+"""OFFSEC-003 regression backstop — sanitize_a2a_result invariant across all A2A tool exit points.
+
+Scope
+-----
+Every public callable in ``a2a_tools_delegation`` that returns peer-sourced content
+must pass its output through ``sanitize_a2a_result`` before returning to the agent
+context.  These tests inject boundary markers and control sequences from a
+mock-peer response and assert the returned value is the sanitized form.
+
+Test coverage for:
+  - ``tool_delegate_task``            — main sync path
+  - ``tool_delegate_task``            — queued-mode fallback path
+  - ``_delegate_sync_via_polling``    — internal polling helper
+  - ``tool_check_task_status``        — filtered delegation_id lookup
+  - ``tool_check_task_status``        — list of recent delegations
+
+Issue references: #491 (delegate_task), #537 (builtin_tools/a2a_tools.py sibling)
+
+Key sanitization facts (for test authors):
+  • _escape_boundary_markers: replaces "[A2A_RESULT_FROM_PEER]" with
+    "[/ A2A_RESULT_FROM_PEER]" and "[/A2A_RESULT_FROM_PEER]" with
+    "[/ /A2A_RESULT_FROM_PEER]". The escape form is "[/ " (bracket-space).
+    Assertion pattern: assert "[/ A2A_RESULT_FROM_PEER]" in result.
+  • Defense-in-depth injection escape patterns replace SYSTEM/OVERRIDE/
+    INSTRUCTIONS/IGNORE ALL/YOU ARE NOW with "[ESCAPED_*]" forms.
+  • Error path: when peer returns an error-prefixed string (starts with
+    _A2A_ERROR_PREFIX), the raw error text is included in the user-facing
+    "DELEGATION FAILED" message. This is intentional — errors from peers
+    are surfaced as errors, not as sanitized results.
