Runtime middleware writes application static-cache data only when configured for production and fetches only a relative cache path. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Clean - **Confidence:** 98.0% - **Started:** 2026-08-14T12:34:07.250Z - **Finished:** 2026-08-14T12:34:34.525Z - **Download time:** 752 ms - **Static scan time:** 26 ms - **AI review time:** 26497 ms - **Total time:** 27275 ms ## Security analysis ### Published attack-surface review - **Summary:** No confirmed malicious attack surface. Runtime middleware writes application static-cache data only when configured for production and fetches only a relative cache path. - **Trigger:** Application invokes the exported middleware in production with TSS\_CLIENT\_OUTPUT\_DIR configured. - **Impact:** Writes serialized cache JSON below the configured client output directory; no external network target or credential collection is present. - **Evidence paths:** package.json, src/index.ts, src/staticFunctionMiddleware.ts, dist/esm/staticFunctionMiddleware.js - **Review source:** ai\_review - **Reviewed:** 2026-08-14T12:34:34.525Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Static server-function result caching. - **Rationale:** The package exports static middleware with scoped cache reads and writes, not install-time or covert behavior. Scanner network, environment, and hash signals correspond to this cache implementation. - **Files touched:** /\_\_tsr/staticServerFnCache/\.json ### Review decision - **Verdict:** Clean - **Confidence:** 98.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for:** No malicious behavior found after source and manifest inspection. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., The only filesystem write creates static cache JSON under TSS\_CLIENT\_OUTPUT\_DIR during production middleware execution., The only fetch uses a relative cache URL; no external host or exfiltration path is present., No shell/process execution, eval, dynamic loading, persistence, or agent-control-surface mutation was found. ## Public findings ### 1.
