Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 12 low-signal pattern(s) reviewed. - **Verdict:** Clean - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Published - **Threat category:** None published - **Selected version:** 0.0.3021 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. The package has no install lifecycle hooks, and its entry points expose circuit-design functionality. The CLI wrapper sets a package asset path and loads the CLI; the inspected source does not show malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 87.0% - **Started:** 2026-10-29T20:09:43.465Z - **Finished:** 2026-10-29T20:10:20.770Z - **Download time:** 5344 ms - **Static scan time:** 60 ms - **AI review time:** 31900 ms - **Total time:** 37305 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** No attack was identified in the inspected package source. - **Trigger:** Package installation, library import, or invocation of the tsci/tscircuit CLI. - **Impact:** No unauthorized data collection, account action, destructive behavior, or concealed code execution was found in the inspected source. - **Review source:** ai\_review - **Reviewed:** 2026-10-29T20:10:20.770Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The package has no install lifecycle hooks; its library entry re-exports circuit tooling, and its CLI wrapper selects a bundled asset path before loading the CLI. - **Rationale:** The package has no install lifecycle hooks, and its entry points expose circuit-design functionality. The CLI wrapper sets a package asset path and loads the CLI; the inspected source does not show malicious behavior. ### Review decision - **Verdict:** Clean - **Confidence:** 87.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json declares no install lifecycle hooks; its scripts are build, test, and dependency maintenance scripts., The package entry exports its library bundle and browser bundle, and maps its CLI commands to cli.mjs., cli.mjs sets a path to the package’s bundled browser asset only when the environment variable is unset, then imports @tscircuit/cli., dist/index.js re-exports @tscircuit/core and @tscircuit/eval and exposes React and circuit-related utilities., The inspected eval dependency resolves service base URLs from explicit options, environment overrides, or defaults. - **Evidence against:** The CLI dependency source was unavailable for inspection, so its implementation could not be assessed., The browser and webworker bundles are large minified files; their broad content was not fully reviewed. ## Affected versions and remediation This report applies to tscircuit@0.0.3021. - Review the evidence and your use of tscircuit@0.0.3021 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.

Low: Url Strings - **Category:** Supply Chain - **Confidence:** 65.0% Package source contains URL literals. ### 6. Medium: Oversized Source File - **Category:** Artifact Inventory - **Confidence:** 70.0% - **Path:** dist/webworker.min.js - **Public source:** [View source]() Package contains source files above the normal full-analysis size ceiling. Public source snippet (untrusted): ```javascript path = dist/webworker.min.js kind = oversized_source_file sizeBytes = 18241615 magicHex = [redacted] ``` ### 7. Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 100.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ### 8. Low: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 87.0% - **Path:** package.json - **Public source:** [View source]() package.json declares no install lifecycle hooks; its scripts are build, test, and dependency maintenance scripts. Public source snippet (untrusted): ```json "scripts": { "build": "tsup-node && bun run copy-runframe-standalone && bun run copy-eval-webworker && cp types/static-assets.d.ts dist/static-assets.d.ts && bun run add-global-types-reference", "add-global-types-reference": "echo '/// ' | cat - dist/index.d.ts > dist/index.d.ts.tmp && mv dist/index.d.ts.tmp dist/index.d.ts", "test": "bun test", "upgrade-deps": ``` ### 9. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 87.0% - **Path:** package.json - **Public source:** [View source]() The package entry exports its library bundle and browser bundle, and maps its CLI commands to cli.mjs. Public source snippet (untrusted): ```json "exports": { ".": { "types": "./dist/index.d.ts", "default": "./dist/index.js" }, "./browser": "./dist/browser.min.js" }, "bin": { "tsci": "cli.mjs", "tscircuit": ``` ### 10. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 87.0% - **Path:** cli.mjs - **Public source:** [View source]() cli.mjs sets a path to the package’s bundled browser asset only when the environment variable is unset, then imports @tscircuit/cli. Public source snippet (untrusted): ```javascript // Expose the runframe + eval bundle shipped by this tscircuit version (the one // that provides the `tsci` binary) so `tsci dev` can use it when the project has // no local tscircuit installed. The CLI prefers a project-local tscircuit over // this, and an explicit RUNFRAME_STANDALONE_FILE_PATH over both. if (!process.env.TSCIRCUIT_GLOBAL_STANDALONE_FILE_PATH) { ``` ### 11. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 87.0% - **Path:** dist/index.js - **Public source:** [View source]() dist/index.js re-exports @tscircuit/core and @tscircuit/eval and exposes React and circuit-related utilities. Public source snippet (untrusted): ```javascript // index.ts export * from "@tscircuit/core"; import { jscad } from "@tscircuit/core"; export * from "@tscircuit/eval"; import { Fragment } from "react"; import { kicadFootprintStri ``` ### 12.
