📝 Walkthrough

Walkthrough

The installer now supports configurable Istio versions, direct platform repository fetching, chart-based CRD detection, stale CRD cleanup, dynamic infrastructure CRD versions, and readiness diagnostics. KPI conversion supports both identifier schemas. The plugin uses nested analysis settings and exposes KPI catalog metadata.

Changes

Platform installation updates

Layer / File(s) Summary
Resolve repositories and extension CRD specifications
projects/mcp_gateway/toolbox/platform_helpers.py, projects/mcp_gateway/toolbox/install_platform/main.py
Platform repositories use direct shallow fetches and resolved-ref markers. MCPGatewayExtension details come from chart CRDs. Stale CRDs are removed before extension creation.
Configure and patch the Istio version
projects/mcp_gateway/orchestration/config.d/infrastructure.yaml, projects/mcp_gateway/toolbox/platform_helpers.py, projects/mcp_gateway/toolbox/install_platform/main.py
The installer reads istio_version and patches matching Istio and IstioCNI manifests before applying them.
Capture service-mesh readiness diagnostics
projects/mcp_gateway/toolbox/install_platform/main.py
The readiness task reports conditions and saves full resource JSON under the artifacts directory.
Adapt infrastructure resources to stored CRD versions
projects/mcp_gateway/toolbox/apply_infrastructure/main.py
Infrastructure manifests use the detected storage-served MCPServerRegistration version.
Clean up MCP Gateway CRDs
projects/mcp_gateway/toolbox/cleanup_platform/main.py
Controller cleanup deletes the MCPGatewayExtension CRD.
Update the nightly pipeline target
projects/mcp_gateway/orchestration/config.yaml
The nightly pipeline uses the updated cluster and owner values.

KPI schema compatibility

Layer / File(s) Summary
Normalize KPI identifiers and report empty metrics
projects/caliper/engine/kpi/format.py, projects/caliper/engine/kpi/kpis_to_mlflow.py
KPI formatting emits id and accepts legacy kpi_id. MLflow conversion reports runs without scalar metrics.

Plugin analysis contract

Layer / File(s) Summary
Update plugin configuration and catalog access
projects/mcp_gateway/postprocess/mcp_gateway/plugin.py, projects/mcp_gateway/postprocess/tests/test_mcp_gateway_plugin.py
AnalysisConfig uses label fields and nested scalar regression settings. MCPGatewayPlugin exposes KPI catalog metadata. The test validates the updated schema.

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

Cover all updated configuration fields in the test.

The test checks comparison_labels and max_relative_regression only. It does not detect incorrect ignored_labels, sorting_labels, or min_baseline_points values. Add assertions for the remaining fields.

Restrict replacement to the Istio resource spec.version.

Line 317 replaces every indented version: key in a selected YAML file. The file checks do not bind that key to an Istio or IstioCNI resource. A different nested version: field can therefore be overwritten with the Istio release value.

Parse each YAML document and update only spec.version for kind: Istio and kind: IstioCNI.

kpis-to-mlflow only read nested "id", while catalog-based hierarchical
kpis.json used "kpi_id", so metrics.json was empty and MLflow runs had
no metrics.

Both bugs stem from the KPI analyze engine's current schema (nested
current_value/details.{baseline_mean,relative_change}) not matching
assumptions baked into older downstream consumers.

1. caliper_slack.py: _format_change_line()/_is_improvement() called
   float() directly on row['current_value'], which is now a
   {"value": x, "comparison_keys": {...}} dict, not a scalar. This
   raised 'float() argument must be a string or a real number, not
   dict', which set notification_failed=True and failed the whole
   export-artifacts CI task (see export.py's
   'if export_failed or notification_failed: return 1, "failed"').
   Also fixes a silent mismatch: 'relative_change_pct' doesn't exist on
   result rows (field is details.relative_change, a fraction, not a
   top-level percent), so the reported pct was always 0.0.

   Added _unwrap_scalar()/_relative_change_pct() helpers and applied
   them in both call sites. Updated test_caliper_slack.py fixtures to
   match the real nested schema instead of the legacy flat one.

2. commands.py (analyse-kpis CLI): the HTML regression report was only
   generated when status_data.success was True. But the analyze engine
   sets success=False precisely when a regression is detected
   (StatusLevel.REGRESSION_DETECTED) -- exactly the case where the
   visual report is most needed. Passing runs got kpi_analyze.html,
   regressed runs silently did not. Changed the gate to
   status_data.output_file (set whenever a report was actually
   written, success or not) instead of status_data.success. Added
   test_analyse_kpis_html.py, verified it fails on the old gate and
   passes with the fix.

CURSOR - ## Fix: Slack notification crash + missing HTML regression report on regression runs

Root-caused and fixed two bugs surfaced by the real mcp-gateway regression testing run (commit 37075f35, Prow job pull-ci-openshift-psap-forge-main-fournos/2107933032936640512), both stemming from downstream consumers not matching the KPI analyze engine's current result schema (current_value is a nested {"value": x, "comparison_keys": {...}} object; baseline_mean/relative_change live under details, not top-level).

1. caliper_slack.py — crash on regression Slack notifications

_format_change_line()/_is_improvement() called float() directly on row["current_value"], which is a dict, not a scalar:

WARNING: Failed to send per-project Slack notification: float() argument must be a string or a real number, not 'dict'
ERROR: Notification sending failed

This set notification_failed=True, which per export.py's if export_failed or notification_failed: return 1, "failed" failed the whole export-artifacts CI task — the actual cause of the FournosJobFailureError: ... Tasks Completed: 6 (Failed: 1) requiring /retest. Also fixed a silent mismatch: relative_change_pct doesn't exist on result rows (it's details.relative_change, a fraction), so the reported % was always 0.0.

Added _unwrap_scalar()/_relative_change_pct() helpers; updated test_caliper_slack.py fixtures to the real nested schema.

2. commands.py (caliper kpi analyse-kpis --html) — regression HTML report silently skipped

The HTML regression report (kpi_analyze.html) was only generated when status_data.success was True. But the analyze engine sets success=False precisely when a regression is detected (StatusLevel.REGRESSION_DETECTED) — exactly the case where the visual report is most needed. Passing runs got the HTML; regressed runs never did. Changed the gate to status_data.output_file (set whenever a report was actually written) instead of status_data.success.

Added test_analyse_kpis_html.py, verified it fails against the old gate and passes with the fix.

Both fixes verified against the actual downloaded regression artifacts (kpi_analyze.json from the v0.9.0→v1.0.1 comparison run) and with the full test suite (uv run pytest, matching CI's default testpaths, 100% pass).

Error: FournosJobFailureError: FOURNOS Job 'forge-mcp-gateway-20261008-085025' failed: Tasks Completed: 2 (Failed: 1, Cancelled 0), Skipped: 0

/test fournos mcp_gateway demo

/replot.url https://mlflow.apps.psap-automation.ibm.rhperfscale.org/#/experiments/201/runs/02e6234c09004aac809c1a38cce98484/artifacts?workspace=mcp-gw-cpt

The /replot.url PR directive sets the config override
caliper.replot.url, which config.py's apply_config_overrides() applies
via _create_first_parent_config_key(). That helper requires the
*parent* key (caliper.replot) to already exist as a dict in the
project's config before it can add a new child key under it.

mcp_gateway's config.yaml never declared a caliper.replot section
(only caliper.postprocess), even though CIApp.build() unconditionally
registers the shared 'replot' CLI command
(projects.core.library.replot.caliper_replot_entrypoint) for every
project, mcp_gateway included. So the first time anyone tried
/replot.url against mcp_gateway, config.init() crashed:

  ValueError: Config key 'caliper.replot.url' does not exist, and
  cannot create it at the moment :/

'replot' isn't in FORGE_LENIENT_STEPS, so this isn't swallowed -- it
fails the whole CI run immediately after checkout, before any
postprocessing runs.

Added the same caliper.replot: {url: null, keep: false} block that
projects/llm_d/orchestration/config.yaml and
projects/skeleton/orchestration/config.yaml already have. Verified by
reproducing the exact crash against the pre-fix config and confirming
it's resolved post-fix, using the actual mcp_gateway config
loading/override path (projects.core.library.config.init()).

Note: projects/inference_playbooks and projects/minimal have the same
latent gap (import caliper_replot_entrypoint but lack caliper.replot
in their config) -- left out of scope here since they weren't
affected by this run, but worth the same fix if they're ever used
with /replot.url.
