Source-Family Closure Matrix

Cluster	Deleted count	Status	Current proof owner / replacement	Resolution
public hook split surface (`use-composing`, `use-editor`, `use-element`, `use-focused`, `use-read-only`, `use-selected`)	6	`mirrored now`	true-slate-rc-proof-ledger.md, current hooks in `packages/slate-react/src/hooks/*.tsx`	the deleted split hook files are carried by the current `.tsx` hook surface plus existing runtime/surface proof
renderer primitive split surface (`element`, `leaf`, `text`, `string`)	4	`mirrored now`	true-slate-rc-proof-ledger.md, current primitives in `slate-element.tsx`, `slate-leaf.tsx`, `slate-text.tsx`, `text-string.tsx`, `zero-width-string.tsx`	the old primitive split is recovered on the current renderer primitives and structured text surface
chunking/runtime-breadth internals (`src/chunking/**`, `components/chunk-tree.tsx`, `hooks/use-children.tsx`)	8	`explicit skip`	chunking-review.md, architecture-contract.md	child-count chunking is not foundational in v2; semantic islands and selector-local invalidation are the real story
restore-dom rollback internals (`components/restore-dom/**`, `hooks/use-track-user-input.ts`, `hooks/use-is-mounted.tsx`, `hooks/use-mutation-observer.ts`)	5	`explicit skip`	editable.tsx, runtime.tsx	old DOM rollback architecture is replaced by the mounted bridge plus current `Editable` selection/input ownership
old decorate subscription internals (`hooks/use-decorations.ts`, `hooks/use-generic-selector.tsx`)	2	`explicit skip`	surface-contract.tsx, true-slate-rc-proof-ledger.md	exact old decorate machinery is outside the live contract; current value survives through projection-local rendering and recovered public surfaces
Android-only helper internals (`hooks/android-input-manager/**`)	2	`explicit skip`	proof-lane-matrix.md, current composition path in editable.tsx	Android helper internals are not part of the live public/package claim; current IME truth is owned by specialist browser lanes
`src/custom-types.ts`	1	`explicit skip`	interfaces-family-deleted-test-closure.md	declaration-merging `CustomTypes` is outside the live structural typing contract
`src/@types/direction.d.ts`	1	`explicit skip`	none	deleted type residue, not current contributor-facing proof
`src/utils/environment.ts`	1	`explicit skip`	none	deleted React-major helper is not part of the current public or proof surface

What this batch does NOT close

packages/slate-history/test/**
supporting example/browser deletion families
future large-document runtime work like semantic islands or deeper slate-react optimization under runtime quarantine

Why the hard parts were better-cuts

Chunking

current docs already say chunking is not foundational in v2
current source no longer ships the old child-count chunking tree
restoring it would resurrect a runtime-breadth crutch instead of closing the live contract

Restore DOM

the old class-based DOM rollback manager is not the current seam anymore
current Editable owns mounted root selection/input behavior directly
restoring the old rollback layer would create competing DOM truth paths

Android input manager

current IME truth is specialist browser proof, not package-internal Android helper state
if the live contract needed those helpers, the package/browser proof would have exposed it by now

Fresh verification required for this closure
