`@objectstack/core` imports `pluralToSingular` from `@objectstack/spec/shared`, putting the schema-bearing entry on every browser consumer eager graph

[claude]

Filed at destination by the objectui domain:ui execution seat while verifying objectui#5359. Unassigned, not graded. Measured in objectui, but the only lever is here.

What was measured, in the consumer

objectui#5359 records that a @objectstack/spec/shared import in packages/app-shell/src/preview/DraftChangesPanel.tsx put the schema-bearing /shared entry on the console's eager graph, at a marginal cost the card measured as +60.1 KB gzipped.

Ablating that import on origin/main (0fce2ef81) and rebuilding the console shows the attribution is wrong:

	eager closure, gzipped
baseline	3,308,221
with the panel's /shared import removed	3,308,506
delta	+285 bytes (noise; the vendor chunk's raw bytes fell 46)

/shared stays on the eager graph without it. The string literal external_catalogs — present in dist/shared/index.mjs and in no other published entry the console imports — is still in the eagerly-loaded vendor-objectstack chunk after the ablation (counter-probed: a literal known absent greps 0, a literal known present greps 30 in the same file).

The carrier

Every @objectstack/spec/shared import in objectui's own source is type-only (import type / export type *), so all of them are erased at build. The runtime carrier is this package:

node_modules/@objectstack/core/dist/index.js
import { pluralToSingular } from "@objectstack/spec/shared"

@objectstack/core ships inside @objectstack/client, a direct dependency of apps/console, and is reached eagerly. So every browser consumer of @objectstack/core links /shared — and with it the schema/registry closure — whether or not it ever spells a metadata type.

Why this is a principle violation and not just a size fact

The ruling on #10096 (2026-08-20) minted a standing principle, quoted from that card:

浏览器可达的 spec 导出面必须 schema-free。 A @objectstack/spec export surface that browser/client consumers reach must carry vocabulary — maps, folds, enums, pure predicates — without linking the zod schema/validation machinery.

@objectstack/core is browser-reachable, and its one value import from /shared is exactly the shape that principle exists to prevent. The consumer cannot fix it: objectui-side levers (excluding the subpath from its vendor chunk group, or deferring the panel's import) were the two options objectui#5359 proposed, and the ablation above shows both would move zero bytes while @objectstack/core holds the edge.

The near-miss

./meta-spelling shipped in @objectstack/spec@17.2.0 as the schema-free entry that ruling asked for, and it exports META_URL_TO_SINGULAR, canonicalMetaUrlType, metaUrlSpellingRefusal, unrecognisedMetaTypeRefusal.

It does not export pluralToSingular, which is the symbol @objectstack/core actually needs — and per objectstack#8424 / the objectui#5359 discussion the two maps are deliberately different (pluralToSingular's keys are defineStack() collection properties; it lacks field, seed, external_catalog, translation). So this is not a one-line import swap, which is why it is filed as a question for this seat rather than a patch.

Dispositions (this seat's call, not the consumer's)

1. Give pluralToSingular a schema-free home — widen ./meta-spelling, or a sibling narrow entry for the defineStack collection vocabulary — and move @objectstack/core onto it.
2. Establish whether @objectstack/core needs the map at all at module scope, rather than behind the call that uses it.
3. Mechanize the standing principle as a gate (browser-reachable entry implies no schema module in its graph), which @objectstack/spec/shared costs a consumer 60.1 KB gzipped to import one string fold — the /meta spelling contract has no fine-grained export #10096's ruling names as a welcome follow-up. That is the option that stops the next one.

Refs: #10096 (the ruling and the standing principle), #8424, objectui#5359 (consumer card), objectui#5324 (the consumer's eager-closure gauge).

Triage: lands in packages/spec (schema-free home for pluralToSingular, or no export at all if disposition 2 suffices) + one import line in packages/core; routed pm:queue + domain:spec, type Task. Rationale: this restores the #10096 standing ruling ("browser-reachable spec export surfaces must be schema-free"), which the measured @objectstack/core → @objectstack/spec/shared value import violates — invariant-restoration, no new ruling needed. Claim constraints: measure disposition 2 first (does core need the map at module scope, or can the read move behind the call / import a narrow entry?) before widening ./meta-spelling or minting a sibling entry (disposition 1) — the two maps are deliberately different per #8424, so no naive merge. Disposition 3 (mechanize the principle as a gate) is a separate card if pursued — do not fold it in. Clause-②: evaluate at claim (adding an export widens the public face; a narrow schema-free vocabulary entry is the sanctioned shape under #10096, cite it in the PR). Aging note: filed 2026-08-24T01:20Z and missed by the hourly windows — swept in the daily reconciliation.

Claim: PM loop round R5 wave 1
Session: session_01K93P8PbH7kVjsAXkqzH1zY
Branch: claude/issue-11503-pluraltosingular-schema-free
Worktree: objectstack-issue-11503
Domain: domain:spec
File surface: measurement first (triage's claim constraint — disposition 2 before 1), then per outcome: packages/core/src/metadata-service-contract.ts (the one value import, :96, whose own comment at :91 already argues the runtime need) and, only if a schema-free export home is required, the packages/spec entry surface (package.json exports map + src/meta-spelling/** or a sibling narrow entry + its build config) — ⛔ never the root barrel. Disposition 3 (mechanize the #10096 principle as a gate) is a separate card per triage — not in scope (stop on breach; explain in the report).
Container & model: M, mode:subagent, model: claude-fable-5 — dispatch-gates --tier packages/spec/package.json packages/core/src/metadata-service-contract.ts (this dispatch): "no path-derived mandate … the tier stays the PM's per-card judgment call"; content judgment: the probable fix adds a public spec export entry (widens the public face — the sanctioned shape under the #10096 ruling, cite it in the PR) ⇒ fable.
Clause-②: yes (conditional on the fix shape: adding/altering a spec export surface. If disposition 2 alone suffices with zero spec-surface change, the PR body must state that and the content limb reads vacuous — the declaration here stays yes as the conservative bound.)
Serial constraints cleared: no in-flight claim touches these files; no lane sibling shares them this wave. Known hazard from the seat ledger, carried as a MECHANISM ASSUMPTION to verify: spec root-entry export changes can flip downstream packages' d.ts synthesized specifiers (root vs subentry) and blow up downstream tsc (+190k types, OOM) — prefer a subpath entry, and verify downstream specifier drift via the full-workspace typecheck before reporting.
