-## Internal Shared Sources
+## Extracted Crates

-The main `ironclaw` crate owns its shared event types and safety layer under `src/common/` and `src/safety/`. The unpublished `ironclaw_common` and `ironclaw_safety` helper crates are internal wrappers around those same source files for workspace-only uses such as fuzzing.
-
-When working inside the main crate, import from the in-crate modules:
- use `crate::common::{AppEvent, ToolDecisionDto, truncate_preview}`
- use `crate::safety::*` (for example `use crate::safety::SafetyLayer`)
-
-The standalone helper crates remain for internal workspace uses such as fuzzing, not as the primary import path for the main crate.
+Safety logic lives in `crates/ironclaw_safety/`. The `src/safety/mod.rs` shim re-exports everything for backward compatibility, but **new code should import from `ironclaw_safety` directly** (e.g. `use ironclaw_safety::SafetyLayer`). When touching a file that still uses `crate::safety::*`, migrate its imports to `ironclaw_safety::*`.

This happens when `end.saturating_sub(1)` in `is_recoverable_tool_call_segment()` steps back into a multi-byte char like emoji. Fix: clamp `pos` to `text.len()` and walk backward to the nearest char boundary before slicing. Add 5 regression tests covering mid-char positions, emoji boundaries, and out-of-bounds pos. Also fix pre-existing clippy `unnecessary_sort_by` warnings in web gateway handlers.

Illia Polosukhin GitHub Claude Opus 4.6	9c5ba43ccd	feat(gateway): add OpenAI Responses API endpoints (#1656 ) * feat(gateway): add OpenAI Responses API endpoints Add POST /v1/responses and GET /v1/responses/{id} to the web gateway, implementing the OpenAI Responses API. Unlike the existing Chat Completions proxy which passes through to the raw LLM, the Responses API routes requests through the full agent loop — giving external clients access to tools, memory, safety, and server-side conversation state via a standard OpenAI-compatible interface. Key design decisions: - Response IDs encode thread UUIDs statelessly (resp_{uuid_simple}) - previous_response_id enables multi-turn conversations - Streaming maps AppEvent variants to Responses API SSE events - Tool approval returns response.failed (no interactive approval flow) - GET endpoint reconstructs ResponseObject from conversation_messages Co-Authored-By: Claude Opus 4.6 (1M context) <[email protected]> * fix(responses-api): address all review feedback on PR #1656 - Decouple response ID from thread ID: encode both a per-call response_uuid and the thread_uuid so each POST produces a unique ID - Reject unsupported fields (instructions, tools, tool_choice, temperature, max_output_tokens, non-default model) with 400 - Add user_id to IncomingMessage metadata for user-scoped SSE events - Add conversation_belongs_to_user() ownership check on GET endpoint - Fix tool call parsing: handle both legacy array and object wrapper format; use call_id/tool_call_id/id key fallback chain - Correlate tool role messages to preceding FunctionCall call_id - Stabilize created_at (capture once in accumulator, reuse everywhere) - Surface error_message via new ResponseObject.error field - Handle streaming tool failures (emit FunctionCallOutput on error) - Remove dead Incomplete status variant - Fix formatting (cargo fmt) Co-Authored-By: Claude Opus 4.6 (1M context) <[email protected]> --------- Co-authored-by: Claude Opus 4.6 (1M context) <[email protected]>	2026-03-27 00:00:25 -07:00

jr42 GitHub Claude Opus 4.6[email protected] <[email protected]>	1d5777824c	fix(mcp): handle 202 Accepted and wire session manager for Streamable HTTP (#1437 ) * fix(mcp): handle 202 Accepted for Streamable HTTP notifications The MCP Streamable HTTP spec requires servers to respond with 202 Accepted (empty body) for JSON-RPC notifications like `notifications/initialized`. The HTTP transport tried to parse this empty body as JSON, which failed and broke the session handshake — subsequent requests like `tools/list` were rejected because the server considered the session uninitialized. Add an early return for 202 responses that produces an empty McpResponse without attempting body parsing. Fixes #1436 Co-Authored-By: Claude Opus 4.6 (1M context) <[email protected]> * fix(mcp): wire session manager into transport for non-OAuth HTTP clients The factory used McpClient::new_with_config().with_session_manager() which only set the session manager on the client, not on the HttpMcpTransport. The transport never captured Mcp-Session-Id from responses, so subsequent requests lacked the header and the server rejected them as uninitialized. Fix by constructing the HttpMcpTransport with the session manager before wrapping it in Arc, matching the pattern already used by new_authenticated(). Co-Authored-By: Claude Opus 4.6 (1M context) <[email protected]> * refactor(mcp): deduplicate factory HTTP path, gate dead-code methods as test-only - Collapse the two identical non-OAuth HTTP branches in `create_client_from_config()` into one (early-return for the authenticated path, fall through for the common case). - Gate `McpClient::new_with_config()` and `McpClient::with_session_manager()` as `#[cfg(test)]` — the factory was their only production caller and no longer uses them. Both methods silently skip wiring the session manager into the transport, which was the root cause of #1436. - Add doc warnings on both methods explaining the footgun.

Pierre LE GUEN GitHub Claude Opus 4.6	adf4e25c8f	fix(extensions): channel-relay auth dead-end, observability, and URL override (#1681 ) * fix(extensions): channel-relay auth dead-end, add observability and relay URL override Fix a bug where clicking Activate on the Slack relay extension produces a dead-end "Authentication required" error with no OAuth URL. The root cause: `auth_channel_relay()` used `is_relay_channel()` to check auth status, but that function returns true as soon as the extension is installed (in-memory set), before OAuth completes. This short-circuits the OAuth flow so the authorization URL is never offered. Changes: 1. Bug fix — `auth_channel_relay()` now uses `has_stored_team_id()` which only checks the persistent settings store for an actual team_id. The extension list `authenticated` field uses the same check so the UI accurately reflects OAuth completion status. 2. Observability — Added debug/warn/info tracing to all channel-relay code paths that were previously silent on failure: - `activate_channel_relay`: team_id retrieval, relay config, signing secret fetch, hot_add, cache operations - `auth_channel_relay`: auth check, OAuth initiation, nonce storage - `extensions_activate_handler`: request entry, auth fallback flow - `slack_relay_oauth_callback_handler`: team_id persistence (was silently ignored with `let _`) - `RelayClient`: initiate_oauth, get_signing_secret, proxy_provider all log URL, status, and errors - `has_stored_team_id`: store read success/failure 3. Per-extension relay URL override — Users can now override the CHANNEL_RELAY_URL via Settings > Extensions > Reconfigure. Stored under `extensions.{name}.relay_url` in settings. Both auth and activate read this override before falling back to the env default. Co-Authored-By: Claude Opus 4.6 (1M context) <[email protected]> * style: cargo fmt Co-Authored-By: Claude Opus 4.6 (1M context) <[email protected]> * fix: address review feedback — clear relay_url override and improve log message 1. Allow clearing the relay_url override: when an optional setup field with a setting_path is submitted empty, delete the stored setting so the system reverts to the env/default value. Previously empty values were silently skipped, making it impossible to undo an override from the UI. 2. Improve the OAuth callback team_id persistence error log to be self-contained without referencing implementation details. Co-Authored-By: Claude Opus 4.6 (1M context) <[email protected]> * style: collapse nested if per clippy::collapsible_if Co-Authored-By: Claude Opus 4.6 (1M context) <[email protected]> * fix: address review feedback — security, scope consistency, and error handling 1. OAuth callback team_id persistence is now fatal: if set_setting fails, the callback returns an error instead of proceeding to activate (which would re-read from the store and fail anyway). 2. effective_relay_url uses owner scope (self.user_id) for reads, matching configure() which writes under the same scope. Prevents multi-user mismatch where an override saved via Reconfigure was invisible during auth/activation. 3. has_stored_team_id uses owner scope for the same reason — the OAuth callback stores team_id under state.owner_id (= self.user_id). 4. Security: effective_relay_url validates the override URL — only http/https without embedded credentials (userinfo) is accepted. This prevents API-key exfiltration if a user points relay_url at an attacker-controlled host. Logs only host portion, not full URL. 5. Fixed effective_relay_url docstring to match behavior (returns Option, callers handle the fallback). 6. get_setup_schema for ChannelRelay now logs a warning on settings store errors instead of silently returning None.
