Inline comments:
In `@docs/agentrax.md`:
- Around line 51-53: Update the state-machine documentation around the fail-safe
rollback behavior to describe Prometheus unavailability triggering rollback
after a fixed 60-second timeout, and remove the implication that
--fail-safe-timeout is configurable.
In `@go.mod`:
- Around line 75-76: Upgrade the indirect dependencies golang.org/x/oauth2 and
golang.org/x/net to versions meeting the required minimums of v0.27.0 and
v0.56.0 respectively, then regenerate the Go module graph so go.mod and go.sum
remain consistent.
In `@internal/controller/agentdeployment_controller.go`:
- Around line 191-195: Update the canary reconciliation paths reached by
CanaryController.Step to use controllerutil.CreateOrUpdate for Deployment,
Service, ServiceMonitor, and HPA resources, including HPA restoration, instead
of separate Get/Create or Update operations. Set each resource’s owner reference
inside its CreateOrUpdate mutate function and preserve the existing
desired-state reconciliation behavior.
- Around line 179-203: Reorder the Reconcile flow so canary handling via
isAbortRequested, PhaseRolloutInProgress, and isCanaryTriggered occurs before
updating the stable Deployment from spec.image. During rollout, use
status.stableVersion as the stable Deployment image, and ensure Rollback
restores that stable image rather than only deleting canary resources and
restoring the HPA; switch to spec.image only after promotion.
In `@internal/rollout/canary_test.go`:
- Around line 159-171: Update the self-healing test around the c.Step call to
capture and assert its error before checking recreated resources, so failures
report the actual Step error. After retrieving the restored HTTPRoute, also
validate its configured traffic split remains 80/20, using the existing route
structure and test assertions.
- Around line 480-494: Extend the insufficient-sample test around executePause
to verify that no rollback occurs: assert the AgentDeployment remains in its
expected rollout phase and confirm the canary resources still exist. Keep the
existing RequeueAfter and ConditionSampleInsufficient assertions, and use the
test’s established phase and resource identifiers.
Apply the same fix in `@internal/rollout/canary.go` around lines 283 - 289.
- Line 354: Update prometheusServer and its usages in the canary tests around
the affected test cases so fixture responses are selected by the Prometheus
query string rather than request order. Define query-keyed JSON fixtures for
both test scenarios and preserve each query’s expected values without relying on
Evaluate call sequencing.
In `@internal/rollout/canary.go`:
- Around line 250-308: In internal/rollout/canary.go lines 250-308, update the
maxWait calculation in the pause-extension flow to cap 3×duration at an absolute
15-minute ceiling, and simplify remaining accordingly while preserving the
existing requeue behavior. In docs/agentrax.md line 51, document both
pause-extension bounds: 3×pause_duration and the absolute 15-minute maximum.
Apply the same fix in `@docs/agentrax.md` at line 51.
- Around line 490-514: Update ensureHTTPRoute in
internal/rollout/canary.go:490-514 to set the controller reference on existing
HTTPRoutes and skip the update when the existing spec already matches
desired.Spec. Update the canary Deployment reconciliation in
internal/rollout/canary.go:396-424 to set its controller reference and reconcile
the complete pod template rather than only the container image.
- Around line 490-514: Update ensureHTTPRoute to adopt existing HTTPRoutes by
setting the controller reference when needed, while preserving existing
ownership handling. Compare existing.Spec with desired.Spec using Kubernetes
semantic equality and call Client.Update only when the specs differ or the owner
reference must be added; otherwise return without writing, while retaining the
current create and error behavior.
- Around line 334-345: Update Controller.promote to return an error immediately
when ad.Status.CanaryVersion is empty, before fetching or mutating the stable
Deployment; preserve the existing promotion flow for non-empty versions.
- Around line 518-581: Update the Service reconciliation alongside
desiredHTTPRoute to create and manage the canary Service named with
canaryDeploymentSuffix, using a selector that targets only canary pods. Adjust
the stable Service selector to exclude canary-labeled pods, and ensure the
canary Service is deleted during promotion or rollback cleanup while preserving
the existing stable Service behavior.
- Line 218: Update both state-transition returns in the canary reconciliation
flow to use RequeueAfter: time.Second instead of Requeue: true, preserving the
existing successful result and error values. Adjust the corresponding assertions
in the canary tests to verify the one-second RequeueAfter behavior.
In `@internal/rollout/promql_test.go`:
- Around line 42-54: Update prometheusServer and the related tests to serve
recorded Prometheus JSON fixture files instead of generating payloads with
buildVectorResponse or embedding inline response strings. Preserve the existing
response sequencing based on responses, and load the appropriate real Prometheus
response fixture for each requested value.
In `@internal/rollout/promql.go`:
- Around line 140-168: Apply the documented default values for MaxErrorRate and
MaxP99LatencyMs before threshold evaluation, while preserving explicitly
configured values and the existing fail-safe handling for invalid error-rate
settings. Update Evaluate’s threshold setup and TestEvaluate_DefaultThresholds
to verify omitted limits still enforce the default error-rate and p99-latency
boundaries.
- Around line 34-66: Update the canary rollout resource generation so the stable
Service selector includes the stable variant label and a canary Service is
created with the canary variant selector, matching the HTTPRoute backend
reference. Ensure the canary Deployment pod labels and Service selectors use the
same variant key/value, and update requestCountQuery, errorRateQuery, and
p99LatencyQuery to filter on the propagated agentrax.io/variant label rather
than relying on an unpropagated variant metric label.

Use CreateOrUpdate for canary child resources.
Step reaches the canary Deployment and HTTPRoute reconciliation paths. The supplied helper implementations use separate Get plus Create or Update calls. Convert these paths, including HPA restoration, to controllerutil.CreateOrUpdate and set the owner reference inside the mutate function. This prevents conflicts and preserves idempotency during self-healing.
As per path instructions, “Use controllerutil.CreateOrUpdate for all owned child resources (Deployment, Service, ServiceMonitor, HPA). Never use Create + Update in sequence.”

Use recorded Prometheus JSON fixtures.
prometheusServer uses generated response maps instead of real Prometheus response fixtures. Replace buildVectorResponse and the inline response strings with stored response JSON captured from Prometheus.
As per path instructions, internal/rollout/**_test.go must use “real Prometheus response JSON fixtures, not ad-hoc mock strings.”

Fix canary Service and metric label propagation.
The stable Service selector also matches canary pods because it omits agentrax.io/variant. No canary Service exists, although HTTPRoute references one. PromQL therefore cannot reliably isolate canary traffic.

Upgrade the OpenTelemetry SDK and Go version.
go.opentelemetry.io/otel/sdk v1.34.0 is affected by GO-2026-4394 and GO-2026-5426. Upgrade the aligned OpenTelemetry modules to v1.43.0 or later. This release requires Go 1.25.0, so update the Go directive and regenerate the module graph.

Use CreateOrUpdate for stable Deployment transitions.
Rollback and promotion use Get followed by Update on the owned stable Deployment. This bypasses idempotent reconciliation and can conflict with the main reconciler or external mutations.
internal/rollout/canary.go#L137-L148: restore the stable image throughcontrollerutil.CreateOrUpdateand set the owner reference in the mutate function.internal/rollout/canary.go#L374-L384: promote the stable image through the same idempotent reconciliation path.
As per path instructions, “Use controllerutil.CreateOrUpdate for all owned child resources (Deployment, Service, ServiceMonitor, HPA).”

Keep a stable HTTPRoute after promotion and rollback.
Deleting the HTTPRoute removes the Gateway API attachment that routes requests to the stable Service. The normal reconciler does not recreate this route outside an active canary. Promotion and rollback can therefore drop all Gateway traffic.
internal/rollout/canary.go#L162-L167: replace route deletion with a stable-only route reconciliation before canary cleanup.internal/rollout/canary.go#L396-L399: preserve or reconcile the stable-only route during promotion.docs/agentrax.md#L51-L51: document that rollback and promotion retain stable Gateway traffic.
As per path instructions, the canonical E2E scenario requires rollback “without reducing stable traffic.”
