 - 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.
 - 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`.
 - Windows/Desktop CI now validates production release invariants before Windows packaging and requires signing variables for stable tag releases.
 
 ## Raspberry Pi 5 Check
 
 - Pi target checked on 2026-06-08: `192.168.0.185` reports `aarch64`, 64-bit Debian 13, Docker `29.4.3`, Docker Compose `v5.1.3`, and Docker server architecture `aarch64`.
-- Current QSfera server is already running on that Pi as `qsfera-cloud-server:rpi5-local`, with `Arch=arm64`, bind-mounted config/data under `/mnt/data/qsfera/cloud-server`, and loopback port `127.0.0.1:9200`.
-- `https://qsfera.kusoft.xyz/status.php` returned HTTP `200` during the check.
-- The Pi root filesystem is nearly full: `/dev/mmcblk0p2` reported `57G` size, `52G` used, `2.4G` available, `96%` use. `/mnt/data` reported `916G` size, `18G` used, `853G` available, `2%` use.
+- Before stable-image deployment, the old Pi server was running as local/dev image `qsfera-cloud-server:rpi5-local`; public `/status.php` reported `edition: dev` and `productversion: 7.0.0`.
+- The Pi server now runs through `/mnt/data/qsfera/cloud-server/src/docker-compose.rpi5.yml` with pinned image `qsfera-cloud-server:7.0.0-rpi5-stable`, bind-mounted config/data under `/mnt/data/qsfera/cloud-server`, and loopback port `127.0.0.1:9200`.
 - Before switching the Pi server to compose, config/data were backed up to `/mnt/data/qsfera/backups/cloud-server-before-compose-20260608-200921.tar.gz`. The archive was created with `sudo tar`, had size `213M`, and `tar -tzf` completed successfully.
-- The Pi server now runs through `/mnt/data/qsfera/cloud-server/src/docker-compose.rpi5.yml` with `docker compose`. `docker compose ps` reported `qsfera-cloud-server` as `Up` and `healthy`, still bound to `127.0.0.1:9200`.
-- This is now compose-managed on the Pi, but I do not count it as fully production-ready yet because the running image is still a local/dev build (`qsfera-cloud-server:rpi5-local`, external status reports `edition: dev`) rather than a pinned production release image.
+- Before switching to the stable image, config/data were backed up to `/mnt/data/qsfera/backups/cloud-server-before-stable-image-20260608-201536.tar.gz`. The archive had size `213M`, and `tar -tzf` completed successfully.
+- `docker run --rm --entrypoint /usr/bin/qsfera qsfera-cloud-server:7.0.0-rpi5-stable version --skip-services` returned `Version: 7.0.0`, `Edition: stable`, and `Compiled: 2026-06-08 00:00:00 +0000 UTC`.
+- After deployment, `docker compose ps` reported `qsfera-cloud-server` as `Up` and `healthy`; `docker inspect` reported `IMAGE=qsfera-cloud-server:7.0.0-rpi5-stable HEALTH=healthy`.
+- Local `https://127.0.0.1:9200/status.php` and public `https://qsfera.kusoft.xyz/status.php` both returned `edition: stable` and `productversion: 7.0.0`; the public request returned HTTP `200`.
+- After Docker builder cache cleanup and the stable deployment, `/dev/mmcblk0p2` reported `57G` size, `12G` used, `43G` available, `21%` use. `/mnt/data` reported `916G` size, `18G` used, `852G` available, `3%` use.

 - Decide the rollout policy for any devices that installed the debug-signed Argus `1.3.5` APK. The production-signed `1.3.6` APK is the correct current release, but installed debug-signed clients will not satisfy the app's own signer-digest check for an in-place update.
 - 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.
