 """Finance service — daily revenue vs cost reconciliation.
 
 Architecture:
-  - Website revenue: HTTP GET /usage/stats via website's existing auth config
-  - Upstream cost (Sub2API): HTTP GET /usage/stats via upstream's bearer token
-  - Upstream cost (New-API/Nox-API): HTTP GET /api/log/stat via UpstreamClient
-    (handles login_password / nox_token / new_api_token auth)
+  - Website revenue: Sub2ApiWebsiteClient._request("/usage/stats", params=...)
+    Reuses all existing error handling, logging, auth (api_key / bearer).
+  - Upstream cost (Sub2API): UpstreamClient._send_request(url, params=...)
+    within the client context — retains cookies, 401 refresh, external API log.
+  - Upstream cost (New-API/Nox-API): same UpstreamClient pattern.
 
-No DB writes. All data fetched live. Each item fails independently.
+No DB writes. Each item fails independently; failures do NOT contribute to
+totals, and the UI must treat any failed item as incomplete accounting data.
