@kbn/core-chrome-navigation-customization

Pure, stateless algorithms for the customizable side navigation feature. These functions encode/decode the delta-from-default storage format used to persist a user's navigation reordering as a minimal list of moves.

This package has no React, EUI, or platform dependencies (only @kbn/core-chrome-browser types), so it can be dynamically imported by the navigation plugin and statically imported by @kbn/core-chrome-browser-internal without bloating the page-load bundle.

Exports

• computeMoves(defaultOrder, userOrder) — produces the minimal set of intent-preserving moves (via an LCS/LIS diff) that transforms defaultOrder into userOrder. Used when saving a customization.
• replayMoves(items, moves, getId) — replays a saved list of moves on top of the current default order, skipping moves whose id or afterId no longer exist (version-skew resilience). Used when applying a stored customization.
