platform-checklist: add studio-authoring.picklist-bound-select, the acceptance item of objectui#10202 (a package picklist bound from the designer: forms offer its options, inline options are refused, an object with a bound field saves)

Routed by the objectui domain:ui seat 1 (session_015W8GBu6sBiqus2L2xjMsAL) as the cross-repo half of objectstack-ai/objectui#10202. Filed unassigned and unlabelled: routing and grading are this repo's triage's. ⛔ Not a claim.

Why

The ruling. objectui#10202 is the objectui half of spec: a shared picklist (global value set) metadata kind — option lists reused across objects and packages are TypeScript constants today #18164 phase 2. The director ruling 6006062645 there (batch 🔗 Broken links detected in documentation #280 item 1, letter A′, on the maintainer's order) scopes it to:
- (a) "use picklist" in the object designer's select-field editor;
- (b) the field save path dropping the served, resolved options when picklist is set;
- (c) a read-only picklist page;
- (d) "one studio-authoring checklist item".
Why it is filed here. (d) lives in this repo (docs/qa/platform-checklist/areas/studio-authoring.json), outside the objectui lane, so the seat carries it here instead of editing objectstack from an objectui card.
The objectui work. (a)–(c) are in PR feat(app-shell): Studio uses shared picklists — select-field picker, served options left out of object saves, read-only picklist page (objectui#10202) objectui#11669 (head 3114a9f), being landed through objectui's merge queue as this card is filed.
How the item was drafted. The card's dev drafted the entry below and matched it to what that PR built and measured live, on objectstack main faf8dce4 with a local, uncommitted picklist fixture:
- before: 422 INVALID_METADATA at fields.tier.options;
- after: 200 in both designers;
- both objects' forms offer the list's options, the extension's included.
Its fixture. The stock showcase declares no picklist, so the fixture line says so.

Notes for whoever authors it

Run order. The pnpm objectui:refresh fixture line has to hold before a run can pass: the console under test must carry objectui#10202's build.
A writer that still fails. One object writer the PR does not touch still re-sends the served options: Studio → Access → OWD overview. It is filed on the objectui side as its own card. This item's steps go through the two designers objectui#10202 fixed, ⛔ not through the OWD overview.

Dedupe: mcp__github__search_issues (objectstack-ai/objectstack, semantic, closed included), studio-authoring checklist item picklist bound select field designer forms options inline refused PUT round trip → 14 hits. None is this item. The nearest are objectstack#18164 (the epic), #19518 and #19519 (its spec and runtime halves, closed), and #20939 (a different studio-authoring item).

Triage: lands in docs/qa/platform-checklist/areas/studio-authoring.json ⇒ domain:devx; rationale: docs/qa/** is domain:devx's, and this is the checklist half (d) of the director's ruling on objectui#10202 (6006062645, letter A′).

Read now:
- the feature PR objectui#11669 merged (2026-10-06, 06:47Z);
- studio-authoring.json on main has no picklist-bound-select yet.
Why p3: the acceptance item for a landed feature. The checklist enters the queue as a docs disconnect, and nothing is red without it.
Done when:
- The entry in the card's body lands as drafted, revision: 1. The dev re-checks two things against what objectui#11669 shipped:
  - that the since value matches the release the feature first ships in;
  - that the fixture recipe (a package picklist plus one extension, uncommitted) is reproducible from the item's text alone.
- The checklist's own schema and lint checks pass.

"summary": "Appended studio-authoring.picklist-bound-select (rev 1, P2, surface mixed) as the last item of docs/qa/platform-checklist/areas/studio-authoring.json. No existing item or index moved, and coverage.json is untouched. SINCE = v17.7. 17.6.0 shipped 2026-10-02 (every @objectstack/*@17.6.0 tag derefs to 617f25f). objectui PR 11669 merged 2026-10-06 as objectui c3623eb1, after that release. No 17.7 tag exists. Of 315 pending changesets, 146 are minor and 0 major, so the next release is 17.7. The sibling item access-security.public-form-withdrawal-layers (PR 21964) uses v17.7. Condition: the feature ships in 17.7 only if .objectui-sha moves past c3623eb1 before the 17.7 cut; otherwise since needs a rev-2 bump to the release that does carry it. CONSOLE PIN: the pinned console does NOT carry objectui 11669. On objectstack main 80f9f7e the .objectui-sha pin is 0abd4f9f. In the shallow objectui checkout, merge-base --is-ancestor c3623eb1 0abd4f9f exits 1. The control leg (0abd4f9f~30, b65aa5e, against 0abd4f9f) exits 0. The reverse is also proven: 0abd4f9f is an ancestor of c3623eb1, exit 0, 21 commits behind. So the fixture line asking for pnpm objectui:refresh is load-bearing. CHANGES FROM THE DRAFT, each with its reason: (1) since v17.6 to v17.7, as above. (2) acceptance clause 3 split into a dom clause (picker vs GET /meta/picklist) and an api clause (the PUT body). Reason: its oracle "mixed" is not in the gate ORACLES set (api, network, screenshot, dom, log, test, build), so the drafted entry would red check:platform-checklist. Clauses 4-7 shift by one index; rev 1 has no runs yet. (3) fixture line 1 spells the recipe. It names the file (examples/app-showcase/objectstack.config.ts), the defineStack keys picklists and picklistExtensions, and definePicklist exported from @objectstack/spec. The extension value must be new, because a repeated value is refused at load with INVALID_METADATA. A same-package extension merges (pinned by engine-picklist.test.ts nested-plugin case; registerPicklistExtension has no own-package refusal). The run boots with --compile, because os dev otherwise serves an existing dist/objectstack.json. The fixture is reverted after the run and never committed. Reason: the triage re-check that the recipe is reproducible from text alone; the draft named neither the stack keys nor the file. (4) the console fixture line names objectui PR 11669 / merge c3623eb1 and the current pin, so whether the console carries it is checkable. (5) spec citations rewritten as gate-resolved anchors: PicklistSchema, PicklistExtensionSchema, PicklistServedFieldSchema, definePicklist, FieldSchema.picklist, and stack.zod.ts picklists / picklistExtensions. This follows the README anchor rule. The file census went 29 to 36 and the ledger 676/686 to 683/693, all resolved. The producer obligation 5925784898 is now located on objectui#10202, where the comment actually lives (the REST read on objectstack answered 404, on objectui 200). (6) history entry gains ref #21957 and lists these changes. Every source anchor named by the draft exists on main: protocol-picklist-served-roundtrip.test.ts, picklist.zod.ts with the three schemas, and the FieldSchema superRefine picklist/options refusal. The trap names stale-console-bundle and cache-staleness are in the RUNNER trap table, and surface mixed is in SURFACES. The hard limit holds: the steps go only through Setup Metadata Object and the Studio data page, never the OWD overview.",

Seat domain:devx#2 · session_01VF48aw8RPG6wzDnMgp6rtw · reviewed against GitHub and the fetched branch at 2026-10-06T07:51Z, not against the report.

PR shape.

Draft against main, body opening Fixes #21957, assignee os-justin.
Labels: size/s · skip-changeset.
One file, docs/qa/platform-checklist/areas/studio-authoring.json, +97/−0: the item studio-authoring.picklist-bound-select rev 1 is appended, and no existing item or index moves.
check-governed-merges.mjs --pr 21969: 0 of 1 path governed.
Checklist JSON only, so skip-changeset holds.

Triage's two re-checks (6011042888), each verified by this seat:

since: v17.7, not the draft's v17.6.
- objectui PR 11669 merged as c3623eb1 on 2026-10-06, after 17.6.0 shipped.
- In the objectui checkout, merge-base --is-ancestor c3623eb1 0abd4f9f8769 exits 1, so the console pin on objectstack main (.objectui-sha = 0abd4f9f8769) does NOT carry the feature. The reverse ancestry exits 0, so the pin predates it.
- The sibling item landed today uses v17.7 too.
- v17.7 holds only if the pin moves past c3623eb1 before the 17.7 cut, and the item's fixture says so. Otherwise a rev-2 since bump is owed.
The fixture recipe is reproducible from the text alone. The recipe's fixture line names:
- the file examples/app-showcase/objectstack.config.ts;
- the defineStack keys picklists and picklistExtensions;
- definePicklist from @objectstack/spec;
- the need for a new extension value;
- the --compile reload.
It stays uncommitted. A second fixture line requires a console carrying c3623eb1, through pnpm objectui:refresh, with the revision recorded.

One change from the draft forced by the gate: the draft's clause 3 used oracle mixed, which is not in ORACLES (scripts/check-platform-checklist.mjs:145: api, network, screenshot, dom, log, test, build). It is split into a dom clause and an api clause. The title, steps, negatives, traps, personas, priority and status are as drafted. The ruling's hard limit holds: no step goes through the OWD overview.

Gates. The dev ran 13 of 13, all exit 0 at eed17a88 (--ran reconciled). check:platform-checklist is OK at 275 items, with symbol anchors 683/693 resolved; the 10 unresolved are the existing residual.

Out-of-scope notes, in PR Acceptance notes, nothing filed: two picklist coverage waivers are now stale since #19519 landed. They are coverage.json's picklist waiver and examples/app-showcase/src/coverage.ts. Both are drift outside the filing classes, and their carrier is the next edit to those ledgers.

Landing: once every check on eed17a88 is green: pr_ready + automerge_enable, verify on main, and #21957 closes through Fixes.

Generated by Claude Code

Landed: PR #21969 → 230e4944b0, verified on origin/main by content at 2026-10-06T08:25Z. Seat domain:devx#2.

docs/qa/platform-checklist/areas/studio-authoring.json on main is blob-identical to the reviewed landing head eed17a88, and studio-authoring.picklist-bound-select (rev 1, since: v17.7) is present. The merge commit is an ancestor of origin/main.
The card was closed completed by the PR's Fixes #21957. pm:dispatched is removed in this act.
Carried, not owed here: since: v17.7 holds only if objectstack's .objectui-sha moves past objectui c3623eb1 (PR 11669) before the 17.7 cut. At this landing the pin is still 0abd4f9f. If 17.7 ships without it, the item owes a rev-2 since bump. The item's fixture line states the condition.
