- Replace <div class="tfe-layout"> with <article>, <div class="tfe-left"> with
<header>, <div class="tfe-right"> with <aside> (supplementary media column)
- Fix inverted heading hierarchy: <h1> is now the thesis title (primary topic);
author demoted to <p class="tfe-author"> (metadata, not a heading)
- Replace <div class="tfe-meta-list"> / <div class="tfe-meta-item"> / <span class="label">
/ <span class="value"> with <dl> / <dt> / <dd> (WCAG 1.3.1 info & relationships)
- Replace <div class="tfe-media-block"> with <figure>; <p class="tfe-file-caption">
with <figcaption>; PDF <embed> gets .tfe-pdf-fallback download link (WCAG 4.1.2)
- Move back link to top of left column; extract inline styles to .tfe-back-link,
.tfe-note-value, .tfe-restricted CSS classes
- Fix image alt text: description column used when populated, fallback to
"Title — Author" instead of raw filename (WCAG 1.1.1)
- Add sr-only new-tab warning on baiu_link (WCAG 1.3.1 / 2.4.4)
- Fix PDF embed height: clamp(300px, 80vh, 700px) prevents horizontal overflow
on small screens (WCAG 1.4.10 reflow)
- tfe.css: update all selectors to match new structure; remove inline styles;
unify .tfe-restricted and .tfe-no-files; add .tfe-pdf-fallback, .tfe-back-link
- Add idx_theses_pub_year composite index on theses(is_published, year DESC) to
schema.sql; replaces the need for the query planner to pick between the two
separate idx_theses_published / idx_theses_year indexes and sort with a temp
B-tree. Every public query filters on is_published=1 and orders/filters by year,
so this covering index eliminates the sort pass for those queries.
- Create storage/migrations/006_add_composite_index.sql and apply to both
posterg.db and test.db.
- Fix storage/migrations/005_add_banner.sql: the view recreation in that file
still referenced the pre-migration-001 table/column names (thesis_keywords,
keywords.keyword). Updated to use thesis_tags / tags tg to match the canonical
schema.sql. The live DB was unaffected (migration 001 ran before 005), but the
file was misleading and would fail if ever re-run from scratch.
