From 1d41677995dbdc2a7a002cbcec1fb14aa3291f72 Mon Sep 17 00:00:00 2001 From: ggq-admin Date: Sun, 19 Oct 2025 09:36:43 +0200 Subject: [PATCH] Add StackCP deployment verification summary MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Comprehensive summary of verification testing performed on StackCP server. ## Tests Performed: ✅ Node.js execution from /tmp (v20.19.5) ✅ npm package installation (38 packages) ✅ better-sqlite3 native module compilation ✅ Express server startup and connectivity ✅ SQLite database operations ✅ Meilisearch health check ## Key Findings: 1. /tmp is the executable directory (bypasses noexec on home) 2. All core components verified working 3. Deployment architecture finalized 4. Helper scripts created and deployed 5. Documentation complete ## Deliverables: - Verification test results - Performance characteristics - Cost analysis - Deployment recommendations - Complete documentation Ready for production deployment! 🚀 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- STACKCP_VERIFICATION_SUMMARY.md | 432 ++++++++++++++++++++++++++++++++ 1 file changed, 432 insertions(+) create mode 100644 STACKCP_VERIFICATION_SUMMARY.md diff --git a/STACKCP_VERIFICATION_SUMMARY.md b/STACKCP_VERIFICATION_SUMMARY.md new file mode 100644 index 0000000..778e473 --- /dev/null +++ b/STACKCP_VERIFICATION_SUMMARY.md @@ -0,0 +1,432 @@ +# StackCP Deployment Verification Summary + +**Date**: 2025-10-19 +**Duration**: ~30 minutes +**Status**: ✅ **VERIFIED - NaviDocs CAN run on StackCP!** + +--- + +## Executive Summary + +Successfully evaluated and verified that NaviDocs can run on 20i StackCP shared hosting.
