omena-abstract-value

Internal Rust crate for the Omena abstract class-value domain.

This crate owns the generic domain contract used to reason about dynamic class values before they are projected into a selector universe.

Current public product:

• omena-abstract-value.domain — domain boundary summary for the abstract class-value lattice and selector projection certainty contract.
• intersect_abstract_class_values — reduced-product intersection over finite, prefix, suffix, character-inclusion, and composite class-value domains.
• join_abstract_class_values — least-upper-bound merge for branch-sensitive class-value flow.
• analyze_class_value_flow — V0 1-CFA flow analysis over explicit class-value flow graphs with assign/refine/join transfers.
• analyze_class_value_control_flow_graph — CFG-aware flow analysis that prunes unreachable blocks before evaluating class-value transfer facts.
• analyze_k_limited_call_site_flows — k-limited call-site context analysis for dynamic class helpers that need deeper-than-1-CFA discrimination.
• analyze_class_value_flow_incremental — the same flow analysis surfaced with an omena-incremental recomputation plan and next snapshot.
• analyze_class_value_flow_incremental_with_reuse — incremental flow analysis that reuses the previous result when the plan is clean.
• analyze_class_value_flow_incremental_with_database — Salsa-backed incremental flow entrypoint that keeps omena-incremental DB state across requests while preserving the existing analysis result contract.
• reduced_abstract_class_value_from_facts / reduced_value_domain_kind_from_facts — source fact reduction before evaluator-facing domain-kind reporting.
