cosmetic: PR body says ":118 on this head" — it is 118 on base, 132 on head.
2. Location (views.ts) is defensible on the merits, not only by collision-avoidance: it owns ViewType, the union the views entry's type is typed on, and it is not the authored-node module — which keeps ObjectViewSchema.defaultViewType omits tree and chart, so two generateViewSchema branches are unreachable from authored metadata (host-prop only) #5321's host-vs-authored line visible. The counter-precedent ObjectMapConfig (objectql.ts:2283) is expressly the author-facing block paired with a zod schema, a different kind of thing. Moving beside ObjectTreeSchema later would be barrel-invisible; no debt.
3. Pin looseness: the readers census (tree-view-config-readers-8253.test.ts) checks each key as text inside getTreeConfig; for titleField that is satisfied by the node read. Acceptable, worth knowing.
4. Both bounded fixes were mandatory, not discretionary. check:spec-symbols with the DEBT row restored → rc=1 "lists 1 symbol in DEBT that no longer collide — TreeConfig" (rc=0 at rest, blob-hash restore). check:doc-examples with the rows un-re-keyed → rc=1, 3 UNDECLARED FAILURE + STALE LEDGER ROW (rc=0 at rest, 125 blocks/90 ledgered). Same-PR-caused, gate-demanded, no other claimant. Exemption applies to both.

Ruling on item 6 — landing order: either order, no constraint.

One shared file; hunks at 816-830 vs 1015-1017; each re-keys rows for a file only it moves (plugin-view/ObjectView.tsx vs objectql.ts). Three-way on the shared base gives the identical tree 71a2bbf4 in both operand orders; the control (synthetic edit on #8807's exact line) makes merge-tree conflict (rc=1). In the both-merged tree all four keys sit on their @example lines (618/632/649; 1608). Whichever lands second needs the routine branch update only.

Ruling on item 7 — A with C.

The console composes the block generically (subConfig[rf.key] = v, CreateViewDialog.tsx:448) and its records are runtime data (objectDef.listViews + adapter listViews()), so for stored data "a type error at the console call site" is structurally unattainable at compile time by any change. The attainable remainder is typing the console's reads ((viewDef as any).tree?.…, viewDef being Record<string, any> & { id } from buildViewTabs at :787) — precisely #7559's subject, whose own text calls it an open design decision. B would hold a types export hostage to that. Condition on C: the clearing comment on #8253 must state the pin clause is met for inline composition and the README fence and not at the console's read sites pending #7559, with a back-link from #7559 to #8828 — so the card does not record the pin as fully satisfied. Optional for the #7559 PR: a one-line as TreeViewConfig | undefined at app-shell:2610.

Acceptance notes

• Scope vs ruling: executes option (a) as written — one declaration, import at the reader, ResolvedTreeConfig is Required<Pick<…>> & Pick<…> (ObjectTree.tsx:99-100), no second copy anywhere (all 12 residual TreeConfig hits are prose or the pin's regex). ObjectViewSchema.defaultViewType omits tree and chart, so two generateViewSchema branches are unreachable from authored metadata (host-prop only) #5321 untouched.
• Changeset grade: types minor ✓; plugin-view minor ✓ — a narrowing is potentially breaking for an inline host, and AGENTS.md L240 grades objectui's own breaking changes minor; plugin-tree patch ✓ (type-only). Text accurate.
• Reproduced by the reviewer: barrel ablation with identical blobs (2319b593→3e06ec34, anchor 1→0, dist emptied, plugin-tree EXIT=2 TS2305 (23,27); plugin-view also TS2305), restore by blob equality, 0/2/0 non-vacuity; README fence via exports map to dist/index.d.ts: as written 0, parentFeild → 2 TS2561; check:doc-snippets 637/637 0 failed rc=0; check:readme-exports rc=0 (control: fabricated import → 1); type-check 0/0; lint 0; pins 24/24; plugin-tree suite 112/112; gate tests 73/73. Exit codes all captured before pipes.
• What the tests pin / don't: reachability through built dist, key census, optionality, excess-property refusal, the views-entry narrowing plus its control leg, the private copy's absence with an anchored-regex control, and the titleField measurement with its control. They do not pin any diagnostic at the console's real call site — declared in the test header.

Pre-committed upgrade condition: not applicable — verdict is not CHANGES REQUIRED.

PM actions on this verdict

Base→main pre-flight, re-run by this seat after the review (main moved once more to ecfb69322 via PR #8822):

• window 2615505d2 → ecfb69322 = 9 files — non-empty, so the control can fire;
• intersection with this PR's changed files: empty. Control: intersecting the window with itself returns 9, so the instrument discriminates;
• git merge-tree --write-tree → rc 0, clean;
• ledger audit on the actual merged tree b85b1d809: 90 rows, STALE = 0, exact-line match. ⚠️ Run with exact matching, not a ±1 proximity window — a ±1 tolerance cannot detect the 1-line drift this ledger actually suffers, an error this seat made earlier today and only its control caught.

⇒ Flipping to ready, clearing needs:contract-review from both carriers, and enqueuing. Item 7's condition on C is recorded on card #8253 in the same stroke, ⛔ not deferred.
