Requested by 田騏 · project thread

Full review owed at the reviewer tier. Developed on the default tier while the reviewer tier's quota is out. This PR touches the published spec (packages/spec/src/**), so it lands only after a full review at the reviewer tier and a CONTRACT_REVIEW_TIER contract review record PASS on the current head.

Fixes #28006

Clause-②: no
Metadata-protocol: none

维护者速读

• 改了什么： fix(spec)!: composeStacks refuses a datasource whose external.connector names no connector instance the composed inputs declare #27939 的合成检查里，有一种情形的拒收理由不对：包体里的连接器和产物顶层的同名连接器一个能出借、一个不能。原提示说「运行时每个包各留一条，先注册的出借」。实际上，开机时顶层那条不注册，由包体那条出借；开发态重载时，顶层那条会替换包体那条。现在提示写明这一点；slot 文档和 providedCollectionEntries 的说明也写清了。另外改了一个测试名，并补了 preserve 下混合嵌套输入的测试。
• 为什么改： 结论正确但理由错误，会误导作者判断该改哪一条声明。
• 风险与回滚： 接受集不变：原来拒收的仍拒收，原来通过的仍通过，只改提示文字。两个包体之间冲突的提示一字未改。回滚即 revert。
• 先看： packages/spec/src/stack.zod.ts 中 collectComposedDatasourceConnectorErrors 的歧义分支，以及 ProvidedCollectionEntry.inBody 的文档。
• 两分钟验证： pnpm --filter @objectstack/spec exec vitest run src/stack-datasource-connector.test.ts，预期 30 个测试全过。
• 需要您做的： 无（需审阅档全量复审与合约复审 PASS）。

What changes

• packages/spec/src/stack.zod.ts:
  • ProvidedCollectionEntry gains inBody: whether the entry boots as a package body's own item. That covers an entry of a packages[] body, and, under preserve, the top level of an input that preservePackageEntries folds into a body of its own id. Its doc states the mechanism for every other top-level entry beside package bodies. The residual rule (unclaimedTopLevel) does not register such an entry when a body declares its name. When no body declares the name, the rule registers it under the composed artifact's manifest.id (the last input's). A dev reload replaces the booted entries of the name with the artifact's top-level list (mergeDeclaredConnectorSources). So its slot ('artifact', or a mixed preserve input's own package:${id}) is a stand-in. It stays a stand-in because keeping it apart from the bodies is what refuses the boot-or-reload split as ambiguous.
  • The ambiguity finding now names the mechanism that applies:
    • Two package bodies: unchanged, byte for byte ("the runtime keeps one entry per package and lends from whichever registers first").
    • A package body and a top-level entry: "which the composed artifact declares both in a package body and at its top level, … The boot does not register a top-level entry whose name a package body declares, so the body's entry lends, and a dev reload replaces it with the artifact's top-level entries of the name, the first of which lends, so the entry the datasource borrows depends on whether the artifact was booted or reloaded and on the order of its inputs."
    • Top-level entries of two inputs, beside bodies that do not declare the name: a sentence of its own: no door registers either as a package body's entry, and a dev reload lends from the first top-level entry of the name.
  • providedCollectionEntries' docblock and collectComposedDatasourceConnectorErrors' docblock say the same.
• packages/spec/src/stack-datasource-connector.test.ts:
  • "treats a package body and another input's top level as two slots" is renamed to "refuses as ambiguous a top-level entry beside a package body's same-named entry, and names the body". It now asserts the new sentence and the absence of "one entry per package".
  • A new group pins the preserve reading of an input that carries packages beside its own top-level connectors. With a descriptor at its top level and another package's lending instance, it is refused as ambiguous, with the beside-a-body sentence, in both input orders. With two lending instances it composes in both orders. The composed artifact keeps that top level beside the inner and plain bodies only, under the last input's manifest.id, and the whole flattened connectors list in input order (pinned both ways, since a dev reload lends from the first). Two such inputs whose top-level entries disagree, beside bodies silent on the name, are refused with the top-level-only sentence in both orders.
• .changeset/28006-composed-connector-ambiguity-reason.md: @objectstack/spec patch (the message text ships), both declaration lines, and an ADR-0087 not-required (no-migration-prescription) marker.

Why

Should-fix 1 of contract record 6516406275 on PR #27939: the refusal was right for a reason the message, the slot doc and the test name did not give.

Verification

All on head 541d7f5b3d (should-fixes 1 and 2 of contract record 6519281283 in 1580237, then a merge of origin/main).

• Verdicts unchanged: the 30 tests were run against origin/main's stack.zod.ts. The 25 that do not assert the new wording passed. The 5 that do failed only on that wording: each first asserted the envelope (STACK_CROSS_REFERENCE_INVALID, 422) and exactly one finding for the datasource, and those assertions passed. So every composition this file covers is refused or accepted exactly as before.
• Ablation: with the mixed input's top level judged in the composed artifact's slot instead of its own, both orders of the mixed preserve refusal go red, and the mixed-first order is accepted. The 26 other cases stay green. Restored, 28/28 pass (measured on 55b0c85641, before the two cases should-fix 2 added).
• Package: pnpm --filter @objectstack/spec build, test and typecheck under the verify lock: build exit 0; 756 test files passed, 22505 tests passed (1 todo); typecheck passed (check:test-typecheck: OK).
• Local gates: node scripts/pm/dispatch-gates.mjs --commands, derived after merging origin/main, named 80 families (re-derived after the second merge of origin/main). All were run, with exit codes recorded before any pipe, and every one exited 0. dispatch-gates --ran: "80 derived famil(ies) accounted for — 80 run, 0 NOT-MEASURED (a DERIVED zero)". The tree was clean after the gate run, so no generated reference moved. The full gate battery is CI's. Dogfood was not run: Clause-②: no does not owe it, and no verdict moves.

Acceptance notes

• The slot stays a stand-in on purpose. Judging a mixed input's top level in the composed artifact's manifest.id slot, where the residual rule registers it, would move a verdict: with the plain input last, a descriptor at the mixed input's top level would be judged last-wins against the plain body's instance and accepted. The card forbids that, so the doc states the mechanism instead.
• Worktree: objectstack-issue-28006 on the claimed branch, as the Claim names.

Human Minimum

• 1. Schemas start as Zod; packages/spec holds no runtime logic. (Message wording of a build-time collector and one module-private field; no schema changed.)
• 2. Every name I added uses the casing for its kind.
• 3. No formatter ran; pnpm lint is CI's.
• 4. One issue, one branch off an up-to-date main, one pull request.
• 5. A change that publishes carries a changeset, and both declaration lines are filled in here and in the changeset.
• 6. packages/spec touched: no generated artifact changes (only JSDoc and a refusal's text; the gate run left the tree clean).
• 7. No hand edits to content/docs/references/, packages/*/CHANGELOG.md or content/docs/releases/.
• 8. Title, body and comments are in English (the 维护者速读 block is the repo's own Chinese reader section).
• The Before Submitting list in CONTRIBUTING.md is done.

📓 Docs Drift Check

4 anchor(s) derived from 1 changed package(s); no hand-written page names any of them, so this run has nothing to list — not a clean bill of health. This check sees only pages that NAME a derived anchor: one that documents this change in prose, or enumerates it in an authoring dialect, names none and stays invisible to it on every run.

What this run could not see

• the SDK route bridge reached 58 of 210 client-bound route-ledger rows — the other 152 have no registrar path: tail to select them, so pages documenting THEIR client methods cannot appear above, on this or any run. Of those 152: 0 are remediable by widening that discovery convention (an in-repo file declares the path; the convention did not scan it); 55 are structural — on a ledger where NOT ONE row is declared in-repo, so no discovery change reaches them at any price; 97 are undecided (no in-repo declaration, on a ledger that has other in-repo registrars — absence and an unreadable spelling are not distinguishable here). The rows themselves: node scripts/docs-audit/affected-docs.mjs --bridge-coverage
• a page that states a rule by its inputs shares no identifier with the emitter that implements the rule, so an emitter-only diff cannot list it — not on this run and not on any run. Measured on fix(driver-sql): emit varchar(maxLength) for a text field a declared index keys on #11430: content/docs/protocol/objectql/types.mdx documents the text-family column mapping by the ObjectQL type names it maps FROM (text / textarea / html) while the diff changed createColumn; it went unlisted, and it was the page that diff falsified, in four places. No shared token exists to detect this on, so a rule your change carries has to be re-read by hand in the pages that restate it.
• a key NAME is not a key, so the hand re-read the line above prescribes can land on the wrong schema. The same spelling is authorable on one governed type and a [REMOVED] tombstone on another for each of active, aria, joins, objects, template, tools and version (censused on [finding] tools is a key on BOTH AgentSchema (tombstoned, dead) and SkillSchema (live, cloud-attested), so a name-based search attributes skill examples to the agent key — it produced a false stop-the-line alarm on PR #19059 #19093 over the liveness ledger's governed types, top-level keys); nothing in a search result distinguishes the two, so a grep hit on a LIVE example reads as evidence about the DEAD key. Measured on fix(spec): the agent.tools liveness row says dead — it claimed live on a key the schema tombstoned #19059: content/docs/ai/agents.mdx was reported as contradicting the agent.tools tombstone over its tools: example at :161, which is inside the defineSkill({ block opened at :155 — the page was already correct. Settle ownership by PARSING the value against both schemas, never by the name: that literal PASSES SkillSchema, and as an AgentSchema it FAILS at tools with the tombstone prescription. ⛔ These names are not the whole class — a key retired through a .strict() guidance map leaves no tombstone in the walked shape and none of them here (tool.category, live as AIToolDefinition.category).

Coarse fallback — 168 page(s) merely mention a changed package (the pre-#9192 predicate, kept for the deliberately-wide backstop): node scripts/docs-audit/affected-docs.mjs --json e1dde1a5c15566bcc24d6c641b53d8282fcf655b → packageMentionDocs.

Which tree this was computed on

This run read content/docs from d7ab1fa78f101a13ca819268dbc2f55aa6eef513 — the merge of head 541d7f5b3dec8648875f63347de6319b39c767eb into base e1dde1a5c15566bcc24d6c641b53d8282fcf655b, which is what actions/checkout gives a pull_request run. Not the PR head.

A worktree cut from an older main holds a different content/docs, so re-deriving there can legitimately return a different list — that is a different tree, not a wrong row. To answer on the same tree:

# while this PR is open — GitHub drops the merge commit once it closes
git fetch origin d7ab1fa78f101a13ca819268dbc2f55aa6eef513 && git checkout d7ab1fa78f101a13ca819268dbc2f55aa6eef513
# afterwards, rebuild it from the two parents, which stay fetchable
git fetch origin e1dde1a5c15566bcc24d6c641b53d8282fcf655b 541d7f5b3dec8648875f63347de6319b39c767eb && git checkout -B drift-repro e1dde1a5c15566bcc24d6c641b53d8282fcf655b && git merge --no-ff 541d7f5b3dec8648875f63347de6319b39c767eb

node scripts/docs-audit/affected-docs.mjs --json e1dde1a5c15566bcc24d6c641b53d8282fcf655b

⚠️ That checkout carried uncommitted changes, so the commit above does not fully identify what was read.

Contract-review-handoff: triage — CONTRACT_REVIEW_TIER unavailable (HTTP 429 rate_limit, 2026-10-30T08:50Z) · head 55b0c85

The seat's at-tier review call is refused by the model quota (last probe 2026-10-30T07:46Z: HTTP 429 rate_limit), and per contract-review.md the tier is not lowered. One same-shape CONTRACT_REVIEW_TIER record, with ④, is owed on this head. Under the 2026-10-29T19:39Z order it also serves as the full review of the spec change.

• Face: published packages/spec/src/stack.zod.ts (Clause-②: no). This is should-fix 1 of record 6516406275 (fix(spec)!: composeStacks refuses a datasource whose external.connector names no connector instance the composed inputs declare #27939). The ambiguity sentence now picks its reason by where the kept entries sit:
  • two package bodies: the old sentence, unchanged;
  • a body beside a top-level entry: the boot drops the top-level twin, and a reload replaces the body's entry with it;
  • top-level entries only: a sentence of its own.
    The slot doc and docblock state the mechanism, a test is renamed to assert the refusal, and a preserve mixed-nested-input test is added.
• Please judge that neither verdict direction moved. The dev ran all 28 tests against main's stack.zod.ts: 25 passed, and the other 3 failed only on wording, with the envelope and one-finding assertions holding. Please also judge that each new sentence matches unclaimedTopLevel and mergeDeclaredConnectorSources.
• Dev's unverified out-of-scope note, not filed: a residual top-level connector may register only into the metadata service and not into the ObjectQL registry the lender reads at boot. If you read that code, please say whether it holds.
• Card composeStacks connector check: say why a top-level connector beside package bodies is refused as ambiguous, and pin the preserve reading of a mixed nested input #28006, claim 6517611093.

Contract review

Served-tier: CONTRACT_REVIEW_TIER
Head-sha: 55b0c85641f709505e5986aac13ee3aa553deb45
Local-runs: none
Scope: packages/spec/src/stack.zod.ts + packages/spec/src/stack-datasource-connector.test.ts, .changeset/28006-composed-connector-ambiguity-reason.md, packages/metadata/src/plugin.ts, packages/metadata/src/metadata-manager.ts, packages/runtime/src/app-plugin.ts, packages/objectql/src/plugin.ts, packages/objectql/src/engine.ts, packages/objectql/src/registry.ts, packages/services/service-automation/src/plugin.ts, packages/services/service-automation/src/connector-credential-source.ts, packages/metadata-protocol/src/protocol.ts

Full review at CONTRACT_REVIEW_TIER on the schema face (one hits path, Clause-②: no), under claim 6519034313 on this head, taken from the triage handoff 6518843869; under the 2026-10-29T19:39Z order it also serves as the full review of the spec change. Inputs: card #28006 (body and its two comments: claim 6517611093 and the os-dev-report 6518764127), PR #28026 (body; 3-file list; net diff against main from the files endpoint; its three comments: the docs-drift advisory, the handoff and the claim), and the check-runs on the head, read twice: at 09:03Z 52 runs with Type Check UI, Test Core (5/8) and Type Check · workspace in_progress, read as pending, not green; at 09:07Z 54 runs, all complete, 40 success, 14 skipped, zero failures, nothing pending. Every required context that ran is success (Lint & Repo Gates, TypeScript Type Check, Test Core and all eight shards, Build Core, Governed Surface Queue Guard, Type Check UI, Test UI, Build & E2E UI, Live E2E UI); Lint UI is path-filtered skipped; Check Changeset, PR-body guards, Spec property liveness, Dogfood Regression Gate, Flag docs affected by code changes and every Lint · and Type Check · lane are success. Nothing was built, run or re-run; the head's files were read with git show at the head, and the cited runtime code at origin/main (main commit 3f02da1; the local checkout's own HEAD is older, so every cited runtime file that differed from origin/main was read from origin/main directly). Record 6516406275 on PR #27939 was read as the ruling this PR implements (its should-fix 1).

① Derived judgments

1. Public surface: none moves. ProvidedCollectionEntry (stack.zod.ts :4512-4545) is a module-private interface and gains inBody: boolean; the inner collect closure of providedCollectionEntries (:4577) takes a fourth argument; providedCollectionEntries (:4567) and collectComposedDatasourceConnectorErrors (:4641) keep their signatures; no export, no .describe(), no authorable key, no generated artifact. packages/spec/api-surface/* untouched; check:api-surface rides the green Lint & Repo Gates. RIGHT.
2. Accept set of composeStacks: UNCHANGED, read off the code rather than the PR's account. The slot of every entry is computed by the same expression as on main (package:${id} / input:${index} for a body's entry; preserve && ownId ? package:${ownId} : 'artifact' for the top level, :4594-4595 against main's :4564-4565); the grouping by name then slot (:4652), the kept entry per slot (:4663), the ambiguity condition (a kept entry that lends beside one that cannot, :4666), the shadow arm (:4692-4705) and the datasource withholding (:4707-4714) are byte-for-byte main's. inBody is read only inside the ambiguity arm, to choose the where sentence (:4671-4687). So every composition refused on main is refused under the same envelope, and every one accepted is accepted. RIGHT; Clause-②: no is the right declaration (② below).
3. Message text: the one published behaviour that moves. Two package bodies: the sentence is byte-identical to main's (the disagree fragment plus "The runtime keeps one entry per package and lends from whichever registers first, so the datasource could boot with no credential.", then the common remedy). A body beside a top-level entry: a new sentence. Top-level entries only, beside bodies: a new sentence. The remedy sentence is unchanged. RIGHT as a declaration; the sentences are judged in ④.
4. inBody derivation (:4588-4595): true for every packages[] body entry; for the top level, true only when the slot is a package: slot AND the input carries no packages array, which is exactly the shape preservePackageEntries (:7069-7080) folds into a body of its own id (an input with manifest and no packages array). An input that carries packages passes its bodies through and its own top level is assembled into no body, so false is right there; a last composition's top level is never folded, so 'artifact' with false is right. RIGHT (one pathological edge in ④, judged, not a finding).
5. Docblocks: slot (:4516-4524) now says the slot is where the entry is JUDGED, and the boot slot only for a body's entry; inBody (:4525-4545) states the residual rule and the reload rule by name and module; providedCollectionEntries (:4549-4566) and collectComposedDatasourceConnectorErrors (:4621-4639) say the same. Each claim is checked against the runtime in ④. RIGHT, with one precision reservation (④ should-fix 1).
6. The test file (no published surface; imports composeStacks and defineStack from the module under test): 28 cases (8 per-stack, 20 composed); one case renamed and re-asserted, one describe of three cases added, header extended. Read to judge the fixtures and what the PR pins; lane seat's ACCEPT.
7. No generated reference moves; no docs page restates the refusal's wording (content/docs, skills/, apps/docs at origin/main carry neither "lends from whichever registers first" nor the new sentence; the one "one entry per package" hit, content/docs/getting-started/examples.mdx :414, is about the packages[] list, not this finding). Docs-drift advisory 6518768418: nothing to list, no hand-written page names a derived anchor. RIGHT.

② Semver level

• .changeset/28006-composed-connector-ambiguity-reason.md: '@objectstack/spec': patch; line-initial Clause-②: no (message text only: ...) and Metadata-protocol: none, both matching the PR body's Clause-②: no and Metadata-protocol: none; one ADR-0087 marker, not-required (no-migration-prescription), a category scripts/check-adr-0087-registration.mjs :557 lists, with its reason. The only published package the diff moves is @objectstack/spec; the move is a refusal's wording, so none takes patch (AGENTS.md Post-Task Checklist 3). Check Changeset success (twice), Lint & Repo Gates success. CONSISTENT in level and kind.
• Clause-②: no is right by ① item 2: no slot, grouping, kept-entry or condition changed, so the accept set is the same set in both directions, and the card's fourth task (no verdict moves) holds on the code. No arm is declared, rightly.
• Metadata-protocol none is right: no key, accepted value, default or meaning of anything an author writes moves.
• The changeset prose, re-read against the tree: "Where it applies" names the two shapes the collector reaches the middle sentence through (a last composition with a nested multi-package input beside another input's top level; a preserve composition with an input carrying packages beside its own collections) — both hold (④). "Top-level entries only" and "Unchanged" hold. Its mechanism sentence ("a dev reload replaces it with the top-level one") carries the same imprecision as the message (④ should-fix 1); prose face, named here for the lane seat.

③ Boundary flags

1. PR body flag ("Full review owed at the reviewer tier ... lands only after a full review at the reviewer tier and a CONTRACT_REVIEW_TIER contract review record PASS on the current head"): answered by this record, which under the 2026-10-29T19:39Z order is both.
2. open_questions: [] on the os-dev-report: nothing to answer.
3. out_of_scope_findings 1 (a residual top-level connector may register only into the metadata service while the lender reads the ObjectQL registry): HOLDS by reading, unmeasured. A top-level item a stack with packages[] carries that no body claims is registered by MetadataPlugin.registerUnclaimedTopLevel (metadata/plugin.ts :1475-1497) through the door's sink: on the artifact door memLoader.save + this.manager.register (:1385-1391), on the config door metadata.registerInMemory (runtime/app-plugin.ts :1127-1148; metadata-manager.ts :887) — the metadata service's registry in both cases. The ObjectQL manifest service registers the bodies through ql.registerApp and, of the residual, its OBJECTS only (unclaimedTopLevelObjects, objectql/plugin.ts :143-153, :773, :836, :848). The lender reads readDeclaredConnectorItems(ctx, { post: true }) (service-automation/plugin.ts :1104-1109), which is protocol.getMetaItemsForExecution({ type: 'connector' }) (:1938-1972), and that read is this.engine.registry.listItems(type) plus the stored sys_metadata overlay (metadata-protocol/protocol.ts :9469-9500) — never the metadata service's list. So a connector a nested or mixed input declares only at its top level beside package bodies, unclaimed by any body, is not visible to a borrow at boot; it becomes visible only after a dev reload captures the payload's top-level list (captureReloadedConnectors :1890-1905). The composed check accepts such a borrow today (e.g. [mixed(instance), looseBorrower] under preserve: the only declaration is the mixed input's top-level instance in slot package:com.acme.bundle, kept, lending, accepted). Outside this PR's file surface and forbidden to it by the card (no accept-set move); escalate: one card, domain:spec / area:data, on the epic PM, naming the boot path above as the measurement to run first.
4. Card composeStacks connector check: say why a top-level connector beside package bodies is refused as ambiguous, and pin the preserve reading of a mixed nested input #28006 tasks against the tree: (1) done both ways the card allowed — the ambiguity sentence is worded for the beside-body case AND the mechanism is stated in inBody's doc and providedCollectionEntries' docblock; (2) the test is renamed to "refuses as ambiguous a top-level entry beside a package body's same-named entry, and names the body" and asserts the refusal, the new fragment and the absence of "one entry per package" (test :288-303); (3) the preserve reading of a mixed nested input is pinned in both orders with a CONTROL that asserts the composed manifest.id, the package list and the kept top level (test :323-368) — with the precision reservation in ④; (4) no verdict moves (① item 2).
5. Handoff 6518843869's three asks: neither verdict direction moved (① item 2, read off the code, not off the dev's run against main); each new sentence matches unclaimedTopLevel and mergeDeclaredConnectorSources in its boot half everywhere and in its reload half under last — the preserve mixed shape overstates the reload half in one order (④ should-fix 1); the dev's unverified note holds by reading (item 3 above).
6. Author objectstack-fleet[bot] through the relay (attribution to marchtian); head repo equals base repo; draft, needs:contract-review carried; branch claude/project-thread-683cod as claim 6517611093 names; the three files are inside the claim's file surface. No governed-register path in the diff.
7. The PR body names no model (it says "the reviewer tier" and "the default tier"); its test counts (28, 20 composed) match the tree. The card report 6518764127 names this head.
8. Local checkout note (reviewer-side, no flag on the PR): the clone's HEAD is behind origin/main, and four cited runtime files differ between the two; they were read at origin/main, where connector-credential-source.ts exists (:83 findDeclared, :99 lendRefusal) and the credential source is wired (service-automation/plugin.ts :1104).

④ Design judgment

packages/spec/src/stack.zod.ts (hits; the schema face) — judged against the ruling it implements (record 6516406275 should-fix 1, as card #28006 states it), its first consumer (composeBuiltStacks step 3b :7757 with preserve threaded), the artifact shapes the tree produces (preservePackageEntries :7069-7080, packagesCarryEveryInputCollection :7131-7146, step 8 :7844-7848, selectManifest :7013, 'last'), and the runtime that registers and lends, all at origin/main: unclaimedTopLevel / claimedArtifactSlots / artifactItemSlot (metadata/plugin.ts :405-426, :335-362, :314-325; connectors in ARTIFACT_FIELD_TO_TYPE :200), registerUnclaimedTopLevel and the two sinks (:1475-1497, :1385-1391; app-plugin.ts :1127-1148), manifest.register (objectql/plugin.ts :773-848), registerApp → registerMetadataCollections → registerItem('connector', stampPackage(item, ownerId, version), 'name', ownerId) (engine.ts; METADATA_ARRAY_KEYS holds connectors), the registry's storage key ${packageId}:${baseName} and overwrite-on-repeat (registry.ts :5576-5580) and listItems in Map insertion order (:6194-6214), captureReloadedConnectors / mergeDeclaredConnectorSources / readDeclaredConnectorItems (service-automation/plugin.ts :1890-1905, :539-557, :1938-1972, hooked at :1664), the lender's findDeclared (first item of the declared list whose name matches, connector-credential-source.ts :83-89) and borrow (:220-222), and the protocol's execution read (protocol.ts :9469-9500).

• The beside-body sentence, boot half, tried on the card's shape (last, [nested(strictPair), owner(descriptor)], test :288-303). The artifact carries the nested input's two bodies (step 3 concatenates packages; the nested input's own top level was stripped by its inner preserve composition) and the plain input's connectors: [descriptor]. At boot resolveArtifactPackageOrder returns the bodies; claimedArtifactSlots claims ('connector', 'sap_s4') from the orders body; unclaimedTopLevel skips the top-level descriptor (:414-416), so no door registers it, and registerApp has put the body's instance in the ObjectQL registry under com.acme.orders:sap_s4. The lender's read lists that one entry; findDeclared answers it; it lends. "The boot does not register a top-level entry whose name a package body declares, so the body's entry lends" HOLDS, through both doors (the config door's manifest service registers bodies and residual objects only, and its residual sink is the metadata service).
• The beside-body sentence, reload half, on the same shape. metadata:reloaded carries the reloaded artifact; captureReloadedConnectors takes its top-level metadata.connectors ([descriptor]) and owners = the artifact's manifest.id; mergeDeclaredConnectorSources drops every registry item named sap_s4 and appends the list; findDeclared answers the descriptor; lendRefusal refuses it. "a dev reload replaces it with the top-level one, so the datasource could boot or reload with no credential" HOLDS under last: there the top level holds the plain input's entries only. The collector's verdict is right in both lendability directions and the reason now names the mechanism that makes it unknowable. The card's named case is discharged.
• The same sentence on the preserve mixed shape (test :342-353), both orders. The collector: the mixed input's top-level descriptor sits in package:com.acme.bundle with inBody: false (it carries packages), the plain input's instance in package:com.acme.orders with inBody: true; one of two kept entries is in a body, so the middle sentence renders in both orders — the test pins exactly that. The artifact: preservePackageEntries yields [orders body, inner body] (or the reverse), and step 8 deletes NOTHING, because packagesCarryEveryInputCollection returns false for an input that carries packages beside its own collections (:7141); so the artifact keeps the WHOLE flattened connectors list, the plain input's instance included, in input order. Boot: both top-level entries are named sap_s4, the orders body claims it, neither registers, the body's instance lends — the boot half HOLDS in both orders. Reload: the appended list is [descriptor, instance] with the mixed input first (the descriptor is found first, no credential: HOLDS) but [instance, descriptor] with the mixed input last, where findDeclared answers the copy of the body's own instance and the borrow is granted. In that order the sentence's "replaces it with the top-level one" names an entry the lender never reaches, and "could ... reload with no credential" does not happen; the refusal there stands on the stand-in slot (the same refusal main renders, for a reason that was wrong everywhere), so the direction is the safe one and no verdict moves. But the PR's one purpose is a reason that is true where it is rendered, and the mixed-last order is a case this PR itself added and pins with the BOOT_OR_RELOAD constant. Should-fix 1: make the reload half true for a top level that holds more than one entry of the name — in the message (:4679-4681), inBody's doc (:4535-4536 already says "the artifact's top-level list", so it is the message, the collectComposedDatasourceConnectorErrors docblock :4632-4635, the changeset and the test's BOOT_OR_RELOAD that say "the top-level one") — e.g. "a dev reload replaces it with the artifact's top-level entries of the name, the first of which lends", and in the mixed-last CONTROL (test :355-367) assert the artifact's connectors order, so the shape the sentence is rendered for is pinned.
• The two-bodies sentence (byte-identical to main's) on the preserve pair (test :232-244): two bodies register under com.acme.orders:sap_s4 and com.acme.sap:sap_s4, listItems lists both in registration order, findDeclared answers the first. "keeps one entry per package and lends from whichever registers first" stands as judged in record 6516406275 ① item 5. No finding.
• The third sentence (top-level entries of two inputs beside bodies that do not declare the name). Reachable only under preserve, with two inputs that each carry packages beside a same-named top-level entry (two package: slots, both inBody: false), or one such input beside a manifest-less input ('artifact'); under last every non-body entry shares 'artifact', so the sentence is never rendered there. Runtime for the reachable shape: both entries are residual; registerUnclaimedTopLevel registers them in order under the composed manifest.id into the metadata service (last wins by name there), where the lender does not read (③ item 3), so at boot neither lends; after a reload the first of the top-level list lends. "The runtime registers neither as a package body's own entry, so the build cannot tell which one lends, and the datasource could boot with no credential" HOLDS. No test pins this sentence, and the boot-or-reload mechanism it rests on is stated less sharply than the other two. Should-fix 2: add one preserve case with two mixed inputs (a descriptor at one top level, an instance at the other, bodies silent on the name) asserting the third sentence in both orders, and let the sentence say what it says for the other two arms: no door registers either as a body's entry; a reload lends from the first top-level entry of the name.
• inBody's doc, claim by claim: "an entry of a packages[] body" (every body entry, :4590-4591) HOLDS; "under preserve, the top level of an input that preservePackageEntries folds into a body of its own manifest id" HOLDS (:7077, an input with manifest and no packages array); "not registered at all when a body declares its name" HOLDS (claimedArtifactSlots compares on the name alone, every body); "registered under the composed artifact's manifest.id (the last input's) when none does" HOLDS (unclaimedTopLevel.ownerId = stack.manifest.id; selectManifest 'last' picks the last input that has a manifest); "a dev reload then replaces the booted entries of the name with the artifact's top-level list" HOLDS and is the precise form should-fix 1 asks the message to take; "'artifact' under last and for an input with no manifest id, and under preserve the input's own package:${id} for an input that carries packages" HOLDS (:4594-4595); "Keeping such a top level in a slot apart from the bodies is what refuses a disagreement with a body's entry as ambiguous" HOLDS, and the PR's acceptance note is right that judging the mixed top level in the composed manifest.id slot would ACCEPT [mixed(descriptor), strictPair] (same slot as the orders body, last wins, the instance kept) although that artifact's reload lends the descriptor — so the stand-in is load-bearing, not a convenience.
• providedCollectionEntries' docblock: "a package body registers under its own id, and so does the top level of an input that preserve folds into a package body" HOLDS; "When no input carries package bodies, 'artifact' is the composed artifact's one package" HOLDS (no packages[], the artifact IS its one package, D7); "Beside package bodies both are stand-ins, because such an entry boots through the residual rule and a dev reload replaces it" HOLDS.
• collectComposedDatasourceConnectorErrors' docblock: the three bullets match the three arms; the two-bodies bullet and the top-level-only bullet hold; the middle bullet carries should-fix 1's wording.
• Judged, not a finding: an input with a manifest that has neither id nor name (reachable through strict: false only; ManifestSchema.id is z.string()) is folded into an id-less body by preservePackageEntries while the collector gives its top level 'artifact' and inBody: false; the slot is main's and the body registers under no id at boot, so nothing here is this PR's to decide.
• Judged, not a finding: packages: [] on a preserve input with an id yields inBody: false and slot package:${id}; preservePackageEntries contributes no body for it, so its top level is residual — consistent with the doc.
• Judged, not a finding: the top-level dedupe by object identity (bodies first, seen) is main's and keeps the both-halves nested shape at one finding (test :305-320).
• The test group: the renamed case asserts the envelope, one finding, both site labels in the new fragment, the boot-or-reload sentence and the absence of the old phrase; the mixed group asserts both orders, the CONTROL asserts the composed manifest.id, the package list ['com.acme.inner', 'com.acme.orders'] (which pins that the mixed input's top level is assembled into no body) and the kept top level. What it lacks: the order of the kept top level in the mixed-last case (should-fix 1) and the third sentence (should-fix 2). Not run here; Test Core 1/8-8/8 success on the head.

Findings. No must-fix. Should-fix 1: the beside-body sentence's reload half ("replaces it with the top-level one, so the datasource could boot or reload with no credential") overstates under preserve with the mixed input last, where the artifact keeps the whole flattened connectors list and the lender answers the body's own copy first; say "the artifact's top-level entries of the name, the first of which lends" in the message, the collector docblock, the changeset and the test constant, and pin the artifact's connectors order in the mixed-last CONTROL. Should-fix 2: the third sentence is unpinned; add the two-mixed-inputs preserve case in both orders and state its boot-or-reload mechanism as the other two arms do. Escalation (③ item 3): the dev's out-of-scope note holds by reading; one card for the residual connector the lender cannot see at boot.

Contract-review-delta-request: head 541d7f5b3d · same reviewer, CONTRACT_REVIEW_TIER

Record 6519281283 (PASS on 55b0c85641) left two should-fixes. The epic PM routed both onto this PR; they are in 1580237, followed by the merge 541d7f5b3d of origin/main (no conflict, the PR's three files untouched by main).

• Should-fix 1: the beside-body sentence's reload half now reads "a dev reload replaces it with the artifact's top-level entries of the name, the first of which lends, so the entry the datasource borrows depends on whether the artifact was booted or reloaded and on the order of its inputs". The same wording is in the message, the collectComposedDatasourceConnectorErrors docblock, the changeset and the test's BOOT_OR_RELOAD. The mixed-input CONTROL pins the artifact's connectors order in both orders (['sap_token_2', 'sap_token'] mixed first, ['sap_token', 'sap_token_2'] mixed last).
• Should-fix 2: the top-level-only sentence now says "No door registers either as a package body's entry, and a dev reload lends from the first top-level entry of the name, so the build cannot tell which one lends, and the datasource could boot with no credential". It is pinned by a new preserve case: two mixed inputs (com.acme.bundle with a descriptor, com.acme.kit with an instance; bodies com.acme.inner and com.acme.toolkit silent on the name) plus a strict: false borrower, in both orders.
• Verdicts: 30 tests. Against origin/main's stack.zod.ts, 25 pass and the 5 wording cases fail only at their fragment assertion, after the envelope, status and one-finding checks. No slot, grouping or condition changed.
• Run on 541d7f5b3d: spec build exit 0; pnpm --filter @objectstack/spec test 756 files / 22505 tests passed (1 todo); typecheck passed. dispatch-gates re-derived after the merge: 80 derived, 80 run, all exit 0, 0 NOT-MEASURED.
• PR body: its counts and quoted sentences name the previous head; the replacement is ready for the seat (the dev does not patch the body).

Contract review

Served-tier: CONTRACT_REVIEW_TIER
Head-sha: 541d7f5b3dec8648875f63347de6319b39c767eb
Local-runs: none
Scope: packages/spec/src/stack.zod.ts + packages/spec/src/stack-datasource-connector.test.ts, .changeset/28006-composed-connector-ambiguity-reason.md, packages/metadata/src/plugin.ts, packages/metadata/src/metadata-manager.ts, packages/runtime/src/app-plugin.ts, packages/objectql/src/plugin.ts, packages/objectql/src/engine.ts, packages/objectql/src/registry.ts, packages/services/service-automation/src/plugin.ts, packages/services/service-automation/src/connector-credential-source.ts, packages/metadata-protocol/src/protocol.ts

Delta review at CONTRACT_REVIEW_TIER on the schema face (one hits path, Clause-②: no), under claim 6520583977 on this head, taken from the delta request 6520193154; the same reviewer session as record 6519281283 (PASS on 55b0c85641f709505e5986aac13ee3aa553deb45), which this record builds on and names where a section stands unchanged. Under the 2026-10-29T19:39Z order it also serves as the full review of the spec change. Inputs: card #28006 (body and its two comments: claim 6517611093 and the os-dev-report 6518764127), PR #28026 (body as it now reads; 3-file list; net diff against main from the files endpoint; its six comments: the docs-drift advisory, the handoff, the first claim, record 6519281283, the delta request and the second claim), and the check-runs on this head, read once at 10:33Z: 53 runs, every one completed, 41 success, 12 skipped, zero failures, nothing in_progress. Every required context that ran is success (Lint & Repo Gates, TypeScript Type Check, Test Core and all eight shards, Build Core, Governed Surface Queue Guard, Type Check UI, Test UI, Build & E2E UI, Live E2E UI); Lint UI is path-filtered skipped as on the previous head; Check Changeset (twice), PR-body guards (twice), Spec property liveness, Dogfood Regression Gate, Flag docs affected by code changes and every Lint · and Type Check · lane are success. Nothing was built, run or re-run.

What moved since the previous head, read locally (both commits present): two commits. The PR's own commit 1580237 ("say which top-level entry a dev reload lends, and pin the top-level-only sentence": 3 files, +53/-21, all three inside the claim's file surface), then the merge commit that is this head, bringing origin/main b00e3f4 in (15 main commits, 74 files, none of them one of the PR's three files: the diff from 1580237 to this head restricted to those three paths is empty). The merge carry-over is main's, not the PR's; of the cited runtime files, none moved between the main commit the previous record read them at (3f02da1) and this head, so every runtime reading in record 6519281283 ④ is a reading of the byte-identical code here. Between this head and the current origin/main (5aee206) one cited file moved, packages/services/service-automation/src/plugin.ts (the connector-mutation reconcile, hunks at :842-848 and :3642-3720): it adds a reconcile trigger and touches neither mergeDeclaredConnectorSources, captureReloadedConnectors, readDeclaredConnectorItems nor the lender wiring at :1104-1109, so nothing below changes against the live tree.

① Derived judgments

1. Public surface: none moves, as in record 6519281283 ① item 1. The delta touches stack.zod.ts only inside the collectComposedDatasourceConnectorErrors docblock (:4632-4638) and the template literals of the ambiguity arm (:4681-4687); ProvidedCollectionEntry (:4512-4546), providedCollectionEntries (:4567-4597) and the collector's signature (:4642-4645) are byte-identical to the previous head. No export, no .describe(), no authorable key, no generated artifact; check:api-surface rides the green Lint & Repo Gates. RIGHT.
2. Accept set of composeStacks: UNCHANGED, read off the code of this head. The slot expressions (:4589-4590, :4594-4595), the inBody derivation (:4595), the grouping by name then slot (:4653-4655), the kept entry per slot (:4664), the ambiguity condition (:4667), the inBodies count that picks the sentence (:4672-4674, :4678), the shadow arm (:4694-4706) and the datasource withholding (:4711-4716) are the previous head's byte for byte, and the previous head's were main's. The commit's diff to stack.zod.ts holds string content and nothing else. So the card's fourth task (no verdict moves in either direction) HOLDS on the code, and the commit message's claim is verified, not taken on trust. RIGHT.
3. Message text, the one published behaviour that moves again. Two package bodies: unchanged, still byte-identical to main's. A body beside a top-level entry: the reload half now reads "a dev reload replaces it with the artifact's top-level entries of the name, the first of which lends, so the entry the datasource borrows depends on whether the artifact was booted or reloaded and on the order of its inputs" (:4681-4683). Top-level entries only: now "No door registers either as a package body's entry, and a dev reload lends from the first top-level entry of the name, so the build cannot tell which one lends, and the datasource could boot with no credential" (:4685-4687). The remedy sentence is unchanged. RIGHT as a declaration; both sentences are judged in ④.
4. inBody derivation and the slot / inBody docblocks (:4516-4545): untouched by the delta; stand as judged in record 6519281283 ① items 4 and 5. providedCollectionEntries' docblock (:4548-4566): untouched, stands. The collector's docblock: the middle bullet and the third bullet now carry the ④-judged wording; the two-bodies bullet is unchanged. RIGHT.
5. The test file (no published surface): 30 cases (8 per-stack, 22 composed), up from 28: the mixed-input CONTROL (test :357-377) now asserts the artifact's connectors order in both input orders, and one it.each of two cases (test :379-397) pins the third sentence. Header (test :34-41) and the BOOT_OR_RELOAD constant (test :174-176) carry the new wording. Read to judge the fixtures and what the PR pins; lane seat's ACCEPT.
6. No generated reference moves (the tree was reported clean after the gate run and the required typecheck job that carries every spec gate is success); no docs page restates either sentence, as record 6519281283 ① item 7 found and the delta gives no new reason to doubt. RIGHT.

② Semver level

• .changeset/28006-composed-connector-ambiguity-reason.md: '@objectstack/spec': patch, line-initial Clause-②: no (message text only: ...) and Metadata-protocol: none, both matching the PR body; one ADR-0087 marker comment, not-required (no-migration-prescription), with its reason. The delta changes two prose sentences of its body only (the reload half of the beside-body paragraph and the top-level-only bullet), bringing each to the wording the message now carries; level, kind, declaration lines and marker are untouched. Check Changeset success twice on this head. CONSISTENT, as in record 6519281283 ②; the prose imprecision that record named for the lane seat is gone.
• Clause-②: no stands by ① item 2. Metadata-protocol none stands. No arm is declared, rightly.
• The changeset prose, re-read against the tree: "a dev reload replaces it with the artifact's top-level entries of the name, the first of which lends" HOLDS (④); "no door registers either as a package body's entry, and a dev reload lends from the first top-level entry of the name" HOLDS (④); "Where it applies" and "Unchanged" stand as judged.

③ Boundary flags

1. Delta request 6520193154's account, item by item against the tree: should-fix 1 wording is in the message (:4681-4683), the collector docblock (:4634-4635), the changeset and BOOT_OR_RELOAD (test :174-176), and the CONTROL pins ['sap_token_2', 'sap_token'] mixed first and ['sap_token', 'sap_token_2'] mixed last (test :371, :376): HOLDS. Should-fix 2's sentence is at :4685-4687 and its case is test :379-397 with com.acme.bundle (descriptor) and com.acme.kit (instance) over silent bodies com.acme.inner and com.acme.toolkit, plus the strict: false borrower, in both orders: HOLDS. "No slot, grouping or condition changed": HOLDS (① item 2). The dev's run counts (30 tests; 25 pass against main's stack.zod.ts and 5 fail only at their wording fragment) are the dev's; the verdict-stability claim is established here from the code, not from that run.
2. PR body flag ("Full review owed at the reviewer tier ... lands only after a full review at the reviewer tier and a CONTRACT_REVIEW_TIER contract review record PASS on the current head"): answered by this record, which under the 2026-10-29T19:39Z order is both. The body now names this head in its Verification section, states 30 tests, and quotes the two new sentences as the code carries them; it names no model (it says "the reviewer tier" and "the default tier"). Its ablation line honestly says it was measured on the previous head, before the two added cases.
3. open_questions: [] on the os-dev-report 6518764127: nothing to answer; the delta request adds none.
4. out_of_scope_findings 1 (a residual top-level connector reaches the metadata service and not the ObjectQL registry the lender reads at boot): stands as judged in record 6519281283 ③ item 3, HOLDS by reading, unmeasured; the cited runtime is byte-identical at this head, and the one main-side move since (the connector-mutation reconcile) does not change which registry the lender reads. The escalation stands: one card, domain:spec / area:data, on the epic PM, naming the boot path as the measurement to run first. The third sentence this delta adds is in fact true BECAUSE of that gap (④), which is one more reason the measurement is owed.
5. Card composeStacks connector check: say why a top-level connector beside package bodies is refused as ambiguous, and pin the preserve reading of a mixed nested input #28006 tasks against the tree: tasks 1, 2 and 4 stand as judged in record 6519281283 ③ item 4; task 3 (pin the preserve reading of a mixed nested input) is now pinned more tightly, with the kept top level's order asserted in both input orders (test :371, :376) beside the composed manifest.id and the package list.
6. Author objectstack-fleet[bot] through the relay (attribution to marchtian); head repo equals base repo; draft; branch claude/project-thread-683cod as claim 6517611093 names; the three files are inside the claim's file surface; the merge carry-over adds no file to the PR's net diff (3 files, +186/-24). No governed-register path in the diff; size well under the 3,000-line class.
7. The commit message of 1580237 carries the model-free trailer pair; it names no model. The previous should-fixes were routed onto this PR by the epic PM, as the delta request says, which is the card's own filing gate and not scope expansion: both fixes are wording and tests of the one hits file and its own test, inside the card's task list.

④ Design judgment

packages/spec/src/stack.zod.ts (hits; the schema face) — the delta judged against the same authorities as record 6519281283 ④, all byte-identical at this head: unclaimedTopLevel / claimedArtifactSlots / artifactItemSlot (metadata/plugin.ts :405-426, :335-359, :314-325), registerUnclaimedTopLevel (:1475-1498) and its two sinks, registerApp into the ObjectQL registry, captureReloadedConnectors / mergeDeclaredConnectorSources / readDeclaredConnectorItems (service-automation/plugin.ts :1890-1904, :539-557, :1938-1971), the lender's findDeclared (first item of the declared list whose name matches, connector-credential-source.ts :83-89) and lendRefusal (:99-119), and on the build side preservePackageEntries (:7071-7082), packagesCarryEveryInputCollection (:7133-7149), step 3 concatenation, step 3b (:7759) and step 8 (:7846-7852), selectManifest 'last' (:7015-7033).

• Should-fix 1, the beside-body sentence's reload half, on every shape that renders it. The mechanism: captureReloadedConnectors records the reloaded artifact's whole top-level connectors list; mergeDeclaredConnectorSources drops every registry item whose name the list declares (the body's booted entry among them) and appends the list in its order (:549-556); findDeclared walks that list and answers the first entry of the name. So after a reload the first top-level entry of the name lends, whatever it is. Under last on the card's shape ([nested(strictPair), owner(descriptor)], test :290-305) the top level holds the plain input's descriptor alone (the nested input's own top level was stripped by its inner preserve composition, pinned at test :267), so the first entry is the descriptor and the reload borrows nothing: the sentence HOLDS and names the right entry. Under preserve on the mixed shape (test :344-355), the artifact keeps the whole flattened list in input order (packagesCarryEveryInputCollection returns false at :7143 for an input that carries packages beside its own connectors, so step 8 deletes nothing), now pinned by the CONTROL in both orders (test :371, :376). Mixed first: the list is [descriptor, instance], the reload lends the descriptor, nothing to borrow. Mixed last: [instance, descriptor], the reload answers the top-level copy of the body's own instance, which lends. The sentence says the borrowed entry "depends on whether the artifact was booted or reloaded and on the order of its inputs": in the mixed-last order boot and reload both lend, from two different registrations of one instance, and the input order is exactly what decided it; in the mixed-first order they differ. It is true in both orders, no longer claims a credential-less reload where none happens, and the refusal still stands on the stand-in slot in both. The previous record's should-fix 1 is DISCHARGED, in the message, the collector docblock (:4634-4635), the changeset, BOOT_OR_RELOAD and the CONTROL's order pin.
• Should-fix 2, the third sentence and its pin. The new case (test :379-397): two inputs that each carry packages beside a same-named top-level entry (com.acme.bundle with the descriptor over a silent com.acme.inner body; com.acme.kit with an instance over a silent com.acme.toolkit body) and a strict: false borrower with a manifest and no connectors, under preserve, in both orders. Collector: each mixed input's body contributes nothing for connectors; each top level takes its own package:${id} slot with inBody: false (:4594-4595); the borrower's own slot holds no connector. Two kept entries, one lends, one cannot, inBodies is 0, the third arm renders, and the one datasource that names sap_s4 is withheld with that finding: exactly one issue, as expectComposedFinding asserts, with disagree naming 'com.acme.kit' (stack #N) as the lender and 'com.acme.bundle' (stack #M) as the entry that cannot (stackLabel, :6228-6231), matching the test's fragments in both orders. Runtime for the composed artifact: packages are [inner, toolkit, orders-assembled] (or reversed), the top level keeps [descriptor, instance] in input order (step 8 deletes nothing, as above), the composed manifest.id is the borrower's com.acme.orders (selectManifest 'last'). Boot: no body claims ('connector', 'sap_s4'), so unclaimedTopLevel lists both entries and registerUnclaimedTopLevel registers them under com.acme.orders through the door's sink into the metadata service; neither reaches the ObjectQL registry as a connector (the manifest service registers a residual's objects only), and the lender reads that registry plus the stored overlay (record 6519281283 ③ item 3). "No door registers either as a package body's entry" HOLDS literally (both are residual, registered under the composed id, not as any body's item), and "the datasource could boot with no credential" HOLDS (at boot nothing lends; were the metadata-service registration ever read, last-wins by name there would make it order-dependent, still unknowable to the build). Reload: the captured list is the top level in input order and findDeclared answers its first entry, so "a dev reload lends from the first top-level entry of the name" HOLDS: descriptor first, nothing lends; instance first, it lends. The sentence now states its mechanism the way the other two arms do, and it is pinned in both orders. The previous record's should-fix 2 is DISCHARGED.
• Nothing else moved in the hits file. The two-bodies sentence is still main's byte for byte, judged in record 6516406275 ① item 5 and again in record 6519281283 ④. inBody's doc, slot's doc and providedCollectionEntries' docblock are untouched and stand claim by claim as judged in record 6519281283 ④. The three judged-not-a-finding edges there (an id-less manifest under strict: false, packages: [] on a preserve input, the identity dedupe of a both-halves nested input) are unaffected by a wording change and stand. The acceptance note that the stand-in slot is load-bearing (judging the mixed top level in the composed manifest.id slot would ACCEPT [mixed(descriptor), strictPair]) stands; the delta does not touch the slot.
• Tried to break the new wording. (a) A last composition where the nested input kept both halves (bodies did not reproduce the flattened half) beside a plain input's same-named top-level entry: the top level then holds the nested input's copy and the plain input's entry in input order; the collector dedupes by object identity and keeps the body's entry (bodies first), so the finding is still one and still the middle arm, and the reload lends the first of the two top-level copies, which is what the sentence says. HOLDS. (b) Three or more top-level entries of the name under last, all in 'artifact': one slot, one kept entry (the last), so the ambiguity arm compares that one against the bodies; the reload lends the FIRST of the name while the collector judges the LAST. This is main's slot rule for the flattened top level (SAME_STACK_ENTRY_IDENTITY, the registry's later-wins within one slot), not this PR's: the sentence rendered there is still true of the reload, and the kept-entry choice is the pre-existing design, outside the card (no accept-set move). Judged, not a finding. (c) The third sentence under last: unreachable, as the previous record found, since every non-body entry shares 'artifact'; no false rendering possible. (d) A mixed input whose own body also declares the name: the body claims it at boot and the collector sees two slots (package:inner with inBody: true, package:bundle with inBody: false), so the middle arm renders and "the body's entry lends" HOLDS. No finding.
• The test group as it now stands: the renamed case asserts the envelope, one finding, both site labels, the boot-or-reload sentence and the absence of the old phrase; the mixed group asserts both refusal orders, the CONTROL pins the composed manifest.id, the package list and the kept top level's full order in both input orders, and the two-mixed-inputs case pins the third sentence with its site labels in both orders. Not run here; Test Core 1/8-8/8 success on this head.

Findings. No must-fix. No should-fix: the two should-fixes of record 6519281283 are discharged as that record asked, each sentence is true on every shape that renders it, and no verdict of composeStacks moves in either direction (read off the code at ① item 2). Escalation stands unchanged from record 6519281283 ③ item 3: one card for the residual top-level connector the lender cannot see at boot, which the third sentence now describes correctly and which remains unmeasured.

维护者速读

• 改了什么： 合成栈检查连接器同名「有歧义」时，拒收提示里的原因改成按条目实际所在位置来写。两个包体同名、包体旁边有同名顶层条目、只有多个顶层条目，这三种情况各配一句，分别说清开机时哪一条出借、开发态重载后哪一条出借。拒收结论没有变化。
• 为什么改： fix(spec)!: composeStacks refuses a datasource whose external.connector names no connector instance the composed inputs declare #27939 的复核发现，原来那句「运行时每个包保留一条」放在「包体旁有顶层条目」这种情况下不成立。结论是对的，理由是错的，作者会被误导去改错声明。
• 风险与回滚： 只改提示文字、注释和测试，接受集不变（Clause-②: no）。新测试用 main 上的 stack.zod.ts 跑，只有措辞断言失败。还原即可回滚。
• 先看： packages/spec/src/stack.zod.ts 的 collectComposedDatasourceConnectorErrors 文档和 where 三分支。
• 两分钟验证： pnpm --filter @objectstack/spec exec vitest run src/stack-datasource-connector.test.ts。
• 需要你做的： 无，席位落地。

席位意见：ACCEPT。契约复核 PASS 已在案：6519281283 在 55b0c856 上通过，附两条 should-fix；delta 6520726439 在当前 head 541d7f5b 上为干净 PASS，均为 CONTRACT_REVIEW_TIER。Fable 额度仍未恢复，按 2026-10-29 19:39Z 的指示，这份记录同时充当 spec 改动的完整复核。无 must-fix。

席位核对

1. Shape: +186/−24 across 3 files: the ambiguity sentence's three arms and their docblocks in stack.zod.ts, the tests (30, including two-order preserve cases for the mixed shapes), and an @objectstack/spec patch changeset.
2. Premise measured: the reviewer read the boot path (unclaimedTopLevel) and the reload path (mergeDeclaredConnectorSources) at origin/main and confirmed each arm's mechanism (record 6519281283 ④).
3. Gate check-runs on 541d7f5b: 53 runs: 41 success, 12 skipped, 0 failed. Local: 80 derived gates, all exit 0.
4. Accepted deviations: none. The PR body is patched to this head's counts and sentences.
5. Out of scope, routed: the residual top-level connector the lender cannot see at boot (record ③ item 3) is filed as A connector a mixed composed input declares only at its top level beside package bodies is invisible to the lender at boot, yet the composed check accepts a borrow of it #28032. The fix is PR fix(objectql): a connector a composed stack declares only on its top level, beside package bodies, lends its credential at boot #28046 (objectql). After it lands, the boot registers residual connectors under the composed id, and the third arm's sentence still holds: none registers as a package body's entry. The related residual flows finding is filed as A flow a composed stack declares only on its top level, beside package bodies, is never registered with the automation engine at boot — the manifest service registers the residual's objects and connectors only #28048.
6. Landing: not governed (check-governed-merges --pr 28026; 210 lines ≤ 3000). A same-shape PASS stands on the current head, so needs:contract-review comes off. The seat lands it through the relay.
