build(types): type-check this package's tests, so the spec-derivation guards actually run (objectstack#4074)

[os-zhuang]

Follow-up to #3003. While correcting a comment there I measured something worth its own change: spec-derived-unions.test.ts — the file that exists to stop a spec-derived union from being re-forked into a hand-written copy — was not being compiled by anything.

Measured, not assumed

Its header claimed the satisfies checks in it "are the real enforcement". Reverting ActionParamFieldType from the spec's FieldType back to a hand-written subset:

	before this PR	after
tsc output	0 errors	TS1360 on the satisfies line

tsconfig.json excludes test files — correctly, since it is the package build (rootDir / composite / declaration), so tests would emit into dist — and no other tsc invocation read them. There is no vitest typecheck project either.

The sibling guards over ChartType, ReportType, ActionType and PageType were inert for the same reason, so the anti-regression mechanism left behind by #2944 / #2901 was not running in CI. Those forks were each already drifted once when they were found; nothing would have caught a second drift.

The fix

packages/types/tsconfig.test.json, chained from the package's type-check script — the shape this package already uses for tsconfig.examples.json: a separate, emit-free project.

Kept separate rather than deleting the exclude, for a reason that matters: the reexport guard scans sibling sources off disk, so it needs types: ["node"]. Folding that into tsconfig.json would let package source reference Node APIs and still compile, in a package that ships to browsers.

The 39 pre-existing errors it surfaced

p2-spec-exports.test.ts — 22. It imported eight …Schema names as types from ../index. #2561 decision (a) removed exactly those, and the sibling spec-ui-schema-reexports.test.ts asserts their absence — so this file contradicted its own guard for the whole interval. A type-only import of a nonexistent name erases at runtime, so the suite stayed green.

Its fixtures were also typed as parsed output while being parse input — these schemas .default() several fields, so { enabled: true } is valid input but the output type requires them. They now use z.input<>, the distinction spec draws itself with ActionInput. Same story for operator: 'eq': a legacy alias spec folds at parse time, valid as input and absent from the canonical output union. The value-type re-exports this file exists to pin are now asserted explicitly, instead of incidentally through fixture annotations.

app-creation-types.test.ts / system-fields.test.ts — 3. They imported the package by its own name. turbo's type-check task is dependsOn: ["^build"] (upstream only), so the package's own dist does not exist when it runs. They now use the relative import all 13 sibling tests use.

p1-spec-alignment.test.ts — 14, declared as debt rather than fixed. Excluded in tsconfig.test.json with a written reason, because these are not hygiene. Every one sits in a test named should accept <shape> whose entire purpose is asserting the type accepts that shape — and the type rejects it:

it('should accept sharing in ObjectUI format { visibility, enabled }', () => {
  const schema: ListViewSchema = { …, sharing: { visibility: 'team', enabled: true } };
  expect(schema.sharing?.visibility).toBe('team');   // can only pass: it asserts a JS
});                                                  // object literal kept the key just written

ListViewSchema.sharing is { type, lockedBy }. The legacy shape is real and is handled — foldSharing in core's normalize-list-view.ts folds visibility / enabled into the spec's ViewSharing.type — but only as untyped input (normalizeListViewSchema<T>(schema: T): T), so no type names it. That is the same "implementation wider than the type" shape as execute (objectstack#3856), navigation (#2944) and the param aliases (#3003).

Each of the 8 sites is a separate decision — widen the type so the claim becomes true, or drop the claim — and several touch the public surface. Rewriting them silently while landing the plumbing would bury the finding, so they are tracked on objectstack#4074.

Scope

Deliberately narrow: only packages/types, where the spec-derivation guards live. 28 other packages still exclude their tests; 5 (fields, cli, data-objectstack, plugin-charts, plugin-editor) already include them, so this establishes a pattern that is already load-bearing elsewhere rather than sweeping the repo.

This also corrects an overstatement in #3003, which said every package tsconfig excludes tests. It is 33 of 41.

Verification

• Discrimination check — the point of the PR: revert the derived alias, get TS1360. Zero errors before.
• pnpm type-check — 76/76 tasks.
• pnpm vitest run — 717 files / 8380 tests passed, 1 file / 24 skipped.
• packages/types: all three tsconfig projects clean; 16 files / 246 tests.
• eslint packages/types/src — 0 errors (249 pre-existing any warnings, none from this diff).
• node scripts/check-changeset-fixed.mjs — clean.

Changeset is patch: no public API changes, only build config and tests.
