 ### Recent Fixes
 
 - **2026-03-27**: WebSearch dashboard cards now manage Exa, Tavily, and Brave API keys inline instead of relying on a separate manual env step. CCS stores those secrets through `global_env`, reflects masked key state in `/api/websearch`, and counts dashboard-managed keys as ready in the WebSearch status flow.
+- **2026-03-27**: **#812** CCS now includes a first-class `ccs docker` command suite for self-hosting the integrated Dashboard + CLIProxy stack. The CLI can stage bundled Docker assets locally or to a remote `--host` over SSH, report compose/supervisor status, stream CCS or CLIProxy logs, and run in-container update flows without relying on ad-hoc deployment scripts.
 - **2026-03-24**: Official Claude Channels now follow Anthropic's actual runtime contract. CCS blocks auto-enable unless Bun is available, Claude Code is verified at v2.1.80+, and `claude.ai` auth is verified; treats `--allow-dangerously-skip-permissions` as an explicit override; keeps Telegram/Discord bot tokens in Claude's shared `~/.claude/channels/` state (or official `*_STATE_DIR` overrides); and upgrades the dashboard/CLI status flow with Bun/version/auth/state-scope guidance, safer token draft retention on refresh failures, and a non-macOS iMessage toggle that can still be turned off when already selected.
 - **2026-03-23**: CLIProxy providers that do not expose an email no longer require a user-supplied nickname on first auth. CCS now derives a stable internal account identifier for Kiro/Copilot-style flows, preserves later rename support, hardens account discovery/registry sync around that identifier, and updates AI Provider CRUD to use stable entry IDs instead of dashboard list indexes.
 - **2026-03-23**: Sensitive dashboard management routes now fail closed to localhost-only access whenever dashboard auth is disabled. Remote access remains available after `ccs config auth setup`, but AI Provider management, CLIProxy auth/status helpers, and other write-capable settings endpoints no longer trust unauthenticated non-loopback requests.
