Graded by PlugVetRubric v2

Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.

NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV OBFUSCATION_ENCODED_BLOB PERMISSION_SHELL_DECLARED

Why this grade

  • NETWORK_NO_FIXED_HOST Low

    Makes a network call whose host is not written as a fixed address.

    docs/ARCHITECTURE.md, line 714 **Server-side dashboard summary (2026-09):** the dashboard no longer fetches raw data and computes in WASM. `GET api/dashboard/summary?now=<client local DateTime>` (`Controllers/Da

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    docs/SCALING.md, line 2058 | `ConfigMap`/`Secret` | ECS task-definition environment/Secrets Manager | a `.env` file / Docker Compose `environment:` |

  • OBFUSCATION_ENCODED_BLOB Low

    Contains a long base64 shaped string in a file that should be readable.

    docs/ARCHITECTURE.md, line 1 # StudyLife - Architecture & Developer Documentation

  • PERMISSION_SHELL_DECLARED Note

    Runs shell commands, and the manifest or description says so.

    tools/coverage-report.py, line 36 result = subprocess.run(cmd, cwd=REPO_ROOT)

Any High, or two or more Medium findings, give D. One Medium gives C. Low findings or a security Note give B. Each code names a finding behind the letter.

Grades are a hygiene check of the source at the commit shown, on the date checked, not a security audit or a guarantee. The free directory grades are automated. Before release, a PlugVet engineer reviews every paid report and any grade we hold back, including all F grades, against the source code and the evidence we quote.

What was checked

Plain notes from the hygiene checks.

  • Permissions

    Note

    requests shell access. The manifest names this permission.

    PERMISSION_SHELL_DECLARED

    tools/coverage-report.py, line 36

  • Install and update

    Pass

    No install-time script found, and dependencies are pinned or absent.

  • Network

    Concern

    can reach a host that is not written as a fixed address.
