+# Phase 17 Plan 02: Planning Page Restyle Summary
+
+**TDD RED/GREEN cycle for the go-backend/ planning view: overview-section heading with h1, day-separated event list using PlanningShowDaySeparator, and empty-state via ui.EmptyState — CSS h1 selector also extended.**
+
+## Performance
+
+- **Duration:** ~15min
+- **Started:** 2026-05-17T10:10:00Z
+- **Completed:** 2026-05-17T10:25:00Z
+- **Tasks:** 3 (2 auto-TDD + 1 browser checkpoint auto-approved)
+- **Files modified:** 6
+
+## Accomplishments
+
+- `go-backend/internal/web/ui/app.css`: `.overview-section-heading h1` prepended to the heading selector — h1 now inherits 1.6rem 600-weight style matching h3 section headings
+- `go-backend/internal/web/views/planning_view.go`: `PlanningEventRow`, `PlanningTabData`, `NewPlanningTabData` (5 demo events across 2 dates), `PlanningShowDaySeparator` — view model + day-separator logic
+- `go-backend/internal/web/views/planning_view_test.go`: `TestPlanningShowDaySeparator` (table-driven logic tests GREEN), `TestPlanningMainContentRendersOverviewSection` (render assertions)
+- `go-backend/internal/web/views/dashboard_components.templ`: `PlanningMainContent(data PlanningTabData)` replaces the zero-arg stub — renders overview-section heading (h1), day separators with `data-day-separator="true"`, event rows, empty state
+- `go-backend/internal/web/handlers/auth.go`: `GetPlanningPage` passes `views.NewPlanningTabData()` to `views.PlanningMainContent()`
+- Full test suite passes: `go test ./... -count=1` exits 0
+- Task 3 (browser verify): auto-approved (auto_advance = true)
+
+## Task Commits
+
+1. **Task 1: CSS h1 selector fix + view model + render and logic tests (RED)** — `1afc39e` (test)
+2. **Task 2: PlanningMainContent() templ component + handler wiring (GREEN)** — `9fe6c89` (feat)
+3. **Task 3 (checkpoint) — browser verify** — auto-approved
+
+## Files Created/Modified
+
+- `go-backend/internal/web/views/planning_view.go` — PlanningEventRow, PlanningTabData, NewPlanningTabData, PlanningShowDaySeparator
+- `go-backend/internal/web/views/planning_view_test.go` — TestPlanningShowDaySeparator, TestPlanningMainContentRendersOverviewSection
+- `go-backend/internal/web/ui/app.css` — h1 prepended to .overview-section-heading selector
+- `go-backend/internal/web/views/dashboard_components.templ` — PlanningMainContent replaced
+- `go-backend/internal/web/views/dashboard_components_templ.go` — regenerated by templ generate
+- `go-backend/internal/web/handlers/auth.go` — GetPlanningPage passes NewPlanningTabData()
+
+## Decisions Made
+
+- `planning_view.go` chosen as the file location for `PlanningShowDaySeparator` (CONTEXT.md D-P02 referenced `planning_forms.go` but that file doesn't exist in go-backend/ — path adaptation, not decision override)
+- Demo data uses 5 hardcoded events across 2 date labels — ensures separator renders correctly (2 separators visible in demo)
+- `data-day-separator="true"` attribute added to separator div — render test asserts this attribute, decoupled from Tailwind class names
+- backend/ planning page was already done in Plan 17-01 (commit 56194cf) — no duplicate work
+
+## Deviations from Plan
+
+None — plan executed exactly as written.
+
+The critical_context note was accurate: backend/ planning.templ and app.css were already updated in Plan 17-01. Plan 17-02's scope is the go-backend/ TDD prototype implementation, which was not yet done. All 4 go-backend/ artifacts were created fresh in this plan.
+
+## TDD Gate Compliance
+
+- RED commit `1afc39e`: view model + logic tests + render test (package build failure confirmed — `PlanningMainContent` zero-arg vs one-arg mismatch)
+- GREEN commit `9fe6c89`: templ component + handler wiring (`go test ./... -count=1` exits 0)
+- No REFACTOR commit needed.
+
+## Verification
+
+```
+go test ./internal/web/views/ -run TestPlanningShowDaySeparator -count=1  → PASS
+go test ./internal/web/views/ -run TestPlanningMainContentRendersOverviewSection -count=1  → PASS
+go test ./internal/web/views/ -run TestPlanning -count=1  → PASS
+go test ./... -count=1  → all packages pass
+go build ./...  → exits 0
+```
+
+## Known Stubs
+
+- `NewPlanningTabData()` returns hardcoded demo data — intentional per plan scope note. Real data wiring deferred to when go-backend/ gets a live data layer. The real running backend/ app already uses live database queries via `handlers_planning.go` and `planning_forms.go`.
+
+## Threat Flags
+
+No new threat surface introduced. All `{ expr }` interpolations in `PlanningMainContent` use templ auto-escaping for DateRange, DateLabel, TimeRange, Title, TabloTitle, Location. T-17-02-01 mitigated. T-17-02-02 accepted (auth unchanged, demo data only in go-backend/).
+
