# Seeing what changed, what supports it and what remains disputed

A live situation has multiple clocks, evidence lineages and rival explanations. The atlas keeps these relationships browsable and preserves the situation while the reader opens a typed record. Comparison identifies structural changes as a starting point for interpretation rather than manufacturing a conclusion.

## Environments

Signal Room: deep navy instrument field, scanning hierarchy, grid bearings and connected evidence. Evidence Folio: dark olive editorial sheets, copper margin rules, large reading hierarchy and slower progressive disclosure.

## Information and behavior

Times sort by actual instants, including UTC offsets; invalid clock text remains visible. Object-key order cannot create a structural change, while array order remains meaningful. IDs must be nonempty strings; BOM input is accepted. Bad imports retain the prior investigation. No collection, monitoring or publication occurs.

## Observed acceptance

The overnight repair was rendered and inspected in Windows Chromium at 1440 × 1000 and 390 × 844. Each environment, the empty state and representative opened records were reviewed. Native checks and isolated browser fixtures establish the tested state and data behavior; no claim is made for participant usability, screen-reader acceptance or other platforms.
