X2 Help
X2 in one paragraph: the kernel enforces the invariants in the build, so the skills only exist to capture human decisions at the right moments. The flow runs through three gates, each a prompted human turn that blocks the next phase: stories approved; the prototype approved at Claude Design and then approved again after copy-down (the lock); then ratified green, the audited exit report read and accepted. Green is declared by the slice-exit report and audited, never by prose. The sole metric is human turns per shipped slice, kept in a ledger file in the repo.
