 - Server `qsfera_full` compose files now require explicit admin, Keycloak, and S3/MinIO secrets instead of demo defaults.
 - Server `qsfera_full/env.production.example` provides a tracked production-safe starting point with TLS validation enabled and demo users disabled.
 - Server `qsfera_full/validate-production-env.sh` checks production `.env` invariants before compose validation: TLS validation enabled, demo users disabled, pinned production image, required domains, required secrets, and no public-production MinIO.
+- Added `scripts/validate-server-production-env.ps1` with the same `qsfera_full` production `.env` checks for the local Windows/PowerShell workflow; it validates required domains, release image pinning, disabled demo/insecure modes, required secrets, optional Keycloak/S3 blocks, and backup-friendly config/data path warnings without printing secret values.
+- `scripts/validate-server-production-env.ps1` was verified on 2026-06-12: it rejects `Server/devtools/deployments/qsfera_full/env.production.example` with placeholder values and accepts a temporary filled production-shaped env file with `0 warning(s)`.
 - Server now has a Raspberry Pi 5 Docker path matching the Ikar/Argus deployment style: `Server/docker-compose.rpi5.yml`, `Server/.env.example`, and `Server/docs/raspberry-pi-5-docker.md`.
 - Server Docker builds now accept explicit production metadata for `QSFERA_VERSION`, `QSFERA_EDITION`, and `QSFERA_BUILD_DATE`, and the Raspberry Pi 5 compose path defaults to pinned image `qsfera-cloud-server:7.0.0-rpi5-stable`.
 - Windows/Desktop update channel defaults now match the build channel: stable builds default to `stable`, beta builds default to `beta`.

 - Back up the gitignored Android release signing files created under `Android/signing/` and `Android/argus-signing.local.properties` in a secure external secret store. Without this key material, future in-place Android updates from the production-signed `1.3.13` cannot be signed with the same certificate.
 - Provide CI/Argus signing secrets derived from the same release key: `QSFERA_RELEASE_KEYSTORE`, `QSFERA_RELEASE_KEYSTORE_PASSWORD`, `QSFERA_RELEASE_KEY_ALIAS`, and `QSFERA_RELEASE_KEY_PASSWORD`.
 - Fill production domains, ACME email, admin passwords, Keycloak passwords, and storage secrets from a secret manager. Do not commit real values.
-- Run `./validate-production-env.sh .env` and then `docker compose config` for `Server/devtools/deployments/qsfera_full` with a filled production `.env`; Docker CLI is not available in this local environment, so compose rendering is not locally verified.

 - Provide real Windows signing secrets in CI: `QSFERA_DESKTOP_SIGN_PACKAGE=True` and `QSFERA_DESKTOP_CODESIGN_CERTIFICATE` with the Craft-compatible signing certificate reference. The current local MSI is intentionally not published as a production update because `Get-AuthenticodeSignature` reports `NotSigned` and `Desktop/scripts/validate-production-release.ps1 -RequireSigning` fails until signing is configured.
 - Publish the first signed Windows MSI with `scripts/publish-windows-desktop.ps1 -RemoteHost ...` and update `https://qsfera.kusoft.xyz/desktop/updates/stable.xml` from the current no-update XML to a concrete `<version>`, `<versionstring>`, and HTTPS `.msi` `<downloadurl>`.
