Findings for this version do not establish the status of other versions. AI assessment: manual review; recommendation: manual review. This assessment is supporting evidence; the published decision above determines the current policy. The inspected source shows model-property transfer as part of an exposed encoding operation, with no install-time trigger established in the reviewed excerpts. The complete clean-review citation requirement exceeds the 256-reference limit, so the result is manual review rather than a source-based warning or block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 78.0% - **Started:** 2026-10-25T22:22:12.095Z - **Finished:** 2026-10-25T22:24:45.676Z - **Download time:** 13086 ms - **Static scan time:** 14903 ms - **AI review time:** 125592 ms - **Total time:** 153581 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 confirmed attack was identified in the inspected excerpts. An exposed encoding method sends model properties to DeepSeek when called. - **Trigger:** A caller invokes OneClickEncoding.start(). - **Impact:** Model properties are disclosed to the configured AI service for encoding; the reviewed source does not establish that this happens without the method being called. - **Review source:** ai\_review - **Reviewed:** 2026-10-25T22:24:45.676Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The method gathers BIM component properties and submits them in batches to the DeepSeek chat endpoint. - **Rationale:** The inspected source shows model-property transfer as part of an exposed encoding operation, with no install-time trigger established in the reviewed excerpts. The complete clean-review citation requirement exceeds the 256-reference limit, so the result is manual review rather than a source-based warning or block. - **Files touched:** dist/chunks/EngineKernel-B\_ffOihq.js - **Network endpoints:** https://api.deepseek.com ### Review decision - **Verdict:** Manual Review - **Confidence:** 78.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The package manifest points consumers to its SDK entrypoints and lists development and build scripts., The SDK constructs a OneClickEncoding instance and exposes its start method., Calling start gathers model component properties and passes them in batches to startChat., The chat method sends those batches to the configured DeepSeek chat endpoint using the deepseek-chat model. - **Evidence against:** The reviewed transfer is inside an exposed encoding method; the inspected code does not show it running during package installation., The required clean-review citation set exceeds the 256-citation limit, preventing a clean verdict under this review’s coverage rules. ## Affected versions and remediation This report applies to iflow-engine-base@4.1.3. - Review the evidence and your use of iflow-engine-base@4.1.3 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.
