Fix 2026-07-22: local .NET admin (C:\sites\stostayer\Web.config) S3 providers
re-pointed to stostayer MinIO. 3 bugs in original config: wrong creds
(AKIAJ2YJP72W6ZHCRE6Q = books-vds root, not stayer_minio), wrong endpoint
(minio.stostayer.ru is not S3 API port; prod uses minio-api.stostayer.ru),
wrong region (local -> AmazonS3Exception expecting us-west-1). Creds NOT in
pass — live in stostayer.new config/default.json. Admin now shares prod
storage; manual App_Data mirroring retired.
+ index.md, log.md. Also carries pending handoff (NEXT_SESSION) + runbook
update from 2026-07-21 stostayer-web 0.3.20 deploy session.
