Slate v2 Op-family First Slice

Supporting plan. For current queue and roadmap truth, see master-roadmap.md.

Goal

• Make the first missing core op-family slice real in /Users/zbeyens/git/slate-v2/packages/slate.

Scope

• Start with the smallest honest op-family/API mismatch already implied by docs.
• Prefer insert_node / remove_node plus matching Transforms wrappers if the core can support them cleanly.

Phases

• Confirm the exact mismatch and current code seams
• Write focused failing tests
• Implement the smallest honest core/API slice
• Sync package/public docs
• Verify the touched package/docs

Finding

• The current slate docs already implied insert_node / remove_node and Transforms.insertNodes(...) / Transforms.removeNodes(...), but the package only implemented four operations and four transform helpers.

Slice

• Add real insert_node / remove_node operation types and core apply cases.
• Add path-based Transforms.insertNodes(...) / Transforms.removeNodes(...).
• Keep the slice narrow:
  • no fake broad NodeOptions parity
  • no selection-heavy transform semantics
  • no broader node families yet

Verification

• yarn mocha --require ./config/babel/register.cjs ./packages/slate/test/snapshot-contract.ts
• yarn test:mocha
• yarn workspace slate-react run test
• targeted tsc diagnostics on changed packages/slate files: 0 errors
• yarn exec eslint on changed packages/slate files
• yarn prettier --check on changed slate-v2 files
• pnpm exec prettier --check on changed plate-2 docs

Notes

• repo-wide yarn lint:typescript still hits stale workspace *-v2 tsconfig references outside this slice
• repo-wide yarn lint:eslint still reports thousands of unrelated existing issues, so targeted eslint was the honest signal for the changed files

Follow-on

• the next honest slate op-family slice is path-based set_node / Transforms.setNodes(...)
