Persistent memory for Hermes. Canonicalizes duplicate memories, surfaces contradictions between structured or recognized single-valued claims for review, and returns a why_retrieved reason list with every recall. Embedded by default: no server, no token, no GPU. Optional HTTP backend for HA clusters; pluggable embedders (bundled potion-2M default).

## How to install

1. Install it. Hermes asks for any API keys it needs, then asks whether to turn it on.

```bash
hermes plugins install yantrikdb
```

2. Said no? Turn it on later:

```bash
hermes plugins enable yantrikdb
```

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
