Goal

Move /Users/zbeyens/git/slate-v2/packages/slate/test/interfaces/Editor/edges off the Mocha fixture harness onto the root Bun test graph as the next bounded slice.

Constraints

• keep the single root bunfig.toml
• do not broaden the slice past Editor/edges
• keep the Editor/above Bun slice green
• do not leave the Mocha lane double-owning the same fixtures

Findings

• Editor/edges uses the same legacy TSX fixture shape as Editor/above
• the fixtures still import a shared hyperscript symbol through packages/slate/test/index.js
• a direct Bun spec red-pass fails because that import re-enters the Mocha harness and the imported fixture editor is still miscompiled without the scoped preload bridge
• Editor/above and Editor/edges can share the same Bun fixture-spec runner
• the shared runner now lives at /Users/zbeyens/git/slate-v2/packages/slate/test/bun/support/run-editor-fixtures.js
• the scoped Bun preload bridge now covers both Editor/above/*.tsx and Editor/edges/*.tsx through one shared test-directory rule
• the migrated Bun fixtures can use stock slate-hyperscript tags like <element> and avoid any extra local helper file
• the migrated edges fixtures are also bare TSX with the stock factory import injected by the preload

Plan

1. Extract a reusable Bun editor-fixture runner for slate interface slices
2. Move Editor/edges onto a Bun spec using that runner
3. Exclude Editor/edges from the legacy Mocha fixture recursion
4. Extend the scoped Bun preload bridge to cover Editor/edges/*.tsx
5. Verify build, typecheck, lint, Bun, and Mocha

Verification

• bun test ./packages/slate/test/bun/editor-edges.spec.tsx
• pnpm turbo build --filter=./packages/slate
• pnpm turbo typecheck --filter=./packages/slate
• pnpm lint:fix
• pnpm test:bun
• pnpm test:mocha
