+# Phase 27 Plan 00: Wave 0 E2E Test Scaffolding Summary
+
+Wave 0 E2E scaffolding: replaced old dashboard card assertions with TopNav and discovery section tests, removed Setups tab from Collection specs, added standalone /setups route and mobile bottom tab bar tests.
+
+## What Was Done
+
+### Task 1: Update dashboard E2E tests
+
+Updated `e2e/dashboard.spec.ts` to match the post-Phase-27 navigation structure:
+
+- Replaced "shows Collection, Planning, and Setups card headings" with "shows discovery section headings" — now asserts `Popular Setups`, `Recently Added`, and `Trending Categories` section headings
+- Replaced "Collection card links to /collection" with "top nav contains Collection link" — now uses `page.locator("nav")` to find the nav link
+- Added "shows top nav with navigation links" — asserts Home, Collection, Setups are present in the nav element
+- Added "shows bottom tab bar on mobile viewport" — sets viewport to 375x667 and asserts Home, Collection, Setups, Search tab labels are visible
+- Marked "shows collection card with item count of 6", "shows active thread count on Planning card", and "shows setup count on Setups card" as `test.fixme` with explanatory comments about the Phase 27 removal
+
+The "shows GearBox heading" test remains unchanged — GearBox text is still visible as the nav logo.
+
+### Task 2: Update collection E2E tests
+
+Updated `e2e/collection.spec.ts` to reflect Setups tab removal from Collection:
+
+- Replaced "navigates to setups tab" (which asserted Weekend Overnighter at `/collection?tab=setups`) with "setups tab URL falls back to gear tab" — asserts Zpacks Duplex is visible instead
+- Added new `test.describe("Setups page")` block with "navigates to /setups and shows seeded setup" test
+- All Gear tab tests, planning tab test, and gear-is-default test are unchanged
+
+## Commit
+
+- `94e2094` — test(27-00): wave 0 E2E scaffolding for Phase 27 nav restructure
+
+## Deviations from Plan
+
+None — plan executed exactly as written.
+
+## Known Stubs
+
+None. These are test files only — no UI stubs introduced.
+
