This test calls skipBranchDependents with only a simple action chain, but the production change specifically adds synthesis and traversal for missing fan-out body and collect outputs. The existing coordinator fan-out test also pre-creates those outputs. Add a coordinator-level case where the scoped outputs are absent before the false branch is evaluated; otherwise the main fan-out repair can regress without being detected.

This changes the user-visible terminal roster state and progress projection, but the PR does not add or reset and verify a living QA scenario. The repository directive requires every changed user-visible behavior to update the affected docs/qa/scenarios/ entry and record a verified result before completion. This requirement must be satisfied before merging.

Continue traversal from existing skipped outputs.
When skipBranchDependents encounters a non-pending output, it exits before enqueueing that node’s dependents. A partial persisted output set can leave a descendant pending. Because dependenciesSucceededForOutput treats branchSkippedOutputRef as successful, that descendant can be scheduled instead of skipped. Enqueue descendants for existing skipped outputs with a visited-key guard.

What & why
In a multi-round Loop (such as
review-and-fix), when a later round evaluates a branch decision to false (for instance, no issues found in review), downstream branch-dependent nodes are intentionally skipped. However, when the Loop completed with statusdone, unexecuted downstream nodes (e.g.fix_batchwithin a fanout, or other skipped dependents) were projected in the roster as:pending("This step never ran")instead of a terminal non-run state.
In addition, in
skipBranchDependents, when a branch-skipped dependent node was not already present in the existing generation output indexes (such as dynamically scoped fanout bodies), it was not synthesized into the outputs map or traversed down its dependent queue.This fix ensures:
control_plan_branch.go,skipBranchDependentsproperly synthesizes skippedGenerationOutputentries withbranchSkippedOutputRefwhen missing from output indexes, and traverses into nested fanout body scopes.roster.go,applyRosterOutputprojects nodes withbranchSkippedOutputRefasNodeStateNotTaken.ProjectRoster, any unexecuted nodes remaining inNodeStatePendingwith 0 attempts in a terminal run (source.Run.Status.Terminal()) are projected asNodeStateNotTaken.How you verified it
