Bootstrap Homelab-Docs wiki

Initial documentation of the hubris Proxmox homelab as a cross-linked
markdown wiki. Per-node pages, cross-cutting infrastructure pages, an
investigation log, and an operations cheatsheet. Each node and topic
ends with a Changelog section so changes can be tracked in-place going
forward.

Refreshed against live state on 2026-04-28 — 14 active LXCs (109
syncthing currently stopped) + 1 VM (108 haos). Reflects post-A/B-test
state of the 2026-04-21 hubris crash-loop investigation.

+
+## Auth
+Behind [Authentik forward-auth](124-authentik.md). API path `/api/*` bypasses forward-auth (mobile clients can't follow the browser login redirect; bearer token still enforces auth on `/api`). Header propagation: `PAPERLESS_ENABLE_HTTP_REMOTE_USER=true` and `PAPERLESS_HTTP_REMOTE_USER_HEADER_NAME=HTTP_X_AUTHENTIK_USERNAME` in `/opt/paperless/paperless.conf`. Django auto-creates matching users on first SSO login.
+
+## Storage
+- Documents at `/mnt/library/documents` (owner `www-data:www-data`, mode 750 — *not* on the `media` group, by design).
+
+## Known issues
+- Disk usage was 86.9% at last claudio-monitor reading on 2026-04-21. Monitor or grow rootfs.
