From ff5186dbc396cb6335025e7de5f1cfc5d60365b8 Mon Sep 17 00:00:00 2001 From: Molecule AI Core-DevOps Date: Mon, 11 May 2026 09:48:20 +0000 Subject: [PATCH] fix(ci/harness-replays): fetch base branch by name not SHA MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit git fetch origin : is not valid syntax for fetching an arbitrary commit (git needs a ref to locate the commit on the remote). Switch to git fetch origin main --depth=1 which fetches the main branch tip + its immediate parent. The base commit is the parent of the PR head on main, so depth=1 is sufficient. github.event.pull_request.base.ref = "main" (confirmed from API) — this is the branch name, not the SHA. git fetch origin main --depth=1 fetches the branch tip and one ancestor, giving us the base commit in a single cheap network call.
