# NousResearch/hermes-agent · MoA advisor failure handling and fallback logic

## Open now

- Nothing open on GitHub.

These items address fault tolerance in the MoA advisor fan-out process, specifically handling cases where reference model calls fail. The work covers containment of partial failures, short-circuiting when all references fail, and skipping the aggregator step in that scenario to avoid hangs.

## TL;DR

- 3 member(s): 0 open issue(s), 1 closed issue(s), 0 open PR(s), 1 merged PR(s), 1 PR(s) closed without merging.
- A fix was merged to main in PR #70281. Verify it addresses your case.
- **Recommended:** read PR #70281 (and any competing PRs below) before filing. Confirm the merged change covers your symptom.

## Maintainer resolution verdict

- Internal-tracker verdict over this cluster's issue members: `unresolved`. This is distinct from the fix status above. Weigh it yourself.

## How this cluster was grouped

- Link evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.
- Pairwise link density `0.67`: the share of member pairs that carry a link, counting a structural link in full and a relevance-only link at 0.36. `1.00` means every pair is linked.
