Review comments at @framework/global/tests/rpcqueue_tests.cpp:
- Line 41: Update the Communication_DISABLED test name in
Global_Concurrency_RpcQueueTests so it uses Google Test’s DISABLED_ prefix if
the test should be disabled, and add a comment stating the reason; if it should
run, revert the rename.

Review comments at @framework/global/tests/val_tests.cpp:
- Around line 543-596: Extend ValJson_RoundTrip with list and/or map cases
containing double-valued Val instances, including integral-valued, fractional,
and small scientific-notation values. Assert the serialized representation and
that parsing preserves the original values and double type; use the existing
expectList or expectMap helpers.

Review comments at @framework/rcommand/tests/typedcommand_tests.cpp:
- Around line 156-179: Extend the TypedCommand tests around TestCommand and
fromInputParams to verify missing required fields, an unknown e_val enum string,
a string supplied for i_val, a negative value for uVal, and an i_val outside its
declared range each return false without throwing. Add a round-trip test using
toOutputParams<TestCommand> and fromOutputParams<TestCommand>.

Review comments at @framework/rcommand/typedcommand.h:
- Around line 183-190: Update the Field overload of fromVal to validate numeric
bounds after converting the input: reject failed conversions, and for arithmetic
T reject values below f.min or above f.max when those bounds are set. Assign the
converted value to the member only after validation; preserve the existing null
and required-field behavior.

Walkthrough

The command framework adds typed command contracts, field and enum conversions, and typed dispatch. Menu and toolbar models can carry command parameters. Val adds optional and generic type conversions, plus list and map formatting and parsing. Command data type declarations and related dock and VST schemas are updated. MCP schemas now represent type formats, and JsonValue conversions handle MCP arguments and results. A constructor is also added to MnemonicString.

Priority: Normal

Merge Risk: Moderate · previous review a6fe7

Typed commands can accept values outside their advertised limits, while unresolved conversion, schema, and typed UI API problems could affect callers. Resolve these material issues before merging.

90-95: Trivial · Functional Correctness · Quick win

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.

BaseContract::get hides invalid or missing enum input behind C::def.

enum_val now returns std::optional. get discards that result. A missing key, an empty string, and an unknown string all return C::def. The caller cannot tell these cases from an explicit default value.

The typed-command path in internal::fromVal uses enum_val directly. It rejects unknown strings. get is inconsistent with that path. The contract also has no way to mark a value as required.

Return std::optional from get. Let the caller choose between value_or(C::def) and a "missing required field" error.

♻️ Proposed change
-    static decltype(C::def) get(const muse::rcommand::Params& params)
+    static std::optional<decltype(C::def)> get(const muse::rcommand::Params& params)
     {
-        auto sval = params.at(C::key).toString();
-        auto value = enum_val(sval);
-        return value ? *value : C::def;
+        return enum_val(params.at(C::key).toString());
     }

Based on learnings: reject empty or unset values for required enum-like fields with a clear "missing required field" error instead of selecting a default.

Minor · Reject non-finite results in doToDouble() for string input. · val.cpp:196-200

framework/global/types/val.cpp:196-200
Minor · Functional Correctness · Quick win

Reject non-finite results in doToDouble() for string input.

std::stod accepts the strings "nan", "inf" and "infinity", and it returns NaN or ±Inf for them. The String branch then returns that value as a valid std::optional<double>. Val strings come from outside input, such as MCP JSON strings and command parameters. A typed command with a double field can therefore receive NaN or Inf. A NaN Val double that reaches doToInt() and doToInt64() is cast with static_cast<int> and static_cast<int64_t>, which is undefined behavior. Return std::nullopt when the parsed value is not finite. This needs <cmath>.

Proposed fix
         try {
-            return std::stod(str);
+            const double parsed = std::stod(str);
+            if (!std::isfinite(parsed)) {
+                return std::nullopt;
+            }
+            return parsed;
         } catch (const std::exception& e) {
             return std::nullopt;
         }

Based on learnings: validate floating-point values parsed from external sources with std::isfinite.

The _DISABLED suffix does not disable this test.

Google Test disables a test only when the test name or suite name starts with DISABLED_. The name Communication_DISABLED does not start with that prefix. The test still runs, so the rename does not do what its name implies. If the test is flaky, use DISABLED_Communication and add a comment with the reason. If the test must run, revert the rename. The PR has no description, so the intent is unclear.

Add double values to the ValJson round-trip test.

No case in ValJson_RoundTrip uses a Val double. Cases such as Val(42.0), Val(22.12) and Val(1e-9) would show the type and precision loss in appendValue. Add these cases, or document that doubles are not round-trip safe.

Extend ValJson_RoundTrip with list and/or map cases containing double-valued Val
instances, including integral-valued, fractional, and small scientific-notation
values. Assert the serialized representation and that parsing preserves the
original values and double type; use the existing expectList or expectMap
helpers.

Add negative and output-direction tests.

The tests cover only valid input. They do not cover the cases where fromInputParams must return false, or the output direction.

  • Add a case with a missing required field (b_val or i_val). Expect false and no exception.
  • Add a case with an unknown enum string for e_val.
  • Add a case with a wrong value type, such as a string for i_val.
  • Add a case with a negative value for uVal. The current code wraps it to a large unsigned value.
  • Add a case with an out-of-range i_val, such as 1000. The input schema declares the range -100..100.
  • Add a round-trip test for toOutputParams<TestCommand> and fromOutputParams<TestCommand>. No test exercises these functions.

These tests would also settle the open questions on params.at(f.key) and Contract<T>::enum_val in typedcommand.h.

Enforce the min and max declared in Field during input conversion.

makeArg publishes min and max in the input schema. fromVal(S&, const Field&, const Val&) never checks them. A client can send i_val = 1000, although the schema declares -100..100. fromInputParams returns true, and the callback receives the out-of-range value.

Validate the range after conversion. Limit the check to arithmetic types, because Field::min exists for every T.

Review comment at @framework/rcommand/typedcommand.h around lines 183 - 190:
Update the Field overload of fromVal to validate numeric bounds after converting
the input: reject failed conversions, and for arithmetic T reject values below
f.min or above f.max when those bounds are set. Assign the converted value to
the member only after validation; preserve the existing null and required-field
behavior.
