+# Dual-publish (GH Packages npm + JSR)
+
+Org epic: [KolektivComputer/.github#2](https://github.com/KolektivComputer/.github/issues/2)  
+Spine (Maven siblings): [gradle-conventions#1](https://github.com/KolektivComputer/gradle-conventions/pull/1) → `computer.kolektiv.publishing`
+
+## npm
+- Packages under **`@kolektiv/...` only** (already `@kolektiv/brand-core`, etc.) — do not invent a second JS scope
+- Dual: existing Yuri Capital npm **and** `https://npm.pkg.github.com` with `@kolektiv:registry=…`
+- Auth: `NODE_AUTH_TOKEN: ${{ secrets.GITHUB_TOKEN }}` with `permissions.packages: write`
+
+## JSR
+- Scope `@kolektiv` (owned); stub `packages/core/jsr.json` for `@kolektiv/brand-core`
+- Actions: OIDC only — `permissions.id-token: write` — **no org `JSR_TOKEN`**
+- Mey: link package on jsr.io for GitHub Actions trusted publishing
+- Not a substitute for npm publish
+
+## Workflow paste (token may lack `workflows` scope)
+
+```yaml
+permissions:
+  contents: read
+  packages: write
+  id-token: write  # JSR OIDC
+```
+
+```yaml
+- uses: actions/setup-node@v4
+  with:
+    registry-url: https://npm.pkg.github.com
+    scope: "@kolektiv"
+env:
+  NODE_AUTH_TOKEN: ${{ secrets.GITHUB_TOKEN }}
+```
+
+```yaml
+- run: npx jsr publish
+```
+
+Reference implementation: KolektivComputer/themes `publish.yml` + `.github/scripts/publish-*.sh`.
