Development record

The brief at .abcd/development/brief/02-constraints/04-naming.md:222 says: `aliases`: array of prior names a repo has had, 'Recorded in per-root-sha `meta.json`' (unmarked, so a delivery claim per the truth rule). The shipped surface differs: The per-repo meta.json that ahoy install writes (internal/core/ahoy/apply.go) holds root_commit, name, github and corpus only; no code in internal/core/ahoy reads or writes an `aliases` field, and the index.json entry struct (internal/core/ahoy/store.go) has none either. (v0.14.2 release crosscheck, false-claim, raised by opus in a32.)
