Tier 1 regression: expected_undelivered.py carries its own BASE=dirname(__file__) anchor (a duplicate of paths.py). The package move dropped the file one level deeper, so BASE resolved to inbound_verify/ and DOWNLOADS/OUTPUT pointed at non-existent inbound_verify/downloads|output — while site downloads write to the project-root dirs via paths.py. process()/write_site_file() thus skipped the compare with '[跳过] downloads 下缺少 ...', returned None/False, and every undelivered task for the 4 web/app sites reported failed (重试耗尽) despite the files downloading fine. Fix: anchor BASE two levels up (mirrors paths.py). Verified: write_site_file returns True; all 4 undelivered tasks now success with 未到 files generated.
