📝 Walkthrough

Walkthrough

Caliper adds typed command and postprocess status models, updates KPI analysis and orchestration to use them, persists typed YAML status data, and adapts notifications and tests. Documentation describes the new APIs. Additional changes update KPI metadata, environment detection, MLflow URLs, and generated HTML output.

Changes

Caliper status model migration

Layer / File(s) Summary
Public status contracts
projects/caliper/public/*, projects/caliper/README_POSTPROCESS_STATUS.md
Adds typed status and step-result dataclasses, enums, factories, YAML serialization, public exports, and documentation.
Typed KPI analysis results
projects/caliper/engine/kpi/analyze.py, projects/caliper/cli/commands.py, projects/caliper/tests/test_kpi_analyze.py, projects/caliper/tests/test_postprocess_integration.py
KPI analysis returns KpiAnalysisStatus objects with typed success, warning, regression, and failure paths. Callers and tests use attributes and capture reports.
Typed postprocess execution
projects/caliper/orchestration/caliper_invocation.py, projects/caliper/orchestration/postprocess.py, projects/caliper/orchestration/replot.py
Postprocess runners use typed step results and StepStatus values. KPI regression policy handling moves into run_analyse_kpis, and YAML output uses typed serialization.
Notifications and status validation
projects/caliper/orchestration/notification.py, projects/caliper/orchestration/cli_builder.py, projects/caliper/orchestration/postprocess_logging.py, projects/caliper/tests/test_notification_integration.py
Notifications parse and format PostprocessStatus data. Status-file parsing errors are logged and re-raised. Integration tests cover notification output and file-link behavior.

Integration and output updates

Layer / File(s) Summary
Integration boundaries
projects/core/library/env.py, projects/core/library/export.py, projects/caliper/orchestration/export.py, projects/core/library/reports_index.py
Adds Fournos environment detection, updates postprocess status parsing and exception propagation, moves MLflow workspace query parameters before the URL fragment, and adds a trailing newline to generated HTML.
Skeleton KPI metadata integration
projects/caliper/engine/model.py, projects/skeleton/postprocess/default/parsing/kpis.py, projects/skeleton/postprocess/default/plugin.py, projects/caliper/tests/stub_plugin.py
Adds the kpi_catalog plugin hook, extracts version labels from metadata or paths, configures version-based regression analysis, and updates stub KPI labels.

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

Merge Risk: 🟠 High · up to 7eab1

This PR changes status handling and KPI record labeling, but the current behavior can drop AI export data, report failed KPI processing as successful, interrupt notification delivery, and produce incorrect regression labels or exit codes. These high-impact correctness and reporting risks should be fixed before merge.

672-682: 🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win

Migrate KPI analysis consumers to the tuple contract.

analyze_kpis returns (KpiAnalysisStatus, report), but projects/caliper/cli/kpi_analysis.py calls result.get(...) on that tuple. The CLI therefore exits with failure before processing the result. Unpack the tuple and read status fields from status_data. Also make the report annotation optional, and make run_analyze return the same tuple shape for empty baselines.

1254-1285: 🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift

Make strict KPI regressions fail the postprocess result.

When fail_on_regression=True, run_analyse_kpis returns REGRESSION_DETECTED. _check_step_result_and_set_failure does not treat that status as a failure. _compute_final_status also receives has_regression=False. A detected regression can therefore produce a successful final postprocess status.

Persist the regression state and pass it to compute_final_postprocess_status. Apply the strict-policy decision before final-status computation.

256-286: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Update the AI-data caller for dataclass results.

_run_artifacts_to_ai_data now returns AiDataStepResult on every path. _run_artifacts_to_ai_data_step still calls result.pop("log_file", None). AiDataStepResult has no pop method, so every enabled AI-data export is converted into an exception and a failed step.

Proposed fix
-            log_file = result.pop("log_file", None)
+            log_file = result.log_file

Inline comments:
In `@projects/caliper/cli/commands.py`:
- Around line 1005-1009: Update the failure message in the status_data handling
to use status_data.error only when it is truthy, otherwise fall back to the
formatted status value. Preserve the existing success output and error-stream
behavior.

In `@projects/caliper/orchestration/caliper_invocation.py`:
- Around line 437-442: Update the status construction in the caliper invocation
flow to explicitly copy and normalize the log_file returned by
_execute_caliper_command into filtered_data before creating KpiAnalysisStatus.
Preserve the existing field filtering and ensure the resulting typed status
retains the analysis log path for downstream storage and linking.

In `@projects/caliper/orchestration/export.py`:
- Line 462: Update _mlflow_ui_links so workspace is URL-encoded and added to the
query string before the MLflow hash fragment for both run and experiment links,
using the format {base}?workspace=...#/.... Add coverage for a non-empty
workspace value.

In `@projects/caliper/orchestration/notification.py`:
- Around line 89-117: Update the artifacts_to_ai_data branch to read and use the
serialized ai_data_dir key instead of ai_eval_dir throughout, including
directory-link generation and output-file relative-path calculation. Preserve
the existing fallback behavior and output-file formatting.

In `@projects/caliper/orchestration/postprocess.py`:
- Around line 658-668: Update _check_step_result_and_set_failure to stop calling
result.get(...) for failed or warning statuses, since BaseStepResult is a
dataclass. Read result.reason and optional fields such as error and message via
direct access or getattr with appropriate defaults, preserving the existing
failure-recording behavior without raising AttributeError.

In `@projects/caliper/public/POSTPROCESS_MODELS_README.md`:
- Around line 19-31: Update the README’s public API example and all related
model examples to use the exported names PostprocessTestPhase and
PostprocessTestPhaseInfo instead of TestPhase and TestPhaseInfo, while leaving
the other imports and usage unchanged.

🌐 Web query:

MLflow web UI workspace URL parameter hash fragment query workspace

💡 Result:

In MLflow's web UI, the workspace is managed via the URL search parameter workspace (e.g., ?workspace=my-workspace-name) [1][2][3]. Key details regarding the MLflow UI's handling of the workspace parameter: 1. URL Search Parameter: The UI uses the workspace query parameter to maintain context across navigation [3][4]. It is not typically implemented as a hash fragment (which is used for client-side routing, often appearing as #/...) [4]. 2. Context Preservation: Recent updates ensure that the workspace parameter is preserved when navigating between tabs (such as Overview, Traces, or Model Registry) [3][5]. The UI uses internal utility functions (e.g., prefixRouteWithWorkspace and appendWorkspaceSearchParams) to ensure that workspace context is carried over into links and navigation events [4]. 3. Manual Navigation and Validation: While the UI may initially populate from a list of authorized workspaces, users can manually set or type a workspace name in the URL [1][2]. Recent improvements have made the UI more resilient, allowing users to navigate to syntactically valid workspace names even if they are not explicitly returned by the listWorkspaces API [1][2]. This prevents the UI from incorrectly stripping the ?workspace= parameter for users who have resource-level access but lack broad workspace-level permissions [2]. 4. Fallback Behavior: If the workspace parameter is absent, the UI often falls back to a workspace stored in localStorage or defaults to a default workspace [4][6][7]. If you are programmatically constructing URLs for the MLflow UI, you should append the workspace parameter to your query string, ensuring your routing logic respects the existing workspace context [3][4].

Citations:


Put workspace before the MLflow hash fragment.

MLflow reads workspace from the URL query string. _mlflow_ui_links currently appends it after #, so the UI may not receive the workspace context. Build both run and experiment links as {base}?workspace=...#/..., URL-encode the value, and test a non-empty workspace.

When KPI analysis returns regression_detected and fail_on_regression is enabled, _check_step_result_and_set_failure() does not set analyze_failed because it only handles failed and warning. _compute_final_status() also passes has_regression=False. The postprocess can therefore report success despite a configured failing regression.

Mark regression_detected as an analysis failure in this branch, or handle it in _check_step_result_and_set_failure().

Proposed fix
         if not self.config.analyze.fail_on_regression:
             logger.info("analyse_kpis warning ignored: fail_on_regression is not set")
         else:
-            self._check_step_result_and_set_failure("analyse_kpis", result)
+            if result.status.value == "regression_detected":
+                self.analyze_failed = True
+            else:
+                self._check_step_result_and_set_failure("analyse_kpis", result)

Read log_file from the typed result.

_run_artifacts_to_ai_data now returns AiDataStepResult. Line 1133 calls pop() on that object and raises AttributeError. The exception handler then records a failed AI-data step even when the export succeeded.

Preserve the subprocess exit code when the CLI omits it.

The pre-validation paths in projects/caliper/cli/commands.py write failure YAML without exit_code. KpiAnalysisStatus(**filtered_data) then defaults exit_code to 0, although result.returncode is nonzero. The persisted typed status reports a successful exit code for a failed command.

Set filtered_data.setdefault("exit_code", result.returncode) before constructing KpiAnalysisStatus.

Proposed fix
             filtered_data = {
                 k: v for k, v in status_data.items() if k in KpiAnalysisStatus.__dataclass_fields__
             }

Narrow this re-raise to status-processing failures.

send_notification() calls _build_enhanced_notification() at Line 127 before its file, GitHub, and Slack error handlers. The broad handler at Lines 742-745 covers artifact-link extraction, step-log discovery, and postprocess-status processing. Any recoverable link error can therefore abort all notification delivery. The fallback added at Line 744 is also never returned.

Keep the fallback for link-building failures. Propagate only the status-file failures that this change intends to expose. Update the send_notification() contract if propagated exceptions are intentional.

Support callable mapping values in create_label_extractor(). TestLabelExtractor.extract() treats each mapping value as a dotted path. The callable assigned to "version" raises at _extract_value_by_path(), so extract() returns {} and the configured version label is not added to KPI records. Pass one callable that returns the complete label dictionary or extend the mapping contract.

Match dates adjacent to underscores.

\b treats _ as a word character. Therefore, suite_2026-08-28_results does not match at either edge of the date. The record then receives the fallback version.

Use non-digit lookarounds, such as (?<!\d)(\d{4}-\d{2}-\d{2})(?!\d), and add a test for underscore-delimited path components.

Do not use the analysis date as the record version.

When no label or path date exists, this fallback assigns the current UTC date to every record. With comparison_labels=["version"] in projects/skeleton/postprocess/default/plugin.py, undated records receive the same version and are not treated as different-version baselines. Re-running the same data on another day also changes its version.

Preserve missing version information, or require a stable producer-supplied version before running version-based regression analysis.
