# Releasing

## The branching workflow

`main` is always releasable. Everything else is short-lived.

```
feat/whatever ──push──▶ ci runs tests
      │
      └──merge──▶ main ──tag v0.3.0──▶ release builds and publishes to PyPI
```

- **Work on a branch.** Pushing any branch runs `ci.yml`: clippy, the Rust tests,
  the Python bindings built and tested against the freshly built CLI, and mypy
  against the stubs.
- **Merge to `main`** when it is green.
- **Release by tagging.** `Cargo.toml` carries the version and the tag points at
  it. The first job refuses to continue if the two disagree, because PyPI will
  not let a version be reused — not even after it is yanked — so publishing
  0.2.0 under a tag that says v0.3.0 cannot be undone.

```console
$ # on main, working tree clean
$ sed -i 's/^version = .*/version = "0.3.0"/' Cargo.toml
$ cargo build            # refresh Cargo.lock
$ git commit -am 'release 0.3.0'
$ git tag v0.3.0 && git push origin main v0.3.0
```

`__version__` in Python comes from `CARGO_PKG_VERSION`, and maturin reads the
same field, so `Cargo.toml` is the only place a version is written.

## Why pull requests do not trigger CI

`ci.yml` fires on `push` and nothing else. This forge is public and takes pull
requests from strangers; a runner executes whatever the workflow checks out, so a
`pull_request` trigger would run an unread stranger's code on the runner host.
Push-only means the runner only ever executes code that someone with push rights
put there.

The cost is real: a pull request gets no automatic check. Read the diff, push the
branch yourself, and let it run then.

## What has to exist first

### 1. Actions enabled on the forge

Off by default here, deliberately — see `homedocs/services/forgejo-public.md`.
In `app.ini` on moria:

```ini
[actions]
ENABLED = true
```

```console
$ ssh moria 'cd ~/docker-services/forgejo-public && docker compose down && docker compose up -d'
```

Always restart the whole stack. `network_mode: service:forge-wg` means restarting
the forge alone silently strips its networking.

### 2. A runner

The forge has no default route and cannot address the LAN, so it cannot reach a
runner. Runners poll outward, so register one against the **public** URL and let
it come to the forge the same way any other client does:

```console
$ forgejo-runner register --no-interactive \
    --instance https://git.pumpin.online \
    --token <from Settings → Actions → Runners> \
    --name <host> --labels docker
```

It needs Docker and outbound internet — it fetches crates and wheels. It executes
repository code, so put it somewhere you would be willing to lose, not on a host
that matters. moria runs the MCP servers and the forge itself; that is the wrong
box for it.

### 3. A PyPI token

Registered under the **funkpower** account. Make it **project-scoped to
typikon**, not account-wide, and add it as the repository secret `PYPI_TOKEN`.

PyPI's trusted publishing is OIDC and supports GitHub, GitLab, Google Cloud Build
and ActiveState — not Forgejo. So this forge has to hold a long-lived credential,
and scoping it to the one project is the whole of the mitigation available: if
the forge is compromised, what is lost is the ability to publish typikon, not
every package the account owns.

Rotate it at `pypi.org/manage/account/token/` if the forge is ever suspect.

### 4. An npm token

Also under **funkpower**, also scoped to the one package, added as the
repository secret `NPM_TOKEN`. Make it a **granular access token** with write
on `typikon` alone; a classic automation token is account-wide.

It does **not** need "bypass 2FA", and should not have it. npm is withdrawing
direct publish from every token that bypasses 2FA: management operations went
in July 2026, publishing goes in January 2027, after which such a token may
only read private packages and stage a publish. Staging is what this workflow
does, so an ordinary granular token is both sufficient and the one that
survives.

npm has trusted publishing too, and like PyPI's it is OIDC against GitHub
Actions and GitLab, which this forge is neither. So the forge holds a
long-lived credential and the scoping is the whole of the mitigation.

Without the secret the release still succeeds and the npm step warns and
skips, so the first release after the token lapses is a PyPI release and
nothing else. Check the run.

## What gets published

| | |
|---|---|
| `typikon-X.Y.Z.tar.gz` | sdist — builds from source anywhere with a Rust toolchain |
| `…-cp39-abi3-manylinux…x86_64.whl` | |
| `…-cp39-abi3-manylinux…aarch64.whl` | cross-built with `maturin --zig` |

abi3, so one wheel per platform covers every Python from 3.9 up rather than one
per interpreter.

And on npm, one package with two WebAssembly builds in it: `node/` for Node,
which loads the module itself, and `web/` for browsers and bundlers, which
cannot compile WebAssembly synchronously on the main thread and so has to be
awaited. The exports map picks between them. There are no per-platform
artefacts, because WebAssembly has no platforms.

### The npm half needs a hand

The tag does not finish the npm release. The runner **stages** the tarball; it
is not on the registry and `npm install typikon` will not see it until someone
approves it with 2FA:

```console
$ npm stage list
$ npm stage view <stage-id>      # what is in it
$ npm stage approve <stage-id>   # asks for the code
```

Or the **Staged Packages** tab on npmjs.com. Either way a code is asked for,
which is the point: the forge holds a credential that can propose a release and
cannot make one.

`npm stage` wants npm 11.15 or newer on Node 22.14 or newer, on the approving
machine as well as the runner.

**No macOS or Windows wheels.** Forgejo has no hosted runners, so those need a
Mac and a Windows box registered as runners. Until then both fall back to the
sdist, which needs a Rust toolchain on the installing machine — fine for
developers, a wall for everyone else.

## Checking a release without publishing

```console
$ rm -rf dist          # a wheel left in dist/ gets packed into the sdist
$ maturin sdist --out dist && maturin build --release --out dist
$ twine check dist/*
$ python -m venv /tmp/v && /tmp/v/bin/pip install --no-binary :all: dist/*.tar.gz
$ /tmp/v/bin/python -c 'import typikon, datetime; print(typikon.today())'
```

Installing from the sdist with `--no-binary` is the one that catches a missing
file, because it builds the crate from exactly what PyPI would hand someone.

For the npm package:

```console
$ npm/build.sh && node npm/test.mjs
$ npm pack --dry-run npm/dist
```

`npm/test.mjs` resolves `typikon` through a staged `node_modules`, so it tests
the exports map and the built files rather than a lucky relative import. It
compares a year of days field by field against the command line, runs the web
build the way a browser would, and type-checks the published `.d.ts` under
`tsc --strict`. It needs `wasm-bindgen` on PATH at the version `Cargo.lock`
pins, and `tsc` for the last of those.
