* Remove seq_state: embed tracked_str_eq/tracked_str_mem directly in prop_queue Co-authored-by: NikolajBjorner <3085284+NikolajBjorner@users.noreply.github.com> * theory_nseq: use type aliases for eq_item/mem_item instead of wrapper structs Co-authored-by: NikolajBjorner <3085284+NikolajBjorner@users.noreply.github.com> * seq_model: validate_regex takes single tracked_str_mem, caller loops Co-authored-by: NikolajBjorner <3085284+NikolajBjorner@users.noreply.github.com> --------- Co-authored-by: copilot-swe-agent[bot] <198982749+Copilot@users.noreply.github.com> Co-authored-by: NikolajBjorner <3085284+NikolajBjorner@users.noreply.github.com>

Abstract:
|
|
|
|
Tracked constraint types bridging the SMT context to the Nielsen graph.
|
|
tracked_str_eq and tracked_str_mem extend the core constraint types with
|
|
SMT-layer source information (enodes and literals) for conflict reporting.
