Merge pull request 'v1.10.0: top-bar Log out (ISS-157) + Admin button gated to admins (ISS-158)' (#164) from feat/topbar-logout-admin-gate into master

- actions/hover/two-planes: FAST=10_000 for expiry fast-forwards, landing
  waits and fly-home cleanups; queue: + CHAIN=4_000 for auto-chain
  observation, refuel test at explicit 2_000 with relaxed fuel bound
- map-interactions: FAST=50_000 chain hops (~3 min -> ~15 s per direction);
  crossing leg stays at SCALE and now sets it BEFORE dispatch (a leftover
  fast rate would let the dispatch tick consume most of the leg)
- hover fleet-row test asserts flying from the fly endpoint's own snapshot
  and freezes immediately instead of speeding up then freezing mid-leg
- two-planes parallel-flight: both-grounded poll after cleanup dispatches so
  afterEach heal no longer pays the range-edge return leg at SCALE

 # Changelog
 
+## v1.10.0 — 2026-09-27 22:31
+- **Top-bar Log out (ISS-157).** New `Log out` button as the last child of the top bar (`components/Map.tsx`) — flex row puts it top-right, no CSS. Same three steps as the admin panel's in-modal button: best-effort `POST /api/logout` with the session header, clear the stored session id, drop back to the sign-in screen via the existing `onLogout`. The two in-modal Log out buttons are kept (zero e2e churn).
+- **Admin button only for admins (ISS-158).** The top-bar `Admin` button now renders only when `/api/me` reports `admin: true` — hidden entirely, not disabled. No server change: the endpoint already returns `{username, admin}`; `app/page.tsx` now parses that body on its mount probe and passes `isAdmin` down AppShell → Map. The probe also re-runs after a form sign-in (bumped `probeKey`) so `isAdmin` tracks the user who just signed in, not whoever was probed before — an admin logging out followed by a non-admin signing in no longer sees the Admin button.
+- **E2E.** New test in `e2e/map.spec.ts`: top-bar Log out → sign-in form visible and app header gone (mirrors the existing admin-panel logout assertion).
+
+## v1.9.0 — 2026-09-27 20:57
+- **E2E speedup follow-up (test-only, no game code changed).** `e2e/relocation.spec.ts`'s self-heal helper `flyHomeViaApi` now fast-forwards its cleanup legs at the v1.8.0 `FAST = 10_000` rate instead of a blanket `SCALE = 1000` — every scale-dependent wait in that file is a pure arrival wait (status `'available'` / `locationIcao === HUB`) with no mid-leg observation, so the higher rate is safe and the now-unused `SCALE` constant was dropped. Expected CI wall time for the file drops from ~40 s to ~25 s (~2–3 s off test 1, ~10–11 s each off tests 2 and 3). Test 3's deliberate `setScale(page, 1)` guard is untouched; `map.spec.ts` wheel-zoom (real-time-bound) and `multiplayer.spec.ts`'s N-player clock (measures sim-vs-real elapsed time) stay as-is.
+
+## v1.8.0 — 2026-09-27 20:13
+- **E2E speedup (test-only, no game code changed).** Every Playwright spec that fast-forwards legs now uses the fastest rate its assertions allow instead of a blanket `SCALE = 1000`: pure arrival waits (no mid-leg observation) run at `FAST` — a lagged tick can only land a plane sooner, never skip an observed state. Expected CI wall time for the affected tests drops ~5–6× overall (e.g. the antimeridian test's relocation chains go from ~3 min to ~15 s per direction; two-planes' parallel-flight test loses its ~24 s afterEach heal leg).
+- **Per-test rates.** `actions.spec.ts` + `hover.spec.ts` + `two-planes.spec.ts`: new local `FAST = 10_000` for expiry fast-forwards, landing waits and fly-home cleanups. `queue.spec.ts`: same `FAST`, plus `CHAIN = 4_000` for the auto-chain observation (max per-tick advance 2 s × S stays below the LEMD-length leg's ~1e7 sim-ms duration so one lagged tick can't complete it before a poll sees the chained state); its refuel-before-chained-leg test moves to an explicit `2_000` with the fuel lower bound relaxed from `> 1.3×required` to `> required` (at 2_000× the snapshot can land ~0.4×required into leg 2's burn under dind load; a wrong top-up level still lands far below the bound, and the exact level stays pinned by the unchanged cash assertion). `map-interactions.spec.ts`: `FAST = 50_000` for chain hops (≤3400 km each) and arrival waits.
+- **Kept at SCALE = 1000 where mid-leg observation is real.** The antimeridian crossing leg itself (freshness gate ~700 km ≈ 5 s of flight + >3 fresh samples assume ~14 s of real-time flight), the queue spec's final-hop chain window (EHAM→EDDF is only 2_587 sim-s — at higher rates a `/api/state` 500-retry gap could advance past it), and map-interactions' mid-flight click window. The antimeridian crossing dispatch now sets SCALE BEFORE the fly POST: with FAST-rate chains, a leftover fast rate would let the dispatch tick itself consume most of the leg before the setScale lands (flake path).
+- **hover.spec.ts fleet-row test restructured.** It no longer speeds up to 1000× and then freezes mid-leg; it asserts `flying` from the fly endpoint's OWN post-action snapshot (no poll race) and freezes at scale 1 immediately — same pattern as its package-hover sibling, so the ~10 s leg can't land under the assertions.
+- **two-planes parallel-flight test.** Landing waits move to FAST, and a new both-grounded poll after the cleanup dispatches lets the range-edge return legs finish while the clock is still at FAST — previously afterEach's `healPlaneHome` paid that ~24 s leg back at SCALE.
+
+## 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.
+- **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.
