Progress

Phase 1 — Repository Setup

• 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).
• 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().
• 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.
• 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.
• 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

• 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.
• 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.
• 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.
• 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.
• 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.
• 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

• Step 3.1 — Game clock conversion. src/clock.ts: realToGame / gameToReal using the config epoch and compression; times are Unix-ms numbers.
• Step 3.2 — Seeded RNG. src/rng.ts: createRng(seed) (mulberry32) with next, int, pick; deriveSeed(parent, label) for child seeds.
• 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.
• Step 3.4 — Route distance. src/distance.ts: routeDistance(from, to, gameTime), straight-line million km.
• Step 3.5 — Travel time. src/travel.ts: travelTimeGameHours(ship, distance) = cruise time + overhead.
• Step 3.6 — Fuel cost. src/fuel.ts: fuelCost(ship, origin, distance) = distance × cost per million km × origin launch multiplier.
• 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.
• Step 3.8 — Contract model and payout
• Step 3.9 — Contract board generation
• Step 3.10 — Tutorial contract board
• Step 3.11 — Pilot eligibility
• Step 3.12 — Dispatch validation
• Step 3.13 — Dispatch record creation
• Step 3.14 — Reposition dispatch
• Step 3.15 — In-flight position and progress
• Step 3.16 — XP and leveling
• Step 3.17 — Dispatch resolution
• Step 3.18 — Sim package public API and coverage
