GAP School Module 01 — Foundation
Anchor outcome 745-second listing page loads → 0.4 seconds (1,800× improvement). 4× baseline throughput from infrastructure alone — before changing a single line of business logic.

The Anchor build started with a WordPress site on PHP 7.4 — end-of-life since November 2022. No real CDN. No WAF. Listing pages loading in 745 seconds. Phase 0 was a foundation fix, not a feature build. Four decisions made in two weeks produced a 4× throughput improvement before any application code changed. That's this module.

The 4 lessons

Each lesson documents one decision: the situation, what was done, why it matters, and what the Anchor build produced.
