The server sent the whole army on every snapshot and the client re-cloned
the whole icon layer whenever a unit moved, so a settled world with a
standing army drained the broadcast loop and the frame loop alike.
- Ship only the units and city list that changed, keyed by a per-peer
fingerprint and a serialised hash, and merge those deltas on the client.
- Memoise the battlefield scan on a battle version bumped when a unit
joins, leaves or changes side.
- Skip the DOM writes for units whose snapshot object is unchanged, and
cache the unit-view inner nodes.
- Fold units, cities and tile markers onto the nearest world copy instead
of mirroring the icon layers, which re-cloned thousands of views every
frame; the small decoration layers still mirror, and only on a change.
Frame work at full zoom-out with units moving fell from ~190ms to ~6.5ms.
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.
- 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.
