## CORE PROBLEM

AI agent sessions hit context window limits and "respawn" -- losing state, agents, rapport, momentum. How do we create frictionless, seamless continuity so the user NEVER sees the seams? What if we modeled session memory like the immune system -- with rapid innate responses, precise adaptive memory, and decades-long recall from a single exposure?

## PARADIGM: IMMUNOLOGY AND ADAPTIVE IMMUNITY

The human immune system performs a miracle: after ONE exposure to chickenpox at age 5, your body remembers it for 80+ years. If chickenpox returns when you're 85, your immune system recognizes it in MINUTES and mounts a precise response.

How does biological memory work?

1. **Two-tier architecture**: Innate immunity (fast, generic) + Adaptive immunity (slow, precise)
2. **Memory cells**: B-cells and T-cells persist for decades after infection resolves
3. **Clonal selection**: Amplify best-fit antibodies, discard poor matches
4. **Antibodies**: Y-shaped proteins that recognize specific antigens (lock-and-key)
5. **Antigen presentation**: Display fragments of threats to activate immune response
6. **Somatic hypermutation**: Antibodies evolve to better match targets
7. **Immune tolerance**: Learn to NOT attack self (distinguish signal from noise)
8. **Cytokine signaling**: Chemical messengers coordinate immune response

## IMMUNOLOGICAL CONCEPTS APPLIED TO SESSIONS

### Innate vs Adaptive Memory
- **Innate** (Redis, <100ms): Last session's state, active mission, current blockers. Fast, generic, ephemeral.
- **Adaptive** (PostgreSQL + Qdrant, <3s): ALL decisions across ALL sessions, Knowledge Graph relationships, historical patterns. Slow, precise, indefinite.

### Memory Cells
After a decision is made, a small "memory cell" persists. Decades later, when a similar query arrives, it responds 100-1000x faster than computing from scratch.

### Clonal Selection
Multiple facts about pricing compete. Score by recency, confidence, reference count. Amplify winners, suppress losers. Darwinian selection for memories.

### Antibodies as Pattern Matchers
Variable region (embedding vector for semantic matching) + binding sites (keywords) + constant region (metadata). Hybrid recognition: 70% semantic + 20% keyword + 10% metadata.

### Somatic Hypermutation
Memory cells evolve over time. Generate variations, test against historical queries, keep improvements, discard regressions. Memories get BETTER with age.

### Immune Tolerance
Distinguish signal (important decisions) from noise (casual chat). Only important events create memory cells. Prevents memory pollution.

### Cytokine Cascade
One recall triggers related recalls automatically. "Stripe blocker" activates -> payment integration -> webhook -> API key. Spreading activation.

## THE IMMUNOLOGICAL QUESTIONS (ANSWER ALL 10)

### 1. Two-Tier Architecture
How do we implement fast innate + slow adaptive memory tiers? Design the innate layer (Redis, <100ms, mission/agents/blockers/recent decisions) and adaptive layer (PostgreSQL + Qdrant, <3s, all decisions/relationships/patterns). Session startup loads innate immediately, then queries adaptive.

### 2. Memory Cell Lifecycle
How do we create, activate, maintain, and retire memory cells? Creation on significant events. Activation on matching queries. Maintenance via periodic refresh and hypermutation. Retirement if activation_count=0 for 90 days.

### 3. Clonal Selection Algorithm
How do we amplify best-fit memories and suppress poor matches? Score candidates, amplify top matches (store in multiple systems, increase affinity), suppress poor matches (remove from cache, decrease affinity).

### 4. Antibody Design
How do we design efficient pattern matchers? Variable region (768-dim embedding), binding sites (keywords), constant region (metadata). Combined scoring: 70% cosine similarity + 20% keyword Jaccard + 10% metadata filter.

### 5. Antigen Presentation Pipeline
How do we automatically extract key concepts from sessions? LLM extraction of key phrases. For each, check if memory exists (activate) or create new memory cell (learn). Runs as background agent post-session.

### 6. Somatic Hypermutation Engine
How do we evolve memories over time? Nightly: generate 10 variants per active cell, test against historical queries, replace with best variant if improvement found. Continuous improvement.

### 7. Signal vs Noise Classification
How do we train immune tolerance? Train classifier on labeled examples (signal vs noise). Features: event type, confidence, word count, contains numbers, sentiment magnitude. Only signal creates memories.

### 8. Cytokine Cascade Implementation
How do we implement associative recall via signal propagation? Spreading activation from initial antigen through Knowledge Graph. Each hop multiplies activation by relationship strength. Stop at depth 3 or strength < 0.3.

### 9. Memory Consolidation (Sleep Phase)
How do we consolidate memories between sessions? Nightly: extract antigens from completed session, create/update cells, run hypermutation, prune weak cells, rebuild Knowledge Graph edges. Like REM sleep.

### 10. Vaccine-Like Preloading
How do we "vaccinate" sessions with critical knowledge before first exposure? When starting new project, extract key concepts from research docs, create memory cells upfront with moderate affinity. Start with learned immunity, no cold start.

## SUCCESS METRICS

1. Decades-long recall: Session 1 decisions retrievable in Session 100 (<3s)
2. Two-tier speed: Innate (<100ms) + Adaptive (<3s)
3. Clonal selection: Best-fit memories dominate
4. Pattern recognition: Antibodies match semantically
5. Automatic learning: New concepts trigger memory cell creation
6. Evolutionary improvement: Hypermutation improves memories over time
7. Signal/noise distinction: Only important events stored
8. Associative cascade: One recall triggers related recalls
9. Nightly consolidation: Background strengthening/pruning
10. Knowledge preloading: No cold start for new projects
