Module email_ownership_verification 

Minting and mailing email-ownership verification codes.

Signup and every writer of user_details.email goes through here, so the code, the mail and the resend cap cannot drift between them.

Enums

VerificationEmailOutcome

Constants

FALLBACK_EMAIL_LANGUAGE

Language for the automatic sends, which have no UI language to work from.

MAX_CODE_ATTEMPTS

Wrong guesses one code tolerates before it is retired. Six digits are only safe with a cap.

MIN_RESEND_INTERVAL_MINUTES 🔒

Mail-bomb guard, not a quota: how soon after mailing a code we refuse another.

PURPOSE 🔒

Functions

queue_verification_email

Mails a fresh verification code to the address the account holds now.

queue_verification_email_best_effort

Queues the mail without letting a failure propagate: no signup or email change may be rolled back because the mail queue or the template is unavailable.
