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.
