…hash rolling update pattern Adds a new applications/flagd/ example demonstrating the configmap hash rolling update pattern with OpenFeature's flagd feature flag daemon. flagd reads flag definitions from a ConfigMap-mounted JSON file, making pod restarts necessary when configurations change — an ideal use case for the checksum annotation pattern. - Helm chart with realistic flag definitions: fractional rollout (new-checkout-flow at 10%), boolean toggle (dark-mode), kill-switch (maintenance-mode) - Makefile-driven demo with `make problem` and `make solution` flows showing before/after behavior on minikube - Demo queries flagd's OFREP HTTP API to display actual flag evaluations, sampling 100 users for fractional rollouts to show distribution - Updated configmap-hash-rolling-update pattern README to include flagd as a second source application alongside MLflow Fixes #2 (kriscoleman/platform-examples) Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>
Lint, template, and integration test the flagd chart on CMX k3s. Verifies checksum annotation triggers rolling updates on config changes. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Prevents cascade failure when REPLICATED_PLATFORM_EXAMPLES_TOKEN is unavailable (e.g. fork PRs). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Gates the helm-install-test job so it skips rather than fails on fork PRs where REPLICATED_PLATFORM_EXAMPLES_TOKEN is not accessible. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
