The package implements production static server-function cache generation and retrieval. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Clean - **Confidence:** 98.0% - **Started:** 2026-08-22T23:17:11.378Z - **Finished:** 2026-08-22T23:18:29.333Z - **Download time:** 757 ms - **Static scan time:** 26 ms - **AI review time:** 77172 ms - **Total time:** 77955 ms ## Security analysis ### Published attack-surface review - **Summary:** No confirmed malicious attack surface. The package implements production static server-function cache generation and retrieval. - **Trigger:** Application middleware execution in production; cache writes additionally require TSS\_CLIENT\_OUTPUT\_DIR. - **Impact:** Expected build/output cache files and same-origin cache reads. - **Evidence paths:** package.json, src/staticFunctionMiddleware.ts, src/index.ts, dist/esm/staticFunctionMiddleware.js - **Review source:** ai\_review - **Reviewed:** 2026-08-22T23:18:29.333Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Writes and fetches serialized static cache entries. - **Rationale:** Direct inspection found a small middleware package whose filesystem and fetch behavior is limited to configured static-cache generation. No install-time execution, exfiltration, payload loading, or malicious control-surface mutation was found. - **Files touched:** TSS\_CLIENT\_OUTPUT\_DIR/\_\_tsr/staticServerFnCache/\.json ### Review decision - **Verdict:** Clean - **Confidence:** 98.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for:** Manifest has no preinstall/install/postinstall hook., Runtime file writes are gated by production mode and TSS\_CLIENT\_OUTPUT\_DIR., Fetch uses a generated same-origin relative cache path., No shell execution, dynamic code loading, credential harvesting, or external endpoint is present. - **Evidence against:** The package can write serialized server-function cache results to the configured output directory., It fetches cached results during production client execution. ## Public findings ### 1.
