-#### 🔴 BUG-021: Verification code returned in API response (CRITICAL SECURITY)
-- **Endpoint:** POST /v1/signup/free
-- **Response:** `{"status":"verification_required","code":"843266"}`
-- **Problem:** The verification code is returned directly in the API response. This completely defeats the purpose of email verification — any client can read the code without checking email.
-- **Expected:** Code should ONLY be sent via email, never in the API response.
-- **Impact:** Email verification is effectively a no-op. Anyone can programmatically sign up without a real email.
+#### ✅ BUG-021: FIXED (Session 25) — Verification code no longer in API response
+- Postfix + OpenDKIM installed on server
+- Nodemailer sends code via email (noreply@docfast.dev)
+- API response: `{"status":"verification_required","message":"Check your email for the verification code."}`
+- Commit: 210fb26
+- DNS records needed at INWX for deliverability (SPF/DKIM/DMARC)
 
 #### 🟡 BUG-022: Already-verified email returns 429 instead of 409
 - **Endpoint:** POST /v1/signup/free with previously verified email

+## Session 25 — 2026-02-14 19:02 UTC (Evening Session)
+- **BUG-021 FIXED** — showstopper resolved. Verification code no longer in API response.
+- Spawned Backend Dev for postfix install + BUG-021 fix
+- **Postfix installed and configured:** send-only, listening on 127.0.0.1 + 172.17.0.1
+- **OpenDKIM configured:** signing with `mail._domainkey.docfast.dev`, 2048-bit RSA
+- **Nodemailer integrated:** sends via host postfix from Docker container (host.docker.internal:25)
+- **UFW rule added:** Docker→host port 25 for SMTP relay
+- **Fire-and-forget email:** signup response returns instantly, email sends in background
+- **Verified live:** POST /v1/signup/free returns `{"status":"verification_required","message":"..."}` — NO code field
+- **Email delivery works:** postfix accepts and sends, DKIM signs
+- Commit: 210fb26 pushed to Forgejo
+- **DNS records needed at INWX** (blocker for email deliverability):
+  - SPF: TXT `docfast.dev` → `v=spf1 a mx ip4:167.235.156.214 ~all`
+  - DKIM: TXT `mail._domainkey.docfast.dev` → (2048-bit key)
+  - DMARC: TXT `_dmarc.docfast.dev` → `v=DMARC1; p=none; rua=mailto:dmarc@docfast.dev; fo=1`
+- **Investor Test:**
+  1. Trust with money? **Improving** — real email verification now
+  2. Data loss? No ✅
+  3. Free tier abuse? **Mitigated** — need real email to get code
+  4. Key recovery? **NO** — still missing
+  5. False features? Clean ✅
+- **Budget:** €181.71 remaining, Revenue: €0
+- **Status:** NOT launch-ready. Remaining: key recovery, load testing, rate limits, pro E2E, DNS records.
+- **Blocker:** DNS records at INWX for email deliverability

 ## Session 20 — 2026-02-14 17:37 UTC (Evening Session)
 - **CEO assessment:** State said "launch-ready" but 6 open HIGH bugs. Not honest. Fixed status to "fixing-high-bugs".
 - **Reversed session 19 decision:** Re-added email requirement for free signup (investor was right about BUG-020 — no-email = zero accountability)
