Reconcile Helm agent instructions with the post-v2 chart contracts

Description

The Wave 5 fallback reconciliation found two stale operational claims in charts/meraki-dashboard-exporter/CLAUDE.md. Lines 106-107 say NetworkPolicy emits OTLP egress only when config.otelEnabled is true, but MDE-0061 changed templates/networkpolicy.yaml so any enabled tracing, logs, or metrics channel emits the shared chart OTLP port; distinct ports remain an explicit extraEgress responsibility. Lines 74-76 still call the 256Mi/512Mi default SMALL-scale-only and direct agents to scale-tier comments whose recommendations MDE-0063 confirmed are unsupported by representative measurements. A future agent following either claim can regress logs-only or metrics-only egress, or restore unsourced resource recommendations. Reconcile the instruction text with the landed chart and MDE-0063 without inventing sizing figures.

Acceptance Criteria

• #1 The NetworkPolicy instruction states that any enabled tracing, logs, or metrics channel emits the shared chart OTLP port and explains the existing extraEgress route for distinct ports
• #2 The resource-sizing instruction no longer endorses unsupported scale-tier quantities and points to the representative-measurement contract tracked by MDE-0063 without adding a new estimate
• #3 All other claims in the touched Helm instruction paragraphs are checked against the current templates and values before the task is finalized

Definition of Done

• #1 just check (ruff format –check, ruff check, mypy, generated-doc drift, offline API conformance, and the marker-filtered pytest run with the 80% coverage floor — this is exactly what the CI test job runs)
• #2 just gen, when metrics, config, endpoints, collectors, the settings schema or the chart config changed — just check includes the drift gate and CI fails the build on it
• #3 Grafana queries in grafana/dashboards/*.json and grafana/alerts/ updated, if a metric or label name changed

Implementation Plan

Reconcile the touched Helm instruction paragraphs with current OTel NetworkPolicy behavior and the measurement-only resource contract, then verify every remaining claim in those paragraphs against templates and values.

Final Summary

Reconciled Helm agent instructions with the post-v2 chart contracts. Documentation and chart validation, just check, and just ci passed at 5e8d9c23b76a2f2edd531c15c776cbfbcc9134fa; exact-head CI 33843833956 and publication 33843966820 succeeded.
