parity

Cross-language parity harness

This directory contains the repo-level parity runner for proxyables.

Usage

Run the full matrix:

python3 parity/run.py

Run the full release gate:

python3 parity/run.py --profile release

Run the curated multihop chains:

python3 parity/run.py --profile multihop
python3 parity/run.py --profile multihop --chains go:py:ts:rs

Run a subset (canonical PascalCase IDs, legacy aliases also accepted):

python3 parity/run.py --langs ts,py,go --pairs ts:py,py:go --scenarios GetScalars,CallAdd

Keep unsupported pairs as informational instead of failing:

python3 parity/run.py --allow-unsupported

Contract

• Each language provides a parity agent with serve and drive modes.
• Multihop chains add a bridge mode that imports upstream and re-exports downstream over the real runtime path.
• Agents communicate readiness and scenario results over stdout as JSONL.
• The runner uses real TCP loopback sockets for the data plane.
• Protocol mismatches and missing capabilities are reported explicitly per pair and scenario.
• The agent protocol aligns with the shared constants and behaviors in DSL.md.
