+On every push to `main`, the workflow updates the configured Cloud Run service or services with the values above and removes legacy env vars that should now live in the account-group config (`IB_CLIENT_ID`, `IB_GATEWAY_INSTANCE_NAME`, `IB_GATEWAY_MODE`) plus the older transport vars (`IB_GATEWAY_HOST`, `IB_GATEWAY_PORT`, `TELEGRAM_CHAT_ID`). If `IB_GATEWAY_ZONE` or `IB_GATEWAY_IP_MODE` are blank in GitHub, the workflow also removes them from Cloud Run to avoid drift.
 
 `STRATEGY_PROFILE` is resolved from a platform capability matrix plus a rollout allowlist derived from `runtime_enabled` strategy metadata. The current strategy domain is `us_equity`: `eligible` means the platform can run the strategy in theory, while `enabled` means the current rollout really allows it. `ACCOUNT_GROUP` selects one account-group config entry, and the service fails fast if that runtime identity is incomplete. `RUNTIME_TARGET_JSON` carries the structured runtime identity; strategy defaults continue to come from `UsEquityStrategies`.
 
 Important:
 
 - The workflow only becomes strict when `ENABLE_GITHUB_ENV_SYNC=true`. If this variable is unset, the sync job is skipped. When enabled, it resolves the selected profile's snapshot/config requirements from `scripts/print_strategy_profile_status.py --json` instead of a hard-coded strategy-name list.
+- For slot deployments, configure `CLOUD_RUN_SERVICES` instead of the legacy `CLOUD_RUN_SERVICE`. Do not enable the workflow until the GitHub runtime variables describe every selected slot correctly; otherwise one shared `RUNTIME_TARGET_JSON` can overwrite per-slot runtime identity.
 - Here "shared config" still only means the **IBKR pair** (`InteractiveBrokersPlatform` + `IBKRGatewayManager`). `TELEGRAM_TOKEN` and `TELEGRAM_TOKEN_SECRET_NAME` remain repository-specific. If crisis alert recipients and sender policy are shared across platforms, manage `CRISIS_ALERT_CHANNELS`, `CRISIS_ALERT_EMAIL_*`, and `CRISIS_ALERT_PUSH_*` with GitHub Organization Variables/Secrets or GCP Secret Manager.
 - If `IB_ACCOUNT_GROUP_CONFIG_SECRET_NAME` is set, the Cloud Run runtime needs Secret Manager access to that secret.
 - GitHub now authenticates to Google Cloud with OIDC + Workload Identity Federation, so `GCP_SA_KEY` is no longer required for this workflow.

+每次 push 到 `main` 时，这个 workflow 会把上面这些值同步到配置的一个或多个 Cloud Run 服务里，并清掉已经转移到账号组配置里的旧 env（`IB_CLIENT_ID`、`IB_GATEWAY_INSTANCE_NAME`、`IB_GATEWAY_MODE`）以及更早的传输层 env（`IB_GATEWAY_HOST`、`IB_GATEWAY_PORT`、`TELEGRAM_CHAT_ID`）。如果 GitHub 里没有配置 `IB_GATEWAY_ZONE` 或 `IB_GATEWAY_IP_MODE`，workflow 也会把 Cloud Run 上这两个旧值一起删除，避免双配置源漂移。
 
 `STRATEGY_PROFILE` 由平台能力矩阵和从 `runtime_enabled` 策略元数据派生的 rollout allowlist 一起决定。当前策略域仍是 `us_equity`：`eligible` 表示平台理论上能跑，`enabled` 表示当前 rollout 真正放开。`ACCOUNT_GROUP` 是严格必填项，并会选中一份账号组配置。运行身份不完整时，服务会直接失败，不再静默回退。
 
 注意：
 
 - 只有在 `ENABLE_GITHUB_ENV_SYNC=true` 时，这个 workflow 才会严格校验并执行同步。没打开时会直接跳过。打开后，它会通过 `scripts/print_strategy_profile_status.py --json` 动态解析目标策略需要的 snapshot/config 输入，不再维护硬编码策略名列表。
+- slot 部署应配置 `CLOUD_RUN_SERVICES`，不要继续依赖旧的 `CLOUD_RUN_SERVICE`。在 GitHub runtime 变量能准确描述每个 slot 前，不要打开全量同步；否则一份共享的 `RUNTIME_TARGET_JSON` 会覆盖各 slot 自己的运行身份。
 - 这里说的“共享配置”仍然只针对 **IBKR 这一组系统**。`TELEGRAM_TOKEN` 和 `TELEGRAM_TOKEN_SECRET_NAME` 都还是这个仓库自己的配置，不建议提升成所有 quant 共用的全局配置。危机告警如果确实跨平台共用同一套收件人和发送方，可以用 GitHub Organization Variables/Secrets 管理 `CRISIS_ALERT_CHANNELS`、`CRISIS_ALERT_EMAIL_*` 和 `CRISIS_ALERT_PUSH_*`。
 - 如果设置了 `IB_ACCOUNT_GROUP_CONFIG_SECRET_NAME`，Cloud Run 运行时还需要有对应 Secret 的访问权限。
 - GitHub 现在通过 OIDC + Workload Identity Federation 登录 Google Cloud，这个 workflow 不再需要 `GCP_SA_KEY`。
