Log Packages

Ophiolite log packages are optimized local storage units for one log asset.

Layout

log_asset.laspkg/
  metadata.json
  curves.parquet

Why Parquet

Curve data is stored column-wise to support:

• projected reads
• depth-window access
• efficient package persistence

Ophiolite does not patch Parquet in place. Saves rewrite the payload into a new immutable revision snapshot and rematerialize the visible package head from that revision.
