 # Changelog
 
+## v1.5.0 — 2026-09-26 19:06
+- **Multiplayer step 7/12 (ISS-111): shared-world spawn quality rule.** The #101 decision point is resolved with the agreed default proposal: spawned pool packages scale to the MAX reputation across ALL player rows, so job rewards track the best-progressed player and nobody is stuck on low-rep jobs. New `getSharedWorldReputation(inst)` in `lib/db/localPlayer.ts` — one SQL `MAX(reputation)` over the players table, 0 when there are no players (the rep bonus floors at ×1 either way). The engine's pool spawner (`spawnPoolPackages`, `lib/sim/engine.ts`) reads it once per spawn batch and passes it through `generatePoolPackage(..., reputation)`, replacing the last singleton `getLocalPlayer` job-quality read; the env-gated `/api/test/create-package` hook — which documents itself as carrying "the same job quality as engine spawns" — follows the same rule so no surface can drift.
+- **Sites that stay on 'local' (deliberate).** The seeded local row is still inserted at first-run seeding (`lib/db/client.ts`) and staged by the env-gated `/api/test/*` economy hooks (add-cash, set-cash) — those stage an account, not job quality. Seed-time package generation (`buildSeed`) passes no reputation at all and keeps defaulting to `STARTING_REPUTATION`, so fresh worlds are byte-identical to before.
+- **Tests.** Unit: two new engine tests in the `spawnPoolPackages` suite — with a second player at rep 60 vs local's starting rep, every spawned package's reward matches an independent recomputation (rewardFor × rep bonus × special multiplier) at the MAX and provably not at local's; single-player regression guard asserts one row ⇒ quality is that row's own reputation, identical to the pre-v1.5.0 singleton read. No e2e spec changes: CI plays a single minted player, where MAX equals that player's rep — behavior unchanged.
+
+## v1.4.0 — 2026-09-26 18:35
+- **Multiplayer step 8/12 (ISS-112): per-player snapshot + shared market view with owner info.** The state snapshot is now a true SHARED-WORLD view on every surface that serves it. `getStateSnapshot(playerId)` in `lib/game/state.ts` gains two additive fields: every plane row carries `ownerId` + `ownerName` (players.username via planes.owner_id — the snapshot lists ALL planes, so panes can tell whose plane is whose), and every package row carries `carrierName` (players.username of the carrying plane's owner, joined package → planeId → planes.owner_id → players; null when unassigned). One players-table read per projection serves both joins. `account` stays the acting session player's row (v1.3.0) — no renames or removals anywhere, so existing clients and e2e assertions keep working unchanged.
+- **SSE frames are now PER PLAYER.** The #101 decision point is resolved: visibility of other players' planes is ON by default — there is no toggle (a shared world you can't see in is pointless; nobody asked for a privacy switch). `lib/sse.ts` keys its subscriber registry by player id (`subscribe(playerId, fn)`, new `subscribedPlayerIds()`), and the engine's tick broadcast (`broadcastState` in `lib/sim/engine.ts`) projects ONE snapshot per connected session's player id — N clients = N projections per tick, N is tiny — fanning each frame out to that player's group only. Every client now sees its own account row in every pushed frame instead of the seeded local player's. The connect frame and all pushes come from the SAME shared projection (`getStateSnapshot` + `sseFrame`), as does GET /api/state, so no two surfaces can drift; `/api/events` subscribes under `auth.player.id`.
+- **UI.** Left pane fleet rows show an owner badge (username) next to the model name — every plane in the world is visible and labeled. Right pane open-package rows show a carrier-name badge when `carrierName` is set (open packages are unassigned today, so it renders once assignment lands; the join + render path exist now). One small `.owner-badge` style mirrors `.special-badge`.
+- **OpenAPI.** `PlaneState` gains required `ownerId`/`ownerName`; `PackageState` gains required nullable `carrierName` — documented in `lib/openapi.ts`, path count unchanged at eighteen.
+- **Tests.** Unit: `lib/sse.test.ts` reworked for the keyed registry (per-player isolation, empty-group drop, throwing subscriber, idempotent unsubscribe); new `/api/state` route tests assert all planes carry owner info including a foreign player's plane, and that carrierName joins through planeId → owner_id → username while unassigned packages stay null; new `/api/events` test opens TWO streams (local + a second minted player) and asserts each tick push carries the stream's OWN account row — plus connect-frame parity assertions (owner fields present, same projection as GET). Fixture helpers in `state.test.ts`, `deriveEvents.test.ts`, `right-pane.test.ts`, `mapData.test.ts` gain the new fields. No e2e spec changes: all pane/API assertions are additive-safe (`toContainText`, per-key `toHaveProperty`), and CI's existing suite covers the UI paths.
+
+## v1.3.0 — 2026-09-26 17:05
+- **Multiplayer step 6/12 (ISS-110): per-player money & reputation in the engine + snapshot.** The last singleton economy accesses are converted to per-player rows. `deliverPackages` (`lib/sim/engine.ts`) now pays cash + reputation to the DELIVERED PLANE'S OWNER row (`plane.owner_id`, fresh read per award so multiple deliveries in one tick all count), and the ISS-082 auto-chain top-up debits the same owner's row with their own rep discount — a plane owned by player B earning or refueling never touches any other account. `getStateSnapshot(playerId)` sources the snapshot's `account` field from the ACTING SESSION player's row; the field name/shape (`{cash, reputation}`) is unchanged and OpenAPI stays untouched. Session-scoped callers thread it: `/api/state`, every action response (`performAction`) and the SSE connect frame all pass `auth.player.id`.
+- **Sites that stay on 'local' (deliberate).** The shared SSE broadcast has no acting session — it passes `LOCAL_PLAYER.id` until per-player frames land (#112). The engine's pool-spawn job-quality read stays on the seeded local row: pools are SHARED world state (packages have no owner), so there is no single owning player whose rep should set quality; a ponytail comment names #112 as the decision point. The env-gated `/api/test/*` economy hooks (add-cash, set-cash) remain admin-style tools with no session — they stage the SEEDED local account, which is exactly the player the e2e suite plays via `mint-player-session`'s default; create-package's job-quality read matches the engine spawn.
+- **Tests.** Unit: two new engine tests in `lib/sim/engine.test.ts` — a plane owned by player B delivers → B's cash/rep increase and local is untouched (both directions), and an empty-tank landing with a queued leg debits the top-up from B (B's rep discount) while local stays put; new `/api/state` route test mints a second account with a distinct economy and asserts `account` carries THAT session player's row. All existing suites pass unchanged — every seeded plane is owned by 'local', so single-player behavior is byte-identical. No e2e spec changes: the minted e2e session IS the local player, and CI's existing suite covers the UI paths.
+
+## v1.2.0 — 2026-09-26 16:25
+- **Multiplayer step 4/12 (ISS-108): per-player onboarding.** New registrants start with a starter plane at EDDF, not just cash: `buildStarterPlane(airports, id)` is extracted from `buildSeed` in `lib/game/seed.ts` (byte-identical values to the fresh-install seed — same model, full tank, hub location, no RNG draws; only the id differs) and reused by `POST /api/register`, which inserts it owned by the new player. The test-only mint hook does the same for custom usernames, so e2e-created accounts are onboarded like real ones. ponytail comment marks legacy players without planes (pre-v1.2.0 test mints) as out of scope — they keep exactly what they had.
+- **Multiplayer step 5/12 (ISS-109): `planes.owner_id` + ownership checks.** New `owner_id TEXT NOT NULL` column in the raw DDL and Drizzle mirror; one-time guarded migration (`migrateColumns`, PRAGMA table_info check) backfills every pre-v1.2.0 row to `'local'` via SQLite's constant ALTER default, so a migrated world's planes all belong to the seeded local player exactly as before — idempotent on second open. All seven plane actions plus `repairPlane` now take the session player's id and reject foreign planes with 403 "not your plane" through one shared `assertPlaneOwner()` (checked right after the 404 fetch, so ownership errors win over state errors); `performAction` passes `auth.player.id` as its callback's second argument, keeping every route a pure pass-through. Economy is per-player: new `getPlayer(inst, id)` / `updatePlayerEconomy(inst, id, patch)` in `lib/db/localPlayer.ts` replace the local-only helpers at every action call site (a non-local buyer now debits their own cash; `getLocalPlayer` stays for the snapshot and engine until per-player views land). The sell-plane last-plane guard is PER OWNER — you can't sell your last plane even if other players' planes exist, and selling one of two of yours is fine. `buyPlane` stamps the buyer as owner of the delivered plane.
+- **Mint hook default → kamilkrzywda.** The e2e specs play with the seeded world's planes by id (`plane-starter`), so the no-body mint now resolves to the existing local player that owns them after backfill — creating NO new rows; a custom username still creates a fresh account, now WITH onboarding. `e2e/auth.ts` and every spec are untouched: they keep working because the session they mint is the owner's.
+- **OpenAPI.** The seven plane-targeted action endpoints document the new 403 (buy-plane has no plane target, so it gains none); path count unchanged at eighteen — `openapi.test.ts`'s per-endpoint error-code lists updated to match.
+- **Tests.** Unit: new backfill migration test in `lib/db/client.test.ts` builds a pre-v1.2.0 file (two planes without owner_id) and verifies open() backfills both to `'local'`, does not re-seed, and is a no-op on second open (a post-migration owner change survives reopen); new ownership suite in `lib/game/actions.test.ts` — 403 for every action when the session player doesn't own the plane (both directions), per-owner last-plane guard against the world total, buyer stamped as owner with their own cash debited and local's untouched; register + mint route tests assert exactly one onboarding plane at EDDF owned by the new account. All 74 existing action call sites in `actions.test.ts` now pass `'local'`; no e2e spec changes needed (the minted session is the owner's).
+
+## v1.1.0 — 2026-09-26 14:39
+- **Multiplayer step 3/12 (ISS-107): every game route is session-guarded; new accounts can register.** `lib/auth.ts` grows a shared guard on top of the v0.71.0 session plumbing: `requireAuth(req)` (X-Flight-Session header) and `requireAuthSse(req)` (header OR `?session=` query — EventSource cannot set headers), both returning either `{ok, inst, user, player}` or a ready-made 401/500 response. The guard joins `players` on the account's username, so the seeded admin resolves to the v1.0.0 local player row; an account with no players row is a data error → 500. Coverage: `/api/state`, all eight action routes (one `performAction(req, fn)` call site in `lib/game/actions.ts` guards them all), and the SSE stream (`/api/events`, validated at connect — ponytail comment names the mid-stream ceiling). Exempt by design: `/api/version`, `/api/openapi`, `/api/airports`, `/api/login`, `/api/register`, `/api/logout`, `/api/me`, the admin CRUD (own guard), and every `/api/test/*` hook.
+- **POST /api/register.** Strict body validation (exactly `username` + `password`; unknown fields 400); username lowercased, then 3–20 chars of `[a-z0-9_-]` else 400; password ≥8 chars else 400; 409 when taken. Creates the users row (scrypt via the same `hashPassword()` login verifies) AND a players row with the starter economy (`STARTING_CASH`/`STARTING_REPUTATION`) — one randomUUID shared by both rows — then mints a session immediately and returns `{sessionId, user}` like `/api/login`, so sign-up needs no second round-trip.
+- **Sign-in screen replaces the shell until authenticated.** New `components/SignInScreen.tsx`: full-screen dark panel with two forms (sign in / create account) sharing one submit path; errors surface in a single `role=alert` line. `app/page.tsx` gates on it: stored session → `/api/me` check on mount (stale id cleared, network error falls through to sign-in), then the game shell mounts only when authenticated — so an unauthenticated browser never polls `/api/state`. New client module `lib/authClient.ts` owns the localStorage key (`flight.session`) and builds the `X-Flight-Session` header; every app fetch (state poll, SSE URL, action POSTs, fly/queue in Map) now carries it. Admin panel logout drops back to the sign-in screen via a new `onLogout` prop (page → Map → AdminPanel).
+- **E2E session hook + spec updates.** New test-only `POST /api/test/mint-player-session` (FLIGHT_TEST_HOOKS=1, 404 elsewhere — like its `/api/test/*` siblings): creates the users+players rows for a username if missing and mints a session, idempotent across container restarts since the CI DB volume persists. `e2e/auth.ts` mints + applies it per test (context extraHTTPHeaders for spec-side requests, localStorage init script for the app's own fetches); every guarded-route spec authenticates in a beforeEach; events.spec uses the real client path (`?session=`); api.spec/openapi tests track the new eighteenth endpoint. Admin spec reworked: unauthenticated visitors see the sign-in screen (no shell), wrong credentials error there, and logout returns to it.
+- **Tests.** Unit: new `lib/auth.test.ts` (hash round-trip; 401 on missing/unknown/expired session; admin→local player join; 500 on missing players row), register route tests (validation matrix, shared-id rows + starter economy + minted session, case-insensitive 409) and mint-hook tests (gate off → 404 even with CI's FLIGHT_TEST_HOOKS=1 env — stubbed explicitly, default-username creation, idempotent re-mint, bad usernames). All existing state/events/action route tests now mint a session for the seeded admin user in beforeAll. OpenAPI: `/api/register` documented (RegisterRequest schema; 200/400/409) — spec is now eighteen paths.
+
 ## v1.0.0 — 2026-09-24 14:20
 - **Multiplayer step 1/12 (ISS-105): `players` table replaces the singleton `account`.** New `players` table (`id TEXT PK`, `provider`, `username`, `cash REAL`, `reputation REAL`) in the raw DDL (`lib/db/client.ts`) and a matching Drizzle entry (`lib/db/schema.ts`; `AccountRow` → `PlayerRow`). **One-time migration**: on every `open()`, if the legacy `account` table still exists (sqlite_master check, same guard style as the v0.12.0 contracts migration) AND `players` is empty, its single row is copied into a seeded local player — id `local`, provider `local`, username `kamilkrzywda` (so a later step can join players↔users on username) with cash/reputation carried over — and `account` is dropped. Idempotent: fresh DBs never have `account`, already-migrated files no longer do either, so it runs exactly once per legacy file. **Fresh worlds**: the DDL no longer creates `account`; first-run seeding (empty-check flipped from `COUNT(*) FROM account` to `players`) inserts the local player row directly with the same starting cash/reputation as before.
 - **No behavior change — temporary single-player helper.** Every pre-multiplayer read/write of the singleton economy now goes through ONE small module, `lib/db/localPlayer.ts`: `getLocalPlayer(inst)` (resolves the `players` row where id = 'local', throws if missing) and `updateLocalPlayerEconomy(inst, {cash?, reputation?})`. Call sites converted: snapshot (`lib/game/state.ts`), all five actions (`flyPlane` refuel, abandon penalty, buy/sell plane, repair — `lib/game/actions.ts`), the engine's delivery awards + chain top-up + spawn reputation read (`lib/sim/engine.ts`), and the three test hooks (add-cash / set-cash / create-package). The `/api/state` snapshot keeps its exact `account: {cash, reputation}` field name and values, so OpenAPI is untouched — 17 paths, same schemas.
