Production-Ready Module
(scored, typed, tested, documented)
Total time: ~2 seconds ⚡
ALGO-37: Planning Depth Expander¶
Score: 10.0 / 10
Tests: 14/14 passed (property-based)
Standard planning algorithms typically generate 3–5 levels of hierarchy. The Planning Depth Expander generates 15 levels — capturing micro-decisions that flat planners miss.
How It Works¶
- Input: High-level goal statement (e.g., "Build a fraud detection API")
- Expansion: Recursively decomposes each goal into sub-goals until all leaf nodes are atomic, executable actions
- Validation: Each expanded plan is validated against FDIA ≥ 0.60 at every level
- Output: A 15-level tree of executable steps with estimated cost and duration at each node
What 15 Levels Enables¶
| Planning Depth | Captured Decisions |
|---|---|
| Levels 1–3 | High-level architecture choices |
| Levels 4–7 | Module and interface design |
| Levels 8–11 | Function-level implementation details |
| Levels 12–15 | Edge cases, error handling, observability hooks |
Most automated planners stop at Level 3–5. Levels 8–15 are where implementation failures originate — and where Tier 9 prevents them.
Code Example¶
from core.tier9.planning_expander import PlanningDepthExpander
expander = PlanningDepthExpander(max_depth=15)
plan = expander.expand(
goal="Build a fraud detection API with FDIA governance",
constraints=["Python 3.12", "FastAPI", "< 50ms p95 latency"],
)
print(f"Total nodes: {plan.node_count}") # → 847 nodes
print(f"Depth reached: {plan.max_depth}") # → 15
print(f"Leaf actions: {plan.leaf_action_count}") # → 312 atomic actions
print(f"FDIA-validated: {plan.all_nodes_pass}") # → True
ALGO-38: CSP Solver¶
Score: 10.0 / 10
Tests: 14/14 passed (all constraint satisfaction edge cases covered)
After the Planning Depth Expander generates the execution tree, CSP Solver verifies that the plan is internally consistent — that no two steps violate each other's preconditions or resource constraints.
Algorithm¶
Implements AC-3 (Arc Consistency Algorithm 3) + Backtracking Search:
1. Model constraints as a Constraint Satisfaction Problem (CSP)
- Variables: every step in the execution plan
- Domains: valid execution states for each step
- Constraints: ordering, resource, mutex constraints
2. Run AC-3 to eliminate impossible states:
- For every constraint arc (Xi, Xj):
- Remove values from Domain(Xi) that no value in Domain(Xj) can satisfy
- If Domain(Xi) changed, re-queue all arcs pointing to Xi
3. If AC-3 detects an empty domain → conflict → backtrack and try alternate
4. Output: conflict-free execution order with guaranteed feasibility
Types of Constraints Handled¶
| Constraint Type | Example |
|---|---|
| Ordering | validate_schema must complete before run_migration |
| Resource mutex | Only one write transaction to DB at a time |
| Capacity | Max 4 parallel API calls to external service |
| Conditional | enable_caching only if response_time > 200ms |
| Anti-pattern | Never run drop_table in the same batch as seed_data |
Code Example¶
from core.tier9.csp_solver import CSPSolver, Constraint, ConstraintType
solver = CSPSolver()
# Define constraints for a deployment plan
solver.add_constraint(Constraint(
type=ConstraintType.ORDERING,
before="run_tests",
after="deploy_to_production",
))
solver.add_constraint(Constraint(
type=ConstraintType.MUTEX,
resources=["production_db_write"],
max_concurrent=1,
))
result = solver.solve(plan=expanded_plan)
print(f"Satisfiable: {result.is_satisfiable}") # → True
print(f"Conflicts resolved: {result.conflicts}") # → 0
print(f"Execution order: {result.ordered_steps}")
ALGO-39: Genesis Engine¶
Score: 9.5 / 10
Output size: 900+ lines of production code per instantiation
Generation time: ~800–1,200ms
The Genesis Engine takes a validated, constraint-free plan from ALGO-37 and ALGO-38 and instantiates a complete, production-ready module — not a skeleton, not a template, but fully scored, typed, documented, and tested code.
What "Production-Ready" Means¶
Genesis Engine output always includes:
| Component | Details |
|---|---|
| Type annotations | Full Python type hints on all public APIs |
| Docstrings | Google-style docstrings with parameter descriptions and examples |
| Unit tests | Property-based test suite using Hypothesis |
| FDIA scoring | Every exported function scored before the file is written |
| Ed25519 signature | Module signed by the Genesis Engine on output |
| Observability hooks | Logging, metrics, and tracing integration points |
Code Example¶
from core.tier9.genesis_engine import GenesisEngine
engine = GenesisEngine()
# Takes the CSP-validated plan from ALGO-37 + ALGO-38
module = engine.instantiate(
plan=validated_plan,
target_language="python",
style_profile="production",
fdia_threshold=0.70, # Higher threshold for production output
)
print(f"Module: {module.name}") # → fraud_detection_api
print(f"Lines of code: {module.loc}") # → 923 lines
print(f"FDIA score: {module.fdia_score:.2f}") # → 0.847
print(f"Tests generated: {module.test_count}") # → 47 tests
print(f"Signature valid: {module.is_signed}") # → True
print(f"Generation time: {module.elapsed_ms}ms") # → 1143ms

ALGO-40: ITSR¶
Full Name: Intent-Driven Tech Stack Recommender
Score: 9.8 / 10
Accuracy: 98.7% correct stack recommendations on held-out test cases
Speed: Reduces architecture decision time from 4 weeks → 10 minutes
ITSR maps a plain-language intent to an optimal, opinionated tech stack — accounting for team size, existing infrastructure, compliance requirements, and performance targets.
Input → Output¶
Input: Plain text description of what the system needs to do Output: A complete, scored, justified technology stack specification
from core.tier9.itsr import ITSRRecommender
recommender = ITSRRecommender()
recommendation = recommender.recommend(
intent="Real-time fraud detection API: "
"10,000 rps, p95 < 50ms, SOC2 compliant, "
"team of 4 Python engineers",
)
print(recommendation.summary())
Output:
Tech Stack Recommendation — FDIA Score: 0.93
============================================
API Layer: FastAPI 0.115 (async, OpenAPI, auto-docs)
ML Runtime: ONNX Runtime 1.18 (< 8ms inference p95)
Database: PostgreSQL 16 + TimescaleDB (time-series fraud logs)
Vector Store: Qdrant 1.11 (< 10ms semantic search)
Cache: Redis 7.4 (< 1ms session lookup)
Queue: Celery + Redis (async investigation jobs)
Observability: OpenTelemetry + Grafana (SOC2 audit trail)
Auth: JWT + Ed25519 (signed JITNA packets)
Rationale:
- FastAPI: native async handles 10k rps with 4-person team maintainability
- ONNX Runtime: eliminates Python GIL on inference hot path
- TimescaleDB: SOC2 audit trail with time-series partitioning built-in
- Qdrant: GraphRAG-compatible vector search for behavioral pattern matching
Estimated time-to-architecture: 11 minutes (vs. 4-week manual assessment)
Recommendation Dimensions¶
ITSR evaluates stacks across 7 dimensions:
| Dimension | What It Measures |
|---|---|
| Performance | Throughput, latency, memory footprint |
| Compliance | SOC2, HIPAA, GDPR, PCI-DSS compatibility |
| Team fit | Language familiarity, hiring market, learning curve |
| Ecosystem | Library maturity, community, long-term support |
| Scalability | Horizontal/vertical, auto-scaling characteristics |
| Cost | Cloud pricing model, operational overhead |
| Security | Supply chain, CVE exposure, OWASP alignment |
ALGO-41: The Crystallizer¶
Score: 9.6 / 10
Processing time: 100–250ms
Entropy threshold: ≥ 0.8 (Shannon entropy score for golden keywords)
The Crystallizer is the first step in the Tier 9 pipeline — and the most critical. It takes a long-form, noisy, potentially ambiguous input and extracts the minimum set of high-signal keywords needed to unambiguously describe the intent.
Why This Matters¶
Without crystallization, the downstream algorithms work on noisy, ambiguous input — producing lower FDIA scores, larger search spaces for the CSP Solver, and lower-quality Genesis output.
With crystallization, the input to ALGO-40 (ITSR) is a compact, high-entropy intent representation — drastically reducing planning space and improving output quality.
Entropy Scoring¶
Each candidate keyword is scored using Shannon entropy — measuring how much unique information it contributes relative to what's already captured:
A keyword is golden (kept) if: 1. Its Shannon entropy score ≥ 0.8 (high uniqueness) 2. It passes a domain relevance check against the knowledge graph 3. It does not duplicate information already captured by another golden keyword
Code Example¶
from core.tier9.crystallizer import TheCrystallizer
crystallizer = TheCrystallizer(entropy_threshold=0.8)
raw_input = """
I need to build something for my team that can help us detect when
our users are doing things they shouldn't be doing financially —
like maybe spending too much or doing something that looks like fraud.
We process a lot of transactions, probably tens of thousands per second,
and we need it to be fast, like really fast. We're in finance so we
have to be compliant with regulations. Our team mostly writes Python.
"""
crystals = crystallizer.crystallize(raw_input)
print(f"Golden keywords: {crystals.keywords}")
# → ['fraud_detection', 'real_time', 'high_throughput',
# '10k_rps', 'financial_compliance', 'python']
print(f"Entropy scores: {crystals.entropy_scores}")
# → {'fraud_detection': 0.94, 'real_time': 0.91,
# 'high_throughput': 0.88, '10k_rps': 0.87,
# 'financial_compliance': 0.85, 'python': 0.83}
print(f"Input compression: {crystals.compression_ratio:.1%}")
# → Input compression: 94.2% (106 words → 6 golden tokens)
