Validator finding #12 from the publish-debate-vortex hyperultradebate flagged that internal-only skill and command assets could leak into the npm payload once the dot asset roots are included.
Bun 1.3.x ignores a root .npmignore for directories listed in package.json#files, so the exclusion rules live in nested .npmignore files co-located with each published command and skill directory.
RED before nested ignores: bun test script/package-layout-exclusion.test.ts failed with expect(received).toEqual(expected), receiving .opencode/skills/__internal-fake-do-not-ship-test-artifact/SKILL.md, .agents/skills/__internal-fake-do-not-ship-test-artifact/SKILL.md, .opencode/command/__internal-fake-do-not-ship-test-artifact.md, and .agents/command/__internal-fake-do-not-ship-test-artifact.md instead of [].
GREEN after nested ignores: bun test script/package-layout-exclusion.test.ts reported 2 pass, 0 fail, 5 expect() calls.
This is the exclusion companion to script/package-layout.test.ts, the inclusion test arriving through the dev merge.
