# Progress

## Phase 1 — Repository Setup

- [x] **Step 1.1 — Create the monorepo.** pnpm workspace with `apps/web`, `apps/server`, `packages/sim`, `packages/schema`, `packages/content` (all `@deadhead/*`), strict `tsconfig.base.json` extended by each package. `pnpm install` + `pnpm typecheck` pass. Repo moved to `C:\Projects\Deadhead Space Freight Tycoon` (G: is exFAT, no symlinks).
- [x] **Step 1.2 — Linting and formatting.** ESLint 10 + typescript-eslint + Prettier at the root (`pnpm lint`, `pnpm format`). Purity rule bans `Math.random`, `Date.now` and argument-less `new Date()` in `packages/sim` and `packages/content`; verified it fails on a planted `Math.random()`.
- [x] **Step 1.3 — Test runner.** Vitest 5 with one project per workspace package (`pnpm test`). Trivial smoke test in `packages/sim/test/smoke.test.ts`; 1 passing.
- [x] **Step 1.4 — Continuous integration.** Repo pushed to Gitea; `.gitea/workflows/ci.yml` runs install, typecheck, lint and test on every push (runner `homelab-runner`). Run #1 failed because Prettier scanned the runner's in-workspace `.pnpm-store/`; ignored it, and run #2 is green.
- [x] **Step 1.5 — Local Postgres.** `docker compose up -d` starts Postgres 18 with `deadhead` (dev) and `deadhead_test` databases; connected to both with psql. `.env.example` lists the server's env vars.

## Phase 2 — Content Package

- [x] **Step 2.1 — Content schemas.** Zod 4 schemas in `packages/content/src/schemas.ts` for Location, ShipModel, CargoType, Skill and GameConfig, with inferred types. Tests check that each schema accepts a valid example and rejects it with any one field missing.
- [x] **Step 2.2 — The five locations.** `src/data/locations.ts`: Earth, Moon, Mars, Ceres Station, Jupiter Cloud Platform. Earth and Moon start discovered; Earth has the highest launch multiplier.
- [x] **Step 2.3 — The three ship models.** `src/data/ships.ts`: Courier, Freighter, Bulk Hauler, all atmospheric. Speed, capacity and price orderings tested; range rules are checked in Step 3.7.
- [x] **Step 2.4 — Cargo types and skills.** `src/data/cargo.ts`: Standard, Heavy, High-Value, Dangerous; skills Long Haul, Heavy Cargo, Expensive Cargo, Dangerous Cargo (max level 5). The location test now checks cargo ids against the real data.
- [x] **Step 2.5 — Default game config.** `src/data/config.ts`. Courier + Earth bay ≈ 21 tutorial runs with the placeholder average payout. Money values rescaled ×10 so tutorial runs pay meaningful amounts; epoch moved from `.env.example` into GameConfig.
- [x] **Step 2.6 — Single content bundle.** `content` in `src/bundle.ts` holds all data plus `location`, `shipModel`, `cargoType` and `skill` lookups that return `undefined` for unknown ids.

## Phase 3 — Simulation Package

- [x] **Step 3.1 — Game clock conversion.** `src/clock.ts`: `realToGame` / `gameToReal` using the config epoch and compression; times are Unix-ms numbers.
- [x] **Step 3.2 — Seeded RNG.** `src/rng.ts`: `createRng(seed)` (mulberry32) with `next`, `int`, `pick`; `deriveSeed(parent, label)` for child seeds.
- [x] **Step 3.3 — Location positions.** `src/positions.ts`: heliocentric ecliptic positions (million km) from `astronomy-engine` for Earth, Mars and Jupiter; Moon = Earth + fixed offset; Ceres on a circular orbit.
- [x] **Step 3.4 — Route distance.** `src/distance.ts`: `routeDistance(from, to, gameTime)`, straight-line million km.
- [x] **Step 3.5 — Travel time.** `src/travel.ts`: `travelTimeGameHours(ship, distance)` = cruise time + overhead.
- [x] **Step 3.6 — Fuel cost.** `src/fuel.ts`: `fuelCost(ship, origin, distance)` = distance × cost per million km × origin launch multiplier.
- [x] **Step 3.7 — Range and landing eligibility.** `src/eligibility.ts`: `checkRoute` returns `ok` or `cannot-land` / `out-of-range`; `canLandAt` ranks vacuum < atmospheric < hardened. Step 2.3 ranges confirmed against sampled real distances.
- [x] **Step 3.8 — Contract model and payout.** `src/contract.ts`: `Contract` interface and `contractPayout` (base × multiplier^tier × mass × distance × first-contact multiplier, rounded).
- [x] **Step 3.9 — Contract board generation.** `src/board.ts`: `generateContractBoard` (seeded per world, bay and period), plus `boardPeriodIndex`, `requiredLongHaulLevel` and the `SimContent` input type. First contact ≈10% over 1,000 boards.
- [x] **Step 3.10 — Tutorial contract board.** `src/tutorial.ts`: `generateTutorialBoard` (Earth↔Moon from the loaner's location, Standard cargo capped at Courier capacity, payout × tutorial share); `loanerModel`. `SimContent` gained `shipModels`.
- [x] **Step 3.11 — Pilot eligibility.** `src/pilot.ts`: `checkPilotEligibility(skills, contract)` returns `ok` or `cargo-skill-too-low` / `long-haul-too-low`.
- [x] **Step 3.12 — Dispatch validation.** `src/dispatch.ts`: `ShipState`, `PilotState`, `validateDispatch` (first failing reason, plan order), `tripFuelCost` (rounded). One test per failure reason plus tutorial cases.
- [x] **Step 3.13 — Dispatch record creation.** `createDispatchRecord` in `src/dispatch.ts`: `DispatchRecord` with arrival from travel time, fuel cost, departure distance, a `tutorial` flag and a per-dispatch seed.
- [x] **Step 3.14 — Reposition dispatch.** `validateReposition` and `createRepositionRecord` in `src/dispatch.ts`: empty flight to a player bay, range/landing/fuel only, zero payout. Zero XP is covered by resolution (Step 3.17).
- [x] **Step 3.15 — In-flight position and progress.** `src/flight.ts`: `dispatchProgress` (clamped 0–1) and `dispatchPosition` (straight line from origin at departure to destination at arrival).
- [x] **Step 3.16 — XP and leveling.** `src/xp.ts`: `deliveryXp`, `pilotLevel`, `skillPointsAvailable`.
- [x] **Step 3.17 — Dispatch resolution.** `src/resolution.ts`: `resolveDispatch` returns `in-flight` or a `Resolution` (credits after pilot pay, XP, new ship location, discovery).
- [x] **Step 3.18 — Public API and coverage.** `src/index.ts` exports an explicit list (content lookups and contract building stay internal). `pnpm coverage` (V8, `packages/sim/src`, 90% line threshold) reports 100% lines; CI now runs `pnpm coverage` instead of `pnpm test`.

## Phase 4 — Shared Schema Package

- [x] **Step 4.1 — API data shapes.** `packages/schema/src`: entity schemas (`entities.ts`), error format and codes (`errors.ts`), request/response bodies (`requests.ts`). Error codes include every sim validation reason; sim now exports `DISPATCH_FAILURES` / `REPOSITION_FAILURES`. `architecture.md` started with the API data model.
- [x] **Step 4.2 — API route catalog.** `packages/schema/src/routes.ts`: 13 typed endpoints under `/api` with request/response schemas and an `auth` flag, plus `RouteRequest` / `RouteResponse` helper types. Route table added to `architecture.md`.

## Phase 5 — Server Foundation

- [x] **Step 5.1 — Fastify skeleton.** `apps/server`: Zod-validated env config (`src/config.ts`), `buildApp` with pino JSON logging and `GET /api/health` (`src/app.ts`), entry point `src/main.ts` (loads repo-root `.env` if present). `pnpm --filter @deadhead/server dev|start` run it with tsx. Integration test starts the app on an ephemeral port and calls health over HTTP.
- [x] **Step 5.2 — Server time endpoint.** `GET /api/time` returns `{ realTime, gameTime }` from an injectable `Clock` (`src/clock.ts`, passed via `buildApp(config, { clock })`).
- [x] **Step 5.3 — Database schema and migrations.** Drizzle schema (`apps/server/src/db/schema.ts`, copied into `architecture.md`), first migration `drizzle/0000_init.sql`, `db:generate` / `db:migrate` scripts. Migration test runs against an emptied test database twice. CI now has a Postgres 18 service; server tests run one file at a time.
- [x] **Step 5.4 — Test database harness.** `apps/server/test/db.ts`: `useTestDatabase()` (migrate once, truncate all tables before each test) and `seedPlayer(db, "tutorial" | "owner")`. New-player creation lives in `src/game/new-player.ts` (`createPlayer`), shared with guest sign-up.
- [x] **Step 5.5 — Guest accounts.** Better Auth with the anonymous plugin (`src/auth.ts`, tables in `src/db/auth-schema.ts`, migration `0001_auth`). `POST /api/guest` creates a guest session and a tutorial player; `GET /api/state` returns player state for the session or `401 unauthorized`. Error handler sends the documented error format.
- [x] **Step 5.6 — Request validation from the route catalog.** `registerRoute` (`src/http/route.ts`) validates merged params/query/body before auth, checks sessions for `auth` routes, and checks responses outside production. Malformed JSON and unexpected fields return `400 validation-error`.

## Phase 6 — Server Game Logic

- [x] **Step 6.1 — Lazy resolution on read.** `resolveArrivedDispatches` (`src/game/resolve.ts`) resolves arrived dispatches in arrival order inside `withPlayerLock` (`src/game/lock.ts`, a transaction holding the company row lock); a conditional status update makes each resolve exactly once. `GET /api/state` runs it before reading. Routes moved to `src/routes/`.
- [x] **Step 6.2 — Get full player state.** Endpoint from Step 5.5 plus lazy resolution; test covers a player with one ship in flight and one idle (crewed by a hired pilot), checking ships, pilots (XP, level, skills, points, assignment, status, location), bays, dispatches, summaries and schema validity.
- [x] **Step 6.3 — Tutorial board endpoint.** `GET /api/tutorial/board` (`src/routes/boards.ts`, `src/game/boards.ts`): stored per (period, loaner location) on first request, accepted contracts hidden, `409 not-in-tutorial` after the tutorial. Every game route now runs through `withPlayer` (lock + lazy resolution).
- [x] **Step 6.4 — Tutorial dispatch.** `POST /api/dispatches` with `kind: "tutorial"` (`src/game/dispatch.ts`): avatar + loaner, sim validation, no fuel, one run at a time; contract marked accepted. Arrival pays the stored tutorial payout and moves loaner and avatar.
- [x] **Step 6.5 — Buy a ship.** `POST /api/ships` (`src/game/fleet.ts`, `src/routes/fleet.ts`): deducts the price, adds an idle uncrewed ship at Earth named from the world seed (`src/game/names.ts`); `409 insufficient-funds` changes nothing.
- [x] **Step 6.6 — Lease a bay.** `POST /api/bays` (`leaseBay` in `src/game/fleet.ts`): one-time lease price at a discovered location; `409 location-undiscovered`, `409 bay-already-leased`, `409 insufficient-funds`, `404 not-found`.
- [x] **Step 6.7 — End tutorial.** `maybeEndTutorial` (`src/game/tutorial.ts`) runs after each resolution pass and after every game action: with a ship, an Earth bay and no tutorial run in flight, tutorial mode turns off, the loaner is removed, and the avatar becomes an idle, unassigned pilot at Earth.
- [x] **Step 6.8 — Hire and assign pilots.** `POST /api/pilots`, `/api/pilots/:pilotId/assign`, `/api/pilots/:pilotId/unassign` (`src/game/pilots.ts`): hire at a bay for the fee with a seeded name; assign to an idle, uncrewed ship at the same location; unassign only at a bay. New error code `avatar-in-tutorial`.
- [x] **Step 6.9 — Bay contract board endpoint.** `GET /api/bays/:locationId/board` (`bayBoard` in `src/game/boards.ts`): generated from the discovered set on first request in a period and stored; accepted contracts hidden; `409 no-bay-at-location` without a bay. The expired-old-board dispatch check is tested in Step 6.10.
- [x] **Step 6.10 — Contract dispatch.** `POST /api/dispatches` with `kind: "contract"` (`dispatchContract`): sim validation, fuel deducted, contract accepted, ship and pilot in flight. One integration test per sim reason (`cannot-land` via a test-only vacuum ship in mocked content), each checking nothing changed; also covers the expired-old-board case from Step 6.9.
- [x] **Step 6.11 — Reposition dispatch.** `POST /api/dispatches` with `kind: "reposition"` (`dispatchReposition`): sim reposition validation against the player's bays, fuel only, no payout or XP; ship and pilot arrive at the destination.
- [x] **Step 6.12 — Spend skill points.** `POST /api/pilots/:pilotId/skills` (`spendSkillPoint`): +1 skill level, +1 point spent; `409 no-skill-points`, `409 skill-maxed`, `404 unknown-skill`.
- [x] **Step 6.13 — Acknowledge summaries.** `POST /api/summaries/acknowledge` (`src/game/summaries.ts`) sets `acknowledged_at` on the player's resolved, unacknowledged dispatches among the given ids and returns how many; resolved effects are untouched.
- [x] **Step 6.14 — Concurrency and money safety.** Every authenticated endpoint runs in `withPlayer` (transaction + company row lock). Race tests: two and eight simultaneous purchases, a contract dispatched twice at once, a bay leased twice at once; three of them fail when the lock is removed.

## Phase 7 — Background Workers

- [x] **Step 7.1 — pg-boss setup.** `src/jobs/queue.ts`: `JobQueue` interface, pg-boss implementation (queues always created; workers and cron schedules only when `WORKERS_ENABLED=true`), and a recording fake for tests. The app starts the queue on ready and stops it on close. Test runs a no-op job to completion with real pg-boss.
- [x] **Step 7.2 — Arrival resolution job.** Every dispatch (contract, tutorial, reposition) schedules a `resolve-arrivals` job at its arrival (`src/jobs/definitions.ts`), which runs the same locked resolution as lazy reads and is a no-op if already resolved. Clock is now base clock + offset; test-only `POST /api/test/clock-offset` (not registered in production) moves it.
- [x] **Step 7.3 — Expired contract cleanup.** Hourly `cleanup-expired-contracts` job (`src/jobs/cleanup.ts`) deletes stored boards and accepted-contract records more than 24 board periods old; current ones stay.

## Phase 8 — Client Foundation

- [x] **Step 8.1 — Vite + React app.** `apps/web`: Vite 8, React 19, Tailwind 4, React Router 8. Layout (header with credits and game clock, main area, fixed six-tab bottom navigation) and placeholder screens for HQ, Contracts, Fleet, Pilots, Market, Locations. Component tests in jsdom. Dev server proxies `/api` to `127.0.0.1:3000`. Manual 375px check: passed on the user's iPhone.
- [x] **Step 8.2 — Typed API client.** `apps/web/src/api/client.ts`: `createApiClient().call(name, input)` built from the route catalog: path params filled, GET query / POST JSON body, `credentials: "include"`, responses validated (`ApiValidationError`), server errors raised as `ApiError` with code and message.
- [x] **Step 8.3 — Server-synced clock.** `apps/web/src/clock`: Zustand `useClock` store, `syncClock(api)` (offset from server time, half round trip), `serverNow()`, `startClockTicker()` (1 s), and a `GameClock` header component showing in-game time.
- [x] **Step 8.4 — Guest onboarding.** No session (state request returns 401) shows `StartScreen`; "Start your company" calls `createGuest`, caches the returned state and opens HQ. The session is Better Auth's persistent cookie. TanStack Query and an `ApiProvider` context added; header shows live credits. Verified end to end through the Vite proxy.
- [x] **Step 8.5 — Player state store.** `usePlayerState` (TanStack Query) refetches on window focus and, via `useRefetchOnArrival`, once per dispatch when the server clock passes its arrival time.

## Phase 9 — Client Screens

- [x] **Step 9.1 — HQ screen.** `src/screens/HQ.tsx`: credits, game date, idle/in-flight counts, next arrival with live countdown, tutorial goal progress (cheapest ship + Earth bay). Shared helpers: `src/format.ts`, `Countdown`, `useLoadedPlayer` / `useGameAction` (`src/state/actions.ts`).
- [x] **Step 9.2 — "While you were away" summary.** `src/components/AwaySummary.tsx`: dialog over every screen listing each unacknowledged delivery (ship or "Company loaner", route, credits, XP, discovery); "Got it" hides it at once and calls `acknowledgeSummaries`.
- [x] **Step 9.3 — Tutorial contract board.** Contracts screen shows the tutorial board during the tutorial (`src/screens/TutorialBoard.tsx`): route, cargo, mass, payout, sim-predicted trip time (`src/game.ts`), and "Fly it" (disabled while a run is in flight; server errors shown).
- [x] **Step 9.4 — Bay contract boards.** After the tutorial the Contracts screen shows `BayBoards`: a bay selector and, per contract, route, cargo (and tier), mass, current distance, payout, required skills, live expiry countdown and a first-contact badge.
- [x] **Step 9.5 — Dispatch flow.** `src/screens/DispatchSheet.tsx`: each idle ship at the pickup with its pilot, checked with sim `validateDispatch`; eligible pairs show trip time, fuel, net profit and game/real ETA; ineligible pairs are disabled with a short reason; Confirm sends the dispatch and shows server errors.
- [x] **Step 9.6 — Fleet screen.** `src/screens/Fleet.tsx`: ships with model, location or route, pilot; in-flight progress bar (sim `dispatchProgress`) and countdown; "Reposition" for idle crewed ships at a bay opens a picker of the player's other bays.
- [x] **Step 9.7 — Pilots screen.** `src/screens/Pilots.tsx`: level, XP progress to next level, skills, points, assignment and status per pilot; hire at a chosen bay (cost shown, disabled when unaffordable); assign to idle uncrewed ships at the pilot's location; "+" to spend a skill point.
- [x] **Step 9.8 — Market screen.** `src/screens/Market.tsx`: ship models with speed, capacity, range, landing class and price; Buy disabled when unaffordable; a bought ship shows a confirmation and appears in Fleet after the state refresh.
- [x] **Step 9.9 — Locations screen.** `src/screens/Locations.tsx`: discovered locations show type, landing need, current distance from Earth, produces/demands and "Lease bay (price)" or "Bay owned"; undiscovered ones show only the name and "Undiscovered — deliver here to unlock."
- [x] **Step 9.10 — Empty and error states.** First-load failure shows "Could not reach the server" with Retry; a failed refresh keeps the last state with an "Offline — showing last update" banner and Retry; boards have their own Retry. Empty states on HQ, Fleet, Contracts (no bays, empty bay/tutorial board) and Pilots. Tests cover every screen.

## Phase 10 — Simple System Map

- [x] **Step 10.1 — PixiJS map component.** Map tab (`/map`, lazy-loaded) with a PixiJS v8 canvas (`src/map/MapCanvas.tsx`): Sun, orbit rings, five locations (dimmed if undiscovered, ring if a bay), drag to pan, pinch or wheel to zoom, "Reset view". Square-root radial scale and screen projection in `src/map/projection.ts`, camera in `src/map/camera.ts`. Tests: scale monotonic, locations fit a 375 px map for 12 years, zoom keeps the anchor fixed. Manual phone check pending.
- [x] **Step 10.2 — Ships on the map.** `flightMarker` / `buildScene` (`src/map/scene.ts`): each in-flight dispatch draws a route line (origin at departure → destination at arrival) with a marker placed by sim progress every frame; idle ships (tutorial loaner included) show as a count badge at their location. Test: marker at 50% lies halfway along the route line on screen. Manual smoothness check pending.
- [x] **Step 10.3 — Map interactions.** Taps (single pointer, under 8 px of movement) are hit-tested (`src/map/hitTest.ts`, 22 px reach, ships win ties). A location panel shows details (or "Undiscovered") and, with a bay, a link to `/contracts?bay=…` which preselects that board; a ship panel shows route, pilot and ETA. Component tests tap through a canvas test double that uses the real scene.

## Phase 10A — Faster Start (CR-001)

Spec: `memory-bank/change-requests/CR-001-faster-start.md`. Decisions recorded as plan §0.5.29–0.5.34.

- [x] **Step 10A.1 — Content: new config and loaner ship.** `purchasable` on ShipModel; "Company Courier" (not purchasable, 6M km/h, 0.3 h overhead, 20 t); config: `tutorialLoanerShipModelId`, `tutorialRunsBeforeDeal` 4, `tutorialBoardSize` 3, `tutorialMassTonnes` 5/12/20, `handlingGameHoursPerTonne` 0.02, `loanRepaymentShare` 0.3, `dealLoanAmount` 5000, `startingCredits` 500. "Unmarked crates" scripted contract (run 3, ×2) and six onboarding goals (`src/data/onboarding.ts`). Step 2.5 test replaced per CR §6; Market lists purchasable models only and the server will not sell the loaner.
- [x] **Step 10A.2 — Sim: handling time.** `travelTimeGameHours(ship, distance, massTonnes, config)` adds `mass × handlingGameHoursPerTonne`; dispatch records pass the contract mass (0 for repositions); client predictions pass contract mass. Step 3.5 hand-calculated test updated.
- [x] **Step 10A.3 — Sim: tutorial board v2.** `generateTutorialBoard({ loanerLocationId, runsCompleted, periodIndex })`: light/medium/full Standard contracts at the tutorial share; a scripted contract for the upcoming run replaces the medium slot (`scriptedId` on the contract, at its pay multiplier). Loaner is `config.tutorialLoanerShipModelId`. Step 3.10 tests replaced. Server passes `runsCompleted: 0` until Step 10A.7.
- [x] **Step 10A.4 — Sim: loan repayment.** `splitLoanRepayment(credits, balance, share)` (`src/loan.ts`); `resolveDispatch` takes `loanBalance` and returns `loanRepayment` with net `credits`. Server passes a zero balance until Step 10A.9.
- [ ] Step 10A.5 — Sim: onboarding goal evaluation
- [ ] Step 10A.6 — Schema and database
- [ ] Step 10A.7 — Server: tutorial flow v2
- [ ] Step 10A.8 — Server: accept the deal
- [ ] Step 10A.9 — Server: loan repayment
- [ ] Step 10A.10 — Server: goals
- [ ] Step 10A.11 — Client: first launch goes straight to work
- [ ] Step 10A.12 — Client: tutorial board shows the tradeoff
- [ ] Step 10A.13 — Client: the deal
- [ ] Step 10A.14 — Client: loan on HQ
- [ ] Step 10A.15 — Client: goals on HQ
- [ ] Step 10A.16 — Client: whole map from the start
- [ ] Step 10A.17 — Client: something waiting on return
- [ ] Step 10A.18 — Plan amendments and regression
