Development record

The lab chapter says every path is written in tilde form (.abcd/development/brief/04-surfaces/31-lab.md:180). The matrix plan's 'to start it' line and its JSON approve_with embed the declaration argument unredacted (internal/surface/cli/lab_matrix.go:90), so a declaration under the home directory given by absolute path is printed with that absolute path. The refusal paths of the same verb do redact it.
