0.1.0 (Unreleased)¶

Initial release.

Sandbox (mass-radius) dimension estimation via estimate_sandbox_dimension
Quality gate chain: R², AICc model selection, curvature guard, slope stability
Machine-readable refusal codes via Reason enum
Post-hoc quality gate via sandbox_quality_gate with inclusive and strict presets
Bootstrap confidence intervals for dimension and delta AICc
Graph type with add_node/add_edge API (zero dependencies)
CompiledGraph frozen dataclass for deterministic BFS
Helper constructors: make_grid_graph, make_path_graph
Degree-preserving rewiring null model
Calibration against (u,v)-flower networks with exact analytical dimensions
Full audit trail in SandboxResult frozen dataclass (25 fields)
Zero runtime dependencies, Python 3.12+

BFS mass computation refactored to layer counts with prefix sums (~2x speedup)
Documentation site built with Zensical (Diataxis framework, 14 content pages, MathJax)
204 tests passing across Python 3.12 and 3.13
