    "subject": "Gave the world a simple economy: one pool per nation and a global market",
    "body": "The simple economy is now the default and the old simulation is frozen as the hard model, selectable per game. A nation keeps one resource pool available in every region, fed by public production works rather than private per-region stores, and construction and training begin at once, paced by the region's spare power instead of gathering materials over days.\n\nMoney is euro only: a per-inhabitant daily tax funds a treasury spent in a global market, where buy and sell lots trade against the world stock and move its price. The hard economy keeps its per-nation currencies, central banks and exchange rates.\n\nSimple games skip the price-settling warmup and economic migration; the snapshot carries the economy model, the market and the pool figures the client draws. Added the matching test suites and the design briefs under docs/simple_economy."

    "body": "Unit orders now gather steel and high-tech over the days before training, exactly as buildings do, and clicking a queued order reveals what it is gathering, its reserved budget and the soldiers it will draw.\n\nThe trade graph cached a producer-less node list under a stamp that already reflected the producers' stores, so every seeded mine stayed invisible to buyers and rare-good prices settled at a huge multiple of base; the storage nodes are now re-read after production.\n\nMoney gifts draw the giver's central-bank reserves in the denomination first, buy the rest from the issuing bank at the market rate, convert into the receiver's currency, and cannot buy from a bank their nation is at war with.\n\nPruned the finished design briefs (intelligence, stacks, air movement, politics performance, economy balance, training UI and FIXME) and refreshed the index and cross-references."

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

    "subject": "Stopped a tile-work rebuild from discarding every cached trade walk",
    "body": "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.\n\nThe 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.\n\nTogether 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."
