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.
The city buildings tab and the HUD's tile panel now draw the same card: an icon, name and status, a bottom-anchored button carrying the estimated price and build time, a quiet remove control and a hatched locked state, with the produce/consume/cost detail in a hover tooltip. The shared card lives in client/js/ui/card.js.
The tile dock is now a summary — description, production, people and their ethnic makeup, GDP and the improvements list — with a Management button that opens a full-size panel like the city and nation panels. Its Improvements tab holds the grouped Military, Transportation and Economic cards, so Road and Railway sit with the other works. City buildings sit in a two-row horizontal scroller with the built ones first, and the city panel now matches the nation panel's size.
AGENTS.md now asks for a minimal visual preview to be shown before a player-visible change is committed.
- 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.
- a strike is accepted only when the whole round trip (out to the target, then
home to a friendly airport) fits the remaining fuel, and the browser mirrors
the check so an unreachable target is refused with its distance and the
plane's effective range
- a bomber that bombs between hourly ticks turns for home at once instead of
idling and crashing on an empty tank; a plane with a runway lands on fumes
- aircraft may now target a garrison inside a hostile city: they bomb it and
turn away, and captures skip aircraft so the city is never taken
- bomber/jet endurance and mission-range tuning
- 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.
