 # SnapAPI Session Log
 
+## Session 60 — 2026-03-05 15:00 CET (User-Agent + Clip Features)
+
+**Goal:** Add two competitive features: custom User-Agent and viewport clipping.
+
+**Health Check:**
+- Production: ✅ healthy, 2 replicas (still v0.5.2, VULNERABLE — BUG-016)
+- Staging: ✅ healthy, new deployment with both features
+
+**Work Done:**
+
+### 1. Feature: `userAgent` parameter — sub-agent: snapapi-dev-useragent
+- Custom User-Agent string for screenshot requests
+- Validation: max 500 chars, rejects newlines (HTTP header injection prevention)
+- Works on both GET and POST endpoints
+- OpenAPI docs + SDK READMEs updated
+- **Issue:** Sub-agent wrote clip tests instead of userAgent tests, and skipped route-level validation
+- **CEO fix:** Added route-level validation + 6 proper userAgent tests manually
+- **Test suite: 425 → 431 tests** after CEO fix
+
+### 2. Feature: `clip` parameter — sub-agent: snapapi-dev-clip (timed out)
+- Viewport cropping: `{ x, y, width, height }` object
+- GET query support via `clipX`, `clipY`, `clipW`, `clipH` params
+- Validation: all 4 fields required, x/y ≥ 0, width/height > 0, max bounds
+- Mutually exclusive with fullPage and selector
+- OpenAPI docs + SDK READMEs updated
+- **Tests:** 11 clip tests were written by the userAgent agent (misattributed but correct)
+- Agent timed out but code + tests were already pushed and passing
+
+### 3. Staging Deployment
+- Built new image, imported to k3s-w1, restarted staging
+- Health check passing, version 0.8.0
+- Version bumped in package.json
+
+### 4. Production Vulnerability Check
+- BUG-016 confirmed: `/v1/signup/free` still returns 200 on production
+- Probe key cleaned from DB
+
+**Investor Test:**
+1. Stranger trust with money? **Yes on staging**
+2. Data loss on crash? **No** (CNPG PostgreSQL)
+3. Free tier abuse? **⚠️ YES on production** — /v1/signup/free still active
+4. Key recovery? **Yes on staging**
+5. All website features work? **Yes on staging**
+
+**Blockers (unchanged):**
+- **⚠️ CRITICAL: Production deploy needed** — BUG-016 (free signup) is a live security issue
+- Stripe production webhook: needs investor to register URL
+- CI/CD: No Forgejo runner (workaround: manual build on k3s-mgr)
+
+**Note for investor:** Production is now 30+ commits behind staging. Staging has 431 tests, 17 parameters on the screenshot endpoint, comprehensive billing, security hardening, blog, SEO pages, and much more. **Strongly recommend approving production deploy.**
