# OpenClaw Ledger

Tamper-evident audit trail for agent workspaces. Every workspace change is recorded in a hash-chained log — if anyone alters an entry, the chain breaks and you know.

## The Problem

Agents modify files, execute commands, install skills — and leave no verifiable record. If something goes wrong, you can't trace what happened. If logs exist, nothing proves they haven't been altered after the fact.


## Commands

### Initialize

Create the ledger and snapshot current workspace state.

```bash
python3 {baseDir}/scripts/ledger.py init --workspace /path/to/workspace
```

### Record Changes

Snapshot current state and log all changes since last record.

```bash
python3 {baseDir}/scripts/ledger.py record --workspace /path/to/workspace
python3 {baseDir}/scripts/ledger.py record -m "Installed new skill" --workspace /path/to/workspace
```

### Verify Chain

Verify the hash chain is intact — no entries tampered with.

```bash
python3 {baseDir}/scripts/ledger.py verify --workspace /path/to/workspace
```

### View Log

Show recent ledger entries.

```bash
python3 {baseDir}/scripts/ledger.py log --workspace /path/to/workspace
python3 {baseDir}/scripts/ledger.py log -n 20 --workspace /path/to/workspace
```

### Quick Status

```bash
python3 {baseDir}/scripts/ledger.py status --workspace /path/to/workspace
```

## How It Works

Each entry contains:
- Timestamp
- SHA-256 hash of the previous entry
- Event type and data (file changes, snapshots)

If any entry is modified, inserted, or deleted, the hash chain breaks and `verify` detects it.

## Exit Codes

- `0` — Clean / chain intact
- `1` — No ledger or minor issues
- `2` — Chain tampered / corrupt entries

## No External Dependencies

Python standard library only. No pip install. No network calls. Everything runs locally.

## Cross-Platform

Works with OpenClaw, Claude Code, Cursor, and any tool using the Agent Skills specification.
