Surfaced while implementing objectui#6132 (PR #6345). Not fixed there: that card ruled a docs question, and this is a code-side contract question whose fix lands in packages/.
What was measured
objectui#6132's ruling redirects three menu reference pages at MenuItem.onClick, on the grounds that it is a real declared slot. It is — I verified it in three places before doing the redirect:
- source
packages/types/src/overlay.ts:346 — onClick?: () => void; - built
packages/types/dist/overlay.d.ts:334 — the exact line objectui#6132 cited - Zod mirror
packages/types/src/zod/overlay.zod.ts:136 — onClick: z.function().optional().describe('Click handler')
But no renderer reads it. The renderers read a different, undeclared key on the same item:
// packages/components/src/renderers/overlay/dropdown-menu.tsx:67<DropdownMenuItemkey={i}disabled={item.disabled}inset={item.inset}onSelect={item.onSelect}>
// packages/components/src/renderers/overlay/context-menu.tsx:65
<ContextMenuItemkey={i}disabled={item.disabled}inset={item.inset}onSelect={item.onSelect}>packages/components/src/renderers/overlay/menubar.tsx wires no item handler at all — neither spelling.
Neither onSelect nor inset is declared on MenuItem. The helper is typed renderMenuItems(items: any[]), which is why the mismatch type-checks.
Confirming the negative:
$ grep -rn "onClick" packages/components/src/renderers/overlay/*.tsx(no matches)
Why it matters
Declared and enforced disagree in both directions on the same object:
- an author following the shipped type writes
onClick — it validates, it publishes, and it never fires; - an author who gets a working menu wrote
onSelect — which no type declares, so nothing protects it from being renamed away.
This is the failure mode objectui#6132's own four-axis analysis called the most expensive one ("能通过校验、能发布、然后静默什么都不做"), except here it survives because the prop is declared, so it reads as correct.
Note this is a thirdMenuItem-shaped defect in the same family as objectui#6326 and objectui#6278 (both about an item's icon), and unlike those it is about the handler rather than the glyph.
The decision this needs
Which spelling is the contract?
I have no recommendation strong enough to skip triage — B matches observed runtime behaviour, A matches the published declaration, and the choice depends on whether any authored onSelect exists in the wild. Worth measuring before ruling.
⚠️ Whichever way this goes, PR #6345's three doc pages (overlay/context-menu.mdx, overlay/dropdown-menu.mdx, overlay/menubar.mdx) name onClick and would need the same correction under option B.
