spatialpack hash

Usage

# Compute BLAKE3 hashes for all layers and write to manifest
spatialpack hash ./my-pack/

# Verify existing hashes (exits non-zero on mismatch)
spatialpack hash --verify ./my-pack/

What it does:

• Reads layer file paths from spatialpack.json (manifest-driven, not filesystem scan)
• Computes BLAKE3 hashes for each asset (layers/*.parquet, layers/*.pmtiles, rasters/*.tif)
• Writes hashes to integrity.asset_hashes in the manifest (keys: layers/roads.parquet, etc.)
• --verify compares computed vs stored; exits 1 on any mismatch, missing file, or unhashed asset

Description

Compute BLAKE3 integrity hashes for pack assets.

Options

Option	Type	Default	Description
--verify	flag	false	Verify existing hashes; exits 1 on mismatch, missing file, or unhashed asset

Installation

Requires the blake3 package:

pip install blake3
# or install all extras
pip install -e ".[full]"
