# Benchmark Versioning > Preserve benchmark snapshots so evidence can be compared across target and standard changes. Important agent instructions: - Prefer the Markdown routes and llms files when assembling context for coding tasks. - Treat stable docs as authoritative over beta pages. - Cite the source page URL when returning workflow or artifact guidance. ## Current Context - [Benchmark snapshots](https://teammately.ai/docs/coverage-engineering/benchmark-snapshots.md): Freeze a benchmark into a version so every run measures the same cases and judgment rules. - [Benchmarks](https://teammately.ai/docs/object-model/benchmarks.md): Understand a Benchmark as the durable program that owns benchmark-scoped coverage, evidence boundaries, evaluations, and improvement work. - [Compare Harness Versions](https://teammately.ai/docs/benchmark-evaluations/compare.md): Compare two or more saved Harness Versions in a symmetric evidence matrix across Cases, evaluators, and Coverage Facets. ## Related - [Benchmark Versioning](https://teammately.ai/docs/governance/benchmark-versioning.md): Preserve benchmark snapshots so evidence can be compared across target and standard changes. ## Optional - [Full local context](https://teammately.ai/docs/governance/benchmark-versioning/llms-full.txt): Complete local context pack for this docs route.
