 - `importMetaPrelude` (`auto`): emit a no-op `void import.meta.filename;` touch. `on` always emits; `off` never emits; `auto` emits only when helpers that reference `import.meta.*` are synthesized (e.g., `__dirname`/`__filename` in CJS→ESM, require-main shims, createRequire helpers).

+- `detectCircularRequires` (`off`): optionally detect relative static require cycles across `.js`/`.mjs`/`.cjs`/`.ts`/`.mts`/`.cts` (realpath-normalized) and warn/throw.
 - `detectDualPackageHazard` (`warn`): flag when `import` and `require` mix for the same package or root/subpath are combined in ways that can resolve to separate module instances (dual packages). Set to `error` to fail the transform.
 - `dualPackageHazardScope` (`file`): `file` preserves the legacy per-file detector; `project` aggregates package usage across all CLI inputs (useful in monorepos/hoisted installs) and emits one diagnostic per package.
 - `topLevelAwait` (`error`): throw, wrap, or preserve when TLA appears in CommonJS output. `wrap` runs the file body inside an async IIFE (exports may resolve after the initial tick); `preserve` leaves `await` at top level, which Node will reject for CJS.

 ## Idiomatic Exports
 
-Shipped: `idiomaticExports: 'safe'` is now the default for CJS → ESM, with fallback to the helper bag plus diagnostics when unsafe. Auto lifts simple `module.exports = { foo, bar }` object literals to idiomatic exports when safe.

-Next:
-
 - Explore a true `'aggressive'` mode (mixed exports/module.exports, limited reassignments, identifier-safe computed keys) with guarded semantics and explicit diagnostics.
 - Consider a constrained ESM → CJS “pretty” path where live-binding and TLA semantics permit it.
 
 ## CLI
 
-- Shipped parity CLI wrapping the core transform (targets, rewriteSpecifier, appendJsExtension/appendDirectoryIndex, detectCircularRequires, topLevelAwait, cjsDefault, diagnostics hooks, out/in-place) with stdin/stdout support, JSON/summary, and list/dry-run paths.
-- Next: optional concurrency flag, `--watch` mode with minimal restarts, and a tiny stream type surface to keep test stubs and embedding clean.
+- Optional concurrency flag, `--watch` mode with minimal restarts, and a tiny stream type surface to keep test stubs and embedding clean.
 - DX polish: keep help/examples in sync with tests; retain single-fixture CLI coverage unless new CLI-specific behaviors emerge (e.g., multi-ext glob ordering, large-input streaming), since transform semantics are already exercised in module fixtures.

 ## Potential Breaking Changes (flag/document clearly)
 
-- Template literal specifier rewriting: if we ever default to skipping interpolated `TemplateLiteral` specifiers, it would change outputs. Current implementation is opt-in via `rewriteTemplateLiterals: 'static-only'` (non-breaking); future default flips would need a major/minor note.
-- Cycle detection hardening: expanding extensions (.ts/.tsx/.mts/.cts) and normalize/realpath paths may surface new cycle warnings/errors, especially on Windows or mixed TS/JS projects.
+- Template literal specifier rewriting: changing the default to skip interpolated template literals would be breaking.
