The lines under "Doc and comment drift" that the findings' own commits did not already fix: - security.md: a newer confirmation link replaces the older, a reset link is not replaced; html/template renders every page (no themes); the container keeps eight capabilities, named, not "KILL". - architecture.md: ImportKey writes over a name's key, as an import must; the error text reaches the browser on the Backup page's import refusal. - guide: with Caddy the key is in Caddy's data, so a full backup refuses until certs/ holds a copy (or back up caddy-data). - comments: sasldb2 holds application passwords in the clear (store, app/password.go); texthash folds ASCII (sender.go); the supervisor socket's group is supervisor (rpc.go); cert-reload's OpenSSL measurement was 3.0.x of bookworm; sendReset's limits (links.go). Migration 0013's comment stays as shipped. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
