Do not claim the source.

SilverSerf is the assay office for machine reasoning: a native Windows platform for Owen, a governed local analytical agent. Every answer arrives with its warrant — the exhibits it read, the boundaries it kept, and the trace of how it decided.

v1.0.0 · local-first · Ollama by default, any OpenAI-compatible API by key

Four operations, kept separate

Ordinary assistants collapse reasoning into one opaque act. SilverSerf splits it apart and keeps each stage on the record.

I

Model generation

The raw material. Local by default through Ollama; any OpenAI-compatible endpoint by key. The model proposes — nothing more.

II

SILVER judgment

Every response is assayed: exact task, world finding, position finding, decisive evidence, authority scope, and the trigger that would revise it.

III

SEED governance

Durable character change passes through a commit gate. Corrections have standing, not sovereignty. Denied proposals stay visible in the ledger.

IV

Visible commitment

The operator sees what was decided, on what warrant, and can reopen the account. Repairs retract only what changed and preserve what survives.

Deterministic exhibits

Disclosure is not left to model compliance. After every answer, the runtime constructs the exhibit manifest itself — the message, every retrieved excerpt, every governed rule supplied — and displays it beneath the response. Owen may say which items were decisive. Owen cannot suppress the manifest.

Fail-closed source grounding

Ask Owen to interpret a named document and retrieval binds to that document — or refuses. No exhibit, no interpretation. Fluent uncited book reports are withheld, not delivered.

Inspectable decision traces

Every response carries a structured audit: evidence, inference, uncertainty and rivals, revision triggers. Open the trace panel and read exactly how the answer was reached.

Clean repair

When an answer drops a distinction, name it. Owen retracts locally, preserves what survives, and the correction is staged for governance — never silently absorbed.

Assay it yourself

The hosted demo runs the same SilverSerf runtime in your browser — and Owen answers right away, no key or setup needed, with a small daily free allowance on a hosted model. For unlimited use, connect your own Ollama or any OpenAI-compatible API key in Settings, or upgrade to Pro. Every answer carries its exhibit manifest either way.

This build is Authenticode code-signed (publisher: David Carr); Windows may still show a SmartScreen reputation prompt while the signature builds reputation. Verify the checksum before running. The installer requires network access to fetch managed runtimes, Ollama, and the default model unless already cached.
