Erich Blume 7112297150 Move zk cards to docs/zk/ for documentation restructuring

Phase 1 of docs restructuring: move all zettelkasten cards to a
temporary docs/zk/ subdirectory while preparing to build a new
Diataxis-based documentation structure.

- Move all existing markdown files from docs/ to docs/zk/
- Update zk-docs mise task to look in the new location
- Add docs/README.md explaining the restructuring plan

Indri Maintenance Log

Indri is a Mac Mini M1 (2020) serving as the primary 1767747119-YCPO server.

Host Details

Model: Mac mini M1, 2020 (Macmini9,1)
Storage: 2TB internal SSD
macOS: 15.7.3 (Sequoia)
Role: Primary server for homelab services

Passwordless Sudo

Configured passwordless sudo for erichblume user to allow ansible become: true tasks to run without password prompts:

# Config at /etc/sudoers.d/erichblume
erichblume ALL=(ALL) NOPASSWD: ALL

This is acceptable given the security model - tailnet access is the trust boundary.

Sleep Prevention

Indri must stay awake to serve network requests. Currently using Amphetamine (App Store) to prevent sleep.

Configuration:

Start Session At Launch: enabled
Default Duration: indefinite
Allow Closed-Display Sleep: enabled (no display attached)

Known Issue: Amphetamine can crash after extended uptime (~12 days observed), leaving the system unprotected. If this becomes a recurring problem, consider switching to system-level sleep prevention:

# Option 1: Disable sleep via pmset (requires sudo)
sudo pmset -c sleep 0 displaysleep 0

# Option 2: Use caffeinate daemon via LaunchAgent
# Create ~/Library/LaunchAgents/com.local.caffeinate.plist
caffeinate -s  # -s = prevent sleep on AC power

These could be managed via ansible for reliability.

System went to sleep at 19:20, stayed asleep overnight
Discovered when services were unreachable; manually restarted Amphetamine at ~07:30
Crash report: ~/Library/Logs/DiagnosticReports/Amphetamine-2026-01-19-190921.ips
Root cause: Memory management bug in Amphetamine during long-running session (~12 days uptime)
Action: Monitoring for now; if recurs, will implement pmset/caffeinate via ansible
