 # Changelog
 
+## 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.
+- **Tests.** Unit: fresh DB now asserts the seeded local player row (`local`/`local`/`kamilkrzywda`, starting cash/reputation) AND that no `account` table exists; new dedicated migration test builds a minimal legacy file containing only an `account` table and verifies open() copies its row into the local player, drops `account`, and is a no-op on second open. All existing suites (actions, engine, client, buy/sell/abandon routes) now read/write through the helper; the admin rows CRUD test's PK-less-table example moves from `account` to `sim_state` (the only remaining PK-less table), and the admin tables-list expectation swaps `account` → `players`. No new e2e spec — behavior is byte-identical and CI's existing suite covers the UI paths; a fresh-stack boot exercises the new seed path.
+
+## v0.73.0 — 2026-09-24 12:24
+- **New-package toasts removed.** The client-side snapshot diff in `lib/deriveEvents.ts` no longer emits "New package available" info toasts when a contract appears (the user was spammed by them); the first-snapshot guard and every other event type — delivered, expired, landed, bought, sold — are unchanged.
+
+## v0.72.0 — 2026-09-24 11:44
+- **Admin login fixed.** The seeded admin's scrypt digest in `lib/db/client.ts` was computed with different parameters than the verifier (`verifyPassword()` passes the salt as a plain string to `scryptSync(pw, saltHex, 32)`), so real logins failed with 401 "invalid credentials" since v0.71.0. The seed now carries a digest produced by exactly that call (the plaintext still exists nowhere in code, tests or comments). Because the seed is `INSERT … WHERE NOT EXISTS`, pre-existing databases keep their old row — so every `open()` also runs an idempotent rotation (`UPDATE users SET password_hash = ? WHERE id = 'admin-kamilkrzywda' AND password_hash != ?`): a no-op once healed, it repairs legacy rows at boot and is durable on the next persist. Unit tests cover the fresh seed with the new digest plus the rotate-on-open path (legacy file heals to the current digest; second open is a no-op).
+
+## v0.71.0 — 2026-09-24 09:18
+- **Admin panel.** A new "Admin" button on the right of the top bar opens a reusable modal (`components/Modal.tsx` — fixed overlay at z-index 60, above the z-50 toast stack; centered `role="dialog"` panel; closes on Escape and backdrop click) hosting `components/AdminPanel.tsx`. No new URL routes: everything lives behind that one button + modal.
+- **Users + sessions tables.** New `users` (id PK, unique username, scrypt `salt$hex` password_hash, admin flag, created_at) and `sessions` (UUID id, user_id, 7-day expires_at) tables in the raw DDL (`lib/db/client.ts`) and typed Drizzle entries (`lib/db/schema.ts`). An **idempotent seeded admin** is inserted on every `open()` — user id `admin-kamilkrzywda`, username `kamilkrzywda`, admin=1, hash-only (the plaintext exists nowhere in code, tests or comments) — guarded by `WHERE NOT EXISTS` so pre-existing production DBs gain exactly one row and never a duplicate. The users table is also the foundation for multiplayer auth (#105/#107).
+- **Auth API.** `POST /api/login {username,password}` verifies with node:crypto `scryptSync` + `timingSafeEqual`; an unknown username still runs one full scrypt against a fixed dummy digest so timing stays uniform. Success mints a 7-day session (lazy cleanup of expired rows) and returns `{sessionId, user:{username,admin}}`. `POST /api/logout` deletes the session named by the new `X-Flight-Session` header (idempotent); `GET /api/me` resolves it to the current user or 401. The client stores the sessionId in localStorage (`flight.session`) and sends the header on every authenticated request.
+- **Generic whole-database CRUD behind the admin flag.** `lib/auth.ts`'s `requireAdmin` guard (no/expired session → 401, non-admin → 403) runs before any input is touched on: `GET /api/admin/tables` (user tables, sqlite_% excluded) and `GET|PUT|POST|DELETE /api/admin/tables/{name}/rows` — rows carry their rowid as `__rowid` so the PK-less tables (account, sim_state) are editable like any other; PUT updates only changed cells, POST inserts, DELETE removes by rowid. SQL safety: table names quoted only after sqlite_master validation, column names validated against PRAGMA table_info, values ALWAYS bound as parameters — no user input is ever concatenated into SQL.
+- **UI.** The Admin modal shows a login form (wrong credentials show an error line), a "not an admin" notice for authenticated non-admins, or the grid: table list → per-table editable rows (each cell an input; per-row Save/Delete, "+ Add row", Refresh) with logout in the header area. Deliberately plain — it's a dev tool surface, not a product feature.
+- **Test hook.** `POST /api/test/admin-session` (FLIGHT_TEST_HOOKS=1 gate like its siblings) mints a session for the seeded admin server-side and returns `{sessionId}` — so the e2e suite can exercise the authenticated panel WITHOUT the real admin password ever appearing in test code.
+- **OpenAPI.** Five new paths documented (`/api/login`, `/api/logout`, `/api/me`, `/api/admin/tables`, `/api/admin/tables/{name}/rows` with all four verbs) plus their request/response schemas; endpoint count twelve → seventeen everywhere it is asserted (unit + e2e).
+- **Tests.** Unit: the idempotent admin seed (fresh DB, reopen, and a legacy pre-v0.71.0 file), login success/wrong-password/unknown-username/malformed bodies with an in-test scrypt hash for a self-created user (the real admin's plaintext is never referenced), logout idempotency, /api/me with missing/unknown/expired/live sessions, the guard ladder (401 no header, 401 expired, 403 non-admin) and the full CRUD validation matrix (rows incl. `__rowid` for account, PUT-verified-by-refetch, POST+DELETE round-trip, unknown table 404, unknown column/bad limit/missing rowid 400). E2E (`e2e/admin.spec.ts`, CI-only): open modal → login form → wrong creds error → hook-minted session via localStorage → table list incl. packages/users → edit a cell + Save verified by an independent re-fetch → add + delete a users row → logout back to the login form.
+
 ## v0.70.0 — 2026-09-23 22:07
 - **Default map view is now the whole world.** The initial camera in `components/Map.tsx` moves from the Europe overview `[10,52]` z4 to null island `[0,0]` (renamed constant `WORLD_CENTER`) at zoom 2 — at z2 the world is 2048 px wide and the Africa+Europe bounding box (lat −35..+71, lon −18..+52) spans ~800 px vertically in Web Mercator, so both continents are fully visible on a typical desktop map pane. `MIN_ZOOM` is lowered 3 → 0: when fully zoomed out the whole earth (512 px world) fits any viewport; `MAX_ZOOM = 11` and the flat-2D view are unchanged.
 - **E2E.** The new default view shows both Africa + Europe with overlapping markers — LFRS's nearest neighbour (LFRB Brest, 254 km) is only ~13–19 px away at z2, so every marker-click spec now frames its target first: `e2e/map.spec.ts` gains a shared `frameLfrs` helper (`jumpTo` z5 + wait until the marker renders), used by all three of its click tests; `e2e/map-interactions.spec.ts` and `e2e/relocation.spec.ts` frame LFRS at z5 before their popup clicks. The plane-marker test in `e2e/map-interactions.spec.ts` fits EDDF+LEMD into the viewport first — `queryRenderedFeatures` is viewport-scoped and EDDF (50°N) sits right at the edge of the new default view. `e2e/hover.spec.ts`: the antimeridian test's `setMinZoom(0)` workaround is deleted — minZoom is natively 0 now, so `fitToAirports` can reach the z≈1 that EDDF→NFTF needs without lifting any floor. New assertion in `e2e/map.spec.ts` pins the initial camera to [0,0] z2; the wheel-clamp spec's MIN_ZOOM mirror is updated 3 → 0 (its zoom-out side now clamps at 0).
