Kiran, Akemi, and Javier are all colleagues who work for a tech company. They are collaborating on a secret project that involves designing a new software application. The details of the project are highly confidential, and only these three, along with their manager Leela, are privy to the specifics. One Monday morning, Kiran calls in sick, and thus is absent from the office and a key meeting where an important update to the project is discussed. Akemi, who was present in the meeting, had to leave early for a dental appointment and missed the last part of the discussion. Javier stayed for the entire meeting. After the meeting, Leela adds new information to the project documentation online, which includes a significant change in the project's direction that was decided during the final part of the meeting.

Throughout the week, Kiran works from home and is not updated on the changes due to his absence. Unaware of the update, Akemi returns to the office after her dental appointment and continues working based on the knowledge she had before leaving the meeting. Javier is aware of the change but is under the impression that Leela has sent out an office-wide email summarizing the meeting's outcomes, which is not the case. The next day, Javier works from home, and Leela goes on a business trip for the rest of the week without checking if everyone is on the same page regarding the project. 

By Friday, Kiran is feeling better and returns to the office. He has a conversation with Akemi regarding the progress of the project. Both are oblivious to the change that has occurred. Later that day, when Javier checks the project documentation online from home, he realizes that there was no email sent by Leela, and he assumes that Kiran and Akemi have already seen the updated documentation.

Given this situation, assess the knowledge state of each team member regarding the project's direction by the end of the week, and determine who is aware or unaware of the changes, based on their unique circumstances.
Kiran, who has been sick and working from home, has not been privy to the meetings and updates that took place during the week. His only source of information about the project's progress would have been any formal communication such as emails or the project documentation online. Since Leela did not send out a summary email and Kiran did not check the updated documentation online, it stands to reason that he is unaware of the new direction the project has taken.

Akemi, on the other hand, attended the start of the meeting but had to leave before it concluded. She is thus partially updated but missed the significant development that occurred in the final part of the meeting. Her early departure and the lack of subsequent communication mean she remains unaware of the pivotal change. Furthermore, her conversation with Kiran would not have enlightened her, as he too was oblivious to the updates.

Javier is the only one among the three colleagues who knows about the change in the project's direction, having stayed for the entire meeting. However, he is under the mistaken belief that an office-wide email has been sent by Leela summarizing the critical outcomes of the meeting. This belief is a result of his assumption rather than a confirmation, and it prevents him from realizing that his colleagues are out of the loop. Without checking if Kiran and Akemi accessed the updated documentation online, his assumption leads him to inaccurately think they are also aware of the changes.

Leela, although the manager and the person responsible for documenting the change in the project's direction, is on a business trip. She has neglected to verify that all members of the team have received the updated information. Unless she had previously set an automatic alert for when the documentation is accessed, there is no indication that she has any knowledge of who among her team is up to date with the project details by the end of the week.

By Friday, the state of knowledge among the colleagues is such that Kiran and Akemi remain uninformed about the latest project developments. Javier, while aware of the changes himself, incorrectly assumes that the others are also informed due to a non-existent email he believes was sent by Leela. Leela is out of contact and thus cannot contribute to the present understanding of the project amongst the team. Without direct communication or confirmation from the manager, the misunderstanding persists, and the team members finish the week with a varying understanding of the project's status.
