From 93cec6e6e68f2a176dc23fa5619391a4a47ec965 Mon Sep 17 00:00:00 2001 From: zhuowp <9426526+zhuowp@users.noreply.github.com> Date: Thu, 22 Oct 2026 04:32:16 +0000 Subject: [PATCH 01/13] fix(context): recover complete tool outputs Backport the recoverable output-budget slice of upstream #6619 so header-heavy Web responses retain their answers or a usable full-output ref. Share the route budget across engine, Web, provider wire and TUI. Adapt preservation to both fork execution paths, keep existing bounded child summaries and legacy ownership retrieval, reject conflicting full output replays, and distinguish body evidence from response envelopes. Harvested from PR #6619 by @Hmbown (codewhale-hq/Codewhale).
