Overview

Operator can update the responses to an ongoing audit.

Deliverables

liq policies audits update <path>:

• For each question (in the TSV), operator is given an option to answer.
• For unanswered questions, the operator can: 'affirm', 'deny', 'not applicable' or 'skip'.
• An 'affirm' gives the option to add notes.
• Both 'deny' and 'not applicable' require explanatory notes to be added.
• If the question is already answered, the answer, along with any notes, are displayed and the user can 'accept' or 'update'. Accepting moves on to the next question, updating drops user into the same options as if there was no answer. Note that 'skip'ping a previously answered questions has the effect of deleting the previous answer.
• As each question is answered, a tentative log entry is generated in the standard format (see #165) with descriptions '<affirmed/denied/skipped> "" [with notes]'
• The entire audit is displayed back to the the user with actions for each question.
• Once verified, the final action logs are generated and processed via the signature and commits as per #165.

Start by reviewing the liq policies audits update <path> deliverables and issue #165 for the standard log format and signature/commit flow. Define the interaction for unanswered and previously answered questions, including notes and skip behavior. Done means the full audit can be reviewed, verified, and processed with final action logs.
