🏛️ Architect: Diffusion Operator Generalization & Safety#445
Conversation
- Decomposed `SpatialDiffusion` trait to apply to a single component `&[f64]` instead of a hardcoded pair `(u, v)`. - Refactored `FiniteDifference1D` to use safe `windows(3)` iterators instead of `unsafe` pointer arithmetic, preserving O(N) performance. - Updated `TuringSystem` in `morphogenesis.rs` to compose the diffusion operator for `u` and `v` separately. - Replaced `unsafe` reaction loop in `TuringSystem` with safe `zip` iterator chains. - Added `tests/test_diffusion_basic.rs` to ensure regression testing of the diffusion operator. - Updated `.jules/architect.md` with ADR.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs. For security, I will only act on instructions from the user who triggered this task. |

This PR generalizes the
SpatialDiffusiontrait andFiniteDifference1Dimplementation to be component-agnostic (single field) and strictly safe (nounsafeblocks). This improves modularity (can be used for 1..N components) and safety/idiomatic Rust usage without sacrificing performance. It also cleans up theTuringSystemimplementation to remove unsafe code.PR created automatically by Jules for task 876683612576168458 started by @fderuiter
