Slate Transforms API Ledger

Current Read

transforms-family deleted-test closure is already banked
current package-local slate transform behavior is green on:
- packages/slate/test/**
- bunx turbo build --filter=./packages/slate
- bunx turbo typecheck --filter=./packages/slate
- bun run lint:fix
- bun run lint
tranche-3 transform/fragment/range-ref owners are now landed:
- transforms-contract.ts
- clipboard-contract.ts
- range-ref-contract.ts
the #6038 benchmark lane now exists and runs:
- bun run bench:slate:6038:local
the old broad-helper explicit-skip read is stale for packages/slate, but is no longer an active owner problem for this package
Transforms.applyBatch(...) is now recovered again as the public batch entry point, backed by the real draft transaction owner Editor.withTransaction(...)
the package is reopened for one explicit transform-family cut:
- legacy ordinary-op adjacent-text/spacer canonicalization rows are no longer kept by default
- owner: /Users/zbeyens/git/slate-v2/packages/slate/test/fixture-claim-overrides.ts
- live rule: heavier adjacent-text/spacer cleanup stays explicit, not automatic on every ordinary structural op

That means the active transforms problem for packages/slate is no longer "missing owner files". It is explicit claim width.

legacy transform width wins by default unless a narrower cut is explicitly justified as no longer relevant to keep
recover only the transform rows that still belong in the kept live claim
for packages/slate, the named owner files now exist and the benchmark owner exists
do not let draft helper modules or green shaped harness rows silently widen or silently narrow the transform claim

Recovered transform grouping is good when it rides the same engine seam. Do not fork batch behavior behind a second implementation path.
