In `@api/v1alpha1/agenticrun_types.go`:
- Around line 273-276: Update the comment for timeoutMinutes to describe only
the agent call timeout; remove the claim that it controls sandbox startup and
state that pod readiness uses the fixed five-minute defaultSandboxTimeout.
In `@controller/agenticrun/handlers.go`:
- Line 697: Preserve the original TimeoutMinutes when rebuilding step for an
escalation override near the escalation handling flow, so stepTimeout(step) in
the Agent.Escalate call receives the configured analysis timeout instead of
defaulting to five minutes. Update only the step reconstruction logic and keep
the existing escalation behavior unchanged.
In `@controller/agenticrun/sandbox_agent_test.go`:
- Line 764: Handle the error returned by fc.Create in the test setup, failing
the test through the existing test assertion mechanism if creation fails; if the
created object is unused, remove this setup instead. Do not ignore the return
value except for scheme-registration calls.

Inline comments:
In `@cmd/main.go`:
- Line 218: Update sandboxCRDInstalled to perform the
CustomResourceDefinitions().Get lookup with a bounded context, independent of
the zero rest.Config.Timeout from config.GetConfig. Distinguish a confirmed
missing CRD from timeout, permission, and transport errors; only the not-found
result should enable ForceBareMode, while other lookup failures must be surfaced
or handled as errors.
In `@controller/agenticrun/sandbox_agent.go`:
- Around line 18-20: Update the defaultAnalysisTimeout, defaultExecutionTimeout,
and defaultVerificationTimeout constants to 5 * time.Minute, and revise related
tests to assert the externally required five-minute timeout values rather than
merely comparing against those constants.
In `@controller/agenticrun/timeout_handler.go`:
- Around line 141-145: Update the timeout calculation around
effectiveStepTimeout to use the approval-selected resolvedStep, matching the
timeout path used for pod construction, instead of re-resolving the Agent from
run.Spec. Propagate any Agent read error from c.Get rather than treating it as a
nil Agent and applying the fallback timeout, so the caller can retry the timeout
check.
- Line 117: Update the timeout handling flow around the pod list and
handleTimeEvent so SandboxClaim resources are also tracked while awaiting pod
creation. Use each claim’s creation timestamp and step metadata to enforce the
startup timeout and transition stalled claims instead of leaving them Unknown;
preserve the existing pod-based timeout behavior.

Included review availability: Your plan provides up to 1 included review per hour; 0 remain after this review.
Adds spec.<step>.timeoutMinutes (1-60 min) to AgenticRunStep, threaded through resolvedStep -> effectiveStepTimeout() -> SandboxLifecycle.Create. Timeout precedence (highest to lowest): 1. Per-run override: AgenticRunStep.timeoutMinutes 2. Agent-level default: Agent.spec.timeouts.<step>Seconds 3. Built-in default: 10m analysis/execution, 30m verification Also injects LIGHTSPEED_AGENT_TIMEOUT_SECONDS and LIGHTSPEED_AGENT_MAX_TURNS env vars on the sandbox pod so the agent process itself knows its budget. Aligned with OLS-3743 layered timeout enforcement specification.

Summary:
This PR introduces a configurable timeoutMinutes setting for sandbox agent steps (Analysis, Execution, and Verification).
Reason for change:
This flexibility is needed to accommodate and properly support long-running tasks.
