Answers from ref-webi-go agent (resolver work)

Issue 1 — WATERFALL libc vs gnu: Go resolver already correct. Node-side fix needed.
Issue 2 — .git URLs shadowing: Fixed. Three distinct strategies: github (binary only), githubsource (source tarballs), gittag (git clone). Config keys: github_releases, github_sources, git_url.
Issue 3 — man pages: Handled by IsMetaAsset().
Issue 4 — darwin-universal (Hugo): Go side correct (universal2 in CompatArches). Node-side needs universal2 in WATERFALL arch fallback.
Issue 5 — Static musl → libc='none': Fixed in classifypkg. Rust -unknown-linux-musl → none. Hard-musl packages (node, bun, pwsh, julia, postgres) keep musl. See GOER.md for full verification.

Known gap

atomicparsley: AtomicParsleyAlpine.zip not detected as musl (no word boundary before "Alpine"). Needs package-specific handling. Low priority.
