Prototyped extending the @fusion/core pre-bundle alias lever to @fusion/engine's relative-import production graph reached by the 18 gate files, but an A/B showed no clear win over the @fusion/core-only bundle, so the change was not landed and only the rationale is recorded.
- Added an FNXC:EngineTests comment block in packages/engine/vitest.config.ts documenting the FN-7670 prototype (171 first-party files → 35 output files via esbuild multi-entry splitting)
- Recorded the negative A/B result: byte-size growth of 14 separate large root bundles offset per-file-dispatch savings, with no clear win beyond host run-to-run noise
- Left the vitest alias wiring unchanged at the @fusion/core-only bundle state, pointing future attempts to FN-7670's task docs for full analysis and to consider a single combined engine-graph entry instead of 14 separate root entries
