# StarForth Roadmap: VM → Kernel → OS → FPGA

> **OBSOLETE (flagged 2026-08-26, Captain Bob's call — this is more than "stale," the
> architecture, branch topology, and terminology it describes no longer exist).** This is a
> StarForth-era plan dated 2025-12-14, written before the repo split, before
> Tripod/Stadium/word-level ACL existed, and before "Phase 1 Starting (HAL)" had any of the
> meaning it has now. Kept for historical record only. For current status, see
> `docs/lithosananke/ROADMAP.md` (repo-specific, LithosAnanke roadmap) and
> `FABRIC.md`/`FABRIC-2.md`/`FABRIC-3.md` (design history and current work) — not this
> document.

**Version**: 1.0
**Date**: 2025-12-14
**Timeline**: 2025-2028 (3.5 years)
**Status**: Phase 0 Complete (VM), Phase 1 Starting (HAL)

## VISION

**From**: Adaptive FORTH VM running on hosted OS (Linux)
**To**: Self-hosting operating system running on custom FPGA hardware

### What We Have

**StarForth VM** - Production-ready adaptive FORTH interpreter:
- ✅ FORTH-79 compliant (780+ tests passing)
- ✅ Adaptive runtime (7 feedback loops, 0% algorithmic variance)
- ✅ Platforms: Linux (HISTORICAL: also L4Re/Fiasco.OC through mid-2026; removed as an active target)
- ✅ Performance: 100M iterations/sec, profile-guided optimization
- ✅ Quality: 9.2/10 codebase rating, strict ANSI C99
- ✅ Validation: Peer-reviewed, 90-run statistical proof
- ✅ Patent pending: Adaptive runtime mechanisms

**Documentation**:
- ✅ 121-page academic paper

- ✅ Reproducibility guarantees
- ✅ CI-ready test suite

### What's Missing

**See**: [docs/GAP_ANALYSIS.md](docs/GAP_ANALYSIS.md) for complete list (37 gaps identified)

**Critical Blockers**:
1. HAL abstraction layer (8 components) - **Blocks everything**
2. StarKernel implementation (13 components)
3. StarshipOS subsystems (12 components)
4. FPGA feasibility & design (19 components)

---

## PHASE 1: HAL IMPLEMENTATION (Months 1-2)

**Goal**: Make StarForth platform-agnostic via Hardware Abstraction Layer

**Why**: HAL is the foundation for all future work. Without HAL, cannot build kernel or port to FPGA.

### Deliverables

| # | Component | LOC | Duration | Status |
|---|-----------|-----|----------|--------|
| 1.1 | Define HAL interfaces (6 headers) | 500 | 1 week | 📋 Planned |
| 1.2 | Implement Linux HAL | 1500 | 2 weeks | 📋 Planned |
| 1.3 | Migrate VM core to HAL | 800 | 2 weeks | 📋 Planned |
| 1.4 | Migrate physics subsystems | 300 | 1 week | 📋 Planned |
| 1.5 | Validate determinism (DoE) | Testing | 2 days | 📋 Planned |

**Total**: ~3,100 LOC, 6-7 weeks

### Success Criteria

- ✅ All HAL interface headers exist (`hal_time.h`, `hal_interrupt.h`, etc.)
- ✅ Linux HAL implementation complete
- ✅ VM core has zero direct platform dependencies
- ✅ All 780+ tests pass on HAL
- ✅ 0% algorithmic variance maintained
- ✅ No measurable performance regression

### Milestones

**Week 2**: HAL headers defined, Linux implementation started
**Week 4**: Linux HAL complete, VM migration started
**Week 6**: All tests passing, determinism validated

**Blocker Risk**: Low (well-understood refactoring)

---

## PHASE 2: STARKERNEL (Months 3-5)

**Goal**: Boot StarForth on bare metal (UEFI → kernel → "ok" prompt)

**Why**: Kernel enables true OS development and demonstrates platform independence.

### Resource Allocation (Solo Development)

**Months 1-5** (HAL + Kernel): 100% focus
**Months 6-7** (Feasibility): 80% OS, 20% FPGA study
**Months 8-18** (Parallel): 70% OS, 30% FPGA (if GO)
**Months 19-24** (FPGA finish): 50% OS, 50% FPGA

**Community Contributions**: Welcomed at all stages (see CONTRIBUTING.md)

## RISK MITIGATION

### High-Risk Items

| Risk | Probability | Impact | Mitigation |
|------|-------------|--------|------------|
| **HAL breaks determinism** | Low | Critical | Extensive testing, DoE validation |
| **Kernel never boots** | Medium | Critical | Incremental dev, QEMU testing |
| **FPGA too slow** | Medium | High | Feasibility study gates investment |
| **Adaptive runtime unsynthesizable** | High | High | Software fallback on ARM core |
| **Project too large (solo)** | High | Medium | Community outreach, phased delivery |
| **FPGA cost too high** | Low | Medium | Target affordable boards ($200-500) |

### Fallback Plans

**If HAL migration fails**: Continue hosted-only, defer kernel
**If OS scope too large**: Deliver minimal components (storage + network only)
**If FPGA infeasible**: Software-only path is still valuable

## CONCLUSION

**This roadmap is ambitious but achievable.**

**Key Success Factors**:
1. ✅ Strong foundation (Phase 0 complete)
2. ✅ Clear milestones (phased delivery)
3. ✅ Risk mitigation (fallback plans)
4. ⚠️ Community growth (critical for timeline)
5. ⚠️ FPGA decision (feasibility gates investment)

**Realistic Timeline**:
- Solo: 3.5 years (42 months)
- With 3-5 contributors: 2 years (24 months)
- With 10+ contributors: 1.5 years (18 months)

**The vision is clear. The path is defined. Now we build.**
