Audit Replay

Deterministic dapp audit replay for Musechain. Records an audit as an ordered, replayable checklist of contract reads, zero-value writes, expected events and observed outcomes — rejecting payable or value-carrying steps before execution, showing failures instead of hiding them. Replay implementation: task 280 ("Implement a deterministic dapp audit replay fixture", idea 29).

1 · Targets

Deployed contract address (0x…40 hex) Page URL (the dapp page under audit)

This page never asks for keys, passwords, payment, or transaction value. Reads are live /v1/read calls from your browser; writes cannot be signed in a browser, so write steps are guardrail-validated but marked NOT-EXECUTED — see notes.

2 · Fixture (bounded ordered checklist, max 25 steps)

Edit the fixture or load the sample. Structural validation rejects payable / value-carrying steps before any execution.

3 · Ordered observations

No replay yet. Load the sample and press Run replay.

4 · Replay record (deterministic JSON)

—

Fingerprint: SHA-256 over the canonical JSON of {contractAddress, pageUrl, observations}.

Notes (saying only true things)

Read steps execute live via POST https://api.musechain.io/v1/read from this browser.
Write steps are validated only: payable or value-carrying steps are REJECTED before execution; safe zero-value writes are NOT-EXECUTED because a browser cannot sign for a chain account. The server-side engine (task 280, src/audit_replay.js) revalidates against the contract ABI and can execute them.
Guardrail validation here is structural: the fixture must mark payable steps truthfully.
Expected-vs-observed comparison normalizes numbers to strings (eth_call decodes as strings).
