+# Rust Stability Fix for Issue #23
+
+## Problem
+The project fails to build with stable Rust (1.81.0) due to extensive use of unstable features in dependencies and the main codebase.
+
+## Root Cause
+The project uses many unstable Rust features that are only available in nightly Rust:
+- `platform-data` dependency uses unstable features like `try_trait_v2`, `type_alias_impl_trait`, `const_trait_impl`, etc.
+- `platform-mem` dependency uses unstable `allocator_api`, `try_blocks`, and other unstable features
+- The main `doublets` crate itself uses many unstable features
+
+## Solution Applied
+
+### 1. Fixed unstable features in `platform-data` dependency
+- Removed unstable feature flags from `dev-deps/data-rs/src/lib.rs`
+- Replaced `const` trait implementations with regular implementations in `link_type.rs`
+- Removed `~const` trait bounds in `hybrid.rs` and `converters.rs`
+- Fixed `type_alias_impl_trait` usage in `point.rs` with concrete iterator type
+- Simplified `flow.rs` by removing unstable `Try` trait implementation
+
+### 2. Updated main crate configuration
+- Disabled unstable features in `doublets/src/lib.rs`
+- Fixed import issues: `std::default::default` → removed where not needed
+- Removed `allocator_api` feature from `bumpalo` dependency
+- Temporarily disabled `mem` and `trees` dependencies due to extensive unstable feature usage
+
+### 3. Build Status
+After these changes, the project compiles with stable Rust, though some functionality is reduced due to disabled dependencies.
+
+## Recommendations for Complete Fix
+
+1. **Update Dependencies**: The project should pin to stable versions of platform dependencies that don't use unstable features, or create stable-compatible forks.
+
+2. **Feature Gates**: Consider making unstable features optional behind feature flags that default to stable implementations.
+
+3. **Alternative Implementations**: Replace unstable features with stable alternatives where possible.
