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. The diagnostic goal for MILEFFECTSERR_RESERVED is to identify the first rejecting object and transition, not merely the final high-level symptom.
Subsystem boundary
For MILEFFECTSERR_RESERVED, a reserved value provides less public semantic information than the neighboring named graph errors. When MILEFFECTSERR_RESERVED is returned, 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 in the MILEFFECTSERR_RESERVED path.
For MILEFFECTSERR_RESERVED, inspect the following boundary: 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 in the MILEFFECTSERR_RESERVED path. For MILEFFECTSERR_RESERVED, compare public neighboring invariants—ownership, connectors, cycles, transforms, and bounds—but report only observations that the trace actually establishes.
- For MILEFFECTSERR_RESERVED, capture the call stack, build, object graph, and preceding result without assigning an invented meaning.
- When MILEFFECTSERR_RESERVED is returned, rebuild the smallest graph containing only the implicated node and one known input.
- Log ownership changes and graph generation numbers in the MILEFFECTSERR_RESERVED path.
- For MILEFFECTSERR_RESERVED, validate the graph before allocating large intermediate resources.
Facts worth preserving
| Record | Why it matters here |
|---|---|
| Effect instance and owning graph or group identity | Preserving effect instance and owning graph or group identity provides the evidence needed to test this distinction: unlike named graph invariants, a reserved code should not drive code-specific recovery logic. |
| Connector, input, child, listener, property, or transform involved | For MILEFFECTSERR_RESERVED, recording connector, input, child, listener, property, or transform involved separates the a reserved MIL effects status boundary from a later wrapper symptom. |
| Calculated input and output bounds | In MILEFFECTSERR_RESERVED diagnostics, recording calculated input and output bounds ties the HRESULT to the a reserved MIL effects status boundary rather than to the final visible failure. |
| Construction sequence and first method returning the HRESULT | Comparing construction sequence and first method returning the HRESULT shows whether MILEFFECTSERR_RESERVED follows input, object state, or environment. |
What each result would imply
| Test | Interpretation | Hold constant |
|---|---|---|
| Same environment, reduced input | If MILEFFECTSERR_RESERVED disappears with a smaller faithful case, complexity within a reserved MIL effects status is implicated. | For MILEFFECTSERR_RESERVED, keep effect instance and owning graph or group identity fixed while simplifying calculated input and output bounds. |
| Same input, fresh object generation | If MILEFFECTSERR_RESERVED changes after rebuilding state, examine ownership across the effect instance, connector builder, graph owner, listener, and bounds calculator. | For MILEFFECTSERR_RESERVED, place connector, input, child, listener, property, or transform involved on the timeline of the last successful transition. |
| Same operation on a controlled second path | If MILEFFECTSERR_RESERVED follows one environment, the failure is not explained by source data alone. | For MILEFFECTSERR_RESERVED, compare visual generation, effect registration, shader profile, rendering tier, and target dimensions while preserving 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. For MILEFFECTSERR_RESERVED, do not catch the HRESULT and continue rendering with a partially connected graph; later failures can obscure the invariant that was first violated.
Verification after repair
A correction for MILEFFECTSERR_RESERVED should let the operation at the a reserved MIL effects status boundary complete repeatedly under the original supported conditions. Repeat the control that begins with “Capture the call stack, build, object graph, and preceding result without assigning an invented meaning” and confirm that the following lifecycle step also succeeds. For MILEFFECTSERR_RESERVED, keep the original failing sample and one deliberate negative case so fallback cannot be mistaken for repair.
