The amber "auto-picked" warning persisted even after the user explicitly
picked a branch via the picker — the resort flow only updated the message
text from "auto-picked X" to "selected X" but kept the warning visible.
That reads as "you should review this" when in fact the user already did.
Now: when /api/resort honors a user's explicit branch selection, the
matching auto-picked-branch warning is dropped from WARNINGS. The
BranchPicker in the ModTable expansion (sortof-app.jsx ~818) keeps the
picker accessible if the user wants to switch branches later.
Initial /api/sort still emits the warning (the user hasn't picked yet);
suppression only kicks in once selected_modids honors a group's pick.
When user is on B42 and a mod requires the B41 mod_id (e.g.
truemusic_mixtape_megapack require=truemusic), the canonical wsid
(2613146550, B41-only) is rightly filtered out by the build guard —
but we were silently dropping the suggestion. Now we fall back to
MOD_ID_ALIASES: truemusic → TrueMoozic, suggest wsid 3632610172.
- _lookup_wsids_for_missing returns Dict[str, Tuple[wsid, suggested_mod_id]]
- build_warnings unpacks tuple, label clarifies rename when alias used
- adapters.build_response signature updated for new shape
