Step 10B.7: Contracts screen by location with idle-ship badges

 - **Another player's bay id is `404 not-found` ("You have no such bay")**, the same as an id that does not exist, so ids of other players' bays are not confirmed. It is checked after the model and before any credits are spent.
 - **`SHIPYARD_LOCATION_ID` is gone:** the delivery location is always the chosen bay's.
 - **Interim client:** the Market buys for the player's first bay (always Earth today) so the build stays green; Step 10B.9 replaces this with the "Deliver to which HQ?" picker.
+
+## Step 10B.7
+
+- **`Ship.lastArrivalAt` is never null:** the latest resolved arrival of that ship, else its delivery time (`created_at`). A newly bought ship counts as having just arrived at its bay, which is what the default-location rule wants.
+- **The selector is a wrapping row of location buttons (`aria-pressed`), not a `<select>`**, because each entry carries an idle-ship badge; a native option cannot hold one. Locations without idle ships show no badge.
+- **The URL is the source of truth for the selection** (`?location=`, replacing `?bay=`), so "Find work here" and the map link work even when Contracts is already open. An undiscovered or unknown id falls back to the default.
+- **A hint shows when no idle ship is at the selected location**, pointing to deadheading from the Fleet. The old "no bays yet" message is gone: every player can see Earth's market.

 - [x] **Step 10B.4 — Server: board endpoint for any discovered location.** `getContractBoard` is now `GET /api/locations/:locationId/board` (`locationBoard` in `src/game/boards.ts`): any discovered location, no bay needed; `409 location-undiscovered` for undiscovered, `404` for unknown. Step 6.9 tests moved to `location-board.test.ts`.
 - [x] **Step 10B.5 — Server: no more stranded ships.** Contract and deadhead dispatch never consulted bays after 10B.2/10B.4; this step proves it. `stranded.test.ts` covers the original bug: a Courier delivers Earth→Moon with no Moon bay, takes a Moon→Earth job from the Moon board and lands at Earth; separately it deadheads Moon→Earth. The Step 6.11 test now deadheads to the Moon without a Moon bay.
 - [x] **Step 10B.6 — Server: ship delivery to a bay.** `buyShip` takes `{ modelId, bayId }`; the ship appears idle and uncrewed at that bay's location. Missing `bayId` is `400 validation-error`; a bay the player does not own is `404 not-found` with nothing changed. The Market sends the first bay's id until the 10B.9 picker. Test helpers return `earthBayId`.
-- [ ] Step 10B.7 — Client: Contracts screen by location
+- [x] **Step 10B.7 — Client: Contracts screen by location.** `LocationBoards` (was `BayBoards`) shows a Location button group of every discovered location with an idle-ship count badge, defaulting to the most recently arrived idle ship's location (else Earth); `?location=` selects one (map link and Fleet's new "Find work here"). API: `Ship.lastArrivalAt`. Tests: `location-boards.test.tsx`, `last-arrival.test.ts`.
