Fixes #4594

Converges the second dual declaration living in the same two files as SchemaNode onto the one declaration in @object-ui/types, per triage's ruled scope and the #4580 / PR #4608 precedent sitting two lines above it in the same file. The ⛔ "Deliberately NOT reconciled … stays dual-declared until #4594 is dispatched on its own evidence" marker comes out in the same diff — main was waiting on this card.

  • packages/core/src/types/index.ts — the local non-generic interface ComponentRendererProps { schema: SchemaNode; [key: string]: any } becomes export type { ComponentRendererProps } from '@object-ui/types'. The import type { SchemaNode } line above it goes with it: the deleted interface was its only reader.
  • packages/react/src/__tests__/ComponentRendererProps.reconciliation.test.ts — new compile-time pin, beside the SchemaNode one, in the only position that resolves both packages through node_modules.

Third convergence across this fault line, after SchemaNode (#4580) and ComponentInput (#4972 / PR #5671).

Obligation 1 — zero consumers, re-verified on the merged ref

Re-run rather than inherited from the card, repo-wide on d7573b3f4 (grep -rn ComponentRendererProps, excluding node_modules / .git / dist). Five hits, zero of them a consumer:

hit what it is
packages/types/src/base.ts:341 the generic declaration
packages/types/src/index.ts:93 types' own entry re-export
packages/core/src/types/index.ts:46,53 the ⛔ marker + the non-generic declaration
packages/core/src/index.ts:9 core's own entry re-export
packages/components/CHANGELOG.md:1725 prose, recording "21 occurrences … against zero uses of ComponentRendererProps"

No import on either side, so the mechanical disposition stands and nothing downstream can observe the shape move measured below.

Obligation 2 — the surface measurement, and the gauge this PR refuses to use

core/dist/index.d.ts byte-identity is not cited as evidence here. packages/core/src/index.ts is a 95-line export * barrel naming neither symbol, so the emitted core/dist/index.d.ts is byte-identical under any change to a re-exported module and is incapable of failing for this change class — #5673, filed off #5671's control leg. It came out byte-identical again this round (f6494f80… on both legs, the same hash #5671 recorded), and that is reported as a control, not as a result.

Both legs built from a fully cleaned state: dist/ removed and every tsconfig.tsbuildinfo swept repo-wide. The sweep is load-bearing — those files live at packages/core/tsconfig.tsbuildinfo and packages/types/tsconfig.tsbuildinfo, i.e. outside dist/, so wiping dist/ alone leaves composite tsc skipping emit and compares two stale trees for free. Measured: the CHANGE leg swept exactly those two. Compared by sha256, never by byte count.

Whole-tree .d.ts sha256 manifests over packages/core/dist + packages/types/dist145 files on each leg, exactly one differs:

emitted file BASE CHANGE verdict
core/dist/types/index.d.ts 893cb23b… 0e64c8c6… changed
core/dist/index.d.ts f6494f80… f6494f80… byte-identical — the vacuous gauge
the other 143 unchanged

What the published surface actually does

Reachability and shape resolved through the TypeScript checker (checker.getExportsOfModule on each package's entry .d.ts, then aliases followed to the declaration), never grepped — export * propagates a symbol without naming it, so a grep in a barrel proves nothing.

ComponentRendererProps as reached through @object-ui/core:

leg type parameters schema resolves to declaration home
BASE none (non-generic) BaseSchema | string | number | boolean | null | undefined packages/core/dist/types/index.d.ts
CHANGE TSchema extends BaseSchema = BaseSchema TSchema (default BaseSchema) packages/types/dist/base.d.ts

So this change does move the resolved shape, in two ways, and the declaration home collapses to the single site shared with @object-ui/types:

  1. schema narrows — from the SchemaNode union back to the object form. Core's copy had silently widened when PR fix(types): one SchemaNode and one label vocabulary — the union wins, labels resolve where the locale lives (#4580) #4608 made core's SchemaNode a re-export of types' union; the card predicted that side effect and it happened. This closes the interim state rather than creating one.
  2. The type gains a parameter, so a call site can pin schema to its own BaseSchema sub-interface through core's name.

Can anything downstream see it? No — Obligation 1: nothing imports the type, on either side. The narrowing is declared in the changeset because it is a change to a published type, not because a consumer is affected.

Ablation — direction predicted before running

Predicted RED: restore core's hand-declared interface, rebuild, and the new pin must fail with (1) TS2344 where Equal<> resolves false, (2) TS2315 Type 'ComponentRendererProps' is not generic wherever a type argument is applied to core's name, (3) TS2322 at const node: TextSchema = props.schema. The tsc --noEmit half over src was predicted to stay green (no source consumer).

Observed — pnpm --filter @object-ui/react type-check exit 2, five errors:

ComponentRendererProps.reconciliation.test.ts(81,34): error TS2344: Type 'false' does not satisfy the constraint 'true'.
ComponentRendererProps.reconciliation.test.ts(85,41): error TS2315: Type 'ComponentRendererProps' is not generic.
ComponentRendererProps.reconciliation.test.ts(86,34): error TS2344: Type 'false' does not satisfy the constraint 'true'.
ComponentRendererProps.reconciliation.test.ts(100,16): error TS2315: Type 'ComponentRendererProps' is not generic.
ComponentRendererProps.reconciliation.test.ts(114,20): error TS2315: Type 'ComponentRendererProps' is not generic.

(1) and (2) landed as predicted, 2× and 3×. The src half stayed green — && short-circuits, so the test project could only have run because it passed.

(3) did not appear, and the prediction was wrong rather than the leg void. TS2315 resolves the offending type reference to the error type, so props is poisoned to any and the assignment underneath it is never checked: the third error is absorbed by the second, not additive. Reported as observed.

Both legs rebuilt (tsconfig.tsbuildinfo swept, types then core), and the mutation confirmed on disk and in dist/ on each leg by anchored greps rather than by an editor's exit code — mutation leg: local interface present 1 / re-export absent 0 in both src and dist; restore leg: the inverse, 1 / 0. The script carried trap restore EXIT INT TERM so a killed run could not leave the tree mutated. Restore is provably byte-identical to the commit: git status --porcelain empty, and the rebuilt core/dist/types/index.d.ts re-hashes to 0e64c8c6…, the CHANGE-leg value.

Tests and gates

All against the final commit, 641dcea68.

  • New pin, pnpm exec vitest run packages/react/src/__tests__/ComponentRendererProps.reconciliation.test.tsTest Files 1 passed (1) / Tests 1 passed (1), exit 0.
  • Affected packages, pnpm exec vitest run --maxWorkers=2 packages/core/ packages/types/ packages/react/Test Files 187 passed (187) / Tests 3110 passed (3110), exit 0.
  • pnpm --filter @object-ui/react type-check (tsc --noEmit && tsc -p tsconfig.test.json) — exit 0, after building react's dependency closure (--filter '@object-ui/react^...' build, exit 0).
  • Gates, each read from its own printed verdict line, exit code captured before any pipe: check-changeset-presence ✅ · check-changeset-fixed ✅ · check-changeset-no-major ✅ · check-control-bytes ✅ (4724 tracked text files) · check-type-check-coverage ✅ · check-lint-coverage ✅ · check-package-self-import ✅ · check-phantom-dependencies ✅ · check-doc-component-types ✅ · check-skills-paths ✅.
  • check:eager-closure, check:doc-snippets, check:published-dist not run locally — known-broken/over-cap in this container; CI owns all three.

Lint was narrowed deliberately, and the narrowing is measured rather than assumed. ① Population read from eslint's own config, not guessed: ESLint#isPathIgnored over git ls-files says 3526 of 3528 tracked source files are in scope. ② Files actually linted, read from --format json: 2 — exactly the two this diff touches, 0 errors, 0 warnings, exit 0. ③ Invariance for the untouched 3524: eslint.config.js declares no projectService and no parserOptions.project (no type-aware rules), no custom rule in eslint-rules/ reads any file other than the one being linted (readFileSync/readdirSync/globSync: zero hits), and this diff does not touch the config — so each other file's verdict is a function of its own unchanged text and the unchanged config. CI runs the full farm regardless.

…ating it

core hand-declared a non-generic `ComponentRendererProps` typing `schema` as
`SchemaNode`, against `@object-ui/types`' generic
`ComponentRendererProps< TSchema extends BaseSchema = BaseSchema >` — the second
such pair in the same file, two lines below `SchemaNode`. Core's becomes a
re-export, per objectui#4580's ruling for the identical shape and objectui#4972
for `ComponentInput`, and the deliberate "not reconciled" marker comes out with
it.

Zero consumers re-verified repo-wide on the merged ref, not inherited from the
card. The re-export is NOT surface-neutral: resolved through the TypeScript
checker from core/dist/index.d.ts over a clean rebuild of both legs, `schema`
narrows from the `SchemaNode` union back to `TSchema` (default `BaseSchema`) and
the type gains a parameter. `core/dist/index.d.ts` byte-identity is not cited as
evidence — it is an `export *` barrel and cannot fail for this change class
(objectui#5673).

A compile-time pin in @object-ui/react, the only position resolving both
packages through node_modules, holds the reconciliation.

ACCEPT — reviewed by the domain:ui execution seat

Session session_012u2pRjcqAYtoEjgr3wwhnK. Triage's ruled scope is discharged exactly: core's local declaration deleted and re-exported, the ⛔ marker at packages/core/src/types/index.ts:46-52 removed in the same diff, zero consumers re-verified rather than inherited. No open questions. Landing on green.

The thing this card was really a test of, and you passed it

#5671 landed 35 minutes before you started, and #5673 came out of it: the "core/dist/index.d.ts is byte-identical" justification is a gauge that cannot fail. Your card sits in the same file as that docstring, and the obvious move was to reach for the same measurement and bank the same green.

You didn't. You reported f6494f80… unchanged as a control, never as evidence, and then went and found the emitted file that can move for this change — core/dist/types/index.d.ts, 893cb23b…0e64c8c6…, one file differing out of a 145-file whole-tree manifest. That is a third independent confirmation for #5673, and I've recorded it there.

A refinement your result forces — on something I wrote, not you

I generalised #5671's finding into this lane's seat post as: "core/src/index.ts names the symbol zero times, so that file is byte-identical under any change to a re-exported module."

That reasoning does not cover your card, and I checked because your result looked like it should have contradicted it. core/src/index.ts:9 is one of the barrel's two named lines:

export type { SchemaNode, ComponentRendererProps } from './types/index.js';

So the barrel does name your symbol — and is byte-identical anyway. The correct rule is broader than the one I wrote, and simpler:

A barrel is byte-identical under any change to a re-exported declaration's shape, whether or not it names the symbol — because neither export * nor export type { X } from '…' restates X's shape.

Mine was true of #5671 and accidentally narrow. Yours is the case that shows why. Recorded on #5673; the seat post gets it at this round's close.

The wrong prediction, and why the way you handled it is the point

You predicted TS2344 ×2, TS2315, and TS2322 at the narrowed read. You observed 2× TS2344 + 3× TS2315 and no TS2322 — then diagnosed it instead of shrugging:

TS2315 resolves the offending reference to the error type, so props is poisoned to any and the assignment underneath is never checked — the third error is absorbed by the second, not additive.

And the sentence that matters: "That prediction was wrong, not the leg void."

Those are different failures and conflating them is how a broken instrument gets excused as a bad guess, or a bad guess gets escalated into a rerun. A void leg means the measurement didn't happen. A wrong prediction means it happened and taught you something. You had a genuine reason to reach for "void" here — this lane has a standing rule about reporting void legs — and you correctly didn't, because the leg did discriminate; only your model of the error cascade was off.

The narrowing, and why it is clause ② cleared

This change is not surface-neutral, and you said so rather than letting "re-export instead of restate" imply it was. Resolved through the checker: schema goes from the SchemaNode union (BaseSchema | string | number | boolean | null | undefined) to TSchema extends BaseSchema = BaseSchema, i.e. narrows back to the object form, and the type gains a parameter.

Two things I verified myself before ruling, because "gains a parameter and narrows schema" is exactly the phrasing that could hide a larger change:

  1. The index signature survives. Both declarations carry [key: string]: any. Had types' version lacked it, this would have been a far bigger narrowing than the one reported — every extra prop on a renderer's props object would become an error. It doesn't.
  2. Zero consumers, independently. Six occurrences repo-wide excluding node_modules/dist: two declarations, two entry re-exports, the marker comment, and one CHANGELOG line — which, pleasingly, is packages/components/CHANGELOG.md:1725 recording "21 occurrences across the renderer tree, against zero uses of ComponentRendererProps". The repo's own history corroborates the census.

Clause ② is cleared on the derived-from-an-authority line. The pre-change shape was not an intended contract: core's copy silently widened when #4608 landed, because its schema: SchemaNode began resolving through the new re-export to the union. #4594's own card predicted precisely that — "the interim state is the worst of both" — so this narrowing is the repair of drift the card was opened to catch, not a new contract decision.

One caveat recorded for completeness, the same one #5674 raises: "no importer in this repo" and "no importer" are different claims, and only the second fully licenses a narrowing on a published surface. External consumers cannot be enumerated from here. It does not change the ruling — the shape being narrowed to is the one @object-ui/types has published all along, and the union was the accident — but it should be stated rather than glossed.

The compile-time pin in @object-ui/react is the right home: it is the only position that resolves both packages through node_modules, so it is where a future divergence would actually be observable.

Operational

Noted and appreciated: the shared verify lock returned 99 (queue-timeout, 9m00s, never acquired) behind #4482's holder, and you spent the interval on lock-free work — gates, eslint, evidence — then retried and acquired at 4m38s. "Nothing was measured unlocked." Five agents share one box; that is the behaviour that keeps a sibling's run from surfacing in their task as an inexplicable flake.

Landing

Flipping ready and enqueuing at 19 success + the 3 always-skipped no-ops, read by name. Worth knowing while you wait: per #4986 the merge queue's required set does not include the shards, Type Check or Lint, so that by-name read is the only gate under this PR — there is no backstop.
