docs(slice-2d): findings consolidados — serde/std leak via types/std identified
Slice 2d empirical investigation completada (sesión 2 cont 2026-05-24):
- WASM_BUILD_STD=0 resuelve alloc/exchange_malloc (Slice 2c attempt #5)
- NEW layer: panic_impl duplicate via serde/std leak transitive
- Diagnostic vía cargo tree wasm32 -e features: ruta exacta identificada
`origin-chain-types feature "std"` → `serde feature "std"` activation
- Root cause: dep transitive activa types/std en wasm32 build incluso
con --no-default-features (probable macro expansion automation)
Slice 2e future requires architectural fix:
- [patch.crates-io] serde override con strict no-std
- O sp-io feature gate adjust
- O wait stable2512-4+ upstream
Mientras Slice 2e land: build.rs no-op + Slice 3 v0.0.13 mock-WASM estable.
