From 3f6d0cb6f82c3e2f4f67c740ede5f7b0463e435e Mon Sep 17 00:00:00 2001 From: Max Ghenis Date: Fri, 17 Apr 2026 19:59:12 -0400 Subject: [PATCH 1/8] Relax manifest-vs-installed check to UserWarning `UKTaxBenefitModel.__init__` / `USTaxBenefitModel.__init__` previously raised `ValueError` on any mismatch between the bundled manifest's pinned model version and the installed `policyengine-uk` / `policyengine-us` version. That made every routine country-model patch bump require a coordinated pypkg manifest update, and when downstream core tightened its parameter validation (core 3.24.0's strict breakdown validator), every post-merge pypkg publish broke at import time because the stale pins in pypkg's extras couldn't install against modern core. Swap the `ValueError` for a `UserWarning`. Calculations now run against whatever country-model version is installed; dataset compatibility is still advertised via `model.release_manifest`, and downstream code that cares about exact pinning can inspect it. Adds a regression test verifying both models emit a UserWarning instead of raising on a version drift.

Without HUGGING_FACE_TOKEN env, instantiation fails before the version-warn branch is exercised. Rewrite the test to patch the network-dependent downstream calls (certify_data_release_compatibility, _get_runtime_data_build_metadata, TaxBenefitModelVersion.__init__) so only the version-check branch runs. Any downstream exceptions are caught since by then the warning has already been emitted (or the raise has already fired, which would fail the test correctly).
