v0.19.1

Zero-Drift Gating (Topological Entropy Guardrails)

This release introduces a configuration-free invariant gate that rejects agent plans which mathematically degrade repository modularity.

Added

• Topological Delta Core (src/analyze/delta.rs) — partitions physical and virtual subgraphs, computes Louvain modularity deltas (ΔQ), profiles surprise edges, and detects community drift
• evaluate_delta_gate MCP tool — in-memory modularity delta checks and surprise analysis for real-time design validation
• gm check --delta — CLI topological entropy gate with --plan, --mod-tolerance (default: -0.02), and --surprise-threshold (default: 5.0)
• Zero-config fallback in validate_plan — runs explicit .graphenium/policy.json rules when present, then Dynamic Delta Gating as invariant fallback
• Policy gates banner in graph_info — reports active containment layers at handshake

Changed

• validate_plan (MCP) now runs policy rules and dynamic delta gating in sequence
• Agent skill updated with evaluate_delta_gate guidance and topological delta failure resolution
• install.sh installs the Claude Code skill on Unix installs
• Documentation updated across CLI, MCP, CI, architecture, trust model, and onboarding guides

Graphenium v0.16.1: Audit fixes — Stack Graphs wiring, Datalog exposure, hub filtering

v0.16.1 fixes 6 reachability issues identified in the post-launch audit:

• Stack Graphs wiring: resolve_cross_file_calls() now runs during gm run (not just tests), creating real cross-file edges with 4 types (TRANSITIVE_CALL, EXPORT_MAPPING, IMPORT_SYMBOL, CROSS_MODULE_CALL)
• Datalog exposure: run_datalog MCP tool registered + --datalog CLI flag added to gm query
• OpenTelemetry CLI: observe subcommand with trace import and overlay
• Version: Bumped from 0.15.5 to 0.16.1
• Namespace hub filtering: god_nodes and architecture_summary now filter out aggregation hubs
• PCH hub suppression: ratio and diversity heuristics in hub detection

Full audit: Graphenium-v0.16.0-Reachability-Audit.md
363 tests pass, 0 clippy errors, formatting clean.
