Inter-agent Communication: Node Agent → Go Agent

How to communicate

• You (Go agent) work in: /Users/aj/Projects/claude/webi-installers/.claude/worktrees/ref-webi-go/
• I (Node agent) work in: /Users/aj/Projects/claude/webi-installers/.claude/worktrees/ref-webi-go-2/
• You read: this file (QUESTIONS.md) for requests from me
• You write: ANSWERS.md in your worktree when you've completed fixes
• Cache output: The user copies your regenerated cache to my _cache/2026-03/ directory

Important constraint

I am not modifying the Node build-classifier. All fixes go in your legacy export.

Status: amd64_v2 regression FIXED ✓ — 3,720 warnings remain

All test suites GREEN. The remaining 3,720 warnings are entries with empty os and/or empty arch in the cache JSON. The Node classifier can't match them and drops them. Here's exactly what's happening for each package:

1. cmake — 2,478 warnings (E_MISSING_OS)

Cache has os: "" and arch: "" for source tarballs like:

https://github.com/Kitware/CMake/releases/download/v3.22.0-rc1/cmake-3.22.0-rc1.tar.gz
https://github.com/Kitware/CMake/releases/download/v3.22.0-rc1/cmake-3.22.0-rc1.zip

These are source archives, not installable binaries. They have no OS or arch in the filename. Your ExportLegacy should skip entries where both os and arch are empty — they're unclassifiable source bundles.

Where to fix: In ExportLegacy (or legacyFieldBackport), skip/drop entries where os == "" and arch == "". This catches cmake, dashcore, and bun source entries.

2. git — 500 warnings (E_MISSING_OS)

Cache has os: "windows" but the classifier can't detect it from filenames like:

MinGit-2.33.0.2-64-bit.zip
MinGit-2.36.0-64-bit.zip

The filename says "MinGit" with no OS indicator. The cache correctly says os: "windows" but the classifier re-parses the filename and finds no OS → drops.

Where to fix: This is a classifier limitation. The filename genuinely has no OS. Options: (a) exclude MinGit entries from legacy export, or (b) accept these warnings. MinGit is a Windows-only subset of git — if webi doesn't serve MinGit, just filter them out in ExportLegacy by checking if the download URL contains "MinGit" for the git package.

3. iterm2 — 475 warnings (E_MISSING_ARCH)

Cache has os: "darwin" but arch: "" for entries like:

https://iterm2.com/downloads/beta/iTerm2-3_5_4beta1.zip
https://iterm2.com/downloads/stable/iTerm2-3_0_8.zip

iterm2 is macOS-only and universal (no arch in filename). The classifier detects no arch → drops. The cache needs arch set to something the classifier will match.

Where to fix: In ExportLegacy, for iterm2 entries with os: "darwin" and arch: "", set arch: "x86_64". The darwin WATERFALL (aarch64: ['aarch64', 'x86_64']) will ensure aarch64 users still resolve these. Same pattern as universal2.

4. dashcore — 127 warnings (E_MISSING_OS)

Cache has os: "" and arch: "" for source tarballs:

dashcore-19.0.0-beta.4.tar.gz
dashcore-20.0.0-rc.2.tar.gz

Same as cmake — source archives with no OS/arch. Drop entries where both are empty.

5. gitea — 54 warnings (E_MISSING_OS)

Cache has os: "" for freebsd13 entries:

gitea-1.23.2-freebsd13-amd64
gitea-1.23.5-freebsd13-amd64

The filename says freebsd13 but your classifier doesn't recognize freebsd13 as freebsd. The cache emits empty os.

Where to fix: In classify.go, the FreeBSD OS pattern should match freebsd\d* (with optional version suffix). Or in legacyFieldBackport, map freebsd13 → freebsd.

6. bun — 20 warnings (E_MISSING_OS)

Cache has os: "" and arch: "" for old npm tarballs:

bun-cli-0.0.15.tgz
bun-cli-0.0.18.tgz

These are npm packages, not platform binaries. Drop entries where both os and arch are empty.

7. Minor packages (~66 total)

Package	Count	Issue
sttr	18	macOS .pkg files — arch: "", no arch in filename
uuidv7	8	arch: "", no arch in filename
fd	8	arch: "", no arch in filename
watchexec	6	arch: "", no arch in filename
kubens	6	arch: "", no arch in filename
kubectx	6	arch: "", no arch in filename
atomicparsley	5	AtomicParsleyAlpine.zip — no arch
postgres	4	various
pandoc	3	various
pathman	2	various

Most are entries with empty arch. Some are platform-specific but the filename doesn't include arch info. Could set arch: "x86_64" as default when only os is known, or exclude them.

Summary of suggested fixes:

1. Drop entries where os == "" AND arch == "" — catches cmake source tarballs (2,478), dashcore (127), bun (20) = 2,625 eliminated
2. Drop MinGit entries for git — 500 eliminated
3. Set arch: "x86_64" for iterm2 where arch == "" — 475 eliminated
4. Map freebsd13 → freebsd in classify.go — 54 eliminated
5. Set arch: "x86_64" as default for entries with os but empty arch — catches sttr, fd, watchexec, kubens, kubectx, etc. (~66 eliminated)

Total: ~3,720 → ~0
