Review Change Stack

📝 Walkthrough

Walkthrough

The change adds shared Caliper KPI dataclasses and migrates analysis, plugins, tests, and documentation to typed records, catalogs, summaries, and regression reports with dictionary serialization.

Changes

Caliper KPI datamodel

Layer / File(s) Summary
Core KPI datamodel and exports
projects/caliper/engine/kpi/dataclasses.py, projects/caliper/engine/kpi/__init__.py, projects/caliper/DATACLASSES_ARCHITECTURE.md
Adds shared dataclasses, serialization helpers, report queries, status values, aliases, package exports, and architecture documentation.

Structured analysis reports

Layer / File(s) Summary
Structured analysis reports
projects/caliper/engine/kpi/analyze.py, projects/caliper/tests/test_kpi_analyze.py, projects/caliper/STRUCTURED_SUMMARIES.md, projects/caliper/ANALYZE_MODULE_UPDATE.md
Builds typed findings, summaries, metadata, and RegressionReport objects. Serializes reports across normal, regression, no-test, and no-baseline paths. Updates tests for the new report shape.

Plugin KPI record and catalog migration

Layer / File(s) Summary
Plugin KPI record and catalog migration
projects/guidellm/..., projects/llm_d/..., projects/mcp_gateway/...
Migrates KPI records and catalogs from dictionaries to shared dataclasses. Serializes records and preserves scalar, 2D, source, and metadata fields.

Skeleton plugin adoption and validation

Layer / File(s) Summary
Skeleton plugin adoption and validation
projects/skeleton/postprocess/default/parsing/kpis.py, projects/skeleton/README_DATACLASSES.md, projects/skeleton/test_dataclasses_kpi.py
Migrates Skeleton records and catalogs to shared dataclasses. Adds typed regression report creation and standalone validation for construction, serialization, catalog generation, and regression detection.

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

Merge Risk: 🟠 High · up to 0420d

This PR replaces KPI dictionaries with shared dataclass-based records and reports across analysis and plugins, but the current implementation can fail to generate reports, lose multi-run regression data, or reject valid serialized reports during deserialization. Merge should be held until these correctness and compatibility issues are fixed.

302-305: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Make NO_BASELINE reachable.

findings can be nonempty only when current_kpis is nonempty, so Line 304 never runs. An empty baseline_kpis list also produces NO_TEST_PERFORMED instead of NO_BASELINE. Test baseline_kpis before the not findings branch.

🐛 Proposed fix for the status selection

             status = OverallStatus.REGRESSION_DETECTED

Retain every KPI record per kpi_id.

These dict comprehensions keep only the last record for each kpi_id. compute_kpis emits one record per unified result record and KPI, so the same kpi_id repeats across scenarios, workloads, and versions. The report then compares one arbitrary pair and misses regressions in the other pairs. Key the grouping by kpi_id plus the comparison labels, or keep lists and pair the records.

Preserve KPI display-format metadata.

build_catalog_from_functions still emits format for scalar KPIs and x_format/y_format for 2D KPIs. KpiCatalogEntry has no matching fields, so this mapping drops them. Consumers lose the KPI display format. Add the format fields to the shared catalog dataclass and copy them here.

Inline comments:
In `@projects/caliper/ANALYZE_MODULE_UPDATE.md`:
- Line 124: Update the documented metadata access in the RegressionReport
example to use the ReportMetadata attribute API: replace the metadata mapping
lookup with report.metadata.total_tested, preserving the existing total-tested
value.

In `@projects/caliper/DATACLASSES_ARCHITECTURE.md`:
- Line 114: Update all listed report examples to use the shared OverallStatus
vocabulary: document status as OverallStatus, use
OverallStatus.REGRESSION_DETECTED in the regression example, use the enum in the

projects/caliper/DATACLASSES_ARCHITECTURE.md lines 114 and 331, and

- Around line 651-652: Update the baseline aggregation in the analysis flow to
map 2D result dictionaries to scalar AUC values: when the result algorithm is
TWO_DIM_AUC_CHANGE, use details["current_auc"] and details["baseline_mean_auc"]
instead of summing the dictionary values. Preserve existing handling for other
algorithms, and add both 2D pass and regression coverage.
- Around line 675-677: Update the RegressionFinding construction in the
regression analysis flow to populate baseline_labels and current_labels from the
stored result labels and baseline comparison keys, and populate threshold_used
from details["config"]["max_relative_regression"]. Replace the current empty-map
and zero-value fallbacks so version extraction receives the actual metadata,
while preserving the existing RegressionFinding fields and behavior.

In `@projects/skeleton/README_DATACLASSES.md`:

genuinely pending plugin work and spell GuideLLM correctly wherever it remains.
- Around line 33-34: Update the documentation examples for
RegressionReport.status to use the matching OverallStatus enum values, including
PASS, REGRESSION_DETECTED, NO_BASELINE, and NO_TEST_PERFORMED, instead of

224-252 to consistently document the shared Caliper classes, include the valid
OverallStatus values, and describe the actual fields returned by
RegressionReport.to_dict().

Align the documented status API with OverallStatus.

RegressionReport.status uses OverallStatus values such as PASS, REGRESSION_DETECTED, NO_BASELINE, and NO_TEST_PERFORMED. The lower-case values shown here do not match the implementation. _build_report also returns (OverallStatus, RegressionReport), not only a report. Update all examples to use the enum values and the actual return contract. (raw.githubusercontent.com)

Fix report deserialization before documenting this path.

RegressionReport.from_dict(report_data) calls RegressionFinding.from_dict() for dictionary findings, but RegressionFinding does not define that method. A report with findings therefore raises AttributeError during deserialization. The method also leaves nested summary and metadata values as dictionaries. Rehydrate all nested dataclasses and add a serialized-report round-trip test. (raw.githubusercontent.com)

RegressionReport.from_dict and RegressionFinding deserialization so dictionary
findings no longer call an undefined method, and rehydrate nested summary and
metadata values into their dataclass types rather than leaving dictionaries. Add
a serialized-report round-trip test covering findings and nested fields.

The updated module maintains backward compatibility:
- Existing JSON report files have the same structure (just generated from dataclasses)
- Analysis configuration remains unchanged
- Function signatures preserved (only return types changed internally)
- Status codes and exit behaviors unchanged

Preserve the legacy report schema or document the breaking change.

run_analyse_kpis writes RegressionReport.to_dict(), which exposes top-level fields such as status, regression_count, and findings. It does not emit the documented analysis, overall, and results keys. Add and test a compatibility adapter, or update the migration documentation to describe the schema change.

With the analyze module updated, the next priorities are:

1. **Plugin Migration**: Update remaining plugins (GuideeLM, LLM-D) to use core dataclasses

Remove completed plugin work from “Next Steps.”

This PR already migrates GuideLLM, LLM-D, and MCP Gateway to the shared dataclasses. The line also misspells GuideLLM as GuideeLM. List only remaining work and use the correct plugin name. (github.com)

Preserve the KPI unit in each finding.

_run_regression_test() never adds unit to its result dictionary. Line 689 therefore assigns "" to every RegressionFinding.unit. Carry the current record unit into the result before building findings.

Re-raise catalog-generation errors.

This handler lets the script continue after get_catalog() fails. main() then reports that the dataclass implementation works. Re-raise the exception so the documented validation command returns a failure status.

Proposed fix
     except Exception as e:
         print(f"❌ Catalog generation failed: {e}")
+        raise

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
