fragility-engine 0.4.0

Summary

Charter-scope release for the Fragility Discovery Engine: five reference domains, frozen benchmark harness (benchmark-manifest-v2), and publication tooling (Phase L).

Highlights

• Phase N: liquidity_ladder domain, bundle liquidity_ladder_rollout_v1, joint attribution, counterfactual parity
• Institutional composite v4 (penta): five-domain audit JSON + bundled sample + viewer preset
• Benchmark regression: integral, attack_cost, and collapsed-expect floors on frozen bundles
• Manifest CI parity: runtime-independent manifest_summary_sha256 digest
• Docs: docs/README.md hub, docs/PROJECT_STATUS.md
• Tests: 471 pytest cases; 110+ CLI subprocess smokes
