Default trading path now uses PythSponsor to pay Pyth price update fees instead of splitting from tx.gas. The sponsor Fund hot-potato is created before Hermes fetch, split for each feed update, then reimbursed onto the TradingRequest (adding PythSponsorRule witness). - Add pyth_sponsor_rule to codegen pipeline and constants - Add pythSponsorRulePackageId / pythSponsorId to WaterXConfig - Modify buildPythPriceUpdateCalls to accept optional sponsorFund - New addPriceFeeds default: sponsor-paid Hermes+Pyth update - selfPayPyth param opts out to legacy gas-paid path - Add reimburseSponsorFund helper (utils/sponsor.ts) - Thread sponsorFund through all trading builders and user functions - Remove updatePythPrice:true from e2e tests (default sponsor covers it) - Add xStock markets to lifecycle e2e test coverage Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- fetchSimulatedUsdPricesForBases falls back to per-base simulates when batch TX fails (DEEP's broken aggregator no longer blocks all markets) - Add per-base price guard in trading-negative and prd-product-coverage - Fix cancelOrder test: use scaled triggerPrice + wildcard orderTypeTag - Adjust BTC e2ePtb sizes to match on-chain position (size=588) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
…iceFeeds - buildResolveSize now uses trading::resolve_size (takes collateralPriceResult) instead of deprecated trading::resize - Export addPriceFeeds for test helpers and custom PTB construction - Simplify simulate-resize-size helper to use addPriceFeeds Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Exact max leverage (positive) and max+1 (negative) now use leverage-only path with on-chain resolve_size — no approxPrice off-chain estimate. Removed unused fetchSimulatedUsdPricesForBases import from prd tests. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Withdraws nearly all collateral from existing positions — verifies on-chain err_exceed_max_leverage (104) abort when remaining collateral would push effective leverage above market max. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Guard against undefined prices[base] (e.g. DEEP broken aggregator) in scratchSimulateOpenApproxOracle — prevents NaN→BigInt crash in CI. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
