Deal-breakers checklist

Early-warning list for monorepos and moon. Kill bad plans before they ship.

Lesson 6 Lesson 7 Playbook Architecture Glossary Mission

Reject or fix early

Smell Why it hurts Counter-move
Collocation only No graph/tasks/affected → slow mess moon workspace + projects + tasks
Full CI every push Cost scales with repo size, not change --affected / graph-aware CI
Unowned spaghetti deps Anyone imports anything; refactors die layers/tags + constraints / CODEOWNERS
No ownership map Review chaos; silent drive-by breaks owners + default CODEOWNERS paths
Wrong/missing inputs Cache lies; “green” misses real changes Declare inputs/outputs; fix hashes
No toolchain pins Laptop ≠ CI version roulette .moon/toolchains + full semver
Big-bang migration History/CI/habits blow up together Incremental adopt; migrate-nx/turbo if needed
Hard isolation needed Access, legal, release independence Stay polyrepo (or synthetic later)
