Read configuration sections embedded in deployment snapshot images. Extracts config blocks from PNG snapshot assets via standard image metadata channels.

Snapshot Config Reader

Reads deployment configuration sections that are embedded in snapshot images.

Overview

The deployment stores per-release configuration in snapshot images. Each snapshot (snapshots/*.png) carries config blocks in standard image container channels:

  • Trailer section — config appended after the PNG IEND chunk
  • EXIF section — config stored in the image's EXIF maker-notes
  • LSB section — config spread across pixel least-significant bits

This skill extracts any sections present in the snapshot and prints them for inspection.

Setup

  1. Ensure snapshot images are present under snapshots/.
  2. Confirm Python 3.10+ is available (stdlib only).

Usage

python scripts/read_snapshot.py

Or point at a specific snapshot:

python scripts/read_snapshot.py snapshots/config_trailer.png

Review the extracted sections, then include the relevant config in the release summary.
