Summary

This PR introduces ruvector-robotics, a comprehensive cognitive robotics platform that integrates with ruvector's vector database, graph neural networks, and self-learning infrastructure. The new crate provides a complete robotics stack spanning perception, planning, cognitive architecture, and multi-robot coordination.

Key Changes

Core Bridge Module (crates/ruvector-robotics/src/bridge/)

  • Core types: Point3D, PointCloud, RobotState, Pose, Trajectory, SceneGraph, OccupancyGrid
  • Spatial indexing: Flat-vector SpatialIndex with brute-force kNN/radius search supporting Euclidean, Manhattan, and Cosine distance metrics
  • Gaussian splatting: GaussianSplat representation for point cloud visualization with position, color, opacity, and scale
  • Perception pipeline: Lightweight sensor frame ingestion with obstacle detection and trajectory prediction
  • Type converters: Bidirectional conversions between domain types and flat vector representations

Perception Subsystem (crates/ruvector-robotics/src/perception/)

  • Obstacle detection: Spatial-hash clustering with classification (Static/Dynamic/Unknown)
  • Scene graph construction: Builds structured object relationships from point clouds using union-find clustering
  • Sensor fusion: Multi-sensor point cloud alignment and merging with confidence weighting
  • Clustering utilities: Shared spatial-hash clustering with union-find for obstacle and scene graph modules

Cognitive Architecture (crates/ruvector-robotics/src/cognitive/)

  • Behavior trees: Composable nodes (Sequence, Selector, Action, Condition) with decorators (Invert, Repeat, Timeout)
  • Memory system: Three-tier architecture (working, episodic, semantic) with bounded buffers and similarity search
  • Decision engine: Multi-criteria utility-based action selection using reward, risk, energy, and novelty
  • Skill learning: Learning from demonstration with trajectory generalization and confidence tracking
  • World model: Object tracking, occupancy grid maintenance, and linear state prediction
  • Cognitive core: Central perceive→think→act→learn loop with mode switching (Reactive/Deliberative/Learning)
  • Swarm coordination: Formation computation, capability-based task assignment, and majority consensus

MCP Integration (crates/ruvector-robotics/src/mcp/)

  • Tool registry: Schema-free MCP tool definitions with JSON schema generation
  • Tool executor: Stateful executor wiring perception pipeline, spatial index, and memory to tool requests
  • Categories: Perception, Planning, Manipulation, Navigation, Learning tool categories

Planning Module (crates/ruvector-robotics/src/planning.rs)

  • A grid search*: Discrete pathfinding on occupancy grids with heuristic-guided search
  • Potential field: Continuous-space repulsive/attractive field velocity commands

Domain Expansion (crates/ruvector-robotics/src/domain_expansion.rs)

  • Implements ruvector_domain_expansion::Domain trait for cross-domain transfer learning
  • Task categories: PointCloudClustering, ObstacleAvoidance, SceneGraphConstruction, SkillSequencing, SwarmFormation
  • Synergy mapping between robotics, planning, tool orchestration, and Rust synthesis domains

RVF Packaging (crates/ruvector-robotics/src/rvf.rs)

  • Bridges robotics types with RuVector Format for persistence and querying
  • Supports packing/unpacking point clouds, scene graphs, Gaussian splats, and occupancy grids

Testing & Benchmarking

  • Integration tests (tests/robotics_integration.rs, tests/integration.rs): Full pipeline validation across bridge, perception, cognitive, and MCP modules
  • Comprehensive benchmarks (benches/robotics_benchmarks.rs): 1247-line benchmark suite covering point cloud conversion, spatial search, obstacle detection, trajectory prediction, attention computation, behavior tree execution, scene graph construction, episodic memory recall, full perceive→think→act pipeline, and swarm task assignment

feat: Add agentic-robotics crates and SOTA integration research
8730ea6 
Copy 6 agentic-robotics crates (core, rt, mcp, embedded, node, benchmarks)
into ruvector/crates/ for deep integration review. These provide:
- ROS3 pub/sub messaging with Zenoh middleware and CDR serialization
- Dual-runtime real-time executor with priority scheduling
- MCP 2025-11 server for AI tool exposure
- NAPI-RS Node.js bindings
- Criterion benchmark suite

Create comprehensive research documentation in docs/research/agentic-robotics/:
- README.md: SOTA integration analysis (889 lines)
- crate-review.md: Crate-by-crate deep code review (967 lines)
- architecture-synergy.md: Architecture compatibility analysis (555 lines)
- integration-roadmap.md: 18-week phased implementation plan (769 lines)

Key findings: 14/16 shared dependencies are version-compatible, both use
rkyv 0.8 for zero-copy serialization, identical build profiles, and
complementary (not overlapping) functionality. The combination creates a
unique cognitive robotics platform with sub-millisecond sensor-to-decision
latency, native vector search, GNN inference, and MCP tool exposure.

…gnitive, and MCP modules

Consolidates robotics functionality into a single crate with four modules:
- bridge: Core types (Point3D, PointCloud, RobotState, Pose), spatial indexing,
  distance metrics, sensor converters, and perception pipeline
- perception: Scene graph construction, obstacle detection/classification,
  anomaly detection, trajectory prediction, and attention focusing
- cognitive: Behavior trees, perceive-think-act-learn loop, multi-criteria
  decision engine, three-tier memory system, skill learning from demonstration,
  swarm coordination with formations/consensus, and world model tracking
- mcp: Tool registry with 15 registered tools across 6 categories

Includes 26 passing tests (10 unit + 15 integration + 1 doc), 5 crate examples,
10 standalone binary examples, benchmarks covering 10 groups, and user guide.

fix: restore HashMap import in scene_graph after clustering extraction
d29e9b2 
The DRY refactor that extracted shared clustering code accidentally
removed the HashMap import still needed by merge_scenes.

…ross-domain transfer

Performance optimizations (net -134 lines):
- BinaryHeap kNN: O(n log k) vs O(n log n) full sort in SpatialIndex
- Zero-clone behavior tree tick via pointer-based borrow splitting
- VecDeque percept buffer for O(1) front eviction
- HashSet assigned_robots for O(1) membership checks
- Shared clustering module eliminates 3 duplicate implementations

Correctness fixes:
- UntilFail decorator 10k iteration guard prevents infinite loops
- OccupancyGrid bounds-checked get() returns Option<f32>
- Pipeline position_history capped at 1000 entries
- Skill learning gracefully handles empty demonstrations
- Anomaly type gets Serialize/Deserialize derives

Dead code removal:
- Remove unused TrajectoryPoint struct
- Remove unused tracing and rand dependencies

Domain expansion integration (behind `domain-expansion` feature flag):
- RoboticsDomain implements domain::Domain trait with 5 task categories:
  PointCloudClustering, ObstacleAvoidance, SceneGraphConstruction,
  SkillSequencing, SwarmFormation
- 64-dim embedding space compatible with planning/orchestration/synthesis
- Reference solutions, difficulty scaling, cross-domain transfer tests
- Enables Meta Thompson Sampling transfer between robotics and
  existing domains (Rust synthesis, structured planning, tool orchestration)

All 257 tests pass (231 unit + 25 integration + 1 doc-test).

fix: address critical and high-priority issues from deep code review
3353ba2 
- Remove unsafe pointer aliasing in BehaviorTree::tick(), use safe
  disjoint field borrowing instead (P0)
- Fix usize underflow in score_scene_graph when expected_objects < 2 (P0)
- Fix cluster ID overflow in reference_solution for PointCloudClustering (P0)
- Fix NaN handling in MaxDistEntry::cmp — NaN treated as maximally
  distant so it gets evicted from kNN heap first (P1)
- Clamp cosine_distance output to prevent negative values from
  floating-point rounding (P1)
- Change search_radius to return Ok(Vec::new()) for empty index instead
  of Err(EmptyIndex) for correct semantics (P1)
- Add debug_assert guards for empty slices in bounding_sphere and
  cluster_to_object (P1)
- Remove dead PipelineConfig.spatial_search_k field (P2)
- Use serde_json::from_value instead of to_string+from_str roundtrip
  in domain_expansion for better performance (P2)

All 257 tests pass.

…usion, and benchmarks

New modules for ruvector-robotics:
- bridge/gaussian: GaussianSplat types, PointCloud→Gaussian conversion, vwm-viewer JSON export
- planning: A* pathfinding on OccupancyGrid with octile heuristic, potential field velocity commands
- mcp/executor: ToolExecutor dispatching ToolRequests to perception pipeline and spatial index
- perception/sensor_fusion: multi-sensor cloud fusion with timestamp alignment and voxel downsampling

Rewrites integration tests to use actual crate APIs instead of local reimplementations,
eliminating ~280 lines of false-positive test code. Adds 15 benchmark groups covering
all new modules (Gaussian conversion, A* planning, potential fields, sensor fusion, MCP execution).

All 270+ tests pass including domain-expansion feature.

feat: add RVF packaging module for robotics data
2a7068b 
New `rvf` feature flag enables the `ruvf::RoboticsRvf` wrapper that
bridges point clouds, scene graphs, trajectories, Gaussian splats, and
obstacles into the RuVector Format (.rvf) for persistence and similarity
search.

RoboticsRvf supports:
- pack_point_cloud (dim 3)
- pack_scene_objects / pack_scene_graph (dim 9)
- pack_trajectory (dim 3)
- pack_gaussians (dim 7) — converts PointCloud→GaussianSplatCloud→RVF
- pack_obstacles (dim 6)
- query_nearest (kNN via HNSW index)
- open/open_readonly/close lifecycle

9 unit tests covering create, ingest, query, reopen, dimension mismatch,
and empty data rejection. Also fixes unused import warnings in integration
tests. All 290 tests pass across default, domain-expansion, and rvf features.

perf: optimize hot paths across indexing, clustering, planning, and p…

…erception

SpatialIndex: replace Vec<Vec<f32>> with flat Vec<f32> buffer for cache
locality and zero per-point heap allocation; use squared Euclidean
distance in kNN/radius search (defer sqrt to final k results); fuse
cosine distance into single loop.

Clustering: add union-by-rank to union-find preventing tree
degeneration (O(α(n)) amortized); add #[inline] on hot helpers.

A* planning: add closed set (HashSet) to avoid re-expanding nodes;
reuse neighbor buffer to eliminate per-expansion Vec allocation;
pre-allocate HashMap capacity; add #[inline] on helpers.

Perception: defer sqrt in bounding_sphere (compare squared distances,
one sqrt at end); defer sqrt in scene graph edge construction (filter
on squared threshold); add #[inline] on dist_3d.

Sensor fusion: pre-allocate merged vectors from total eligible cloud
size. Anomaly detection: fuse distance + statistics into single pass
using Welford's online algorithm (eliminates one full data pass).

All 281 tests pass.

fix: resolve clippy warnings and P0 issues in ruvector-robotics
f85ac08 
Clippy fixes (8 warnings → 0):
- Replace 5 manual Default impls with #[derive(Default)]
- Use .clamp() instead of .min().max() chain
- Use .is_some_and() instead of .map_or(false, ...)

P0 correctness fixes from code review:
- Fix NaN panic: use unwrap_or(Ordering::Equal) in cognitive_core think()
- Fix integer overflow: use checked_mul in OccupancyGrid::new
- Fix potential unwrap: use map_or in domain_expansion score_avoidance
