v2.1.0

v2.1.0

Added

• Causal reasoning v2 (Section 7): Structural Ranking Models (SRM) with surgery (do()), stable reasons (causation), and total effects in rank space.
• Ranked CI + PC discovery with v-structures and Meek R1/R2 orientation.
• Identification utilities: backdoor/frontdoor admissibility and τ-based effect estimation.
• Explanations: minimal repairs (enumeration; optional CP-SAT) and root-cause DOT export.
• New examples: examples/causal_boolean_circuit_srm.py, examples/causal_srm_identification_demo.py.
• Optional extras (pyproject.toml) for solver backends: cp-sat, maxsat, asp, z3.

Changed

• Expanded documentation: Section 7 design + checklist; updated causal tutorial; enriched README.
• Clarified belief propagation and Spohn conditionalization notes.

Notes

• Remaining gaps planned for future minors: Meek R3/R4, FCI/PAG, c-representations/SMT, measurement/IC axioms.
