jordan d3a88585fe feat: Phase 6 UAT - Admission control, HLC recency, cluster coordination
This commit includes comprehensive work on Phase 6 features:

## Admission Control (Phase 6 admission middleware)
- AdmissionStore implementation backed by TrustRankStore
- PoW verification with tier-based difficulty computation
- Trust tier progression (Newcomer → Established → Trusted → Authority)
- API integration with admission status endpoints

## HLC Recency Lens (Phase 6C)
- HlcRecencyLens for distributed system ordering
- Hybrid logical clock integration with causality preservation

## Cluster Coordination (Phase 6C)
- Multi-node cluster tests (availability, partition tolerance)
- CRDT convergence tests for anti-entropy sync
- Gateway handler improvements

## Aphoria Code Linter (Phase 2A)
- RFC/OWASP corpus builders with network fetching and caching
- Concept hierarchy with auto-alias creation on conflict detection
- Multiple security extractors (TLS, JWT, CORS, secrets, rate limiting)

## Code Organization
- Split large files into modules to comply with 500-line limit
- Improved test organization with separate test modules
- Fixed rkyv serialization for EigenTrustState (AgentScore struct)

# Phase 6 UAT Results
**Last Updated:** 2026-02-02
**Confidence:** High
## Summary
Full user acceptance testing of Phase 6 (The Mesh — Distributed Writes). All 67 Phase 6 tests pass, existing functionality verified, new cluster node binary works correctly. Two minor issues found and fixed during testing.
**Key Facts:**
- All Phase 6 crates tested: merkle (16), rpc (5), sync (10), cluster (28), battery11 (8)
- New `stemedb-node` binary demonstrates cluster routing
- Go SDK examples (basic, conflict, skeptic) all pass
- Single-node API and Swagger UI verified working
**File Pointer:** `uat/phase6-distributed-2026-02-02.md`
## Test Coverage
| Area | Tests | Status |
|------|-------|--------|
| stemedb-merkle | 16 | PASS |
| stemedb-rpc | 5 | PASS |
| stemedb-sync | 10 | PASS |
| stemedb-cluster | 28 | PASS |
| battery11 replication | 8 | PASS |
| Validation script | 5 checks | PASS |
| Go SDK examples | 3 | PASS |
## Issues Found & Fixed
1. **swim.rs doc comment** (Low) — Missing blank line, fixed
2. **Health endpoint** (Medium) — Bootstrap node reported unhealthy, fixed to check `joined` only
## New Artifacts
- Binary: `crates/stemedb-cluster/src/bin/node.rs`
- Updated: `quickstart.md` Section 8 (Distributed Mode)
- Report: `uat/phase6-distributed-2026-02-02.md`
