# Public catalog data freshness

The Stratix Public catalog is refreshed continuously. This page documents how to interpret freshness signals on the site.

## What refreshes when

| Object                 | Refresh trigger                                                                              |
| ---------------------- | -------------------------------------------------------------------------------------------- |
| **Models**             | New models added when a provider releases or when LayerLens runs the first public evaluation |
| **Benchmarks**         | New benchmarks added on a roughly quarterly cadence                                          |
| **Public evaluations** | Continuous — new runs published as completed                                                 |
| **Leaderboard**        | Updates immediately when a new evaluation lands                                              |
| **Quarterly reports**  | Q1, Q2, Q3, Q4 — published shortly after the quarter close                                   |

## "Last updated" timestamps

Every model page, benchmark page, and evaluation page shows a "last updated" timestamp. The most useful field for deciding whether the score you're looking at is current.

## Methodology versioning

Benchmarks evolve. When LayerLens updates a benchmark's methodology (sample expansion, harness change, scoring tweak), the methodology version increments and old scores are versioned alongside the new one. The benchmark page surfaces the current methodology version and links to prior ones.

## Stale-warning conventions

* A score is **fresh** if it's within the last quarter
* A score is **dated** if it's >1 quarter and <1 year old
* A score is **stale** if it's >1 year old — the page shows a warning chip

Stale scores are still useful for context but should be re-run before being used to make a current decision.
