-# Forgejo Registry Secrets Configuration
-
-## One-Time Setup (Org Level)
-
-All repos in the `rock` org share the same Forgejo registry credentials.
-
-### Configure at Organization Level
-
-1. Navigate to: https://forgejo.riotpiao.com/rock
-2. Click Settings (gear icon)
-3. Go to: Actions → Secrets
-4. Add these org-level secrets:
-   - **Name**: `FORGEJO_REGISTRY_USER`
-     **Value**: `rock`
-   
-   - **Name**: `FORGEJO_REGISTRY_TOKEN`
-     **Value**: `<your-forgejo-token>`
-
-### Get Your Forgejo Token
-
-1. Go to: https://forgejo.riotpiao.com/user/settings/applications
-2. Click "Generate New Token"
-3. Set scopes: `api`, `read:registry`, `write:registry`
-4. Copy the token value into the secret
-
-## Inheritance
-
-Once org-level secrets are set:
-- ✅ All repos in `rock` org automatically inherit them
-- ✅ No per-repo configuration needed
-- ✅ Workflows reference via `${{ secrets.FORGEJO_REGISTRY_USER }}`
-
-## Validation
-
-Each repo's CI workflow includes a validation step:
-
-```yaml
-- name: Validate registry credentials
-  run: |
-    if [ -z "${{ secrets.FORGEJO_REGISTRY_USER }}" ] || [ -z "${{ secrets.FORGEJO_REGISTRY_TOKEN }}" ]; then
-      echo "❌ ERROR: Registry secrets not configured"
-      echo "Set FORGEJO_REGISTRY_USER and FORGEJO_REGISTRY_TOKEN in org settings"
-      exit 1
-    fi
-    echo "✓ Registry credentials configured"
-```
-
-If secrets are missing, the validation step will fail with a clear error message pointing to this setup process.
-
-## Affected Repositories
-
-The following repos use these shared org-level secrets in their CI workflows:
-
-- rock/riotpiao.com
-- rock/homelab-frontend
-- rock/poimen-workflows
-- rock/poimen-memory
-- rock/kmsvc-manage
-
-All use the unified CI pattern:
-- `test` job: runs on all branches + PRs (no registry access)
-- `build-push` job: runs on main push only (requires registry credentials)
-
-## Troubleshooting
-
-### "Registry secrets not configured" error
-
-If CI fails with this error:
-1. Check org settings: https://forgejo.riotpiao.com/rock/settings/actions/secrets
-2. Verify both secrets exist and are not empty
-3. Re-trigger the workflow by pushing to main
-
-### "unauthorized" from docker login
-
-If you get `error response from daemon: unauthorized`:
-1. Check the token value is correct (copy-paste carefully)
-2. Verify token has `read:registry` and `write:registry` scopes
-3. Generate a new token if the old one expired
