Check planted evidence

[drsm79]

Overview

As evidence can be placed in the locker with plant we should have some checks, beyond abandoned evidence, against that. I think something like warnings when within a certain time period of the evidence ttl & errors when within a shorter period would be a good start.

Requirements

• Walk all the external evidence
• Warn if ttl is N days away (N from config, default 21 days?)
• Error if ttl is M days away (M from config, default 7 days?)

Approach

Provide a detailed approach to satisfy all of the requirements listed in the
previous section. This level of detail may not be available at the time of
issue creation and can be completed at a later time.

Security and Privacy

Provide the impact on security and privacy as it relates to the completion of
this issue. This level of detail may not be available at the time of
issue creation and can be completed at a later time. N/A if not applicable.

Test Plan

Provide the test process that will be followed to adequately verify that the
approach above satisfies the requirements provided. This level of detail may
not be available at the time of issue creation and can be completed at a later
time.
