+### Session 2026-03-29b — Wizard steps 5-15 (complete flow)
+
+**Agent(s):** Claude Opus 4.6 (1M context)
+
+**Work completed:**
+- **Step 5 — AuthGateStep:** Centered-form, 3 progressive sub-steps (SSO/email → details → verify). Phone optional when email-only. Benefit framing ("Save your plan"). Audit 18/20, P1 fixed (responsive name fields).
+- **Step 6 — DateTimeStep:** Centered-form, two fieldset sections (name + scheduling). Grief-sensitive labels ("Their first name"). Date/time radios + Autocomplete for religion (22 options). Save-and-exit CTA.
+- **Step 7 — VenueStep:** Venue card grid (1-2 col) with search/filters. Inline venue detail (Collapse) with features + religions. Service toggles (photo, streaming, recording) via AddOnOption. VenueCard extended with selected + ARIA passthrough props.
+- **Step 8 — CrematoriumStep:** Single crematorium confirmation card (most common) or multi-card grid. Witness question personalised with deceased name. Special instructions via progressive disclosure textarea.
+- **Step 9 — CemeteryStep:** Triple progressive disclosure (have plot? → choose cemetery? → card grid). Dependent field resets. "Provider can arrange this" shortcut.
+- **Step 10 — CoffinsStep:** 3-col card grid with category/price filters. "Most Popular" badge (Rec #10). Pagination support. Australian terminology ("coffin").
+- **Step 11 — CoffinDetailsStep:** Coffin profile (image + specs grid) + 3 product option RadioGroups (handles, lining, nameplate) with branded selected state. Price: "Included" or "+$X".
+- **Step 12 — AdditionalServicesStep:** Merged from optionals + extras (Rec #2). Section 1: complimentary (dressing, viewing, prayers, announcement). Section 2: paid (catering, music, bearing, newspaper). Multi-level progressive disclosure.
+- **Step 13 — SummaryStep:** Accordion sections with edit buttons, dl/dt/dd definition lists, total bar (aria-live), share button. Pre-planning: "Save your plan" / at-need: "Confirm".
+- **Step 14 — PaymentStep:** ToggleButtonGroup for plan (full/deposit) + method (card/bank). PayWay iframe slot. Bank transfer details display. Terms checkbox. Security reassurance.
+- **Step 15 — ConfirmationStep:** Terminal page, no back/progress. At-need: "submitted" + callback info. Pre-planning: "saved" + return-anytime. Muted success icon, next-steps links.
+
+**Approach:** Same as previous session — first pass build + quick audit + P0/P1 fixes only. Grooming pass comes later.
+
+**Decisions made:**
+- VenueCard extended with selected/ARIA props (same pattern as ProviderCard from step 2)
+- VenueStep uses centered-form not grid-sidebar (simpler for first pass, can upgrade later)
+- CoffinDetailsStep uses OptionSection helper component for DRY RadioGroup rendering
+- SummaryStep uses Accordion not Paper for sections (per spec's collapsible requirement)
+- PaymentStep uses slot pattern for PayWay iframe (cardFormSlot prop)
+
+**Open questions:**
+- None
+
+**Next steps:**
+- All 15 wizard steps are now first-pass complete (steps 1-15)
+- Grooming pass: /critique, /harden, /polish, /normalize across all steps
+- Retroactive review backlog still pending
+- Integration: routing, state management, GraphQL queries
