Nested copies inside the vault (e.g. `tools/cli/node_modules/...`, `tools/somerepo/.git/config`, a nested `.obsidian/`) were fully traversable via isAllowed/isAllowedForListing. Impact: a nested `.git/config` (remote URLs / embedded tokens) and nested `.obsidian` contents could be read, under the same prompt-injection threat model as GHSA-j99q-93c9-h869 (an attacker influences the path an agent reads).
