sd label add <id> <label> · sd label remove · sd label list <id> · sd label list-all — free-form tagging, with normalization (lowercased, trimmed, deduped) on the way in.

Labels are the framework’s only classification axis beyond type and priority, and they carry more weight than they first appear to. They are a filter on seeds-list, seeds-ready and seeds-search (including --label-any and --unlabeled); a plan step may declare labels: [...] that flow to the spawned child seed — merged additively into an adopted seed’s existing labels, never clobbering them; and they are one of the inputs seeds-plan-prompt uses to infer which mulch domain to mine prior art from.

Maps to no canonical SDLC stage — metadata maintenance.
