CC-025 Phase 4A — Quartz Graph Viewer

Scope: Only Phase 4A executed per Elliott’s explicit instruction (Phase 4B/4C and all cc_queue.md tasks skipped this session).

Built

  • Quartz v5.0.0 cloned to /home/eco/second-brain-quartz, content symlinked to /home/eco/second-brain/notes.
  • Deviation from briefing: system npm was 9.2.0, Quartz 5.0.0 requires npm >=10.9.2. Installed a user-local Node 22.23.1 + npm 10.9.8 via nvm (already present at ~/.nvm, unused) rather than touching the system Node/npm other sessions may depend on.
  • Deviation from briefing: Quartz 5.0.0 uses quartz.config.yaml + quartz.ts, not the quartz.config.ts/quartz.layout.ts the briefing described (older Quartz version). Graph component (github:quartz-community/graph) was already enabled by default — no extra config needed. Set pageTitle: "Elliott's Second Brain".
  • Deviation from briefing (nginx skipped): nginx is not installed on eco-chi-001 (it only exists on the VPS) and per /home/eco/CLAUDE.md this box is the primary compute node, not a place to introduce a new system service casually. Quartz 5.0.0 ships native --serve --watch flags that serve the static build over HTTP and auto-rebuild on file change in one process — this replaces both the “nginx serves static files” step and the separate inotifywait systemd unit from the briefing with a single simpler mechanism.
  • systemd unit /etc/systemd/system/quartz-second-brain.service — runs npx quartz build --serve --watch --port 8080 as eco, Restart=always, enabled at boot.

Verified live

  • systemctl status quartz-second-brain — active/running.
  • Reachable at http://localhost:8080, http://192.168.12.12:8080 (LAN), and http://100.85.58.103:8080 (Tailscale) — HTTP 200 on all three.
  • contentIndex.json shows 46 nodes with real wikilink edges (e.g. index.md → 9 agent entity pages) — confirms wikilinks render as graph edges.
  • Auto-rebuild: created notes/tech/test-quartz.md with a [[hermes]] link — log showed “Detected change, rebuilding…” within ~4 seconds, rebuild completed in 132ms (well under the 60s target). Deletion of the same file also triggered a correct rebuild. Test file removed after verification.

Not verified (needs Elliott)

  • Actual phone-browser rendering, tap-to-navigate, and touch pan/zoom on the graph — I have no way to drive a real mobile browser from this session. Please open http://100.85.58.103:8080 (or the LAN IP http://192.168.12.12:8080) on the Samsung phone over Tailscale/LAN and confirm the graph is visually correct and touch-interactive.

Phase 4A done-criteria status

  1. Quartz builds from notes/ ✅
  2. Graph loads on phone browser — server-side confirmed reachable; visual/touch confirmation pending Elliott ⏳
  3. Wikilinks render as graph edges ✅ (confirmed via contentIndex.json)
  4. Auto-rebuild watcher running ✅ (systemd, --watch flag, live-tested)
  5. New note → graph update within 60s ✅ (observed ~4s)

Fireman not run for this task — no app code touched (this session’s separate, paused ADMIN_KEY code fixes are a different task, not committed).
