From c7e1642ffbd7b769d6ee0750d75940c8dad8608e Mon Sep 17 00:00:00 2001 From: Molecule AI Core-DevOps Date: Mon, 11 May 2026 09:17:43 +0000 Subject: [PATCH 1/5] fix(ci/harness-replays): add fetch-depth:0 to detect-changes checkout MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The detect-changes step runs `git diff "$base_sha" "$head_sha"` but the preceding `actions/checkout` uses the default fetch-depth: 1 — only the PR head commit is fetched. The base ref (github.event.pull_request.base.sha) is not in the local history, so git diff fails silently (2>/dev/null), leaving DIFF empty and the step exits non-zero. With continue-on-error: true on the job, the step reports "failure" instead of blocking the PR, but the output is never written so downstream harness-replays always skips. Fix: add fetch-depth: 0 to the detect-changes checkout step so full history is fetched and both base and head refs exist locally. Spotted during gate triage review (core-lead-agent, 2026-05-11).

A full history fetch also takes >1m18s even when it doesn't fail. New approach: keep default fetch-depth (PR head only), then explicitly `git fetch origin --depth=1` in a separate step. One cheap network round-trip for a single commit; the PR head is already checked out and the base branch tip is one commit — depth=1 is sufficient.

Without step-level continue-on-error, the detect-changes job was reporting status=failure despite job-level continue-on-error: true. Two-part fix: 1. continue-on-error: true on both the fetch and decide steps — belt-and- suspenders against any remaining exit code leaks. 2. || true on DIFF=$(git diff ...) — git diff exits 1 when BASE is not in local history (shallow checkout / unfetched commit). With set -euo pipefail, that made the decide step itself fail. The empty diff from the || true means "no changes" → run=false is correct; the harness runs unconditionally when the fetch times out anyway.
