## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 13 finding(s) warrant review before installing.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Matched warn-list
- **Public report status:** Published
- **Threat category:** Destructive Action
- **Selected version:** 4.6.1
- **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: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy.

Source inspection confirmed that the scanner’s runtime-install signal is part of the user-invoked initializer, not an install hook. The initializer also removes a project-name-derived Docker volume in \`--yes\` mode, leaving a conditional data-loss risk that warrants a warning.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 88.0%
- **Started:** 2026-10-21T04:04:49.191Z

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:** The \`init --yes\` setup flow can remove a Docker volume whose name is derived from the current directory. If that volume already contains data, setup can destroy it without an interactive confirmation.

- **Trigger:** A user runs the published \`kempo init --yes\` command in a directory whose derived volume name already exists.

- **Impact:** Existing PostgreSQL data in that volume may be lost.

- **Evidence paths:** bin/cli.js

- **Review source:** ai\_review

- **Reviewed:** 2026-10-21T04:06:01.120Z

### AI review details

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

- **Mechanism:** The CLI stops and removes a matching container, then calls Docker to remove the derived volume before Compose starts a new container.

- **Rationale:** Source inspection confirmed that the scanner’s runtime-install signal is part of the user-invoked initializer, not an install hook. The initializer also removes a project-name-derived Docker volume in \`--yes\` mode, leaving a conditional data-loss risk that warrants a warning.

- **Files touched:** bin/cli.js

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 88.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** The published CLI runs only for the explicit \`init\` command and accepts \`--yes\` for default setup., With \`--yes\`, the database name and container name come from the current directory name., During new-container setup, the CLI stops and removes a same-named container and removes its \`${dbName}\_postgres\_data\` Docker volume before starting Compose; an existing volume can contain data.

- **Evidence against:** The manifest defines no install lifecycle hook; the package-manager install occurs only after the user invokes the CLI setup flow., Interactive reinitialization warns that project files will be deleted and requires confirmation.
