Fleet Migration Factory

Turn a large rewrite into a repeatable assembly line of independently verifiable cutovers. Optimize for verified throughput: many disjoint slices may advance in parallel, but no slice advances on narrative status or stale proof.

Resource guide

• Read references/fleet-migration-patterns.md before choosing slice boundaries, states, parity gates, concurrency, or cutover policy.
• Use scripts/validate_fleet_ledger.py when the migration adopts the portable ledger shape in the reference. From this repository's root, run python3 -m unittest -v skills/fleet-migration-factory/scripts/test_validate_fleet_ledger.py after changing the validator; the same suite belongs in the repository check and CI gates. Prefer an existing repo-native schema and validator when one already owns this fact.
• Load the target repositories' local architecture, delivery, and safety rules. This public skill does not replace them.
