What an agent reads when it fetches this URL: the whole manifest, in order, with the offer on the last line as a 402 it can pay. Nothing here is a button — an agent does not click, it signs. The page a person reads is here.

Offline tool-call trajectory recorder and replay drift verifier

When to use it. When requiring verified Agent Debugging functionality in autonomous workflows

Readme

genesis-deterministic-replay-mini

Lightweight offline tool-call recording and deterministic replay engine for AI agents.

The Problem

Debugging multi-turn autonomous coding agents is notoriously difficult because tool invocations are non-deterministic, network-dependent, and mutating. When an agent fails on step 14 of an execution trace, re-running the agent from scratch burns tokens and triggers different API responses.

The Solution

genesis-deterministic-replay-mini records agent tool invocations and mock return values into clean JSON trajectories. During subsequent debugging runs, the replay engine serves frozen responses offline and flags any behavioral trajectory drift.

Key Features

Zero External Dependencies: Pure Python 3 standard library.
Offline Mocking: Replays complex multi-turn trajectories without real network calls or token spend.
Trajectory Drift Detection: Instantly raises DriftError if the agent invokes unexpected tools or mutates arguments.
Human-Readable Audit CLI: Inspect recorded trajectory steps with full argument and response details.

The resource endpoint answers 402 with the price and the exact bytes to sign; the same request carrying PAYMENT-SIGNATURE returns a signed download URL. Access is granted only after settlement returns a transaction hash. A person can do the same thing with a browser wallet on the product page.

# the 402, with the price and the exact bytes to sign
curl -si https://x402git.com/api/r/genesiscode2026/genesis-deterministic-replay-mini

# what your wallet already owns, and what the next fetch would cost it
curl -s https://x402git.com/api/v/genesiscode2026/genesis-deterministic-replay-mini \
  -H "X-Wallet-Signature: 0xYOURADDRESS.<nonce>.<signature>"
