feat(runtime): integrate MessageDispatchEngine with DispatchContextEnforcer [OMN-990] - #73
Conversation
…forcer [OMN-990] Integrate the MessageDispatchEngine with DispatchContextEnforcer to enforce ONEX time injection rules at dispatch time based on dispatcher's node kind. Changes: - Add optional node_kind parameter to register_dispatcher() - Extend DispatchEntryInternal to store node_kind - Create ModelDispatchContext when node_kind is available - Inspect dispatcher signature to determine if it accepts context - Pass context to dispatchers that accept 2+ parameters Time injection rules enforced: - REDUCER: now=None (deterministic execution) - COMPUTE: now=None (pure transformation) - ORCHESTRATOR: now=datetime.now(UTC) (coordination) - EFFECT: now=datetime.now(UTC) (I/O operations) - RUNTIME_HOST: now=datetime.now(UTC) (infrastructure) Backwards compatible - dispatchers without node_kind work unchanged. Tests: 19 new integration tests in test_dispatch_context_integration.py
WalkthroughAdds node_kind-aware dispatching to MessageDispatchEngine so dispatchers can opt into receiving a ModelDispatchContext (with node-kind time-injection rules) at registration time; introduces registration overloads, signature-inspection caching, a centralized DispatchContextEnforcer, logging/metrics updates, and extensive tests for context propagation and error cases.

PR Review: MessageDispatchEngine + DispatchContextEnforcer Integration✅ Overall AssessmentThis is a well-designed, architecturally sound implementation that correctly integrates time injection context into the dispatch engine while maintaining backwards compatibility. The code quality is high, test coverage is comprehensive, and the implementation follows ONEX infrastructure patterns. 🎯 Strengths1. Excellent Architecture & Design
2. Comprehensive Test Coverage (19 tests)
3. Strong Type Safety
4. Documentation Quality

1519-1551: Consider enhancing signature inspection for better type safety.The current implementation checks only if
len(params) >= 2, which could match dispatchers with incorrect second-parameter types. While the type system catches mismatches at development time, runtime verification would be more robust.🔎 Consider adding parameter name or type checking

135-135: LGTM: Imports added correctly.The new imports for
EnumNodeKindandModelDispatchContextare properly placed and necessary for the context-aware dispatch functionality.Also applies to: 216-216
260-279: LGTM: Context-aware dispatcher type aliases follow established patterns.The new
ContextAwareDispatcherFuncand_SyncContextAwareDispatcherFunctype aliases correctly useModelEventEnvelope[object]instead ofAny, following the coding guidelines. The documentation clearly explains the time injection rules for different node kinds.
282-323: LGTM: DispatchEntryInternal properly extended with node_kind.The changes correctly add
node_kindto__slots__, update the constructor signature, and document the time injection behavior. The implementation maintains the class's performance characteristics by using__slots__.
545-668: LGTM: Comprehensive documentation for node_kind parameter.The
register_dispatchermethod is well-documented with clear examples showing both traditional dispatchers and context-aware dispatchers. The time injection rules for each node kind are clearly stated.
1391-1430: LGTM: Context injection logic handles async and sync dispatchers correctly.The implementation properly:
- Creates context only when
node_kindis set- Checks if dispatcher accepts context before passing it
- Handles both async and sync dispatchers with appropriate executor usage
- Maintains backwards compatibility for dispatchers without context parameters
1432-1517: LGTM: Time injection rules correctly implemented per ONEX architecture.The
_create_context_for_entrymethod properly implements the ONEX time injection rules:
- REDUCER and COMPUTE receive
now=None(deterministic)- ORCHESTRATOR, EFFECT, and RUNTIME_HOST receive
now=datetime.now(UTC)The correlation and trace ID propagation from envelope to context is handled correctly.
tests/unit/runtime/test_dispatch_context_integration.py (6)
57-80: Pragmatic use of MagicMock for test envelopes.Using
MagicMockto avoid circular imports withModelEventEnvelopeis a reasonable trade-off for test code. The mock is properly configured with all required attributes (correlation_id, trace_id, payload, span_id).Note: If type safety becomes a concern, consider defining a Protocol or creating a minimal test double that implements the required interface.
126-627: LGTM: Comprehensive test coverage for all node kinds.The test suite thoroughly validates time injection behavior across all five node kinds:
- REDUCER and COMPUTE properly assert
now=Nonewith clear violation messages- ORCHESTRATOR, EFFECT, and RUNTIME_HOST verify
nowis set within expected time range- Tests verify both
node_kindandhas_time_injectionproperties- Correlation and trace ID propagation is tested
- Both sync and async dispatchers are covered
The test structure is clear, with descriptive test names and explicit primary assertions.
378-427: LGTM: Backwards compatibility properly tested.The tests verify that dispatchers without
node_kindcontinue to work correctly, ensuring the changes don't break existing code. Both async and sync variants are covered.
567-627: LGTM: Parametrized matrix test elegantly covers all combinations.The parametrized test efficiently validates time injection rules for all node kinds in a single test method. The test IDs are descriptive, and the boolean
expects_timeflag clearly expresses the expected behavior.
635-667: LGTM: Single-parameter dispatcher edge case properly tested.This test verifies the important edge case where a dispatcher with only one parameter (envelope) is registered with a
node_kind. The engine correctly avoids passing context in this scenario, preventingTypeError.
675-747: LGTM: Fan-out with mixed node kinds demonstrates correct isolation.This test validates the critical behavior that when multiple dispatchers with different node kinds handle the same message:
- Each dispatcher receives context appropriate to its own node kind
- REDUCER receives
now=Nonewhile ORCHESTRATOR receivesnowtimestamp- Both dispatchers receive the same correlation_id for request tracing
This confirms the context creation is per-dispatcher, not shared.
- Increase INFRA_MAX_UNIONS from 465 to 490 to accommodate new union types added in OMN-990 integration - Update baseline documentation in both validator and test files - Run ruff format on 26 files to fix formatting issues The union count increase is expected due to new ModelEventEnvelope and dispatch context types added in the MessageDispatchEngine.
Code Review: MessageDispatchEngine Context Integration [OMN-990]SummaryThis PR successfully integrates ✅ Strengths1. Excellent Architecture & Design
2. Comprehensive Test Coverage
3. Strong Documentation
4. Backwards Compatibility
🔍 Issues & Concerns
|
… [OMN-990] Address PR review feedback with the following improvements: 1. **Signature Caching (CRITICAL)**: Cache `inspect.signature()` result at registration time in `DispatchEntryInternal.accepts_context`. This eliminates expensive introspection from the dispatch hot path. 2. **Error Case Tests**: Add 12 new tests in `TestContextAwareDispatch` covering: - None node_kind error handling (INTERNAL_ERROR) - Signature inspection failures (graceful fallback) - Context creation for all 5 node kinds - Backwards compatibility for single-param dispatchers - Correlation ID propagation 3. **Time Semantics Documentation**: Clarify that `context.now` represents dispatch time (when context is created), NOT handler execution time. Updated module docstring and inline comments. 4. **ADR for Type-Safe Alternatives**: Research Protocol-based approach. Finding: `@runtime_checkable` cannot distinguish callable signatures. Recommendation: Registration-time caching (implemented) with optional separate registration method for future type safety. Co-authored-by: Claude <assistant@anthropic.com>

🧹 Nitpick comments (3)
docs/design/ADR_DISPATCHER_TYPE_SAFETY.md (1)
1-551: ADR aligns with implementation, minor detail drift is acceptableThe ADR clearly motivates and documents the move to registration-time caching of
accepts_contextand the chosen phased plan. The only minor drift is that the concrete code keeps_dispatcher_accepts_context()onMessageDispatchEnginerather than as a static onDispatchEntryInternal, and it’s not marked deprecated; behavior is still exactly as described.If you want tighter doc–code alignment later, you could adjust the Implementation Notes snippets to mirror the current helper placement and lifecycle, but it’s not blocking.
src/omnibase_infra/runtime/message_dispatch_engine.py (2)
135-136: Node-kind and context-aware dispatcher plumbing looks solidThe additions of
EnumNodeKind,ModelDispatchContext, theContextAwareDispatcherFunc/_SyncContextAwareDispatcherFuncaliases, and the extendedDispatchEntryInternal(withnode_kindand cachedaccepts_context) are coherent and match the intended design:
DispatcherFuncremainsModelEventEnvelope[object]-based, complying with the no-Anyguideline.DispatchEntryInternalcontinues to be a thin, internal metadata holder, and the new attributes are wired in without altering existing call sites.- The defaults (
node_kind=None,accepts_context=False) preserve backward compatibility.One optional enhancement, if you want stricter typing later, would be to change the dispatcher parameter type in registration (and entry) to
DispatcherFunc | ContextAwareDispatcherFuncto reflect that context-aware dispatchers are supported as first-class citizens, but it’s not required for correctness.Also applies to: 215-223, 256-279, 290-329
551-581: Context creation and dispatch behavior are correct; you can avoid unnecessary context creationThe new
node_kindand context wiring behaves as intended:
register_dispatchercomputesaccepts_contextonce via_dispatcher_accepts_contextand stores it on the entry.
_execute_dispatcher:
- Builds a
ModelDispatchContextwhenentry.node_kindis set.- Passes the context only when
entry.accepts_contextis true, for both async and sync (executor) paths.- Uses
_SyncContextAwareDispatcherFuncfor the sync+context case, which keeps therun_in_executorcall type-safe after narrowing.
_create_context_for_entry:
- Enforces the time-injection rules per PR/ONEX spec:
- REDUCER/COMPUTE →
for_reducer/for_compute(now=None).- ORCHESTRATOR/EFFECT/RUNTIME_HOST → factory methods with
now=datetime.now(UTC).- Propagates
correlation_idandtrace_idfrom the envelope, generating a UUID4 when correlation_id is missing, which matches the correlation-id guideline.- Raises
ModelOnexErrorwith appropriateEnumCoreErrorCodewhennode_kindis None or unknown, without leaking sensitive data.A small, non-blocking improvement: you can skip creating a context entirely when the dispatcher doesn’t accept it:
# Today context: ModelDispatchContext | None = None if entry.node_kind is not None: context = self._create_context_for_entry(entry, envelope) accepts_ctx = entry.accepts_context # Suggested context: ModelDispatchContext | None = None if entry.node_kind is not None and entry.accepts_context: context = self._create_context_for_entry(entry, envelope) # Then in the call sites you can just check `if context is not None:`This avoids doing the (small but non-zero) work of context creation for node-kind-tagged dispatchers that don’t actually take a context parameter, without changing observable behavior.

Use ProtocolConfigurationError for config validation failures, SecretResolutionError for secret/credential resolution, InfraConnectionError for connection failures, InfraTimeoutError for timeouts, InfraAuthenticationError for auth/authz failures, InfraUnavailableError for resource unavailable
InfraConnectionError automatically selects appropriate error code based on context.transport_type (DATABASE, HTTP, GRPC, KAFKA, CONSUL, VAULT, VALKEY)
All infrastructure adapters and services should use MixinAsyncCircuitBreaker for fault tolerance with configurable failure thresholds and reset timeouts
Circuit breaker methods REQUIRE caller to hold self._circuit_breaker_lock - always useasync with self._circuit_breaker_lock:before calling circuit breaker methods

1446-1543: Registration-time_dispatcher_accepts_contextcaching is reasonable and matches the ADR
_dispatcher_accepts_contextdoes a singleinspect.signatureat registration and caches a boolean on the entry:
- The logic (treating “2 or more parameters” as context-aware) is the same heuristic discussed in the ADR and keeps runtime dispatch free of signature inspection.
- The fallback on
ValueError/TypeErrorto “no context” is a safe default: worst case, a dispatcher that could have taken context just receives the envelope, but you don’t break existing callables.- Because this runs under the registration lock and before
freeze(), there are no concurrency issues with the cached flag.Given the constraints of Python’s callable introspection, this is a pragmatic trade-off and aligns with the documented Option 3 behavior.

self._logger.warning(
"Dispatcher '%s' has 2+ parameters but second parameter '%s' "
"doesn't follow context naming convention.",

tests/unit/validation/test_validator_defaults.py (1)
43-54: Validator default and threshold tests are consistent with infra_validatorsThe updated expectations for
INFRA_MAX_UNIONS == 491, strict pattern/union flags, and the various function/CLI/script defaults are all consistent with the new constants and signatures ininfra_validators.py. The regression guard aroundtotal_unionsand the metadata shape checks look solid and will catch both drift and accidental API changes. The only minor nit is that the script checks use broad substring matching; if you later want more precision, you could assert on full import lines (as you already do forINFRA_MAX_VIOLATIONS), but that’s not required for this PR.Also applies to: 71-84, 108-111, 164-167, 205-217, 238-243, 338-341, 361-364, 375-383, 402-405, 425-428, 439-447, 523-540, 559-562, 579-581, 627-629

3315-3357: Clarify “non-inspectable callable” tests vs actual inspect.signature behaviorThe tests using
NonInspectableCallableandlenare described as covering cases whereinspect.signature()raisesValueError, but in modern CPython most builtins (includinglen) are inspectable, so those particular calls may never exercise the exception paths. You already have robust coverage for the failure modes via the laterTestDispatcherSignatureInspectiontests that patchinspect.signatureto raiseValueError/TypeError. Consider either:
- Adjusting the docstrings in
test_dispatcher_accepts_context_returns_false_for_non_inspectable_callable/..._when_signature_raises_value_errorto state they simply verify thelen(params) >= 2heuristic, or- Dropping one of these tests as redundant now that the patched failure-path tests exist.
This is purely a test-clarity nit; behavior is still correctly asserted.

425-448: Existing reducer “should raise” test no longer exercises a failing caseIn
TestValidateNoTimeInjectionForReducer.test_reducer_context_with_time_raises, the docstring says “Reducer context with time injection should raise”, but the current body only constructs valid contexts (now=Nonefor a REDUCER) and asserts that validation passes. The invalidctxwith time and ORCHESTRATOR node_kind is created but never used.Given the stronger negative-path coverage you’ve added in
TestDispatchContextEnforcerErrorCases, this older test is now misleading. Consider either:
- Renaming the test/docstring to reflect the “valid context passes” behavior, or
- Reworking it to actually construct an invalid reducer context (e.g., via
MagicMocklike in the new tests) and assert that validation fails.This is not a blocker, but cleaning it up would reduce confusion for future readers.

PROJECTION is only valid in EnumNodeOutputType for REDUCER nodes - never use PROJECTION for message routing
Propagate correlation_id from incoming requests to error context, auto-generate UUID4 if not present
NEVER include passwords, API keys, tokens, secrets, full connection strings, PII, internal IPs, private keys, or session tokens in error messages or context
Safe to include in errors: service names, operation names, correlation IDs, error codes, sanitized hostnames, ports, retry counts, timeout values, resource identifiers
Use ProtocolConfigurationError for config validation failures, SecretResolutionError for secret/credential resolution, InfraConnectionError for connection failures, InfraTimeoutError for timeouts, InfraAuthenticationError for auth/authz failures, InfraUnavailableError for resource unavailable
InfraConnectionError automatically selects appropriate error code based on context.transport_type (DATABASE, HTTP, GRPC, KAFKA, CONSUL, VAULT, VALKEY)
All infrastructure adapters and services should use MixinAsyncCircuitBreaker for fault tolerance with configurable failure thresholds and reset timeouts

docs/design/ADR_DISPATCHER_TYPE_SAFETY.md (1)
175-244: ADR aligns well with implemented registration-time caching approachThe Option 3 / Phase 1 description (DispatchEntryInternal.accepts_context, registration-time inspection, and dispatch-time usage of the cached flag) matches the behavior exercised in the new tests and keeps the public API stable. The deprecation note for
_dispatcher_accepts_contextis also clear about its continued compatibility role. No changes needed from a runtime or type-safety perspective.Also applies to: 384-414
tests/unit/runtime/test_message_dispatch_engine.py (1)
3256-3971: Context-aware dispatch tests comprehensively exercise time-injection and correlation rulesThe new
TestContextAwareDispatchand concurrency-related scenarios do a good job of pinning down the node_kind→time-injection matrix (REDUCER/COMPUTE:now is None; ORCHESTRATOR/EFFECT/RUNTIME_HOST:nowset near dispatch time), backward-compat behavior for single-parameter dispatchers, and context propagation (correlation_id/trace_id) for both sync and async handlers. The use of UTC-aware timestamps and bounded deltas arounddatetime.now(UTC)should keep these tests stable in CI. No changes needed here.src/omnibase_infra/validation/infra_validators.py (1)
330-353: Infra validation defaults correctly centralized via new constantsBumping
INFRA_MAX_UNIONSto 491 and introducingINFRA_MAX_VIOLATIONS,INFRA_PATTERNS_STRICT, andINFRA_UNIONS_STRICTas the single sources of truth for default behavior cleans up the API nicely. The wrappers (validate_infra_architecture,validate_infra_union_usage,validate_infra_all) now clearly encode “strict by default” semantics, and the updated comments document the current baseline and target well. Implementation and exports look consistent with the updated tests.Also applies to: 355-372, 617-645, 769-782
src/omnibase_infra/runtime/dispatch_context_enforcer.py (4)
109-211: LGTM! Well-structured node_kind-based context factory.The method correctly implements ONEX time injection rules:
- REDUCER/COMPUTE: deterministic (no time)
- ORCHESTRATOR/EFFECT/RUNTIME_HOST: non-deterministic (with time)
The error handling for unrecognized node_kind correctly uses
INTERNAL_ERRORsince this represents a missing switch case rather than a validation failure.Minor observation: The explicit
ifchain (rather than a match statement) is appropriate here for Python 3.9 compatibility, though Python 3.10+matchcould provide exhaustiveness checking.
213-253: Clean delegation pattern for dispatcher-based context creation.The public wrapper correctly extracts
node_kindanddispatcher_idfrom theProtocolMessageDispatcherand delegates to the corecreate_context_for_node_kindmethod. This maintains a single source of truth for context creation logic.
255-352: Validation methods provide explicit checkpoints for architectural invariants.The three validation methods correctly enforce that deterministic nodes (REDUCER/COMPUTE) never receive time injection. The error messages are clear and include the architectural violation context.
354-419: Helper predicates are correct and symmetrical.
requires_time_injectionandforbids_time_injectioncorrectly partition the five node kinds into two groups. Usingsetmembership is efficient for these checks.src/omnibase_infra/runtime/message_dispatch_engine.py (8)
270-289: Well-defined type aliases for context-aware dispatchers.The type aliases clearly distinguish between envelope-only dispatchers (
DispatcherFunc) and context-aware dispatchers (ContextAwareDispatcherFunc). UsingModelEventEnvelope[object]satisfies the no-Any-types coding guideline.
292-338: Efficient slot-based extension for context metadata.The
__slots__extension properly includes the new attributes. Cachingaccepts_contextat registration time is a good optimization that avoids expensiveinspect.signature()calls on every dispatch.
577-601: Type-safe overloads for dispatcher registration.The overload stubs correctly distinguish between:
- No
node_kind→DispatcherFunc(envelope only)- With
node_kind→ContextAwareDispatcherFunc(envelope + context)This enables static type checkers to validate dispatcher signatures match the registration pattern.
603-731: Registration implementation correctly integrates node_kind.The implementation properly:
- Validates inputs before acquiring the lock
- Computes
accepts_contextonce at registration time (cached)- Stores both
node_kindandaccepts_contextin the entry- Includes
node_kindin debug logs
487-489: Context enforcer correctly instantiated as engine dependency.Creating the
DispatchContextEnforcerin__init__follows dependency injection principles and ensures a single source of truth for time injection rules across the engine.
1476-1524: Context injection logic is correct and optimized.The implementation correctly:
- Creates context only when both conditions are met (
node_kindset ANDaccepts_context)- Handles both async and sync dispatcher paths
- Uses appropriate type casts after runtime type narrowing
The optimization to skip context creation when the dispatcher doesn't accept it is a good performance consideration for the dispatch hot path.
1526-1591: Correct delegation to context enforcer with defensive validation.The method properly validates the precondition (
node_kind is not None) and delegates to the centralizedDispatchContextEnforcer. TheINTERNAL_ERRORcode is appropriate since callers should ensurenode_kindis set before calling.
1593-1672: Warning logs unconditionally for all dispatchers, not just those withnode_kindset.The implementation is correct but the original review's characterization was inaccurate. The warning at lines 1653-1660 fires whenever a dispatcher has 2+ parameters and the second parameter doesn't follow context naming conventions—regardless of whether
node_kindis set. The_dispatcher_accepts_context()method receives nonode_kindcontext and performs the warning check unconditionally during registration.While this may appear noisy for dispatchers without
node_kind(which never receive context at runtime per line 1484), the warning's unconditional firing during registration is acceptable since it aids developers in identifying potential signature mismatches and occurs only once per dispatcher registration, not at dispatch time.

src/omnibase_infra/runtime/message_dispatch_engine.py (1)
1595-1674: Consider using >= 2 check without the naming convention warning for flexibility.The signature inspection logic is sound. However, the warning at lines 1653-1663 about unconventional parameter naming may produce false positives for legitimate dispatchers with different naming conventions (e.g.,
envelope, dispatch_ctxorenvelope, ctx_dispatch).While "ctx" is checked, other valid patterns like
dispatch_context→ contains "context" ✓, butenv_ctx→ contains "ctx" ✓ would pass. The warning is non-blocking which is good, but consider whether it adds more noise than value in practice.🔎 Optional: Make the naming check more lenient or configurable
If false positive warnings become noisy, consider:
- Adding more common patterns:
"context","ctx","disp_ctx","dispatch_ctx"- Making the warning configurable via a constructor parameter
- Checking the type annotation instead of the name (if available)
# Example: Check type annotation if available if second_param.annotation is not inspect.Parameter.empty: annotation_str = str(second_param.annotation) if "DispatchContext" in annotation_str or "ModelDispatchContext" in annotation_str: return True # Skip warning, type annotation is correcttests/unit/models/registration/test_model_node_introspection_event.py (1)

43-56: LGTM! Threshold documentation and assertion updated correctly.The docstring and assertion are correctly updated to reflect the new
INFRA_MAX_UNIONSvalue of 515, with clear threshold history documenting the OMN-990 dispatcher unions addition.
244-246: LGTM! Comment clarified.The comment now clearly indicates the default comes from the constant.
487-515: LGTM! Regression guard test with updated documentation.The test provides effective regression protection for union count thresholds, and the updated documentation accurately reflects the new baseline and target.
src/omnibase_infra/validation/infra_validators.py (2)
326-341: LGTM! INFRA_MAX_UNIONS updated with clear rationale.The constant is updated to 515 with well-documented threshold history explaining the OMN-990 MessageDispatchEngine integration that added ~22 unions for dispatcher protocols, context enforcement, and envelope typing patterns. The migration target (<200 via JsonValue migration) is clearly stated.
621-641: LGTM! Function signature and documentation are clear.The
validate_infra_union_usagefunction correctly uses the updatedINFRA_MAX_UNIONSconstant as the default, and the docstring accurately describes the parameters.src/omnibase_infra/runtime/runtime_host_process.py (3)
45-46: LGTM - Import addition for Pydantic model support.The
BaseModelimport is correctly placed and supports the new envelope serialization capability.
1069-1093: LGTM - Clean Pydantic model serialization support.The implementation correctly:
- Checks for
BaseModelinstance before callingmodel_dump()- Preserves the recursive UUID conversion logic
- Handles nested UUIDs within Pydantic models via the existing
convert_valuetraversalThe type annotation
JsonValue | BaseModelaccurately reflects the accepted input types.
1095-1109: LGTM - Unified serialization path.The method correctly routes both dict envelopes and Pydantic models through
_serialize_envelope, ensuring consistent UUID-to-string conversion before publishing.src/omnibase_infra/runtime/message_dispatch_engine.py (9)
140-152: LGTM - Proper TYPE_CHECKING guard for EnumNodeKind.The
EnumNodeKindimport is correctly placed underTYPE_CHECKINGto avoid runtime import overhead while maintaining type safety. TheDispatchContextEnforcerimport at runtime is appropriate since it's instantiated in__init__.
272-292: LGTM - Well-documented context-aware dispatcher types.The type aliases clearly document the time injection semantics and provide proper type safety for context-aware dispatchers. The sync variant
_SyncContextAwareDispatcherFuncappropriately mirrors the async type for executor-based execution.
294-341: LGTM - Clean extension of DispatchEntryInternal.The
__slots__are properly updated and alphabetically sorted. The docstring clearly documents the ONEX time injection semantics for each node kind. Storingaccepts_contextat registration time avoids repeated signature inspection during dispatch.
489-517: LGTM - DispatchContextEnforcer integration and deprecation notice.The context enforcer is correctly instantiated once per engine instance. The deprecation notice for the legacy
_metricsdict is thorough and provides clear migration guidance.
579-612: LGTM - Type-safe overloads for register_dispatcher.The overloads correctly distinguish between:
node_kind=None→DispatcherFunc(no context)node_kind: EnumNodeKind→ContextAwareDispatcherFunc(receives context)The keyword-only
*in the second overload enforces explicitnode_kindusage when registering context-aware dispatchers.
709-733: LGTM - Registration-time caching of accepts_context.Caching the signature inspection result at registration time is a good performance optimization that avoids repeated
inspect.signature()calls on the hot dispatch path. The debug log now includesnode_kindfor observability.
1478-1526: LGTM - Context injection logic in _execute_dispatcher.The implementation correctly:
- Only creates context when both
node_kindis set AND dispatcher accepts context- Handles both async and sync dispatchers with context
- Uses proper type casts for the sync executor path
The comment about avoiding unnecessary object creation on the hot path is helpful.
1528-1593: LGTM - Clean delegation to DispatchContextEnforcer.The
_create_context_for_entrymethod properly validatesnode_kindbefore delegation and provides comprehensive documentation of time semantics. The version changelog annotations are helpful for tracking API evolution.
1857-1872: LGTM - Legacy alias updated for consistency.The
register_handlermethod correctly propagates the newnode_kindparameter toregister_dispatcher, maintaining backwards compatibility while enabling context-aware handlers via the legacy API.tests/unit/models/registration/test_model_node_introspection_event.py (1)
35-49: Excellent comprehensive test coverage for correlation_id field.The integration of
correlation_idacross all test cases is thorough and consistent. The tests properly verify:
- UUID type validation
- Value preservation through instantiation
- Serialization/deserialization roundtrip
- Immutability (frozen model behavior)
- Equality comparisons
- from_attributes pattern support
- model_copy operations
The changes align with the PR objectives for correlation ID propagation and follow established test patterns for UUID fields.
Based on learnings, correlation_id propagation for end-to-end traceability is properly tested.

140-152: LGTM: Clean import organization with TYPE_CHECKING for circular import prevention.The import changes are well-structured:
overloadenables type-safe dispatcher registration variantsDispatchContextEnforcerimport for context creation delegationEnumNodeKindin TYPE_CHECKING block avoids circular imports while enabling type hintsThe runtime import of
EnumNodeKindat Line 706 correctly handles the validation path.
246-251: LGTM: Well-documented threshold constant with clear extensibility rationale.The
MIN_PARAMS_FOR_CONTEXTconstant is properly documented and the decision to use>=instead of==for future extensibility is sound. This allows dispatchers with optional additional parameters to be context-aware.
279-298: LGTM: Context-aware dispatcher types follow established patterns.The new type aliases are consistent with existing
DispatcherFuncand_SyncDispatcherFuncpatterns. Documentation clearly explains the time injection semantics per node kind, and the private_Syncvariant correctly supports type narrowing for thread pool execution.
324-347: LGTM: Clean extension of DispatchEntryInternal with performance optimization.The addition of
node_kindandaccepts_contextfields toDispatchEntryInternalis well-designed:
__slots__kept alphabetically ordered for maintainabilityaccepts_contextcached at registration time avoids expensiveinspect.signature()calls on hot dispatch path- Default values maintain backwards compatibility
496-498: LGTM: Clean delegation to DispatchContextEnforcer for single source of truth.Initializing
_context_enforceras an instance field properly delegates time injection rule enforcement to a centralized component, following the single responsibility principle.
586-619: LGTM: Type-safe overloads enforce correct dispatcher signatures based on node_kind.The overload pattern is well-designed:
- First overload:
node_kind=None→ expectsDispatcherFunc(single parameter)- Second overload:
node_kindrequired → expectsContextAwareDispatcherFunc(two parameters)This provides compile-time type safety to prevent signature mismatches while maintaining backwards compatibility.
728-730: LGTM: Smart performance optimization with registration-time signature inspection caching.Computing
accepts_contextonce at registration time and caching it inDispatchEntryInternalis the correct approach. This avoids expensiveinspect.signature()calls on the hot dispatch path, where performance is critical.
1499-1545: LGTM: Efficient context creation with proper async/sync handling.The context creation logic is well-optimized:
- Context created only when both
node_kindis set ANDaccepts_contextis True- Properly handles both async and sync dispatchers with and without context
- Type casts are safe after
iscoroutinefunctioncheck- Comments clearly explain the optimization rationale
1547-1612: LGTM: Clean delegation to DispatchContextEnforcer with comprehensive documentation.The
_create_context_for_entry()method properly:
- Validates
node_kindis not None before delegation- Delegates to
DispatchContextEnforcerfor single source of truth- Documents time semantics (context creation at dispatch time, not execution time)
- Raises
INTERNAL_ERRORif called with None (correct error code for internal contract violation)
1614-1694: LGTM: Robust signature inspection with helpful developer warnings.The
_dispatcher_accepts_context()method is well-implemented:
- Correctly uses
inspect.signature()and checks parameter count- Warning for unconventional parameter naming (lines 1664-1683) is non-blocking and helpful for type safety
- Graceful handling of uninspectable signatures (C extensions, decorators) with fallback to False
- Clear logging explains why dispatchers might not receive context
The approach balances strictness (for code quality) with flexibility (for backwards compatibility).

Fix exemption rationale to match actual method signatures.
The exemption rationales list parameters that don't match the actual method signatures in message_dispatch_engine.py:
-
init exemption (lines 210-216): Lists 6 parameters (
context_enforcer, topic_parser, default_node_kind, logger, topic_to_dispatcher_map, category_dispatchers), but the actual__init__method (lines 446-449) only acceptsloggerparameter. -
register_dispatcher exemption (lines 217-223): Lists
topic_patternsandpriorityparameters, but the actual method signature (lines 612-619) takesdispatcher_id, dispatcher, category, message_types, node_kind(notopic_patternsorpriority). -
register_handler exemption (lines 224-230): Same issue—lists
topic_patternsandpriority, but actual signature (lines 1877-1884) takeshandler_id, handler, category, message_types, node_kind.

210-230, the exemption "reason" texts list parameter names that do not match the
actual method signatures in message_dispatch_engine.py; update each rationale to
reflect the real parameters: for Function '__init__' replace the listed
parameters with the single actual parameter 'logger' (and note any other
contextual dependencies if needed), for Function 'register_dispatcher' replace
the listed parameters with 'dispatcher_id, dispatcher, category, message_types,
node_kind', and for Function 'register_handler' replace the listed parameters
with 'handler_id, handler, category, message_types, node_kind' (and mark
register_handler as deprecated in favor of register_dispatcher if you want to
keep that note). Ensure the ticket OMN-990 remains, keep wording concise and
accurate, and run a quick grep/inspect to confirm names match the source line
references before committing.

🎯 Minor Suggestions (Non-Blocking)1. Consider Named Constant for Parameter Validation# Current (line ~250):
MIN_PARAMS_FOR_CONTEXT = 2
# Suggestion: Add validation constant for parameter name patterns
CONTEXT_PARAM_PATTERNS = ("context", "ctx") # For warning logicRationale: Currently the parameter name check uses inline string literals. Extracting to a constant improves maintainability. Impact: Low - current implementation is fine, just a polish opportunity. 2. Union Threshold GrowthThe Current trajectory:
Recommendation: Continue Impact: Low - threshold increase is justified and documented. 3. Validation Exemptions DocumentationThe PR adds __init__ (7 params): central coordinator configuration
register_dispatcher (6 params): routing configuration
register_handler (6 params): backwards compatibilityObservation: The exemptions follow the same pattern as other infrastructure coordinators (RuntimeHostProcess, KafkaEventBus). Suggestion: Consider whether Impact: Low - exemptions are appropriate for infrastructure coordinators. 🚀 Performance ConsiderationsExcellent Optimizations ✅

425-448:test_reducer_context_with_time_raisesdoes not exercise the failure path it describesThis existing test’s name/docstring say “Reducer context with time injection should raise”, but the body only validates a valid reducer context (
now=None) and never calls the enforcer with a reducer that has time set. The locally constructedctxwithnow=datetime.now(UTC)is also unused. Consider either:
- Renaming the test to reflect that it’s a “valid reducer context passes” case, or
- Updating it to construct a deliberately invalid reducer context (e.g., via
MagicMockas in the new error‑case tests) and assert thatvalidate_no_time_injection_for_reducerraisesModelOnexErrorwithVALIDATION_FAILED.Right now the test is misleading and redundant with the newer coverage below.

210-230: Fix exemption rationales to match actual method signatures.The exemption rationales still list parameters that don't match the actual method signatures in

This affects maintainability since future developers reading these rationales may be confused about the actual method signatures.Please apply the fix suggested in the previous review to ensure the documented parameters match the actual implementation.

1069-1093: LGTM! Clean implementation of BaseModel support.The BaseModel-to-dict conversion is correctly handled before UUID serialization. The implementation is straightforward and maintains consistency with the existing UUID conversion pattern.
Optional: Consider Pydantic's JSON serialization mode
You could optionally use
model_dump(mode='json')to leverage Pydantic's built-in JSON serialization, which handles UUIDs automatically. However, the current explicit approach is clear and works well with the existingconvert_valuetraversal pattern:# Convert Pydantic models to dict first if isinstance(envelope, BaseModel): - envelope = envelope.model_dump() + envelope = envelope.model_dump(mode='json')This is entirely optional—the current implementation is perfectly valid.

152-160: Confirmhas_time_injectionis a bool property, not a methodThese assertions treat
ModelDispatchContext.has_time_injectionas a boolean attribute. If it is implemented as a method (def has_time_injection(self) -> bool:) rather than a@property/field, these checks will compare against the function object and always fail. Please double‑check the model and either keep it as a property or update tests to callhas_time_injection().tests/unit/runtime/test_message_dispatch_engine.py (1)
4019-4362: Signature‑inspection tests give strong coverage but rely on specific log text
TestDispatcherSignatureInspectionthoroughly covers ≥2‑parameter detection, both ValueError/TypeError inspection failures, and unconventional parameter naming. The only caution is that several tests assert on full warning message substrings ("Failed to inspect dispatcher signature","context naming convention", etc.), which makes refactors of log wording slightly painful even when behavior is unchanged. If you expect log text to evolve, you could loosen these to key tokens (e.g., dispatcher name +"Uninspectable dispatchers") and avoid over‑specifying prose.

src/omnibase_infra/validation/infra_validators.py (4)
330-340: LGTM! Threshold increase is well-documented.The union count baseline increase from 485 to 515 (+30) is properly documented with clear reasoning (OMN-990 MessageDispatchEngine + OMN-947 snapshots adding ~24 unions). The comment correctly notes these are mostly legitimate
X | Nonenullable patterns and includes the migration target (<200 via dict[str, object] → JsonValue).
342-356: LGTM! Strict governance constants enable zero-tolerance validation.The new constants (INFRA_MAX_VIOLATIONS = 0, INFRA_PATTERNS_STRICT = True, INFRA_UNIONS_STRICT = True) establish clear strict-mode defaults. The comments explain their purpose and enforcement behavior, aligning with the PR objective of stricter architecture compliance for infrastructure nodes.
358-374: LGTM! Function signature updated consistently with new constant.The addition of the
max_violations: int = INFRA_MAX_VIOLATIONSparameter with default value 0 enables strict one-model-per-file enforcement while maintaining backward compatibility. The docstring is updated to reflect the new parameter and default behavior.
620-658: LGTM! Docstring accurately reflects the parameter defaults.The docstring update on line 639 correctly documents that
max_unionsdefaults toINFRA_MAX_UNIONS, maintaining consistency with the actual function signature and the new governance constants pattern.src/omnibase_infra/runtime/runtime_host_process.py (2)
45-45: LGTM! Clean import addition.The BaseModel import is appropriate for the new envelope serialization capability.
1095-1110: LGTM! Signature change aligns with serialization support.The method signature correctly extends to accept BaseModel instances, with the implementation properly delegating to the updated
_serialize_envelopefor conversion before publishing.tests/unit/runtime/test_dispatch_context_integration.py (2)
567-629: Time‑injection matrix coverage looks solid and future‑proofThe parametrized
TestAllNodeKindsTimeInjectionMatrix.test_node_kind_time_injection_matrixcleanly encodes the ONEX rules for all node kinds and will quickly surface regressions if new logic accidentally injectsnowinto deterministic nodes or omits it where required. No changes needed here.
824-920: Uninspectable dispatcher tests accurately lock in fallback behaviorThe
TestUninspectableDispatcherFallbackscenarios (custom__signature__raising and the__call__arity checks) map well to the documented_dispatcher_accepts_contextbehavior and ensure uninspectable dispatchers are still usable and only receive the envelope. This is a good, realistic regression‑guard for the signature‑inspection logic.tests/unit/runtime/test_message_dispatch_engine.py (1)
3251-4012: Context‑aware dispatch tests correctly exercise node‑kind + context semanticsThe
TestContextAwareDispatchblock does a good job validating the new behavior end‑to‑end:
- Internal error path for
_create_context_for_entrywithnode_kind=None- Deterministic nodes (REDUCER/COMPUTE) never getting
now, including sync/async dispatchers- Time‑injected nodes (ORCHESTRATOR/EFFECT/RUNTIME_HOST) getting a bounded
nowand having context passed to sync handlers viarun_in_executor- Backwards‑compat for single‑param dispatchers and correlation/trace propagation (including auto‑generation when missing).
The coverage matches the PR’s architectural description and should catch most regressions in the engine/enforcer wiring.
tests/unit/runtime/test_dispatch_context_enforcer.py (2)
1024-1296: Error‑case tests align well withDispatchContextEnforcerbehaviorThe
TestDispatchContextEnforcerErrorCasesclass cleanly codifies the intended behavior:
- Unrecognized
node_kindyieldsModelOnexErrorwithINTERNAL_ERRORand a message containingdispatcher_id.- Deterministic nodes (REDUCER/COMPUTE) with time injection cause
VALIDATION_FAILED, including via the generic deterministic validator.- Non‑deterministic node kinds with time injection are explicitly allowed, and error messages surface the actual
nowvalue.This is consistent with the enforcer’s contract and the broader OMN‑973/OMN‑990 rationale.
1304-1434: Missing‑correlation‑id behavior tests match tracing guidelines
TestMissingCorrelationIdBehaviornicely encodes the tracing contract: auto‑generate a UUID correlation_id when the envelope omits one, do so consistently across all node kinds, ensure uniqueness across calls, and never overwrite a provided ID. This directly backs the correlation_id propagation requirements in the coding guidelines.
