11L is a too huge gap to leave out. Since you've done 4 months here, I suggest to start preparing again, but at the same time try to appear to your manager like you're working super hard. After two more months, ask for a one on one call and try to discuss future plans, but only related to career. Tell that you're looking to get promoted, and ask what are the expectations for the next level, so you can work on them.
That should get you good rapport with your manager. Then, start noting things down and have ChatGPT reword that to show more impact. Every single thing you did. Even if you helped a peer, record that. After three more months, you got around 9 months of experience, so ask for another one on one and take feedback. Raise all those reworded points to show impact. Also discuss about future expectations.
Next, just before expected cycle, tell your manager informally that you're sensing that the market is growing back up, and ask about the plans for revenue growth of company. Then informally bring up that you did notice the 11L gap that was left out, but tell that you're looking for help from your manager. Let them know that you have noticed. Again bring up all your reworded work till then with your manager.
You'll definitely get a promotion, and most probably a cover up for package too. Then, simply take a switch. You should've been preparing for almost an year by that time. Remember, it is a long term game. Not an immediate one.
