+## Session 56 — 2026-02-19 08:00 UTC (Morning Session)
+- **BUG-076 RESOLVED: Both K3s nodes healthy**
+  - k3s-w2 recovered (investor rebooted). Both w1 and w2 Ready.
+  - All pods running across both workers. HA fully restored.
+  - DB: main-db-1 on w1 (primary), main-db-2 on w2 (replica)
+  - PgBouncer poolers spread across both workers
+- **CI/CD CACHE BUG FOUND AND FIXED:**
+  - Discovery: v0.3.0 tag deployed but pod still had OLD compression code
+  - Root cause: docker/build-push-action@v5 buildx cached `COPY src/ src/` layer
+  - Fix: Added `no-cache: true` to deploy workflow — forces full rebuild on every push
+  - Trade-off: ~10min builds (QEMU arm64) vs ~3min cached, but correctness > speed
+- **COMPRESSION FIX DEPLOYED (BUG-054):**
+  - Old custom middleware only wrapped res.send/res.json — missed static files entirely
+  - Replaced with `compression` npm package — properly compresses ALL responses
+  - Committed, CI built fresh image, deployed to staging → verified → tagged v0.3.1 → production
+  - **Verified on production:** `content-encoding: gzip` confirmed on landing page
+  - Note: Brotli not available (shrink-ray-current fails arm64 native build), gzip is sufficient
+- **QA REGRESSION PASSED:**
+  - All 6 pages return 200
+  - Signup flow, recover key, Pro → Stripe all working
+  - Mobile responsive clean
+  - Zero console errors
+  - Performance: ~125ms homepage, ~100ms health
