`calculate_coast_fire`Compute the Coast FIRE milestone — the capital required today such that, with no further contributions, a portfolio compounds to the user's retirement target by their target age.

`calculate_fire_target`Estimate the savings target needed for Financial Independence / Early Retirement.

`compute_swiss_property_tax`Estimate the Swiss cantonal real-estate capital gains tax (Grundstückgewinnsteuer) for a property sale. Covers all 26 cantons with holding-period adjustments and Ersatzbeschaffung (replacement-residence) deferral. Educational estimate; commune surcharges and value-enhancing-improvement deductions are not modeled.

`get_portfolio_returns`Return RetireCrunch's historical portfolio return profiles for a currency. Each profile is a (return %, volatility %) pair derived from real index data — useful for grounding the assumptions in calculate_fire_target / project_wealth_plan in something defensible rather than guessing.

`get_rebalance_plan`Fetch the rebalancing trades the user decided on in the RetireCrunch Rebalancer, from the plan code they copied ("Send plan to my AI"). Codes work once, for 15 minutes. Returns the trades with IBKR contract ids where known. To act on them, create one IBKR order instruction per trade (create_order_instruction); the user reviews and submits each one inside IBKR. RetireCrunch never places orders.	Fetch the rebalancing trades the user decided on in the RetireCrunch Rebalancer, from the plan code they copied ("Send plan to my AI").

`load_portfolio`Open the user's Interactive Brokers portfolio in the RetireCrunch Portfolio Rebalancer. First call the IBKR connector's get_account_positions, get_account_balances and get_account_summary, then pass their results here UNCHANGED (do not re-type or round numbers). Returns a private link that works once, for 15 minutes — give it to the user exactly as written. No login is needed because the link itself is the key: the positions are encrypted with a key that exists only in the link, and RetireCrunch's server holds just that encrypted copy, which it cannot read, for at most 15 minutes and deletes it when the link is opened. Tell the user this, and that anyone holding the link can open it once, so it should not be shared. RetireCrunch does not recommend instruments or allocations: the user sets their own targets on the page.	Open the user's Interactive Brokers portfolio in the RetireCrunch Portfolio Rebalancer.

`project_wealth_plan`Run RetireCrunch's full year-by-year Wealth Plan projection for a household. Models earned income, pensions, expenses, portfolio growth (accumulating, distributing, or accumulating until a switch year), mortgage amortization, optional property sale, and region-aware tax (US uses 2026 federal+state brackets; other regions use a flat rate). Returns a compact summary with 5-year milestones by default, or the full annual array when yearly_detail=true.	Run RetireCrunch's full year-by-year Wealth Plan projection for a household.

`rebalance_portfolio`Rebalance a multi-currency portfolio: given holdings, per-holding (or per-asset-class) target weights, cash and FX rates, return the exact BUY/SELL trades to reach the targets, the per-currency cash movements (flagging foreign-cash overdrafts), and a summary. It is the same plan the RetireCrunch Portfolio Rebalancer page makes: class goals drive holdings (locked holdings stay put, target_mode "custom" holdings keep their target_pct, the rest share the class goal pro-rata to value), with an optional buy-only mode, tolerance band and new money. The verdict says why there are trades or none (onTarget, locked, belowMinimum, …). Planning math only — no transaction costs or taxes.
