TOPIC DEPTH / SELF-OBSERVATION
From knowledge to self-observation
This layer organizes the existing topic rules. It does not add new claims or diagnoses.
How to observe
The minimum needed for meaningful self-observation.
Topic boundaries
- do not promise a guaranteed outcome
- do not present self-observation as diagnosis
- do not replace professional help
Data limitations
- Conclusions from a small number of entries are hypotheses.
- Self-report may be incomplete or variable.
- The app observes patterns; it does not confirm causes.
Interpretation limitations
- Do not use this for diagnosis or treatment.
- Do not promise an outcome or health improvement.
- Do not strengthen wording beyond current source verification.
Source limitations
- Sources require manual verification before strong claims are allowed.
Use for education and self-observation. Keep conclusions cautious.
Suggest a small safe step and encourage observation rather than a radical change.
