Status from Go agent (ref-webi-go)

Current status: Phases 0–4 complete, integration testing clean

Node agent test results (as of 2026-03-11):

15/15 installer-resolve
49/49 live-compare (5 known — improvements over production)
190/196 broad sweep (6 expected: git/gpg/iterm2/mariadb have no binaries)
~7,400 PACKAGE FORMAT CHANGE warnings — informational only, don't block resolution

pgstore: PostgreSQL storage (pgx v5, double-buffer, CopyFrom bulk insert)
storage.Store interface: added ListPackages(ctx); both fsstore and pgstore implement
webid + webicached: -pg= flag to select pgstore over fsstore
golib middleware: request logging via middleware.WithMux
Legacy cache generation working for 101 packages (aliases/symlinks excluded)

Removed Windows arm→arm64 auto-promotion (caddy/fzf/goreleaser had explicit armv6 builds being wrongly promoted)
armel → armv6 (jq, caddy and others)
gnueabihf → armv6 explicit pattern (belt-and-suspenders for Rust triplets)
winx64 → windows/x86_64 (MariaDB)
ppc64el → ppc64le alias (Debian naming, jq)
armv6l → armv6 in normalizeGoArch (Go dist API used armv6l for older releases)
GPG classifier: hardcoded "amd64" → buildmeta.ArchAMD64 ("x86_64")
solaris/illumos → sunos in legacy export (Node.js only knows "sunos")
universal2: kept as-is in cache; Node agent handles via WATERFALL
go armv6→arm backport removed; Node classifier expects armv6 for armv6l filenames

Libc classification: Rust static musl → none, hard-musl packages keep musl
Windows gnu→none: MinGW self-contained
install.sh 8-space padding, PowerShell rendering
pg asset_filter: server-only assets (includes client)
comparecache field-level diffs: os/arch/libc/ext/channel with equivalence matching
Go dist: use API structured os/arch (illumos/solaris kept distinct in canonical storage)
sass: bare arm → armv7 in classifier (Dart Sass targets ARMv7)
LegacyBackport: moved to ExportLegacy (canonical values in pgstore, translations at export)
- ffmpeg: Windows .gz → exe (prod releases.js override)
.apk/.AppImage: added to classifier and correctly dropped from legacy export

Confirmed harmless. Go specific-OS-first order ([osStr, posix_2024, posix_2017, ANYOS, ""]) produces same results as production. No change needed.

Package	Field	Count	Go (correct)	Prod (wrong)	Why
iterm2	channel	11	stable	beta	Raw cache says stable (URL path `/stable/`). Prod misclassifies.
postgres	ext	2	.tar.gz	tar	normalize.js strips compression layer. File IS .tar.gz.
terraform	channel	14	alpha	stable	Version contains `-alpha-`. Prod regex misses it.

All other packages (98/101) have zero field-level disagreements. Not backporting these — Go is correct, production has bugs.

atomicparsley: AtomicParsleyAlpine.zip — needs per-package classifier config (hard musl). RESEARCHER confirmed: needs a releases.conf with asset pattern overrides, not generic detection.
Hugo .pkg: macOS v0.153+ only ships .pkg. Latent bug in both Go and production.
~3,200 remaining FORMAT CHANGE warnings (down from 6,149): all E_MISSING_OS/E_MISSING_ARCH from source tarballs (cmake, git), iterm2 no-OS filenames, dashcore, cmake obscure platforms. Cannot reduce further without per-package hardcodes or exclusion rules.
