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

buildStructuredEdits requires an active plan for the given planId and branch. GetActivePlan returns nil when no plan is registered (plan never created, already stopped/cleaned up, or wrong branch), so the function reports this error via fileState.onBuildFileError and aborts the build instead of dereferencing a nil plan.

Solutions

1. Verify the planId and branch passed to buildFile match an existing active plan (list active plans before building)
2. Ensure the plan isn't canceled/stopped before the build runs; check plan lifecycle ordering (create/activate before build)
3. If the plan context can be canceled mid-build, re-create or re-activate the plan and retry the file build
4. Fix stale client state that is resubmitting old plan IDs after a restart

Example fix

// before
fileState.buildFile(ctx, planId, branch, ...)
// after
if GetActivePlan(planId, branch) == nil {
    return fmt.Errorf("cannot build: no active plan %s on branch %s; create/activate the plan first", planId, branch)
}
fileState.buildFile(ctx, planId, branch, ...)

if p := GetActivePlan(planId, branch); p == nil {
    return fmt.Errorf("no active plan for %s/%s: create or reactivate the plan before building", planId, branch)
}
if p := GetActivePlan(planId, branch); p != nil && p.Ctx.Err() != nil {
    return fmt.Errorf("plan %s already canceled: %w", planId, p.Ctx.Err())
}

func hasActivePlan(planId string, branch string) bool {
    p := GetActivePlan(planId, branch)
    return p != nil && p.Ctx.Err() == nil
}

// buildFile-level handling before invoking buildStructuredEdits:
if !hasActivePlan(planId, branch) {
    return fmt.Errorf("cannot build file %s: no active plan %s on branch %s", filePath, planId, branch)
}
fileState.onBuildFileError = func(err error) {
    log.Printf("build aborted: %v", err) // surface to caller instead of swallowing
}

When it happens

Trigger: Calling buildStructuredEdits (via buildFile) with a planId/branch that has no active plan — the plan was never started, was stopped/canceled (its context canceled and it was removed), or a branch mismatch means GetActivePlan(planId, branch) finds nothing.

Common situations: Build request arriving after plan cancellation or session teardown (race between cancel and in-flight build), stale planId reused after restart, or a branch name that differs from the branch the plan was created under.
