From 8a3ff92518ae120d0ed26c9a574e1472cba0d2e8 Mon Sep 17 00:00:00 2001 From: weichen Date: Wed, 7 Oct 2026 16:34:27 +0000 Subject: [PATCH] Add last-request and cache fields to Usage (N3 WP6) Why: the loop now emits Last* and cache token usage; the product run record needs the same fields for display and accounting (additive JSON, old records deserialize as zero values). Evidence: GOWORK=off go build + go test green. Impact: additive only.
