"""Security tests for Jira Project Knowledge.
|
||||
|
||||
Covers the mandatory production contract:
|
||||
- Cross-project isolation at retrieval boundary
|
||||
- Caller project_id cannot redirect target
|
||||
- Untrusted content (prompt injection) is fenced, not executed
|
||||
- Credential redaction in errors and logs
|
||||
- Output bounds prevent context-window exhaustion
