No SQL text in the cache logic any more. Statements live in two files, parsed by sqlStatements (`-- name:` sections, as in finquick's brcal/gcbook.js) and imported as text (wrangler Text rule for *.sql): - cache-read.sql: selects only, checked when the module loads - cache-write.sql: schema, the v2 renumbering, etch, drops store.ts turns them into two frozen facets with domain methods: makeReader(sql) runs only the read statements (page, knownTotal, deepestPageSince, pagesThrough); makeWriter(storage) only the write ones (migrate, etch, dropPagesThrough), each change one transaction. The cache migrates in its constructor under blockConcurrencyWhile, as Cloudflare recommends, so readers never meet missing tables; the migration test plants v1 storage and evicts to get a fresh activation. A viewer() facet (PageViewer: stored pages and fill progress, from the reader alone) is added for the public page. Pure refactor: stored state and behavior unchanged. Generated-by: Claude Opus 5.5
