Inline comments:
In `@config/das.json`:
- Around line 147-155: Document the breaking configuration migration near
schema_version in config/das.json: explain that existing 1.0.1 configurations
must be upgraded to 1.1.0 and add agents.base_proxy.params.orchestration_schema.
Preserve all existing key names and structure while adding only the required
upgrade guidance.
In `@src/agents/BaseProxy.cc`:
- Around line 19-28: Remove the constructor-level api_mutex lock from
BaseProxy::BaseProxy() so initialization can call set_orchestration_schema()
without recursively locking the same non-recursive mutex; preserve the existing
field initialization and schema setup.
In `@src/agents/evolution/QueryEvolutionProcessor.cc`:
- Around line 580-585: Guard the average-generation calculation in
QueryEvolutionProcessor so it runs only when at least one generation has
completed, preventing division by zero when shutdown occurs before
generation_count is incremented. Preserve normal averaging for completed
generations, and add a regression test covering monitor shutdown while the first
cycle permission is pending.
In `@src/commons/SystemParameters.h`:
- Line 21: Add a brief Doxygen /** ... */ documentation block immediately above
the public get_base_proxy_params() declaration in the header, describing what
the method returns.
In `@src/commons/SystemParametersValidation.cc`:
- Around line 146-152: Update orchestration_schema validation in
SystemParametersValidation.cc to handle signed values before accessing the
unsigned variant, rejecting negative values through the existing RAISE_ERROR
path; update system_parameters_test.cc to expect runtime_error for negative
input.
In `@src/tests/cpp/base_proxy_test.cc`:
- Around line 10-12: Update TestEnvironment::SetUp to initialize parameters via
das_test::init_test_system_parameters_singleton() and ensure the test depends on
//tests/cpp/test_commons:test_system_params, rather than using the undeclared
absolute /opt/das/config/das.json path.
In `@src/tests/cpp/BUILD`:
- Around line 1117-1120: In src/tests/cpp/BUILD at lines 1117-1120, update the
deps for base_proxy_test and the custom-main targets request_selector_test,
bus_command_router_test, pattern_matching_query_test, processor_test,
morkdb_test, inmemorydb_test, and remote_atomdb_test to use gtest instead of
gtest_main, while retaining each target’s custom main(). In
src/tests/cpp/base_proxy_test.cc at lines 37-40, no direct change is required;
its custom main is preserved by the BUILD dependency fix.

WIP towards #1208
In this PR we add an API in BaseProxy to allow any concrete Proxy to control the execution of a processor according to an orchestration algorithm. This is applicable to processors that process their commands in multiple cycles (e.h. Query Evolution and LCA). Currently we implemented only one orchestration method with is a basic "wait for an OK before starting an each cycle". SO now all proxies can have a new parameter ORCHESTRATION_SCHEMA which is set to NONE by default. Ciclic processors will use this parameter to control when new cycles are started.
In order to implement the above, we needed to make some further changes in BaseProxy because previously it had no parameters. In addition to this, the config JSON schema was also updated to 1.1.0 so we needed to make changes in various parts of the code.
New test cases were added to test the implemented behavior and a bug in a previous test was also fixed: system_parameters_test was not considering the most recent schema version of the config JSON. It was using a hard0-coded "1.0" string (it was not breaking because the JSON with the wrong version was already suppose to throw anyway because of other intentional mistakes).
