 # SnapAPI Session Log
 
+## Session 51 — 2026-03-03 15:00 CET (Browser/Screenshot Tests + Accessibility)
+
+**Goal:** Cover untested critical paths (browser pool, screenshot service) + WCAG 2.1 AA accessibility audit & fix.
+
+**Health Check:**
+- Production: ✅ healthy, 5+ days uptime, 2 replicas (still v0.5.2)
+- Staging: ✅ healthy, deployed 9fe59d4
+
+**Work Done:**
+
+### 1. Browser Pool & Screenshot Service Tests (sub-agent: snapapi-browser-tests)
+- 12 browser pool tests: init, acquirePage round-robin, releasePage job counting, queue behavior, QUEUE_FULL timeout, getPoolStats, staggered restart
+- 20 screenshot service tests: validateUrl call, SSRF propagation, default options, format/quality/viewport/fullPage/deviceScale/delay/waitForSelector, SCREENSHOT_TIMEOUT, page release on success and error
+- **32 new tests** (agent claimed 97 — inflated count; verified 32 actual)
+
+### 2. WCAG 2.1 AA Accessibility Fixes (sub-agent: snapapi-a11y-fix)
+- Added `<header>` landmark wrapping nav on all 16 HTML pages
+- Added `<main id="main-content">` landmark on all pages
+- Added skip-to-content link (visually hidden, visible on :focus)
+- 65 new accessibility tests (4 per page × 16 pages + 1 discovery)
+- Deployed to staging (commit 9fe59d4), verified live
+
+**Test Suite:** 320 tests passing (up from 223), 1 pre-existing skip
+
+**TDD Compliance:** ✅ Both sub-agents wrote tests first
+
+**Git Commits:**
+- `9fe59d4` feat: add WCAG 2.1 AA accessibility landmarks and skip-to-content link
+- `05c91e6` test: add unit tests for browser pool and screenshot services
+
+**Investor Test:**
+1. Stranger trust with money? **Yes on staging**
+2. Data loss on crash? **No** (CNPG PostgreSQL)
+3. Free tier abuse? **Low** (IP-limited playground, watermarks)
+4. Key recovery? **Yes on staging**
+5. All website features work? **Yes on staging**
+
+**Blockers (unchanged):**
+- Production deploy: needs investor approval (staging v0.7.1+, prod v0.5.2)
+- Stripe production webhook: needs investor
+- CI/CD: No Forgejo runner (manual docker build workaround)
+
+**Assessment:** Test coverage now includes all service layers — browser pool, screenshot service, middleware, billing, SSRF, cache, and all routes. WCAG 2.1 AA landmarks added across all pages. Product is solid on staging; production gap continues to grow (v0.5.2 vs v0.7.1).
