Erich Blume 6b84a5688e Add docs/ directory with blumeops zk cards

Move 21 blumeops-tagged zettelkasten cards from ~/code/personal/zk/
to docs/ in this repository. These files are symlinked back into the
zk at ~/code/personal/zk/blumeops for seamless obsidian.nvim integration.

This enables:
- Git-managed documentation in the blumeops repo
- Preserved wiki links between blumeops docs
- obsidian-sync isolation (docs don't sync to other devices)
- Direct editing via obsidian.nvim with the blumeops workspace

Also updates zk-docs mise task to read from local docs/ directory.

Jellyfin Management Log

Jellyfin is a free, open-source media server running natively on indri for full VideoToolbox hardware transcoding support.

Service Details

URL: https://jellyfin.ops.eblu.me
Port: 8096 (localhost only, proxied via Caddy)
Data directory: ~/Library/Application Support/jellyfin
Media path: /Volumes/allisonflix (NFS from sifaka)
LaunchAgent: mcquack.jellyfin

Useful Commands

# Check LaunchAgent status
ssh indri 'launchctl list | grep jellyfin'

# View logs
ssh indri 'tail -f ~/Library/Logs/mcquack.jellyfin.err.log'

# Check port is listening
ssh indri 'lsof -nP -iTCP:8096 -sTCP:LISTEN'

# Restart Jellyfin
ssh indri 'launchctl unload ~/Library/LaunchAgents/mcquack.jellyfin.plist && launchctl load ~/Library/LaunchAgents/mcquack.jellyfin.plist'

# Check metrics
ssh indri 'cat /opt/homebrew/var/node_exporter/textfile/jellyfin.prom'

Hardware Transcoding

Jellyfin uses Apple VideoToolbox for hardware-accelerated transcoding on the M1 Mac Mini.

Capabilities:

H.264 encode/decode: Hardware
HEVC (H.265) encode/decode: Hardware
AV1 decode: Software only (requires M3+)
HDR to SDR tone mapping: VPP (hardware)
Concurrent 4K streams: ~3 with HDR tonemapping

Configuration (Dashboard > Playback):

Hardware Acceleration: Apple VideoToolbox
Allow hardware encoding: Enabled
VPP Tone mapping: Enabled (for HDR to SDR)

Observability

Metrics: Collected via jellyfin_metrics ansible role to Prometheus textfile
Logs: Forwarded to Loki via Alloy (service="jellyfin")
Dashboard: "Jellyfin Media Server" in Grafana

Metrics collected:

jellyfin_up - Server availability
jellyfin_version_info - Server version
jellyfin_library_items{library,type} - Library counts
jellyfin_sessions_total - Active sessions
jellyfin_sessions_playing - Playing sessions
jellyfin_transcode_sessions_total - Transcoding sessions

API Key Setup

Metrics collection requires an API key:

Open https://jellyfin.ops.eblu.me
Go to Dashboard > API Keys > Add
Create key with description "metrics"
Save to indri:

ssh indri 'echo "YOUR_API_KEY" > ~/.jellyfin-api-key && chmod 600 ~/.jellyfin-api-key'
