SAM Recent Changes
For the latest changes, also check git log --oneline -20.
- session-visibility: VM Agent enriches session responses with live
hostStatus and viewerCount; shared AgentHostStatus type; new listAgentSessionsLive() browser API; enhanced status colors in workspace UI
- devcontainer-runtime-user-consistency: VM Agent resolves effective devcontainer execution user when
CONTAINER_USER is unset; detection order: devcontainer read-configuration > devcontainer.metadata label > docker exec id -un fallback; per-workspace ContainerUser stored in runtime
- workspace-runtime-identity: VM Agent derives host workspace identity from canonical
workspaceId; strict workspace label matching prevents cross-workspace routing
- sam-workspace-env: SAM platform metadata injected as env vars into devcontainers during bootstrap (
SAM_WORKSPACE_ID, SAM_NODE_ID, SAM_WORKSPACE_URL, SAM_API_URL, SAM_REPOSITORY, SAM_BRANCH)
- worktree-context: Deep git worktree integration across VM agent, API, shared types, terminal, and workspace UI; worktree-aware terminal/chat session creation;
WorktreeSelector UI
- node-system-info: VM Agent sysinfo package collects metrics from Linux procfs and Docker CLI; two-tier collection (quick for heartbeat, full for
/system-info endpoint); Node detail page redesigned with composed section components
- devcontainer-named-volumes: Replaced bind-mount storage with named Docker volumes (
sam-ws-<workspaceId>); eliminated permission normalization
- command-palette-search: Enhanced command palette with fuzzy file search and tab switching; camelCase-aware fuzzy matching
- tab-reorder-rename: Unified tab ordering, rename, and drag-and-drop reordering; useTabOrder hook with localStorage persistence
- persistent-agent-sessions: Agent processes survive browser disconnects; SessionHost owns agent lifecycle independently; fan-out message broadcasting; bounded message ring buffer for late-join replay
- workspace-keyboard-shortcuts: VS Code-style keyboard shortcuts; centralized shortcut registry with platform-aware matching
- agent-settings-acp-protocol: Wire agent settings through ACP protocol; all 5 permission modes exposed
- comprehensive-lifecycle-logging: End-to-end ACP/WebSocket lifecycle observability via CF Workers
- vm-agent-error-reporting: Go errorreport package with batching and periodic flushing
- client-error-reporting: Client-side error reporting pipeline with batched sends
- agent-file-ops: ACP ReadTextFile and WriteTextFile handlers via docker exec
- file-browser: File browser with directory listing and syntax-highlighted file viewer
- git-changes-viewer: GitHub PR-style git changes viewer with unified diff
- voice-to-text: Voice input with Workers AI Whisper transcription
- 014-multi-workspace-nodes: First-class Nodes with multi-workspace hosting, async provisioning, workspace recovery
- 013-agent-oauth-support: Dual credential support for Claude Code (API key + OAuth token)
- 012-pty-session-persistence: PTY sessions survive page refresh with ring buffer replay
