#10056) ### What Builds on the parent PR (#10020). A JSON module imported as a namespace (`import * as ns from './x.json'`) keeps every top-level key materialized — the finalizer only inlines JSON keys when the module namespace object is **not** included (`need_inline_json_prop`, see `finalizer_context.rs`). > **This is pre-existing behavior, not a regression.** On `main` a namespace-imported JSON chunk under `preserveModules` already exports its full interface correctly — `import('./dist/data.js')` exposes every top-level key. Unlike #10020 (which *is* a #9934 regression), there is no namespace bug on `main`. I verified the guard test passes on `main`. The reason this PR exists is purely to keep the stack consistent: the parent PR's #10020 narrowing (skip keys absent from `json_module_none_self_reference_included_symbol`) is too coarse for the namespace case — those keys are absent from that set yet still materialized, so the **parent PR alone** would drop them: ```js // parent PR (#10020) alone: only the namespace object survives export { data_exports }; // with this PR: pre-existing full interface preserved export { answer, data_exports, data_default as default, nested }; ``` ### Fix Mirror the finalizer's **full** inlining condition rather than the key-set alone: only drop a key when JSON property inlining is actually active — JSON, ESM exports, and the namespace object **not** included. The stack's net behavior then matches `main` for the namespace case. ### Test `crates/rolldown/tests/rolldown/misc/preserve_modules/json_namespace_preserves_exports`: `import * as` a JSON module under preserveModules and assert (via `_test.mjs`) that `import('./dist/data.js')` re-exposes every top-level key plus `default`. Verified: passes on `main`, fails on the parent PR alone, passes here. --- > Stacked on the #10020 fix.
