Geometric Calibration Engine (GCE) — Deep Field Orchestrator

Lead Architect & Systems EngineerEngineering Dossier

Achievement Log

2026-04-29: Commenced the architectural overhaul of the Said-Foundation calibration engine. Engineered the 'Deep Field' multi-pass system, replacing legacy biased scoring with geometric identity inference based on 6 semantic axes and 12-field maturity. Implemented Model B (Semantic Embedding) and Model C (Structural Fingerprinting) with magnitude-weighted cosine similarity. Result: A deterministic, transparent, and registry-invariant calibration system that accurately reflects engineering seniority through evidence-based audit.

Overview

Architected and implemented a high-fidelity career calibration engine (v11.0) that transforms multi-modal evidence into a deterministic 12-axis capability radar. Built to replace arbitrary scoring with geometric identity inference.

Implementation & Architecture

Semantic Embedding Model (Model B)

Engineered the linear transformation layer mapping 11 whitened features into a 6-axis capability vector.

Execution Protocol

Implemented feature extraction with logarithmic compression.
Built the whitening matrix logic for signal decorrelation.
Mapped features to semantic axes: Depth, Breadth, Integration, Execution, Abstraction, Stability.

Structural Fingerprinting (Model C)

Designed the identity inference engine using template-based shape matching.

Execution Protocol

Implemented magnitude-weighted cosine similarity for rank determination.
Developed shape-penalty and completeness-penalty algorithms.
Created a magnitude reference (m_ref) anchored to high-level engineering norms.

Deep Field pass (12-Field Multi-Pass)

Recursive engine for field-specific maturity calculations.

Execution Protocol

Engineered the evidence isolation pipeline with significant contribution filtering.
Built field-specific sensor and embedding passes.

Deterministic Evidence Filter (v9.2)

Hardened the ingestion pipeline with intensity and repetition thresholds.

Execution Protocol

Implemented 'Mastery vs Exposure' filtering (Domain/Field validation).
Built ID collision detection and automated YAML formatting.
Established registry-invariant axis normalization constants.
