This is an app: the forge runs it. Production follows the default branch;

every open pull gets a preview at its own address with its own copy of the

data. Everything the app keeps lives under `FORGE_APP_DATA`, which is what

makes "production data" and "preview data" two different things.

```sh

PORT=8080 FORGE_APP_DATA=./data bun run src/server.ts   # run it here

bun test                                                # what `forge.json`'s app.test runs on every push

FORGE_APP_DATA=./data bun run src/tty.ts                # the terminal

FORGE_APP_DATA=./data bun run src/db.ts --check         # schema version, integrity

bun run lint:design                                     # no colour but the tokens'

bun run contract:emit                                   # rewrite contract/openapi.json from the routes

```

`app.test` in `forge.json` runs beside `app.run` in every deploy, not before

it: the preview comes up the moment the app answers, and says `live`, or

`serving · tests failed` the moment the suite disagrees.

## The shape

One implementation, many doors. `src/actions.ts` is every operation as a

plain function — `(db, who, input)` in, data or a named failure out — and

the page, the JSON API, the MCP server and the terminal all call it and

decide nothing themselves. `AGENTS.md` says how to add to it.

| file                               | what it is                                                     |

| ---------------------------------- | -------------------------------------------------------------- |

| `contract.json`                    | who may do what: roles, and the least role each verb needs     |

| `src/contract.ts`, `src/can.ts`    | the table, read at boot; the forge's evaluator, verbatim       |

| `src/security.ts`                  | the door: rationing, same origin, the table before the body    |

| `src/audit.ts`                     | every change and every refused one, as a row                   |

| `src/who.ts`                       | who is asking, from the forge's signed headers                 |

| `src/db.ts`                        | SQLite under `FORGE_APP_DATA`, WAL, forward-only migrations    |

| `src/live.ts`                      | the in-process bus and `GET /events`                           |

| `src/mcp.ts`                       | the actions as MCP tools at `POST /mcp`                        |

| `src/routes.ts`                    | every path, in one table, each API route described beside it   |

| `src/openapi.ts`                   | the routes as OpenAPI; committed at `contract/openapi.json`    |

| `src/page.ts`                      | the HTML, rendered on the server, with its share metadata      |

| `design/tokens.json`, `src/tokens.ts` | the look as data, light and dark; compiled to `/tokens.css` |

| `src/http.ts`                      | the floor: headers, body cap, files                            |

| `src/server.ts`                    | boot: open the database, serve                                 |

| `src/tty.ts`                       | the terminal, over the same actions                            |

| `src/env.ts`                       | what the forge told this process                               |

| `static/app.css`, `static/live.js` | the look in the tokens' words, and the list that stays current |

## What every app stands on

- **The door.** Before a route sees a request, `src/security.ts` rations

  writes (and a stranger's API calls), refuses a write from another site,

  and turns away — before the body is read — anyone the table lets through

  a resource's door for no row at all: 401 for a stranger, 403 for anyone

  else. The action still decides about the real row.

- **The audit trail.** Every change, and every change refused, is a row:

  who, which resource and verb, which row, when, and whether they were

  let. Admins read it at `GET /api/audit`. A row that cannot be written

  is a log line, never a failed request.

- **The API, described.** `GET /openapi.json` is `contract/openapi.json`,

  written from the routes by `bun run contract:emit`; each operation names

  its cell of the table (`x-contract`). `bun test` fails while it is stale.

- **Up, or not.** `GET /healthz` answers `{ ok, version, uptime }`; the

  forge waits on it before it sends anyone to a deploy.

- **The look.** `design/tokens.json` holds every colour, space and size,

  light and dark; nothing else spells out a colour (`bun run lint:design`),

  and every pair a person reads meets 4.5:1 in both themes.

- **The open web.** A shared link unfurls (description, Open Graph, a

  card); `/robots.txt` keeps crawlers to the page, and out of previews

  entirely; `/.well-known/security.txt` sends a reporter to the forge

  that runs the app.

## Who you are

The forge says who is asking on every request it proxies, and the app

verifies the signature (`src/who.ts`); nothing else is trusted. Three tiers:

- **anon** — anyone. Reads.

- **user** — signed in to the forge and able to see this app. Adds notes, as

  themselves, and removes their own.

- **admin** — able to write this repository. Removes any note.

"Sign in" is `/__forge/signin?to=<path>` and "Sign out" is

`/__forge/signout`; the forge answers both on the app's own host, and

`/__forge/report` too: it sends anyone, with no account, to report a

problem on this app's repository, if that repository is public.

## Any interface

The same actions, the same rules, at every door. A script is the person

whose forge grant it carries; a bare script is anonymous.

```sh

curl https://<app>/api/notes

curl -X POST https://<app>/api/notes -H 'content-type: application/json' -d '{"body":"hi"}'

curl -X DELETE https://<app>/api/notes/1

```

As an MCP server, for Claude Code or Claude Desktop — `list_notes`,

`add_note`, `delete_note`:

```sh

claude mcp add --transport http __TITLE__ https://<app>/mcp

```

```json

{

  "mcpServers": { "__TITLE__": { "type": "http", "url": "https://<app>/mcp" } }

}

```

The page stays current over `/events`: a note someone else adds or removes

appears without a reload. Without JavaScript it is the same page, one

reload behind.

The terminal opens with the exact command in `FORGE_APP_SSH` when the app

runs (`ssh -p 2222 <name>@<forge>` — the app is the login name, the forge

the host; `<name>--<pull>@<forge>` for a preview's). It is `src/tty.ts` on

a real pty over the same data, as the account at the keyboard.

The forge sets `PORT`, `FORGE_APP_DATA`, `FORGE_APP_ENV` (`production` or

`preview`), `FORGE_APP_URL`, `FORGE_APP_COMMIT`, `FORGE_APP_SSH` and

`FORGE_APP_IDENTITY_KEY` when it starts the app. `forge.json` says how.
