# Dnd Kit Foundation

> Use when porting drag-and-drop: signal-reactive drag kernel, activation constraints, collision detection, optimistic sortable reordering, auto-scroll, a11y announcements, or cross-frame feedback rendering from dnd-kit.

# dnd-kit: headless drag-and-drop kernel

## Foundation contract

This is a cold, source-specific foundation, not an operational procedure. It is
historical, revision-pinned evidence rather than timeless guidance. Current
project source, tests, requirements, and runtime behavior outrank this
projection and decide what ships.

## Provenance and revision

- Source record: `dnd-kit`; portable upstream identity, license, coverage caveats, and retrieval history are preserved in the index.
- Recorded revision: `main@6fb57833026e06bb3925eef78316ba56d59749c8`.
- Full provenance, coverage caveats, boundaries, and preserved evidence:
  `references/index.md`.

## Topic map

- Representative topics: Kernel composition; Drag FSM; Action contracts;
  Entity identity & registration; Reactive toolkit; Sensor input; Collision
  plane; Geometry.
- Scope and retrieval questions: `references/index.md#use-this-for`.
- Complete capsule chooser: `references/index.md#load-the-matching-source-dump`.
- Detailed grouped map: `references/index.md#capsule-map`.
- Source limitations and portability boundaries: `references/index.md#boundaries`.

## Retrieval

Open the index, choose one capsule matching the active question, and load only
that capsule. Revalidate its cited source and revision before relying on it. Do
not bulk-load the inventory, treat historical claims as current truth, or apply
this foundation as a procedure.
