- feat: update payload generation and execution requests handling
- feat: update Grafana K6 image version to 2.1.0 in configuration files
- Introduced functionality to generate execution payloads for a specified block range using the `expb generate-payloads` command. - Enhanced documentation in README.md and USAGE.md to include details on payload generation and command usage. - Updated the `Generator` class to fetch beacon blocks and construct payloads according to the latest specifications. - Implemented encoding for execution requests as per EIP-7685, including deposits, withdrawals, and consolidations. - Added unit and integration tests to validate the encoding of execution requests and blob versioned hashes against real mainnet data. - Updated dependencies in pyproject.toml to include `requests` and `pytest` for improved functionality and testing. - Refactored code to improve clarity and maintainability, including the introduction of helper methods for encoding and fetching data.
Engine-emitted k6 metrics (k6_iterations_total, k6_vus, k6_data_*) do not inherit script-side options.tags in the Prometheus remote-write output, so moving testid to options.tags dropped the label from those series. Restore testid as an output-level --tag alongside the existing --env.
The prior fix only added testid. tool and client_type are likewise run-general but live in the script's options.tags / scenario tags, which k6's Prometheus remote-write output does not attach to engine-emitted metrics (k6_iterations_total, k6_vus, k6_data_*). Pass all three as output-level --tag so every series carries them.
