Desktop share images require the configured backend origin

Error message

Desktop share images require the configured backend origin

What it means

Raised by PortfolioService.query_cash_ledger when both date_from and date_to are given and date_from > date_to. Same contract as the trades query: a pre-repository guard, mapped to validation_error, equal dates allowed.

Solutions

1. Swap or reject inverted ranges in the caller before the request
2. Fix the off-by-order bug in the range computation (start = min, end = max)
3. Add a client-side assert so inverted ranges fail fast with a clearer message
4. Add UI validation that disables the query button when from > to

Example fix

# before
svc.query_cash_ledger(date_from=period_end, date_to=period_start)
# after
svc.query_cash_ledger(date_from=min(period_start, period_end), date_to=max(period_start, period_end))

def safe_range(date_from, date_to):
    if date_from and date_to and date_from > date_to:
        date_from, date_to = date_to, date_from
    return date_from, date_to

from datetime import date

def is_valid_date_range(d_from: date | None, d_to: date | None) -> bool:
    return d_from is None or d_to is None or d_from <= d_to

try:
    svc.query_cash_ledger(date_from=f, date_to=t)
except ValueError as exc:
    if "date_from must be <= date_to" in str(exc):
        raise HTTPBadRequest(detail="inverted date range") from exc
    raise

When it happens

Trigger: GET /portfolio/cash-ledger?date_from=2025-12-31&date_to=2025-01-01, or query_cash_ledger(date_from=later, date_to=earlier). Only raises when both bounds are non-None and strictly inverted.

Common situations: Reused date-range widget wired to the cash-ledger endpoint with swapped field names; 'month to date' logic computing start/end backwards after a refactor; manual API testing with hardcoded dates in the wrong order.
