* Initial plan
* Refactor sat_solver.cpp to use structured bindings for pairs
- Line 1398: Changed priorities[i].second to use [priority, var]
- Lines 2154-2156: Changed p.first/p.second to use [l1, l2] for binary clauses
- Lines 4182-4184: Eliminated intermediate l1, l2 variables using [l1, l2] binding
This modernizes the code to use C++17 structured bindings instead of .first/.second member accesses.

* Initial plan
* Refactor mk_and and mk_app to use std::span
- Made mk_and(unsigned num_args, expr * const * args) private
- Added new public mk_and(std::span<expr* const> args) method
- Added new public mk_app(family_id fid, decl_kind k, std::span<expr* const> args) method
- Updated all convenience overloads to use std::span version
- Updated all external call sites to use the new std::span API
Co-authored-by: NikolajBjorner <3085284+NikolajBjorner@users.noreply.github.com>
* Fix remaining test files to use std::span API
- Updated src/test/sorting_network.cpp
- Updated src/test/ho_matcher.cpp with explicit cast to resolve ambiguity

* Revert overlapping changes superseded by PR #8286
Reverted 30 files to match the state from PR #8286 (commit ebc0688) which refactored mk_and/mk_or call sites to use vector overloads. This supersedes the std::span changes in those files.
Retained std::span changes in files unique to this PR:
- Core API changes (ast.h, ast.cpp)
- Files not affected by PR #8286 (api_context.cpp, ast_util.cpp, bool_rewriter.h, datatype_rewriter.cpp, dom_simplifier.cpp, factor_rewriter.cpp, pb2bv_rewriter.cpp, quant_hoist.cpp, spacer_cluster_util.cpp, sortmax.cpp, array_axioms.cpp, smtfd_solver.cpp, goal.cpp, ho_matcher.cpp, qe_arith.cpp, sorting_network.cpp)
- Special case in hnf.cpp where both PRs modified different lines

* Initial plan
* Refactor mk_and and mk_or call sites to use overloaded methods
Changed 130 call sites across 64 files to use vector overloads directly instead of manually passing .size() and .data()/.c_ptr()

* Revert mk_or changes for ptr_buffer/ptr_vector (no overload exists in ast_util.h)
* Fix compilation errors from mk_and/mk_or refactoring
Fixed type mismatches by:
- Removing m parameter for expr_ref_vector (ast_util.h has mk_and/mk_or(expr_ref_vector) overloads)
- Reverting changes for ref_buffer types (no overload exists in ast_util.h, only in ast.h for m.mk_and)
- Verified build succeeds and Z3 works correctly

* Fix test files to use correct mk_and/mk_or overloads
Changed test/doc.cpp and test/udoc_relation.cpp to use mk_and(expr_ref_vector) and mk_or(expr_ref_vector) without m parameter

* Initial plan
* Update z3 codebase to use std::string_view (except z3++.h)
- Updated params.cpp/h to use string_view internally for parameter descriptions
- Updated trace.h/cpp to accept string_view for trace tag functions
- Updated hash.h/cpp to use string_view for string_hash function
- Updated all callers of string_hash to use string_view
- Properly handled nullptr to empty string_view conversions
- All tests passing

* Add missing string_view includes to headers

Issue #7502 shows that running nlsat eagerly during final check can block quantifier instantiation.
To give space for quantifier instances we introduce two levels for final check such that nlsat is only applied in the second and final level.
the SAT model converter is applied by m_solver.get_model()
Calling m_sat_mc->flush_smc causes the SAT model converter to be inherited within m_sat_mc and then the model converter gets applied again. This time breaking the model.
flush_smc is reserved for incremental use:
Suppose a user propagator encodes axioms using quantifiers and uses E-matching for instantiation. If it wants to implement a custom priority scheme or drop some instances based on internal checks it can register a callback with quantifier instantiation
* Introduce X-macro-based trace tag definition
- Created trace_tags.def to centralize TRACE tag definitions
- Each tag includes a symbolic name and description
- Set up enum class TraceTag for type-safe usage in TRACE macros
* Add script to generate Markdown documentation from trace_tags.def
- Python script parses trace_tags.def and outputs trace_tags.md
* Refactor TRACE_NEW to prepend TraceTag and pass enum to is_trace_enabled
* trace: improve trace tag handling system with hierarchical tagging
- Introduce hierarchical tag-class structure: enabling a tag class activates all child tags
- Unify TRACE, STRACE, SCTRACE, and CTRACE under enum TraceTag
- Implement initial version of trace_tag.def using X(tag, tag_class, description)
(class names and descriptions to be refined in a future update)
* trace: replace all string-based TRACE tags with enum TraceTag
- Migrated all TRACE, STRACE, SCTRACE, and CTRACE macros to use enum TraceTag values instead of raw string literals
* trace : add cstring header
* trace : Add Markdown documentation generation from trace_tags.def via mk_api_doc.py
* trace : rename macro parameter 'class' to 'tag_class' and remove Unicode comment in trace_tags.h.
* trace : Add TODO comment for future implementation of tag_class activation
* trace : Disable code related to tag_class until implementation is ready (#7663).
