# Deploy and Host Hippocamp Dream with Railway

Run Hippocamp's memory compaction overnight without keeping your computer awake. This template creates a scheduled Railway service that clones your private Lagoon memory repository, compacts projects over the configured wake-up threshold, and opens one reviewable pull request per project.

## About Hosting Hippocamp Dream

The service runs once per day at `03:17 UTC` and exits after it finishes. Each run starts from a fresh clone, writes only `current_state.md` and `open_threads.md`, and leaves append-only events untouched. GitHub remains the audit trail and review surface; Railway only hosts the scheduled job.

## Required Configuration

- `LAGOON_REPOSITORY`: your private memory repository in `owner/repository` form
- `GITHUB_TOKEN`: a fine-grained GitHub token limited to that repository, with Contents and Pull requests read/write access
- `MANIFEST_BASE_URL`: a Manifest or OpenAI-compatible Responses API base URL
- `MANIFEST_API_KEY`: the API key for Dream model requests

## Common Use Cases

- Compact agent memory while your laptop is offline
- Keep long-lived project wake-up context concise
- Review every automated memory rewrite through a pull request
- Run the same Dream workflow across multiple projects in one Lagoon repository

## Dependencies for Hippocamp Dream Hosting

### Deployment Dependencies

- A private GitHub repository containing Hippocamp memory
- A fine-grained GitHub token scoped to that repository
- A Manifest or OpenAI-compatible Responses API endpoint and key

## Why Deploy Hippocamp Dream on Railway?

Railway keeps the scheduled compaction job available while your computer is offline. The service is ephemeral, runs on a daily cron, and connects directly to the open-source Hippocamp repository so template deployments can receive upstream updates.

The local Hippocamp MCP remains local-first and does not depend on Railway.
