The Ultimate Mathematical & AI Toolkit: Sublinear algorithms, consciousness exploration, psycho-symbolic reasoning, and temporal prediction in one unified MCP interface. WASM-accelerated with emergent behavior analysis.

⚠️ Security posture (1.6.0+): This release closed issue #19 (CWE-73, Arbitrary File Write) in the MCP tools. Every PR is now gated by five supply-chain layers (cargo-audit against RustSec, cargo-deny for license + source + ban policy, npm-audit, GitHub's dependency-review-action, and a lockfile-integrity check) plus the original safe-path regression suite. Dependabot files dep updates as PRs weekly so the gates fire on each one. See CHANGELOG.md for the v1.6.0 breaking-change upgrade guide and BENCHMARK.md for performance numbers.

Every public solver, sampler, and analyser in this crate declares its worst-case complexity class at the type level (Complexity trait, compile-time const CLASS) and at the MCP wire level (x-complexity JSON Schema extension on every tool). Callers with a J/decision budget — Cognitum reflex loops, RuView change detection, Ruflo agentic inner loops — can refuse anything over budget at tool-list time, not after the call returns.

The 12-tier taxonomy (Logarithmic → DoubleExponential, plus Adaptive { default, worst } for solvers that degrade on hard inputs) lives in src/complexity.rs. The decision rationale and full 6-item roadmap is in docs/adr/ADR-001-complexity-as-architecture.md.

Headline classes in v1.7+ (phase-2 primitives shipped):

Empirical receipt (benches/solver_benchmarks.rs::delta_solve, cargo bench -- --quick delta_solve):

cold_full / warm_full grow linearly with n; sparse_closure stays roughly constant (256→1024 is essentially no change in cost). The curves diverge with n — the architectural payoff at scale.

Runtime introspection via dyn ComplexityIntrospect, or mcp__sublinear__estimateComplexityClass over the wire (now covers every phase-2 method name: closure-indices, solve-single-entry-neumann, solve-on-change-sublinear, contrastive-solve-on-change-sublinear, contrastive-solve-on-change). MCP solve, estimateEntry, and solveTrueSublinear all enforce the caller's max_complexity_class budget before any solver work runs — the bounded-planning kernel of ADR-001. Energy numbers (J/solve) — the metric that actually matters on a Pi Zero — captured via examples/joules_per_decision.rs (Linux RAPL / hwmon / time-only fallback).
