Summary
Measured shape
The current Next.js/Turbopack workbench emits 19 selected workflow bundles plus one shared registry. The registry module is 2.2 KB encoded (1,652 bytes decoded). This saves roughly 40 KB of aggregate generated artifacts for that fixture; the larger remaining duplication is hybrid/general shared runtime code and is intentionally outside this PR.
This optimization is conservative by design. If the builder cannot prove a serializer is dependency-isolated and order-safe, it keeps the previous self-contained bundle behavior.
Verification
The workbench build still reports its two existing warnings for dynamic world resolution and the Next config NFT trace.
