Summary

vera/wasm.py is currently 2,317 lines — already past the complexity threshold. The WasmContext class carries a lot of state across operators, primitives, arithmetic, memory, and string handling.

Suggested decomposition

Split into a vera/wasm/ package:

• context.py — WasmContext class, core state management
• slots.py — WasmSlotEnv, De Bruijn slot resolution
• strings.py — StringPool, string encoding/decoding
• operators.py — arithmetic, comparison, boolean operators
• memory.py — linear memory, array access, ADT layout
• __init__.py — re-export public API

When

After C7 series completes. C7e (multi-module codegen) will touch wasm.py significantly, so decomposing before that work is done would be premature.
