google-labs-jules[bot]	9da28a6416	feat(spire-ffi): implement native Argon2id derivation - Added `argon2` v0.5 dependency to `spire_ffi/Cargo.toml` - Implemented `argon2id_derive` FFI function in `spire_ffi/src/lib.rs` with C-ABI. - Added Deno FFI binding `deriveArgon2idKey` in `server/spire_ffi.ts` with `nonblocking: true` to prevent stalling the event loop. - Pre-allocates output buffer on the Deno side as the standard FFI pattern. - Included fallback mock behavior when `libspire_ffi.so` is not loaded, returning a 32-byte 0xaa filled array. - Updated unit tests in `server/spire_ffi.test.ts` to test mock usage and successful generation.

google-labs-jules[bot]	3d66535889	feat: implement zero-dependency real-time event bus in AuthSdk Added a lightweight, zero-dependency event bus to the `AuthSdk` to listen for Valkey RESP3 push invalidation events and emit them to registered listeners. The implementation properly captures errors from synchronous and asynchronous listeners, ensuring they do not crash the primary SDK listener loop. Extracted the Valkey event processor to improve hermetic testability. Co-authored-by: mrteye <1945243+mrteye@users.noreply.github.com>	2026-08-24 04:19:40 +00:00
