Pipeline resilience: prevent artifact loss and cascading failures#653
Merged
Conversation
Never rmtree version directories containing H5 files on fingerprint mismatch — update fingerprint and resume instead. Pin fingerprint in RunMetadata so resumed runs aren't invalidated by branch drift. Add validation pre-flight to catch schema mismatches before spawning workers, and harden error dicts with stderr fallback/truncation and traceback capture. Add CI tests for query-schema compatibility. Closes #652 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
