@helipod/index-key-codec

Order-preserving index key encoding for range scans over Helipod documents.

This package encodes tuples of indexable values into byte strings whose lexicographic order matches the logical sort order of the values, which is what lets any storage backend answer index range queries with a plain byte-range scan. It is also the canonical home for the key-range machinery built on top of that encoding: key ranges and range sets, keyspace identifiers, cursors, an interval index for fast range intersection, and the serialized write-invalidation shapes the sync tier uses to decide which subscriptions a commit affects.

Every other engine package imports these types from here rather than redeclaring them, keeping the read side, write side, and sync tier in exact agreement about key order.

This is an internal package of the Helipod engine. Most applications should install helipod instead.
