ChangesPuzzletron orchestration
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟡 Moderate · up to The PR strengthens orchestration identity and recovery, but a hung post-MIP aggregation can still stall campaign progress, while malformed finalization data may be treated as current. These bounded availability and correctness risks should be fixed or explicitly accepted before merge. Sequence Diagram(s)sequenceDiagram

Reject manifests that do not contain a report.
isinstance(outputs, Mapping) accepts {}. If the summary file contains JSON null, summary == outputs.get("report") is true. The function can then accept a finalization marker for a successful manifest with no report.
Require the report key before comparing the values. Add a missing-report case to tests/unit/torch/puzzletron/test_width_scenarios.py.

What does this PR do?
Puzzletron decides whether persisted orchestration work is reusable from manifests, attempts, artifacts, and post-MIP records that do not share a reliable identity. When configuration or execution context changes, stale results can therefore appear current; after a restart, artifact settling can start over.
This PR ties manifests, stage completions, and post-MIP outputs to stable identities for their effective configuration and producer lineage. Recovery reuses records only when they match the current run, rejects inconsistent registries, and preserves the original artifact-settling deadline across restarts.
This is the first in a series of smaller PRs extracted from Add Puzzletron v2 GPU quality baseline.
