-/**
- * Unit tests for buildDeployMap — the pure tree-traversal core of
- * useOrgDeployState.
- *
- * What is tested here:
- *   - Root / leaf identification via parent-chain walk
- *   - isDeployingRoot: true when any descendant is "provisioning"
- *   - isActivelyProvisioning: true only for the node itself in that state
- *   - isLockedChild: true for non-root nodes in a deploying tree
- *   - isLockedChild: also true for nodes in deletingIds (even if not deploying)
- *   - descendantProvisioningCount: non-zero only on root nodes
- *   - Performance contract: O(n) single-pass walk — tested by verifying
- *     correctness across 50-node trees (n=50, all cases above)
- *
- * What is NOT tested here (hook integration — appropriate for E2E):
- *   - The useMemo / Zustand subscription wiring
- *   - React Flow integration (flowToScreenPosition, getInternalNode)
- *
- * Issue: #2071 (Canvas test gaps follow-up).

-"""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: inserts ZWSP (U+200B) before '[' at line-start.
-    The substring "[A2A_RESULT_FROM_PEER]" IS STILL in the output (preceded by ZWSP).
-    Assertion pattern: assert ZWSP in result.
-  • _strip_closed_blocks: removes everything after the closer.
-    Assertion pattern: assert "hidden content" not in result.
-  • 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.
