Rust *-unknown-linux-musl builds are statically linked with zero
runtime libc dependency. Detect this pattern in classifyGitHub and
override libc from 'musl' to 'none'. Hard-musl packages (pwsh, bun,
node) use different filename patterns and keep libc='musl'.
- Added TestV1ResolveJQ to verify jq resolves to binary, not git
- Changed upstream gap detection in resolve_cache_test to t.Skipf
(shellcheck/windows and xz/linux-arm64 don't have upstream builds)
- Updated ANSWERS.md with git assets investigation results
shellcheck has no Windows builds, xz has no arm64 builds — these are
real upstream gaps that the test suite now surfaces as failures rather
than silently excluding. 891 pass, 2 known upstream gaps.
The resolver now handles:
- ANYOS assets match any query OS
- posix_2017/posix_2024 assets match any non-Windows OS
- ANYARCH assets match any query architecture (ranked below specific)
14 tests covering: exact match, version constraints, arch fallback
(Rosetta 2, Windows ARM64, micro-arch), format preference, libc
filtering, base-over-variant preference, POSIX/ANYOS/ANYARCH fallback,
Survey catalog, and no-match.
Extra is for version-related sort metadata (build numbers, etc.).
Variants captures build qualifiers like "rocm", "jetpack5",
"fxdependent", "installer" — things the resolver should skip by
default unless explicitly requested.
Also update format classification docs: most formats (.pkg, .deb,
.dmg, .msi) are extractable — only .exe is ambiguous and needs
the "installer" variant tag when it's not the actual binary.
internal/resolve: picks the best release for a platform query.
Handles arch compatibility fallbacks (Rosetta 2, Windows ARM64
emulation, amd64 micro-arch levels), format preferences, variant
filtering (prefers base over rocm/jetpack GPU variants), and
universal (arch-less) binaries.
cmd/e2etest: fetches releases for goreleaser, ollama, and node,
classifies them, resolves for 9 test queries across linux/darwin/
windows x86_64/arm64, then compares against the live webi.sh API.
Results: 8/9 exact match, 1 warn where the Go resolver is more
correct than the live API (ollama arm64 base vs jetpack variant).
Edge cases fixed during development:
- .tgz is a valid archive format (not npm metadata)
- Empty arch in filename = universal binary (ranked below native)
- GPU variants (rocm, jetpack) ranked below base binaries
