Development record

`04-surfaces/38-land.md:352` lists the steps in the JSON as `origin` when it reports a stale default, `gate`, `announce`, `push` and `enqueue`, or `land` alone. `internal/core/landing/withdraw.go:237,272,276,292` adds a further step named `withdraw`, with status `left` or `done`. Lines 98-103 of the chapter describe the act but the list does not name its step.
