Slate Legacy + Draft Contract Corpus

• owner: packages/slate
• tranche: 3
• rule: legacy and draft rows are evidence, not automatic veto power over the better API

Purpose

Merge the three competing sources of truth for slate package work:

1. legacy exact tests/docs
2. draft contract tests/docs
3. current proof owners

This corpus is execution evidence for tranche-3 redesign.

It is stricter than source-diff nostalgia, but it is no longer allowed to force a worse retrofit API when the redesign direction is clearer and better.

• /Users/zbeyens/git/slate-v2/packages/slate/src/**
• /Users/zbeyens/git/slate-v2/packages/slate/test/**

Row Classes

• both
  • a behavior or API row is supported by both legacy and draft evidence
• legacy-only
  • legacy requires it; draft does not materially strengthen it
• draft-only
  • draft adds intended v2 value not contradicted by kept legacy rows
• dead
  • harness-only, manifest-only, or otherwise outside the kept public claim

Execution dispositions:

• keep-now
• keep-later
• explicit-cut
• post RC

keep-now

Legacy-backed public editor/query rows

• Editor.before(...)
• Editor.after(...)
• Editor.next(...)
• Editor.previous(...)
• Editor.nodes(...)
• Editor.levels(...)
• Editor.positions(...)
• Editor.unhangRange(...)
• Editor.node(...)
• Editor.path(...)
• Editor.point(...)
• Editor.range(...)
• Editor.start(...)
• Editor.end(...)
• Editor.string(...)

Class:

• mostly both
• these rows now also have draft or current proof pressure through query-contract.ts, surface-contract.ts, and current API ledgers

Immediate current proof owners to restore or keep alive:

• .tmp/slate-v2/packages/slate/test/query-contract.ts
• .tmp/slate-v2/packages/slate/test/legacy-editor-nodes-fixtures.ts

Current read:

• restored and green:
  • query-contract.ts
  • legacy-editor-nodes-fixtures.ts

Legacy-backed interface and utility rows

• Path.*
• Point.*
• Range.*
• Node.*
• Element.*
• Text.*
• Operation.*
• Scrubber.*

Class:

• mostly both

Immediate current proof owners to restore or keep alive:

• .tmp/slate-v2/packages/slate/test/interfaces-contract.ts
• .tmp/slate-v2/packages/slate/test/legacy-interfaces-fixtures.ts

Current read:

• restored and green:
  • legacy-interfaces-fixtures.ts
• still pending:
  • interfaces-contract.ts

Legacy-backed transform and operation rows

• kept Transforms.move(...)
• kept Transforms.delete(...)
• kept Transforms.select(...)
• kept Transforms.setPoint(...)
• kept Transforms.setSelection(...)
• kept node transform families already represented in the exact legacy ledger

Class:

• mostly both

Immediate current proof owners to restore or keep alive:

• .tmp/slate-v2/packages/slate/test/transforms-contract.ts
• .tmp/slate-v2/packages/slate/test/operations-contract.ts
• .tmp/slate-v2/packages/slate/test/legacy-transforms-fixtures.ts

Draft-backed public transaction/snapshot/store rows

• Editor.getChildren(...)
• Editor.getOperations(...)
• Editor.setChildren(...)
• Editor.getSnapshot(...)
• Editor.replace(...)
• Editor.reset(...)
• Editor.subscribe(...)
• Editor.withTransaction(...)
• transaction draft visibility through withTransaction(editor, tx => ...)
• Transforms.applyBatch(...)
• snapshot publication and transaction visibility semantics
• bookmark and range-ref public durability seams

Class:

• mostly draft-only, but compatible with kept legacy public behavior

Immediate current proof owners to restore or keep alive:

• .tmp/slate-v2/packages/slate/test/surface-contract.ts
• .tmp/slate-v2/packages/slate/test/transaction-contract.ts
• .tmp/slate-v2/packages/slate/test/snapshot-contract.ts
• .tmp/slate-v2/packages/slate/test/bookmark-contract.ts
• .tmp/slate-v2/packages/slate/test/range-ref-contract.ts

Draft-backed current contract rows that still matter to product truth

• clipboard contract
• normalization contract
• headless contract
• text-units contract

Class:

• draft-only
• keep because they describe intended v2 runtime behavior not covered well by the old exact legacy rows

Immediate current proof owners to restore or keep alive:

• .tmp/slate-v2/packages/slate/test/clipboard-contract.ts
• .tmp/slate-v2/packages/slate/test/normalization-contract.ts
• .tmp/slate-v2/packages/slate/test/headless-contract.ts
• .tmp/slate-v2/packages/slate/test/text-units-contract.ts

keep-later

• legacy CustomTypes rows
  • current live docs said explicit skip
  • the broader redesign doctrine reopens them for explicit re-evaluation
  • do not silently keep or cut them
• broader draft helper-module adoption with no immediate kept-row pressure:
  • draft-helpers
  • transaction-helpers
  • text-units implementation shape beyond kept behaviors
  • other draft-only source helpers whose value is still indirect
• benchmark/perf harness promotion beyond already kept runtime rows

explicit-cut

• legacy harness-only rows with no behavior value:
  • packages/slate/test/index.js
  • packages/slate/test/jsx.d.ts
  • old batch matrix manifests
  • old perf manifest files
• exact legacy partial-commit batch failure semantics already replaced by atomic rollback under the kept transaction contract
• dead deep-equal helper family outside the kept public surface
• legacy ordinary-op adjacent-text/spacer canonicalization rows that conflict with the live explicit-only normalization contract
  • owner: /Users/zbeyens/git/slate-v2/packages/slate/test/fixture-claim-overrides.ts
  • read: these rows expected ordinary transforms like moveNodes, insertNodes, insertFragment, mergeNodes, wrapNodes, and related delete/split helpers to coalesce adjacent text or strip spacer text automatically
  • live claim: that cleanup is explicit-only unless a narrower kept row proves otherwise

post RC

• draft-only architecture helpers that may still be valuable after the replacement claim is honest
• broader benchmark/root proof command adoption
• any future widening driven by product value rather than parity pressure

Immediate Execution Consequence

The next slate code batches must be planned from these proof owners, not from source similarity:

1. query-contract.ts + legacy-editor-nodes-fixtures.ts
2. interfaces-contract.ts + legacy-interfaces-fixtures.ts
3. transforms-contract.ts + operations-contract.ts + legacy-transforms-fixtures.ts
4. surface-contract.ts + transaction-contract.ts + snapshot-contract.ts
5. bookmark-contract.ts + range-ref-contract.ts + clipboard-contract.ts + normalization-contract.ts

If current .tmp/slate-v2/packages/slate/src/** cannot satisfy those rows cleanly, rewrite it.
