Test-Family Closure Matrix

Deleted file / cluster	Deleted count	Status	Current proof owner / replacement	Resolution
harness files (`test/index.js`, `test/jsx.d.ts`)	2	`explicit skip`	history-contract.ts	deleted fixture harness files add no current contributor-facing value; the live proof surface is the direct contract suite
`test/isHistory/*`	4	`recovered now`	history-contract.ts	direct proof now keeps `History.isHistory(...)` true before edits and across edit, undo, and redo lifecycle
`test/undo/cursor/keep_after_focus_and_remove_text_undo.js`	1	`recovered now`	history-contract.ts	direct proof now restores the saved expanded selection after delete, blur, refocus, and undo
`test/undo/delete_backward/block-join-reverse.tsx`, `block-nested-reverse.tsx`, `block-text.tsx`	3	`recovered now`	history-contract.ts	direct proof now restores reverse block joins, reverse nested block joins, and reverse same-text deletes
`test/undo/delete_backward/custom-prop.tsx`	1	`explicit skip`	history-contract.ts	the old cross-block delete shape is wider than the live delete helper contract; current same-text custom-prop restore is proved directly instead
`test/undo/delete_backward/inline-across.tsx`	1	`explicit skip`	history-contract.ts	the old cross-inline multi-block delete shape is wider than the live delete helper contract; current same-text inline restore is proved directly instead
`test/undo/insert_break/basic.tsx`	1	`recovered now`	history-contract.ts	direct proof now restores `insertBreak()` commits
`test/undo/insert_fragment/basic.tsx`	1	`explicit skip`	history-contract.ts, clipboard-contract.ts	the deleted deep nested fragment shape is beyond the current simple-block fragment contract; current simple block fragment undo is proved directly instead
`test/undo/insert_text/basic.tsx`	1	`recovered now`	history-contract.ts	direct proof now restores a plain `insertText(...)` commit
`test/undo/insert_text/contiguous.tsx`, `test/undo/insert_text/non-contiguous.tsx`	2	`explicit skip`	history-contract.ts, Readme.md	legacy timing-based auto-merge heuristics are not the live contract; the current package uses one outer transaction per undo unit and explicit merge helpers

Totals:

recovered now: 10
explicit skip: 7
reconciled deleted test paths: 17

What Was Recovered

history-contract.ts now directly proves:
- History.isHistory(...) stays true before edits and across undo/redo
- a plain insertText(...) commit is undoable
- reverse block joins and reverse nested block joins undo cleanly
- reverse same-text deletes undo cleanly
- same-text deletes keep custom props and inline node content on undo
- delete-fragment selection restore survives deselect and refocus before undo
- insertBreak() commits undo cleanly
- current simple block fragment insertion undoes cleanly

Explicit Skip Rationale

Harness files

test/index.js and test/jsx.d.ts were fixture plumbing
reviving them would rebuild dead harness shape instead of strengthening the current contract suite

Cross-node delete helper width

the current delete helper contract is narrower than the old cross-block/cross-inline fixture shapes
this batch keeps history proof honest by proving the supported same-text delete surface directly and cutting the wider legacy rows explicitly

Deep nested fragment depth

current fragment proof is the simple block fragment seam
reviving the deleted nested fragment fixture would overclaim a wider fragment contract than the live package currently proves

Legacy auto-merge heuristics

the current package does not promise timing-based contiguous insert merge
the live contract is:
- one outer transaction is one undo unit
- merge boundaries are explicit through withMerging(...), withNewBatch(...), and withoutMerging(...)

Package Parent Tree

Scope	Status	Notes
`packages/slate-history/**`	`open`	parent stays open because deleted `src/history.ts` and package-root residue are outside this batch
`packages/slate-history/test/**`	`closed`	closed by this note
`packages/slate-history/src/history.ts`	`open`	deleted source rewrite still needs explicit file-level audit against the current package surface
`packages/slate-history/CHANGELOG.md`	`open`	package-root changelog residue still needs explicit low-priority disposition

Sibling buckets still open

packages/slate-history/src/history.ts
packages/slate-history/CHANGELOG.md
