dtoro 8a6422bd7d docs: move narrative wiki under knowledge/wiki/ (phase 3)

Problem: node and cross-cutting narratives lived at the repo root
(containers/, vms/, infrastructure/, host .md files), interleaved with the
machine-readable substrate.

Change:
- Move containers/ -> knowledge/wiki/containers/, vms/ -> knowledge/wiki/vms/,
  infrastructure/ -> knowledge/wiki/infrastructure/, hosts/{hubris,strong}.md ->
  knowledge/wiki/hosts/, infrastructure/references/ -> knowledge/sources/references/,
  GLOSSARY.md -> knowledge/GLOSSARY.md.
- Add knowledge/{index.md,log.md,sources/index.md} scaffolding.
- Rewrite all relative links repo-wide via a path-resolving mapper (inbound +
  outbound + between-moved-files), including .hermes/, runbooks, operations,
  investigations, plans, README, AGENTS.
- Repoint inventory.yaml doc_page fields and regenerate hosts/*.yaml (which
  embed doc_page); update oikos/gen-topology.py output path, candidate doc
  paths, and footer links; update code-comment doc paths.

Substrate untouched in place: inventory.yaml, hosts/*.yaml (regenerated,
idempotent), oikos/ code, mcp/, secrets/, bin/.

Verification:
- Logical broken-link set identical to pre-move baseline (net 128 -> 127; the
  topology regen fixed one, introduced none). Remaining are pre-existing refs
  to destroyed/archived nodes, out of scope for this move.
- gen-topology.py --check exit 0 (in sync); cards carry knowledge/wiki/ doc paths.
- build_host_files.py idempotent; all inventory doc_page targets resolve.
- MCP contract verified: get_page/search_docs/get_changelog resolve moved pages.

Investigation: Caddyfile truncation — all LAN services down (2026-06-06)

Date: 2026-06-06 Status: resolved Duration: ~10 hours (from last known good state ~12:39 UTC to restoration ~22:40 UTC)

Symptom

All *.hubris.network URLs except photos.hubris.network and auth.hubris.network returned tlsv1 alert internal error or TCP timeouts from LAN/mesh clients. dig @192.168.8.2 and dig @100.122.255.254 both resolved to 192.168.8.175 correctly — DNS was fine. The issue was at the Caddy level.

Root cause

The Caddyfile on LXC 121 was manually edited directly on the filesystem (not via the dtoro/caddy-conf git repo), reducing it from 260 lines/30+ site blocks to 43 lines with only 3 photo-related site blocks: photos.hubris.network, prism.hubris.network, and photos2.hubris.network.

Timeline

Time (UTC+2)	Event
Jun 04 23:43	Last successful git-push deploy — full Caddyfile (260 lines)
Jun 06 ~12:00	Caddyfile manually edited locally, truncating to 3 sites
Jun 06 12:39	Deploy webhook triggered → `git pull --ff-only` failed: "Your local changes would be overwritten"
Jun 06 14:13	Deploy webhook triggered again → `deploy ok` (the truncated file was committed or merged somehow)
Jun 06 22:34	Investigation began
Jun 06 22:43	Caddyfile restored from `origin/master`, `systemctl reload caddy`

Evidence

git diff HEAD -- Caddyfile on LXC 121: +3 / -159 lines
Git reflog: HEAD at 32575ce (fix: sab port 8081→8082), working tree diverged
Backup file Caddyfile.bak.1780263919: 225 lines, full original config
git stash list shows one auto-stash entry
origin/master at 1b977aa: 260 lines, all site blocks present

Secondary root cause found during investigation

elementsynapse (LXC 118) had iface eth0 inet dhcp internally despite pct set 118 --net0 ... ip=192.168.8.239/24. On DHCP lease renewal, dhclient grabbed .244 from Technitium's pool. Caddy's reverse_proxy 192.168.8.239:8008 was hitting a dead IP.

This is the same class of drift as the June 5th incidents (paperless, HAOS, apps, mule-images). Elementsynapse was missed during the 2026-06-02 static-IP migration.

Fix applied

Caddyfile → git checkout --force origin/master -- Caddyfile + systemctl reload caddy
elementsynapse → replaced iface eth0 inet dhcp with static, killed dhclient, verified connectivity

Permanent safeguards (all deployed)

Safeguard	Location	What it does
Site-count guard	`/etc/caddy/scripts/deploy.sh`	Refuses reload if <20 `hubris.network` site blocks
Dirty-tree auto-stash	`/etc/caddy/scripts/deploy.sh`	Stashes local edits before git pull
Auto-backup	`/etc/caddy/scripts/deploy.sh`	Saves Caddyfile.bak. before any change, keeps 5
Caddy backend health	`/etc/cron.d/caddy-backend-health` on hubris	Runs `check-caddy-backends.sh` every 10 min
DNS sync	`/etc/cron.d/dns-sync` on LXC 107	Runs `dns-sync.py` every 10 min (was missing since 2026-06-04)
