Rail Review

Review git diff <fixed-point>...HEAD on two axes in parallel sub-agents:

• Standards — repo coding standards + Fowler smell baseline (repo docs win on conflict)
• Spec — faithfulness to the originating docs/monorail/**/spec.md and/or task file

Process

1. Pin the fixed point

Whatever the user said is the fixed point — commit SHA, branch, tag, main, HEAD~5, etc. If missing, ask.

Capture: git diff <fixed-point>...HEAD and git log <fixed-point>..HEAD --oneline.

Confirm git rev-parse <fixed-point> and a non-empty diff before continuing.

2. Identify the spec source
