Calculator integrity
All construction calculator clusters remain registered with unique construction-specific slugs and practical material-estimation explanations.
Phase 12.8
Construction Production Quality Gate
This page records the production gate for the Construction platform before Phase 12.9 finalization: calculator integrity, platform compatibility, safety boundaries, crawl control, and release handoff.
Gate principle
Construction tools may help with planning, budgeting, and buying quantities, but final work must be checked against local building codes, supplier specifications, permits, and qualified professional judgment.
Production gate results
Platform compatibility
Phase 12.8 adds production-review pages only; it does not replace previous Finance, Health, Business, Education, Engineering, or Construction calculator modules.
Safety boundary
Pages continue to avoid final engineering, permit, structural, legal, or supplier-guarantee claims.
Crawl control
Public hardening pages are indexable monthly review assets; internal README, QA, manifest, and changelog files remain documentation assets.
Release handoff
README, QA report, changelog, release manifest, and deployment notes are included in the package.
Deployment confirmation
- Deploy Phase 12.8 to staging first and compare the Construction hub against the previous Phase 12.7 package.
- Open the Construction Production Hardening and Construction Production Quality Gate pages from the hub navigation.
- Run PHP syntax checks, JavaScript syntax checks, sitemap/index-control checks, and duplicate-slug scans after upload.
- Verify no existing Finance, Health, Business, Education, or Engineering page was removed or renamed.
- After production deployment, re-submit or refresh the sitemap and monitor Search Console for crawl/index changes.
