The scope door's first live test showed the episodes editor leading its
field menu with People (Author/Narrator/Contributor) and Publishing —
book-only fields that can never match an episode row — while the fields
the scope exists for (Feed, Downloaded, Played) sat below the fold.
Root cause: the registry's book fields carry no Scopes restriction
(nil = all scopes), a leftover from before the episode fields existed.
35 unambiguous book-only fields (people, publishing metadata, topics,
series/comics, identifiers, cover, reading-specific statuses) are now
tagged Scopes:books. Title, description, published dates, language,
file facts, explicit, the my-reading group (listening progress is
real), and collection stay dual-scope. Parse continues to accept the
hidden fields everywhere (their composed clauses simply match nothing
on episode rows) — this governs the AUTHORING surface, not the
grammar.
TestFilterParseValidation's empty-root rejection updated to the new
contract (empty root legal — the seed; nested empty groups still
invalid), and TestEpisodesScopeHidesBookOnlyFields pins both scopes'
vocabulary.
