The merge creates the brand capability (two requirements) and extends the
catalog browse requirement with the brand filter, the sales sort and a real
sold count. openspec validate --all --strict stays green at 14 specs.
With every box now checked, docs/TBD-migrate-wave.md is deleted, as its own
instructions require. Its two durable notes move to the README instead of
disappearing with it:
- `nuxt build` does not typecheck, so a green build is not the type gate the
verification section claimed. AGENTS.md told me to treat it as one, which is
why waves 1-5 over-reported "builds pass" as evidence.
- the list of what stays deliberately mock: addresses, coupons, favourites,
account stats, the seckill/collective/integral pages, reviews, and the
fixed-data adapter itself, which the adapter spec requires for rollback.
The README's verification block also gains the real test count (29, not 16).
