feat(runtime): enforce time injection context at dispatch [OMN-973] - #66
jonahgabriel merged 11 commits into
Conversation
Implement runtime dispatch enforcement for time injection context models. Reducers must NEVER receive `now`, orchestrators/effects must receive it. ## Changes ### New Models - `ModelDispatchContext`: Pydantic model with factory methods enforcing time injection rules per node kind (for_reducer, for_orchestrator, for_effect) - Model validator rejects reducer contexts with time injection at construction ### New Runtime Components - `DispatchContextEnforcer`: Creates appropriate context based on dispatcher's node_kind, injecting time only for orchestrator/effect nodes ### ONEX Architectural Rules Enforced | Node Kind | Time Injection | Rationale | |---------------|----------------|----------------------------------------| | REDUCER | FORBIDDEN | Must be deterministic for event replay | | COMPUTE | FORBIDDEN | Pure transformations, no side effects | | ORCHESTRATOR | REQUIRED | Needs time for deadlines/timeouts | | EFFECT | REQUIRED | Needs time for retries/metrics | ## Test Coverage - 43 unit tests for dispatch context enforcer - 32 integration tests for full dispatch flow - All 75 tests passing Acceptance Criteria: - [x] Runtime dispatch enforces context type - [x] Tests proving reducers cannot access `now` via runtime dispatch - [x] Integration tests for context injection at dispatch time
WalkthroughAdds an immutable ModelDispatchContext and a DispatchContextEnforcer to enforce ONEX time-injection rules per node kind, consolidates JsonValue imports, updates infra validation constants, and adds comprehensive unit and integration tests for dispatch context behavior. Changes

Potential Issues1. Minor: Inconsistent Factory Usage for COMPUTE NodesLocation: dispatch_context_enforcer.py:158-165 Issue: COMPUTE nodes use direct construction instead of a factory method, while REDUCER nodes use for_reducer() factory. Recommendation: Consider adding ModelDispatchContext.for_compute() factory method for consistency. This would:
Severity: Low (nice-to-have, not blocking) 2. Minor: RUNTIME_HOST Also Uses Direct ConstructionLocation: dispatch_context_enforcer.py:181-188 Issue: Same as above - RUNTIME_HOST uses direct construction instead of a factory. Recommendation: Consider ModelDispatchContext.for_runtime_host() factory. Severity: Low (nice-to-have, not blocking) 3. Documentation: Missing for_compute() Factory NoteLocation: model_dispatch_context.py:23-26 Issue: Module docstring mentions factory methods but does not list for_compute() (because it does not exist yet).

Recommendations for Future Work1. Add Factory Methods for COMPUTE and RUNTIME_HOSTFor consistency and discoverability, consider adding for_compute() and for_runtime_host() factory methods to match the pattern established by for_reducer(), for_orchestrator(), and for_effect(). 2. Integration with MessageDispatchEngineEnsure the MessageDispatchEngine uses DispatchContextEnforcer.create_context_for_dispatcher() before invoking dispatchers. This would complete the integration (likely already done in another PR/ticket). Final VerdictAPPROVED - This PR is ready to merge. Summary

💡 Recommendations (Non-Blocking)
1. Documentation Consistency
File: model_dispatch_context.py:9-10
Add COMPUTE node to module docstring for completeness:
# Current:
- **Reducers** (pure state aggregators) must NEVER receive `now`
- **Orchestrators** and **Effects** CAN receive `now`
# Suggested:
- **Reducers** and **Compute** nodes (pure/deterministic) must NEVER receive `now`
- **Orchestrators**, **Effects**, and **Runtime Hosts** CAN receive `now`2. Consider Return Type Clarification
File: model_dispatch_context.py:178
For maximum clarity, consider -> Literal[True] to signal "always True or raises":
from typing import Literal
def validate_for_node_kind(self) -> Literal[True]:
"""..."""This is a minor style choice; current pattern is also valid.
3. Consider Timestamp Injection Point Documentation
File: dispatch_context_enforcer.py:168
Add comment clarifying when timestamp is captured:
if node_kind == EnumNodeKind.ORCHESTRATOR:
# Timestamp captured at context creation (dispatch time)
# Drift from actual handler execution is microseconds in practice
return ModelDispatchContext.for_orchestrator(
correlation_id=correlation_id,
trace_id=trace_id,
now=datetime.now(UTC), # Captured here
)📊 Impact Assessment
Positive Impact:
- ✅ Enforces critical ONEX architectural invariant (reducer determinism)
- ✅ Prevents accidental time-dependent code in reducers (event replay safety)
- ✅ Type-safe factory pattern prevents misuse at development time
- ✅ Clear error messages aid debugging when violations occur
- ✅ No breaking changes to existing code
Risk:
⚠️ Low: New validation could catch existing violations if reducers were accidentally receivingnow- Mitigation: Tests prove this works correctly; existing code should be validated
🎓 Learning Opportunities
This PR demonstrates excellent software engineering practices:
- Defense in depth: Multiple validation layers (model validator + explicit method + enforcer)
- Immutability: Frozen Pydantic models prevent state mutation bugs
- Factory pattern: Enforces invariants through API design rather than runtime checks
- Comprehensive testing: Unit + integration + replay determinism tests
- Clear documentation: Rationale and examples aid future maintainers
Final Verdict
✅ APPROVED
This PR successfully implements time injection enforcement with:
- Strong architectural correctness
- Excellent test coverage (75 tests, all passing)
- Clean, maintainable code following ONEX patterns
- Comprehensive documentation
- No security or performance concerns
The minor recommendations above are stylistic improvements, not blockers. The implementation is production-ready.
Great work on OMN-973! This is a critical piece of infrastructure for ONEX runtime correctness.

In distributed ONEX deployments with Kafka, the time between dispatch context creation and handler execution could be seconds or minutes due to:
Recommendation:

validate_no_time_injection_for_compute() # Lines 226-256
validate_no_time_injection_for_deterministic_node() # Lines 258-291Problem: Code duplication and unclear API surface. When should I call Recommendation: Consider consolidating to a single method: def validate_no_time_injection(
self,

) -> None:
"""Validate that deterministic nodes don't have time injection.
Raises:
ModelOnexError: If REDUCER or COMPUTE node has time injection.

🔍 Code Quality ObservationsMinor Suggestions (Non-blocking)1. Validation Method RedundancyThe enforcer has three similar validation methods:
Observation: The third method ( Counter-argument: Having specific methods improves error messages and intent clarity. Current approach is defensible. 2. Error Code Consistency
When an unknown Suggestion: Consider using # Current:
raise ModelOnexError(
message=f"Unknown node_kind '{node_kind}' ...",
error_code=EnumCoreErrorCode.VALIDATION_FAILED, # Is this a validation failure or internal error?
)3. Correlation ID Generation Timing
correlation_id = envelope.correlation_id or uuid4()Observation: UUID generation happens unconditionally, even when Optimization (micro-optimization, not critical): correlation_id = envelope.correlation_id if envelope.correlation_id is not None else uuid4()However, the current approach is more readable and the performance impact is negligible. Not worth changing unless you're optimizing hot paths. 4. Timestamp Drift Comment
# Timestamp captured at context creation (dispatch time).

The handle method signature does not match ProtocolMessageDispatcher.
The protocol requires handle(self, envelope: ModelEventEnvelope[object]) -> ModelDispatchResult, but the test implementation uses envelope: object and adds an extra context parameter. The envelope parameter must be ModelEventEnvelope[object] per coding guidelines for dispatcher parameters. This signature mismatch prevents the test double from being protocol-compliant and won't accurately verify the dispatch engine's behavior.

134 to 150, the test handler's signature is not protocol-compliant: change the
method to match ProtocolMessageDispatcher by defining handle(self, envelope:
ModelEventEnvelope[object]) -> ModelDispatchResult (remove the extra context
param), update captured_envelope to store the received ModelEventEnvelope, and
if you need the context for assertions extract and store envelope.context into
captured_context; ensure type annotations/imports for ModelEventEnvelope are
present.

Test name and implementation mismatch.
The test test_reducer_context_with_time_raises suggests it should verify that a reducer context with time injection raises an error. However, the test creates a valid reducer context with now=None and asserts it passes validation. The test name and docstring indicate testing for rejection, but the implementation tests for acceptance.
🔎 Consider renaming or restructuring this test
The test's intent seems to be demonstrating that invalid reducer contexts can't be created due to the Pydantic validator. The actual assertion (line 447) validates a valid context. Consider:
- Rename to
test_valid_reducer_context_passes_validation - Or add a comment clarifying that the Pydantic validator prevents invalid state construction
- def test_reducer_context_with_time_raises(
+ def test_reducer_context_pydantic_prevents_invalid_state(

In tests/unit/runtime/test_dispatch_context_enforcer.py around lines 425-447,
the test named test_reducer_context_with_time_raises is inconsistent: it
documents expecting a reducer-with-time to raise but constructs a valid reducer
(now=None) and asserts it passes; either rename the test to
test_valid_reducer_context_passes_validation and update docstring to reflect
that it verifies a valid reducer context is accepted, or modify the test to
actually construct an invalid reducer context (e.g., create a reducer
ModelDispatchContext that includes a non-None now via bypassing validation) and
assert enforcer.validate_no_time_injection_for_reducer raises the expected
exception; update the test name and docstring accordingly to match the chosen
behavior.
Merge main branch which enabled strict validation mode (OMN-983). Resolution: - Keep INFRA_MAX_UNIONS = 465 (current baseline after OMN-937/OMN-973) - Adopt INFRA_PATTERNS_STRICT = True (strict mode from main) - Adopt INFRA_UNIONS_STRICT = True (strict mode from main) - Update test expectations to match Validation results: - Union count: 415 (well under 465 threshold) - All 5 validators: PASS

Fix the outdated baseline and address the exceeded union threshold.
The documented baseline of 462 unions is incorrect—the actual count is 657 unions, exceeding the threshold of 465 by 192 unions. The constant and documentation (lines 330-337 and 636) must be updated to reflect the current state. Additionally, either enforce the 465 limit through validation or increase the threshold explicitly if the higher count is intentional. The current disconnect between documented and actual values creates confusion about code quality expectations.

In src/omnibase_infra/validation/infra_validators.py around lines 330-337 and
also update the related comment at line ~636, the annotated baseline (462
unions) and INFRA_MAX_UNIONS = 465 are stale—the actual union count is 657;
update the comment text to reflect the current measured count and change
INFRA_MAX_UNIONS to the intended threshold (either set to 657 if you want the
constant to match current state or increase it to a documented new limit), and
then add/enable enforcement: ensure the validator compares the measured union
count to INFRA_MAX_UNIONS and fails CI (raise an exception or return a non-zero
error) when exceeded, or if the higher count is intentional, add a short
rationale comment and update both places to the new threshold to avoid
confusion.
