Missing context

missing_context turns known gaps into portable facts.

Use cases

• The user asked about a file that is not loaded.
• A source exists but permission is missing.
• The selected context is stale.
• A tool result references an artifact that was not available to the model.
• A peer agent needs a document excerpt before continuing.

Status values

Initial status values: open, requested, waiting, resolved, declined, blocked, and expired.

Fixed rule

Do not hide uncertainty inside a final answer. If missing context materially affects work, record it and surface it to the system that can resolve it.
