Goal

Sync the stale live plate-2 docs for packages/slate after the final slate-v2 package closeout reached:

• bun test ./packages/slate/test
• bunx turbo build --filter=./packages/slate
• bunx turbo typecheck --filter=./packages/slate
• bun run lint:fix
• bun run lint

all green.

Scope

• update live docs/slate-v2/** control docs that still say tranche 3 / slate transform recovery is pending
• refresh stale docs/solutions/** language that still describes splitNodes(...) as narrow-only
• do not touch support-package / DOM / React tranche docs beyond what the slate completion forces

Findings

Live stale reads

• master-roadmap.md still marks tranche 3 pending
• replacement-gates-scoreboard.md still marks core claim-width audit pending
• release-readiness-decision.md still says merged package corpora do not exist yet and targeted package recovery has barely started
• slate-transforms-api.md still says broad helper breadth remains explicit skip by default
• 2026-04-09-slate-v2-transforms-family-deleted-test-closure.md still marks mergeNodes/*, splitNodes/*, insertNodes/*, insertText/*, removeNodes/* as explicit skip even though the full package suite is green
• 2026-04-07-slate-v2-split-node-should-keep-left-branch-id-and-rebase-inward.md still documents splitNodes(...) as a narrow helper only

Remaining slate package read before edits

• package-local code/test/build/typecheck/lint items: none
• remaining migration program items move to tranche 4+:
  • slate-history
  • slate-hyperscript
  • slate-dom
  • slate-react
  • examples / benchmark / root proof closure
  • final RC ledger closure
