Milestone: Milestone 12 — Advanced Symbolic Reasoning & Z3 Integration (Phase 2)
Bullet:

bench/smt-bench.md — SMT solver performance baseline: run 50 constraint problems of varying complexity (linear arithmetic, bitvector operations, array operations) across Z3, CVC5, and Yices2; output comparison table of solve time and memory usage

Implementation note: Files marked "new (does not exist yet)" must be created from scratch. verify-first should return PROCEED (not NOT_YET) — there is no prerequisite blocking this work.

Acceptance criteria

• Command test -s bench/smt-bench.md passes
• The specific work described in the bullet above is implemented in the smallest number of files required.
• No unrelated files touched (git status --short output limited to the intended change).

Notes for the implementer

This issue was auto-created by SweepMilestoneBulletToIssue. The bullet text is verbatim
from the milestone doc. If ambiguous or too large for a single implement cycle,
verify-first should return NEEDS_SPLIT with sub-issue proposals or NEEDS_HUMAN with the blocker.
