- H now holds only small port interfaces (UserStore/LibraryStore/BookStore/
ProgressStore/BookmarkStore/RateLimiter/Scanner/Media/UploadSessions);
NewRouter is the composition root distributing *store.Store and *redispkg.R
- ports.Media gains EnsurePage; ChaptersOf returns ports.Chapter (media's
local duplicate dropped); *media.M now provably satisfies ports.Media;
ports.UploadSessions gains LibraryID for root validation before Complete
- content.go: duplicated page-index cache + cover self-heal + page extract
logic removed in favor of media service — same redis keys, same contract;
path traversal check stays in handler (403 semantics preserved)
- getLibrary/getLibRow merged into getLib(c, id); idParam helper dedupes
:id parsing; isUnique replaced by ports.IsUniqueViolation (Task 28 partial)
- main.go assembles media + upload and passes upload.U as scanner Sweeper
Full gate green: gofmt, vet, go test -p 1 (real PG+Redis, 0 skip)
