fix(graph): preserve completion-ready runs on lead settlement - #1127
Merged
Conversation
Avoid cancelling Graph runs whose completion gates already passed when the owning Lead turn settles incidentally; resume finalization instead of force-cancel. Co-authored-by: Cursor <cursoragent@cursor.com>

* feat(explore_agent): enhance tool descriptions and establish exploration as the first step for repository investigations * feat: implement thread snapshot caching and state management - Added a thread snapshot cache to optimize thread state retrieval and management. - Introduced functions to snapshot thread projections, retrieve snapshots, and invalidate them. - Enhanced thread actions to utilize the new snapshot cache for improved performance. - Updated chat store types to include a loading state for threads. - Added tests for thread snapshot caching behavior and limits. - Introduced new API endpoints for retrieving thread states. - Updated existing actions and tests to accommodate the new snapshot caching mechanism. * feat(chromium-cookies): add cookie reading and decryption functionality for Chromium browsers * feat: add tool cancellation functionality - Implemented `cancelToolCall` function in `turns.ts` to handle tool call cancellations. - Created `ToolCancellationService` to manage cancellation requests and state. - Added new endpoint for tool cancellation in `kun-endpoints.ts`. - Updated IPC schemas to include tool cancellation. - Enhanced the chat store to support tool cancellation actions. - Added UI components for cancelling tool calls in the chat interface. - Updated localization files to include new strings for tool cancellation. - Added tests for `ToolCancellationService` to ensure correct behavior. - Modified state management to handle turn abortion and tool cancellation. * refactor: simplify telemetry pressure management and improve model request handling - Removed the `hydratePromptPressureIfCold` method from `LoopTelemetry` to streamline prompt pressure management. - Updated `HistoryCompactionService` to eliminate unnecessary telemetry calls. - Adjusted `effectiveOutputBudgetTokens` to ensure output capabilities are bounded by context capacity. - Enhanced tests to reflect changes in telemetry and model request behavior. - Modified UI components for better media preview handling and adjusted styles for consistency. - Updated localization strings for clarity in token usage descriptions. - Added new tests to ensure proper handling of compaction markers and model provider presets. * feat: add timing metrics for usage tracking - Implemented timing aggregation for thread-cumulative average time-to-first-token (TTFT) and tokens-per-second (TPS) in UsageCounter. - Updated UsageCounter to handle missing timing fields as null instead of zero. - Enhanced tests for UsageCounter to validate timing aggregation across threads and reset behavior. - Introduced new fields in CoreUsageSnapshotJson for request timing metrics and averages. - Updated mapping functions to pass through timing metrics to the UI. - Added formatting functions for displaying TTFT and TPS in a user-friendly manner. - Enhanced chat projection reducer to manage per-turn timing metrics keyed by turnId. - Updated initial state and types to accommodate new timing metrics. - Added localization strings for new timing metrics in multiple languages. * feat: enhance speech-to-text settings with credential readiness checks and improve provider API key handling * feat: enhance model handling by preventing empty primary model from overwriting current settings * fix(office): soft-fail WPS schema validate on intake Strict OpenXML validation rejected WPS etCustomData attributes on xlsx autoFilter, so drag-drop fell back to a local tool reference. Treat Schema/undeclared vendor attrs as warnings and continue text extraction; keep edit-path validation strict. Fixes #1122 Co-authored-by: Cursor <cursoragent@cursor.com> * fix(providers): keep Token Plan catalog across registry races Fetch/import could stage models before the shared connection existed, so catalog commit failed and SSE projection dropped the local provider back to presets. Connect-then-patch missing connections, retain pending local catalogs during projection, and skip AppSettings writes while a catalog drain is in flight. Fixes #1117 Co-authored-by: Cursor <cursoragent@cursor.com> * fix(runtime): recover shared Kun when discovery PID is dead Detached shared runtimes could leave a stale resolvedConnection after the process exited, so watchdog treated the host as unresponsive and waited through repeated health failures. Clear dead discovery PIDs from the adapter cache and re-check isChildRunning after health probes so recovery takes the missing/ensure path. Fixes #1116 Co-authored-by: Cursor <cursoragent@cursor.com> * feat: implement preserveRedactedProviderCredentials function and add tests for credential preservation * feat: add in-place update handling and cleanup for automatic updates * fix(models-dev-catalog): add MiniMax OpenAI-compatible /v1 endpoint aliases (#1126) Recognize api.minimax.io/v1 and api.minimaxi.com/v1 for regular and Token Plan profiles alongside the existing Anthropic endpoints. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(graph): preserve completion-ready runs on lead settlement (#1127) Avoid cancelling Graph runs whose completion gates already passed when the owning Lead turn settles incidentally; resume finalization instead of force-cancel. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(graph): add thread ownership gate and independent SSE observer (#1128) Keep the 5s durable snapshot fallback, but bind Graph projection atomically per thread and project SSE through an owner-scoped observer so Lead settlement and thread switches cannot paint stale Graph state. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(scripts): ensure proper execution of .cmd scripts on Windows by using cmd.exe shell * fix: normalize Codex responses URL and update related endpoint handling * fix: enhance explore_agent tool provider with dynamic advertising based on Lab settings * fix(cursor): re-expose Kun-exclusive tools and exclude overlapping Cursor built-ins * feat: add explore functionality with new components and tests - Implemented explore-card-copy and explore-peek-summary components for handling explore tasks. - Added utility functions to determine tool types and resolve task titles. - Enhanced message-timeline-process to recognize explore_agent as a subagent. - Updated message-timeline-empty to differentiate between explore and subagent sessions. - Created comprehensive tests for new functionalities to ensure reliability. - Updated localization files to include new strings for explore processes and UI elements. * feat: implement ExplorePeekBody component and related tests; enhance SubagentCallCard with conclusion handling * feat: add explore_agent tool with read-only access; update related tests and documentation * feat: enhance OpenCode Go cookie handling and diagnostics - Introduced support for additional Chromium browsers (Chrome Beta, Chrome Canary, Edge Beta, Edge Canary, Brave Beta, Brave Nightly) in cookie retrieval. - Added a non-sensitive diagnosis type for cookie read operations to distinguish between success, not found, and decryption failures. - Improved cookie header filtering to handle manual Cookie headers and environment variables. - Implemented caching for OpenCode Go cookies with clear and persist functionality. - Enhanced error handling to provide specific messages for Keychain access issues and missing credentials. - Updated tests to cover new cookie handling scenarios and ensure proper functionality across different platforms. * feat: enhance explore_agent handling in tool dispatch policy and message timeline * feat: release v0.2.37 with enhancements to explore_agent, Agent Graph stability, and runtime capabilities - Introduced read-only explore_agent for parallel investigations and improved session presentation. - Enhanced Agent Graph with thread ownership controls and independent SSE observers for better concurrency. - Updated Provider credential handling and model directory stability during concurrent updates. - Added tool cancellation feature and improved usage tracking metrics. - Implemented automatic updates and cleanup for a smoother upgrade process. - Ensured compatibility for Windows script execution and refined document import validation. --------- Co-authored-by: Cursor <cursoragent@cursor.com>
