# Marketplace Ontology-Guards Transformation: Phase 1 Complete ✅

**Date**: 2025-11-16
**Branch**: `claude/marketplace-ontology-guards-017CPfCsz3gA29MV38F2Lxn9`
**Commits**: d3e757b9 (foundation), 1348c5a0 (plan)
**Status**: Foundation Complete | Phase 2 Ready for Parallel Execution

---

## What Was Asked

> "Treat the marketplace as **O_market** with ggen as **μ_market** and ask: 'What should the swarm change in O and μ so A (packages, flags, receipts) jumps a level in rigor and usefulness?'"

**Translation**: How can we transform the marketplace from a static JSON registry into a formal, audited, guard-enforced substrate?

---

## What Was Built: Phase 1 Foundation

### ✅ O_market: Formal Ontology (`marketplace/ontology.ttl`)

**1,000+ lines of RDF/RDFS/OWL** defining the conceptual model:

#### Core Classes
- **Package**: Deployable marketplace item with metadata, scoring, dependencies
- **Asset**: Deliverables (templates, source, RDF, SPARQL, tests, docs)
- **QualityMetric**: Scoring dimensions
- **Guard**: Validation rules (name, weight, severity, SLO)
- **GuardResult**: Per-guard outcomes
- **ValidationReceipt**: Immutable audit records
- **Bundle**: Vertical collections
- **Dependency**: Package/runtime/version constraints

#### Guard Types Defined
| Guard | Weight | Severity | Purpose |
|-------|--------|----------|---------|
| GuardMetadata | 10 | Critical | Validates `package.toml` completeness |
| GuardLicense | 8 | Critical | Validates license file presence |
| GuardReadme | 7 | Critical | Validates README quality |
| GuardSrc | 9 | Critical | Validates source code presence |
| GuardTests | 8 | Critical | Validates test suite |
| GuardTemplates | 6 | Bonus | Validates reusable templates |
| GuardRdf | 5 | Bonus | Validates RDF/ontology |
| GuardSparql | 4 | Bonus | Validates SPARQL queries |
| GuardDocs | 5 | Bonus | Validates documentation |
| GuardChicagoCompliance | 15 | Critical | Validates Chatman Equation patterns |

### ✅ μ_market: Rust Guard System (`crates/ggen-domain/src/marketplace/guards.rs`)

**700+ lines of production-grade Rust**:

#### Core Types

**Guard Trait** — Abstract validation rule:
```rust
pub trait Guard: Send + Sync {
    fn id(&self) -> &str;
    fn name(&self) -> &str;
    fn severity(&self) -> Severity;  // Critical | Bonus
    fn weight(&self) -> u32;
    fn execute(&self, package_path: &Path) -> GuardResult<GuardCheckResult>;
}
```

**ValidationReceipt** — Immutable audit record:
- Package ID, version, validation timestamp
- Guard results (passed/failed per guard)
- Overall score (0-100)
- Production ready flag
- SHA256 checksum for immutability

**Storage**: `marketplace/receipts/<package_id>/<version>.json`

#### Standard Guards Implemented
- GuardMetadata: Checks package.toml completeness
- GuardLicense: Validates license files
- GuardReadme: Checks README presence and length (≥500 chars)
- GuardTests: Validates test directory or files

### ✅ Documentation & Architecture

**`marketplace/ONTOLOGY_GUARDS_ARCHITECTURE.md`** (450+ lines):
- Complete O → μ → A transformation model
- Guard system design and scoring algorithm
- Phase 2 parallel tracks breakdown
- Integration with Chatman Equation

**`marketplace/SWARM_EXECUTION_PLAN.md`** (430+ lines):
- 6 parallel work tracks (A-F) with effort estimates
- Code entry points and dependencies
- Definition of done per track
- Parallelization strategy (2-3 teams, 2-3 weeks)

---

## Scoring Algorithm

```
final_score = (Σ guard_weight × guard_passed) / (Σ all_guard_weights) × 100

production_ready = (all_critical_guards_pass) AND (final_score ≥ 95.0)
```

**Critical path**: All guards weighted and prioritized by importance

### Track C: Quality Autopilot
- Guard infrastructure ready ✅
- Just needs CLI command
- **Est. 4-5 hours**

### Track D: Chatman Integration
- Guard trait ready ✅
- Just needs GuardChicagoCompliance implementation
- **Est. 3-5 hours**

### Track E: Sector Bundles

## Next Actions

**For the swarm**:

1. **Read** `marketplace/SWARM_EXECUTION_PLAN.md` — detailed breakdown of 6 tracks
2. **Pick a track** — recommend starting with Track A (critical path)
3. **Code entry points** — listed in execution plan per track
4. **Test on 55 packages** — existing marketplace as test bed
5. **Commit to branch** — `claude/marketplace-ontology-guards-017CPfCsz3gA29MV38F2Lxn9`

**Timeline**: 2-3 weeks for full Phase 2 with coordinated team
