`UniquenessValidation`'s deprecation JSDoc points authors at the retired `indexes[].partial` key

[os-zhuang]

Found while converging the console's index fallback schema for objectstack-ai/objectstack#5247 (PR touches EmbeddedItemEditor.tsx only; this sits outside that card's declared file surface, so it is filed rather than fixed).

What

packages/types/src/data-protocol.ts (~line 1013), on the @deprecated tag of UniquenessValidation:

 * @deprecated The spec removed this deliberately: a SELECT-then-INSERT check is
 * racy (TOCTOU) where a DB constraint is not. Declare a unique **index**
 * (`ObjectSchema.indexes`, `{ fields, unique: true }`, `partial` for a scoped
 * constraint) or field-level `unique: true` instead.

Two of the three spellings it prescribes are no longer correct:

• partial was RETIRED in @objectstack/spec 17.0.0 (ADR-0049 enforce-or-remove:IndexSchema.type 与 IndexSchema.partial 没有任何 DDL 消费者 objectstack#5248, ADR-0049 enforce-or-remove, maintainer ruling 2026-08-06). It is a retiredKey tombstone in IndexSchema today, so the parse rejects it at any value. Measured against the installed @objectstack/spec@17.0.0-rc.6:

  IndexSchema.safeParse({ fields: ['a'], partial: "s = 'open'" })
  // success: false — "`indexes[].partial` was removed in @objectstack/spec 17.0.0 …"
  

  A scoped/partial unique constraint is now built at the database layer by a runtime migration issuing CREATE UNIQUE INDEX … WHERE, not declared.

• unique: true is the DEPRECATED positional spelling of unique: 'global' under ADR-0120. Lint unique/unscoped-declared-index warns on it in 17.x and protocol 18 rejects it (ADR-0120 协议 18 项:D2 conversion(声明索引 unique: true → 'global')+ 裸 true 硬拒 + synonym pin 退役 —— 挂 18 列车,现在勿动工 objectstack#5082). The prescription should state the scope: unique: 'global' or unique: 'organization'.

Why it is worth fixing

This is guidance that claims more than the platform delivers — the class objectstack-ai/objectstack#5247 calls out explicitly, citing the strictness ledger's finding 18 (four pieces of false guidance already shipped in that campaign). It sits on a @deprecated tag, i.e. precisely the text an author reads at the moment they are migrating off the old shape, so the wrong spelling is maximally likely to be copied.

The interface itself is correctly deprecated and unreachable from the server (ValidationRuleSchema rejects type: 'unique') — only the replacement advice is stale. A comment-only change; no runtime behaviour.

Suggested shape

Rewrite the @deprecated prescription to { fields, unique: 'global' | 'organization' }, drop the partial clause, and point partial constraints at the database-layer migration route.

Triage first-touch grade (concentrated batch; triage seat, session session_01NYoiJGd1MxXdcvM4EGAMrS): promoted to pm:queue, type Bug — false guidance on a @deprecated tag is the worst place for it (read at exactly the migration moment), and both wrong spellings are measured: partial is a retiredKey tombstone in spec 17.0.0 and unique: true is the deprecated positional form under ADR-0120. Comment-only fix, suggested shape in the body stands (unique: 'global' | 'organization', point partial constraints at the DB-layer migration route). Claim-time note: re-verify the prescription against the installed spec at that moment (the card measured rc.6; GA is pinned now). Size/model suggestion: S, sonnet.

Claim. PM seat domain:ui (seat post #5560), round 7. Session session_012u2pRjcqAYtoEjgr3wwhnK. Branch claude/issue-4765-uniqueness-deprecation-jsdoc. pm:queue → pm:dispatched.

Scope. The @deprecated prescription on UniquenessValidation in packages/types/src/data-protocol.ts.

Why this one is graded Bug rather than tidy-up. False guidance on a @deprecated tag is read at exactly the moment an author is migrating off the old shape, so a wrong spelling is maximally likely to be copied. Two of the three spellings it prescribes are wrong today: indexes[].partial is a retiredKey tombstone the parse rejects at any value, and unique: true is the deprecated positional form under ADR-0120 that lint warns on in 17.x and protocol 18 rejects.

Re-measure against the installed spec before wording the replacement. The card measured 17.0.0-rc.6; GA 17.0.0 is pinned now. Run the parse yourself and quote what it says — a tombstone message is the kind of thing that gets reworded between releases, and this card is about guidance that stopped matching the platform.

Suggested shape, subject to your measurement: prescribe { fields, unique: 'global' | 'organization' }, drop the partial clause, and point scoped/partial constraints at the database-layer migration route (CREATE UNIQUE INDEX … WHERE) rather than at a declarable key.

Do not touch the interface's own deprecation. UniquenessValidation is correctly deprecated and unreachable from the server (ValidationRuleSchema rejects type: 'unique'). Only the replacement advice is stale.

Fence note. Another round-7 card (#4611) is editing packages/types/src/ui-action.ts. Different file in the same package — no overlap, stated explicitly because "same package" is not the collision unit. Stay out of ui-action.ts.

Prose only — no runtime behaviour. If your diff touches anything that emits JavaScript, stop and report.
