permissions.py (authorization Rule/Ruleset model) is consumed across all
MAC subagents + the permissions middleware, with a single external
consumer (user_tool_allowlist service) -> move to
multi_agent_chat/shared/permissions.py and repoint all 42 sites.
deliverable_wait.py (wait_for_deliverable) is used only by the podcast and
video_presentation deliverable tools -> colocate into
subagents/builtins/deliverables/.
No behavior change; import-all + permission/allowlist/deliverable unit
tests stay green.
receipt.py (Receipt model + make_receipt) and receipt_command.py
(with_receipt Command helper) are a tight pair used only by MAC subagent
tools, the graph state, and the kb_persistence middleware -- no external
code imports them (the streaming tool_end handler only references them in a
docstring). Move both into a dedicated receipts/ package
(receipts/receipt.py + receipts/command.py) and repoint importers.
No behavior change; import-all + receipt/deliverable unit tests stay green.
- Added new environment variables for controlling task execution limits, including `SURFSENSE_SUBAGENT_INVOKE_TIMEOUT_SECONDS`, `SURFSENSE_TASK_BATCH_CONCURRENCY`, and `SURFSENSE_TASK_BATCH_MAX_SIZE`.
- Updated documentation to reflect new batch processing capabilities for `task` calls, allowing for concurrent execution of multiple subagent tasks.
- Improved error handling and receipt generation for deliverables, ensuring consistent feedback on task status.
- Refactored middleware to incorporate search space ID for better task management.
