feat(xpkg): V2 multi-arch xpm schema + arch normalization (0.0.42)#25
Merged
Conversation
Add architecture as a first-class, declarative xpm dimension (V2). A
version entry value may now be:
- per-arch resource map: { x86_64={url,sha256}, aarch64={...} }
- URL template + per-arch sha256: { url="...${arch}...", sha256={...}, arch_alias={...} }
- XLINGS_RES + checksums: { res=true, sha256={x86_64=,aarch64=} }
All legacy single-arch shapes parse unchanged. The loader keeps the raw,
arch-agnostic data; host arch is resolved at install time (xlings side).
- xpkg.cppm: normalize_arch()/arch_matches() (arm64<->aarch64, amd64<->x86_64);
ArchResource; PlatformResource gains archs/sha256_by_arch/arch_alias/is_res.
- xpkg-loader.cppm: parse the three new shapes; also fix a latent leak where
the platform-level 'exports' table was parsed as a bogus version entry.
- tests: 6 new cases (per-arch map, template, res, legacy-unchanged, arch norm).
17/17 loader+arch tests pass.

What
Make CPU architecture a first-class, declarative dimension of the xpm schema (V2). A version-entry value may now be:
{ x86_64 = {url,sha256}, aarch64 = {...} }{ url="...${arch}...", sha256={...}, arch_alias={...} }res = true+ per-arch sha256 — XLINGS_RES auto-URL, now with checksumsAll legacy single-arch shapes parse unchanged. The loader stores the raw, arch-agnostic data; the host arch is resolved at install time (xlings side).
