+## Deployment problems and solutions
+
+**1. Workflow YAML syntax error**
+The SSH heredoc (`<< 'EOF'`) inside a YAML `run:` block conflicted with YAML parsing — red triangle in Gitea, no logs.
+→ Replaced with a quoted multiline SSH string.
+
+**2. Runner not picking up jobs**
+The workflow used `container: debian:bookworm-slim` just to get SSH, forcing the runner to pull a Docker image on every run.
+→ Removed the container block, reverted to `runs-on: ubuntu-latest` using the cached runner image.
+
+**3. Runner was repo-scoped, not user-scoped**
+The act_runner was registered specifically for another repo. stAndrews showed zero runners and jobs stayed queued forever.
+→ Re-registered the runner at the user level via Gitea User Settings → Actions → Runners.
+
+**4. Two runner instances competing**
+A manual `pkill` + manual restart created a second runner process alongside the systemd service, both sharing the same UUID.
+→ Killed the duplicate, leaving only the systemd-managed instance.
+
+**5. Gateway Caddyfile `import` silently failing**
+The `import /data/projects/r/*/Caddyfile.snippet` directive was never evaluated — the gateway container only mounts the Caddyfile itself, not the project directories.
+→ Added the stAndrews route directly to the gateway Caddyfile.
+
+**6. renv activating inside the container**
+The volume mount `.:/srv/shiny-server` put `.Rprofile` into the container, triggering renv to try installing its own library and conflicting with packages already installed in the image.
+→ Switched to selective mounts (`./data` and `./www` only). App code is baked into the image; only runtime data is volume-mounted.
+
+**7. `owners.rds` deleted from disk**
+`git rm --cached data/owners.rds` removed it from git tracking but also wiped the file from the filesystem.
+→ Ran `update_owners.R` inside the rstudio container to rebuild it from the SCPA source.
