From 69148f54f54f29ccf340de53a2c7932eea739def Mon Sep 17 00:00:00 2001 From: Johannes du Plessis Date: Thu, 25 Jun 2026 14:11:21 -0700 Subject: [PATCH] feat: add PR trace resolution (#1612) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * feat: add PR trace resolution Co-authored-by: open-swe[bot] * fix: inject reviewer trace context as JSON Co-authored-by: open-swe[bot] * fix: address review on PR trace resolution Use the documented LangSmith metadata filter syntax (and(eq(metadata_key,...), eq(metadata_value,...))) instead of has(metadata, '{...}'), which does not match runs — _list_thread_runs was silently returning nothing. Bound full-text searches to a 90-day window so they don't hit LangSmith's large-window rate limit. Also folds in the best-effort branch->head-sha resolver (dropping the weighted scoring/threshold + repo/file evidence + GitHub hydration), sandbox JSON injection, and the admin "Resolve trace" dry-run endpoint. The IDOR findings are moot: resolve_pr_to_threads/summarize_agent_session were removed; resolution now runs deterministically from the trusted run config with no model-controlled pr_url or thread_id. * fix: scope branch trace search to the repo Branch names like fix-tests aren't unique across repos (or older PRs) in a shared tracing project, so an unscoped branch hit could resolve to an unrelated thread and write its runs into the reviewer sandbox. Require the repo slug to co-occur with the branch in matched runs; the full head SHA stays unscoped since it is globally unique.
