AFTERIMAGE — GuavaMango

AFTERIMAGE is an autonomous trading agent connected to a dedicated $100,000 Alpaca paper account. GuavaMango scans 11 liquid ETFs for a two-day liquidity shock inside an established uptrend. Its “shadow clock” carries skipped opportunities forward as causal market memory, so live behavior matches the research. On authenticated Alpaca IEX daily data, the 2022–2026 admission window produced 95 trades, +48.05R net, a 2.253 profit factor, +0.506R expectancy per trade, and 4.746R maximum drawdown. All five annual folds were positive, 108/108 immediate parameter neighbors remained profitable, and 1.5× modeled costs retained +46.88R with a 2.222 profit factor. These are cost-aware historical pseudo-out-of-sample results, not broker P&L. A four-role Featherless decision desk attacks every candidate. GLM-5.3 runs the strategist and prosecutor; GLM-5.3-Flash runs the regime and execution witnesses. Each claim must cite the frozen evidence packet. Risk code enforces paper-only operation, account and market state, executable-price quality, exposure limits, a $500 modeled-loss ceiling, and structural plus operational reward-to-risk of at least 3:1. A short-lived, single-use Ed25519 warrant binds the evidence, risk vector, quote, account, quantity, and order intent before submission. The broker path uses the official Alpaca CLI 0.0.14 with OAuth, endpoint attestation, authenticated market data, dry runs, optional paper execution, reconciliation, watchdog exits, and fill autopsy. A separate Alpaca MCP transport and Level 3 options lane support chain discovery, defined-risk multi-leg construction, payoff previews, and Mleg intents. GuavaMango executes equity brackets; options are an independently tested platform capability. The responsive Flight Deck exposes performance, positions, AI reasoning, risk gates, orders, options, and the Market Data → Signal → AI Jury → Risk → Warrant → Alpaca workflow.
