+
+## Current Diff Flow
+
+1. `capture_diff_slices(alg, &old, &new)` → `Vec<DiffOp>`
+2. `DiffOp::iter_changes(&old, &new)` → `Iterator<Change<T>>`
+3. Requires `T: Hash + Eq + Ord`
+
+## Key Types
+
+```rust
+pub enum DiffOp {
+    Equal { old_index: usize, new_index: usize, len: usize },
+    Delete { old_index: usize, old_len: usize, new_index: usize },
+    Insert { old_index: usize, new_index: usize, new_len: usize },
+    Replace { old_index: usize, old_len: usize, new_index: usize, new_len: usize },
+}
+
+pub struct Change<T> {
+    pub(crate) tag: ChangeTag,
+    pub(crate) old_index: Option<usize>,
+    pub(crate) new_index: Option<usize>, 
+    pub(crate) value: T,
+}
+```
+
+## Algorithm Trait
+
+```rust
+pub trait DiffHook {
+    type Error;
+    fn equal(&mut self, old: usize, new: usize, len: usize) -> Result<(), Self::Error>;
+    fn delete(&mut self, old: usize, old_len: usize, new: usize) -> Result<(), Self::Error>;
+    fn insert(&mut self, old: usize, new: usize, new_len: usize) -> Result<(), Self::Error>;
+    fn replace(&mut self, old: usize, old_len: usize, new: usize, new_len: usize) -> Result<(), Self::Error>;
+}
+```
+
+## Task: FP Comparison
+
+Add eps/ulps floating point comparison for f32/f64 slices.
+
+### Implementation Points
+
+1. **New comparison trait** alongside existing `PartialEq` requirement
+2. **Algorithm modification** to use FP-aware comparison in core loops
+3. **API surface** for specifying epsilon/ulps parameters  
+4. **Testing** edge cases: NaN, infinity, subnormals, precision boundaries
+
+### Files to Modify
+
+- `src/algorithms/myers.rs` - Core comparison logic
+- `src/algorithms/patience.rs` - Core comparison logic  
+- `src/algorithms/lcs.rs` - Core comparison logic
+- `src/common.rs` - Add FP-aware `capture_diff_slices_fp()`
+- `examples/floating_point.rs` - Usage demonstration
+
+### Example Usage Goal
+
+```rust
+let old = vec![1.0, 2.0, 3.0];
+let new = vec![1.000001, 2.0, 3.1];
+
+// Absolute epsilon
+let ops = capture_diff_slices_fp_eps(Algorithm::Myers, &old, &new, 0.0001);
+
+// Relative ulps  
+let ops = capture_diff_slices_fp_ulps(Algorithm::Myers, &old, &new, 4);
+```
+
+### Testing Strategy
+
+Use existing `insta` snapshot testing framework. Test matrices:
+- Normal values with various epsilon/ulps settings
+- Edge cases: ±0.0, NaN, ±infinity
+- Precision boundaries and subnormal values
+- Mixed normal/edge case arrays
+
+### Status
+
+- [x] CI fixed (Rust 1.66 MSRV)
+- [x] Codebase analysis complete
+- [ ] Design FP comparison API
+- [ ] Implement core FP comparison logic
+- [ ] Add comprehensive tests
+- [ ] Create usage examples
