+## Dashboard Tab State Persistence Fix
+
+Implemented persistent tab state for the Signet dashboard by syncing the active tab to `location.hash`. Previously, refreshing the page would always drop the user back to the config tab because navigation state was purely in-memory.
+
+The implementation added hash-based persistence with three key changes:
+1. Modified `navigation.svelte.ts` to read initial tab from `location.hash` on module init (browser only)
+2. Updated `setTab()` to call `history.replaceState()` after state changes, updating the hash without polluting browser history
+3. Exported `initNavFromHash()` function that sets up a `hashchange` event listener for back/forward navigation
+
+The solution uses `replaceState` instead of `pushState` to avoid creating history entries for tab switches—this prevents the annoying behavior of clicking through tabs then hitting back repeatedly.
+
+Validation is handled via a `VALID_TABS` set containing all valid tab IDs. Invalid hashes fall back to the default config tab.
+
+Implementation was verified with manual testing: tab state persists on refresh, direct hash navigation works, and unsaved changes warnings still fire when switching tabs.
