A personal linked-notes vault — markdown, [[wikilinks]], backlinks, tags, graph. |

|

This is an app: the forge runs it. Production follows the default branch; |
| 6 |
every open pull gets a preview at its own address with its own copy of the |
| 7 |
data. Everything the app keeps lives under `FORGE_APP_DATA`, which is what |
| 8 |
makes "production data" and "preview data" two different things. |
| 9 |
|
| 10 |
```sh |
| 11 |
PORT=8080 FORGE_APP_DATA=./data bun run src/server.ts |
| 12 |
bun test |
| 13 |
FORGE_APP_DATA=./data bun run src/tty.ts |
| 14 |
FORGE_APP_DATA=./data bun run src/db.ts --check |
| 15 |
bun run lint:design |
| 16 |
bun run contract:emit |
| 17 |
``` |
| 18 |
|
| 19 |
`app.test` in `forge.json` runs beside `app.run` in every deploy, not before |
| 20 |
it: the preview comes up the moment the app answers, and says `live`, or |
| 21 |
`serving · tests failed` the moment the suite disagrees. |
| 22 |
|
| 23 |
## The shape |
| 24 |
|
| 25 |
One implementation, many doors. `src/actions.ts` is every operation as a |
| 26 |
plain function — `(db, who, input)` in, data or a named failure out — and |
| 27 |
the page, the JSON API, the MCP server and the terminal all call it and |
| 28 |
decide nothing themselves. `AGENTS.md` says how to add to it. |
| 29 |
|
| 30 |
| file | what it is | |
| 31 |
| ---------------------------------- | -------------------------------------------------------------- | |
| 32 |
| `src/actions.ts` | list, add, delete; the audit trail, read | |
| 33 |
| `contract.json` | who may do what: roles, and the least role each verb needs | |
| 34 |
| `src/contract.ts`, `src/can.ts` | the table, read at boot; the forge's evaluator, verbatim | |
| 35 |
| `src/security.ts` | the door: rationing, same origin, the table before the body | |
| 36 |
| `src/audit.ts` | every change and every refused one, as a row | |
| 37 |
| `src/who.ts` | who is asking, from the forge's signed headers | |
| 38 |
| `src/db.ts` | SQLite under `FORGE_APP_DATA`, WAL, forward-only migrations | |
| 39 |
| `src/live.ts` | the in-process bus and `GET /events` | |
| 40 |
| `src/mcp.ts` | the actions as MCP tools at `POST /mcp` | |
| 41 |
| `src/routes.ts` | every path, in one table, each API route described beside it | |
| 42 |
| `src/openapi.ts` | the routes as OpenAPI; committed at `contract/openapi.json` | |
| 43 |
| `src/page.ts` | the HTML, rendered on the server, with its share metadata | |
| 44 |
| `design/tokens.json`, `src/tokens.ts` | the look as data, light and dark; compiled to `/tokens.css` | |
| 45 |
| `src/http.ts` | the floor: headers, body cap, files | |
| 46 |
| `src/server.ts` | boot: open the database, serve | |
| 47 |
| `src/tty.ts` | the terminal, over the same actions | |
| 48 |
| `src/env.ts` | what the forge told this process | |
| 49 |
| `static/app.css`, `static/live.js` | the look in the tokens' words, and the list that stays current | |
| 50 |
|
| 51 |
## What every app stands on |
| 52 |
|
| 53 |
- **The door.** Before a route sees a request, `src/security.ts` rations |
| 54 |
writes (and a stranger's API calls), refuses a write from another site, |
| 55 |
and turns away — before the body is read — anyone the table lets through |
| 56 |
a resource's door for no row at all: 401 for a stranger, 403 for anyone |
| 57 |
else. The action still decides about the real row. |
| 58 |
- **The audit trail.** Every change, and every change refused, is a row: |
| 59 |
who, which resource and verb, which row, when, and whether they were |
| 60 |
let. Admins read it at `GET /api/audit`. A row that cannot be written |
| 61 |
is a log line, never a failed request. |
| 62 |
- **The API, described.** `GET /openapi.json` is `contract/openapi.json`, |
| 63 |
written from the routes by `bun run contract:emit`; each operation names |
| 64 |
its cell of the table (`x-contract`). `bun test` fails while it is stale. |
| 65 |
- **Up, or not.** `GET /healthz` answers `{ ok, version, uptime }`; the |
| 66 |
forge waits on it before it sends anyone to a deploy. |
| 67 |
- **The look.** `design/tokens.json` holds every colour, space and size, |
| 68 |
light and dark; nothing else spells out a colour (`bun run lint:design`), |
| 69 |
and every pair a person reads meets 4.5:1 in both themes. |
| 70 |
- **The open web.** A shared link unfurls (description, Open Graph, a |
| 71 |
card); `/robots.txt` keeps crawlers to the page, and out of previews |
| 72 |
entirely; `/.well-known/security.txt` sends a reporter to the forge |
| 73 |
that runs the app. |
| 74 |
|
| 75 |
## Who you are |
| 76 |
|
| 77 |
The forge says who is asking on every request it proxies, and the app |
| 78 |
verifies the signature (`src/who.ts`); nothing else is trusted. Three tiers: |
| 79 |
|
| 80 |
- **anon** — anyone. Reads. |
| 81 |
- **user** — signed in to the forge and able to see this app. Adds notes, as |
| 82 |
themselves, and removes their own. |
| 83 |
- **admin** — able to write this repository. Removes any note. |
| 84 |
|
| 85 |
"Sign in" is `/__forge/signin?to=<path>` and "Sign out" is |
| 86 |
`/__forge/signout`; the forge answers both on the app's own host. |
| 87 |
|
| 88 |
## Any interface |
| 89 |
|
| 90 |
The same actions, the same rules, at every door. A script is the person |
| 91 |
whose forge grant it carries; a bare script is anonymous. |
| 92 |
|
| 93 |
```sh |
| 94 |
curl https://<app>/api/notes |
| 95 |
curl -X POST https://<app>/api/notes -H 'content-type: application/json' -d '{"body":"hi"}' |
| 96 |
curl -X DELETE https://<app>/api/notes/1 |
| 97 |
``` |
| 98 |
|
| 99 |
As an MCP server, for Claude Code or Claude Desktop — `list_notes`, |
| 100 |
`add_note`, `delete_note`: |
| 101 |
|
| 102 |
```sh |
| 103 |
claude mcp add --transport http __TITLE__ https://<app>/mcp |
| 104 |
``` |
| 105 |
|
| 106 |
```json |
| 107 |
{ |
| 108 |
"mcpServers": { "__TITLE__": { "type": "http", "url": "https://<app>/mcp" } } |
| 109 |
} |
| 110 |
``` |
| 111 |
|
| 112 |
The page stays current over `/events`: a note someone else adds or removes |
| 113 |
appears without a reload. Without JavaScript it is the same page, one |
| 114 |
reload behind. |
| 115 |
|
| 116 |
The terminal opens with the exact command in `FORGE_APP_SSH` when the app |
| 117 |
runs (`ssh -p 2222 <name>@<forge>` — the app is the login name, the forge |
| 118 |
the host; `<name>--<pull>@<forge>` for a preview's). It is `src/tty.ts` on |
| 119 |
a real pty over the same data, as the account at the keyboard. |
| 120 |
|
| 121 |
The forge sets `PORT`, `FORGE_APP_DATA`, `FORGE_APP_ENV` (`production` or |
| 122 |
`preview`), `FORGE_APP_URL`, `FORGE_APP_COMMIT`, `FORGE_APP_SSH` and |
| 123 |
`FORGE_APP_IDENTITY_KEY` when it starts the app. `forge.json` says how. |
