12 .NET libraries · one shared foundationThese aren't twelve unrelated packages. Phasor is the vector-symbolic core — the holographic math. EvalApp is the runtime that schedules and self-tunes the heavy work. HoloDb, AlgFormer, Tracer, and HoloVoxel are what you get when you build a database, a transformer, a game-AI SDK, and a spatial engine on that same foundation — and the rest extend those four. Four of these libraries also power the tools live on the homepage right now; every one of the twelve is real, shipped, and on NuGet today.
the base everything shares
Vector-symbolic computing for .NET. Bind, bundle, and unbind hyperdimensional / phasor (HRR) vectors with a SIMD codec — the holographic primitive the rest of these libraries are built on.
dotnet add package EvaluatedApplications.PhasorAn async pipeline runtime: resource-gated concurrency with adaptive self-tuning, sagas with compensation, middleware, and a fluent builder. The shared execution engine underneath the other libraries.
One in-process dependency in place of a DI container + MediatR + Polly + TPL Dataflow. See how it works →
dotnet add package EvaluatedApplications.EvalAppa holographic SQL database, embedded or networked
An embeddable holographic database: data stored as one associative store and queried three ways over
one copy — exact SQL by key, similarity by content (NEAREST), and constant-time aggregates. Real ACID
with a write-ahead log, and a durable, larger-than-memory paged engine that spills to disk.
On a 10,000,000-invoice ledger joined to 200,000 customers, the dashboard rollups read in microseconds in the embedded engine. Same SQL, same data, every result identical across SQLite, DuckDB, SQL Server and HoloDb; one run on one machine, in memory, with the queries where HoloDb is slower shown. See the benchmarks →
dotnet add package EvaluatedApplications.HoloDbThe .NET client for a remote HoloDb server. Connect over TLS with a token, then run SQL and bulk-load with the same surface as the in-process engine. Columnar results stay columnar on the wire.
dotnet add package EvaluatedApplications.HoloDb.ClientThe HoloDb wire contract: length-prefixed TCP framing and a columnar-preserving codec. Normally pulled in transitively by the client — you rarely reference it directly.
dotnet add package EvaluatedApplications.HoloDb.Protocola holographic transformer, a self-tuning brain for it, and a corpus generator
A transformer engine for .NET with two interchangeable attention cores — classic softmax and a holographic core built on the Phasor codec. Dependency-free and AOT / trim-safe, no native baggage.
The holographic core writes meaning as chords, not points. How it works →
dotnet add package EvaluatedApplications.AlgFormerOptional ILGPU / CUDA acceleration for AlgFormer: batched GPU forward + backward training and GPU inference, with automatic CPU fallback when no CUDA device is present. The core stays dependency-free.
dotnet add package EvaluatedApplications.AlgFormer.GpuA tiny, always-learning neural policy that plugs into EvalApp's concurrency tuner in place of the heuristic — ships warm, keeps learning live, and adapts to workloads that shift or couple resources.
dotnet add package EvaluatedApplications.EvalApp.NeuralThe AlgFormer/HoloFormer production standard: a stamped, append-only lineage journal for a growing model, plus the canonical confidence-gated decode policy a real production host runs.
dotnet add package EvaluatedApplications.PrismA grammar-driven synthetic corpus generator: mines real text with deterministic rules into a HoloDb database, then recombines it into new, grammatical, plausible sentences and Q&A pairs.
dotnet add package EvaluatedApplications.Prosemovement, tactics, and voxels
A pathfinding and game-AI SDK: navmesh pathfinding, multi-agent scheduling, dynamic obstacles, line-of-sight, fog-of-war, influence maps, and grid tactics. Headless, and parallel on the EvalApp runtime.
dotnet add package EvaluatedApplications.TracerA holographic voxel engine: level-of-detail-native spatial storage on the Phasor codec, SIMD throughout, with procedural generation. Near data stays crisp, far data degrades gracefully.
dotnet add package EvaluatedApplications.HoloVoxelThese aren't twelve unrelated packages. Phasor is the vector-symbolic core — the holographic math. EvalApp is the runtime that schedules and self-tunes the heavy work. HoloDb, AlgFormer, Tracer, and HoloVoxel are what you get when you build a database, a transformer, a game-AI SDK, and a spatial engine on that same foundation — and the rest extend those four: HoloDb.Client/HoloDb.Protocol put HoloDb on the network, AlgFormer.Gpu puts AlgFormer's holographic core on a GPU, EvalApp.Neural swaps EvalApp's tuner for a learned one, Prism is the stamped lineage journal and decode policy a production AlgFormer/HoloFormer host runs, and Prose uses HoloDb and AlgFormer together to grow a training corpus.
the same terms on every package
Proprietary — every package ships the compiled library only; see each package's own LICENSE
on NuGet for the full terms. Installing and using unmodified copies for internal evaluation and non-commercial
development or testing is licensed; commercial, production, or revenue-generating use requires a separate
commercial licence from the owner. No feature described on this site is gated behind a tier or a licence key —
every capability works identically with or without one.
