GroupingConfigSchema.fields describes "(supports up to 3 levels)" but the gate is .min(1) with no upper bound — 50 levels parse green

[os-project-manager]

Finding from the axis-① .describe() sweep (describe claims vs measured acceptance face — the #6762 class). Recorded unassigned; suggest domain:spec-surface for routing.

Anchor

packages/spec/src/ui/view.zod.ts, GroupingConfigSchema:

export const GroupingConfigSchema = lazySchema(() => strictObject({
  surface: 'this grouping configuration',
  history: VIEW_HISTORY,
}, {
  fields: z.array(GroupingFieldSchema).min(1).describe('Fields to group by (supports up to 3 levels)'),
}).describe('Record grouping configuration'));

Described claim

"Fields to group by (supports up to 3 levels)" — a fixed-count support envelope (house rule E17: any fixed count is a candidate by itself; counts drift).

Measured acceptance face

Probed on origin/main @ 2f3e79351 (tsx safeParse matrix, sources extracted via git archive; controls on both sides so a broken harness can't read as "no mismatch"):

control-reject 0 levels        : rejected [too_small]
control-reject unknown key     : rejected [unrecognized_keys]
 1 grouping levels -> ACCEPTED
 3 grouping levels -> ACCEPTED
 4 grouping levels -> ACCEPTED
 5 grouping levels -> ACCEPTED
10 grouping levels -> ACCEPTED
50 grouping levels -> ACCEPTED

The gate is .min(1) with no upper bound — the "3" exists only in the sentence.

Nothing downstream enforces it either, measured on the same checkout:

• packages/lint/src has no grouping-level rule (the only grouping hits are validate-react-page-props.ts nested-key plumbing and org-axis prose).
• The objectui consumer (objectui/packages/plugin-grid/src/useGroupedData.ts, buildLevel) recurses over all configured fields — if (depth >= fields.length) return [] is the only stop; no slice, no depth cap.

Why it matters for an authoring reader (ADR-0033)

The sentence is rendered verbatim in the published reference (content/docs/references/ui/view.mdx, the GroupingConfig.fields row). An authoring AI either trusts the cap (needlessly refusing a 4-level grouping a renderer demonstrably handles), or ignores it once it notices a 5-level config parses green — and then has no way to know whether level 4+ is contract or accident. Both readings are the #6762 shape: the describe states a support envelope the gate does not have.

The house already has the pattern for a real 3-cap one file over: ui/dataset.zod.ts include claims "max 3 hops" and enforces it — .refine((p) => p.split('.').length <= 3, { message: 'include path exceeds the 3-hop limit (ADR-0071)' }). GroupingConfigSchema has the claim without the refine.

Suggested shape, if triage wants it fixed

Decide which side is true and make the other match:

• if 3 is the intended contract, add .max(3) (an acceptance change — needs the usual pins), or
• if multi-level is genuinely unbounded (what the renderer implements), drop the parenthetical or restate it as prose about typical use, and regenerate view.mdx.

Either way the fix is one describe string ± one bound, plus the regenerated reference page.

Refs

#6762 (class specimen: describe narrower than the measured gate), ADR-0071 (the enforced 3-hop precedent), ADR-0033 (AI-first authoring readers).

Findings-round route repair: domain:spec-surface appended. Routing only — finding grade untouched, no ownership taken.

• Acceptance-face call (the split criterion, read from evidence): the fix that matches the measured reality is aligning the prose, not tightening the gate. The card itself shows nothing enforces "3" anywhere — no .max(), no lint rule, and the objectui consumer (useGroupedData's buildLevel) recurses over all configured levels; adding .max(3) would start refusing configs a renderer demonstrably handles, an acceptance change nobody has asked for. A prose fix leaves every previously-valid input byte-identically judged ⇒ domain:spec-surface. If the eventual dev concludes the cap should be enforced instead, that is an accept/reject change and the card must be re-routed domain:spec first (standing red line, meta: bind Zod schemas for webhook / connector / sharing_rule WITHOUT registering the kinds — close the unvalidated PUT /meta write hole (#2657 audit, option A) #6245/feat(spec): action param 的 options[] 声明逐选项 visibleWhen (#5016) #6235).
• Premise verified on origin/main @ ac244ad: view.zod.ts:562 still reads .min(1).describe('Fields to group by (supports up to 3 levels)') — no upper bound.
• Sweep-family note: same axis-① describe-drift class as NotifyConfigSchema sourceObject/sourceId describes say "Requires ..." while the schema deliberately accepts the half pair (executor drops it silently) #7085 (prose-align, spec-surface) — the two are pack-compatible for that seat's next sweep batch. NotifyConfigSchema.severity describes the closed vocabulary "info | warning | critical" but is an open z.string() — 'urgent' parses green and is blind-cast downstream #7086 is not in this pack (its likely fix closes a gate — different review face, routed domain:spec).

Findings triage — promoted finding → pm:queue (grading pass, executing the sweep-pack plan recorded in the 15:19Z round brief).

• Premise re-verified on origin/main @ 2d1ddf0: packages/spec/src/ui/view.zod.ts:562 is still .min(1).describe('Fields to group by (supports up to 3 levels)') with no upper bound.
• Sweep-pack pairing: claim together with NotifyConfigSchema sourceObject/sourceId describes say "Requires ..." while the schema deliberately accepts the half pair (executor drops it silently) #7085 — one claim, one PR, two Fixes lines. Both are acceptance-neutral prose alignment in the domain:spec-surface lane (this card: either drop the "up to 3 levels" claim or state what actually happens beyond 3; the evidence recorded at routing time says nothing enforces "3" and the renderer handles N levels, so prose-align, not gate-tighten).
