PINK: E2E trace analysis — Pass 9 contracts/events/network/FFI/diffs (L1-L16)
Ninth pass: VenueEvent.price=0 causes 100% PnL loss (L3), available_margin set to wrong field in user stream (L4), wallet_balance defaults to 0 (L5), 14+ bugs fixed between backup and current code (L12), real pipeline never tested by any test function (L13), no proxy support (L9), 5-min DNS cache (L10). Backup diff reveals the current Rust kernel has ~14 bugs fixed vs the backup version. 16 new flaws, 215 total. Co-authored-by: CommandCodeBot <noreply@commandcode.ai>

"""PINK DITAv2 Canary — gated pre-cutover validation.
|
||||
|
||||
Two rounds on VST with the full PinkDirectRuntime wired (WS stream active):
|
||||
|
||||
Round 1 XRP-USDT LONG 4 XRP ≈ $5 notional 5× leverage
|
||||
Round 2 ADA-USDT SHORT 140 ADA ≈ $8 notional 4× leverage
|
||||
|
||||
Each round asserts:
|
||||
C1 WS stream started (event_seq > 0 after connect)
|
||||
C2 available_capital == e_available_margin (E rules)
|
||||
C3 reconcile_status OK or WARN throughout
|
||||
C4 After fill: event_seq advanced (WS or gap-backfill delivered events)
|
||||
C5 k_capital finite and > 0 at all checkpoints
|
||||
C6 Position flat after EXIT (exchange confirms no open position)
|
||||
C7 Final k_capital within ±10 USDT of seed (normal P&L band for tiny notional)
