litedbmodel-runtime 2.0.0

Thin multi-language runtime for litedbmodel v2 SCP §8 bundles (Python port). Interprets the published SqlBundle (sql + fragment tree + Expression-IR param slots + transaction plan, dialect-tagged) and executes it against a SQL driver — semantics-identical to the TS reference. Delegates Expression-IR evaluation to behavior-contracts.

litedbmodel-runtime (Python)

The Python leg of the litedbmodel v2 SCP multi-language runtime. Interprets the language-neutral §8 published bundle (SqlBundle) and executes it against a DB-API SQL driver, semantics-identical to the TS reference (src/scp).

Status: WS7a scaffold. The buildable package skeleton + the conformance runner entry point are here; the runtime body (render / execute / transaction) is WS7b.

behavior-contracts dependency

The runtime delegates the CLOSED Expression-IR evaluation to the shared common core behavior-contracts — consumed from PyPI (behavior-contracts==0.2.0), exactly as the TS reference imports it from npm. No local path dependency (the check-no-local-deps gate forbids ../-escaping deps).
