Analyze exported listings

Flipper reads user-provided JSON; it is not a crawler. The default pipeline collects the feed, deduplicates seen IDs, parses secondhand-PC components, optionally enriches uncertain text, estimates value, scores opportunities, and optionally sends alerts.

python main.py --feed data/listings.json

Deterministic parsing and heuristic pricing remain usable without network services. Asking price is the seller's request. Ideal buy and resale values are estimates, not acquisition cost or realized proceeds. Market-data observations are active asking prices rather than evidence of completed sales.

Use --no-ai, --no-market, or --no-alert to disable optional stages. Run python main.py --help for the authoritative option list. A normal analysis never creates inventory; use the explicit acquisition workflow after a purchase decision.

For explicit source-neutral inputs, python main.py deals analyze --help calculates exact expected economics without persistence. See Generalized deal intelligence for unknown-value, ROI, velocity, evidence, and comparison semantics.
