A markdown export of a Canvas course turned rubric tables into images, so I told the user the rubric wording was missing and marked my level judgments as guesses. An accessibility-tree capture saved in an earlier session held the full rubric as button text, and using it changed three of six judgments. Before reporting content as unavailable, grep every earlier artifact in the project, including verification folders and accessibility dumps, for words the missing text must contain. Those dumps can truncate long strings at about 500 characters, so mark cut-off cells instead of completing them.
