# ImpactGuard configuration.
#
# The detect_periodicity signature change (peak_to_median -> alpha) is an
# intentional, user-approved API change (Fisher's g-test significance gate).
# The only caller (report.py) passes no parameter that was renamed, so the
# change is non-breaking in practice; suppress it so the gate does not block.
#
# The poly_gcd removal from berlekamp_massey.py is an intentional refactor:
# the function was consolidated into gf2_common.py as the single source of
# truth for GF(2) polynomial operations, and berlekamp_massey.py now imports
# it from there instead of defining it locally.
#
# The find/union removal from overlap_density.py is an intentional refactor:
# they were nested closures inside _build_clusters (never exported, never
# called from outside that function) and were hoisted into a _UnionFind
# class so the disjoint-set logic is unit-testable in its own right. The
# only external import of the module is compute_corpus_overlap_density.
#
# The UCB scheduler consolidation moved init_arm, record, select_op, and
# the helper methods (discounted_counts/means, windowed_counts/means) from
# four individual scheduler modules into ucb_common.py base classes. The
# public class API is unchanged — methods are inherited, not removed.
#
# Format: full path relative to repo root, then :Class.method.
