Project Diary - Day 16 - March 11, 2026

Day 16 was a script refinement and final cleanup session. The session opened after a two-day break (Kinslee visit on March 10). Three successive improvements were made to check_ai_tree.sh to eliminate false positives, and the site reached a fully clean audit state — zero orphans, zero broken links — for the first time.

Script Improvements — check_ai_tree.sh

Fix 1: Line Numbers in MISSING Report

Added line numbers to every MISSING entry so broken links can be located instantly in the source file without hunting. Output now shows:

MISSING filename.html dir:/path line:47 -> broken-link.html

Implementation: switched from grep -oP to grep -nP and extracted line number via perl one-liner.

Fix 2: Multiple hrefs Per Line

The original script only captured the first href on each line. Lines with two links (common in callout boxes and nav sections) would produce a garbled second entry. Fixed by switching to a perl one-liner that extracts ALL hrefs from each line:

perl -ne 'my ($ln) = /^(\d+):/; while (/hréf="([^"]*)"/g) { print "$ln:$1\n" }'

Fix 3: hrefs Inside HTML Comments

The script was flagging href values inside commented-out blocks as MISSING links. Fixed by stripping comments before href extraction:

perl -ne 's///g; my ($ln) = /^(\d+):/; while (/hréf="([^"]*)"/g) { print "$ln:$1\n" }'

Final Orphan Cleanup

collaboration/addendum/2026-02-18-my-WWNTD-08.txt — had valid content, added link from Day 5 card in project-diary.html
collaboration/addendum/2026-03-03-my-WWNTD-12.txt — zero length file, deleted

Final Audit Result

Session Close Protocol — Established

Metric	Day 1 Baseline	Day 16 Final
Orphaned files	104	0
Broken links	34+	0
Script capability	index.html only	All HTML, line numbers, multi-href, comment-aware

Going forward, every session ends with:

Add diary card to collaboration/project-diary.html
Run check_ai_tree.sh -a /var/www/html/LessonPlans/AI/
Run vnu on the entire site
Tar key files for next session restart

Observations

The audit tooling is now genuinely production quality. Three iterations of script improvement — line numbers, multi-href handling, comment awareness — turned a good tool into a great one. The false positive problem that was masking real issues is fully resolved.

104 orphans on Day 1. Zero on Day 16. The housekeeping sprint that started as a "day off" on Day 14 has paid off completely. The site foundation is clean and ready for new content work.
