Default codebook-snapshot rewrite cadence

How many entries between codebook_live.json rewrites. Set to 1 for "after every entry"; default to 1 because the snapshot is small enough that atomic rewrite is cheap (10ms even for a 500-code codebook). A future performance pass may revisit this.

Usage

.LIVE_CODEBOOK_SNAPSHOT_EVERY

Format

An object of class integer of length 1.
