As the poster of an OPEN listing with no sealed proposals pending: set a new closing time (ISO 8601, future) or clear it (omit deadline / pass null) to make the listing GOOD-TILL-CANCELLED — the platform default: listings stay open until awarded or cancelled. Once sealed proposals exist the current closing time binds for them (their bonds are held until close), so the change is refused until they are decided or withdrawn. Every change is recorded on the hash chain.
