Development record

.abcd/development/brief/04-surfaces/05-intent.md:297-298 says every change appends a date, from-kind, to-kind and reason to `reclassification_history`, and line 89 gives the shape as `{ date, from, to, reason }`. `--reason` is required only with `--kind superseded` (internal/core/intent/reclassify.go:194-198), so `abcd intent reclassify <itd-N> --kind bundle-member --bundle <name>` exits 0 and writes an entry with no `reason` key.
