Summary

Reduce argument-order drift risk while preserving explicit public signatures, annotations and positional compatibility.

Changes

• Use one consistent keyword-based forwarding pattern for JSON, YAML and report facades.
• Keep the public parameter lists explicit for typing and IDE completion; no kwargs abstraction or code generation.
• Characterization tests compare signatures and exercise every forwarding slot through positional and keyword calls.

Validation

• Characterization before refactor: 9 passed, 1703 deselected in 1.84s.
• make check-all passed: 1660 passed, 30 skipped, 22 deselected, 5 warnings in 26.57s; coverage remains above 95%.
• make build passed. Repository mypy passed; LSP tooling cannot access private worktree paths.
• GitHub CI pending.
