Added #393 Introduced new method graphix.optimization.StandardizedPattern.extract_partial_order_layer which constructs a partial order layering from the dependency domains of M, X and Z commands. Introduced new methods graphix.optimization.StandardizedPattern.extract_causal_flow, graphix.optimization.StandardizedPattern.extract_gflow which respectively attempt to extract a causal flow and a gflow from a standardized pattern. Introduced new wrapper methods in the Pattern class: graphix.pattern.Pattern.extract_partial_order_layers, graphix.pattern.Pattern.extract_causal_flow and graphix.pattern.Pattern.extract_gflow. Introduced new module graphix.flow._partial_order with the function :func:compute_topological_generations. #392: Added graphix.pattern.Pattern.remove_input_nodes method which removes the input nodes from the pattern and replaces them with N commands. #385 Introduced graphix.flow.core.XZCorrections.check_well_formed which verifies the correctness of an XZ-corrections instance and raises an exception if incorrect. Added XZ-correction exceptions to module graphix.flow.core.exceptions. #378: Introduced new method graphix.flow.core.PauliFlow.check_well_formed, graphix.flow.core.GFlow.check_well_formed and graphix.flow.core.CausalFlow.check_well_formed which verify the correctness of flow objects and raise exceptions when the flow is incorrect. Introduced new method graphix.flow.core.PauliFlow.is_well_formed which verify the correctness of flow objects and returns a boolean when the flow is incorrect. Introduced new module graphix.flow.exceptions grouping flow exceptions. Introduced new methods graphix.flow.core.PauliFlow.get_measurement_label and graphix.flow.core.GFlow.get_measurement_label which return the measurement label of a given node following same criteria employed in the flow-finding algorithms. #379: Added a new instruction CZ which can be added as a circuit gate using circuit.cz. Introduced new method graphix.opengraph.OpenGraph.is_equal_structurally which compares the underlying structure of two open graphs. Added new method isclose to graphix.fundamentals.AbstractMeasurement which defaults to == comparison. #383: Simulators are now parameterized by PrepareMethod (which defaults to DefaultPrepareMethod) to customize how N commands are handled, and the class BaseN can be used as a base class for custom preparation commands. #394: The method Circuit.transpile_measurements_to_z_axis returns an equivalent circuit where all measurements are on the Z axis. This can be used to prepare a circuit for export to OpenQASM with circuit_to_qasm3. #402: Support for Python 3.14. #253, #406: Added classes BaseCommand and BaseInstruction. #407: Introduced new method graphix.optimization.StandardizedPattern.extract_xzcorrections and its wrapper graphix.pattern.Pattern.extract_xzcorrections which extract an XZCorrections instance from a pattern. #412: Added pretty-print methods (to_ascii, to_latex and to_unicode) for PauliFlow and XZCorrections classes. Implemented their __str__ method as a call to self.to_ascii. Fixed #363, #392: Pattern.remove_input_nodes is required before the Pattern.perform_pauli_measurements method to ensure input nodes are removed and fixed in the |+> state. #379: Removed unnecessary meas_index from API for rotation instructions RZ, RY and RX. #347: Adapted existing method graphix.opengraph.OpenGraph.isclose to the new API introduced in #358. #349, #362: Patterns transpiled from circuits always have causal flow. #383: Pattern.check_runnability no longer fails on custom BaseM commands without domain information. #389, #391: Pattern.extract_opengraph raises an exception if pattern has N commands which do not represent a |+> state. #177, #404: Fixed pattern export to OpenQASM 3. Compatibility with Qiskit is ensured with normalization passed incorporate_pauli_results and single_qubit_domains. #231, #405: IXYZ is now defined as Literal[I] | Axis. #382, #409: Axis labels are shown when visualizing a pattern. Legend is placed outside the plot so that the graph remains visible. #407: Fixed an unreported bug in OpenGraph.is_equal_structurally which failed to compare open graphs differing on the output nodes only. #157, #417: Pattern.minimize_space uses Pattern.extract_causal_flow() and preserves runnability Changed #396: Removed generic BackendState from graphix.sim modules and methods in graphix.pattern and graphix.simulator modules. #374: Adapted existing method graphix.opengraph.OpenGraph.isclose to the new API introduced in #358. #375: Adapted existing method graphix.opengraph.OpenGraph.compose to the new API introduced in #358. #352, #394: Circuit measurements are now limited to axes X, Y, and Z. #233, #399: The angle convention is now consistent across the library: angles are represented as floats and expressed in units of π. In particular, angles that appear in parameters of circuit instructions are now expressed in units of π. #407: Modified the constructor XZCorrections.from_measured_nodes_mapping so that it doesn't need to create an nx.DiGraph instance. This fixes an unreported bug in the method. Removed modules graphix.gflow and graphix.find_pflow. #369, #414: random_objects.py and tests are now type-checked. #418: Pattern.extract_measurement_commands now returns a dictionary. Removed Pattern.get_meas_plane and Pattern.get_angles. #220, #418: get_/set_-prefixed functions are renamed with more meaningful names.
