Comments only, no behaviour changed. modernc.org/sqlite v1.60.1 (the _pragma list on every connection, busy_timeout first; extended result codes; a deferred BEGIN; multi-statement Exec) and SQLite 3.53.4's documentation (transactions, WAL, foreign keys, NOCASE, upsert, julianday, partial indexes); htmx 2.0.4 src/htmx.js; the Fetch and HTML standards for Sec-Fetch-Site, Origin, SameSite, __Host-, CSP and defer order; Go's html/template. Comments the source contradicts are corrected - the driver does not serialise writes (SetMaxOpenConns(1) does), htmx:load fires per swapped element, no-store does not keep a page out of history. Left for their own commits: D-S3 a migration two processes can both run, D-S20 recipient case, D-B3 Origin: null under Referrer-Policy: no-referrer, D-H5/H6/H7/H9 (audit M11, stage 4).
