GAME BRIEFING
How this lens changes the investigation
Evidence does not become trustworthy merely because it looks technical. Preserve origin, timestamps, handlers, hashes, transformations, and access history. A custody gap reduces confidence but does not automatically prove fabrication.
Observable clues
- Original versus derivative copies, export formats, compression, transcription, translation, and redaction.
- Missing signatures, hashes, seals, handoff times, or handler identities.
- Access after collection and before analysis.
- Whether transformations are reproducible and documented.
Evidence tests
- Identify the earliest available source and preserve it read-only.
- Record every known transfer and transformation.
- Compare cryptographic hashes where appropriate.
- Label gaps and alternative explanations instead of inventing continuity.
Do not assume
- Assuming a screenshot is the original record.
- Treating a hash as proof of truthful content rather than unchanged bytes.
- Calling every gap tampering.
- Ignoring analyst-created notes as transformations.
Gameplay outcomes
- Determines which evidence can support irreversible consequences.
- Creates gameplay around preservation, custody disputes, and independent reconstruction.
- Allows a damaged chain to retain limited evidentiary value with clear warnings.
FICTIONAL PRACTICE // NO ANSWER STORED
Work the lens before revealing the reasoning
Priya Nadar holds a duplicate ledger whose content conflicts with the legal export, but the duplicate passed through two undocumented devices.
A nightly hash receipt identifies the archive state.
The duplicate contains two omitted signed records.
Two device transfers lack documented handlers.
One omitted signer retained a matching paper reference number.
State what the custody gap does and does not establish.
Reveal the worked result and explanation
Defensible result
The gap lowers confidence in the duplicate as a complete original, but the matching hash receipt and independent reference support further authentication. The gap does not itself prove forgery.
Why
- Custody affects weight, not binary existence.
- Independent artifacts can narrow substitution risk.
- The legal export also requires custody review rather than receiving automatic preference.
Common reasoning failure
Choosing whichever copy supports the preferred story and ignoring both custody chains.
