eng-pad-server
==============

Read-only sync and web viewer for [eng-pad](https://git.wntrmute.dev/kyle/eng-pad)
engineering notebooks.

The Android app pushes complete notebooks to this server via gRPC. The
server stores them and serves read-only views through a web UI with
SVG rendering. Shareable links allow unauthenticated access to specific
notebooks.

## Features

- **gRPC sync**: receive notebook data from the Android app over TLS
- **Web viewer**: browse notebooks, view pages as SVG, export JPG/PDF
- **Authentication**: password (Argon2id) + FIDO2/U2F security keys
- **Shareable links**: token-based URLs with optional expiry

## Quick Start

```bash
# Build
make eng-pad-server

# Generate example config
cp eng-pad-server.toml.example /srv/eng-pad-server/eng-pad-server.toml
# Edit configuration (TLS certs, database path, etc.)

# Initialize (creates database, prompts for admin user)
./eng-pad-server init

# Run
./eng-pad-server server
```

## Build

```bash
make all          # vet → lint → test → build
make test         # run tests
make lint         # golangci-lint
make proto        # regenerate gRPC code from .proto files
make proto-lint   # buf lint + breaking change detection
```
