// Regression: map keys kept their bytes across a cross-package return on wasm.
//
// The map fixup paths wrote a string/[]byte header's length at the hardcoded
// offset 8 (and cap at 16) - correct only where a pointer is 8 bytes. On wasm
// the length landed in the cap slot and the length field stayed 0, so every
// map key decoded empty: the relay proxy re-serialized a tag filter
// {"#p":[pubkey]} as {"":[pubkey]} and matched nothing.
//
// Fixed in: src/runtime/codec.mx (codecDecodeMapValue, fixKey/fixStrVal/fixIface
// use codecPtrSize() offsets) and src/runtime/relocate.mx
// (relocFixupInterfaceValue).
