# Lossprint

Read a pattern in how several lossy renderings of one source differ in what they lose

Layer: Mind · Category: Reasoning

## Mechanism

The same source is rendered into several targets, such as languages, formats, modalities or audiences, each of which drops something; a single [RepresentationSwap](https://mindscape.world/scapes/bootstrap/RepresentationSwap.md) becomes one of several. For each rendering, what it lost is listed against the source. The loss lists are then compared. A loss every rendering shares suggests something all the examined targets resist. A loss only one rendering shows suggests a blind spot of that rendering or its target. Losses that occur together suggest a structure in the source that those renderings drop as a unit. These are hypotheses about the renderings examined, not established limits of their targets. The finding is stated in terms of these differences, not in terms of what the renderings preserve.

## Invariants

- Uses at least two renderings of the same source into different targets.
- Each rendering's losses are listed against the source, not against another rendering.
- The reported pattern is stated as a relation between loss lists.

## Failure modes

- Invisible loss: something no rendering carried and nobody listed drops out of every comparison.
- Careless rendering: losses caused by a poor rendering are read as structure in the source.
- Shared-loss tunnel vision: only what every rendering lost is examined, so target-specific blind spots are missed.
