Digital exhibit provenance: from source file to courtroom display

What makes a digital courtroom exhibit presentation traceable?

A traceable presentation identifies the source item, records every meaningful transformation, distinguishes content from annotation, and preserves the exact version displayed. File integrity, evidentiary authentication, and permission to present are separate questions. A hash or audit log helps investigate a file; it does not establish admissibility by itself.

Classify the thing being shown

Federal Evidence Rule 107 addresses illustrative aids; Rule 1006 addresses certain summaries admitted as evidence; Rule 901 concerns authentication. A slide's category cannot be established by its appearance or by calling it an 'exhibit.' [S1]

• Source item: the document, image, recording, or data received.
• Working copy: a version prepared for review or redaction.
• Presentation derivative: a crop, enlargement, highlight, timeline, or chart.
• Court status: proposed, admitted, limited-use, illustrative, excluded, or unresolved, as actually determined.

A proposed exhibit manifest

Create one manifest row per displayed item, with links back to the underlying source and any transformation instructions. Use stable identifiers rather than relying on filenames such as 'final-final.' Retain restricted material only in its authorized storage location; the manifest can contain a controlled reference rather than duplicating the content.

• Source ID, original filename, custodian or acquisition source, and receipt date.
• Source and derivative checksums, format, page/frame/time range, and tool/version.
• Transformation description: crop boundaries, redactions, scaling, labels, or calculations.
• Reviewer, approval date, court-use status, and displayed version ID.

Synthetic example: an enlarged invoice

A fictional source INV-07 contains three invoice lines. Slide PX-12 enlarges the second line and adds a yellow highlight. The manifest records INV-07, page 1, the crop coordinates, and the added highlight. A caption says 'Enlargement; highlighting added.' The complete source remains available for context. No amount or date is regenerated by an image model.

• Integrity check: the source checksum matches the retained original.
• Content check: every character in the enlarged amount matches the source.
• Context check: the crop does not conceal a qualifying note relevant to the point.
• Status check: the team confirms the permitted use before displaying the slide.

Keep the displayed history when a mistake is found

If a slide misstates an amount, retire the derivative rather than editing its history silently. Link the correction, identify any prior presentation, and let counsel decide what disclosure or corrective step the proceeding requires. This is a proposed control; the actual court's directions govern.

• Freeze the version used at the hearing.
• Record the error, corrected source relationship, and review decision.
• Distinguish correction of a display from alteration of underlying evidence.
• Test the presentation offline and preserve a legible fallback.

Scope and limitations

Proposed technical documentation method with references to U.S. federal evidence rules. This page is not a courtroom, evidence repository, or authentication service.

The manifest is a proposed documentation aid, not a legal foundation or admissibility opinion. No real evidence was collected or transformed.
