📋 Decision Context

Question:

How to make the Railway deploy CLI more stable and handle edge cases?

Task: Deploy CLI stability improvements

🎯 Decision Made

Chosen:

Add comprehensive stability features - context-based state, push verification, merge cleanup, unique stash IDs, exponential backoff, branch validation

Options Considered:

Keep simple with minimal error handling
Add comprehensive stability features
Use external deployment service
Rely on Railway's native git integration only

💭 Reasoning

The CLI encountered multiple stability issues: (1) Race conditions from MCP/Cursor writing files between pre-flight and checkout, (2) Global state variables causing stash conflicts, (3) Merge state left over from failures, (4) Push verification missing, (5) Local branch refs stale after push. The solution uses a deployment context object to encapsulate all state, adds push verification by comparing remote refs, cleans up merge/rebase state before operations, uses unique stash IDs per deployment timestamp, adds exponential backoff for retries, and validates all branches exist before starting.
