TopstepX never reports the Maximum Loss Limit, but it's deterministic:
floor = min(0, eodBalanceHigh − trailingDrawdown), locking at the $0
starting balance. The EOD curve rebuilds from daily P&L + fund events,
with off-book fee drift spread across days proportionally to reported
fees (validated against a platform-reported MLL to ~$0.10). Stored in
autoLiqThresholds — negative, or +$0.01 once locked — so dead detection,
dashboards, and the ruin model's startThreshold all use the real room.
Guards move from '> 0' to '!== 0'; 0 still means no floor. canTrade=false
accounts are skipped. daily_pnl gains a fees column for the weighting.

@microsoft/signalr does an unconditional require('ws')/require('eventsource')
when constructing a connection; bundled (turbopack) builds throw 'dynamic
usage of require is not supported', which the login chain mislabelled as a
login failure and retried every 60s. Externalize the package and never let
hub setup fail the login — REST polling covers everything the hub does.

- TopstepXClient (ProjectX Gateway): API-key auth, SignalR user hub,
Trade/search daily P&L, emulated OCO exits, books-invariant
withdrawal detection for $0-start accounts
- Platform-aware client pool, credentials (api_key column), and
credential form; $0-size account types match by prefix alone
- Drain stages: min-day ($5-$15 randomized) MNQ legs for the
configured days, then wait for the 50% withdrawal; stage pills
show 'Stage N – Drain'
- Account calendar projects the perfect path: future days book their
planned targets, simulated 50% withdrawals, payout marker
