# Signals overview

> Every bad answer, missed retrieval, or user complaint — surfaced, clustered, and ready to fix.

**Signals** is the unified queue of things that might need improvement. Every 👎, every error, every verification block, every silent regression — all lands here.

Signals aren't tasks yet. They're **candidates**. You (or the system) decide which ones are real, which ones cluster together, and which ones get promoted into an Improvement.

## Where signals come from

  Six-plus channels feed Signals — user thumbs, verification, retrieval misses, and more.

## The signal lifecycle

1. **Detected** — a source (feedback, error, verification, etc.) fires.
2. **Enriched** — Nora adds context: the trace, the user, the intent, any prior similar signals.
3. **Clustered** — similar signals join together (see [Clusters](/reliable/signals/clusters)).
4. **Reviewed** — you confirm, mute, or edit the signal. Muting excludes false alarms.
5. **Promoted** — confirmed signals (or clusters) become **Improvements** in the improvement flow.
6. **Resolved** — the underlying issue is fixed and the signal closes.

Signals never delete themselves — they close as resolved or mute as false alarms. The audit trail matters.

## The queue view

Signals is a sortable, filterable list. Columns:

* **Severity** — high / medium / low. Auto-computed from source type, impact, and frequency.
* **Source** — which channel fired (feedback, verification, etc.).
* **Cluster** — cluster this signal belongs to, if any.
* **First seen** — when the pattern first appeared.
* **Occurrences** — how many times this pattern (or cluster) has fired.
* **Status** — new / reviewing / muted / promoted / resolved.

Common views: "New this week", "Unresolved high-severity", "Clusters with 5+ occurrences".

## Working through signals

Recommended cadence:

* **Daily** — glance at high-severity news signals. Confirm or mute.
* **Weekly** — review clusters. Promote to Improvements.
* **After a Flow change** — check regressions specifically (see [Regressions](/reliable/signals/regressions)).
