Migration to vds-kzntsv confirmed by operator. Off-LAN check from the
IIS host itself: emspb.ru + www.emspb.ru -> 89.253.255.94 HTTP 200.
Removed only the two migrated SNI bindings (26->24 total); emspb.snolla.com
retained (not migrated, DNS still -> IIS). Config backup taken:
pre-emspb-decommission-2026-07-02. Site snolla + apppool Started, other 23
hosts untouched. win-acme is binding-driven (--source iis) so next renewal
auto-drops the emspb.ru SANs.

Root cause (NOT a migration defect): MoreThenCms tenant `maljarka`
had `dbo.Sites.SettingsData = NULL` (no `httpSecure` block) -> on a
real HTTPS request SnollaMiddleware throws KeyNotFoundException ->
502. HTTP served 200 fine. DNS/TLS/IIS binding all correct.
Fix applied to shared MSSQL (mssql.kzntsv.site): UPDATE Sites set
SettingsData with httpSecure{enableHttps:true,...} + recycle snolla
pool. Verified 443->200 server-local and external via 80.64.31.36;
kupimknigi untouched. Audit: maljarka was the only NULL-settings
site with a :443 binding (of 25); rimiz degraded for another reason.
- new concept: morethencms-null-settingsdata-https-502
- entities/ruvds-iis-host: maljarka moved from Degraded -> fixed
- index.md + log.md + STATUS.md + NEXT_SESSION.md updated
