# game-kit

The shared infrastructure of Wiz-War and Waving Hands, extracted so the next
game starts with all of it in place: the hall, room codes and tables, the
Peanut Gallery (and the host's leave for it to talk), table talk, rematches,
seats that travel between devices by phrase, the keeper's bell, append-only
ledgers replayed through a
deterministic engine, the rules revision, the reports desk, the deploy
script with its determinism gate, nightly rollup and backup, Sentry with
Slack alerts, and the visitors, pulse and reports skills for Claude.

The game itself is one file. `src/lib/game/index.ts` implements `GameSpec`
(see `src/lib/game/spec.ts`); the server, the client store, the hall and
the ops tools never look past it. The template ships with a demo game,
High Card, so everything runs before you have written a line.

## Start a game

    ./new-game.sh <slug> "<Name>" [port] [domain]

That copies `template/` to `~/projects/<slug>`, fills the name, port and
domain in, initialises git, installs dependencies, and prints the steps
that remain: write the game, fill in the hall and rules and guide, create
the droplet and the Sentry project, deploy. `CONVENTIONS.md` is copied to
the new project as `docs/conventions.md`; it is the house style.

Run the demo locally from a new project:

    npm run server      # the game server on its port
    npm run dev -- --host

## What is where

    template/
      src/lib/game/spec.ts        the contract a game implements
      src/lib/game/index.ts       the demo game; replace it
      src/lib/net/                client.ts (calls, held seats, socket), room.svelte.ts (the room store), talk.ts, view.ts
      src/lib/components/         Hall, Lobby, TableTalk, ReportSlip, Board (demo; replace it)
      src/routes/                 the hall, /join/[code], /rules, /guide
      server/src/                 index (routes), rooms (game-agnostic), store (ledger), reports (the desk), ratelimit
      deploy/                     deploy, setup, Caddy, systemd, cron, gate + replay, backup, rollup, pulse, visitors, Slack alert, reports tools
      .claude/skills/             <slug>-visitors, <slug>-pulse, <slug>-reports

Placeholders: `__SLUG__`, `__NAME__`, `__PORT__`, `__DOMAIN__` are filled by
`new-game.sh`; `__IP__`, `__SENTRY_DSN__`, `__SENTRY_PROJECT_ID__`,
`__SENTRY_SLACK_INTEGRATION__` and `__SLACK_CHANNEL_ID__` wait until those
things exist.

## What the kit is, and is not

The model is copy and diverge. A new game starts as a copy of the template
and then goes its own way; the two games that came before it are not
instances of the template and were not rewritten to be. The kit holds the
reference copy of the shared parts and the conventions they follow, so a
third game starts from the best current version of everything.

Drift is meant to be visible, not prevented:

    ./drift.sh ../waving-hands          # how far each shared file has wandered

`drift-map/<slug>.txt` pairs files when a game's layout differs from the
template's. When a game grows something every game should have (the
gallery and the reports desk were both born in one game and ported to the
other), bring it back here, with placeholders, so the next game inherits
it, and read the drift before assuming the kit has it.

The contract is simultaneous rounds: every seat that needs input submits,
then the round resolves; turn-at-a-time games fit as the case where one
seat needs input at a time. A game of single commands with out-of-turn
interruptions, Wiz-War's shape, does not fit and keeps its own server.

## The family

`family.json` lists every game of Kestrel's Hall: slug, name, address,
one-line pitch, player count and origin. Each game ships a copy as
`static/family.json` (the deploy script takes the kit's latest when the kit
is beside the game) and its about panel lists the others under *More games
in Kestrel's Hall*. Add a game here, then deploy the games; nothing
else needs to know.
