09339c82ab Fix crashes: avoid re-entering factor_sqf_pp from factor_n_sqf_pp
Calling factor_sqf_pp recursively on Hensel-lifted factors corrupts
shared mutable state in the polynomial manager, m_m2pos, m_som_buffer,
m_cheap_som_buffer, m_tmp1, etc., causing assertion violations:
  - polynomial.cpp:473 id < m_m2pos.size()
  - upolynomial.cpp:2624 sign_a == -sign_b

Use factor_1_sqf_pp/factor_2_sqf_pp for small degrees, push directly
for larger degrees. These don't conflict with the outer call's buffers.

5bae864d6e Address review comments on multivariate factorization
- Fix memory leaks: use scoped_numeral instead of raw numeral for
  evaluation points, ensuring cleanup on exceptions
- Precompute lc_inv before the Hensel lifting loop instead of
  recomputing each iteration
- Use scoped_numeral_vector for eval_vals for consistency with codebase
- Move eval_values and candidate_primes to static constexpr class-level
- Document limitations: single-prime Hensel lifting, contiguous factor
  splits only, pseudo-division lc-power caveat
- Condense Bezout derivation comment to 4-line summary
- Fix README to say Hensel lifting instead of GCD recovery

3e5e9026d8 Implement multivariate polynomial factorization via Hensel lifting
Replace the stub factor_n_sqf_pp (TODO: invoke Dejan's procedure) with a
working implementation using bivariate Hensel lifting:

- Evaluate away extra variables to reduce to bivariate
- Factor the univariate specialization
- Lift univariate factors to bivariate via linear Hensel lifting in Zp[x]
- Verify lifted factors multiply to original over Z[x,y]
- For >2 variables, check bivariate factors divide the original polynomial

Tests: (x0+x1)(x0+2x1)(x0+3x1) now correctly factors into 3 linear factors.
All 89 unit tests pass in both release and debug builds.

996dc72300 Fix assertion violation in isolate_roots for nested calls (#6871)
resultant vanishes during a nested isolate_roots call. The mathematical
invariant that the resultant cannot vanish again after recovery does not
hold in all cases, e.g. with certain nonlinear real arithmetic formulas.

The algebraic_exception propagates cleanly through the nlsat solver and
tactic layers which already catch z3_exception.

Add checkpoint() call in gcd_prs() main loop so polynomial GCD
computation respects rlimit/timeout. Add cancellation callback to
HNF calculation so it can be interrupted when the solver is cancelled.

Implement compute_omit_lc_sector_chain() and compute_omit_lc_section_chain()
following SMT-RAT's OneCellCAD.h logic:
- Omit ldcf for extreme of lower chain (index 0) if it appears on upper side
- Omit ldcf for extreme of upper chain (last index) if it appears on lower side

* Restrict noDisc optimization to section_lowest_degree only

Match SMT-RAT behavior: noDisc (discriminant omission for leaves
connected only to section polynomial) is only applied for
sectionHeuristic == 3 (lowest_degree), not for biggest_cell or chain.

* Cache partition boundary to avoid repeated algebraic number comparisons

Store the partition boundary (index of first root > sample) in
relation_E after sorting root functions. Use this cached value
in compute_omit_lc_sector_chain() and compute_omit_lc_section_chain()
instead of recomputing via algebraic number comparisons.

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

* Refactor levelwise: consolidate partition indices into m_l_rf/m_u_rf

Replace scattered local l_index/u_index parameters and m_partition_boundary
with two impl members:
- m_l_rf: position of lower bound in m_rel.m_rfunc
- m_u_rf: position of upper bound in m_rel.m_rfunc (UINT_MAX in section case)

This simplifies the code by:
- Removing parameter passing through multiple function calls
- Removing redundant m_partition_boundary from relation_E
- Making the partition state explicit in impl

Also clean up nlsat_explain.cpp to trust root_function_interval invariants:
- Section case: assert l and l_index are valid instead of defensive check
- Sector bounds: !l_inf()/!u_inf() implies valid polynomial and index

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

* Refactor levelwise: use member variables for per-level state

Replace local variables and function parameters with member variables:
- m_level_ps: polynomials at current level (owned)
- m_level_tags: tags for each polynomial (owned)
- m_witnesses: non-zero coefficient witnesses
- m_poly_has_roots: which polynomials have roots
- m_todo: pointer to todo_set

Functions now use these member variables directly:
- extract_max_tagged() fills m_level_ps/m_level_tags and sets m_level
- process_level() and process_top_level() are now parameterless
- All helper functions use member variables instead of parameters

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

* Refactor levelwise: change m_todo from pointer to member

- Change m_todo from todo_set* to todo_set
- Initialize m_todo in constructor initializer list
- Use m_todo.reset() in single_cell_work instead of creating local todo_set
- Replace pointer access (m_todo->) with member access (m_todo.)

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

* Add dynamic heuristic selection for levelwise projection

Implement weight-based dynamic selection of projection heuristics in
levelwise CAD. The weight function w(p, level) = deg(p, level) estimates
projection complexity, with w(res(a,b)) ≈ w(a) + w(b).

At each level, all three heuristics (biggest_cell, chain, lowest_degree)
are evaluated and the one with minimum estimated resultant weight is
selected. When fewer than 2 root functions exist, the default heuristic
is used since all produce equivalent results.

Add parameter nlsat.lws_dynamic_heuristic (default: true) to enable or
disable dynamic selection. When disabled, the static heuristic from
lws_sector_rel_mode/lws_section_rel_mode is used.

* Fix nlsat projection bug: ensure polynomials with assumptions are also projected

When polynomials are added as assumptions (via add_assumption or ensure_sign),
they must also be added to the projection set (m_todo) to ensure proper cell
construction. Previously, assumptions were added without corresponding projection,
leading to unsound lemmas.

Fixes:
1. In normalize(): collect lower-stage polynomials in m_lower_stage_polys and
   add them to m_ps in main() before projection.
2. In ensure_sign(): call insert_fresh_factors_in_todo(p) after adding assumption.
3. In project_cdcac(): when levelwise fails, use flet to set m_add_all_coeffs=true
   for the fallback projection.

* Remove deprecated project_original and cell_sample parameter

- Remove project_original() function from nlsat_explain.cpp
- Remove m_sample_cell_project member variable
- Simplify project() to just call project_cdcac()
- Remove cell_sample parameter from nlsat_params.pyg
- Update nlsat_solver.cpp to remove cell_sample() references
- Update nlsat_explain.h constructor signature

* Enforce bound polynomial LC protection in compute_omit_lc functions

Move the invariant that bound-defining polynomials must never have their
LC omitted from add_level_projections_sector() into the source functions:
- compute_omit_lc_both_sides()
- compute_omit_lc_chain_extremes()

This centralizes the protection and removes the redundant override check.

Centralize and document TRACE tags using X-macros (#7657)
* 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).

Care for root index being undefine while calling Z3_algebraic_get_i() (#5888)
In some cases, Z3_algebraic_get_i() returned 0. For example, in the following
Python snippet, the last assert would fail:

    import z3
    x = z3.Real('x')
    s = z3.Solver()
    s.add( (x * x) - 2 == 0, x <= 0)
    s.check()
    val_x = s.model().get_interp(x)
    assert val_x.index() == 1

The problem was that `algebraic_numbers::manager:👿:get_i()` did not
check whether the root index was properly initialized.

This commit fixes this issue by checking whether root index is initialized
the same way various other routines do.

Fixes issue #5807.
