# NousResearch/hermes-agent · Memoization error in pytest-ancestor detection logic

## Open now

- #126766: \[Bug\] \`_has_pytest_ancestor\` memoizes a \`False\` derived from a transient \`psutil\` failure, permanently disarming the live-production-DB guard for the process
- PR #126813: fix(state): stop memoizing an indeterminate pytest-ancestry probe

A bug causes \`_has_pytest_ancestor\` to permanently cache a \`False\` result when a transient \`psutil\` failure occurs during the ancestry probe, incorrectly disabling a production-DB guard. The fixes stop memoizing indeterminate or erroring probe outcomes.
