ttr-plan-proto 0.9.0

Canonical wire formats for the TTR-P plan pipeline (plan.v1 / transdsl.v1 / dfdsl.v1)

ttr-plan-proto (Python)

Pre-generated Python message classes for the TTR-P plan pipeline wire formats: plan.v1, transdsl.v1, dfdsl.v1. Importable at their canonical module paths, e.g. from org.tatrman.plan.v1 import plan_pb2.

Canonical source of truth: the .proto files in the sibling Kotlin module ../../kotlin/ttr-plan-proto/src/main/proto/. tatrman owns the wire format once (decision TR-3); this wheel and the org.tatrman:ttr-plan-proto Maven jar are the per-language published artifacts. Formerly generated inside kantheon shared/proto; transferred at f2e2efb (2026-07-06). See docs/ttr-translator/.

Build

Pure-Python wheel (py3-none-any). The build hook (hatch_build.py) runs grpcio-tools' bundled protoc over the sibling .proto files — no JVM needed. The generated src/org/** tree is gitignored and regenerated on every build.

uv build --wheel                 # or: pipx run build --wheel
uv run --with protobuf --with pytest pytest tests/

Released to PyPI via python-plan/v<x.y.z> (trusted publishing); versioned in lockstep with the Maven kotlin-translator/v* pair by convention.

Governance

Proto changes are driven by kantheon runtime needs (typically PipelineContext); they arrive as PRs to this repo, which cuts a prompt lockstep release. Field numbers/types are append-only within v1 (see docs/ttr-translator/architecture/contracts.md §2).
