- The bundler-CJS rewrite erases recognized __toESM(require("x")) wrappers — module-scope bindings, the `, 1` node-mode variant, inline member reads — down to the bare require at its original offsets; .default accesses pad to the binding where Node's answer is the module (plain-CJS targets, node mode) and stay member reads for __esModule-stamped targets, decided by a require-resolution probe over the target's shipped source (forwarding chains followed)
- Interop the recognizer cannot finish — deviant helper text, escaping interop objects, non-literal arguments, ESM-output calls — answers { degrade }: the fs shadow reports the package as an offender with a note naming the construct and the fallback loop islands it, never a failed build and never the silent alternative (a live helper chain's `var __create = Object.create;` fences at module load while the report claims static); auto and explicit opt-ins share the path
- Bare requires of opted-in packages now behave like relative ones end to end: requireInitStmt emits the dep's inline %init (previously the module never initialized before its exports were read), and cjsLocalModuleBindingOf/resolveValueSymbol resolve member reads and namespace method calls through the npm-static dep's export table
- Erased wrappers join the neutralize set so the helper sweep drops the whole dead chain, hoisted canonical-table texts copied off the source drop .default on module-valued bindings exactly like the pads do, and a file with interop pads but no canonical table still rewrites pads-only
- Fixtures gtcore/gtwrap/gtdrift with cases 2556-toesm-external (byte-matches Node across both dep shapes and the comma-call spelling) and 2557-toesm-drift (construct-naming degrade under explicit and auto opt-ins), excluded from the flagless island lane like the 246x family
