The search index built in three seconds. Five phases made that possible.

Pagefind took an afternoon to wire up. The navigation phases before it took a week. A search index returns what’s there — and what needed to be there first was structure.

The cheapest phase in a seven-phase plan was also the highest-leverage one

Prerequisite chips in the learning hub — three words, one arrow, no JavaScript — outperformed every other navigation phase by the only metric that matters at the chapter level: whether a reader knows what to read first. The evidence is what the other six phases cost by comparison.

Pagefind shipped last. The prerequisite chips had already closed the harder problem.

The learning hub's navigation plan ran seven phases and ended with site-wide Pagefind search. The highest-leverage phase was five: a three-word chip at each chapter head pointing to the one thing to read first. By the time search shipped, most readers who needed it no longer did.

The read-first chip outperformed the TOC, track sections, and site-wide search

The learning hub navigation programme ran six phases across two days: track sections, a scroll-spy TOC, prerequisite chips, and site-wide Pagefind search. The smallest phase shipped fifth and delivered more navigability than all the rest combined. The structural reason was there in the spec before the build started.

Seven phases in. The chip at the chapter head was still the highest-leverage fix.

The learning hub navigation programme shipped complete last week: seven phases, P0 through P6, from breadcrumb to site-wide Pagefind search. Improving on the earlier post that identified the prerequisite chip as the spec's highest-value navigability fix — having shipped P4's IntersectionObserver scroll-spy and P6's full search index, the designation holds. Here's what shipping the full programme makes visible.
