 # Changelog
 
+## v1.7.0 — 2026-09-26 20:24
+- **Multiplayer step 12/12 (ISS-116): multiplayer test coverage.** The final campaign step closes the two remaining verification gaps with tests only — no production game code changed: the #135 freeze rule (`shouldAdvanceTime`) already counts ALL planes regardless of owner, and the mint hook has supported a username override since v1.1.0 (the e2e helper just never forwarded it).
+- **E2E.** New `e2e/multiplayer.spec.ts` (serial) plays two live sessions: player A is the suite's usual local player; player B is a second account minted through the same hook with a username override. Test 1 verifies the N-player clock end-to-end (#135 × ISS-113): while A flies and B stays grounded, the world clock advances on every read (one owner airborne is enough to keep time moving), then after A lands — EVERY player grounded — the clock freezes exactly across ~2.5 s of real idleness. Test 2 verifies ownership isolation: both sessions see the same shared fleet with `ownerId`/`ownerName`, A gets 403 "not your plane" on B's starter (fly AND sell — the 403 must beat B's last-plane 409), B gets 403 on A's, a grant to local moves only A's account row while B's stays untouched, and both sessions see the v1.6.0 `players` summary with per-owner plane counts.
+- **Test hooks.** `e2e/auth.ts`'s `mintPlayerSession(page)` now forwards an optional username (the route already supported it). New FLIGHT_TEST_HOOKS-gated `POST /api/test/delete-plane {username}` — deletes every plane owned by that player's row (any bound packages unbound first), idempotent for unknown usernames, returns the local-scoped snapshot like its siblings. Needed because B's onboarding starter is unsellable (per-owner last-plane guard) and would break later specs' single-fleet self-heal within the same CI run; an `afterAll` deletes it even when tests fail.
+- **Tests.** Unit: two new engine tests — a tickOnce-level N-player clock test (A flying + B grounded → advances at exactly the fixed world rate; all owners grounded → frozen with the real-time anchor still tracking, ISS-113) and the symmetric spawn-quality case (local leads → MAX picks local's row, not "prefer non-local"). No existing e2e spec changed: they are additive-safe against a second player.
+
+## v1.6.0 — 2026-09-26 19:35
+- **Multiplayer step 11/12 (ISS-115): leaderboard panel.** Small UI listing every player in the world with cash, reputation and plane count, rendered from snapshot data — no new endpoint. The known gap from step 8 is closed additively: `getStateSnapshot(playerId)` (`lib/game/state.ts`) now projects a `players` array (`PlayerSummary[]`: `{ id, username, cash, reputation, planeCount }`, planeCount = planes owned) into the ONE shared snapshot projection, so GET /api/state, action responses and every SSE frame all carry it in sync automatically. No extra query — the players rows were already loaded for the v1.4.0 owner joins; plane counts are a single in-memory pass over the already-loaded plane rows.
+- **UI.** New "Leaderboard" button on the right side of the map top bar (next to Admin) opens the panel as a modal, reusing the existing `Modal` + `.pane-btn` conventions — per the 2026-09-23 placement decision it is NOT embedded in the left pane. New `components/Leaderboard.tsx`: one row per player (username, cash via `formatCash`, reputation, plane count), sorted by reputation descending with cash then username as deterministic tie-breaks so rows don't shuffle between snapshots on equal rep. Small `.leaderboard` table styles mirror `.admin-rows`.
+- **OpenAPI.** New `PlayerSummary` schema; `StateSnapshot` gains required `players: PlayerSummary[]` — documented in `lib/openapi.ts`, path count unchanged at eighteen.
+- **Tests.** Unit: new `getStateSnapshot players` suite in `lib/game/state.test.ts` against a throwaway seeded DB — single-player regression guard (exactly one row for the seeded local account with its starter plane) and a two-player case asserting cash/reputation/planeCount per owner (local keeps 1, player B counts both of its planes). The `/api/state` route test's exact key-list assertion gains `players`; all four typed snapshot fixtures (`state.test.ts`, `mapData.test.ts`, `deriveEvents.test.ts`, `right-pane.test.ts`) gain the new required field. No e2e spec changes: existing specs assert per-key `toHaveProperty` on planes/packages only, and CI's single minted player sees a one-row leaderboard — behavior unchanged; the button/modal wiring is covered by tsc + the modal pattern already exercised in admin.spec.ts.
+
+## 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.
