cjs: class method referencing a later module-level function loses the hoisted binding (ajv init: addNames is not defined) — blocks #6559 e2e

[proggeramlug]

Found while landing #6559 (PR #6584): ajv@8 compiles natively (compilePackages) but ajv.compile() throws ReferenceError: addNames is not defined at library init — before any runtime-generated code runs.

Root shape: in ajv's dist/compile/codegen/index.js, class methods call the module-level function addNames that is declared later in the same CJS file. Node hoists the function declaration module-wide; perry's CJS compilation apparently binds the class-method reference before/without the hoisted binding, so the call site sees an undefined free variable.

Repro: run the #[ignore]d e2e in crates/perry/tests/issue_6559_real_libs_e2e.rs (PERRY_REQUIRE_NPM_E2E=1 … -- --ignored), or reduce to: a CJS module where a class method references a function declared after the class, instantiated + called from another module.

Blocks: #6559 real-library acceptance (ajv leg), kimi-code target #6565 (fastify stack inits ajv). The interpreter side is already proven against ajv's captured generated code (PR #6584 fixture suite), so this hoisting gap is the only thing between ajv and green.

Verified on current main (c0d98624a) with the issue’s real ignored e2e: PERRY_REQUIRE_NPM_E2E=1 cargo test --profile perry-dev -p perry --test issue_6559_real_libs_e2e real_ajv_compiled_validator -- --ignored --exact --nocapture. Ajv no longer throws addNames is not defined; it gets past that initialization point and now reaches ReferenceError: module is not defined, the distinct remaining CJS/source-selection wall tracked by #6586. Closing this stale blocker as fixed by later hoisting/capture work.

[proggeramlug]

Reopening after removing the #6586 masking wall. On main, the real e2e stopped first at module is not defined, so the old addNames failure appeared gone. With the hybrid-source routing fixed locally, the graph is uniformly published dist/*.js and Ajv now reaches the original failure again: ReferenceError: addNames is not defined from dist/compile/codegen/index.js. The earlier closure was premature; this still needs its own hoisting fix.
