11554d45ac wiki(ingest): vds-kzntsv network-stack mismatch RCA + ifupdown anti-pattern 
Incident 2026-05-28 ~05:45–13:52 MSK на vds-kzntsv. ~2.5ч активного outage
+ ~5.5ч на эфемерной статике до окончательного fix хостером.

Revised RCA: наш netplan+systemd-networkd конфликтовал с provider's expected
ifupdown stack. Их start/ipadd procedure ожидает чистый ifupdown и не может
auto-recover когда networkd «держит» eth0. 8 дней работало потому что
networkd сам тянул DHCP. Когда что-то на стороне Rusonyx разорвало
DHCP-binding — auto-recovery не сработала.

Fix: systemctl mask netplan + systemd-networkd* (на running system без stop —
IP и SSH сохранились), Rusonyx ребутнул VM и положил чистый
/etc/network/interfaces.d/ifcfg-eth0 через свой start/ipadd. Netmask /18,
gw 89.253.192.1, чистый ifupdown.

Wiki:
- NEW concepts/vds-kzntsv-dhcp-outage-2026-05-28 — full RCA + recovery
  runbook (эфемерная статика + permanent-fix via ifupdown) + diagnostic
  dot-graph + revised lessons-learned + anti-pattern
- NEW sources/vds-kzntsv-incident-2026-05-28 — timeline 05:25 backup OK →
  08:43 statics → 13:52 final reset; provider's ifcfg-eth0 content; ticket
  text reference
- UPDATE entities/vds-kzntsv — mask /18, ifupdown stack, kernel cmdline
  net.ifnames=0 объясняет eth0 naming, hypervisor hw80, pass-store путь,
  Known issues §
- UPDATE concepts/rusonyx-vps-onboarding-quirks — quirk #9 переписан про
  /18 layout + canonical ifcfg, quirk #10 NEW про ifupdown vs netplan
  stack choice + bootstrap mask commands
- UPDATE index.md + log.md

Tasks:
- STATUS header: incident RESOLVED summary
- NEXT_SESSION: следующая сессия — cleanup netplan-artifacts (optional),
  registry GC (~20G pending), board-viewer-build unhealthy разбор

Memory (out-of-repo): vds-kzntsv-rusonyx-network-recovery переписан с
revised RCA — canonical bootstrap step «mask netplan/networkd» для всех
Rusonyx Ubuntu VDS.

74cf219533 wiki(concepts): ingest ocis-on-vds-deploy-recipe + entity refresh 
New concept page documents the oCIS-on-VDS deploy pattern with the 4
non-obvious gotchas surfaced during owncloud-vds-deploy:

  1. UID mismatch — image ocis-user is 1000, host vitya is 1001 →
     compose `user: "1001:1001"` override (alt chown rejected as orphan-UID)
  2. PROXY_TLS=false — explicit per docs when reverse proxy terminates HTTPS
  3. PROXY_ENABLE_BASIC_AUTH=true — required for WebDAV/LibreGraph API
  4. LibreGraph POST /graph/v1.0/users — only way to create users (no CLI)

Plus decomposedfs storage layout, atomic-revert recipe, backup integration
note. Source: .tasks/owncloud-vds-deploy.md.

entities/vds-kzntsv.md updated: stack table + hostnames + file layout
include owncloud row.

index.md catalog + log.md ingest entry refreshed.
