9d674404c8 Add action/expectation/result structure to all skill definitions 
Each step in every SKILL.md now carries labeled Action, Expectation,
and Result blocks so the agent can mechanically execute, verify, and
branch at each stage. Format chosen after comparing three variants
(indented blocks, inline keywords, tables) on a prove-validity
simulation; indented blocks scored highest on routing completeness
and checkability.

d349b93d1d Add Copilot skill architecture with 10 skills, 2 agents, and shared infra 
Introduce .github/skills/ with solve, prove, optimize, simplify,
encode, explain, benchmark, memory-safety, static-analysis, and
deeptest skills. Each skill follows a SKILL.md + scripts/ pattern
with Python scripts backed by a shared SQLite logging library
(z3db.py). Two orchestrator agents (z3-solver, z3-verifier) route
requests to the appropriate skills.

123bb620d4 Add ASan/UBSan memory safety CI workflow 
Adds a workflow that builds and tests Z3 with AddressSanitizer and
UndefinedBehaviorSanitizer on every push to catch runtime memory errors
and undefined behavior. Runs unit tests, SMT-LIB2 benchmarks, and
regression tests under both sanitizers. Includes a Copilot agentic
workflow to generate summary reports as GitHub Discussions.

Triggered on push (path-filtered to src/) and manual dispatch.

93ac330864 Fix assertion violation in q_mbi diagnostic output 
The IF_VERBOSE(0,...) block at line 498 in q_mbi.cpp used operator[]
on values2root map which asserts the key exists. When the model
evaluation of the inverted term produces a value not present in the
EUF values2root map, this crashes.

Use find() instead to handle the missing key gracefully, since this
is diagnostic output and the missing key is expected when the model
inversion produces inconsistent results.

Fixes assertion violation from #7027 (obj_hashtable.h line 168/174)
with forall/array/eq2ineq combination.

fc6696c5e4 Fix memory leaks in model_based_opt def ref-counting 
Three bugs in the def ref-counting infrastructure:

1. dec_ref() incremented (++) instead of decrementing (--) the ref count,
   so objects were never freed.

2. def_ref lacked copy and move constructors, so the compiler-generated
   default copy just copied the raw pointer without inc_ref. This caused
   use-after-free when def_ref values were copied into vectors.

3. Compound def types (add_def, mul_def, div_def) lacked destructors to
   dec_ref their children. Added virtual destructor to base def class
   and child-releasing destructors to compound types.

Fixes the memory leak from #7027 (model_based_opt.cpp:81).

2dac76d19a Handle overflow predicates in new core bit-vector internalization 
Add internalize_overflow() to handle OP_BUMUL_OVFL, OP_BSMUL_OVFL,
OP_BUADD_OVFL, OP_BSADD_OVFL, OP_BUSUB_OVFL, OP_BSSUB_OVFL,
OP_BSDIV_OVFL, and OP_BNEG_OVFL in the sat.euf=true solver path.

Previously these overflow predicates hit UNREACHABLE() in
internalize_circuit(). Now they are reduced to equivalent expressions
using existing BV operations and internalized via add_def().

Fixes the assertion violation from #7027 for bvuaddo and related
overflow predicates with tactic.default_tactic=smt sat.euf=true.
