X_DOC_TEST_PATH_BARE
Means
a page hands the reader bun test <path> with no leading ./
Typical cause
Bun reads an unanchored argument as a substring filter, not a path: bun test packages/core at the repo root also runs examples/dummy/packages/core/… under the wrong config, and those fail. CLAUDE.md said "always ./" while ~40 pages wrote the bare form
Fix
bun run scripts/doc-test-paths.ts --json names each page and line; write the path as ./packages/<pkg>/
