sessionJWT

[drdrew42]

Initialization

• create sessionJWT from incoming problemJWT request
• retain past answer logs (drop MaThQuIlL_ & others) as array
• support caching of KEPT_EXTRA_ANSWERS
• stop updating sessionJWT once status == max_score
• derive attempts data from sessionJWT if present

Usage

• support forward/backward navigation through past answers
• override problemJWT setting so that past answer view uses static template

Testing

• confirm that problemJWT settings are enforced 'through' the sessionJWT
• reload a problem's state from scratch with a sessionJWT
• confirm that sessionJWT stops updating once status == max_score
• test showHints vs attempts with sessionJWT
