    // [#12181] `@objectstack/metadata-core` and `@objectstack/metadata-protocol`
    // are imported by `src/meta-delete-item-carriers.test.ts` (the real-door
    // reproduction), i.e. by the TEST program `tsconfig.test.json`, which
    // extends this file. Without these rules tsc resolves those specifiers
    // through each dependency's `exports` map — `dist/index.d.ts`, A BUILD
    // ARTIFACT — so the verdict would be about the last `pnpm build` rather
    // than about the producer's source in the checkout.
    // `check:type-source-resolution` refuses exactly that, and its header
    // states why the dangerous case is a typecheck that PASSES.
    //
    // ONE rule per package, not two: both publish a single entry point (their
    // `exports` maps carry only `"."` besides, for metadata-core, a `./testing`
    // subpath nothing here imports), and a rule pointing at files that are not
    // on disk is worse than absent — tsc falls back to node resolution, i.e. to
    // `dist`, silently. ⛔ Never spell a key with a star not preceded by a
    // slash (`@objectstack/metadata-core*`): it matches the bare name AND every
    // subpath, folds them onto one target, and type-checks green against the
    // wrong module.
    //
    // `rootDir` stays `./src`: this BUILD program excludes `**/*.test.ts`, so
    // no file in it imports either specifier and neither producer's source is
    // pulled in here. The test program that does pull them in already sets
    // `rootDir` to the workspace root.
    // [#12104] Same rule, same reason, for the three producers
    // `src/analytics-automation-json-erasure.test.ts` DRIVES to measure what
    // the five `return res.json()` methods really resolve to. That suite's
    // claim is "the annotation matches what the producer sends", so its verdict
    // must be about the producer's SOURCE; through `exports` it would be about
    // the last `pnpm build` of three other packages. Each publishes a single
    // `"."` entry point, so one bare-name rule each — no star, per the
    // paragraph above.
