From 59c3275adfcf92b1218a571e8c5484c9bcbf9c59 Mon Sep 17 00:00:00 2001 From: Nora Date: Mon, 29 Jun 2026 12:51:28 -0600 Subject: [PATCH] feat(sp27): server-aggregate Dashboard KPIs so 100-row sample doesn't lie MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The Dashboard was hardcoded to useClaims({ limit: 100 }) and reduce KPIs client-side. With 60k+ claims in production, every tile (Billed $940K, Received $59K, Denial rate, Pending AR, monthly sparkline, top providers, recent denials) was computed from a 0.16% sample of the dataset — silently wrong numbers on the operator's primary view. Fix: add GET /api/dashboard/kpis that aggregates server-side in one read over the entire claim population. The new useDashboardKpis hook consumes it and polls every 60s. Dashboard.tsx drops useClaims({limit:100}) + useProviders() + the client-side buildMonthly reduce. Backend: - store.py: dashboard_kpis() — one Claim query (selectinload on batch to avoid N+1) + one bulk Remittance lookup, Python reduce over the full population. Zero-filled response for empty DB. - api.py: GET /api/dashboard/kpis behind matrix_gate, query-param clamps (1..24 months, 0..50 top_n_*). Frontend: - api.ts: DashboardKpis types + getDashboardKpis() wrapper. - useDashboardKpis.ts: TanStack Query hook, 60s refetchInterval, bypass to data:undefined when not configured. - Dashboard.tsx: switched to useDashboardKpis, extracted ZERO_TOTALS constant, dropped the buildMonthly helper. Tests: - backend/tests/test_dashboard_kpis.py: 12 tests covering empty DB, matched-remit math, pending-state semantics, monthly binning, top-providers/top-denials sort + cap, orphan-claim defensive guard, HTTP wiring + param validation. - src/hooks/useDashboardKpis.test.ts: 3 tests for the hook contract (configured path, unconfigured fallback, param passthrough). - src/pages/Dashboard.test.tsx: wrapped renders in QueryClientProvider + stubbed useAuth + isConfigured=false. This fixes 3 pre-existing Dashboard test failures (the page never had a QueryClient set up because useClaims/useProviders were the first useQuery hooks in the page). Reviewer fixes (same commit): 1. topDenials sort placed empty submissionDate claims first under reverse-lex. Drop them at append time. 2. r.batch lazy-load → N+1 on 60k rows. selectinload(Claim.batch). 3. pending_states rebuilt per call as a mutable set — moved to module-level _DASHBOARD_PENDING_STATES frozenset. 4. Module-level ProviderORM import inconsistent with the "local import inside the function" pattern — moved inline. --- backend/src/cyclone/api.py | 29 ++ backend/src/cyclone/store.py | 291 ++++++++++++++++ backend/tests/test_dashboard_kpis.py | 500 +++++++++++++++++++++++++++ src/hooks/useDashboardKpis.test.ts | 126 +++++++ src/hooks/useDashboardKpis.ts | 47 +++ src/lib/api.ts | 81 +++++ src/pages/Dashboard.test.tsx | 50 ++- src/pages/Dashboard.tsx | 140 +++----- 8 files changed, 1173 insertions(+), 91 deletions(-) create mode 100644 backend/tests/test_dashboard_kpis.py create mode 100644 src/hooks/useDashboardKpis.test.ts create mode 100644 src/hooks/useDashboardKpis.ts diff --git a/backend/src/cyclone/api.py b/backend/src/cyclone/api.py index 4ac1958..974ef53 100644 --- a/backend/src/cyclone/api.py +++ b/backend/src/cyclone/api.py @@ -88,6 +88,7 @@ from cyclone.store import ( AlreadyMatchedError, BatchRecord, InvalidStateError, + dashboard_kpis, store, utcnow, ) @@ -2291,6 +2292,34 @@ def get_remittance(remittance_id: str) -> dict: return body +@app.get("/api/dashboard/kpis", dependencies=[Depends(matrix_gate)]) +def get_dashboard_kpis( + months: int = Query(6, ge=1, le=24), + top_n_providers: int = Query(4, ge=0, le=50), + top_n_denials: int = Query(5, ge=0, le=50), +) -> dict: + """Server-aggregated Dashboard KPIs over the whole claim population. + + Backs the Dashboard's "Claims / Billed / Received / Pending AR / + Denial rate" tiles + the monthly sparkline series + the + top-providers and top-denials lists. + + Why this exists instead of ``GET /api/claims?limit=N``: + The Dashboard's KPIs are aggregates over *every* claim — billed, + received, denial rate, pending count, monthly billed/received.
