What does this PR do?

Type of change: new feature

Puzzletron previously split operational status and retained evidence across controller state, generated HTML, and report-directory indexes. This change makes an atomic results/result.json the authority for both live progress and completed results, then derives optional HTML and the central discovery catalog from that structured record.

  • Record run status, timing, freshness, DAG stages and attempts, completed and total work, qualified ETA, subjects, evaluator repetitions, decision metrics, artifacts, provenance, and limitations in one versioned schema. Heterogeneous block configurations are stored losslessly in grouped form, while complete producer observations remain linked for drill-down.
  • Finalize structured results before rendering presentation artifacts. results inspect, results export, and results refresh validate or regenerate from the authoritative file, while the report manifest binds the HTML to source and output digests. HTML tables are bounded and no longer embed a second copy of the source result.
  • Replace report-subtree navigation indexes with generated reports/catalog.yaml and use the campaign-reports guide as the human hub. Historical reports remain discoverable with explicit evidence and provenance qualifications.
  • Give launched tasks writable temporary defaults for framework caches while preserving explicit site configuration. The README also directs custom-model users to python examples/puzzletron/puzzletron.py setup --help for setup options.
  • Correct the maintained 0.8B VLM campaign selection metric so it matches the evaluator output.

Testing

Focused regression tests cover result validation and projection, lossless architecture grouping, bounded rendering, catalog generation, controller completion and recovery, detached inspection, CLI behavior, setup entrypoints, and task-cache defaults. A fresh Qwen 3.5 0.8B VLM smoke completed the maintained route without site-specific cache overrides and produced a validated structured result, HTML report, and digest manifest. The full campaign completed its pruning, KD, and frozen downstream evaluations; correcting the selection metric allowed the final selection and result manifest to be regenerated from retained evidence without repeating model work.

📝 Walkthrough

Walkthrough

Changes

The PR adds structured Puzzletron result validation, publication, rendering, catalog generation, CLI operations, historical records, task-local runtime caches, and updated documentation.

Structured Puzzletron results

Layer / File(s) Summary
Structured result contract and rendering
modelopt/torch/puzzletron/orchestration/run_reporting.py, modelopt/torch/puzzletron/orchestration/result_render.py, tests/unit/torch/puzzletron/test_run_results.py
Structured results support validation, atomic persistence, inspection, export, text rendering, HTML refresh, evidence projection, metric comparison, and bounded output.
Catalog generation and historical records
modelopt/torch/puzzletron/orchestration/result_catalog.py, examples/puzzletron/generate_results_catalog.py, examples/puzzletron/reports/catalog.yaml, examples/puzzletron/reports/legacy/**, tests/unit/torch/puzzletron/test_result_catalog.py
The catalog discovers current and qualified historical records, validates metadata, computes digests, and renders deterministic YAML.
Orchestration and CLI integration
modelopt/torch/puzzletron/orchestration/controller.py, modelopt/torch/puzzletron/orchestration/reporting.py, modelopt/torch/puzzletron/orchestration/reusable_allocation.py, examples/puzzletron/puzzletron.py, examples/puzzletron/orchestrate.py, tests/unit/torch/puzzletron/test_orchestration_*.py
The controller publishes structured progress and final results without executor-based final-report jobs. The CLI supports inspect, export, and refresh.
Documentation and report migration
examples/puzzletron/README.md, examples/puzzletron/docs/*.md, examples/puzzletron/reports/**
Documentation now describes structured results, catalogs, detached inspection, HTML refresh, and historical evidence boundaries. Legacy indexes and campaign READMEs are removed or replaced.
Task-local runtime caches
modelopt/torch/puzzletron/orchestration/task_launcher.py, examples/puzzletron/configs/site.example.yaml, examples/puzzletron/docs/slurm_configuration.md, tests/unit/torch/puzzletron/test_orchestration_task_topology.py
The task launcher creates isolated cache directories under temporary storage and preserves existing cache settings.

Estimated code review effort: 4 (Complex) | ~60 minutes

modelopt/torch/puzzletron/orchestration/reporting.py (1)

100-101: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

Use one shared result-path helper as an optional refactor.

The current helpers resolve the same results/result.json path, so completion detection does not currently fail. A future change to only one definition would make the exact path comparison return false. Share the helper across run_reporting.py, reporting.py, and reusable_allocation.py.

Inline comments:
In `@examples/puzzletron/README.md`:
- Around line 14-15: Fix the README table-of-contents links for “Start here:
lifecycle smoke,” “Choose the next task,” and “Documentation map” so their
fragments match existing headings, or add matching headings where appropriate;
ensure all three links navigate correctly and satisfy Markdown lint.

In `@modelopt/torch/puzzletron/orchestration/controller.py`:
- Around line 1321-1326: Make both publish_controller_result call sites nonfatal
by catching Exception and logging a warning. At the running-status publication
in modelopt/torch/puzzletron/orchestration/controller.py lines 1321-1326, keep
the controller loop running after failure; at the final publication in lines
1686-1692, fall back to a None result path while preserving result_finalized to
match the written result so run() still returns a mapping and orchestrate.main
reaches write_allocation_result.

In `@modelopt/torch/puzzletron/orchestration/reusable_allocation.py`:
- Around line 130-137: Update the recovered-result acceptance logic around
result_record and has_result to read results/result.json and require
validate_result to pass with the expected run identity and finalized state, in
addition to the existing canonical path and file checks. Only treat the
allocation as complete when the validated file corresponds to the current run;
otherwise continue recovery and start a new allocation.

In `@modelopt/torch/puzzletron/orchestration/run_reporting.py`:
- Around line 504-505: Update _metric_semantics so token_accuracy is not
projected as canonical quality.token_accuracy while its denominator and
aggregation remain producer_defined; emit a producer-scoped metric name when the
denominator is unknown, matching the existing lm_loss handling. Preserve
canonical quality.token_accuracy only when its required unmasked_target_tokens
denominator and target_token_weighted_mean aggregation are explicitly available.
