Rail Align

Sharpen an idea before spec/build. One mode — grill it in this conversation until the decision tree is resolved, then persist align.md and continue the planning chain.

Confirm with the shell before concluding either file is missing (ls docs/monorail/work-tracker.md docs/monorail/domain.md, or read the paths directly) — search tools skip gitignored paths, so an empty Glob/Grep result is not evidence of absence. If a file is missing on disk, tell the user to run /rail-setup first and stop.
