Vitte Roadmap 161-200: Execution Plan by Quarter

Planning assumptions

  • Horizon: 8 quarters (24 months), with rolling re-baseline every quarter.
  • Rule: no milestone closes without tests, diagnostics quality checks, and updated docs.
  • Governance gate: added complexity must remain below reliability confidence gained.

Quarter-by-quarter plan

Q1 - Type safety core hardening

Scope:

  • 161 Advanced Type Inference
  • 162 Generics Foundation
  • 164 Trait / Interface Foundation (minimal)
  • 166 Advanced Pattern Matching
  • 167 Exhaustiveness Engine
  • 188 Unsafe Code Model (baseline policy)

Exit criteria:

  • typing soundness regressions: 0
  • exhaustive match checks enabled on stable surface
  • unsafe diagnostics available with explicit spans

Q2 - Expressiveness without trust erosion

Scope:

  • 163 Generic Monomorphization
  • 165 Dynamic Dispatch Support
  • 168 Const Generics Foundation
  • 169 Macro System Foundation
  • 170 Macro Expansion Pipeline

Exit criteria:

  • deterministic specialization cache behavior
  • object safety checks in dyn dispatch
  • macro expansion keeps source-level diagnostics fidelity

Q3 - Async and concurrency semantics

Scope:

  • 171 Async Foundation
  • 172 Coroutine Lowering
  • 173 Concurrency Memory Model
  • 174 Parallel Borrow Analysis

Exit criteria:

  • async lowering correctness suite green
  • concurrency model published and versioned
  • thread-safety diagnostics integrated in CI

Q4 - Performance and machine correctness

Scope:

  • 175 Advanced Optimization Passes
  • 178 Register Allocator
  • 179 Low-level ABI Test Suite
  • 181 MIR Interpret

Exit criteria:

  • measurable benchmark gains on reference corpus
  • ABI suite passing on primary targets
  • MIR interpreter usable for debug/repro workflows

Q5 - Backend expansion and execution modes

Scope:

  • 176 LLVM Backend Experimental
  • 177 Native ASM Backend
  • 180 JIT Foundation

Exit criteria:

  • experimental backends isolated behind feature flags
  • ABI parity checks defined per backend path
  • JIT path operational on constrained subset

Q6 - Developer platform maturity

Scope:

  • 182 Compiler Embedding API
  • 183 IDE Integration Complete
  • 184 Refactor Engine
  • 185 Advanced Formatter

Exit criteria:

  • embedding API with stable callback contracts
  • IDE diagnostics incremental pipeline usable at scale
  • formatter deterministic across repeated runs

Q7 - Analysis, security, runtime/interop targets

Scope:

  • 186 Static Analysis Framework
  • 187 Security Analysis Passes
  • 189 Verified Unsafe Boundaries
  • 190 Advanced Runtime Services
  • 192 Foreign Function Interface
  • 193 Bindgen Foundation

Exit criteria:

  • baseline security checks integrated in release gate
  • unsafe audit trail generated and reviewable
  • FFI ABI mismatch diagnostics validated on fixtures

Q8 - Long-term confidence and platform completion

Scope:

  • 191 GC Experimental Mode
  • 194 Embedded Target Support
  • 195 Kernel Mode Foundation
  • 196 Compiler Research Sandbox
  • 197 Verified Compiler Pipeline
  • 198 Formal Semantic Model
  • 199 Vitte Language Platform
  • 200 Vitte Platform Complete Foundation

Exit criteria:

  • formal model baseline published
  • verified-pipeline checks active in CI
  • platform checklist for 200 reviewed and signed off

Ongoing every quarter

  • Reliability KPIs: soundness, determinism, crash-free compile rate.
  • Docs sync: architecture, diagnostics, and status pages aligned with shipped behavior.
  • Risk review: complexity budget reviewed at each quarterly close.
