📋 Decision Context

Question:

How to fix authenticated user browser tab crash when navigating to a space URL that doesn't belong to them (e.g., /space/some-random-space/dashboard)?

Task: Fix browser tab crash when authenticated user visits wrong space URL

🎯 Decision Made

Chosen:

Added a synchronous FAST PATH at the top of spaceGuard (before any async operations) that checks the URL slug against the already-loaded space. If slug matches → allow immediately. If slug is unknown → redirect to current space (dev mode) or /space-not-found (subdomain mode). This completely bypasses the 600+ lines of expensive async operations (lazy import of @libs-ui/auth-ui, initializeSpace HTTP calls, loadUniverses) that were crashing the browser tab.

Options Considered:

1. FAST PATH synchronous check before async operations
2. Wrap async operations in try/catch with timeout
3. Add URL validation middleware before guard runs
4. Debounce/throttle guard execution

💭 Reasoning

The space.guard.ts is 600+ lines with heavy async operations: (1) lazy import('@libs-ui/auth-ui') which in Vite dev mode loads hundreds of modules, (2) spaceService.initializeSpace() which makes HTTP calls to backend + loads universes. When a user navigated to a non-existent space slug, ALL of these expensive operations ran before discovering the slug was invalid. Combined with Vite's per-module HTTP requests and the loading orchestrator's navigation overlay, this caused the browser renderer process to crash (tab navigated to chrome://new-tab-page/). The fix is a synchronous check BEFORE any async work: if a space is already loaded, compare the URL slug against it immediately. No network calls, no lazy imports, no crash risk.
