Control an investigation evidence log

#Page purpose

Register, classify and review investigation evidence while preserving visible custody, integrity, processing and source-link information.

#Before you start

• Sign in as assigned investigators and evidence custodians and confirm WatheeqTech shows /lex/investigations/[id]/evidence; hidden controls indicate that your account lacks the required permission.
• Open the record from its owning register or a trusted notification so you begin with the correct tenant, record identifier and current lifecycle state.
• Collect the reason, authority and supporting evidence required for any governed decision or state transition.

#How to use this page

1. 1
   Verify the record and state

   Confirm the investigation number and access classification, then filter the evidence log by digital, physical, verified or processing state.

2. 2
   Complete the permitted action

   Upload evidence with its source and custody metadata only when authorized, and remove an item only through the governed investigation action.

3. 3
   Confirm the transition

   Review the relationship model, custodian and laboratory state, then export the evidence log and verify its references and integrity values before sharing it.

#Governance and expected result

• Operate only within the tenant, role and record visibility granted to you.
• Record the decision, reason and supporting evidence before completing a governed action.
• Use the page action for the transition rather than changing source data or maintaining a parallel offline status.
• Verify the resulting status, owner, timeline, version or audit event before leaving the page.
