Feat/improved logging

[TheodoreSpeaks]

Summary

We need additional observability into our system, even for successful calls.
Add additional logs for the /execute endpoint with metadata for user id, workflow id, workspace id, execution id. Reverted change to upgrade mothership chat logs to error.

I upgraded our logging system to INFO, so all logs should start showing up.

New formatting:

  [2026-03-28T14:32:01.500Z] [DEBUG] [ExecutionLogger] {workflowId=wf-9f3e workspaceId=ws-7720 executionId=exec-88f2} Starting workflow
   execution
  [2026-03-28T14:32:01.512Z] [DEBUG] [ExecutionLogger] {workflowId=wf-9f3e workspaceId=ws-7720 executionId=exec-88f2} Created workflow
  log {"logId":"log-ab12"}
  [2026-03-28T14:32:02.200Z] [DEBUG] [ExecutionLogger] {executionId=exec-88f2} Completing workflow execution {"isResume":false}

PR Summary

Medium Risk
Broad logging changes across workflow execution and copilot/orchestrator paths could increase log volume and affect alerting/performance, but do not change core execution behavior.

Overview
Improves observability by introducing Logger.withMetadata() in @sim/logger and updating log formatting to automatically append key/value metadata to every line.

Refactors workflow execution (/api/workflows/[id]/execute and executor engine/block execution) to use request/execution-scoped loggers with consistent metadata (requestId, workflowId, workspaceId, userId, executionId) and cleans up many log messages.

Downgrades many copilot/chat/orchestrator lifecycle logs from error to info (including stream resume and tool execution) so successful flows are visible without being flagged as errors.

Greptile Summary

This PR delivers two main changes under a single branch: (1) structured logging improvements for the /execute endpoint and copilot routes, and (2) a set of UI enhancements to the sidebar, markdown file viewer, and plus-menu dropdown.

Logging changes:

• Adds a withMetadata() method to the core Logger class, enabling child loggers that automatically prepend key-value context (workflowId, workspaceId, userId, executionId) to every log line without repeating it in every call site.
• Migrates the /execute route from ad-hoc [requestId] string prefixes to a structured reqLogger / asyncLogger built via withMetadata(), matching the new format shown in the PR description.
• Reverts a previous mistake where informational copilot/mothership chat events were logged at ERROR level — all corrected back to INFO.
• Good test coverage added for withMetadata (inheritance, merge, override, undefined filtering).

UI changes:

• Interactive checkbox toggling in the Markdown file preview, using a render-phase counter ref to track checkbox indices across ReactMarkdown renders.
• PlusMenuDropdown refactored to open at an arbitrary viewport anchor (e.g. the @ caret position in the textarea), using a virtual zero-size fixed trigger element.
• Sidebar improvements: keyboard shortcuts for new workflow/task (Mod+Shift+P / Mod+Shift+K), international keyboard layout fix via codeToKey(), sidebar expand via keyboard, and a search-modal centering fix that accounts for sidebar width.

Notable findings:

• The production log level default remains ERROR; the new INFO-level execute route logs require LOG_LEVEL=INFO to be set in the environment to take effect.
• reqLogger is updated twice with userId in handleExecutePost — once from auth.userId and once from actorUserId — which can produce inconsistent context in logs for workspace API key requests.

Confidence Score: 5/5

Safe to merge; all remaining findings are P2 style/informational suggestions with no runtime impact

The core logging feature is well-implemented and thoroughly tested. Copilot route fixes are straightforward level downgrades. UI changes are self-contained. No P0/P1 issues found — both flagged items are P2 observations that don't block correct operation.

No files require special attention; the two P2 notes in packages/logger/src/index.ts and apps/sim/app/api/workflows/[id]/execute/route.ts are informational only

Important Files Changed

Filename	Overview
packages/logger/src/index.ts	Adds withMetadata() to the Logger class, returning a child logger that prepends key-value pairs to every log line; production default log level remains ERROR (override via LOG_LEVEL env var)
packages/logger/src/index.test.ts	Adds thorough unit tests for the new withMetadata feature, covering inheritance, merging, override, and undefined-value filtering
apps/sim/app/api/workflows/[id]/execute/route.ts	Replaces manual [requestId] string prefixes with structured reqLogger / asyncLogger built via withMetadata; executionId, userId, workspaceId, and workflowId are all carried in metadata
apps/sim/lib/logs/execution/logger.ts	Adopts withMetadata for executionId context; enriches execLog with workflowId/workspaceId after DB lookup inside completeExecution
apps/sim/app/workspace/[workspaceId]/files/components/file-viewer/preview-panel.tsx	Adds interactive checkbox support for Markdown previews; uses a render-phase counter ref pattern to track checkbox indices across ReactMarkdown renders
apps/sim/app/workspace/[workspaceId]/home/components/user-input/components/plus-menu-dropdown.tsx	Refactors PlusMenuDropdown to position itself at an arbitrary viewport anchor (e.g. caret position); separates the trigger button from the DropdownMenu using a zero-size virtual anchor div
apps/sim/app/workspace/[workspaceId]/w/components/sidebar/sidebar.tsx	Large sidebar refactor: adds keyboard shortcuts (Mod+Shift+P/K) for adding workflows/tasks, sidebar expand via keyboard, collapsed-edge click handler, and search modal centering fix for sidebar offset
