# Evidence record

## Scope

- App: LocalFlux 1.0.7.0, live Microsoft Store package
- Test date: 2026-08-02
- Host: Windows 11 x64
- Workflow: Compress → Preset → Balanced (recommended)
- Visible source/destination root: `C:\tmp\LocalFlux-batch-compress-20260802`
- Inputs: 12 synthetic files (4 JPG, 4 PNG, 4 WebP)
- Outputs: same folder, `_compressed` suffix

## Aggregate result

- Original bytes: 7,424,843
- Output bytes: 4,123,560
- Bytes saved: 3,301,283
- Reduction: 44.5%
- Completed: 12 of 12
- Smaller outputs: 11
- Already optimized: 1 (`already-optimized-icon.png`)

## Observed app states

1. File picker containing the 12 input-only fixtures under `C:\tmp`.
2. Mixed-format queue ready in Compress mode.
3. Balanced (recommended) selected in Options.
4. Active queue showing completed, converting, and waiting counts.
5. Completion banner: “12 files converted. Preset: Balanced.”
6. Per-file result for the prepared PNG: “8.1 KB → 8.1 KB · Already optimized.”

The screenshots and video show only neutral `C:\tmp` paths. No username or repository location is present in publishable media.

## Original preservation

Each source remained present under its original name. LocalFlux created a sibling output with `_compressed` before the extension. The prepared PNG source and output have the same SHA-256 value, proving that the Already optimized output is byte-identical for that case.

## Format behavior

The mixed batch preserved formats in Compress mode: JPG→JPG, PNG→PNG, WebP→WebP. The one-output-format-per-batch constraint applies to Convert mode, where one target format is selected for the compatible queue.

## Reproduction notes

Use the exact files in `samples/`. Add all 12 to LocalFlux 1.0.7, choose Compress, leave Output as Same as source, select Balanced, and run the batch. Compare results against `test-results.csv` and `outputs/`. Encoder or app changes after the tested version may produce different byte counts.
