Session Summary

Day 17 delivered on the promise at the end of Day 16: the real content work began. Four CLI tool deep-dive pages were created from scratch, the deep-dive index was updated to replace the “Coming Soon” placeholder with four live links, and all pages were validated with vnu. A minor HTML heading hierarchy issue (h4 following h2) was identified and resolved across the new pages using sed. The session also included a review of the pre-refactor site for content migration candidates.

Pages Created

Index Updated

deep-dive/deep-dive-index.html — The “Coming Soon” placeholder block in the AI for Unix/Linux section was replaced with four live hub-link cards matching the existing page style. Footer date typo (“MArch 3”) corrected to March 12, 2026.

vnu Validation

All four new pages validated with vnu. One class of issue found and resolved: h3 headings used inside two-column comparison boxes were originally coded as h4, triggering heading hierarchy warnings. Fixed across all affected files:

sed -i 's/<h4/<h3/g; s/<\/h4>/<\/h3>/g' filename.html

No other vnu errors. Pages validated clean after fix.

Pre-Refactor Content Review

Inventoried pre-refactor/ai-prev/ for content migration candidates. Files already pulled into the new site (via TMA/ links and direct references) were identified. Remaining candidates for future resources/ integration:

Review and integration deferred to a future session when building resources/.

Issues Noted for Follow-Up

Observations

The four CLI tool pages came together efficiently — consistent structure, consistent style, each with a distinct voice appropriate to the tool. The two-column Strengths & Limitations format proved particularly effective and will likely become a standard section for future tool pages.

The pre-refactor content review revealed that most of the substantive technical content is already linked into the new site via the TMA/ directory. What remains in pre-refactor is mostly unique personal content (Craig's assessments, AI self-reflection pieces) and reference materials — exactly the kind of content that belongs in resources/.

Day 17 efficiency note: four content pages plus an index update in a single session, with validation. The established workflow (tar upload → context restore → build → validate → diary) continues to perform well.
