## 07 Methods and limitations

- Source times are never overwritten. Each event keeps the timestamp exactly as recorded next to its normalized time and the rule that produced it.
- Log files (CSV) are parsed deterministically; extraction for video, audio and PDF is simulated in this demo and is labelled as such.
- In this demo the E-02 clock offset is declared in the fixture metadata, not inferred from the evidence.
- Conflicts come from deterministic rules with stable IDs. A conflict is a prompt for human review, not proof of tampering.
- Every claim keeps its state (supported, contradicted, inferred or unresolved); the report does not drop uncertainty to make the timeline look cleaner.
- Hypotheses carry no probability score. The system compares evidence; it does not pick a winner.
- Results on a small synthetic case say nothing about accuracy on real investigations.
