 # Changelog
 ## v0.9.9 — 2026-09-29 11:21
 - The WORLD MAP chart is now a force-directed graph (d3-force) with pan + zoom (d3-zoom), replacing the hand-rolled static NodeGraph render (#28): nodes settle into a dynamic layout seeded from the API coordinates and visibly rearrange after every jump, then auto zoom-to-fit so the whole network stays framed in the chart box. Wheel/drag pans and zooms the scene; only systems adjacent to the current one remain clickable (same `role=button` + name contract as before), all nodes lock while a jump is in flight, and a real pan's trailing click never triggers an accidental jump. Jump flow (`POST /api/jump`, turn counter, `onJumped` refresh from #30) is unchanged; the now-orphaned hand-rolled `NodeGraph` component (world map was its only consumer) is deleted.
 ## v0.9.8 — 2026-09-29 10:20
 - The OPERATIONS tab bar now stays pinned while its content scrolls (#31): the TabsList is `position: sticky; top: 0` with a z-index above the panel content, so it pins to the top of the OPERATIONS scroll area in wide mode (where only the center pane scrolls, #21) and to the viewport when the body scrolls in narrow mode. Its existing opaque background (`--surface-raised`) keeps scrolled content from showing through; no layout restructure needed — #21 behavior is untouched.
 - e2e: new smoke spec — shrink the viewport so WORLD MAP's fixed-height chart overflows the pane, scroll the panel to the bottom (asserting a real offset), and check the tablist's bounding box hasn't moved.
 ## v0.9.7 — 2026-09-29 09:59
 - LOCAL SYSTEM no longer shows the previous system after a jump (#30): WorldMapPanel owns the world state and applied the `/api/jump` response locally, so MissionControl's lifted `/api/system` state (which drives the LOCAL SYSTEM tab, CARGO HOLD and the SECTOR row) went stale until a page refresh. The panel now takes an `onJumped` callback that MissionControl wires to a `/api/system` refetch after every successful jump — same failure policy as the mount fetch (keep old state on error).
 - e2e: new smoke spec — click-to-jump on WORLD MAP, wait for the chart's turn counter to update, switch to LOCAL SYSTEM and assert its header shows the NEW current system from `/api/world` (no `page.reload()` workaround; one jump per run/retry, same pattern as the existing jump test).
 ## v0.9.6 — 2026-09-29 09:41
 - The active operations tab now survives a page refresh (#27): the selected tab ID is persisted to `localStorage` (`sw-active-tab`) on every change and restored on mount when it matches one of the seven valid tab IDs (unknown/stale values fall back to WORLD MAP). The Radix Tabs are controlled for this; SSR and first client render still agree on the default, so there is no hydration mismatch.
 - e2e: new smoke spec — click CREW, reload, assert `aria-selected=true` again (fresh context per run/retry, no API state touched, idempotent).
 ## v0.9.5 — 2026-09-29 09:13
 - Fixed the production freeze reported after the v0.9.3 (#21) deploy ("entire UI system is now fucked"). Root cause was NOT the #21 layout change (verified healthy across all 7 tabs and multiple viewports — no clipping, middle pane scrolls internally, side panes fixed): it was world name generation. `makeName` draws from a finite pool of 16×8=128 system names with an unbounded rejection loop, so once a save grew past ~128 systems (turns of play / e2e jump loops), any jump into an undiscovered system spun forever on Node's single thread — sql.js runs synchronously, so the whole process blocked and EVERY API route hung, leaving all panels stuck at LOADING.
 - `makeName` (lib/game/world.ts) now falls back to numbered variants (`Kepler Drift 2`) once the pool is exhausted, so it always terminates; `makeCrewName` (lib/game/crew.ts) gets the same guard — the roster has no cap and its 16×22=352 pool would eventually exhaust too.
 - Tests: unit — both name generators terminate with unique numbered names after full pool exhaustion (80 tests green, was 78); e2e unchanged — no spec depends on the old behavior and a fresh CI stack never approaches 128 systems.
 ## 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.

kamilkrzywda	1710e50b63	fix(ui): pin the OPERATIONS tab bar while panel content scrolls (#31 ) CI / build + unit + e2e (pull_request) Successful in 2m47s Details The TabsList is now position:sticky top:0 with a z-index above the panel content. In wide mode it pins to the top of the OPERATIONS scroll area (#21's center-pane scroller); in narrow mode, where the body scrolls and there is no inner scroll container, it pins to the viewport. The existing opaque background keeps scrolled content from showing through.	2026-09-29 10:22:14 +00:00

kamilkrzywda	e27ff7015e	fix(ui): refresh LOCAL SYSTEM after a jump instead of waiting for a page reload (#30 ) CI / build + unit + e2e (pull_request) Successful in 2m39s Details WorldMapPanel owns the world state and applied the /api/jump response locally, so MissionControl's lifted /api/system state (LOCAL SYSTEM tab, CARGO HOLD, SECTOR row) stayed on the previous system until a full refresh. The panel now takes an onJumped callback that MissionControl wires to an /api/system refetch after every successful jump.	2026-09-29 10:00:18 +00:00

kamilkrzywda	f4690bc1a2	feat(ui): keep the active operations tab across page refreshes (#27 ) CI / build + unit + e2e (pull_request) Successful in 2m15s Details Persist the selected tab ID to localStorage (sw-active-tab) on every change and restore it on mount when it matches one of the seven valid tab IDs. The Radix Tabs become controlled for this; SSR and first client render still agree on the default, so there is no hydration mismatch.	2026-09-29 09:42:18 +00:00

kamilkrzywda	06f8a28e96	fix(game): numbered name fallback when pool exhausted — server no longer freezes past 128 systems CI / build + unit + e2e (pull_request) Successful in 2m38s Details Production freeze reported after the v0.9.3 (#21) deploy: every API route hung and all panels stayed at LOADING. Root cause was not the #21 layout (verified healthy across all 7 tabs/viewports) but makeName's unbounded rejection loop over a finite 16x8=128 system-name pool — once a save grew past ~128 systems, any jump into an undiscovered system spun forever on Node's single thread (sql.js is synchronous), blocking the whole process. makeName and makeCrewName now fall back to numbered variants ('Kepler Drift 2') once their pools are exhausted, so they always terminate.	2026-09-29 09:18:00 +00:00

kamilkrzywda	d2fb252a98	feat(ui): only the middle column scrolls — side panes stay fixed (#21 ) 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.	2026-09-29 08:21:14 +00:00

kamilkrzywda	ef1d282770	feat(ui): world map — jump by clicking chart fields (#19 ) Remove the bottom JUMP ROUTES button list; systems adjacent to the current one become clickable galactic-chart nodes (same POST /api/jump flow, same state refreshes). Current + unreachable systems are dimmed and not clickable. NodeGraph gains optional onNodeClick + per-node disabled (backward-compatible); two smoke tests updated to click chart fields.	2026-09-29 08:00:44 +00:00

kamilkrzywda	b05ac32da6	release v0.9.1 CI / build + unit + e2e (pull_request) Successful in 2m37s Details	2026-09-29 06:48:20 +00:00
kamilkrzywda	85627201f8	feat(ui): layout pass — CARGO HOLD to right column, wider panes, drop placeholders CARGO HOLD // INVENTORY moves out of the LOCAL SYSTEM tab into a persistent right-column panel; UPCOMING ENCOUNTERS removed; SHIP DATA folded into VESSEL METRICS (SECTOR + TURN kept with real values, filler dropped). Grid goes 260px/1fr/240px -> 320px/1fr/360px. Cargo state uses the lifted-state pattern: MissionControl owns /api/system and LocalSystemPanel reports each scan's response up via onChanged (ShipSystemsPanel style) — no polling.	2026-09-29 06:48:20 +00:00
kamilkrzywda	fb11a8ef81	Merge pull request 'v0.9.0 — EVENT LOG: real game events in the terminal (#11 )' (#18 ) from event-log into master CI / build + unit + e2e (push) Successful in 2m51s Details	2026-09-29 05:05:30 +02:00
kamilkrzywda	37b193ffb8	test(e2e): tab-switch test — assert real log lines, not the removed placeholder CI / build + unit + e2e (pull_request) Successful in 2m36s Details CI run 361: v0.9.0 replaced the placeholder feed with EventLogPanel, but this pre-existing assertion still expected 'SHIP LOG // PLACEHOLDER FEED'. Assert a real T<turn> // <MESSAGE> line instead — every save has the turn-0 new_game event, so it holds on a fresh stack and across retries.	2026-09-29 03:02:04 +00:00
kamilkrzywda	760a45fc4b	release v0.9.0 CI / build + unit + e2e (pull_request) Failing after 3m12s Details	2026-09-29 02:48:25 +00:00
kamilkrzywda	0b435a583b	test(e2e): event log entries + restart persistence smoke: jump (shared helper) + scan, then assert both events are in GET /api/events with the newer one first, and that the EVENT LOG terminal renders both T<turn> // <MESSAGE> lines. Idempotent across retries — asserts on this run's own entries by turn/message, never absolute counts. state: the latest five log lines come back identical (ids included) after the mid-run container restart.	2026-09-29 02:47:36 +00:00
kamilkrzywda	29e8ac6909	feat(ui): EVENT LOG tab renders the real game log Self-fetching EventLogPanel (MissionPanel pattern — refetches on each tab open). One terminal line per event: T<turn> // <MESSAGE>, newest first, with the event's local time as the timestamp; new_game lines render as system lines. Placeholder feed + now() removed from mission-control.	2026-09-29 02:45:38 +00:00
kamilkrzywda	21abf8768f	feat(api): GET /api/events endpoint + OpenAPI Latest game events, newest first; auto-initializes like the other reads. ?limit= defaults to 50 (cap 200), non-integer/out-of-range → 400. OpenAPI spec gains the path + Event schema (14 -> 15 paths).	2026-09-29 02:45:38 +00:00
kamilkrzywda	8d678d73ce	test: assert events for the remaining action types expand had no event assertion at all; build and mission-complete asserted type/message but not the event's turn. Issue #11 requires every action type to be covered with correct turn/type/message.	2026-09-29 02:45:38 +00:00
kamilkrzywda	0d5858695a	feat(events): event log read — getEvents + limit parsing lib/game/events.ts: the latest N events of the save, newest first (ORDER BY id DESC), with parseEventLimit for the optional ?limit= param (default 50, cap 200, 400 otherwise). Unit tests cover default/accept/reject and newest-first ordering + slicing.	2026-09-29 02:45:38 +00:00
