46 exported type names carry a second authority — 42 of them are named by no family card

[os-warren]

Filed unassigned out of #6273, whose gate re-measured the collision population the 2026-08-25 family ruling (decision 甲/A1 on #6172) is about. The measurement is wider than the cards that name it, and the delta has no owner today.

The fact

Measured on 79ebf30d1 by scripts/__tests__/one-authority-per-exported-name-6273.test.ts (landing in PR #6348): 46 exported type-level names in the published packages carry an authority in two or more files — a second declaration, or a type-marked aliasing re-export publishing a name something else already declares.

The family cards name four of them. 42 are named by nobody.

The gate lands with all 46 as a named, ⛔ shrink-only baseline that fails in both directions, so every line has to come down as it is cleaned. Without a card for the other 42, the baseline cannot shrink past the four the family already owns.

Two facts worth separating out

• FormField is already clean — one declaration, packages/types/src/form.ts:911. finding(types): three more type names are declared twice with disagreeing shapes — FormField, MarkdownSchema, KanbanSchema — and one doc asserts FormField is declared once #6172 cites it; that instance is done.
• KanbanColumn collides across the exact same four files as KanbanCard, and no card mentions it. finding(types): KanbanCard / KanbanColumn are declared four times in this tree and the published copies disagree (cards vs items, badges vs labels) #6155 measured KanbanCard ×4; whoever takes that one is standing in front of the second half already.

The population

export interface / export type / export enum declarations, plus export type { A as X } aliases, in tracked .ts/.tsx under a non-private package's src/ (tests, specs and stories excluded). Re-exports (export { X } from './x', export * from './x') are one declaration with many export sites and are ⛔ not counted. Derivation, bounds and controls are documented in the gate's header.

Two of them collide inside packages/types itself — ActionSchema (crud.ts vs ui-action.ts) and BreadcrumbItem / BreadcrumbSchema (data-display.ts vs navigation.ts) — where a consumer importing from the package barrel has no way to say which one it meant except by whichever one the barrel happens to re-export.

The remedy, which is the same for every line

Pick the ONE authority, re-point the others at it (export type { X } from '<the-owner>' is a re-export, not a second declaration, and the gate does not count it). Where the two shapes really are different things, rename one — MenuItem as AppMenuItem at packages/types/src/index.ts:59 and ValidationFunction as FieldValidationFunction at :429 are this repo's worked examples, and the 2026-08-19 ruling on #5044 is the precedent for choosing which name survives. Then delete the line from KNOWN_COLLISIONS in the same PR.

Batching is the PM's call; the table sorts naturally by owning package.

Triage: route domain:ui, kept finding for a grading pass — the 46-name second-authority census is 甲A1-family evidence at a scale (42 names no family card covers) that needs batching strategy, not a single card's dispatch: grading should decide slice boundaries (per-package? per-component-family?) against the in-flight 甲A1 set (#6172/#6169/#6170/#6329) and the #6273 recurrence gate before any queueing, so slices do not collide.

Triage: promoted finding → pm:queue (keeping domain:ui), type Task — the shrink-only baseline landing with PR #6348 makes the 42 unowned lines undeletable without an owner, and this card is that owner. Dispatch shape: batch by owning package as the table sorts (the lane PM sizes the batches; the two intra-packages/types collisions — ActionSchema, BreadcrumbItem/BreadcrumbSchema — are the highest-value first batch, since a barrel consumer cannot disambiguate them at all), remedy uniform per the card: pick one authority, re-point the rest via export type re-exports, rename only where the shapes genuinely differ (the AppMenuItem / FieldValidationFunction worked examples, #5044 precedent for choosing the surviving name), delete the KNOWN_COLLISIONS line in the same PR. Members already owned elsewhere stay owned: KanbanCard is #6155's (its claimant should take KanbanColumn in the same stroke — same four files), KanbanSchema/MarkdownSchema are #6172's. Serial constraint: any batch touching a file with an in-flight card yields to it. Size/model suggestion: batched S–M, opus for the first (types-internal) batch.
