From ee1af38390771f8c6477b665669aacfbd5b45138 Mon Sep 17 00:00:00 2001 From: openhands Date: Tue, 17 Mar 2026 10:02:58 +0000 Subject: [PATCH 1/3] fix: feat: Woodpecker CI pipeline with ShellCheck + duplicate code detection (#45) - Add .woodpecker/ci.yml: two-step pipeline (shellcheck + duplicate detection) - Add .woodpecker/detect-duplicates.py: sliding-window hash detection (5-line windows, 2+ files) plus grep-based anti-pattern checks (hardcoded CI_STATE, hardcoded WOODPECKER_REPO_ID).
