Signed, independently checkable receipts for Hermes approval verdicts and, since 0.2.0, for turns that stop on iteration exhaustion. Observe-only: a post_approval_response hook requests an invinoveritas decision receipt for each Guardian LLM verdict (or every approve/deny with scope=all); post_llm_call + on_session_end record, when a turn ends with max_iterations_reached, whether the turn's todo ledger (the last todo result or the list re-injected after compaction) was complete (turn_scope: exhausted by default, all, or off). Each receipt is a signed set of salted commitments that anyone can check for free at /verify-proof and that the holder can later open with the salt kept locally. Never approves, denies, delays, continues or blocks anything.

## Good to know before installing

One HTTPS POST per recorded approval decision or recorded turn to api.babyblueviper.com/decision-receipt (or the configured api_url) under INVINOVERITAS_API_KEY, paid automatically at 100 sats per receipt from your invinoveritas balance with no per-call confirmation (defaults: Guardian LLM verdicts, and only turns that stop on max_iterations_reached; scope: all adds every human approve/deny, turn_scope: all pays on every turn); sends a fixed question, the options, the choice, a nonce-salted SHA-256 of the context and the tool_call_id/turn_id, never the command text, todo contents or reply text; stores receipts, salts and the full contexts (including the command as Hermes passed it, and the todo ledger) in plugin-data/invinoveritas-receipts/receipts.jsonl.

From the plugin's catalog listing.

## How to install

1. Install it. Hermes asks for any API keys it needs (this one needs `INVINOVERITAS_API_KEY`), then asks whether to turn it on.

```bash
hermes plugins install invinoveritas-receipts
```

2. Said no? Turn it on later:

```bash
hermes plugins enable invinoveritas-receipts
```

3. Restart Hermes so it loads the plugin.

Some plugins also need a sign-in or settings: see the official page. Memory plugins ask whether to become your memory provider instead. Steps follow the official plugins guide: https://hermes-agent.nousresearch.com/docs/user-guide/features/plugins
