+# Validation Run: Crystal Blue Plumbing Heating & Air
+
+**Date:** 2026-08-14
+**Business:** Crystal Blue Plumbing Heating & Air
+**Location:** Placerville, CA (actual: Loomis, CA — same metro area)
+**Why chosen:** Plumbing/HVAC (GTM vertical), Placerville/Cameron Park area, never audited before, multi-location chain (tests GBP disambiguation)
+
+## Pipeline Execution
+
+```
+multi_scraper.py → audit_engine.py → findings.json + findings.md
+```
+
+## Surface Results
+
+| Surface | Status | Notes |
+|---------|--------|-------|
+| Google Business Profile | ⚠️ Degraded | Returned `name: "Hours"`, null address, null phone. GBP matched wrong entity. |
+| Apple Maps | ✅ Good | Full NAP, 4.2★/65 reviews, hours, website URL, phone |
+| Bing Places | ❌ Failed | Returned no data |
+| Website | ❌ Failed | HTTP 403 Forbidden (crystalblueplumbing.com) |
+
+## Key Findings (5 total)
+
+| # | Severity | Finding | Verdict |
+|---|----------|---------|---------|
+| 1 | 🟥 Immediate | Hours mismatch (GBP vs Apple) | **FALSE POSITIVE** — GBP from wrong entity |
+| 2 | 🟧 High | No website found | PARTIALLY FALSE — URL exists but 403 |
+| 3 | 🟨 Medium | Review dates unavailable | VALID |
+| 4 | 🟨 Medium | No description | VALID |
+| 5 | 🟩 Enhancement | No price level | VALID |
+
+## Issues Observed
+
+### 1. GBP Entity Disambiguation (CRITICAL)
+GBP scraper returned `name: "Hours"` with null address. Matched wrong GBP listing. Fallback to Apple Maps saved the audit.
+
+### 2. Apple Maps Hours Parsing
+`12:00 AM-12:00 PM` for all days — likely parsing "Open 24 hours" as midnight-to-noon.
+
+### 3. Website 403 Not Distinguished From "No Website"
+Should be separate findings: "no_website" vs "website_unreachable".
+
+### 4. Hours Mismatch With Degraded Source
+Engine flagged hours mismatch but GBP data was garbage. Mismatch detection should skip degraded sources.
+
+## Verdict
+
+Pipeline works end-to-end but findings not yet trustworthy without human review. GBP scraper is the biggest risk.
+
+**Before production:**
+1. GBP entity validation (name match + address present)
+2. Hours comparison skip degraded sources
+3. Website 403 → distinct finding
+4. Apple Maps hours parsing audit
