+# Regression: `/categories` must not render campaign edit
+
+## Symptom (fixed)
+Nav/URL on **Categories** (`/categories`) sometimes showed **Edit campaign** chrome with a blank body.
+
+## Cause notes
+- Route files are distinct: `routes/categories/+page.svelte` vs `routes/campaigns/[id]/+page.svelte`.
+- SvelteKit dictionary maps `/categories` → categories page and `/campaigns/[id]` → campaign edit.
+- Campaign edit previously rendered `PageShell` titled "Edit campaign" even when `page.params.id` was empty (blank body) — that shell must never linger across client navigations.
+
+## Guards added
+1. Root dashboard layout keys page content by `page.url.pathname` so prior route shells unmount on nav.
+2. Campaign edit redirects to `/campaigns` when `id` is missing; wizard is keyed by `campaignId`.
+
+## Quick check
+1. Open `/campaigns/<any-id>` (or list), then click **Categories** in the nav.
+2. Assert H1 is **Categories** and body shows the category tree (not "Edit campaign").
+3. Hard-load `/categories` — same result.
