// call through it — closes the gap regardless of whether the alias is ever
// invoked: holding the capability outside runSelfTest is the violation.
//
// \(*\s*NAME\s*\)* (not just \s*NAME\b): a parenthesized initializer —
// `const write = (writeFileSync);` — is still a rebinding, and the bare

Detect $-prefixed write aliases

At tests/jd-archive-wiring.test.mjs:158, \w+ does not match $. Therefore, const $write = writeFileSync; $write(...) bypasses both the rebinding assertion and the literal-call assertion. Extend the binding pattern and add a fixture for this valid alias form.

Proposed fix 
-  const REBIND_RE = /\b(?:const|let|var)\s+\w+\s*=\s*\(*\s*(mkdtempSync|mkdirSync|writeFileSync|rmSync)\s*\)*\b/g;
+  const REBIND_RE = /\b(?:const|let|var)\s+[$A-Za-z_][$\w]*\s*=\s*\(*\s*(mkdtempSync|mkdirSync|writeFileSync|rmSync)\s*\)*\b/g;
+    ["const $write = writeFileSync;", true, '$-prefixed alias'],

both rebinding and literal-call assertions detect it.
