One interface method with two preconditions meant a caller's failure mode depended on which feed happened to be configured. Bitget now self-initializes like the Binance/OKX feed, matching Chainlink and Pyth which fetch both legs on every call. The batch path is unchanged: it primes ETH before the loop so the self-init branch never fires, keeping a cycle at N+1 requests against rate-limited endpoints rather than 2N.

Bound the Pyth exponent magnitude so a malformed expo cannot ask big.Int for 10^2147483648, and reject publish times ahead of the local clock instead of accepting the whole staleness window. Reject NaN and infinities before constructing a big.Float: they pass a bare `<= 0` test, and NaN panics while an Inf survives until Float.Int returns nil. Bitget had the same parser twice, one of which had no positivity check at all. Give Chainlink calls their own deadline. The service context has none and the RPC transport imposes none, so a hung endpoint would stall the updater forever and the fallback feeds would never be reached. Wrap a single configured feed in FallbackPriceFeed rather than returning it directly. That bypassed the completeness check, letting a partial or empty CEX batch through as success, which the updater then recorded as a successful cycle and used to advance the last-successful-update timestamp. Gate the devnet token pre-registration on fundDevAccounts so it no longer writes into mainnet and testnet genesis, correct the L2WETH balance slot from 3 (_name) to 0 (_balances) via an explicit NeedBalanceSlot flag, since a zero slot is a real slot and cannot double as "no slot", and move the placeholder token addresses out of the precompile range. Fix the quick-start config, which enabled Binance and OKX without their mappings, and drop the documented registry-address and token-ID controls, which have no corresponding flags.

Together that meant a provider covering part of the active set could never contribute: with any active token missing from the oracle mappings, Chainlink and Pyth failed every cycle and every token silently came from a CEX. The devnet configuration this repo documents hits exactly that, since genesis registers three tokens while the oracle mappings cover two. Feeds now omit tokens they have no mapping for rather than failing the batch, which is what the CEX feeds already did, and the fallback layer resolves across feeds in priority order, passing each one only the tokens still unresolved. A token that no feed can price no longer blocks the rest of the cycle; it is reported by its absence from the returned map, and the updater surfaces it through a warning and the new unresolved_tokens gauge. A cycle that resolves nothing at all is still an error, so a total feed outage cannot be recorded as a successful update.

The Chainlink path reads an L1 block timestamp, which is always in the past, but publish_time is the publisher's near-real-time wall clock at second granularity, so host clock drift would have turned into a total Pyth outage. Allow 30s of skew while still refusing prices dated far into the future, which was the actual defect: the previous check accepted anything inside the staleness window, nearly an hour at the default.

That collapses to a scale of 1 for the two 18-decimal tokens, and since priceRatio is truncated to a uint256, any token cheaper than ETH then stores a ratio of 0. BGB was dropped every cycle with only a "Skipping zero price" warning and calculateTokenAmount reverted for it, which defeats the one token in the set that exercises a CEX-specific feed. Scale cancels out of calculateTokenAmount, so its only role is preserving significant digits, and 10^decimals is the convention L2TokenRegistry's own tests use. It also makes the stored ratio equal 10^18 * tokenPrice/ethPrice for every token regardless of decimals. Also drop BGB from the documented OKX mapping, since OKX does not list it.
