-- migration adds nothing to it, for a reason that is easy to get backwards.
--
-- # Why assignments keep the text rather than pointing at a row here
--
-- The catalog is a rebuildable index (ARCH §6.12). What an image is keyworded
-- with is authoritative in the sidecar and in XMP `dc:subject` (FR-CAT-13),
-- and both of those carry a *string*. Rewriting the join to reference
-- `keyword_terms(id)` would mean a catalog rebuilt from sidecars had to invent
-- term rows before it could record a single assignment, and an integer that
-- means nothing on the other device would sit where the durable fact belongs.
-- It would also break `crate::query`, which matches `kw.keyword` directly and
-- must keep hitting `keywords_term` on a 50k library (FR-CAT-6).
--
-- So the text is the fact and this table is the *identity*: it exists to give
-- a rename and a deletion something a merge can key on, and to let a keyword
-- exist in the vocabulary before any photograph carries it.

revision INTEGER NOT NULL DEFAULT 1,

-- not resurrect it.
