…lign VMID scheme
Add two portable-pattern pages: the single-filesystem media storage
layout (two-dataset EXDEV/duplication/quota-death-spiral anti-pattern,
one /data dataset with torrents/ + media/ subtrees, shared group +
setgid, min-free/auto-restart/capacity-alert resilience, 5x seeding)
and the tier-named ZFS pool convention (rpool/bulk/fast — names encode
the storage tier, never node/RAID/drive-count, so dataset paths are
node-agnostic and replicas line up by construction).
Align the VMID positional scheme with the locked spec: digit order
[Tier][Sub][Crit][Instance][OS][Env], OS family digits (4 = LXC),
env 0-4, worked example 703040. Document the deterministic-MAC DHCP
reservation pattern (02: + hostname digest -> reservation -> DNS A
record; {mac, reserved_ip} flow through the IaC inventory contract).
Cross-link the media stack page to the storage layout.

Summary
Documents two reusable homelab storage patterns and brings the VMID page up to the locked spec.
New pages
EXDEVkills hardlinks → silent copy fallback → every seeded item duplicated → download quota fills → torrent client dies), and the TRaSH-guides fix: one dataset bind-mounted at/datawithtorrents/{movies,tv}+media/{movies,tv},recordsize=1M, shared group + setgid, plus the resilience ladder (systemdRestart=on-failure, *arr min-free-space, >85% capacity alerts, start-on-boot) and 5× good-steward seeding (free in disk because seed == library).rpoolboot /bulkHDD raidz /fastflash). Pool names encode only the performance tier — never node, RAID level, or drive count — so dataset paths are identical on every node and replicas line up by construction.Updated pages
[Tier][Sub][Crit][Instance][OS][Env], OS family digits (4 = LXC, 3 = Docker, …), env values 0–4, worked example703040; new deterministic-MAC DHCP reservation section (locally-administered02:+ hostname-digest MAC → controller reservation → DNS A record owns the address;{mac, reserved_ip}flow through the IaC inventory contract).Validation
jq empty docs.json— passmint broken-links— no broken linksscripts/validate-mermaid.sh— pass (canonical init directive count still 1)Public-pattern page only — placeholder CIDR shapes, no real addresses, nodes referenced generically.
