Why this grade
- NETWORK_NO_FIXED_HOST Low
Makes a network call whose host is not written as a fixed address.
install.sh, line 29
curl -s -X POST "https://arbitrum-dapp-skill.goatcounter.com/api/v0/count" \ - NETWORK_UNNAMED_HOST Low
Calls a fixed host that the description does not name.
install.sh, line 29
curl -s -X POST "https://arbitrum-dapp-skill.goatcounter.com/api/v0/count" \ - SECRETS_PATH_DOTENV Low

references/deployment.md, line 16
# .env (never commit this file) - INSTALL_DOCUMENTED_INSTALLER Note

README.md, line 97
- [Foundry](https://getfoundry.sh/introduction/installation/) v1.0+: `curl -L https://foundry.paradigm.xyz | bash && foundryup`
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.
