Merge pull request 'v0.9.4 — top bar shows app version instead of ◄ SHIP (#23)' (#25) from topbar-version into master

Pin the wide layout to the viewport (height:100vh + overflow:hidden on the
root), add min-height:0 to the BODY wrapper and 3-column grid so the flex
chain actually constrains, and make the OPERATIONS panel a flex column whose
PanelContent is the scroll area (header stays pinned; the Panel root's default
overflow:hidden would otherwise clip). Columns' existing overflow-y:auto now
scrolls inside their tracks. Narrow mode keeps natural body flow.

 # Changelog
 
+## v0.9.4 — 2026-09-29 08:29
+- Top bar (#23): the `◄ SHIP` label in the mission control header is replaced with the app version number (e.g. `v0.9.4`). The header reads it from `package.json` via the same `@/package.json` import that `/api/version` and the OpenAPI spec use, so there is a single source of truth — no second hardcoded copy.
+- e2e: no spec changes needed — no spec asserted on the old `◄ SHIP` label (the landing-page test only checks the SpaceWanderer heading). All 15 specs compile unchanged.
+
+## v0.9.3 — 2026-09-29 08:20
+- Layout (#21): only the middle column scrolls now — the app is pinned to the viewport (`height: 100vh` + `overflow: hidden` on the root in wide mode) so body-level scrolling no longer moves the side panes. Left/right columns keep their existing `overflow-y: auto`, so any overflowing content (e.g. a long planet list) scrolls inside its own track instead.
+- Added `min-height: 0` to the BODY wrapper and the 3-column grid — flex/grid items default to a content-based minimum size, which is what let the page grow past the viewport before.
+- The middle OPERATIONS panel became a flex column with its PanelContent as the scroll area (`flex: 1; min-height: 0; overflow-y: auto`): long tab content scrolls inside the panel while the "OPERATIONS // SHIP COMMAND" header stays pinned — without this, the Panel root's default `overflow: hidden` would have clipped it.
+- Narrow layout (<900px) is unchanged: stacked columns with natural body scroll (the viewport pin applies to wide mode only).
+- e2e: no spec changes needed — none use mouse.wheel/scrollTo, and Playwright scrolls click targets into view within any scroll container. All 15 specs compile unchanged.
+
+## v0.9.2 — 2026-09-29 08:00
+- WORLD MAP (#19): the bottom JUMP ROUTES button list is gone — jumps now happen by clicking galactic chart fields. Systems adjacent to the current one (the same set as before, undiscovered included) are clickable nodes with a pointer cursor and a `// JUMP` sublabel; the current system stays bright green with CURRENT, unreachable systems are dimmed (OFFLINE) and not clickable.
+- NodeGraph (`components/ui/node-graph.tsx`) gained two optional, backward-compatible additions: an `onNodeClick(id)` prop that turns non-disabled nodes into buttons (click + Enter/Space, role=button, aria-label, focusable), and a per-node `disabled` flag — while a jump is in flight every node locks, mirroring the old disabled-button behaviour.
+- The jump flow itself is unchanged: same POST /api/jump call, world state refreshed from the response (turn counter, current system, new routes), event log entry written server-side as before.
+- e2e: two smoke tests touched the removed buttons and were updated — "world map shows…" now asserts the adjacent systems render as clickable chart fields (role=button count matches API adjacency) and "jumping to an adjacent system" clicks the target node by its accessible name. All 15 specs compile; `jumpToFreshSystem` is API-driven and needed no change.
+
+## v0.9.1 — 2026-09-29 06:47
+- UI layout pass (visual only — no game logic or API changes): CARGO HOLD // INVENTORY moved out of the LOCAL SYSTEM tab into a persistent panel in the right column; the UPCOMING ENCOUNTERS placeholder was removed entirely; the SHIP DATA placeholder was merged into VESSEL METRICS.
+- Grid: `260px / 1fr / 240px` → `320px / 1fr / 360px` (left pane ~+23%, right pane ~50% wider).
+- Cargo state wiring follows the existing lifted-state pattern: MissionControl fetches `/api/system` on mount and owns the SystemState; LocalSystemPanel receives it as a prop, keeps its planet list + scan result + explore action, and reports each scan's response up via `onChanged` (same as ShipSystemsPanel) — so CARGO HOLD mirrors scans live with no polling.
+- VESSEL METRICS now carries the two SHIP DATA rows that had real values: SECTOR (current system name from the lifted state) and TURN (`ship.turn`). The rest was dropped — HULL INTEGRITY / REACTOR OUTPUT / CREW ACTIVE duplicate the existing progress bars, TOTAL MODULES duplicates the left column's "N ONLINE" badge, DRIFT VELOCITY has no game equivalent.
+- e2e: no assertion changes needed — the LOCAL SYSTEM tests only assert panel internals (header, EXPLORE buttons, SCAN RESULT) and API state; CARGO HOLD / UPCOMING ENCOUNTERS / SHIP DATA were never referenced by any spec. All 15 specs compile unchanged.
+
+## v0.9.0 — 2026-09-29 02:47
+- EVENT LOG tab — the last of the seven tabs to go live (issue #11): the terminal now renders the save's real game events instead of a placeholder feed. Every action already appends an event row (new game, jump, scan, research, ship upgrade/expand/build, mission accept + completion); this issue adds the read side and the rendering.
+- New endpoint: `GET /api/events` → latest N events, newest first (`{id, turn, type, message, createdAt}`), auto-initializes like all other reads. Optional `?limit=` (default 50, cap 200; non-integers or out-of-range values → 400). OpenAPI spec in code updated (14 → 15 paths) with the Event schema enumerating the eight event types.
+- Read model (`lib/game/events.ts`): `getEvents(db, limit)` — ORDER BY id DESC LIMIT N over the existing append-only events table; `parseEventLimit` for the query param. No schema change — the events table and all its writers already existed.
+- EVENT LOG tab: self-fetching EventLogPanel (MissionPanel pattern — refetches on each tab open). One terminal line per event: `T<turn> // <MESSAGE>` uppercased, with the event's local time as the timestamp; new_game lines render as system lines. Placeholder feed + now() removed from mission-control.tsx.
+- Tests: unit — parseEventLimit default/accept/reject (400) and getEvents newest-first ordering + slicing; writer coverage gaps closed so every action type is asserted with correct turn/type/message (expand had no event assertion at all; build and mission-complete lacked the turn check); e2e — after a jump + scan, both events appear in GET /api/events with the newer one first and the terminal renders both lines (idempotent across retries: asserts on this run's own entries by turn/message, never absolute counts), plus the latest five log lines come back identical (ids included) after the mid-run container restart.
+
+## v0.8.0 — 2026-09-29 01:56
+- MISSIONS tab — contract generation, acceptance and completion (issue #10): the first objective loop on top of issue #9's research. The board is generated deterministically from the save seed; one mission is ACTIVE at a time; completion is checked after every jump and scan and grants its reward into the cargo hold.
+- New table (`lib/db/schema.ts` + DDL): `missions` (id/save_id/type/description/target_system_id/condition_kind/progress_target/progress/reward_kind/reward_qty/state). Seeded on new game AND as backfill step v6 — same pattern as tech; saves created by older code get their board on first read. `SCHEMA_VERSION` 5 → 6.
+- Pure mission model (`lib/game/missions.ts`, no save.ts import — the completion hooks are called FROM save.ts, one-way): three types — DELIVER (jump to a target system), EXPLORE (scan N = 2–4 bodies), FIND (haul in an item of one kind). `missionRng(seed, turn)` anchors generation exactly like world expansion does; every action costs exactly one turn, so the stream never repeats. The board is always topped up to ≥3 AVAILABLE after every action (`topUpMissionBoard`, idempotent); DELIVER targets only discovered non-current systems (none on a fresh game → initial contracts are EXPLORE/FIND).
+- Acceptance & completion: `acceptMission` — 409 while another mission is ACTIVE or the contract isn't AVAILABLE, costs one turn like every other action and writes an event. `checkMissionCompletion` runs inside jumpToSystem/explorePlanet before persist (one atomic write): DELIVER completes on arrival at its target system, EXPLORE counts scans (capped), FIND completes when a haul contains its kind; completion marks DONE, grants the reward as one neutral 'MISSION REWARD' row of the mission's kind (spenders consume by kind only) and writes an event.
+- New endpoints: `GET /api/missions` → `[{id,type,description,targetSystemId,conditionKind,progressTarget,progress,rewardKind,rewardQty,state}]`; `POST /api/missions/{id}/accept` → fresh board (400 non-integer id, 404 unknown, 409 wrong state / active conflict). OpenAPI spec in code updated (12 → 14 paths) with the Mission schema.
+- MISSIONS tab now renders REAL data: one card per contract — type title + state badge (AVAILABLE/ACTIVE/DONE), CONTRACT // #id line, objective, reward line and an EXPLORE-only progress line; ACCEPT is enabled only when the contract is AVAILABLE and nothing else is ACTIVE, each response applied directly (no polling). Placeholder encounter content removed.
+- Tests: unit — deterministic generation per type + reward range over 200 draws, same-stream determinism, DELIVER target selection / null on a fresh game, top-up idempotency + MIN_AVAILABLE floor, v6 backfill on pre-mission saves (idempotent), accept validation (404/409) + turn + event + re-top-up, per-type completion through real jump/explore actions incl. wrong-system non-completion and reward accumulation into one row; e2e — MISSIONS tab accepts a contract via the UI (card flips ACTIVE, button disables), completes it via API (scan loop for EXPLORE/FIND, BFS jump path for DELIVER) and asserts DONE + the reward landed in the hold, plus the mission board survives the mid-run container restart.
+
 ## v0.7.0 — 2026-09-29 00:38
 - SKILL TREE tab — technology research unlocks (issue #9): the second spend-side loop on top of issue #8's ship systems. Researching a tech costs inventory items + a turn and its unlock effect then gates or raises ship actions, so the two tabs interlock: researching WEAPONS SYSTEMS is what makes building WEAPONS possible at all.
 - New table (`lib/db/schema.ts` + DDL): `tech` (id/save_id/slug/name/cost_kind/cost_qty/prerequisites/effect/researched, UNIQUE(save_id,slug)). Definitions are seeded from the pure module on new game AND as backfill step v5 — same pattern as ship_systems; saves created by older code get the tree on first read. `SCHEMA_VERSION` 4 → 5.
