Development record

commands/ideate.md:200 says exit 2 means 'nothing was written', and 18-ideate.md:178-180 says 'a run never leaves a verdict nothing points at'; when the pointer write fails and the rollback also fails, internal/core/ideate/record.go:219-221 returns 'THE ROLLBACK FAILED — remove ... by hand', which internal/surface/cli/ideate.go:76-83 exits 2 with the verdict still on disk.
