+# GitWorkshop upstream
+
+This image packages the GitWorkshop NIP-34 web client from:
+
+- Source: https://github.com/DanConwayDev/gitworkshop
+- Pinned commit: `dc36db64f6a2cca29d109829eabaf0a49d4bf4da`
+- Upstream project: https://gitworkshop.dev/
+- App icon: `public/icons/icon.svg` from the same pinned revision (the artwork
+  is only inset onto Archipelago's standard icon safe area).
+
+The small build patch only makes the upstream Vite/React application work
+below Archipelago's `/app/archipelago-source/` mount, injects the existing
+consent-gated Archipelago NIP-07 provider, disables the development-only
+`localhost:4869` cache-relay probe, and removes two unreachable lookup relays
+from the defaults. It does not replace GitWorkshop's NIP-34, GRASP, repository
+browser, issue, pull-request, or review interfaces.
+
+The pinned revision and current upstream `main` do not contain a license file,
+the package metadata declares no license, and GitHub reports no detected
+license. This development image is for local evaluation only. Do not publish
+it to the production app registry until upstream adds an explicit license (the
+preferred auditable resolution) or its maintainer provides a written grant
+covering compilation, modification, and redistribution.
