Adp.Manifest

A .NET 10 reference implementation of the Agent Deliberation Protocol (ADP) specification — the consensus protocol that multi-agent systems use to reach calibrated, falsifiable decisions together. ADP defines proposals, weights, tallies, falsification, termination, and reversibility tiers.

This library is one of several reference implementations (TypeScript, Python) of the same spec. The spec itself is at adp-manifest.dev and is the source of truth; this library implements what the spec says.

Zero runtime dependencies beyond System.Collections.Immutable.

Looking for a runnable agent? This library is the protocol core — data types, weighting math, and an in-memory orchestrator. For a full federation-ready agent runtime with HTTP endpoints, journal persistence, Ed25519 signing, signed calibration snapshots, ACB pricing, and MCP integration, install Adp.Agent instead.

Install

dotnet add package Adp.Manifest

Packages are published to the Gitea NuGet feed at https://git.marketally.com/api/packages/ai-manifests/nuget/index.json. Configure once in your project's nuget.config:

  </packageSources>
</configuration>

Or clone and build from source:

git clone https://github.com/ai-manifests/adp-ref-lib-csharp.git
cd adp-ref-lib-csharp
dotnet build

Quick example

using Adp.Manifest;

var proposal = new Proposal(
    AgentId: "did:adp:test-runner-v1",
    Domain: "code.correctness",
    Vote: Vote.Approve,
    Confidence: 0.82,
    Stake: new Stake(Magnitude: StakeMagnitude.Medium, Domain: "code.correctness"),
    Justification: new Justification(Rationale: "all tests pass", EvidenceRefs: []),
    DissentConditions: []
);

var calibration = new CalibrationScore(Value: 0.78, SampleSize: 42);
double weight = WeightingFunction.ComputeWeight(proposal, calibration);
// weight ≈ 0.82 × 0.78 × StakeFactor(Medium) × ApplySampleSizeDiscount(42)

API

All public types live in the Adp.Manifest namespace.

Enums

Vote, ReversibilityTier, DissentConditionStatus, TerminationState, StakeMagnitude

Records

Amendment, DissentCondition, VoteRevision, ProposalAction, BlastRadius, DomainClaim, Justification, Stake, Proposal, TallyResult

Weighting

WeightingFunction — static class with:

• ComputeWeight(proposal, calibration) — canonical proposal weight per ADP §4.2
• ComputeDecay(age, halfLife) — time decay of calibration evidence
• StakeFactor(magnitude) — maps StakeMagnitude to its numeric factor
• ApplySampleSizeDiscount(value, sampleSize) — Wilson-interval sample-size discount

Orchestration

• DeliberationConfig — record describing a deliberation's rules (thresholds, participants, tiers)
• AgentRegistration — record for a participating agent
• DeliberationSnapshot — record for a point-in-time state of a running deliberation
• DeliberationOrchestrator — in-memory state machine that runs a deliberation through proposal → tally → falsification → termination. Intended for prototypes, tests, and embedded-in-process use. For production distributed deliberation, see Adp.Agent.

Calibration source

• ICalibrationSource — interface the orchestrator uses to look up per-agent calibration scores. Implementations can back this with in-memory state, a local journal, or a remote registry.

Testing

dotnet test

Spec

This library implements the Agent Deliberation Protocol specification. Read the spec at adp-manifest.dev. If the spec and this library disagree, the spec is correct and this is a bug.
