Single-file static HTML canvas demo (lab/index.html, 1212 lines) walking
through the meridian autonomous RWA market-making agent in eight scenes:
1. Oracle waterfall Chainlink + rates + custodian feeds
arrive with confidence + freshness
2. Fair value & spread Weighted-average fair value; spread by
geography (US 5 bps, EM 30 bps, Restricted
closed). Uses the real _geography_adjustment
table from rwa_market_maker.py.
3. Quotes go out Bid/ask posted to maker venue,
geography-gated (Restricted gets null)
4. Fill arrives Taker hits the US bid; pool inventory
shifts; mid-price updates
5. Inventory rebalance RWA inventory drifts +12%; agent routes
through resolver to bring back to target
6. Idle yield park Idle CR8-USD float → Lucidly syUSD
7. Circuit breaker MeridianVault.setCircuitBreaker(true) on
oracle staleness or 3-sigma divergence —
uses the real on-chain function
8. End-of-cycle report P&L per geography, fills, inventory delta,
yield earned
Palette flipped from Mixdown: cyan primary, gold secondary; cool slate
gradient vs Mixdown's warm amber. Restricted-zone elements rendered in
'hot' red. CSS-var names unchanged so the engine code is byte-identical
to Mixdown — just swapped values.
New visual primitives:
- drawGeoLanes() horizontal banded US/EM/Restricted underlay
- oracle agent type (diamond/purple) — Chainlink/rates/custodian
- lucidly agent type (green circle) — syUSD destination
Real meridian-repo references woven in:
- OracleAdapter, StrategyExecutor, RiskManager (actual module names)
- MeridianVault.setCircuitBreaker(bool) (actual on-chain function)
- rwa_market_maker.py _geography_adjustment table values
Companion lab/SCENES.md (109 lines) documents the scene contract for
