Scale remaining order amounts exactly, not through basis points  ProjectOpenSea/seaport-js#991
A basis-points detour under-scaled partial fills. On a 9 ETH order partially filled, the default fulfill path built a 5.9994 ETH transaction where the contract required 6, reverting an ordinary fill with InsufficientNativeTokensSupplied. Traced to a sibling fix that never reached these two functions, verified against seaport-core that the on-chain fill fraction is exact-or-revert, and covered by a regression test that fails on main with the exact wei mismatch.

Add a reusable chain_id query-param parser  getoptimum/optimum-common#191
A single reusable uint64 chain_id parser for the shared library, closing the tracking issue and standardizing what had been two near-duplicate implementations across services. Shipped an option-based API first, then simplified to a single flag on maintainer review.

Allow hyphen in CAIP-2 namespace per spec  agentcommercekit/ack#176
A namespace regex rejected spec-legal hyphens. The fix also corrected a did:pkh test that had been passing only because of the same wrong pattern.

Exclude soft-deleted executions from workflow delete pre-check  KeeperHub/keeperhub#2123
A soft-delete regression left the delete pre-check returning a false 409 for workflows whose run history had already been purged. Traced to the exact commit that moved executions to soft-delete without updating the guard, fixed by excluding the soft-deleted rows.
