Initial StartOS package for Station Master (v0.5.1)

Built from source via a git submodule pinned to a tag, not a published image — the Dockerfile, main.ts, and manifest should never need to change for an ordinary version bump, only the submodule pin (see UPDATING.md). One volume, one interface serving the browser client + lobby/intent API + SSE stream from a single origin, no dependencies. The server-wide join secret (D14) is seeded on install, exposed via the Get Join Secret action, and blocks start behind a critical task until retrieved — the same first-set/rotation pattern as actual-budget-startos's admin password. Verified on phoenix.local: installs, the critical task correctly blocks an ordinary start, force-starting confirms the daemon binds its port and serves the client, and store.json correctly holds the install-seeded join secret. Not verified: the Get Join Secret action's execution end-to-end — start-cli's `package action run` fails with a client-side deserialization error that reproduces identically against actual-budget's already-shipped equivalent action, so this looks like a start-cli issue rather than a defect here. icon.svg is still the scaffold's hello-world placeholder — no real Station Master icon exists yet to ship in its place.

+
+This is a StartOS service-package repository — it builds a `.s9pk` for StartOS.
+
+Develop it inside a StartOS packaging workspace created by `start-cli s9pk init-workspace`,
+which provides the packaging guide and agent context one level up. If you're reading this in a
+bare clone with no workspace, the full guide is at <https://docs.start9.com/packaging>.
+
+**Start every task at the recipe index** — `../start-technologies/projects/start-sdk/docs/src/recipes.md`
+(or <https://docs.start9.com/packaging/recipes.html>). It maps an intent ("prompt the user to create
+admin credentials", "expose a web UI") to the constructs, the reference pages, and a named production
+package to copy. Find the recipe before you read this package's neighbours: a package you reach by
+grepping may be non-conformant, and the recipe outranks it.
+
+Freshly scaffolded? Work the
+[New Package Checklist](../start-technologies/projects/start-sdk/docs/src/new-package-checklist.md)
+(or <https://docs.start9.com/packaging/new-package-checklist.html>) from top to bottom. It is a
+guide page, not a file in this repo — read it, don't copy it in.
+
+Keep `README.md` (technical reference for an AI support or administering agent) and
+`instructions.md` (end-user docs) in sync with your changes.
+
+**Bugs and feature requests are issues on this repo** (self-hosted Gitea, not GitHub) — file
+them as you find them. Don't record work in the repo instead: no `TODO.md`, no `NOTES.md`, no
+`PLAN.md`. What you verified, tried, and decided belongs in the commit message and the PR body.

+## This repo
+
+- **Station Master is a git submodule (`station-master/`), not vendored source.** It tracks
+  [Jesse's own game repo](https://draco.local:53871/Jesse.Markowitz/station-master), self-hosted,
+  pinned to a tag. See `UPDATING.md` for how the pin is bumped — the `Dockerfile`, `main.ts`, and
+  the manifest should never need to change for an ordinary version bump.
+- **Built from source, not a published image.** The `Dockerfile` is entirely this repo's own:
+  a `node:*-slim` builder stage runs the submodule's `npm run build:web` to produce the static
+  client, then a runtime stage copies only `package.json`, `src/`, and the built `dist/` — no
+  `node_modules`, since `src/server/index.ts` has zero runtime dependencies (see the submodule's
+  own `TODO.md` for why) and Node's native TypeScript type-stripping means it needs no compile
+  step either.
+- **The join secret (D14 in the game's `docs/architecture/multiplayer.md`) is this package's one
+  piece of state beyond the game data itself.** `startos/fileModels/store.json.ts` holds it,
+  seeded on install (`startos/init/generateJoinSecret.ts`) since the server refuses to start
+  without one, and rotated by the **Get Join Secret** action
+  (`startos/actions/getJoinSecret.ts`) — the same action handles first retrieval and rotation, per
+  `recipe-admin-credentials.md`.
+- **One volume, one interface, no dependencies.** Everything the server persists —
+  `store.json` and every game's own save data — lives on the `data` volume; the single `ui`
+  interface carries the browser client, the lobby/intent HTTP API, and the SSE game stream from
+  one port, which is what keeps players reachable from different addresses in the same game
+  (`docs/architecture/deployment.md` §3 in the game repo).

+Station Master is a railroad operations board game with an authoritative multiplayer server;
+solitaire needs no server and is not what this package is for. This package runs that server —
+the browser client, the lobby, and the intent/SSE API — as a single StartOS service.

+
+## Image and Container Runtime
+
+Built from source with a custom `Dockerfile` — there is no published Station Master image.
+
+| What to Document | Value |
+| --- | --- |
+| Image source | Custom multi-stage `Dockerfile`: `node:*-slim` builder runs `npm run build:web` to produce the static client, then a second `node:*-slim` stage copies only `package.json`, `src/`, and the built `dist/` — no `node_modules` in the runtime stage, since the server has zero runtime dependencies |
+| Architectures | x86_64, aarch64 |
+| Entrypoint | `node src/server/index.ts` — runs straight from TypeScript source; no compile step, see Limitations |
+
+One subcontainer: `station-master-sub`, running the single daemon `server`.
+
+## Volume and Data Layout
+
+One volume, `data`, mounted at `/data` (`DATA_DIR`).
+
+| What to Document | Value |
+| --- | --- |
+| Volume names | `data` |
+| Mount points | `/data` |
+| StartOS files | `store.json` — holds the join secret (see File Models) |
+| Database | None — flat files. Each game is `games/<gameId>/game.json` (`{ engineVersion, seed, config, playerNames, history, status, createdAt }`) plus `turn-timings.json`, an `index.json` naming every game, and lobby state for games not yet started |
+
+## File Models
+
+One StartOS-managed file, `store.json`, on the `data` volume.
+
+- **`store.json`** — JSON, holds `joinSecret` (a string). Seeded on install with a random
+  24-character value (`init/generateJoinSecret.ts`) — the daemon will not start without one, so
+  it is never left unset. Rewritten only by the **Get Join Secret** action, which generates a new
+  value on every run; the value is otherwise never touched, so a hand edit to it survives until
+  the action is next run. `main.ts` reads it reactively, so a rewrite restarts the daemon with the
+  new value automatically.
+
+Everything else under `/data` — `games/`, `index.json`, lobby and session state — is the
+application's own persistence, written directly by the server process, not by a StartOS file
+model.
+
+## Dependencies
+
+None.
+
+## Network Access and Interfaces
+
+One interface, `ui`, on the single port the daemon listens on. It serves the browser client, the
+lobby and intent HTTP API, and the per-seat SSE game stream — all from the same origin, which is
+what lets a player reach the server from a LAN address and another player reach it from a
+different one in the same game.
+
+## Installation and First-Run Flow
+
+No setup wizard. On install, a join secret is generated and stored immediately (see File Models),
+and a critical task is raised pointing at **Get Join Secret** — the service starts and is usable
+the moment the daemon is healthy, but a player cannot create or join a game until the join secret
+has been retrieved and shared with them.
+
+## Actions
+
+- **Get Join Secret** (`get-join-secret`) — run this any time you want to read the current join
+  secret, or to invalidate it and issue a new one. Every run **generates a fresh secret,
+  overwrites the stored one, and restarts the daemon** with it — there is no read-only mode.
+  Rotating does not disconnect players already seated in a running game (D14's join secret gates
+  the lobby door, not an in-progress session); it only invalidates the old value for anyone who
+  has not yet joined or created a game. Completes in a few seconds, safe to repeat.
+
+## Tasks
+
+- **Get the join secret to share with players** — raised on install, severity `critical`. Points
+  at the **Get Join Secret** action. Clears the moment that action is run for the first time; it
+  does not return afterward (running it again to rotate does not re-raise it).
+
+## Health Checks
+
+- **Multiplayer Server** — `checkPortListening` against the daemon's port. "Not ready" means the
+  process has not yet bound its port; on a normal start this clears within a second or two; on a
+  cold container start it briefly reflects the daemon starting up.
+
+## Backups and Restore
+
+Strategy: the entire `data` volume is backed up wholesale (`ofVolumes`) — every file copied
+exactly as it sits on disk, nothing dumped and replayed.
+
+That includes every game's full intent history, so a restore can resume any in-progress game
+exactly where it left off, and the join secret in `store.json`, so previously shared join links
+keep working after a restore. Nothing needs to be rebuilt or re-entered after a restore; the
+server resumes every saved game on boot the same way it does after an ordinary restart.
+
+## Limitations and Differences
+
+1. **No compile step.** The image runs the server directly from TypeScript source using Node's
+   native type stripping, rather than building a `dist/` for the server the way the browser
+   client is built. This is upstream's own deployment shape (`docs/architecture/deployment.md` in
+   the game repo), not something this package changed.
+2. **The join secret has no per-player identity.** It is a single server-wide value (D14) that
+   gates who may create or join a game — it is not a username or password, and StartOS has no
+   visibility into who a player is once they've joined.
+3. **No accounts, and one game at a time per person is expected but not enforced** — a deliberate
+   upstream design decision (`docs/architecture/multiplayer.md` §11 D13), not a StartOS-specific
+   limitation.

+# Updating the upstream version
+
+Station Master is built from a git submodule at `station-master/` (tracking
+[`Jesse.Markowitz/station-master`](https://draco.local:53871/Jesse.Markowitz/station-master), a
+self-hosted Gitea repo — this is Jesse's own game, not a third-party upstream, but it is packaged
+the same way: `Dockerfile` builds whatever commit the submodule points at, with no pinned
+`dockerTag` in the manifest. The submodule pin **is** the version.
+
+Station Master tags its releases (`v0.5.1`, …) at the commit that bumped `package.json`. Nothing
+else about this package should need to change for a bump — not the `Dockerfile`, not `main.ts`,
+not the manifest — only the submodule pin and this package's own version (below).
+
+## Determining the upstream version
+
+```bash
+cd station-master && git fetch --tags && git tag -l --sort=-v:refname | head -5
+```
+
+The current pin is the submodule's checked-out commit:
+
+```bash
+git submodule status station-master
+```
+
+## Applying the bump
+
+```bash
+cd station-master && git fetch --tags && git checkout v<new version>
+cd .. && git add station-master
+```
+
+Then bump this package's own version in `startos/versions/current.ts` (see
+[Versions](../start-technologies/projects/start-sdk/docs/src/versions.md)) with release notes
+naming the Station Master version now bundled — e.g. "Bundles Station Master v0.5.2." — and
+rebuild (`make`).
+
+If the jump carries a multiplayer protocol or persistence-format change (check the game repo's
+`CHANGELOG.md` and `docs/architecture/multiplayer.md`), read it before bumping: a running
+server's saved games are stamped with `engineVersion` and refuse to resume under a mismatched
+one (`src/server/index.ts` in the game repo) — nothing in this package works around that, so an
+in-progress game must finish (or be accepted as lost) before an incompatible bump.

+# Station Master
+
+## Documentation
+
+- [Rules and design docs](https://draco.local:53871/Jesse.Markowitz/station-master/src/branch/main/docs)
+  — the rulebook implications, the multiplayer design, and the game's architecture.
+
+## What you get on StartOS
+
+This service runs the multiplayer server: a lobby, and a table for 2 to 4 players to play a
+competitive or cooperative game together from their own browsers. Everything a player needs — the
+game itself, the lobby, and the connection back to this server — is served from the single web
+interface below; there is nothing else to install or configure on a player's side.
+
+## Getting set up
+
+1. Open this service's **Multiplayer Table** interface.
+2. Run the **Get Join Secret** action from this service's Actions menu, and copy the value it
+   returns.
+3. Share that secret, and the address you opened the interface at, with everyone you want to
+   play with. Anyone holding the secret can create a new game or join one that hasn't started yet.
+4. In the browser, click **Multiplayer**, then **Create Game** (or **Join Game** with a game code
+   someone else created), and enter the join secret when asked.
+
+## Using Station Master
+
+### Multiplayer Table
+
+Create or join a game, seat players (including filling empty seats with a bot), and start. Once a
+game is underway, this same interface is where every player plays their turns and watches the
+table — there is nothing else to open.
+
+### Get Join Secret
+
+Run this whenever you need the current join secret again, or want to shut out anyone still
+holding an old one. Every run replaces the secret and immediately puts the new one into effect —
+players already seated in a game are unaffected, but the old secret stops working for creating or
+joining games from that point on.
