From be233b5e14ec730cafd06c6208bb462a5f3b9006 Mon Sep 17 00:00:00 2001 From: JUN Date: Mon, 14 Sep 2026 22:44:07 +0900 Subject: [PATCH 1/3] feat(usage): report sends, spend and cache provenance per logical request (#4546) Part of the stacked delivery closing the remaining OCX-4546 cost-guard scope. Verification posture: local suite, typecheck, install and build NOT run by explicit instruction. Hosted CI at the exact final head is the only proof.

The grace entry is the mechanism the check itself names. The plan it stands for: the usage-aggregation half of this doc is now large enough to be its own page, and splitting it is a separate change that touches no source.
