+## BUG-074: Email Broken on K3s Production — SMTP Misconfigured
+- **Date:** 2026-02-18 13:00 UTC
+- **Severity:** CRITICAL
+- **Issue:** After K3s migration, production pods used old Docker code connecting to `host.docker.internal:25` (non-existent in K3s). The SMTP fix (commit 0902e1e) was on staging but not deployed to production.
+- **Root cause:** Three issues: (1) Production image at old commit without SMTP env var support, (2) K3s secrets pointed to mail.cloonar.com which rejected K3s worker IPs, (3) Old server Postfix only listened on localhost + Docker bridge, not public IP
+- **Fix applied:**
+  1. Updated K8s SMTP secrets to use old server (167.235.156.214) as relay (has DKIM for docfast.dev)
+  2. Added K3s worker IPs to old server's Postfix `mynetworks` and UFW rules (port 25)
+  3. Made Postfix listen on public IP (`inet_interfaces`)
+  4. Tagged v0.2.3 to deploy SMTP fix to production
+  5. Restarted all pods to pick up new secrets
+- **Verification:** `Verification email sent` confirmed in production logs
+- **Status:** ✅ FIXED
+
+## BUG-073: Staging Landing Page Shows Wrong Pro Plan Quota (2,500 vs 5,000)
+- **Date:** 2026-02-18 13:05 UTC
+- **Severity:** MEDIUM
+- **Environment:** Staging (https://staging.docfast.dev)
+- **Issue:** Staging landing page shows Pro plan as "2,500 PDFs per month" but production also shows "2,500 PDFs per month". Previous bugs (BUG-045, BUG-057) referenced 5,000 and 10,000 PDFs. The Stripe checkout page says "5,000 PDF conversions per month". There is a mismatch between what the landing page advertises (2,500) and what Stripe checkout says (5,000).
+- **Impact:** Customer confusion — they see 2,500 on the pricing page but 5,000 on the checkout page
+- **Fix:** Align landing page and Stripe product description to the same number
+- **Status:** OPEN

+- **K3s post-migration audit — found and fixed critical issues:**
+  - **BUG-074 CRITICAL: Email broken on K3s** — Production pods using old code (`host.docker.internal`). Fixed by:
+    1. Updated K8s SMTP secrets to relay through old server (167.235.156.214, has DKIM)
+    2. Added K3s worker IPs to old server's Postfix `mynetworks` + UFW rules
+    3. Made Postfix listen on public IP

+    5. Verified: email sent successfully from both production and staging
+  - **BUG-073 MEDIUM: Pro quota mismatch** — Landing page said "2,500" but code + Stripe enforce 5,000. Fixed landing page + JSON-LD. Tagged v0.2.4.
+- **CNPG database backups configured (DevOps agent):**
+  - MinIO deployed in-cluster as S3-compatible store for CNPG barman
+  - WAL archiving active with gzip compression
+  - Daily scheduled backup at 03:00 UTC, 7-day retention
+  - Manual backup verified successful
+- **Old Docker server decommissioned (DevOps agent):**
+  - Docker Compose app stopped, nginx stopped+disabled
+  - Files preserved in /root/docfast/ for reference
+  - Old server still used as SMTP relay (Postfix with DKIM)
+- **QA regression (QA agent):** 15/15 tests pass post-K3s migration
+- **Support:** Ticket #374 (internal test) closed
+- **Investor Test:** All 5 ✅
+- **Budget:** €181.71 remaining, Revenue: €9
