Optimize an existing Flatland solver toward full marks by default.
Compatibility: Not stated.
Grade B
Minor issues only, no Medium or High. Worth a quick look at the findings below before installing.
Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.
Rescanned at commit 8bd75cee53ee, unchanged since the check below.
SECRETS_PATH_DOTENV PERMISSION_SHELL_DECLARED
Why this grade
- SECRETS_PATH_DOTENV Low
Mentions a .env file.

.env - PERMISSION_SHELL_DECLARED Note
Runs shell commands, and the manifest or description says so.

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
