SettlementWitness

Verify structured agent task outputs and return signed proof of outcome.

Core Principle

Verification should be deterministic, minimal, and optional.

Only structured inputs are evaluated.

What This Does

SettlementWitness evaluates submitted task data and returns:

PASS / FAIL / INDETERMINATE
signed receipt (SAR)
optional TrustScore update

Core Execution Loop

Provide input:
- task_id
- optional agent_id
- spec (expected result)
- output (actual result)
Submit for verification
Receive:
- verdict
- receipt
- optional score update

Example

settlement_witness({ task_id: "task-001", agent_id: "0xYourWallet:agent", spec: { expected: "report generated" }, output: { expected: "report generated" } })

Result Structure

{ "verdict": "PASS | FAIL | INDETERMINATE", "receipt_id": "sha256:...", "signature": "...", "confidence": 1.0 }

signature-based (Ed25519)

What This Is Not

not a payment system
not data storage
not enforcement layer

What This Is

deterministic verifier
receipt generator
proof system
reputation input layer

Outcome

Agents can:

prove task completion
generate verifiable records
build reputation over time
