 ## Session History
 
+### Session 2026-04-12
+- **Phase**: Emacs/iPad integration fixes
+- **VPS**: home-apps
+- **Repository**: homelab-agents
+- **Accomplishments**:
+  - Fixed Emacs init error in `flashcard-config.el` (mismatched parenthesis causing void-variable crash)
+  - Fixed cross-platform load paths in `flashcard-config.el` and `task-config.el` (Mac vs VM paths)
+  - Added `~/.emacs.d/secrets.el` symlink
+  - Fixed ELPA package visibility by adding `~/emacs_config/elpa` to `package-directory-list` on Linux
+  - Added `mermaid-mode` package alongside existing `ob-mermaid`
+  - Fixed Puppeteer/Chromium sandbox error for mermaid rendering on Linux VM
+  - Investigated and confirmed Notion credentials path resolves correctly
+  - Set up `.netrc` on home-apps for Gitea authentication (both public domain and internal IP)
+  - Bootstrapped home-apps into the homelab-agents workflow
+- **Key Decisions**:
+  - Conditional `darwin`/Linux load paths keep one config file working on both platforms
+  - Puppeteer config file acts as a feature flag — presence enables `--no-sandbox`, absence is safe
+  - `.netrc` requires two entries when scripts use internal IP for git operations
+- **Next Steps** (Prioritized):
+  - Test mermaid rendering end-to-end on iPad (compile + Babel blocks)
+  - Verify Notion Tasks opens cleanly
+  - Install `mermaid-mode` on Mac via `M-x package-install`
+
