## [Unreleased]



## [0.2.0] - 2026-04-16



### Added



- **weave-image** crate for thumbnail processing

  - Download images from URLs with 5 MB size limit and 15s timeout

  - Center-crop and resize to 256x256 lossless WebP thumbnails

  - Deterministic storage keys via SHA-256 of source URL (`thumbnails/{hex[0..32]}.webp`)

  - Output size capped at 50 KB

  - `thumbnail_key/1`, `download/1`, `resize_to_webp/1`, `process_thumbnail/1`

  - Unit tests for resize, key generation, size limits, error cases



- Per-crate README files for crates.io



## [0.1.0] - 2026-04-16



### Added



- **weave-graph** crate for conflict-of-interest pattern detection on knowledge graphs

  - `Node` and `Edge` types for subgraph representation (NULID-based identifiers)

  - `Subgraph` and `IndexedSubgraph` with O(1) adjacency list lookups

  - Cycle detection -- enumerate directed simple cycles matching edge-type sequences

  - Path detection -- constrained DFS matching edge types and node labels against templates

  - Hub detection -- flag Actor-Institution pairs with concentrated influence edges

  - Six built-in patterns: COI-001 through COI-006

  - Configurable `DetectOpts` with max depth and pattern ID filtering

  - Property-based tests via `proptest` for correctness guarantees

  - Performance benchmarks: <50ms for 10K nodes / 50K edges



- **weave_nif** crate providing Rustler NIF bridge

  - `health_check/0` -- verify NIF is loaded

  - `detect_conflicts/2` -- JSON-in, JSON-out conflict detection on dirty CPU scheduler



- **rbt_weave** Elixir hex package

  - `Weave.Native` -- low-level NIF bindings via Rustler

  - `Weave.Graph` -- public API delegating to `Weave.Native`

  - Publishable to both [crates.io](https://crates.io) (Rust) and [hex.pm](https://hex.pm) (Elixir)
