Add layered channel architecture with Akka.Streams session API#14
Merged
Conversation
Split the channel abstraction into a layered architecture: - Netclaw.Actors exposes SessionPipeline (DI service) that creates MaterializedSession instances with typed Akka.Streams: - Sink<ChannelInput> for input (channel connects its own Source) - Source<SessionOutput> for output (channel connects its own Sink) - SharedKillSwitch for coordinated teardown via IAsyncDisposable - New Netclaw.Channels project contains IChannel interface, ChannelHealth, and ChannelHealthStatus (moved from Netclaw.Actors.Channels) - ChannelInput supports multi-modal content via IReadOnlyList<AIContent> from Microsoft.Extensions.AI.Abstractions - ConsoleChannel and HeadlessChannel rewritten to use stream API - no more subscriber actors, channels compose streams directly - SessionJoined now extends SessionOutput for proper stream typing - MessageSource added to SendUserMessage ([ProtoIgnore]) for ACL/audit
- Mark shell, file, and source-generated tool schema tasks as complete - Defer web search/fetch tools (not needed for minimal viable concept) - Add agent gateway architecture research notes

Update PRDs (001, 004, 009), SPEC-011, and IMPLEMENTATION_PLAN to reflect the OpenClaw-pattern architecture: persistent daemon (Netclaw.Daemon) with thin CLI/TUI clients (Netclaw.Cli) connecting via SignalR. Key changes: - Two binaries: daemon owns Akka/persistence/tools, CLI is lightweight - TUI chat becomes pure thin client rendering SessionOutput over SignalR - CLI commands categorized as offline vs daemon-required - Daemon management commands: start/stop/status/install/uninstall - systemd user service registration (no sudo) - New implementation tasks 1.26-1.31 for the split - Tasks 1.10-1.12 marked as done (PRs #14, #16, #17)

* Revise architecture to daemon + thin client split Update PRDs (001, 004, 009), SPEC-011, and IMPLEMENTATION_PLAN to reflect the OpenClaw-pattern architecture: persistent daemon (Netclaw.Daemon) with thin CLI/TUI clients (Netclaw.Cli) connecting via SignalR. Key changes: - Two binaries: daemon owns Akka/persistence/tools, CLI is lightweight - TUI chat becomes pure thin client rendering SessionOutput over SignalR - CLI commands categorized as offline vs daemon-required - Daemon management commands: start/stop/status/install/uninstall - systemd user service registration (no sudo) - New implementation tasks 1.26-1.31 for the split - Tasks 1.10-1.12 marked as done (PRs #14, #16, #17) * Split Netclaw.App into Netclaw.Daemon and Netclaw.Cli Structural split following the daemon + thin client pattern: - Netclaw.Daemon (netclawd): Web SDK, actor system, SignalR hub, config watcher, health endpoint - Netclaw.Cli (netclaw): CLI routing (chat, -p, init, doctor, daemon stub, config stub), TUI, headless channel Shared types moved to library projects: - Config POCOs (ProviderEntry, ModelSelection, ModelReference) → Netclaw.Configuration - SessionOutputDto → Netclaw.Actors.Protocol CLI temporarily keeps full Akka stack in-process with transitional copies of ChatClientFactory/NetclawChatClientProvider. Task 1.28 refactors to SignalR client and removes Akka dependencies. * Wire SessionHub to SessionPipeline via SessionRegistry Replace the stub SessionHub with a functional implementation that creates sessions, accepts messages, and streams output back to SignalR callers. SessionRegistry (singleton) owns session state and uses IHubContext to push output from Akka.Streams callbacks without requiring a hub instance. * Add daemon management commands (start, stop, status, install, uninstall) DaemonManager handles the full lifecycle: binary discovery, detached process spawning with PID file tracking, graceful SIGTERM shutdown on Linux/macOS, and systemd user service registration. Windows service support tracked in #21. * Fix review issues and update README for daemon architecture Review fixes: - CLI port conflict: use port 0 (random) for transitional in-process mode - SessionHub: call base.OnDisconnectedAsync for framework cleanup - SessionRegistry: log output delivery errors instead of swallowing, guard against duplicate CreateSession per connection, check OfferAsync result for queue failures - DaemonManager: don't redirect stdio (prevents SIGPIPE / pipe deadlock), validate process name before SIGTERM to prevent PID recycling kills, check kill() return value, proper DateTimeOffset for uptime calc - Eliminate duplicate NetclawPaths instances in both Program.cs files README updated to reflect daemon + thin client architecture with CLI reference documentation. * Harden daemon session ownership and PID handling Enforce connection-scoped SignalR sessions with typed IDs, preserve sessions for reconnect, and tighten daemon PID/process validation for safer lifecycle commands. Add targeted tests and daemon PID file ownership to keep status/stop behavior reliable.

Summary
SessionPipeline(DI service) that createsMaterializedSessioninstances with typed Akka.Streams:Sink<ChannelInput>for input andSource<SessionOutput>for output. All actor internals (JoinSession, subscriber refs, message routing) are hidden behind the stream API.Netclaw.Channelsproject containsIChannelinterface,ChannelHealth, andChannelHealthStatus(moved fromNetclaw.Actors.Channels), establishing the layered split between general-purpose LLM runtime and Netclaw-specific channel abstractions.ChannelInputsupports multi-modal content viaIReadOnlyList<AIContent>from Microsoft.Extensions.AI.Abstractions.SessionJoinednow extendsSessionOutputfor proper stream typing.MessageSourceadded toSendUserMessage([ProtoIgnore]) for ACL/audit metadata.Test plan
