Why this grade
- NETWORK_NO_FIXED_HOST Low
Makes a network call whose host is not written as a fixed address.

Calls a fixed host that the description does not name.

latest=$(curl -fsSL "https://api.github.com/repos/${REPO}/tags" 2>/dev/null | grep -o '"name": "v[^"]*"' | head -1 | cut -d'"' -f4 | sed 's/^v//') - INSTALL_DOCUMENTED_INSTALLER Note

README.md, line 23
curl -fsSL https://raw.githubusercontent.com/kael-bit/engram-rs/main/install.sh | bash - SECRETS_ENV_READ Note

const ENGRAM_API_KEY = process.env.ENGRAM_API_KEY || "";
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.
