Development record

`04-surfaces/27-implement.md:63` says every sub-verb refuses outside a checkout or in a repository with no commit, with two exceptions, the load check and the report given a log file. `abcd implement stop` is a third: its `RunE` (`internal/surface/cli/implement_stop.go:198-213`) reads the caller, takes the stop home and sets or lifts the stop, and resolves no checkout.
