The trade graph's cache stamp mixed in the tile-improvement version, which a mine, mill or plant rebuilt in place bumps many times a day, so every city's sea-lane flood was thrown away and rebuilt. The stamp now keys on the transport network, the territory and the storage-node set alone: over ten days the rebuilds fall from hundreds to the 45 the world needs, and the daily resource tick from about 700 ms to about 150 ms.
The snapshot path is memoised against the counters that actually move it -- the per-civ headline population and GDP, the per-city building and per-nation government/research modifiers, the port and food bonuses, the road and railway tile counts and the ethnic make-up rebuild only when their version changes; the flattened visible set is cached alongside explored; and the HUD upkeep sums without building the labelled budget breakdown. DELTA_COLLECTIONS had drifted from the snapshot's key names (it listed gdpBaseline while the state ships productionBaseline, and tileEthnicity while the version is ethnicity), so the static baseline was re-sent as JSON on every broadcast; the collection/version pairs are now explicit.
Together a broadcast falls from roughly 60 ms to 18 ms and the bytes for fifty of them from 57 MB to 24 MB, and 200 in-game hours simulate in about a third of the time. regionTiles caches the per-city owned lists behind the daily economy walks, and supplier reserves read a region's headcount without deriving its GDP; getCityEconomy itself stays uncached outside a snapshot so a simulation read still reflects a direct population edit at once.
- The monthly budget breaks each expense into the resource bought, its quantity and the average price paid: tile improvements already did, and now every upkeep row (buildings, units, works, transport) does too.
- Private producers settle their daily wear from their own cash and borrow the shortfall from the central bank, so their cash never goes negative.
- Producers fund their own construction and upgrades on the same credit; the treasury pays only for public works, roads and railways, and no private purchase is filed as a public tile-improvement expense.
- The server settles the world until every commodity holds within 10% over a trailing seven days instead of a fixed 150, capped by --warmup (0 skips it).
- The shipped month report carries its label again, so the budget header and pager name the month.
Food, steel, luxury and high-tech now share one flat month-long reserve. A region keeps bidding for the shortfall while its store is thin, so a war that empties a pantry refills it from the grid instead of starving; the harvest is served before the city load, unmet food bids the price up, the army's rations count as demand, and a converter that cannot cover its power bill idles instead of making a loss.
The delivery graph walks sea lanes any distance, so its walks are cached across days behind a road/railway/work/territory stamp and only dropped by a wartime unit move. Units are indexed per tile, market access and node populations are memoised for the day, and the server can settle a fresh world before serving (--warmup, 150 days by default).
Roadmap records the remaining follow-ups -- the politics/migration hot path and the luxury/high-tech price plateau -- and that freight's heavy energy draw is intended.
Every road, railway and tile work now rises as an economic construction site instead of a queue entry. A site gathers its materials over days from reachable regions, refusing any supplier quoting above the price it was budgeted at (a 1% tolerance); a day that buys nothing stalls the site, raising a red mark and letting the nation raise the budget to current prices or cancel it. The upfront budget covers the build cost plus the market value of its steel and high-tech, energy stays a grid draw, and any money left over stays with the finished work as a maintenance reserve.
That reserve now pays the work's own daily steel and high-tech wear before the treasury is billed, so a well funded work spares the state until it runs dry; the spent money is paid into the nation's regions. Building upgrades run through the same gather-build-maintain machinery, sharing the site's kind flag and target level. The legacy tile-work queue and the market building are gone.
Bundles the in-progress chart sizing for the central bank panel.
World generation now aims at a fixed share of the ice-free tiles (60%) instead of a minimum continent count, bisecting the water level for it rather than sweeping every step, and still joins the ocean into one body. Ice and tundra are the outermost rows only, scaled down on small maps so the fixtures keep usable land.
Cities score their site, coastal plains best and landlocked worst, avoiding tundra and desert. Every nation that holds a coast gets a port city on each island it owns, and any landmass left empty is settled by the nearest nation, so no land starts unowned. A coastal city opens with a port already built.
Bundles the in-progress work in the tree: the commodity monthly price series and inflation the central bank's chart reads, and the rolling city-to-city migration graph the population map draws as flow arrows.
- Five resources (energy, steel, food, luxury, high-tech) with per-city stores, a world market, delivery and material upkeep.
- Resource-producing tile works built outside cities; every nation opens with the works its economy needs.
- Real game-icons.net art replacing the dummy icons for the new resources and works, with the credits updated.
- Political map country names were invisible because the label SVG had a zero-sized viewport, which some browsers never paint; size it to the world and guard it with a test.
- Added a Devlog button showing the ten latest commits, generated into client/js/devlog_data.js by scripts/generate-devlog.js and refreshed by the pre-commit hook.
- Worked through FIXME.md: the city button and a unit double-click now open the city, and the stat tooltip escapes the HUD so the unit panel cannot cover it.
- The server creates its game at startup and clients only join it; the Create game screen and the configure_game path are gone, and testing is a --testing server flag.
- A page on a loopback host signs in as adrien, claims France and gets the free, instant testing buttons, while the server grants free orders only to a loopback socket whose Origin is also loopback.
GDP per capita had no natural growth, so a nation's economy only moved
when population, buildings or war did. The summary stats also offered
inconsistent hover text: a native browser tooltip for popularity and none
at all for the budget.
- Every land tile now gains a constant 0.01% of the GDP per capita it
opened with, once a day. Because the amount is fixed the relative growth
rate tapers over the years. Each tile's opening figure is snapshotted
once and shipped to the browser, so the tile panel and the GDP-per-capita
map mode stay in step with the server.
- The population, GDP and GDP/capita tooltips show the relative growth:
against 1 January 2000 through the first year, then year on year. The
monthly captures now keep a rolling thirteen months for the baseline.
- Every summary stat explains itself through the same custom bubble.
Popularity's native title moved onto it, and Budget forecasts the next
calendar month at the current hourly net, as a compact figure such as
"+€3.28B/mo" (hoursInNextMonth follows the real calendar).
- The tile GDP breakdown shows gains with a plus sign (natural growth,
ports) rather than the old minus.
Added tests for the constant daily gain, the falling relative rate, the
first-year and year-on-year baselines, the snapshot baseline, the budget
forecast and the calendar month length.
- The bombardment overlay was rebuilt every animation frame, and each barrage
scanned the whole army to find its target (O(strikes x units)). It now
redraws at most at the renderer's 24 fps, reuses its SVG/DOM nodes, and
resolves garrisons from one per-snapshot tile index, so a high-refresh
display no longer makes a big battle worse.
- Route truncation had the same shape: every step of every route rescanned
every unit. The snapshot now buckets the army by tile once.
- Idle units no longer have identical left/top rewritten every frame, and the
whole-map fog buffer is rebuilt less often.
- Snapshot traffic: cityStats and visible are delta-encoded like territory and
population, city stats carry a content-hash version, tile ethnicity is
memoised, and a city's economy is derived once per broadcast instead of
twice. A per-peer civ change now forces a full snapshot, since the visible
set is per-viewer.
- Tile improvements (fortifications, radar towers, coastal cannons), trenches,
zone of control, support-unit capture and launch transports, with parabolic
barrage arcs drawn between attacker and target.
- Focused research that pours points straight into the chosen technology, with
per-technology progress kept when the focus changes, plus repeatable levels.
- Popularity reworked to integer points, war and pillage effects, minority
policies and month-over-month arrows on the nation summary.
- City progress bars, square improvement buttons, a technology tab of wide
short cards with progress bars, transport cargo readout and double-click to
open a city panel.
- aircraft attack orders fly a sortie to the target, bomb once, return to a
friendly airport and re-arm (two-day cooldown, charged per aircraft); rebasing
is bounded by fuel rather than the 10-tile combat radius
- artillery and warships open a sustained hourly bombardment on a standing
target, drawn as a red dashed line and ring while either endpoint is selected
- a game launched from localhost can enable a testing mode whose train and build
rows offer free, instant orders; the server only honours them for a loopback
admin in a testing game
- an open city panel now unlocks aircraft as soon as an airport finishes
Roads are pre-generated between cities with a greedy geometric spanner and flatten unit movement cost. City improvements now only affect the tiles their region controls, with per-region tax collection and a Cities tab. The budget is a grouped, scrollable table with 25%/year tax and a 10%-of-GDP opening treasury. Also merged the tile info into the city panel, kept conflict and budget expansion state across snapshots, added join notifications, filled border corners, drew battle sides as stacks and made tab overflow scroll.
