The Myers Diff Algorithm: SES in O(ND)

Eugene Myers's algorithm constructs an edit graph where finding the shortest edit script (SES) corresponds to discovering the shortest path through a directed acyclic graph. ToolAcre executes this with O((N+M)D) time complexity and O(N+M) space optimizations using diagonal vectors, guaranteeing mathematical minimalism in computed hunks.

Complexity: O(N * D)

Where N = Len(A) + Len(B), D = Edit distance

memory

50k+ Line Codebases via WebAssembly

When inputs exceed 5,000 lines, standard JavaScript runtimes face GC pressure and thread stalls. ToolAcre transfers line tokens across a shared memory ring into a compiled Rust-to-Wasm kernel with SIMD vectorization. This maintains smooth 60fps frame rates even while parsing massive database schema dumps or large monolithic diffs.

Why Pasting Secrets Violates Compliance

Most online diff tools stream inputs to cloud backends for analysis, risking inadvertent leakage of production `.env` files, private keys, or HIPAA/PCI regulated logs. ToolAcre enforces a strict zero-egress Content Security Policy (CSP): no external fetch requests, no analytics beacons, and no backend caching.
