Symptom

`codedb_bundle ops=[{"tool":"codedb_outline"}]` (missing required `path`) returns top-level `isError: false` with the body containing `--- [0] codedb_outline ---\nerror: missing 'path' argument\n...`. Agents check the top-level `isError` and conclude the bundle ran fine.

Failing test

`tests.test.issue-bug11: codedb_bundle marks isError when all ops fail`

Fix

Track `ok_count` / `fail_count` per op in `handleBundle`. If `ok_count == 0 and fail_count > 0`, prepend `error: all N bundle op(s) failed\n` so the outer `is_error` check (`startsWith "error:"`) flips.
