active plan not found for plan ID %s and branch %s

Error message

active plan not found for plan ID %s and branch %s

What it means

buildWholeFileFallback's first error return when GetActivePlan(planId, branch) is nil — the whole-file builder cannot proceed without the active plan context. The error is also passed to fileState.onBuildFileError.

Solutions

1. Activate/register the plan before calling the whole-file builder
2. Log and verify planId and branch values at the call site
3. Fix race conditions where plan cleanup runs before build fallback

if GetActivePlan(planId, branch) == nil {
    return fmt.Errorf("cannot run whole-file build: plan %s inactive on %s", planId, branch)
}

func hasActivePlan(planId, branch string) bool { return GetActivePlan(planId, branch) != nil }

out, err := buildWholeFileFallback(...)
if err != nil && strings.Contains(err.Error(), "active plan not found") {
    // recreate/activate plan and retry, or surface a user-facing plan-state error
}

When it happens

Trigger: Whole-file build invoked with a planId/branch pair that has no registered active plan.

Common situations: Branch mismatch (e.g. empty or renamed branch), plan finished/cleared before the fallback runs, or caller passing a stale planId.
