Summary

AI summary

Updates Surfaces shipping in v1.15.0, Tests, and UUIDv7 across a mixed release.

Full changelog

Identity Graph (v2.0 headline feature)

A durable, queryable graph layer above run-local clusters. Stable entity_id (UUIDv7) per identity, source-record nodes, evidence edges, append-only event log, aliases.

SQLite default, Postgres optional. Resolve runs after dedupe clustering; idempotent on (run_name, kind, entity_id). Additive feature -- failure logs + skips, never blocks dedupe output.

Earlier breaking changes

v3.1.0 `GOLDENMATCH_FRAME=polars` now requires the `[polars]` extra; raises error without it.
vgoldencheck-v3.0.0 `inferred_type` emits neutral dtype vocabulary (str/int/uint/float/date/datetime/bool/other) instead of raw Polars dtypes.
vgoldencheck-v3.0.0 'inferred_type' now emits a neutral dtype vocabulary instead of raw Polars dtype strings.
vgoldencheck-v3.0.0 `scan_file`, `scan_dataframe`, and CLI `check` now run without Polars, using Arrow-native pyarrow.Table.
v3.0.0 Result frames now return pyarrow.Table instead of Polars DataFrame.
