Write the reasoning
Every decision starts with a written case. The record separates observed facts from judgment.
Operating principles
Every decision leaves
a usable record.
True North Quant combines systematic coverage with explicit judgment. The software preserves both.
The principles
Discipline must appear in the process.
Each principle maps to a visible control in the research and portfolio system.
Test the opposing view
An independent reviewer attacks the thesis, the evidence, and the proposed kill condition.
Keep the complete set
The process retains approved, rejected, missed, and invalidated cases. It does not hide an inconvenient result.
Use deterministic controls
Software applies portfolio and execution rules from stored state. It does not invent quantities or bypass a failed check.
Change one thing at a time
Research improvements become falsifiable hypotheses. Tests compare a clear change with a fixed baseline.
State the limits
Model results remain model results. Missing evidence stays missing, and uncertainty remains visible.

Current boundary
The public record describes model portfolios.
The method makes no live performance claim. It keeps model evidence distinct from verified live results.
