## Security analysis

### Published attack-surface review

- **Summary:** No malicious attack surface is established. The optional store entrypoint creates and uses its own temporary JSON cache only after import.

- **Trigger:** Consumer imports caldryn/store and calls store methods.

- **Impact:** Limited, package-aligned local temporary-file writes; no confirmed exfiltration or destructive behavior.

- **Evidence paths:** package.json, index.mjs, store.mjs, README.md, index.d.ts, store.d.ts

- **Review source:** ai\_review

- **Reviewed:** 2026-08-05T07:45:09.211Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** Local JSON memoization in \<os-tmp\>/caldryn-store.

- **Rationale:** Source inspection shows a pure calendar utility plus an explicitly imported local temporary-file cache. No concrete malicious behavior or install-time execution exists.

- **Files touched:** store.mjs

### Review decision

- **Verdict:** Clean

- **Confidence:** 99.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence against:** package.json has no lifecycle scripts or dependencies., index.mjs only performs date and aggregation calculations., store.mjs uses node:fs only for an opt-in JSON cache under the OS temp directory., No network, subprocess, dynamic code execution, credential access, or persistence was found.
