From ba3577c7f94e2313485c41cfee7adb3e7aff0a19 Mon Sep 17 00:00:00 2001 From: James Arthur Date: Tue, 20 Jan 2026 22:33:50 +0000 Subject: [PATCH 01/27] feat(stream): add internal/stream package with shared message types MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Create the foundation for durable stream communication between wisp-sprite and clients. Defines event types (session, task, claude_event, input_request), command types (kill, background, input_response), and acknowledgment messages. Includes: - types.go: Event struct with JSON serialization, typed data accessors, command and ack creation helpers - types_test.go: Comprehensive unit tests for serialization round-trips 🤖 Generated

Features: - Append() writes events with assigned sequence numbers and fsync - Read(fromSeq) reads events from a given sequence number - Subscribe() provides polling-based event streaming via channels - Thread-safe with mutex protection for concurrent access - Handles malformed lines gracefully (skips them) - Creates directories as needed 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 --- internal/stream/filestore.go | 273 ++++++++++++ internal/stream/filestore_test.go | 697 ++++++++++++++++++++++++++++++ 2 files changed, 970 insertions(+) create mode 100644 internal/stream/filestore.go create mode 100644 internal/stream/filestore_test.go diff --git a/internal/stream/filestore.go b/internal/stream/filestore.go new file mode 100644 index 0000000..840643e --- /dev/null +++ b/internal/stream/filestore.go @@ -0,0 +1,273 @@ +// Package stream provides shared types and utilities for durable stream +// communication between wisp-sprite (on the Sprite VM) and clients (TUI/web). +package stream + +import ( + "bufio" + "context" + "encoding/json" + "fmt" + "os" + "path/filepath" + "sync" + "time" +) + +// FileStore provides file-based persistent storage for stream events. +// It is designed to run on the Sprite VM and provides durability across +// disconnections.

03/27] feat(stream): add StreamClient for HTTP-based stream consumption MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add StreamClient that connects to the stream server on a Sprite: - Connect() tests connection to server via /state endpoint - Subscribe() returns channel of events via SSE with auto-reconnect - SendCommand() POSTs commands and returns acknowledgments - GetState() fetches current state snapshot - Automatic reconnection with configurable retry interval and max attempts - Support for auth tokens and custom HTTP clients Includes comprehensive tests with mock HTTP server. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 --- internal/stream/client.go | 402 +++++++++++++++++

512366d9ff9825cad00db93e08794ab7627f8178 Mon Sep 17 00:00:00 2001 From: James Arthur Date: Tue, 20 Jan 2026 22:49:01 +0000 Subject: [PATCH 04/27] feat(spriteloop): add core loop logic for Sprite VM execution MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Create internal/spriteloop package with iteration loop logic designed to run directly on Sprite VMs. This package extracts and adapts the core loop from internal/loop but for local execution: - loop.go: Main iteration loop with exit conditions (done, blocked, max iterations, max duration, stuck detection, user commands) - executor.go: ClaudeExecutor interface for Claude command execution with LocalExecutor implementation and MockExecutor for testing - doc.go: Package documentation Key features: - Direct file access (no SSH) for state files in /var/local/wisp/session/ - FileStore integration for publishing events to durable stream - Command handling (kill, background, input_response) via channel - Stuck detection based on progress history - Comprehensive test coverage 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 ---

Claude stream-json output parsing MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add types and functions for parsing Claude Code stream-json output. This enables monitoring and extracting information from Claude's execution during the iteration loop: - StreamEvent types for system/init, assistant, user, and result events - ContentBlock parsing for text, tool_use, and tool_result content - StreamState for tracking accumulated progress (tool calls, turns, cost) - StreamParser for convenient line-by-line processing with callbacks - ToolInput parsing for extracting common tool parameters The parsing separates Claude output format knowledge from loop/executor logic, enabling clients to understand execution progress in real-time. 🤖 Generated

036ed13f0f2a2b01b005ddca60766eabdd340c65 Mon Sep 17 00:00:00 2001 From: James Arthur Date: Tue, 20 Jan 2026 22:59:19 +0000 Subject: [PATCH 07/27] feat(spriteloop): add HTTP server for stream and commands MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add Server struct that provides HTTP endpoints for communication between TUI/web clients and the Sprite VM: - GET /stream: SSE endpoint for real-time event streaming - POST /command: Receive commands (kill, background, input_response) - GET /state: Current state snapshot with session, tasks, pending input - GET /health: Health check with last sequence number Features: - Bearer token authentication (optional) with query param fallback - Graceful shutdown support - Configurable polling interval - Keepalive SSE comments to prevent connection timeouts - from_seq parameter for catching up on missed events 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By:

James Arthur Date: Tue, 20 Jan 2026 23:18:51 +0000 Subject: [PATCH 13/27] refactor(server): add relay mode for forwarding Sprite events to web clients MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This change adapts internal/server/streams.go to work with the stream client, enabling the web server to act as a relay between the Sprite and web clients. Key changes: - Add NewRelayStreamManager() for creating a manager in relay mode - Add StartRelay()/StopRelay() to manage the event forwarding loop - Add methods to forward commands to Sprite (SendCommandToSprite, etc.) - Update Server config to support SpriteURL and SpriteAuthToken - Update handleInput to forward input responses to Sprite in relay mode - Add conversion functions between stream.* types and server.* types - Add comprehensive tests for relay mode functionality The server now supports two modes: 1. Local mode: Events stored locally (for testing or single-machine setup) 2. Relay mode: Events relayed from remote Sprite via StreamClient 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 --- internal/server/server.go | 51 +++++- internal/server/streams.go | 312 ++++++++++++++++++++++++++++++++ internal/server/streams_test.go | 132 ++++++++++++++ 3 files changed, 491 insertions(+), 4 deletions(-) diff --git a/internal/server/server.go b/internal/server/server.go index 68204f0..466bb91 100644 --- a/internal/server/server.go +++ b/internal/server/server.go @@ -57,9 +57,15 @@ type Config struct { Port int PasswordHash string Assets fs.FS // Optional: static assets filesystem.

b3ed24a2cf9e981bb2f64cffe87e52081fafcfce Mon Sep 17 00:00:00 2001 From: James Arthur Date: Wed, 21 Jan 2026 00:13:42 +0000 Subject: [PATCH 14/27] refactor(loop): simplify to orchestration-only role MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The loop package now coordinates with wisp-sprite rather than running iterations directly. The iteration logic has been moved to spriteloop. Changes: - Remove runIteration, buildClaudeArgs, parseStreamJSON, streamOutput - Remove duration/budget/stuck checking (now in spriteloop) - Remove handleNeedsInput, updateTUIState (now via stream events) - Add stream client integration for wisp-sprite communication - Add handlers for stream events (session, task, claude, input_request) - Add handlers for TUI actions (kill, background, input) - Update tests for simplified interface 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 --- internal/loop/loop.go | 961 ++++++------------- internal/loop/loop_test.go | 1842 ++++-------------------------------- 2 files changed, 495 insertions(+), 2308 deletions(-) diff --git a/internal/loop/loop.go b/internal/loop/loop.go index 41222a8..25fa586 100644 --- a/internal/loop/loop.go +++ b/internal/loop/loop.go @@ -1,20 +1,16 @@ package loop import ( -

This brings several benefits: - Uses battle-tested durable-streams file storage with proper metadata tracking via bbolt - Adds long-poll notification for efficient subscriber updates - Maintains the same public API (Append, Read, Subscribe, LastSeq, Close, Path) - Idempotent Close() operation prevents double-close panics The implementation stores events in a .stream-data subdirectory using durable-streams' internal segment format, while maintaining the same sequence-numbered Event struct interface for consumers. Test updates: - Remove tests that relied on direct file system access to internal storage format (durable-streams manages its own format) - Update persistence test to verify through API rather than reading raw files - Update directory creation test to verify data is stored 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 --- internal/stream/filestore.go | 244 ++++++++++++++++++------------ internal/stream/filestore_test.go | 88 +++-------- 2 files changed, 166 insertions(+), 166 deletions(-) diff --git a/internal/stream/filestore.go b/internal/stream/filestore.go index 840643e..1fad47c 100644 --- a/internal/stream/filestore.go +++ b/internal/stream/filestore.go @@ -3,7 +3,6 @@ package stream import ( - "bufio" "context" "encoding/json" "fmt" @@ -11,82 +10,138 @@ import ( "path/filepath" "sync" "time" + + "github.com/durable-streams/durable-streams/packages/caddy-plugin/store" ) +// streamPath is the internal path used for the durable-streams store. +const streamPath = "/wisp/events" + // FileStore provides file-based persistent storage for stream events. -// It is designed to run on the Sprite VM and provides durability across +// It wraps the durable-streams FileStore to provide durability across // disconnections.

Key changes: - Headers now contain Operation (insert/update/delete), TxID, and Timestamp - NewEvent takes 3 args (msgType, key, value) instead of 2 - Separated InputRequest and InputResponse into distinct event types - InputResponse is now its own event type, not a command type - Added typed event creators: NewSessionEvent, NewTaskEvent, etc. - Updated all consumers: spriteloop, server, tui, loop packages This aligns the Go types with the frontend @durable-streams/state schema for seamless sync. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 --- internal/loop/loop.go | 12 +- internal/server/streams.go | 39 +++- internal/server/streams_test.go | 11 +- internal/spriteloop/commands.go | 115 +++++----- internal/spriteloop/commands_test.go | 55 ++--- internal/spriteloop/loop.go | 131 +++++++----- internal/spriteloop/loop_test.go | 25 +-- internal/spriteloop/server.go | 6 +- internal/spriteloop/server_test.go | 19 +- internal/stream/client.go | 55 ++++- internal/stream/client_test.go | 40 ++-- internal/stream/filestore_test.go | 54 ++--- internal/stream/types.go | 279 +++++++++++++++++-------- internal/stream/types_test.go | 300 ++++++++++++++++++++------- internal/tui/stream.go | 3 +- internal/tui/stream_test.go | 38 ++-- internal/tui/tui.go | 35 ++-- 17 files changed, 781 insertions(+), 436 deletions(-) diff --git a/internal/loop/loop.go b/internal/loop/loop.go index 25fa586..4587f36 100644 --- a/internal/loop/loop.go +++ b/internal/loop/loop.go @@ -434,11 +434,7 @@ func (l *Loop) handleInputRequestEvent(ctx context.Context, event *stream.Event) return Result{Reason: ExitReasonUnknown} } -

This change makes the client compatible with any durable-streams server. Key changes: - Connect() now uses HEAD request to check stream existence - Subscribe() uses GET /{path}?offset=X&live=sse for SSE streaming - SendCommand/SendInputResponse use POST /{path} to append events - GetState() reads all events and reconstructs state snapshot - Track offsets (durable-streams format) alongside synthetic seq numbers - Parse durable-streams SSE format (event: data/control events) The client maintains backward compatibility with consumers (TUI/server) by keeping the same interface, while internally using durable-streams protocol for communication. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 --- internal/stream/client.go | 434 ++++++++++++++++++++++++++++----- internal/stream/client_test.go | 258 ++++++++++++++------ 2 files changed, 556 insertions(+), 136 deletions(-) diff --git a/internal/stream/client.go b/internal/stream/client.go index ef4d1f8..9357755 100644 --- a/internal/stream/client.go +++ b/internal/stream/client.go @@ -1,5 +1,8 @@ // Package stream provides shared types and utilities for durable stream // communication between wisp-sprite (on the Sprite VM) and clients (TUI/web). +// +// This client implements the durable-streams HTTP protocol for communicating +// with a durable-streams server.

Changes: - Add TxID field to InputResponse for transaction confirmation - Add await.go with AwaitInputResponse and InputResponseWatcher helpers - Update handleNeedsInput to use stream-based event watching - Remove in-memory pendingInputs map from CommandProcessor - Update server.go to use StreamManager for input state tracking - Add IsInputResponded, GetInputResponse methods to StreamManager - Update HandleInputResponse to return bool (first-response-wins) The new approach: 1. Input requests are published as durable events to the stream 2. Clients append input_response events to the stream 3. The loop watches for matching input_response events 4. Transaction confirmation via TxID header pattern This eliminates the 100ms polling interval and provides: - Event-driven responsiveness - Durable state that survives disconnections - First-response-wins conflict resolution via stream 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 --- internal/server/server.go | 87 ++++++---- internal/server/server_test.go | 32 ++-- internal/server/streams.go | 48 +++++- internal/spriteloop/commands.go | 94 +++++++---- internal/spriteloop/commands_test.go | 33 ++-- internal/spriteloop/loop.go | 44 ++++- internal/stream/await.go | 160 ++++++++++++++++++ internal/stream/await_test.go | 235 +++++++++++++++++++++++++++ internal/stream/types.go | 4 + 9 files changed, 624 insertions(+), 113 deletions(-) create mode 100644 internal/stream/await.go create mode 100644 internal/stream/await_test.go diff --git a/internal/server/server.go b/internal/server/server.go index 466bb91..d65862a 100644 --- a/internal/server/server.go +++ b/internal/server/server.go @@ -575,40 +575,35 @@ func (s *Server) handleInput(w http.ResponseWriter, r *http.Request) { return } -

This extracts ~80% duplicated code from start.go and resume.go. Changes: - Add SpriteSetupMode enum (Start/Resume) for mode-specific behavior - Add SpriteSetupConfig struct with all setup parameters - Move HandleServerPassword to sprite.go (shared between start/resume) - Move checkoutBranch helper to sprite.go - Update start.go, resume.go, review.go, update.go to use new shared code - Update tests to use HandleServerPassword instead of handleResumeServerPassword Net reduction of ~68 lines while consolidating duplicated logic. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 ---

+0000 Subject: [PATCH 25/27] fix(server): replace CORS Allow-Origin: * with configurable origins MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Replace wildcard CORS origin with a secure configurable approach: - Add CORSOrigins field to ServerConfig and server.Config - Default to localhost:3000/5173 and 127.0.0.1:3000/5173 for dev - Implement origin validation with fast map lookup - Add CORS preflight (OPTIONS) request handling - Reject cross-origin requests from non-allowed origins - Add withCORS middleware for consistent CORS handling - Include comprehensive tests for CORS behavior Production deployments can configure allowed origins via config. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5

Subject: [PATCH 26/27] fix(server): add rate limiting to /auth endpoint MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add sliding window rate limiting to the authentication endpoint to prevent brute force attacks: - 5 requests per minute per IP (configurable) - Exponential backoff blocking after 10 failed attempts - Block duration doubles with each consecutive block (capped at 24h) - X-Forwarded-For support for reverse proxy scenarios - Logged rate-limited requests for security monitoring - Retry-After header in 429 responses The rate limiter tracks both rate limits (sliding window) and failure counts separately.

charset=UTF-8 Content-Transfer-Encoding: 8bit Add internal/logging package with structured logging support: - Logger with debug/info/warn/error levels - Context fields via With() and WithFields() methods - Key-value logging for structured output - Default minimum level set to warn Update error handling throughout the codebase: - spriteloop/loop.go: Log publish function failures with context - server/streams.go: Log relay loop and event handler errors - loop/loop.go: Log TUI action and broadcast failures - tui/stream.go: Log action handling failures - CLI commands (done, stop, sprite, resume, review, update, start, abandon): Add structured logging alongside user-facing warnings The logging adds visibility into non-fatal errors that were previously silently swallowed, improving debugging and monitoring capabilities while maintaining user-facing fmt.Printf warnings for interactive use. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 --- internal/cli/abandon.go | 3 + internal/cli/done.go | 6 + internal/cli/resume.go | 4 + internal/cli/review.go | 3 + internal/cli/sprite.go | 8 ++ internal/cli/start.go | 41 +++--- internal/cli/stop.go | 5 + internal/cli/update.go | 4 + internal/logging/logger.go | 229 ++++++++++++++++++++++++++++++++ internal/logging/logger_test.go | 216 ++++++++++++++++++++++++++++++ internal/loop/loop.go | 39 ++++-- internal/server/streams.go | 29 +++- internal/spriteloop/loop.go | 52 ++++++-- internal/tui/stream.go | 19 ++- 14 files changed, 605 insertions(+), 53 deletions(-) create mode 100644 internal/logging/logger.go create mode 100644 internal/logging/logger_test.go diff --git a/internal/cli/abandon.go b/internal/cli/abandon.go index e97259f..3c95466 100644 --- a/internal/cli/abandon.go +++ b/internal/cli/abandon.go @@ -7,6 +7,7 @@ import ( "github.com/spf13/cobra" "github.com/thruflo/wisp/internal/config" + "github.com/thruflo/wisp/internal/logging" "github.com/thruflo/wisp/internal/sprite" "github.com/thruflo/wisp/internal/state" ) @@ -125,6 +126,7 @@ func runAbandonAll(ctx context.Context, cwd string, store *state.Store) error { fmt.Printf("\nAbandoning session '%s'...\n", session.Branch) if err := abandonSession(ctx, cwd, store, session);
