Summary by CodeRabbit

• New Features
  • Added a reload control to refresh a lab’s repository-backed content. The refreshed content appears after loading completes, while setup and saved progress are preserved.
  • Refreshes use the lab’s approved catalog source and may affect other labs and users sharing that source.
• Bug Fixes
  • The current content remains visible if a refresh fails, and users can retry. Canceled or outdated refreshes won’t replace the displayed content.

Walkthrough

Adds a temporary authenticated repository-resync flow. The backend refreshes a repository and branch selected from the live catalog. The lab drawer then reloads the current page while retaining setup state and saved progress.

Changes

Repository resync

Layer / File(s)	Summary
Serialize and stage source refreshes backend/internal/bundle/cache.go, backend/internal/bundle/cache_test.go	Refreshes for the same source serialize, while refreshes for different branches can proceed independently. Cancellation checks prevent canceled refreshes from publishing or returning success.
Expose targeted refresh through the backend backend/internal/bundle/refresh_coordinator.go, backend/internal/bundle/refresh_coordinator_test.go, backend/internal/handler/handler.go, backend/internal/handler/handler_test.go, backend/cmd/server/main.go	The coordinator refreshes one repository and branch with a ten-minute timeout. The authenticated endpoint selects the source from the catalog and maps refresh outcomes to HTTP statuses. Server configuration connects the handler to the coordinator.
Add the resync API operation frontend/src/api/client.ts, frontend/src/api/__tests__/client.test.ts	The API client validates catalog references, sends the resync request with an optional abort signal, and requires a 204 response.
Refresh and replace the active drawer page frontend/src/InteractiveLabsPage.tsx, frontend/src/InteractiveLabsPage.test.tsx, frontend/src/interactive-labs.css, dev/docs/README.md, dev/docs/administrator-guide.md, dev/docs/architecture.md	The drawer stages refreshed content before replacing the current page. It preserves setup attributes and saved progress, shows failures, and aborts requests when the active context changes. Tests and documentation cover the control and flow.

frontend/src/InteractiveLabsPage.tsx: 1

355-356: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

Assign currentContentRef in an effect, not during render.

Line 356 writes to the ref during every render. React can discard a render without committing it. The isCurrent() check in resync would then compare against a panel that never committed. Line 509 copies currentContentRef.current.panel!, so it can read uncommitted state too. React 17 does not replay renders in non-concurrent mode, so the practical risk today is low. Move the assignment into a useLayoutEffect so the ref only holds committed values.

♻️ Proposed fix

   const currentContentRef = React.useRef({ panel: activePanel, defaultNamespace });
-  currentContentRef.current = { panel: activePanel, defaultNamespace };
+  React.useLayoutEffect(() => {
+    currentContentRef.current = { panel: activePanel, defaultNamespace };
+  });

🪛 React Doctor (0.9.14)

frontend/src/InteractiveLabsPage.tsx

[error] 356-356: This ref is mutated during render. React can replay or discard render work, so the mutation can leak from UI that never commits.

Move ref writes into an event handler or effect. Render must stay pure because React can replay or discard it. The predictable null-guarded lazy initialization pattern remains supported.
