MILEFFECTSERR_RESERVED
MILEFFECTSERR_RESERVED belongs to a reserved MIL effects status. The MIL effect subsystem returned a reserved status for which no stable public semantic should be assumed.
Subsystem context
A reserved value provides less public semantic information than the neighboring named graph errors. The responsible approach is to preserve the exact numeric HRESULT, OS build, calling operation, graph shape, and any nested status without assigning an undocumented meaning. Future or private implementations can use a reserved slot differently.
the exact internal operation and OS build that emitted the reserved value.
Isolation procedure
Reduce the graph while keeping the same OS build and call boundary. Compare public neighboring invariants—ownership, connectors, cycles, transforms, and bounds—but report only observations that the trace actually establishes.
- Capture the call stack, build, object graph, and preceding result without assigning an invented meaning.
- Rebuild the smallest graph containing only the implicated node and one known input.
- Log ownership changes and graph generation numbers.
- Validate the graph before allocating large intermediate resources.
Evidence to preserve
- Effect instance and owning graph or group identity
- Connector, input, child, listener, property, or transform involved
- Calculated input and output bounds
- Construction sequence and first method returning the HRESULT
Do not hide the original condition
Unlike named graph invariants, a reserved code should not drive code-specific recovery logic. Do not catch the HRESULT and continue rendering with a partially connected graph; later failures can obscure the invariant that was first violated.
