Automated, parametrized scenario battery driving the REAL PINK runtime
(policy->intent->PinkDirectRuntime->kernel->BingX VST->persistence) via crafted
snapshots, asserting 6 capital invariants per scenario: (1) per-fill Δcapital ==
realized; (2) end Δcapital == Σ per-fill realized (cumulative across cycles, since
slot.realized resets on ENTER); (3) exchange flat + no orders (signed); (4)
persistence parity (trade_events/account_events/trade_exit_legs vs kernel); (5)
notional ≤ capital×max_leverage; (6) guard correctness.
Controlled testnet: flat-start, single scenarios, reliable kernel close-all
pre-flatten (no cross-scenario cascade), ~$20 sizes, no autonomous loop, BLUE
untouched. Gated +PINK_CAPITAL_HARNESS.
Live VST result: 6 passed + 1 xfail.
- round_trip, sequential (multi-cycle continuity), exit_then_reentry, and 3 guard
paths (suppressed nonfinite-capital / sub-floor price, degenerate-snapshot HOLD)
all GREEN — capital accounting verified for the single-leg/sequential PINK paths.
- multi_leg XFAIL (documented): multi-leg partial reduce-only exits leave a lot-step
rounding residual on the venue (kernel believes flat, exchange has a remainder) —
a real capital/sizing-path finding for the rework, reliably reproduced.
This is the pre-cutover gate; the multi-leg residual + capital/sizing-path rework
are the next items before re-attempting the live cutover.
