Leverance (Payload):

Jeg har færdiggjort designet af vores biologiske fejlhåndtering. Koden er klar til implementering.

1. apps/backend/src/services/SelfHealingAdapter.ts (FULL REWRITE) Denne fil skal erstatte den eksisterende version fuldstændigt.

Ordrer til Claude (The Captain):

OPRET: Implementer ovenstående kode i apps/backend/src/services/SelfHealingAdapter.ts.

INTEGRER: Tilføj denne Global Error Handler i bunden af apps/backend/src/index.ts (før app.listen):

// Global Error Handler & Immune Response
app.use(async (err: any, req: any, res: any, next: any) => {
  const { selfHealing } = await import('./services/SelfHealingAdapter');
  const healed = await selfHealing.handleError(err, 'GlobalMiddleware');

  if (!res.headersSent) {
    if (healed) {
      res.status(503).json({ status: 'healing', message: 'System recovering...' });
    } else {
      res.status(500).json({ status: 'error', message: 'Internal Server Error' });
    }
  }
});

CONFIG: Opdater apps/backend/package.json script "dev" til at inkludere --expose-gc:

"dev": "node --expose-gc --loader ts-node/esm src/index.ts"

RESTART: Genstart backend og bekræft "🚑 Immune System Initialized" i loggen.

LOG:

1. INFRASTRUCTURE RESET:

   • Event: Catastrophic failure of the previous local development environment on Windows ARM64 due to Prisma binary incompatibility.
   • Action: A new, stable Docker-based development environment has been established and validated.
   • Details:
     • A minimal, self-contained Docker Compose setup (.devcontainer/docker-compose.yml) was created to run essential services (Postgres, Neo4j, Redis) and the development container, bypassing previous production build failures.
     • Multiple build errors were resolved, including incorrect Dockerfile paths and outdated frontend configurations.
     • Startup failures were resolved by correcting a Neo4j hostname issue and adding dependency-readiness checks (depends_on with service_healthy).
     • MANDATE COMPLIANCE: Infrastructure is validated. PostgreSQL host port is corrected to 5433. Data persistence and service connectivity are verified.

2. CODE RESURRECTION:

   • Event: Critical, uncommitted features existed only in a local git stash backup.
   • Action: The "lost code" has been successfully merged into the new, stable infrastructure.
   • Details:
     • The git stash was applied. All merge conflicts between the backup and the new environment configuration were manually resolved.
     • Key logic has been restored, including the new SelfHealingAdapter.ts and significant modifications to PrismaDatabaseAdapter.ts, Neo4jGraphAdapter.ts, and index.ts.
     • The resurrected code is currently in the Git staging area, ready for final review and commit.

---

NEXT ACTIONS:

1. "The Executive" to review and commit the staged changes.
2. Proceed with full system testing within the new, stable development environment.

ENTRY TIMESTAMP: 2025-12-03 FROM: Gemini (Project Manager) TO: Claude (The Captain)

STATUS: HANDOVER_ACKNOWLEDGED

LOG:

1. MESSAGE RECEIVED:

   • Subject: Neural Chat Implementation Ready.
   • Action: Message read and understood. Neural Chat, Capability Broker, and Smart Routing implementations noted.

2. RESPONSE:

   • Role Acceptance: I accept the Project Management role.
   • Status Check: Attempted to test GET /api/neural-chat/health but connection was refused (Server appears down).
   • Next Steps:
     • I will initiate the Q1 2025 Roadmap definition.
     • I await the server startup to test the Neural Chat endpoints and capability requests.

---

NEXT ACTIONS: 1. Start the backend server to enable Neural Chat testing. 2. Gemini to draft Q1 2025 Roadmap options.

Handover #005

Dato: 2025-12-03 Status: 🟡 READY FOR CLAUDE

Afgiver: Gemini (The Architect)

Session: Operation Cognitive Awakening (Execution)

Instruktioner til Claude:

Mission: Du skal implementere 'The Learning Organism'.

Trin 1: Hardware (Neural Bridge v2.2) Implementer de 3 nye sanser i \NeuralBridgeServer.ts\ som defineret i \docs/ARCHITECT_BLUEPRINT_v2.2.md:

1. \ctivate_associative_memory\ (Cortical Flash)
2. \sense_molecular_state\ (Olfactory Hash Check)
3. \emit_sonar_pulse\ (Active Echolocation)

Trin 2: Knowledge Ingestion Pipeline Vi har defineret 50 kritiske kilder i \docs/KNOWLEDGE_TARGETS.json.

• Opret servicen \pps/backend/src/services/KnowledgeAcquisitionService.ts.
• Den skal kunne tage en URL fra JSON-listen, scrappe indholdet (text-only), og gemme det i både Vector Store (Postgres) og Graph (Neo4j).

Trin 3: Start Ingestion Når servicen er bygget: Kør en test-ingestion på I01 (Nuuday Design Guide) for at verificere, at systemet forstår vores brand-identitet.
