OpenCrab Ontology Pilot — P0-brainstem Schema Implementation

Date: 2026-05-20 Status: Phase 1 Complete Source: AlexAI-MCP/OpenCrab

Background: What is OpenCrab

OpenCrab은 MetaOntology OS의 public integration repository이다. LocalCrab(로컬 온톨로지 팩토리) + OpenCrab SaaS(에코시스템 배포)로 구성된다.

핵심 개념: 9 Space Ontology — 모든 노드를 semantic space로 분류하여 그래프 구조를 형성한다.

OpenCrab 9-Space

SpaceRole
subjectActors with identity, agency, roles, permissions
resourceDocuments, datasets, tools, APIs, files, projects
evidenceRaw observations, logs, text units, parser/OCR outputs
conceptEntities, concepts, topics, classes, domain abstractions
claimDerived assertions grounded by evidence
communityClusters and summaries of related concepts or actors
outcomeKPIs, risks, impacts, measurable results
leverTunable controls that affect outcomes or concepts
policyAccess, sensitivity, approval, governance rules

핵심 도구 (MCP Tools)

  • ontology_manifest — grammar 전체 반환
  • ontology_add_node — grammar 검증된 노드 추가
  • ontology_add_edge — grammar 검증된 엣지 추가
  • ontology_query — hybrid vector + BM25 + graph query
  • ontology_impact — I1-I7 impact analysis
  • ontology_rebac_check — relationship-based access check
  • ontology_ingest — local ontology store에 텍스트 ingestion
  • harness_promotion_apply — CrabHarness promotion package 적용

Drewgent Pilot: What Was Applied

Phase 1 (완료 — 2026-05-20)

P0-brainstem의 .neuron 파일 14개에 typed frontmatter schema 도입:

---
title: 禁{rule_name}
type: policy
space: policy
rule_token: {token_name}
rule_priority: P0 (HIGHEST)
rule_source: {source}
created: 2026-05-20
updated: 2026-05-20
promotion_status: validated
links:
  - "[[P0-brainstem/brain/rules]]"
  - "[[P5-ego/SELF_MODEL]]"
  - "[[P0-brainstem/brain/Drewgent-brain/P0-brainstem/禁/禁brain_obsidian_graph]]"
---

적용된 파일 (14개)

Group A (10개): P0-brainstem/brain/Drewgent-brain/P0-brainstem/

  • 禁auto_validate.neuron
  • 禁blind_write.neuron
  • 禁console_log.neuron
  • 禁filesystem_truth.neuron
  • 禁karpathy_coding_principles.neuron
  • 禁rm_rf_root.neuron
  • 禁secrets_in_code.neuron
  • 禁subagent_verify.neuron
  • 禁task_qa_gate.neuron
  • 禁tool_integration_3file.neuron

Group B (4개): P0-brainstem/brain/Drewgent-brain/P0-brainstem/禁/

  • 禁brain_obsidian_graph.neuron
  • 禁kanban_hallucination.neuron
  • 禁kanban_worker_accountability.neuron
  • 禁task_qa_gate.neuron

rules.md 업데이트 (links 확장, promotion_status 추가)

Graph Export

P0-brainstem/p0-brain-ontology.jsonl — 14개 노드의 그래프 표현:

{"id": "禁rm_rf_root", "type": "policy", "space": "policy", "title": "禁rm_rf_root", "file": "brain/Drewgent-brain/P0-brainstem/禁rm_rf_root.neuron", "links": ["P0-brainstem/brain/rules", "P5-ego/SELF_MODEL", "P0-brainstem/brain/Drewgent-brain/P0-brainstem/禁/禁brain_obsidian_graph"], "rule_priority": "P0 (HIGHEST)", "rule_source": "NeuronFS Governance Defaults"}

Bidirectional Linking 검증

  • 모든 .neuron → rules (hub), SELF_MODEL, 禁brain_obsidian_graph 연결
  • rules.md → 12개 wikilink (.neuron 14개 참조, 중복 제외 12개 고유)
  • orphan .neuron: 0개

space 분류 (현재)

Drewgent Pilot Phase 1에서는 모든 P0 규칙을 space: policy로統一.

향후 확장을 위해 제안된 분류:

  • space: policy — 금지/강제 규칙 (禁*)
  • space: concept — 원칙/가이드 (karpathy_coding_principles)
  • space: evidence — QA 증거/로그 (qa-evidence)
  • space: resource — 도구/스킬 정의
  • space: claim — rules.md (규칙 인덱스)

Phase 2: 완료된 작업 (전체 vault로 확장)

Phase 2-A: 9-Space 확장 ✅ 완료

규칙을 semantic space로 세분화 완료:

  • 禁karpathy_coding_principles → space: concept
  • 禁task_qa_gate (2개) → space: evidence
  • 나머지 11개 → space: policy

전체 vault (P0-P6 + skills + memories 등): 5,014개 노드 중 5,013개 (99.98%) space: 보유

Phase 2-B: ontology_query tool ✅ 완료

P4-cortex/scripts/ontology_query.py + skills/brain/ontology-query/SKILL.md 생성됨.

8개 명령: list, spaces, rule, links, graph, search, orphans, space

Phase 2-C: ReBAC enforcement ✅ 완료

  • 禁rebac_integration — INTEGRATION_PROTOCOL 참조 없이 tool/skill 통합 시 awareness.integrity event
  • 禁rebac_kanban — KANBAN_INDEX 참조 없이 kanban 작업 시 awareness.integrity event
# 예: 禁karpathy_coding_principles
space: concept  # 원칙/가이드
 
# 예: 禁rm_rf_root
space: policy  # 금지 규칙 (유지)
 
# 예: 禁task_qa_gate
space: evidence  # QA 증거/프로세스

Phase 2-B: ontology_query tool (선택)

JSONL 기반 그래프 쿼리:

  • space:policy인 모든 규칙 조회
  • 특정 rule_token으로 노드 조회
  • links 기반 그래프 탐색

Phase 2-C: ReBAC enforcement (선택)

OpenCrab의 relationship-based access check 패턴 적용:

  • 禁tool_integration_3file → INTEGRATION_PROTOCOL 참조 시에만 도구 추가 허용
  • 禁kanban_* → KANBAN_INDEX 참조 시에만 kanban 작업 허용

Verification Checklist

# 1. 모든 .neuron에 frontmatter 존재
find ~/.drewgent/P0-brainstem -name "*.neuron" | wc -l
# → 14 (Group A 10 + Group B 4)
 
# 2. 모든 .neuron에 space: 필드 존재
grep -l "space:" ~/.drewgent/P0-brainstem/brain/Drewgent-brain/P0-brainstem/*.neuron | wc -l
# → 10
 
# 3. orphan .neuron 없음
for f in ~/.drewgent/P0-brainstem/brain/Drewgent-brain/P0-brainstem/*.neuron; do
  grep -q '\[\[' "$f" || echo "ORPHAN: $f"
done
# → (출력 없음)
 
# 4. JSONL 라인 수
wc -l ~/.drewgent/P0-brainstem/p0-brain-ontology.jsonl
# → 14
