Preserve the source, preserve the reasoning, and leave the system more understandable for the people who use and inherit it.
Stewardship keeps the Journey trustworthy over time. It connects preservation, traceability, documentation, correction, and responsibility so later understanding remains connected to the evidence and decisions that shaped it.
Keep original evidence and source artifacts intact before interpretation or redesign.
Record what changed, why it changed, benefits, trade-offs, and expected long-term effect.
Improve the record without erasing the path that produced the earlier understanding.
Build systems so the next person can understand what exists and why it exists.
