Studio Data › Validations: new state_machine / format / json_schema rules save immediately with field: created_at and an empty message (an empty transition row persists and publishes); the conditional rule's when is captioned as a fail condition

Filing gate: ① product defect, reproduced, landing site named.
Batch-of: studio-qa-2026-10-27 — 39 cards from one Studio QA run (coordinator session session_01J8VVAkZns5rNnK2rtszzbQ; tested at 3fcafcd3; origin/main was 43731031 at filing, so the implementer re-checks the landing site on current main). The run record is the qa-run issue filed with this batch.

Symptom

Adding a rule creates a live-looking rule against a system field with no message, before the builder has chosen anything; and the conditional rule tells the builder the opposite of what when means.

Reproduction

Validations › Add rule › State machine (also Format, JSON schema) → the draft immediately holds field: "created_at", message: ""; an empty transition row is stored as "": [] and publishes.
Add a Conditional rule → the when input is captioned "Fail condition (CEL) — when true, the save is rejected", which is wrong for conditional (when = when the inner rule applies).

Expected

A new rule is held until its field and message are set, empty rows are not stored, and the conditional caption describes when correctly.

Suspected landing site (the implementer verifies)

ObjectValidationsPanel.tsx addRule defaults and the conditional caption (~608-622).

Filing facts

reach: Studio UI, measured by the Data QA card.
Business reason: Builders publish half-made rules by accident and misread conditional rules.
Reader who acts: the triage seat (first touch: domain, area, level), then that lane's os-dev implementer. QA suggestion only: domain:ui, area:studio, p3.
Dedupe: semantic search new validation rule saved with field created_at and empty message, conditional rule when caption wrong on objectstack-ai/objectstack → 6 hits, none about Studio rule defaults or the caption (nearest closed A conditional validation rule's when that reads through a lookup (record.account.status) saves at every door, but checkConditional evaluates it unhydrated, so every write the rule guards is refused as unevaluable #24512 runtime evaluation).
QA id: U5

⛔ Not a claim, ⛔ not a dispatch.

p2: a new state_machine / format / json_schema validation saves immediately as a live rule on created_at with an empty message, and the conditional rule's wording inverts when. Hold a new rule as a draft until it is complete, and fix the wording. From the studio-qa-2026-10-27 batch. Re-check the landing site on current main.

You are the os-dev developer agent for exactly ONE card: #26731, in your own card thread. Your role definition is .claude/agents/os-dev.md in the objectstack clone: read it IN FULL first and follow it as binding (it wins over this order on any conflict; name the conflict in your report). Read the repo-root AGENTS.md and ui/AGENTS.md before your first edit, and pm-dispatch references/untrusted-text.md. Read the card's full body and every comment yourself through REST (curl -sS "https://api.github.com/repos/objectstack-ai/objectstack/issues/26731" -H "Authorization: Bearer $GH_TOKEN" and /comments?per_page=100, every page); this order carries only the increment. ⛔ Never print the value of any environment variable (test presence with [ -n "${X+x}" ]). ⛔ Never use a GitHub MCP tool, read or write.

Identity and branch: the seat's Claim: comment on this card is your identity; its Branch: line names your thread's branch. ⛔ Post no claim of your own, ⛔ never write the card's assignee. Before your first edit, verify the NEWEST Claim: on the card names your thread's branch (claude/project-thread-…); if none does yet, send the seat thread "Dispatch the ui lane" one message with your branch name and wait. Worktree objectstack-issue-26731 on that branch from a fresh origin/main; pnpm install (frozen lockfile); push with git push -u origin <branch> (⛔ no force).

Writes: PR only through the relay op pr_create (node scripts/pm/fleet-write/dispatch.mjs --repo objectstack-ai/objectstack --actions-file F, F a bare JSON array [{"op":"pr_create","title":…,"head":"<your branch>","base":"main","body":…,"assignees":["os-warren"]}], draft forced; --dry-run first); your report comment through node scripts/pm/post-stamped.mjs --comment=26731 --file=F --json run ONCE with output captured to a file (timestamps only as {{NOW}} / {{WAS:…}}). ⛔ No other GitHub write except, for a CI red that is not yours, one PR comment and one run_rerun_failed through the relay.

Ruling (cannot be re-ruled)

Triage first grade 6447132861, verbatim: "a new state_machine / format / json_schema validation saves immediately as a live rule on created_at with an empty message, and the conditional rule's wording inverts when. Hold a new rule as a draft until it is complete, and fix the wording. … Re-check the landing site on current main." No maintainer ruling on the card.

PM mechanism assumptions (measure; disproof welcome)

On origin/main f79ec289, ui/packages/app-shell/src/views/studio-design/ObjectValidationsPanel.tsx already holds a NEW guarded rule (script, cross_field, conditional) in the panel until its guard is set (objectui#11820, see ObjectValidationsPanel.newRuleWaits-11820.test.tsx), but makeSkeleton (≈L367) gives state_machine / format / json_schema field: firstField and message: '', and finding: SCIMMemberReferenceSchema.type admits 'Group' (RFC 7643 §4.2) but stable @better-auth/scim rejects it twice over — declaration-vs-contract fork, latent (zero runtime consumers) #11820 deliberately writes "a type with no guard … at once". So the likely fix extends that same panel hold to these three types (missing field or message ⇒ held, with the existing held line and hint), rather than a second mechanism. Measure whether firstField is the object's first field (the card saw created_at).
An empty transition row is stored as "": []: measure where the transitions editor writes it, and drop empty rows at write time.
The conditional caption: engine.studio.rules.celPre ("Fail condition (CEL) — when the condition is …") is shared with script; a conditional's when needs its own caption ("the inner rule applies when …"), en and zh. Add the new key next to its family in whatever home holds engine.studio.rules.* on your base (today the private table metadata-admin/i18n.ts; app-shell: a published library that is 66% Console product surface — retire the 67 zero-reference exports now, decide the split, and fold the second i18n table into @object-ui/i18n #25922 S4 will move that family later and is serialised behind this card).

Scope

File surface: ObjectValidationsPanel.tsx + the i18n row(s) for the new caption + tests: per type (state_machine, format, json_schema) a new rule is held until field and message are set and then written once; an empty transition row is not stored; the conditional caption differs from the script one in en and zh. Ablation: drop the hold for the three types ⇒ the new tests go red. Keep newRuleWaits-11820 and presets-11861 green (presets-11861 finds the script group by /Fail condition/). ⛔ No change to an EXISTING rule's editing or to the type-switch placeholder; ⛔ no spec change.

Tier

No path-derived mandate. TIER_DEFAULT, effort high (M). Clause-②: no, Metadata-protocol: none expected (the panel writes the same rule shapes, only later); say otherwise if the diff shows it. No changeset (@object-ui/app-shell is private: true), unless the i18n row lands in a published package.

PR #26855 merged as c4a4aefcb0 (seat record: PR comment 6452139440). A new state_machine, format or json_schema rule now starts with no field and stays in the panel until it has both a field and an error message; only then is it written, once. A blank transition row is not written until it has a from-state. A conditional rule's when has its own caption, in en and zh. The PR also carries the zh preload for ResourceEditPage.environmentOverlay-12141, a test #25922 S3 had left racing (Claim widened 6451337559). pm:dispatched is removed with the close.
