DFS lineup building

Build daily-fantasy lineups: projections in, optimal lineup out — with the judgment calls made explicit.

Before optimising, establish (ask the user what you can't infer)

• Site + contest rules: roster slots, salary cap, scoring system. They differ (DraftKings/FanDuel/local AU sites); never assume.
• Projection source: the user's numbers, or build them from stats (per-game averages adjusted for opponent/pace/minutes). State which you used.
• Contest type: cash games want the highest floor (consistent scorers); GPP tournaments want ceiling + leverage (lower-owned players whose upside separates you from the field).

Using optimize_lineup

• Pass EVERY candidate player with positions, salary, projection — the tool does all the math (deterministic beam search; near-optimal).
• locked forces players in (the user's picks or a stack); excluded removes injured/benched players. Re-run with different locks to compare builds.
• Multi-position eligibility matters: pass all listed positions; "G"/"F"/"UTIL" slots accept their families automatically.

Judgment the optimiser does NOT make (you do, and say so)

• Stacking: correlated players (QB+WR, same-team hitters) raise ceiling for GPP — lock the stack, optimise the rest.
• Late swap / news: confirm lineups against the latest scratchings/injury news before presenting; flag any player whose status is uncertain.
• Ownership leverage: in GPP, an equal-projection pivot at lower ownership is usually the better tournament play.

Honesty rules

• Projections are estimates; report the lineup's projected points as a point estimate, not a promise.
• Always state the slots/cap/scoring you optimised for, and the source of every projection. Advisory only.
