The browser pixel under-counts signups badly: ~96% of paid traffic is mobile
in-app browsers where iOS ITP / ad-blockers drop client events, and the OAuth
path never fired it reliably. Meta recorded ~0 registrations for a 7.5K-spend
campaign while PostHog saw 98 facebook signups — so Meta could neither optimize
toward nor attribute signups, which is the main driver of the low signup rate.
This adds a server-side CAPI CompleteRegistration:
- MetaCapiService + @Global module. Fail-open: no-ops unless META_CAPI_PIXEL_ID
+ META_CAPI_ACCESS_TOKEN are set; never throws (signup must not break).
SHA-256 hashed email + fbp/fbc/IP/UA.
- Fired from the better-auth user.create.after hook for ALL signups (reliable,
covers Google OAuth which the browser pixel missed entirely).
- A session-gated POST /analytics/meta/complete-registration endpoint adds
fbp/fbc/IP/UA (ad-click attribution) for the email path.
- The browser pixel now passes a shared event_id (signup_<userId>); the
premature Google client-pixel fire (fired on click, before completion) is
removed.
- All sources dedupe via event_id=signup_<userId>.
Activate by setting META_CAPI_PIXEL_ID + META_CAPI_ACCESS_TOKEN (Events Manager)
in the api env; META_CAPI_TEST_EVENT_CODE routes to Test Events for verification.

Lands the §9.3 "compliance + brand" tier of mailAudit.md as one PR. Six
changes share enough surface (notifications, shared utils, infrastructure)
that splitting them would require multiple stacked PRs.
#9 — Turkish-locale title-case for names at signup
• New `normalizeName()` in @sase/shared, locale-aware (İ/ı pairs handled
via toLocaleLowerCase('tr-TR') + matching toLocaleUpperCase). Hyphen-
aware, collapses whitespace, idempotent.
• Wired into better-auth's `user.create.before` hook so every new signup
gets canonicalised before the row lands in Postgres.
• 28 unit tests in packages/shared/src/index.spec.ts.
• Backfill script at `scripts/backfill-user-names.ts` (already run
against prod + dev — 210/402 prod users and 72/153 dev users
canonicalised, plus 71 Novu subscribers).
#10 — Email typo correction at signup
• New `suggestEmailFix()` in @sase/shared: exact-match typo dictionary
for the addresses we've actually suppressed (icould.com, gmial.com,
xn--gmail-bgd.com, …) plus Levenshtein ≤ 2 fallback against popular
providers.
• Inline UI hint on the register form — "Bunu mu demek istedin? <link>"
that swaps the email on click; PostHog event tracks acceptance.
#11 — Strip EN branches (decision: TR-only)
• 0/205 prod subscribers have locale='en' and there's no marketing in
English — the {{#equals subscriber.locale "en"}}…{{else}}…{{/equals}}
framework was dead code in all 10 templates.
• Templates updated in-place (avg ~30 % smaller). Renamed
`novu-welcome-tr.html` → `novu-welcome.html` for consistency with the
other 9 files.
• Novu workflow definitions in both Dev + Prod envs updated via Mongo:
subjects collapsed to TR-only, content replaced with new HTML
(mongodump/restore-safe).
• App code: `NovuRecipient.locale` and `NovuUser.locale` removed; the
`...(user.locale === "en" ? { locale: "en" } : {})` spread in NovuService
is gone.
#12 — DKIM rotated to 2048-bit RSA
• Postal default was 1024-bit (selector `postal-YeIm3w`). Generated new
2048-bit key, added DNS TXT `postal-2k260604._domainkey.sase.tr`,
atomically swapped `domains.dkim_identifier_string` +
`dkim_private_key` in Postal MariaDB, restarted Postal SMTP.
• Verified: outgoing welcome mail now signs with `s=postal-2k260604`
and a 256-byte signature body (vs the previous 128-byte 1024-bit
signature). Pubkey on DNS matches the private key.
• OLD TXT record (`postal-YeIm3w._domainkey`) stays in DNS for ~7 days
as a grace window for in-flight mail.
#13 — MTA-STS + TLS-RPT
• Extended the existing mailtrack Cloudflare Worker to also serve
`mta-sts.sase.tr/.well-known/mta-sts.txt` (`mode: enforce, mx:
mx.postal.sase.tr, max_age: 604800`). Workers Domain bound to the
mailtrack service via Cloudflare API.
• DNS:
`_mta-sts.sase.tr` TXT "v=STSv1; id=20260604111347"
`_smtp._tls.sase.tr` TXT "v=TLSRPTv1; rua=mailto:dmarc@sase.tr"
• Verified policy fetch returns 200 with the expected body; cert valid
(sase.tr SAN issued by GTS).
#14 — Unsubscribe preferences + RFC 8058 one-click endpoint
• New `email_preferences` table (migration 0011) keyed
(user_id, workflow), captures source for audit
(one_click / manual_link / settings_page).
• New `UnsubscribeController` at `/api/email/unsubscribe`:
- POST: Gmail/Yahoo one-click bot path (200 fast)
- GET: human-visit, renders a Turkish confirmation page
Both validate an HMAC-SHA256(`userId|workflow`) token under
`UNSUBSCRIBE_SECRET` — stateless, no DB lookup to validate, secret
rotation invalidates all outstanding tokens.
• `triggerNovu()` now mints the per-call `overrides.email.headers`:
`List-Unsubscribe: <https://…?u=&w=&t=>, <mailto:unsubscribe@…>`
`List-Unsubscribe-Post: List-Unsubscribe=One-Click`
Auth + payment workflows opt out via NO_UNSUBSCRIBE_WORKFLOWS so the
unsubscribe URL never appears on transactional mail.
• `NovuService.trigger()` pre-flight-checks `isOptedOut()` and skips the
trigger entirely if the user opted out. Fail-open on DB error so a
transient blip can't swallow auth mail.
• `lifecycle-email.processor.ts` (standalone BullMQ worker — no NestJS
DI) does the same check inline via a LEFT JOIN on
`email_preferences WHERE opted_out IS NULL`.
• Coolify env wired in both Prod and Dev apps:
`UNSUBSCRIBE_SECRET` (32-byte hex, distinct per env)
`UNSUBSCRIBE_URL_BASE` = `https://(dev.)sase.tr/api/email/unsubscribe`
## Companion sibling changes (already applied, NOT in this PR)
- Cloudflare worker `mailtrack` redeployed with mta-sts.sase.tr custom domain.
- Postal MariaDB `domains.dkim_identifier_string` + `dkim_private_key`
updated to the new 2k260604 selector (live since 2026-06-04 11:18).
- `postal-2k260604._domainkey.sase.tr` TXT record live at Cloudflare.
- `_mta-sts.sase.tr` + `_smtp._tls.sase.tr` TXT records live at Cloudflare.
- Novu Mongo notification + message templates updated to TR-only.
- 282 user names canonicalised across prod + dev + Novu subscribers.
## Verification snapshot
- Postal raw_headers (ID 157, post-rotation): `s=postal-2k260604` + 256-byte b=
- `dig +short TXT _mta-sts.sase.tr @1.1.1.1` ⇒ live id=20260604111347
- `curl https://mta-sts.sase.tr/.well-known/mta-sts.txt` ⇒ 200 with policy
- 28 unit tests (normalizeName + suggestEmailFix) all green via Node sanity.
## Deploy notes
- Re-run `pnpm db:generate` to regenerate the drizzle snapshot for 0011
(added the journal entry manually because no drizzle-kit on this box).
- Run `pnpm tsx scripts/backfill-user-names.ts --apply` against any DB not
yet canonicalised (already done for prod + dev today).
- The host-side Novu nodemailer-headers patch at
`postal/novu-patches/apply-headers-patch.sh` must be re-run after every
Novu container redeploy or the List-Unsubscribe header is silently dropped
before reaching Postal (see audit §9.1 #3 for the upstream cause).

Route all lifecycle/transactional emails through Novu
(api.bildirim.semih.ai, delivered via Postal). A framework-agnostic
client is shared by the NestJS API and the standalone BullMQ worker.
- welcome + referral on signup (better-auth user.create.after)
- email-verification + password-reset (auth.ts; token links never
track-wrapped so the one-time token survives)
- referral-qualified / referral-reward to the referrer on qualification
- payment-success / payment-failed in the Stripe webhook handlers
- trial-ending + win-back via a new daily lifecycle-email cron (worker),
idempotent via a 1-day endDate window (no sent-flag column)
- signed track.sase.tr CTA links when MAILTRACK_SECRET is set
- NOVU_* / APP_PUBLIC_URL / MAILTRACK_SECRET env added to config,
validation, .env.example and both compose service blocks

Reward engine:
- Recurring milestones (every 3 → +7d, every 5 → +14d) instead of one-time
tiers capped at 5; idempotent + transactional grants serialised per
referrer so concurrent qualifications can't double-count.
- Rewards now gated on the referred user's email verification
(afterEmailVerification hook); already-verified referees (OAuth) qualify
at apply time.
- Reward days banked as users.referral_credit_days when the referrer has no
live subscription, consumed on next trial start / activation (no more
silently lost rewards).
- Accurate cumulative rewardDays in stats; getMyReferrals returns referee
name/masked email/status.
Hardening / cleanup:
- onConflictDoNothing makes apply idempotent (no unhandled unique violation).
- Anti-fraud: normalizeEmail blocks self-referral via gmail dot/+tag aliases.
- Collision-safe referral code generation at signup.
- Single apply path (welcome onboarding modal); removed duplicate calls in
register + subscription pages. Input validation on the apply code.
Email verification UX:
- Verification link now lands on a dedicated /email-verified confirmation
page instead of the deep-linked VIN/search page.
Schema: referrals.status + qualified_at, users.referral_credit_days (0009).

Süper Panel Phase 7 — Phase B. Founder can suspend, reactivate, or ban a
Sase user from the panel. Status enforced in the AuthGuard so blocked
users can no longer make authenticated requests.
Schema (migration 0006)
- users.status varchar(20) default 'active' — active|suspended|banned
- users.status_reason text — free-text reason set on transition
- users.status_changed_at, status_changed_by uuid — audit metadata
- users_status_idx
Auth
- AuthGuard rejects 'suspended' / 'banned' with TR-localized message.
- auth.ts: declared `status` as a Better Auth additionalField so the
session.user object exposes it (matches how `role` is wired).
Endpoints (InternalTokenGuard)
- POST /internal/admin/users/:id/suspend { reason, founderId }
- POST /internal/admin/users/:id/reactivate { founderId }
- POST /internal/admin/users/:id/ban { reason, founderId }
Service
- LifecycleService.setStatus():
- refuses to touch admin-role users
- refuses no-op transitions (already in target state)
- refuses suspended→banned→suspended downgrade path (must reactivate first)
- on suspend/ban: deletes all sessions for the user (immediate sign-out)
- returns { from, to, sessionsKilled, changedAt }
Wiring
- LifecycleService + LifecycleController added to InternalAdminModule.
