automatic secret extraction and buffer tracking. +- **Automated Lifecycle**: `api.Call` now automatically "Opens" all `SafeBuf` configuration values before calling Signers, and explicitly closes them via defer. +- **Paradigm Signers**: refactored built-in signers to use naive, declarative syntax (`safe.Base64(safe.Concat(...))`) which leverages `SafeBuf` for encrypted intermediate states, preventing GC reliance. +- **Ultimate Protection**: implemented post-hoc string erasure using `unsafe.String` over controlled buffers managed by a private `wipeableBuffers` list. +- **Infrastructure Alignment**: aligned dependencies with `go/safe` v1.0.6, `go/http` v1.0.11, and `go/config` v1.0.7. + ## v1.0.2 (2026-05-09) ### Changed diff --git a/README.md b/README.md index 3e8e322..e4bfc03
