R2 — Order Analysis pivot tree PROD · GATE 2

Live on prod 2026-05-20. Second piece of the H5 Reports arc — Odoo-pivot-modeled Order Analysis tree at /cafe/reports/order-analysis. Hierarchy Total → Month → Store → Session with expandable rows; columns Order count / Product quantity / Total price. Filter bar: month picker (prev/next + popover w/ native type="month" input) + multi-select stores. Validated on get-coffee (Pro, multi-month real data) + lumiere-coffee (Starter).

10/10 prod · 51/51 regression = 61/61 total green. 1 commit to nix-cafe (fca0065) — clean ship, no follow-up fix needed (R1's usePathname() lesson applied from day 1). No backend migration, no new deps. usePathname() wired correctly so all nav assertions passed on the first prod run.

Prod test — 10/10

✓ Login on get-coffee + Order Analysis link present on /cafe/reports
✓ Header link navigates to /cafe/reports/order-analysis (no 5xx)
✓ Pivot tree — Total + Month rows visible
✓ At least one store row OR empty state rendered
✓ Month prev arrow shifts URL → ?month=2026-04
✓ Month popover input change → URL ?month=2026-03
✓ Expanding a store row reveals its session rows; collapse restores
✓ DAO probe — aggregateOrderAnalysis against prod DB
✓ Hierarchy invariants hold on prod: sum(stores) == total, sum(sessions) == store
✓ Login on lumiere-coffee Starter + page renders (Total row visible)

51/51 regression green — no regressions from this push.

Out of scope / followups

Session numbering — current label is posConfigName • opened_at. Odoo's pivot shows 00080-style 5-digit session numbers; that identifier doesn't exist directly in cafe.* schema. Can derive a per-shop-per-day sequence if Narong wants the Odoo shape exactly.

Multi-month view — current filter is single-month per spec. Multi-month would flatten "Month" into expandable rows.

PDF export — stub button only.

Cross-month sessions — rare edge case where a session opened outside the filter month but has orders inside it. Renders under "—" store label.

🎉 Reports arc closed

Both pieces of the H5 Reports section from the v0.2 Notion doc (restructured 2026-05-18) now live on prod:

R1 — At-a-glance Sales Summary ✅ shipped 2026-05-20 (62/62)
R2 — Order Analysis pivot tree ✅ shipped 2026-05-20 (61/61)

H5.12 (Odoo mapping interface) still parked in "Future Release" — separate scoping needed.
