Execution Log Normalizer

Turn a redacted execution event into a deterministic record before classifying or retrying it.

Scenario and prerequisites

• - Use with an n8n-like execution export or an equivalent workflow failure record.
• Input must be authorized and redacted; do not include credentials, cookies, tokens, or private customer payloads.
• Python 3.10+ and the standard library are enough.

Input and output

Input needs execution_id, workflow_name, status, failed_node, error_message, started_at, and retry_count. Output is READY or BLOCKED, plus a stable failure fingerprint and explicit missing-field reasons.

Execution and recovery

Run python scripts/normalize_execution.py --input examples/input.json --output examples/output.json. Add missing fields or redact the payload and rerun. This script never reads an n8n instance or retries an execution.

Acceptance

The normal sample produces READY and a non-empty fingerprint; the broken sample produces BLOCKED.
