What We Built

Three hardened headers. Six rounds of expert code review. Every lifetime, overflow, and validation edge case addressed.

PERCEPTION ENGINE

ClinicalPrior

Core engine scaffold with modality-specific validation:

  • Buffer consistency — point_count × stride ≤ bytes
  • Overflow-safe — size_t voxel multiplication
  • Config validation — Initialize() and Reconfigure()
  • Anomaly gating — only when persistence is enabled
  • 8 regimes — Normal → Critical → Deteriorating
SENSOR ADAPTERS

DICOM Utils

Safe data conversion with ownership-aware lifetime contract:

  • SegmentVoxelGrid — CT HU threshold → 3D point cloud
  • ProcessECGWaveform — R-peak detection, HRV (SDNN)
  • OwnedVitalsBuffer — no thread_local lifetime trap
  • Synthetic generators — CT, ECG, vitals for testing
DECISION LAYER

Clinical Council

3-agent modality-gated consensus system:

  • ImagingAgent — CT, MRI, Ultrasound, Pathology, Retinal
  • VitalsAgent — VitalsStream, ECG, EEG
  • LabsAgent — LabPanel (stub for fusion)
  • Support-weighted — not "highest urgency wins"
  • Decision-support language — never diagnosis
ACUITY SCORING

5-Level Clinical Acuity

Composite scoring from topology metrics:

  • Level1-Immediate — anomaly > 0.85
  • Level2-Emergent — specialist review
  • Level3-Urgent — elevated monitoring
  • Level4-SemiUrgent — routine follow-up
  • Level5-NonUrgent — normal baseline
"The clinical engine does not diagnose — it detects structural anomalies in sensor data and converts them into auditable decision-support signals for human clinicians."

A Different Kind of Clinical Pipeline

Most clinical alerting is threshold-based. Most AI is black-box. This engine sits in between — structural, deterministic, interpretable.

RULE-BASED ALERTING

Threshold → Alert

Sensor→ Threshold Check→ Alert / Silence
Simple and auditable, but structurally blind. Misses multi-variable patterns, trajectory context, and structural anomalies. High false-alarm rate.
DEEP LEARNING

Sensor → Neural → Prediction

Sensor→ CNN / Transformer→ Classification
Can find subtle patterns, but less interpretable. Hard to audit. Harder to govern. FDA pathway requires extensive validation infrastructure.
EHR ANALYTICS

Records → Model → Risk Score

EHR Data→ Feature Eng.→ ML Model→ Score
Good for population health, but batch-oriented. Not real-time. Not sensor-native. Doesn't see topology.
APEX17 CLINICAL

Real-time structural analysis with full audit trail: fingerprint, council votes, reasoning strings, regime classification. Every output is a decision-support signal, not a diagnosis.
DIFFERENTIATORS

Five Architecture-Level Differences

These are not incremental feature additions. They are structural design choices that change what the system can prove.

01

Modality-Agnostic Topology

The same H₀ persistence engine processes CT point clouds, ECG time series, and vitals trajectories. No modality-specific neural networks required.

This means new sensor types require only a data adapter, not a new model architecture. The validated cross-modality similarity is 1.000 (CT↔MRI).
02

Deterministic Fingerprinting

PathologyFingerprint produces a 64-bit hash from topology features. Same input → same hash, always. Similarity uses std::popcount for portable Hamming distance.

Fingerprint similarity = 1.000 for identical inputs across runs. This enables O(1) recall: "have I seen this structural pattern before?"
03

Modality-Gated Council

Agents only vote when relevant to the input modality. CT input activates ImagingAgent; VitalsAgent and LabsAgent abstain. No "phantom votes" from irrelevant specialists.

Consensus confidence measures agreement among relevant agents, not total agent count. This prevents a 3-agent system from appearing to have 3× confidence on a single-modality input.
04

Auditable Decision Chain

Every decision carries: fingerprint hash → council votes → reasoning strings → regime classification → acuity level. All timestamped, all deterministic.

This is important for regulatory audit trails. The system can prove exactly why it produced a specific signal for a specific input.
05

Decision-Support, Not Diagnosis

The engine explicitly frames outputs as signals for clinician review. "Specialist review recommended" — never "patient has condition X." This is a design choice, not a limitation.

Clinical overreach is an architectural violation. The council uses softened language: "elevated structural anomaly" instead of "biopsy recommended."
HONEST ASSESSMENT

What This Proves. What Production Needs.

This scaffold demonstrates the architecture works. Production healthcare requires significantly more.

What This Scaffold Proves

  • Modality-agnostic topology works on clinical data
  • Same math as robotics and markets — one engine
  • Deterministic fingerprinting enables recall at O(1)
  • Support-weighted council prevents urgency escalation bias
  • Buffer safety — overflow-safe, lifetime-correct, validated
  • Audit trail — every output traceable to input

What Production Would Need

  • FDA 510(k) or De Novo — regulatory pathway
  • Clinical validation — real patient data, IRB approval
  • HIPAA compliance — phi handling, encryption, access control
  • HL7/FHIR integration — standard clinical data exchange
  • Real PH kernels — replace heuristic scaffold
  • Clinical partner — hospital system for validation
CROSS-DOMAIN

Same Math. Three Domains.

The topological identity engine is domain-agnostic. H₀ persistent homology works on any structured data — spatial, temporal, or clinical.

Robotics

LiDAR point cloud → persistence stability. Low stability = unstable room → Director Governor veto. O(1) SceneMemory prevents re-solving known environments.

35ms CUDA · 28 Hz

Markets

Price series → persistence stability. Low stability = regime transition → Director confidence cut. O(1) hash recall identifies previously seen market structures.

0.16ms CPU · sub-1ms

Healthcare

CT/ECG/Vitals → persistence topology → clinical council → acuity signal. Modality-gated agents, support-weighted consensus, FDA-auditable output chain.
