Greptile Overview

Greptile Summary

This PR fixes subflow log rendering by threading a stable subflow identifier (iterationContainerId) through the execution pipeline (executor iteration context → SSE events → UI console store) and updating the terminal tree builder to group iterations by (iterationType, iterationContainerId, iterationCurrent).

It also tightens console update targeting by allowing updateConsole to match on executionOrder/iteration metadata, which helps avoid updating the wrong entry when the same blockId appears multiple times within an execution (e.g., repeated iterations).

Key areas touched:

• Executor iteration context/type updates (IterationContext now includes iterationContainerId, and iterationTotal becomes optional)
• SSE event payload typing + event emission includes iterationContainerId
• Terminal UI grouping logic now separates subflows by container id
• Console store update matching optionally includes executionOrder and iterationContainerId

Confidence Score: 3/5

• This PR is likely correct but has a couple of edge cases that can break console updates or subflow grouping.
• The core change (adding iterationContainerId and grouping by it) is consistent across executor → SSE → UI. However, tightening update matching on executionOrder can prevent updates after hydration/refresh, and iterationContainerId can still be undefined for parallel branches if parallelId is missing, collapsing groups to 'unknown'. Also, the new per-block info logging in the API route may be too noisy for production.
