Complete Entrypoint Detection Re-Engineering Program (Sprints 0410-0415) and Sprint 3500.0002.0003 (Proof Replay + API)
Entrypoint Detection Program (100% complete): - Sprint 0411: Semantic Entrypoint Engine - all 25 tasks DONE - Sprint 0412: Temporal & Mesh Entrypoint - all 19 tasks DONE - Sprint 0413: Speculative Execution Engine - all 19 tasks DONE - Sprint 0414: Binary Intelligence - all 19 tasks DONE - Sprint 0415: Predictive Risk Scoring - all tasks DONE Key deliverables: - SemanticEntrypoint schema with ApplicationIntent/CapabilityClass - TemporalEntrypointGraph and MeshEntrypointGraph - ShellSymbolicExecutor with PathEnumerator and PathConfidenceScorer - CodeFingerprint index with symbol recovery - RiskScore with multi-dimensional risk assessment Sprint 3500.0002.0003 (Proof Replay + API): - ManifestEndpoints with DSSE content negotiation - Proof bundle endpoints by root hash - IdempotencyMiddleware with RFC 9530 Content-Digest - Rate limiting (100 req/hr per tenant) - OpenAPI documentation updates Tests: 357 EntryTrace tests pass, WebService tests blocked by pre-existing infrastructure issue
