distributed

Engineer distributed systems for correctness under partial failure — the realities a single-machine programmer (and an agent) gets wrong by default. First skill: holdfast, the distributed-correctness lens. Its one shift is the third state — a remote call can succeed, fail, or leave you not knowing which — and its complete eight-stage map is: frame · communication · ordering · replication · consensus · sharding · fault-tolerance · coordination. Note: the gates are enforced by the `checklist` CLI, which installs separately — see the repository README.
