Introduce barbarians as a non-diplomatic civ appended to state.civs,
providing escalating pressure that scales with difficulty and target
civ era. Key mechanics:
- Uprisings spawn on explored tiles, capped by a growing population
limit to keep raids an event rather than a fourth empire
- Era-based pressure curve: raids decay as a civ advances, stopping
entirely at hard-stop techs (industrialization/conscription/railroad)
- Killing hordes summons a Barbarian Leader with an escort; cornering
the lone leader triggers a gold ransom scaled by era and difficulty
- Captured cities are either razed (small) or held inert (large)
- Leader expires after a set lifetime if not ransomed
Diplomacy and AI carefully exclude barbarians to prevent three traps:
shared-enemy attitude pollution, permanent war phase pinning, and
government ladder lockout. Pre-feature saves remain compatible.
New assets: optional civilization-barbarians.png sheet (8 frames).
Updated sprites.md and unit tooltips. Comprehensive verification tests
added in verifyCivilization.js.
- Add aiCitySiteScore to evaluate tiles only outside existing city radii
- Pre-compute covered tiles to avoid overlapping working ranges
- Increase search radius from 7 to 12 for finding distant good sites
- Reject sites within 3 tiles of own cities; soft penalty at 4-5 tiles
- Replace deprecated siteQuality import with new scoring logic
- Add steampunk city sheet asset configuration
- Reassign Victor and other opponents to steampunk city theme
- Enable wheel scrolling on city choices list
- Allow non-combat units (e.g., caravans) to enter enemy cities
- Block movement into enemy cities when at war
Handle 'buildingSold' events to inform players when their buildings are
automatically sold to cover upkeep costs, displaying the building name
and city where the sale occurred.
Replace the four-line text yield breakdown with five icon-based rows that draw
total production as icons and show surplus/loss as a signed group. Hovering any
row reveals exact figures and derived facts like growth/starvation timers.
Replace the comma-separated supported units list with wrapped unit chips that
show each unit individually, including veteran status (gold dot) and upkeep
color coding. Chips display a "+N" overflow marker when units exceed the
visible grid.
Extract citySupport() from cityYields() to compute per-unit upkeep in one pass,
ensuring the Shields/Gold rows and unit chips always agree on costs. Add
describeYieldRow() and describeSupportedUnitTooltip() tooltips for the new
visual elements. Add comprehensive headless tests covering icon run logic,
yield identities, government upkeep rules, and tooltip rendering.
- Add CivilizationCityMap.js: draws the 21-tile fat cross in the city screen
with terrain, specials, city sprite, pips, borders, units, and veiled tiles
- Replace fixed 28-row build list with a scrollable window; add shield cost
and turn-estimate annotations per build choice
- Add garrison display: fortified units shown as clickable roundels

so the city map and main map share identical rendering
- Add cityCentreYield() enforcing the 1-shield/1-trade market-economy floor
- Add cityTileStatus() for consistent worked/idle/taken/offmap classification
- Add describeCityTileTooltip() with terrain title, yield breakdown, missing
improvement explanations, and status line
- Wire improvementSheet and iconSheet paths in civilization-artwork.json
- Add comprehensive verifyCivilization checks for yield notes, centre floor,
tile status, tooltips, and build list capacity
Introduce active diplomacy where rival leaders approach the player with
requests, demands, trades, and gifts rather than passively waiting.
New CivilizationDiplomacy.js module handles:
- 9 request kinds (joinWar, breakTreaty, borderUltimatum, demandGold,
demandTech, techTrade, ceasefire, peace, alliance) with initiative
tiers so urgent calls to arms aren't drowned out by filler offers
- Cooldowns per (leader, target, kind) plus a per-leader gap so a
leader can't spam different requests to bypass rate limits
- Frustration grudge (0-100) raised by refusals, decaying each turn
and dragging attitude toward hostility through the ordinary war path
- Escalation: frustrated leaders demand compensation, then renounce
treaties at breaking point, with ordinary hostility finishing the job
- Border ultimatum promises checked when pledges expire (double penalty
for broken word)
- Unprompted gold/tech gifts from leaders with high attitude
- Staleness validation so requests the world invalidated are dropped
- AI-to-AI requests resolve immediately through the same pipeline
UI changes:
- AI requests queued on state.pendingRequests, presented via audience
popup at the start of the human turn (one per turn, configurable)
- Diplomacy screen shows ACCEPT/REFUSE with consequence hints until
answered; unanswered requests lapse with half-weight penalties
- New event types: treatyRenounced, pledgeBroken/pledgeKept, aiGift
- Leader dialogue for demands, refusals, gifts, and renouncements
- Tetris Attack menu gets a title art backdrop
Data/infra:
- diplomacyRequests tuning in civilization-rules.json (thresholds,
cooldowns, attitude weights, per-request config)
- Frustration, requestCooldown, lastRequestTurn, pledges fields on
civ state — all backward-compatible with old saves
- Full verification suite covering eligibility, resolution, cooldowns,
frustration arc, serialization, and fuzz testing
- Add japanese-themed city sprite sheet (PNG + PSD) and register in artwork config
- Switch several opponents to cyberpunk or japanese city themes
- Fix hut badge stale display by including tile coordinates in hut events and
repainting affected tiles immediately via repaintFromEvents
- Replace diagonal lattice world generation with hash-based jittered grid:
* Shield grassland now uses balanced 2x2 blocks hashed per position to remove
visible screen-space banding while preserving 50% density
* Special resources placed on jittered blocks with adjacency avoidance,
eliminating clumping and barren regions
- Update sprites.md paths and status markers to reflect completed sheets
- Expand verifyCivilization checks for shield density range and special placement
quality (no adjacency, balanced windows, no screen-column alignment)
- Update Tetris Attack dialogue with control instructions and typo fixes
Add new background images for Klaxon, Steve, and Victor characters
with 5 animation states each (r1-r5).

redundant defenders when nothing else is available
- Fix mid-build detection to check build.type before comparing shield progress
- Add City Screen UI for special builds: display gain per turn, color-coded
rows, and tooltips
- Only apply class-switch penalty when switching between unit/building
production types
- Add verification tests for coinage payout, public works remainder carry,
and AI special build fallback
feat(superkart): fix player kart scale + add missing backdrop images
- Compute PLAYER_KART_SCALE from MODE7 parameters instead of hardcoding,
keeping player and AI karts consistent at the camera's follow distance
- Wire up previously null backdrops: volcano, scrapyard, swamp, speedway,
nightcity
Add audio feedback for combat events by introducing unit-specific sound
effects that play during attack animations. Each unit in civilization-rules.json
now has a battleSound property mapping to appropriate audio assets. Adds 10
new MP3 files (arrows, cannon, catapult, gunfire-classic/modern, helicopter,
missile, submarine, sword, tank) and integrates playback in CivilizationMapView's
combat lunge animation.
Lower the minimum distance requirement for establishing trade routes
from 8 to 6 tiles, making caravan routes more accessible. Also refactors
the log message in CivilizationGame to use the TRADE_ROUTE_MIN_DIST
constant instead of a hardcoded value.
- Implement "waste" as corruption's production sibling: distant cities lose
shields to waste (half the corruption decay rate), halved by courthouses.
- Update city yields, UI summaries, and government screen to display waste
alongside corruption and support costs.
- AI now builds courthouses early when combined corruption + waste loss
exceeds 4 per turn, preventing distant cities from becoming useless.
- Refresh building effect tooltips and palace description to reflect waste.

grouped friendly stacks, and enemy effective defense info.
- Preserve portrait emotion animations by reusing when switching leaders.
- Add disembark action to transport unit action menu when carrying units

Allow each opponent to declare their own 2-3 starting technologies in
opponents.json, independent of their civ trait. During game creation,
personal and trait-based starting techs are unioned (deduped) so
pioneering leaders with overlapping lists don't double-grant.
- Add optional setup screen background image (civilization-setup-bg)
- Update leader detail panel description to list personal starting techs
- Deduplicate trait + personal techs via Set in CivilizationLogic
- Add validation for startingTechs arrays, tech existence, 2-3 total count,
and variety across leaders in verifyCivilization
- Add integration tests for personal tech granting and overlap deduplication
Introduce civTraits data structure with 8 traits (scientific, industrious,
commercial, philosophical, zealous, mercantile, pioneering, wealthy) that
provide science/gold/shield multipliers, starting gold, and starting
technologies. Assign each opponent a trait in opponents.json.
- Apply trait bonuses to starting gold and grant starting techs during
game creation in CivilizationLogic
- Route trait multipliers into cityYields for science, gold, and production
- Add a leader detail panel to the setup screen showing name, trait name,
and description, updated live when selecting leaders
- Add validation for civTraits in CivilizationRules (multipliers positive,
starting techs valid, etc.)
- Add verification tests for trait application and city yield multipliers
- Nudge unit sprite position 5px down for better tile alignment
When a city cannot complete a build (e.g., size < 2 for settlers),
shields were accumulating past the build cost, showing confusing
values like "60/40 shields" or negative turn counts.
- Cap shieldBox at buildCost each turn in processCity
- Clamp displayed shields to min(shieldBox, cost) in city screen
- Add tests verifying shield capping and stalled build completion
