## Security analysis

### Published attack-surface review

- **Summary:** No confirmed malicious attack surface is established. The optional server entry performs package-aligned memoization through an imported dependency.

- **Trigger:** Consumer explicitly imports svelte-mapped-metrics/server and calls streaksCached.

- **Impact:** No package-owned exfiltration, remote execution, persistence, or destructive behavior found.

- **Evidence paths:** package.json, dist/index.mjs, dist/internal/streakmath.mjs, dist/server.mjs, types/index.d.ts, types/server.d.ts, README.md

- **Review source:** ai\_review

- **Reviewed:** 2026-08-06T14:10:06.241Z

### AI review details

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

- **Mechanism:** Local streak calculation with optional dependency-provided cache.

- **Rationale:** Direct inspection found a small analytics library with no install hooks or concrete attack behavior. The server-only cache is explicitly user-invoked and no harmful file or network action is implemented by this package.

### Review decision

- **Verdict:** Clean

- **Confidence:** 94.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence against:** package.json has no lifecycle scripts or bin entrypoint., dist/index.mjs only computes streak metrics from supplied entries., dist/internal/streakmath.mjs contains local date/run-length logic only., dist/server.mjs is an explicitly imported cache wrapper; it hashes inputs and delegates storage to its dependency., No network, shell, eval, environment harvesting, or destructive operations appear in package files.
