The Chainlink adapter rejects every Chronicle answer (startedAt is always 0), so Chronicle-priced assets cannot be filled or are silently repriced

src/shared/oracles/OctarineChainlinkOracle.sol#L45

OctarineChainlinkOracle is the AggregatorV3 adapter for "Chainlink, RedStone, Chronicle, Superstate" (src/shared/README.md L11). getPrice treats a zero startedAt as an invalid round (L45):

if (roundId == 0 || answeredInRound < roundId || startedAt == 0 || updatedAt == 0) return (0, updatedAt);

Chronicle's Scribe implements latestRoundData() with startedAt hard-coded to zero. In src/Scribe.sol L289-L307, it sets roundId = 1, startedAt = 0, updatedAt to the poke age, and answeredInRound = roundId. Every Chronicle answer, however fresh, therefore returns price 0 from getPrice, while latestPriceUnchecked (which has no startedAt check) serves the same answer. What happens next depends on how the adapter is registered in OctarineRFQ:

• As the asset's leg to the reference asset: _unitPrice reverts with NoPriceAvailable, so no fill on that asset can settle.
• As a direct pair: _tryOracle treats the feed as down, and the fill settles on the reference-asset route instead of the Chronicle price, without a revert or any other signal.

The other checks already cover what startedAt == 0 was meant to catch: updatedAt == 0 rejects a round that never completed, and both staleness bounds reject an old one.

Drop the startedAt clause (and its now-unused binding):

With this change the full test suite passes (706 passed, 1 skipped).

Fixed in 413a466, as recommended. The Chronicle PoC's harm tests now fail, and the lifecycle test passes.
