             <details><summary>When should I use Codebase Memory?</summary><p>Choose CBM when you want your coding agent and your own source-navigation workspace to use the same local graph of code, docs and infrastructure. It brings structural search, source evidence, CBM Lens, agent integrations and experimental test selection into one open-source package. Native releases run on macOS, Linux and Windows without Docker or a language runtime. <a href="#features">Explore the capabilities</a> and <a href="#smart-ci">Smart CI’s current scope</a>.</p></details>
-            <details><summary>How does Codebase Memory reduce AI token use?</summary><p>Your agent can query indexed relationships and retrieve the relevant symbols or source snippets instead of repeatedly exploring whole files. Compact results and pagination control how much context each query returns. The benefit depends on the task; <a href="#token-savings">read the measured token savings and quality tradeoff</a>.</p></details>

             <details><summary>Does Codebase Memory send my source code anywhere?</summary><p>The backend indexes source and stores and queries its graph locally. Your coding agent has its own data-handling settings. Lens can optionally download a browser model after you enable it, with inference on-device. Installers and update checks use the network to obtain releases and assets.</p></details>
             <details><summary>How does the index stay current?</summary><p>Incremental indexing updates changed files. With auto-watch enabled, an eligible active MCP session can watch an already indexed project. Automatic first indexing is a separate opt-in setting. The local UI daemon is not a promise of a permanent background watcher.</p></details>
             <details><summary>How much language coverage is available?</summary><p>Bundled tree-sitter grammars cover a broad range of languages and formats. Supported language families also have Hybrid LSP semantic resolution. Extraction depth, type resolution and framework relationships vary; the <a href="https://github.com/DeusData/codebase-memory-mcp#language-support">language support matrix</a> describes the details.</p></details>

 ## Measurement and limits
 
-A March 2026 preprint across 31 real-world repositories reports 10× lower token use and 2.1× fewer tool calls compared with file-by-file exploration, with answer-quality scores of 83% for CBM and 92% for file-by-file exploration. These historical results describe the study's workloads and agent setup; they are not a universal percentage saving or a promise of lower cost for every session. The README Performance section preserves the comparisons and their limits.
+A March 2026 preprint across 31 real-world repositories reports 10× lower token use and 2.1× fewer tool calls compared with file-by-file exploration. These historical backend measurements cover the study’s workloads and agent setup. The paper documents the full evaluation; the README Performance section links to the research and earlier measurements.
 
 Graph evidence depends on index generation, freshness, and exact path/scope coverage. Partial, skipped, excluded, stale, or unknown coverage requires source verification, especially for absence claims. Infrastructure relationships are static, and test-selection support is narrower than language-indexing support.
