Sprints 46-58 implement the cross-language porting foundation: language-to-IR adapters, equivalence checking, gate validation, legacy ingestion, managed/dynamic families, low-level/logic-actor semantics, debug workflow tooling, AST-native family tools, Rust/CPP raising tools, system-level orchestration, query family, and porting gates. Sprint 59 adds the governance layer (policy packs, review boards, waiver packets, ambiguity triage, decision ledger) with the whetstone_review_porting_decision MCP tool. Also includes: sprint plans 46-130, MCP taskitem pipeline scripts, CLAUDE.md, docs, and full test matrix (steps 689-828). Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
