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.
Production buildings are now independent private-sector agents: they keep what their output sells for, run only to the demand they can actually sell, and spend that cash on steel and high-tech upgrades when their demand grows. Grid power is a paid private flow between plants and their consumers, and regions synthesise the food their own harvest and the reachable market cannot supply.
Island regions no longer famine: a region with no reachable supplier grows its whole shortfall from energy, and grid power now feeds cities and food before the converters, so a famine never waits on a factory.
Bundles the in-progress tree cleanup that was already present in the working tree.
- Each nation has a currency and each region a private-sector cash basket, borrowing from its central bank at the bank's rate; the government may always pay, going into central-bank debt when its budget runs red.
- Resources are bought from reachable stores only: the region itself first, then same-nation regions, then foreign ones, paid for out of private cash or, for government orders, the treasury. Drawn national stores are paid to their owning region.
- A grid in deficit imports power from a reachable surplus grid instead of a market fallback; downgrading a building no longer refunds anything.
- The monthly budget lists each resource's economic value, expands to a resource-to-source tree and keeps a cash figure beside it.
- Regions report what their people went short of over the day; starved research buildings and power-starved works raise a private daily notice.
- The city panel gains a Resources tab: reserves per resource, their market value and the private sector's daily consumption.
- 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.
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 catalogue had grown a barracks, wartime shelters, an air-defense
battery, a warm-water port and a shipyard, but only as data: infantry
still trained without a barracks, shelters did nothing, and an airport was
just an airbase. Each building now names the rule it grants with a
`mechanic` id, so the simulation and the city panel describe the same
thing without magic strings.
- Barracks and shipyards open one more production line each. A line sticks
to one entry at full rate, so two units build at once rather than the
head absorbing every line; the base behaviour (one queue, overflow
carrying into the next entry) is unchanged.
- Wartime shelters keep 10% of civilians per level safe from bombardment
and are very hard to knock down, and ranged fire can now destroy a
building level outright, with no refund. Each building rolls its own
chance per point of damage, from a generator seeded off the world so a
bombardment replays identically.
- Air defense fires one volley at a hostile aircraft the moment it enters
the city tile, scaled by its level; a plane shot down never drops its
bombs.
- A port adds 1000 GDP per capita per level, per adjacent sea tile, to
every tile in its region.
- An airport draws a daily trickle of people from every other airport city
in the world, scaled by the destination's level.
- Wired the new effects into the city panel and taught the repeatable
Industrial Automation to satisfy other technologies' prerequisites.
Added tests for each mechanic and for the parallel lines.
- 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.
- the nation summary shows own-government approval, white in the neutral 40-60% band, red below and green above
- the city and government panels keep a fixed size per tab, dock below the summary and no longer cover it, and their tab bar wraps instead of being clipped
- propaganda campaigns grow exponentially harder near their opinion ceiling or floor, so the last percent are the hardest to win
- memoised city, nation and matrix approval against the politics version, invalidated by territory redraws, so snapshots stop recomputing it every frame
- extracted the duplicated modal tab wiring into modals/tabs.js
- tests: campaign-difficulty, approval-colour and cache-invalidation cases (513 pass)
- 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
- run_tests.js discovers and runs each *_test.js in its own worker process
(--jobs N to cap the pool, --file <name> for a single suite)
- GameState caches the deterministic terrain, city sites and road network by
(seed, mapConfig, civ count), rebuilding only the mutable per-game state
- the snapshot ships mapConfig and the client rebuilds terrain from it, so the
DOM tests can use the small map fixture and a non-default config renders right
- shortestPaths can stop once every target city is settled
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.
