 Formal releases publish `ghcr.io/eezd/rawmark:<version>` for Linux amd64 and arm64. The earlier releases were withdrawn; `VERSION` alone does not mean a version is available. Check the Releases page and package visibility before using the example version below. Replace `rawmark` in the Docker commands above with that image name to skip source builds. `latest` follows the latest stable release; use a version tag for controlled upgrades. The repository Compose file continues to support source builds.

 - Git mirroring runs independently on push/create/delete, hourly reconciliation and manual retry, sharing `/docker/gitea/mirrors/RawMark/.mirror.lock`. Only business branches, tags and complete history are mirrored, including deletions. Control code comes from main. Enable `RAWMARK_MIRROR_ENABLED=true` after the main cutover and configure the account-level `ALL_GITHUB_TOKEN` in Gitea user Settings → Actions → Secrets with repository/workflow write access. DEV images never go to GHCR.
 - `RAWMARK_GITEA_TOKEN` requires repository and Packages write access. Keep runner capacity one and sweep disabled; only trusted code runs on this Docker-socket runner. Install toolchains inside CI containers and clean only resources labeled for the current attempt.
 - `RAWMARK_BUILD_CHANNEL=development` derives a consistent frontend/binary version without editing the formal VERSION file. Development archives use `RawMark_<version>_linux_amd64.tar.gz`; historical release artifacts retain their names. Keep the existing 90,000,000-byte transfer budget.
-- Formal release and production workflows are temporarily disabled pending gitea-release adaptation; future publication must share Git mirror serialization. Production data and paths remain unchanged. Keep the old GitHub Release workflow disabled and preserve the current Pages Demo.
+- Formal releases run manually from trusted main, require successful main-push CI, and publish six native packages plus Linux amd64/arm64 images with date/hash versions. Fixed release IDs retain resumable checkpoints under the persistent release lock. After both releases and public GHCR digest pulls pass, MAIN deploys to `/docker/gitea/main/RawMark` as `RawMark-main` (project `rawmark-main`). Keep Pages unchanged.

 - Git 镜像独立于 CI 成败：push/create/delete、每小时对账和手动重试，共用 `/docker/gitea/mirrors/RawMark/.mirror.lock`，仅同步业务分支和 TAG 及完整历史，跟随源端删除。同步代码从 main 读取；`RAWMARK_MIRROR_ENABLED=true` 后启用，凭据统一使用 Gitea 账号级 Secret `ALL_GITHUB_TOKEN`（头像 → 设置 → Actions → 密钥），接入前配置并验证实际权限，仓库级同名项会覆盖账号级值。DEV 镜像不上传 GHCR。main 切换前保持该变量关闭。
 - CI 凭据 `RAWMARK_GITEA_TOKEN` 需要仓库和 Packages 写权限。runner 保持容量一、`sweep: false`，只运行受信代码；工具链安装在任务容器。资源按任务标签清理，禁止全局 prune。
 - 开发构建通过 `RAWMARK_BUILD_CHANNEL=development` 派生版本，前端与二进制一致；正式 `VERSION` 不因开发构建改变。开发包为 `RawMark_<版本>_linux_amd64.tar.gz`；历史正式产物不改名。安装包及单次传输保持既有 90,000,000 字节预算。
-- 正式发布与生产入口暂时禁用，后续由 gitea-release 适配，不能绕过 Git 镜像锁直接写 GitHub 分支。生产保留现有目录和数据，不随开发推送更新；GitHub 旧 Release workflow 保持禁用，Pages Demo 不切换。
+- 正式发布从受信 main 手动触发，要求候选完整 SHA 的 main push CI 成功；日期哈希版本用于六平台包和 Linux 双架构镜像。固定发布 ID 与持久锁保证可续跑；双端发布和公开 GHCR 摘要拉取验收后自动部署 MAIN：`/docker/gitea/main/RawMark`、`RawMark-main`、`rawmark-main`。Pages 保持原配置。
