# Contributing to Ferrite

Ferrite welcomes focused fixes, protocol compatibility work, tests, and
documentation improvements.

## Development setup

Install the .NET SDK selected by `global.json`, Docker, Python 3, and Node.js
20 or later. Then build and run the non-destructive server-only graph:

```sh
dotnet build Ferrite.sln
./scripts/ferrite-upstream-apps up --android 0 --ios 0
./scripts/ferrite-upstream-apps status
./scripts/ferrite-upstream-apps down
```

`Ferrite.sln` carries the server projects only; the conformance suite that
exercises them lives outside this repository. Verify a change against a runnable
graph and say in the pull request exactly what you ran and what it reported.

Official-client work additionally requires the exact public inputs and
toolchains documented in `interop/upstream-clients/README.md`. Do not commit
upstream checkouts, generated build products, private keys, or run data.

## Changes

Keep a change scoped and add a regression test that proves the externally
visible behavior. For protocol changes, preserve the declared layer and verify
constructor ids, flags, actor perspective, error behavior, state transition,
and peer-visible updates. Avoid assertions that merely prove a request was
accepted when the test name claims stored or delivered state.

Before opening a pull request, build the affected projects and exercise the
changed behavior against a running graph. Explain anything that cannot be run in
the pull request environment. Never put secrets, production credentials, or
Telegram user data in an issue, test, log, or fixture.
