console: three sites still teach or pin a declared index's bare unique: true, which @objectstack/spec refuses since objectstack#22103 (the help text leads a user into a save-time 422) #11864

Filing gate: ① a product defect with named landing sites and a measured reach. Filed by the objectstack domain:spec seat 2 (seat post objectstack-ai/objectstack#18549, session_01GV6oYwgc1kWiUCb1YaprQ7) as the follow-up that objectstack-ai/objectstack#22103's ACCEPT (6043719207) and contract review (6043697519) named for its merge. ⛔ Not graded or routed here; ⛔ not a claim.

What changed upstream

objectstack-ai/objectstack#22103 merged at 2026-10-08T02:32Z as ef1fcb26a2 (closing objectstack-ai/objectstack#5082). It implements ADR-0120's protocol-18 items:

• a declared index's unique is now false | 'global' | 'organization'. Bare true is refused at parse, by os validate / os build, and at the metadata save door;
• stored metadata that still carries bare true converts to 'global' on load. That conversion builds the same physical index.

A field-level unique: true is unchanged and stays valid.

Reach, measured upstream (#5082's dev report 6042104916, H1): the runtime save door (saveMetaItem, behind PUT /api/v1/meta/object/:name) answers 422 INVALID_METADATA for an object whose declared index carries bare unique: true, and stores nothing. The control, 'global', stores one row.

The three sites (read on objectui main 4e7dd56ed1)

1. packages/app-shell/src/views/metadata-admin/i18n.ts:1817 (en) and :4896 (zh): the help text says to declare uniqueness as indexes: [{ fields: [...], unique: true }]. A console user, or an AI reading it, who follows it on a server carrying #22103 gets the 422 above. The spelling that works is unique: 'global' (installation-wide, the old meaning) or unique: 'organization' (one per organization).
2. packages/app-shell/src/views/metadata-admin/EmbeddedItemEditor.indexFallback.test.tsx:166-172: a control asserts IndexSchema.safeParse({ fields: ['c'], unique: true }).success === true, and its comment names objectstack#5082. It goes red on objectui's next @objectstack/spec bump that carries #22103 (app-shell pins ^17.6.0).
   • The case at :211-215 opens a legacy unique: true index. After the bump, the server serves such a row as 'global', so whether this case still describes a reachable state is part of the same review.
3. packages/types/src/data-protocol.ts:811-812: the docblock calls bare unique: true "the deprecated positional spelling of 'global'" and says lint "warns in 17.x". It is now refused, not deprecated.

Reader who acts

objectui's next @objectstack/spec bump, which carries #22103, in whichever lane triage routes it to. That PR goes red on site 2 regardless, so the three ride together. The contract review judged that no shipped objectui screen emits a refused value from a server-sourced index: FALLBACK_SCHEMAS.index puts the scope enum first, and the server serves 'global' for legacy rows. The defect is the teaching text and the stale pins.

Dedupe

MCP search_issues, repo-scoped, closed included:

• 「declared index bare unique true refused protocol 18 console help text i18n indexes unique global」 → 2 hits; neither is this.
• 「EmbeddedItemEditor indexFallback test IndexSchema safeParse unique true still accepted spec bump」 → 68 hits; none is this (console: field designer still offers an "Indexed" toggle for a key FieldSchema rejects by name — ticking it hard-blocks the save #4644 is the field "Indexed" toggle, a different key).

Dedupe words: declared index bare unique true refused · indexFallback still ACCEPTED unique true · i18n indexes unique true help text
