popertots f9e8385d5a fix: auth/2FA security — stdout-log code delivery is dev/test-only, production fails closed until email/SMS; verification-code hashing, lockout recovery, sabredav fail-closed
- TWO_FACTOR_ALLOW_LOG_DELIVERY production opt-in REMOVED: plaintext codes are written to the stdout log ([2FA]/[VERIFY]) only in dev/test builds as a local DEV ONLY feature while email/SMS delivery (P6) is implemented. Production builds have no delivery channel and code issuance fails closed (503) under any configuration — no silent log-based code leak
- verification/2FA codes hashed at rest (HMAC-SHA256 via TWO_FACTOR_PEPPER, CHAR(64)); [VERIFY] dev log relay; per-user brute-force budget; password_reset purpose clears lockout for self-service recovery; dummy-bcrypt on login no-user path kills timing oracle
- sabredav weak-password list + entropy gate; .env.example ships fail-closed DAV_ADMIN_PASSWORD
- delete-account re-auth (current_password + fresh 2FA code when enforced)
- prod-tag suite (run-prod-tag-tests.sh) compiles and runs the production 2FA issuance gate: production ALWAYS reports no delivery channel and refuses issuance after the pepper check
- startup_checks_test SNAPSHOT_ENC_KEY values built at runtime so gitleaks sees no secret-shaped literals
- env-docs parity updated (flag removed, 38 vars)

// M17 follow-up (ITEM 2): twofa_prod.go is excluded from the test,dev suite
// (`!dev && !test`), so its fail-closed branches were never exercised in CI —
// the old twofa_prod_test.go only runs its assertions in a genuine production
// build and skips under the test tag. The pure decision logic now lives
// build-agnostically in twofa.go (twoFAEnsureIssueAllowedStrict /
// twoFAPepperConfigured / twoFADeliveryChannelConfigured); these tests exercise
// those branches in the STANDARD test,dev run, so a regression in the prod
// fail-closed behaviour is CI-visible even though the prod file itself is only
// compiled in a genuine production build.
//
// DELIVERY POSTURE (current): stdout-log delivery of 2FA codes is a
// DEV/TEST-ONLY local feature. Production has no delivery channel of any kind
// (email/SMS unwired, P6; no production opt-in to log delivery), so the strict
// gate refuses issuance unconditionally after the pepper check.

// (a) pepper unset → issuance refused (errTwoFAPepperRequired — an unsalted
// digest in the 1M code space would be offline-brute-forceable);
// (b) pepper set but no delivery channel → issuance STILL refused
// (errTwoFADeliveryUnavailable — production has no channel until email/SMS
// lands, P6; the 503-style error the handlers surface as
// StatusServiceUnavailable). Issuance can never succeed in a production build
// until a real transport exists.
