kyleandClaude Opus 5.5 0339dc13b2 Plan M4a: gatewayd in 15 tasks, with skeletons and given tests
Each task's tests were run against a reference at its end state; the end states were replayed
from master in order with the gate at each step (650 to 762 tests); each skeleton compiles
against its tests and fails them. The reference is kept off this machine. Lessons T27 (every
wait in a test has a limit) and T28 (mutate the reference before hand-over) come from this work.
